Abstract:
Vegetation cover can regulate regional climate and associated dry–wet variations. However, the effects of the quantitative structure and landscape pattern of vegetation cover on climatic drought remain unclear. Yunnan Province in China, with its abundant vegetation resources, provides a good setting for addressing this research gap. Our objective is to provide guiding recommendations for climate-warming mitigation through the study of the topic. This study adopted four periods of vegetation cover data, from 1992 to 2020, and explored their dynamics. Monthly average precipitation and temperature data from 125 meteorological stations in Yunnan were used to calculate standardized precipitation–evapotranspiration index (SPEI) for 1992–2020 to understand the responses of climatic drought to vegetation cover dynamics. The correlations between quantitative structure, landscape pattern, and climatic drought were investigated by Pearson’s correlation coefficient in 10 km, 20 km, 30 km, and 40 km grid cells, respectively. The results indicate that changes in the quantitative structure of vegetation could influence regional climates, with the contributions to climatic drought mitigation ranked in the following order: broad-leaved forest > shrubland > needle-leaved forest > cropland > grassland. Landscape patterns significantly affected local climates, where broad-leaved and needle-leaved forests had the strongest and most stable correlations with climatic drought, whereas shrubland and grassland showed weaker correlations. The correlations between landscape patterns and climatic drought were stronger during the dry season than the rainy season. Factors such as the landscape dominance index, fragmentation index, and aggregation index had a significant impact on climatic drought. The dominant and aggregated-distribution broad-leaved forests were conducive to climatic drought mitigation, while needle-leaved forests, croplands, and grasslands might exacerbate climatic drought.

Abstract:
Climatic maps have been very difficult to generate in Nigeria, not because of lack of knowledge or expertise, but due to dearth of climatic data. Most of the existing climatic maps are either not reliable or too generalized since Nigerian Meteorological Agency (NIMET) climatic data which is the only reliable climatic data are available only in the state capitals and which were often used to generate climatic maps. In this study, DivaGIS, WorldClim, NASA Power Project and globalweather climatic data of rainfall, temperature, relative humidity and solar radiation were used to generate the spatial patterns, trends and seasonal pattern of each of the aforementioned climatic elements in Taraba State Central District; comprising Bali, Gassol, Gashaka, Gembu, Kurmi and Sardauna LGAs. The results were presented in charts and using the bar chart and the kringing tools of Microsoft Excel package and ArcGIS 10.5 software respectively. Spatial pattern of rainfall of the area revealed that the rainfall pattern are influenced by relief and latitudes as Sardauna which is on the plateau in the South has more rains than Gassol in the North. Mountainous and highland areas were also found to have higher rainfall than the immediate environment. Trends in rainfall was decreasing in Bali, Gashaka and Sardauna LGAs. Rainfall is high from June to September when minimum of 200 mm monthly rainfall are received in all the five LGAs. The spatial pattern of temperature is inversely related to that of rainfall, while trends in temperature is increasing in all the LGAs. Relative humidity has similar spatial/seasonal patterns with that of rainfall, but showing decreasing trends in all the LGAs except Kurmi LGA. The spatial pattern of solar radiation was found to be affected by the aspects of the area as Kurmi LGA at the western side recorded highest amount of solar radiation. The pattern of solar radiation in the study area is seasonal because solar radiation is low (less than 20 mj/m2) in all the LGAs except Kurmi during the rainy season (June – October). It was recommended that ground station climatic data which covers larger areas than in-situ climatic data that are only available in State capitals should be encouraged among the climate analysts to alleviate the problems associated with dearth in in-situ climatic data.

Abstract:
Climate is critical for plant altitudinal distribution patterns. Non-climatic factors also have important effects on vegetation altitudinal distribution in mountain regions. The purpose of this study was to explore the current distribution of plant diversity along the altitudinal gradient in the Taihang Mountain range of northern China and to estimate the effects of climatic and non-climatic factors on the elevational pattern. Through a field survey, a total of 480 sampling plots were established in the central Taihang Mountain range. Alpha diversities (the Shannon–Weiner index and Simpson index) and beta diversities (the Jaccard index and Cody index) were measured based on the survey data. Plant community structure change based on the altitudinal gradient was explored by measuring the diversity indices. Canonical correspondence analysis was carried out to determine the factors influencing plant altitudinal distribution. The contributions of climatic and non-climatic factors on plant distribution were determined by partial methods. The results showed that the plant diversity of the elevational gradient complied with a “hump-shaped” pattern, in which communities in the medium altitude area with higher plant diversity had a higher species turnover rate, and non-climatic factors, particularly the anthropogenic factors, had an important influence on the plant altitudinal pattern. In conclusion, climatic and non-climatic factors both had important effects on the plant altitudinal pattern. It is strongly recommended to reduce human interference in mountain vegetation protection and management.

Abstract:
Abstract Multiple hypotheses have been proposed to explain the variation of dorsal patterns observed in snakes, but no studies yet have tested them over broad taxonomic and geographical scales. The Viperidae offer a powerful model group to test eco-evolutionary processes that lead to disruptive and cryptic ornaments. We developed a database reporting dorsal ornamentation, ecological habitus, habitat features and climatic parameters for 257 out of 341 recognized species. Three patterns of dorsal ornamentation were considered: “zig-zag”, “blotchy” and “uniform” patterns. Phylogenetic comparative analyses were based on 11 mitochondrial and nuclear genes. Forty-eight species presented a zig-zag pattern type, 224 a blotchy pattern type and 32 a uniform pattern type. All the patterns showed a strong phylogenetic signal. Character phylogenetic reconstruction analyses suggested an ancestral state for blotchy ornamentation, with multiple independent evolutions of the other patterns. The blotchy pattern was more frequent in terrestrial species living in warm climates and sandy habitats, supporting the hypothesis of a disruptive function. The zig-zag pattern evolved independently in several isolated taxa, particularly in species living in cold climates and in dense vegetation or water-related habitats, supporting the hypothesis of disruptive and aposematic functions. Uniform coloration was particularly frequent in arboreal species, supporting the hypothesis of a cryptic function.

Abstract:
We studied regional variation in growth-limiting factors and responses to climatic variability in subalpine forests by analyzing growth patterns for 28 tree-ring growth chronologies from subalpine fir (Abies lasiocarpa (Hook.) Nutt.) stands in the Cascade and Olympic Mountains (Washington and Oregon, U.S.A.). Factor analysis identified four distinct time series of common growth patterns; the dominant growth pattern at any site varied with annual precipitation and temperature (elevation). Throughout much of the region, growth is negatively correlated with winter precipitation and spring snowpack depth, indicating that growth is limited primarily by short growing seasons. On the driest and warmest sites, growth is negatively correlated with previous summer temperature, suggesting that low summer soil moisture limits growth. Growth patterns in two regions were sensitive to climatic variability associated with the Pacific Decadal Oscillation, apparently responding to low-frequency variation in spring snowpack and summer soil moisture (one negatively, one positively). This regional-scale analysis shows that subalpine fir growth in the Cascades and Olympics is limited by different climatic factors in different subregional climates. Climate–growth relationships are similar to those for a co-occurring species, mountain hemlock (Tsuga mertensiana (Bong.) Carrière), suggesting broad biogeographic patterns of response to climatic variability and change by subalpine forest ecosystems in the Pacific Northwest.

Abstract:
Understanding the pattern of species distribution and the underlying mechanism is essential for conservation planning. Several climatic variables determine the species diversity, and the dependency of species on climate motivates ecologists and bio-geographers to explain the richness patterns along with elevation and environmental correlates. We used interpolated elevational distribution data to examine the relative importance of climatic variables in determining the species richness pattern of 26 species of gymnosperms in the longest elevation gradients in the world. Thirteen environmental variables were divided into three predictors set representing each hypothesis model (energy-water, physical-tolerance, and climatic-seasonality); to explain the species richness pattern of gymnosperms along the elevational gradient. We performed generalized linear models and variation partitioning to evaluate the relevant role of environmental variables on species richness patterns. Our findings showed that the gymnosperms’ richness formed a hump-shaped distribution pattern. The individual effect of energy-water predictor set was identified as the primary determinant of species richness. While, the joint effects of energy-water and physical-tolerance predictors have explained highest variations in gymnosperm distribution. The multiple environmental indicators are essential drivers of species distribution and have direct implications in understanding the effect of climate change on the species richness pattern.

Abstract:
SUMMARYStudies of temporal and spatial patterns of diarrhoeal disease can suggest putative aetiological agents and environmental or socioeconomic drivers. Here, the seasonal patterns of monthly acute diarrhoeal morbidity in Thailand, where diarrhoeal morbidity is increasing, are explored. Climatic data (2003–2006) and Thai Ministry of Health annual reports (2003–2009) were used to construct a spatially weighted panel regression model. Seasonal patterns of diarrhoeal disease were generally bimodal with aetiological agents peaking at different times of the year. There is a strong association between daily mean temperature and precipitation and the incidence of hospitalization due to acute diarrhoea in Thailand leading to a distinct spatial pattern in the seasonal pattern of diarrhoea. Model performance varied across the country in relation toper capitaGDP and population density. While climatic factors are likely to drive the general pattern of diarrhoeal disease in Thailand, the seasonality of diarrhoeal disease is dampened in affluent urban populations.

Abstract:
The Tibetan Plateau (TP) vegetation plays an important role in the local ecosystem, which responds significantly to climate change and can affect local and large-scale weather and climate anomalies. However, little attention has been paid to its year-to-year variation. In this paper, using two NDVI datasets (GIMMS and MODIS) originated from satellite remote sensing, the variability characteristics of NDVI over the TP on the interannual time scale and associated local climatic factors were investigated. The results show that two primary patterns of NDVI governed TP during the main growing season (June–September, JJAS) for the period 1982–2020. The first one is a uniform pattern, with a consistent spatial variation over the entire TP, and the second is a dipole pattern, with an out-of-phase spatial variation of NDVI between the northern and southern TP. Interannual variations of the different climatic factors regulate the NDVI variability over the different regions of the TP. The interannual variability of the uniform NDVI pattern is mainly affected by the two local climatic factors, the preceding May–August precipitation and simultaneous JJAS sunshine duration. Specifically, NDVIs over the southern and eastern TP have a more significant response to the preceding precipitation and simultaneous sunshine duration, respectively. The variability of the dipole NDVI pattern is primarily modulated by the preceding May–August precipitation and simultaneous surface air temperature, ground surface temperature, and sunshine duration. However, NDVIs over the northern and southern TP have different degrees of response to the four climatic factors, with the most significant response being to preceding precipitation. The combined effect of these factors contributes to the formation of the interannual variability in the uniform and dipole patterns. This paper may shed light on deeply understanding the reasons for the inconsistency in variations of vegetation over the different regions of the TP under climate change. In addition to the effect of local climatic factors that this study focuses on, the influence of external climatic factors on the variability of the TP NDVI deserves further research in the future.

Abstract:
The average size of Australian farms in scale and revenue are the globe’s largest. This scale is a result, in part, of low average rural population densities; development patterns in broadacre production; low levels of effective public policy transfers; a stable and suitable institutional setting suitable for corporate and other large scale investment; and low yields. It is also a factor of the natural variability of the country’s climatic systems which have contributed to the scale of extensive northern cattle production; this variability has implications for the pattern of ownership of broadacre and extensive production. Corporate ownership, tends to concentrate production aggregations at sufficient scale to offset its additional overheads in areas of relative climatic stability and to replicate these agroholding aggregations spatially to protect the stability of revenue flows. Family structures are more dominant in areas of greater climatic variability. Of interest is the impact that any increasing climatic variability (versus rapid changes in technology) may have upon this pattern.

Considerando os Domínios do Cerrado e Amazônico no Brasil e a área de transição entre eles, investigamos os padrões de similaridade e de gradientes (Capítulo 1), de diversidade alfa (Capítulo 2) e de distribuição geográfica potencial (Capítulo 3) da flora arbórea e suas correlações com variáveis ambientais e estruturas espaciais. Aplicamos análises multivariadas, estimativas de diversidade de espécies, modelos lineares gerais e ferramentas espaciais, incluindo análise de autocorrelação espacial e modelagem de distribuição geográfica de espécies, sobre dados florísticos e ambientais em um banco de dados constituído por 90 levantamentos. No Capítulo 1, encontramos que a conexão entre os Domínios ocorre como um gradiente fortemente correlacionado com a precipitação anual, opondo climas pluviais (Domínio Amazônico) a climas continentais (Domínio do Cerrado). As florestas de várzea amazônicas constituem um bloco florístico isolado e a grande área de Transição mostra afinidade florística a ambos os Domínios. A flora tem forte padrão espacial: autocorrelaciona-se positivamente a curtas distâncias e negativamente a grandes distâncias, indicando diminuição da similaridade com o aumento da distância geográfica. O diâmetro do tronco do menor indivíduo incluído na amostra (DMI) também foi uma variável importante para explicar a variação florística. No Capítulo 2, a diversidade alfa correlacionou-se significativamente com variáveis de precipitação e de temperatura, mostrou-se influenciada pelo espaço e apresentou correlação significativa com o DMI. Alguns resultados dos modelos globais foram aparentemente contraditórios com a literatura e decorrem, pelo menos em parte, de variações locais. No Capítulo 3, detectamos que espécies do Cerrado, influenciadas primariamente pela sazonalidade de precipitação, seriam encontradas principalmente na Floresta Semidecídua Atlântica, no sudeste do Brasil, e espécies amazônicas, influenciadas predominantemente por variáveis térmicas, seriam encontradas em outras florestas pluviais do norte e noroeste da América do Sul e em algumas áreas sazonalmente secas, inclusive no Brasil Central, onde predomina o Domínio do Cerrado. As principais conclusões desta Tese foram: 1) A flora arbórea desses Domínios e da transição apresenta forte padrão espacial, que segue um gradiente linear em grande escala separando parte considerável das floras dos dois Domínios. 2) A variação de diversidade alfa não foi significativa entre os Domínios e a Transição, indicando que transições em larga escala não necessariamente representam áreas de maior diversidade que os Domínios adjacentes. 3) Além das variáveis geoclimáticas, o diâmetro do menor indivíduo incluído na amostra também foi um importante preditor dos padrões de similaridade e diversidade alfa ao longo da área de estudo, mas o mesmo não ocorreu com o número de indivíduos amostrados. 4) Conforme alguns autores já haviam indicado, é possível encontrar elevada performance de modelos de distribuição potencial mesmo para espécies com número relativamente baixo de registros (<25). 5) A adequabilidade climática de espécies amazônicas em parte do Domínio do Cerrado suporta a hipótese de expansão da Floresta Amazônica, que ocorreria desde o Pleistoceno e acompanharia as flutuações climáticas de períodos secos e frios a períodos quentes e úmidos<br>Abstract: In South America, little is known about the floristic links between forests and savannas domains. Considering the Cerrado and Amazonian Domains in Brazil and the transition area between them, we investigated the patterns of similarity and gradients (Chapter 1), alpha diversity (Chapter 2) and potential geographical distribution (Chapter 3) of the tree flora and its correlations with environmental variables and spatial structures. We applied multivariate analysis, estimates of species diversity, general linear models and spatial tools, including spatial autocorrelation analysis and modeling of species geographic distribution, on floristic and environmental data in a database consisting of 90 surveys. In Chapter 1, we found that the connection between the Domains occurs as a gradient strongly correlated with the annual precipitation, opposing pluvial (Amazonian Domain) to continental climates (Cerrado Domain). Amazonian floodplain forests constitute an isolated block and the large transition zone presents floristic affinities with both Domains. The flora has a strong spatial pattern, positively autocorrelated over short distances and negative autocorrelated at large distances, indicating decreasing similarity with increasing geographic distance. The trunk diameter of the smallest individual sampled (DSI) was also an important variable to explain the floristic variations. In Chapter 2, the alpha diversity correlated significantly with precipitation and temperature variables, was influenced by the space and showed significant correlation with DSI. Some results of global models were apparently contradictory to the literature and result from local variations, at least in part. In Chapter 3, we detected that Cerrado' species, primarily influenced by the precipitation seasonality, would be found mainly in the Atlantic Semideciduous Forest in southeastern Brazil, and amazonian species, influenced predominantly by thermal variables, would be found in other rain forests of the north and northwest of South America and in some seasonally dry areas, including Central Brazil, where Cerrado Domain predominates. The main conclusions of this thesis were: 1) The tree flora of these Domains and the transition has a strong spatial pattern, which follows a large-scale linear gradient separating considerable proportion of the flora of both Domains. 2) The variation in alpha diversity was not significant between both Domains and Transition, indicating that large-scale transitions do not necessarily represent more diverse areas than the adjacent Domains. 3) Besides the geoclimatic variables, the diameter of the smallest individual sampled was also an important predictor of similarity and alpha diversity patterns along the study area - this did not occur with the number of individuals sampled. 4) According to some authors have stated, it is possible to find high-performance models of potential distribution even for species with relatively low number of records (<25). 5) The climatic suitability of Amazonian species in part of the Cerrado Domain supports the hypothesis of expansion of the Amazonian Rainforest, which would occur since the Pleistocene climatic fluctuations and accompany dry and cold periods to hot and humid ones<br>Doutorado<br>Biologia Vegetal<br>Doutor em Biologia Vegetal

Abstract:
Global climatic change as well as its consequences such as extreme weather events and sea-level rising has become a focusing issue in the contemporary world. Alpine snow cover is increasingly regarded as a good and sensitive indicator of climatic change due to the less direct interference by human. In western aridzone of China, majority of mountainous areas are covered by snow in winter seasons. This region is one of the most important seasonal snow cover regions in China and also a typical alpine snow cover region in the mid-high latitudes of the Northern Hemisphere. Being less affected by economic development and human activities in the history, the change of permanent and seasonal snow cover in this region echoes the global climatic and environmental change. In addition, snow melt water, which provides the major water supply in the region, is vital for living beings in the arid and harsh environment. It is therefore necessary to understand the snow cover change during the past decades. This study aims to investigate the spatio-temporal pattern of snow cover in the western aridzone of China in the past 30 years by using remote sensing technology and to analyze the relationship between the change of snow cover and global climate. The reliability of remote sensing-derived global snow data is firstly examined. Data consistency and accuracy are assessed against the ground measurements. In order to undertake a down-scale snow depth analysis with other high-resolution environmental data, a method that fuses the low-resolution passive microwave and high-resolution optical snow cover images is proposed. A linear mixture model is adopted in spectral unmixing for modifying snow depth estimates. Time series analysis method is utilized to describe the long-term trend and periodic features. The analysis is applied not only to the whole region but also to the local scale represented by a pixel so that the spatial pattern of the change can be illustrated. Using the result and climatic data, the relationship between snow cover and global/regional climatic change is established. The results make contribute to the understanding of the impacts of climatic change, at regional level, on the spatio-temporal pattern of snow cover in the western aridzone of China.

Considerando que estudos sobre fenologia vegetal são importantes para a compreensão do funcionamento e verificação da ocorrência de padrões no ciclo vegetativo das plantas, resultando em melhorias nas atividades de conservação e manejo, o objetivo desta pesquisa foi caracterizar a dinâmica fenológica de diferentes tipologias campestres no estado do Rio Grande do Sul (RS), a partir da relação entre a variabilidade de elementos climáticos intra e interanual e eventos em larga escala e a distribuição espaço-temporal das tipologias predominantes. A área de estudo abrangeu 10 tipologias predominantes de campo no estado do RS. A base de dados orbitais utilizada foi obtida de diferentes produtos relacionados ao estudo da vegetação do sensor MODIS (Moderate Resolution Imaging Spectroradiometer), constando os índices de vegetação NDVI (Normalized Difference Vegetation Index), EVI (Enhanced Vegetation Index) e GPP (Gross Primary Productivity). Também, foram utilizados dados meteorológicos provenientes da base TRMM (Tropical Rainfall Measuring Mission) e ERA Interim, para o período de fevereiro de 2000 a dezembro de 2014. O uso de séries temporais de dados NDVI e EVI/MODIS permitiram obter informações sobre a fenologia da vegetação campestre e a definição de padrões diretamente relacionados a variações meteorológicas. A sazonalidade da vegetação campestre apresenta cliclo anual bem marcado, com início e fim da estação de crescimento determinada pelas condições térmicas (temperatura do ar), porém alterado pela disponibilidade hídrica. A relação entre temperatura do ar e vigor vegetal apresentou maior correlação e tem influência direta sobre o início e fim da estação de crescimento (primavera e verão) A precipitação pluvial, no entanto, influencia as condições de crescimento/desenvolvimento das tipologias campestres, especialmente no verão, associado aos períodos de estiagem que tendem a ocorrer com maior frequência. Ambos os índices (EVI e NDVI) apresentam maior variabilidade durante a primavera e o verão, com diminuição da variabilidade durante o outono e inverno. A aplicação da Transformada de Ondaleta mostrou onde e quando ocorreram alterações no padrão fenológico da vegetação campestre e a Transformada Coerência apontou a intensidade (correlação) entre os índices de vegetação e a variabilidade das condições meteorológicas. O agrupamento das tipologias, com uso da técnica de Cluster, revelou seus comportamentos sazonais, sendo que a partir do índice EVI há a possibilidade de identificar diferenças entre as tipologias durante o outono e inverno, enquanto o NDVI apresentou diferença somente no inverno. As métricas fenológicas obtidas do Timesat para as imagens EVI permitiram obter dados importantes sobre o ciclo fenológico da vegetação campestre do RS, com a caracterização do padrão fenológico das tipologias predominantes. O uso de modelos para a estimativa da produtividade da vegetação campestre a partir do EVI revelou dentre as tipologias testadas que a CSR (campos de solos rasos) apresentou maior capacidade de explicar a variabilidade da produtividade dos campos por ser mais suscetível às variações meteorológicas. Os resultados obtidos permitiram confirmar a diversidade entre as tipologias campestres predominantes no RS, expressas por índices de vegetação, tanto no aspecto temporal como espacial. O uso dos índices de vegetação demonstrou potencial no monitoramento do padrão fenológico da vegetação campestre frente a variabilidade climática do RS.<br>Considering that studies on vegetal phenology are important to understand the mechanisms and pattern recognition on the vegetative cycle of plants, resulting in improvements in conservation and management activities, the aim of this research was to characterize the phenological dynamics of different grassland typologies in Rio Grande do Sul State (RS), based on the relationship between the variability of intra-annual and inter-annual climatic elements, large-scale events and the spatio-temporal distribution of predominant typologies . The study area included 10 predominant grassland typologies in RS state. The orbital database used was obtained from different products related to vegetation studies of MODIS sensor (Moderate Resolution Imaging Spectroradiometer), presenting the vegetation indices NDVI (Normalized Difference Vegetation Index), EVI (Enhanced Vegetation Index) and GPP (Gross Primary Productivity). Also, meteorological data from TRMM base (Tropical Rainfall Measuring Mission) and ERA Interim were used for the period of February 2000 to December 2014. The use of time series data from NDVI and EVI/MODIS led to information on grassland vegetal phenology and the definition of patterns directly related to meteorological variations. The seasonality of grassland vegetation presents a well marked annual cycle, with the beginning and the end of growing season determined by thermal conditions (air temperature) but altered by water availability. The relationship between air temperature and vegetal vigor presented a strong correlation and influences directly on the beginning and on the end of the growth season (spring and summer). The rainfall, however, influences growth/development conditions of grassland typologies, especially in summer, associated to drought periods that tend to occur more frequently Both indices (EVI and NDVI) presented a greater variability during spring and summer, with a lesser variability during fall and winter. The application of Ondaleta Transform showed where and when alterations occurred in the phenological pattern of grassland vegetation and the Coherence Transform pointed the intensity (correlation) between vegetation indices and the variability of meteorological conditions. The grouping of typologies, using the Cluster technique, revealed their seasonal behaviors, and from the EVI index there is the possibility of identifying differences between typologies during fall and winter, whereas NDVI showed differences only in winter. The phenological metrics obtained from Timesat to EVI images allowed to obtain important data on the phenological cycle of grassland vegetation of RS state, with a characterization of the phenological pattern. The use of models for estimation of productivity of grassland vegetation based on EVI revealed among the typologies tested that the CSR (shallow soils grasslands) presented greater ability to explain the variability of grasslands productivity because it is more susceptible to meteorological variations. The obtained results allowed for the confirmation of diversity among the grassland typologies predominant in RS state, expressed by vegetation indices, both in temporal and spatial aspects. The use of vegetation indices demonstrated potential on the monitoring of phenological pattern of grassland vegetation considering the climatic variability of RS state.

Abstract:
Mapping and explaining the distribution of vegetation helps land managers to make systematic conservation planning decisions. This is typically achieved using models that correlate the distribution of species with environmental factors, and can predict the vegetation at unsurveyed locations. These Species Distribution Models (SDMs) have numerous unresolved issues, but serve as a useful first-pass approximation for planning purposes.This thesis investigates some of the uncertainties of SDMs, including the impact of data accuracy, the incorporation of spatial processes, the evaluation of alternative models, and the benefits and challenges of producing models at the landscape scale. The research was conducted on the Illawarra Escarpment, 80 km south of Sydney, Australia (34.4 oS, 150.9 oE). The escarpment contains a north-south trend in eucalypts (Eucalyptus spp.) that cannot be explained in terms of elevation or geology. It also exhibits a patchy distribution of rainforest communities, some unique to the Illawarra. It is not known which environmental factors determine the distribution of either the eucalypts or rainforest species, or how they may respond to a changing climate.Species distributions are sensitive to the accuracy of data used, and yet many models only use elevation as a surrogate for temperature, or use simple elevation sensitive interpolations from weather stations. I collected hourly temperature data from 40 sites on the Illawarra Escarpment, and investigated whether elevation was an adequate surrogate for temperatures in this landscape. I then investigated whether temperature surfaces could be improved by considering other topographic and geographic factors, including exposure to wind, distance to coast, radiation, and the average conditions in the surrounding neighbourhood. Elevation was well correlated with moderate seasonal temperatures (e.g. summer minima and winter maxima), but was poorly correlated with the extreme temperatures (summer maxima, winter minima) that are physiologically limiting for many species. Using neighbourhood influences, exposure to wind and distance to coast improved the accuracy of temperature surfaces, and increased the explanatory performance of vegetation models. I concluded that elevation was not always an adequate surrogate for temperature. Temperatures are also affected by other topographic and geographic factors, and these should be considered when developing models for systematic conservation planning activities.Species distribution models are typically based solely on niche factors. Where spatial processes are included, it is typically by employing autologistic regression, or other techniques that use survey data as a predictor. This precludes the models being used to make predictions in times or places where survey data is unavailable, and reduces ecological explanation because it is an interpolation technique. I used neighbourhood (contextual) indices based on environmental factors as an alternative method to overcome these problems. I demonstrate that contextual indices improve SDMs over purely niche-based models, and are capable of predicting unknown populations in unsurveyed areas. I conclude that contextual indices have numerous advantages over autologistic regression, and can capture a continuum between niche and dispersal limited species.Models that predict how species will respond to climate change either use coarse-scale climate surfaces, or idealised predictions of uniform warming. These methods may dramatically over-estimate extinction risk because they neglect fine-scale variations in warming, and refugia where species can persist despite unfavourable regional conditions. I created fine-scale estimates of warming by combining 35 years of Bureau of Meteorology observations with one year of intensive fine-scale temperature monitoring. I found that warming was greatest at inland locations, at lower elevations, away from streams, and at sites exposed to hot, dry northwesterly winds. As species are biased in the geographic and topographic positions they occupied, some species have experienced more warming than others and are at greater threat from climate change. I concluded that it was important to continue developing methods to downscale coarse-grained climate surfaces, and suggest that the accuracy of this process could be improved by using a range of topographic factors.There are many methods for selecting predictors in SDMs, and the competing models often make highly variable predictions. I addressed this uncertainty by comparing the performance of models with and without a given environmental factor. I found that there was relatively strong support for the geology and winter minimum temperature predictors, as well as predictors based on contextual indices, as there was a significant drop in model performance when these predictors were excluded. In contrast, there was less support for summer maximum temperature, as other temperature predictors could combine to produce similar model performance. Model performance varied more between models for different species than between different predictor combinations for the same species. I concluded that it was inappropriate to assess models based on subjective benchmarks, such as an AUC of more than 0.7. A comparison between competing models for the same species gives a better indication of the validity of the model building procedure.The results of this research provide important insights into the benefits and challenges of creating SDMs at the landscape scale (extent of 10–200 km). It is a major challenge to obtain spatially and thematically accurate environmental predictors and biotic data at this scale, and studies should include the collection of data to ensure models are adequate. Landscapes will not have as much environmental variation as coarse-scale models, and this will limit the ability to transfer the models to new study areas. However, there are a number of benefits that justify these studies. Producing accurate temperature surfaces at the landscape scale will result in less pseudoreplication and less predictor colinearity. This will improve the robustness of models. Landscape scale studies also allow modellers to capture fine-scale refugia, and this will improve the accuracy of climate change predictions. Finally, many ecological processes operate at a scale that is too fine to be detected with coarse-scale models. Landscape scale models may be the only alternative to detect these processes. There is no optimal scale for SDMs, however, and a future challenge is to better integrate coarse and fine-scale models to make more ecologically robust predictions.

Abstract:
The link between variations of the wintertime large-scale climatic patterns and thermohaline properties of the Mediterranean Sea was studied using correlation coefficients and the difference of the patterns between positive and negative modes. High NAO index is associated with the higher (lower) water temperature in the western (eastern) basin, less precipitation as well as sea level height; and increase of the net evaporation, northerlies and buoyancy flux particularly over the northern part of the basin. Some differences in the relationship between NAO index and oceanographic conditions in the Mediterranean sub-basins have also been evidenced. More specifically, the sea level in the North Ionian gyre is not influenced by NAO. The temperature in the west Alboran Sea is out of phase with the index in spite of the positive correlation in the western basin. In addition, the warmer water in the eastern coasts of the Sicily during the NAO+ is not related to the surface heat fluxes. NAO doesn’t have a weak impact on the SST of the Adriatic sea although the heat gain is more pronounced during the positive NAO. EA pattern reveals a strong influence on the Western Mediterranean and the negative phase of this index is associated by the stronger winter convection. The influence of MOI is more evidenced in the eastern basin by the lower temperature due to heat loss intensification during the positive MOI.

Abstract:
The geographic variation of taxonomic richness may be directly determined by climate through contemporaneous/ecological processes, versus other (e.g., historical/evolutionary processes) that happen to be collinear with contemporaneous climate. In Chapter 1 I evaluated hypotheses from both groups of explanations in North America. If contemporaneous climate controls patterns of richness, then richness should vary with climate through time in the same way that richness varies with current climate through space. Over the last ca. 11,000 yr, richness-temperature relationships remained reasonably constant. Between 12,000 and 14,000 yr BP, when climate fluctuated rapidly, richness gradients as a function of temperature were significantly shallower. If historical climate over the last 21,000 years determines patterns of richness, then historical climate should be a better predictor of richness than contemporaneous climate. I rejected historical-climate as a better predictor of richness. Contemporaneous climate stands as the most plausible explanation for contemporaneous patterns of richness, at least over the last 11,000 yr. In Chapter two, I tested the prediction that richness of most taxa should increase with temperature in all but the warmest and driest areas. Climate warming during Pleistocene-Holocene transition led richness increases in wet areas, but richness declines in dry regions, as expected from current richness-climate relationships. A decline in small mammal species richness in Northern California since the late Pleistocene was expected from the current richness-climate relationship for this group in North America. These results contest the view that future global warming may lead to species extinction rates that would qualify as the sixth mass extinction in the history of the earth. In chapter three, I first tested the hypothesis that richness gradients mainly reflect the sum of individual species climatic tolerances. I tested this hypothesis for birds, mammals and trees native to eastern North America (ENA, where there are no major barriers to dispersal). The number of species present in any given area in ENA is usually much smaller than the number of species in the continental pool that tolerate the climatic conditions in that area. Second, I tested several explanations for patterns of unfilled potential richness. Unfilled potential richness is inconsistent with postglacial dispersal lags, climatic variability since the Last Glacial Maximum, or with biotic interactions. In contrast, unfilled richness is highly consistent with a probabilistic model of species climate occupancy. Individual species climatic tolerances is not the process generating the main current patterns of richness, nor are post-glacial dispersal lags, climatic variability since the LGM or biotic interactions. This thesis is consistent with the hypothesis that contemporaneous climate directly controls spatial patterns of richness. Generally, there seems to be little need to invoke historical processes as determinants of current gradients of richness.

Abstract This chapter examines the key climatic driving factors for changes in the incidence of Lyme disease and explores how these depend on the level of global warming. It aims to provide some context for the more detailed expert opinions in this book as well as to show how the key climatic driving factors for Lyme disease relate to the Paris targets for climate stabilization. Section 3.1.2 summarizes some of the key findings in the literature concerning the sensitivity of Ixodes life cycles to climate. Section 3.1.3 offers a very brief summary of anthropogenic climate change and climate change projections. Section 3.1.4 tentatively suggests some simple climate thresholds that are broadly consistent with the current global pattern of Lyme disease hotspots. Lastly, Section 3.2 explores the implications for the distribution of Lyme disease under the 2°C limit of the Paris climate agreement.

AbstractThis chapter brings together a range of themes covered within the book thus far. It reflects on the diversity of problems different parts of the world are facing as the impact of climate change gathers pace. These problems encompass more cardiac complications arising from the air pollution generated from climate-triggered fires to the proliferation of vector-borne infectious diseases. In doing so, it discusses the complexity of pathways provoked by climatic change that might increase and even extend the burden of heart disease globally. Concurrently, the prospect of some unexpected benefits (in terms of disease reduction due to climate change) are identified. From that global perspective, some important changes in the ‘infectious threats’ posed to people living in the major continents are presented, noting, once again, how the poorest people in the world will likely bear the brunt of any changes in the pattern of disease provoked by climate change.

Abstract:
AbstractThe hydrogen isotopic signature (δ2H) of water in trees contains information on plant functional responses to climatic changes and on the origin of the water. This is also true for the non-exchangeable hydrogen isotopic signature (δ2HNE) of plant organic matter, which contains additional physiological and biochemical information that can be dated to specific years if extracted from annual rings of trees. Despite this potential for gaining unique insights from δ2HNEof tree-ring cellulose (δ2HTRC), it has not been widely used compared to other isotope signals, likely due to challenging methodological constraints and interpretations of these isotopic signals. In this chapter, we first summarize hydrogen isotope (2H-) fractionation that occurs between source water and tree rings and review methods (e.g. nitration, equilibration, position-specific applications) and calculations to determine δ2HNE in tree material. Building upon a summary of the current state of knowledge, this chapter also provides an exhaustive synthesis of δ2HTRC papers, applications, and associated data from approximately 180 sites across the globe (paired with modelled precipitation δ2H values and climate data). The data allow us to investigate the hydrological-climatic effects driving δ2HTRC pattern on a global scale, the relationship of hydrogen with oxygen isotopes in the same tree-ring material, as well as the influence of physiological-biochemical effects (e.g., species differences, tree growth) that appear to be more important on local or temporal scales than on a large spatial scales. Thus, when local hydro-climatic influences on source water δ2H can be isolated, δ2HTRC gives novel insights on tree physiological responses to abiotic and biotic stresses. We conclude that the growing constellation of tree-ring metrics, including advancements in 2H-processing (i.e., equilibration techniques allowing rapid determinations of δ2HNE) and further refinements to the understanding of post-photosynthetic 2H-fractionations will together provide many new opportunities to understand past climates and ecophysiology by using δ2H in tree rings.

Abstract:
AbstractRainfall-induced landslides are widely occurring phenomena that cause billions of US dollars annually in damage, and thousands of deaths globally. The Philippines, due to its climate, geographic location and topography, is among those countries most prone to the hazard. The strong climatic warming trend over the past decades has affected the rainfall pattern in the country, thus affecting the landslide distribution as well. This study aims to determine how the rainfall in our study area, Davao Oriental, is expected to change in the future in response to climate warming and how such a change may affect the landslide susceptibility pattern in the province. Results show that contrary to the general perception of increased landslide susceptibility due to a warming climate, a decreased susceptibility is anticipated in the study area. Despite this decrease, however, there remains high to very high landslide hazard for the northern part of the province well into the future, and risk reduction work is still needed in this area. Moreover, while the projected decrease in rainfall and landslide susceptibility is a positive sign concerning landslide hazard management, such a drying trend may spawn other hazards, including drought and water shortage, underscoring the need for a multi-hazard assessment that takes into account the complex interrelationships between different hazards. We deem the results of the study to be very important for better prioritization and more efficient allocation of resources for disaster risk management and reduction. The methodology developed for this study can be applied to other parts of the Philippines, and other regions as well.

Abstract:
Consequences of climate change have social, economic and environmental effects. Changes in weather patterns directly impact to transport infrastructures, which play a strategic role in emergency management. Calamitous events as consequence of weather and climatic processes raise the need to foresee adaptation measures to climate change, which is already in place. Although there is a large literature on the effects of climate change, individual and collective responses and behaviours are unclear to such changes. Infrastructures are urban community goods, so adaptation actions concern values and preferences that affect the community itself. In order to measure these values, it is appropriate to consider the impacts (understood as the interpretation of the effects) perceived by communities, but most of the conventional evaluation approaches show obvious limitations. The paper proposes to use inclusive processes, based on the theory of deliberative democracy, in the economic judgments of value and choice in the field of climate change and the adaptation measures related to urban infrastructures. Given the series of effects climate change generates on a single infrastructure and the related adaptation measures, the procedures proposed in this paper enable the members of the community involved to: a) appraise the Shared Economic Value (SEV) of the impact produced by climate change and the related adaptation measures; b) to obtain a Shared Multi-criteria Judgment of alternative adaptation measures.

Abstract:
Rapid urbanization across Lagos, Nigeria has driven extensive land cover modifications with significant climatic impacts. This study analyzed interlinkages between land use land cover (LULC) transformations and land surface temperature (LST) shifts in the intensely developing Lagos suburb of Ikorodu from 1991-2021 utilizing robust geospatial techniques. Multi-spectral Landsat 5, 7 and 8 data enabled reliable LULC classification into five covers using a Random Forest algorithm. Subsetting the Ikorodu area facilitated localized change analyses across 1991, 2001, 2011 and 2021. LULC changes significantly impacted regional microclimates by altering surface energy budgets. Replacing vegetation with constructed materials increased LSTs while diminishing humidity via lower transpiration. Quantifying alteration magnitudes and spatial patterns provided crucial historical perspectives on urban expansion and climatic changes. Over 30 years, built-up area rose from 14% to 65% while vegetation declined from 52% to 9%, with LST increasing from 23.13�C to 27.21�C. Statistical analyses indicated LST strongly, and positively correlated with a Built-Up Index. Cooling prevailed on semi-rural peripheries with more intact vegetation. This research demonstrates and models LULC-LST interlinkages over years of swift development around Lagos, delivering a framework for crafting sustainable growth policies and balancing modernization goals with ecological stability. Explicit urban heat island effect mitigation strategies combining infrastructural adaptations and green space retention are recommended to promote regional climate resilience.

Abstract:
Climate change significantly affects agriculture in Slovakia by altering precipitation patterns, temperatures, and the length of the growing season. Common effects include drought, more intense rainfall, higher summer temperatures, and increased pest populations, all of which influence crop production and livestock breeding. Human activities have already impacted atmospheric properties such as temperature, precipitation, CO2 levels, and ground-level ozone, and this trend is expected to continue. While warmer climates may benefit some crops, the increased frequency of droughts, floods, and heatwaves will challenge growers. In some regions, climate change may make crop cultivation unfeasible. Farmers in Slovakia must adapt to these changes to mitigate negative economic impacts. Adaptation strategies include using climate-resilient crop varieties, improving soil and water management, and adopting innovative agricultural technologies. Expanding crop cultivation into higher elevations is possible but depends on soil suitability. However, the risk of late frosts is a concern, as an extended growing season could lead to early blooming, followed by frost damage. Recognizing and addressing climate change's impact on agriculture is essential for ensuring sustainable production, supporting resilience, and reducing environmental harm.

Abstract:
This report details the climate (temperature, precipitation, drought, and streamflow) of Santa Monica Mountains National Recreation Area (NRA) during 2020. Gridded GIS maps are used to present broad-brush conditions across the region for each month. This regional presentation is compared to detailed data from Remote Automated Weather Stations (RAWS), weather stations in Global Historical Climatology Network (GHCN), and data from USGS stream gages. Prior to analysis, a set of data quality control checks were performed by the authors in accordance with an established National Park Service protocol (Rocky Mountain Climate Working Group 2010). Key points summarizing calendar year 2020 are presented as bullets in the Conclusion section at the end of the report. There was significant spatial and month to month variability in the data that provided exceptions to these generalizations, so an examination of the regional maps is key to understanding the climatic patterns for 2020. Readers can download the data used in this report and make custom climate graphs and tables of their own by visiting www.ClimateAnalyzer.org.
