Abstract:
The two parameters believed to influence habitat utilisation by feral pigs and wild boar (Sus scrofa) are protection from high temperatures and distribution of food. However, whether there is an interaction between these parameters is unknown. To examine the influence of high temperature on habitat utilisation, the use of four rangeland habitats (shrubland, woodland, riverine woodland, and ephemeral swamps) by feral pigs in north-west New South Wales, Australia, was measured by radio-telemetry during and after a drought. In each habitat, protection from high temperature was indexed once by vegetation cover, at three strata, while over the course of the study, food distribution was indexed by estimating pasture biomass in each habitat. Riverine woodland provided the most shelter from high temperature, followed by woodland, shrubland and ephemeral swamps. On average, ephemeral swamps had the highest pasture biomass, followed by riverine woodland, shrubland and woodland. The amount of pasture in each habitat increased after the drought but changed at different rates. During autumn, spring and summer feral pigs preferred riverine woodland but in winter shrubland was preferred. Multivariate regression indicated that habitat utilisation was significantly influenced by pasture biomass in shrubland and mean maximum temperature in the study area. The results suggest that feral pigs are restricted by high temperatures to more shady habitats during hot weather but when the constraint of high temperature is relaxed they distribute themselves more according to the availability of food.

Abstract:
Within the semiarid regions of New South Wales, Australia, the endangered southern bell frog (Litoria raniformis) occupies a landscape that is characterised by unpredictable rainfall and periodic flooding. Limited knowledge of the movement and habitat-occupancy patterns of this species in response to flood events has hampered conservation efforts. We used radio-tracking to assess changes in movement patterns and habitat occupancy of L. raniformis (n = 40) over three different periods (November, January and April/May) that coincided with the flooding, full capacity and subsequent drying of waterbodies within an irrigation landscape. We assessed (1) the use of permanent and ephemeral habitats in response to flooding and drying and (2) distances moved, turning angles and dispersion of frogs during wetland flooding, full capacity and drying. Individuals remained in permanent waterbodies in November but had abandoned these areas in favour of flooded ephemeral waterbodies by January. As the ephemeral waterbodies dried, radio-tracked individuals moved back into permanent waterbodies. The movement patterns of radio-tracked individuals were significantly different in the three radio-tracking periods, but did not differ significantly between sexes. Individuals moved significantly greater distances over 24 h, in straighter lines and movements were more dispersed while they occupied ephemeral waterbodies during January than when they occupied permanent waterbodies during November and April/May. Local weather conditions did not influence movement patterns when all three tracking periods were modelled together using a single linear stepwise regression. The dynamic distribution of habitat patches over space and time, combined with changing patterns of resource utilisation and movement of L. raniformis, highlights the importance of incorporating both permanent and ephemeral habitat patches into conservation plans. Reductions in flood frequency and extent of ephemeral wetlands due to modified flooding regimes have the capacity to limit dispersal of this species, even when permanent waterbodies remain unchanged.

Abstract:
Abstract While ephemeral wetlands contribute significantly to regional freshwater biodiversity, their role in supporting threatened and imperiled species of crayfish is not widely recognized. As the center of global crayfish biodiversity, the southeastern United States (US), and the state of Alabama (AL) in particular, are important focal areas where information is needed to develop understanding of habitat constraints determining the distributions of crayfish species. To this end, we documented crayfish species associated with ephemeral wetlands and associated wetland habitats that have been traditionally under sampled. Fifteen species of crayfish were documented among 96 survey sites. This assemblage included three Alabama state-listed Priority 1 species [Cambarellus diminutus Hobbs, Fallicambarus burrisi Fitzpatrick, Procambarus viaeviridis (Faxon)] and five Priority 2 species [Hobbseus prominens (Hobbs), Orconectes lancifer (Hagan), Procambarus evermanni (Faxon), P. leconti (Hagan), P. marthae Hobbs]. An undescribed species of Cambarellus (“sp. A”) was also documented, and will presumably be eventually designated a Priority 1 species in Alabama due to its restricted distribution and apparent endemism. Ten species of crayfish were documented from ephemeral wetlands, including four Priority 1 and 2 species [Cambarellus sp. A (presumed Priority 1 species), H. prominens, P. marthae, P. viaeviridis]. Most populations of Priority 1 and 2 species we documented are within the 100-year floodplain of the Black Warrior River. Ephemeral wetlands and associated wetland habitats within the floodplains of large rivers thus appear to be vital habitat for threatened and imperiled crayfish in Alabama. Our results suggest that future crayfish surveys should include sampling of these important but often overlooked habitats.

Abstract:
Ephemeral streams are challenging environments for tadpoles; thus, adaptive features that increase the survival of these larvae should be favored by natural selection. In this study, we compared the adaptive growth strategies of Bombina orientalis (the oriental fire-bellied toad) tadpoles from ephemeral streams with those of such tadpoles from non-ephemeral streams. Using a common garden experiment, we tested the interactive effects of location (ephemeral vs. non-ephemeral), food availability, and growing density on larval period, weight at metamorphosis, and cannibalism. We found that tadpoles from ephemeral streams underwent a shorter larval period compared with those from non-ephemeral streams but that this difference was contingent on food availability. The observed faster growth is likely to be an adaptive response because tadpoles in ephemeral streams experience more biotic/abiotic stressors, such as desiccation risk and limited resources, compared with those in non-ephemeral streams, with their earlier metamorphosis potentially resulting in survival benefits. As a trade-off for their faster growth, tadpoles from ephemeral streams generally had a lower body weight at metamorphosis compared with those from non-ephemeral streams. We also found lower cannibalism rates among tadpoles from ephemeral streams, which can be attributed to the indirect fitness costs of cannibalizing their kin. Our study demonstrates how ephemeral habitats have affected the evolutionary change in cannibalistic behaviors in anurans and provides additional evidence that natural selection has mediated the evolution of growth strategies of tadpoles in ephemeral streams.

Abstract:
This paper aims to highlight the new research and significant advances in our understanding of links between coastal habitat quality/quantity/diversity and the diversity of fisheries species and other mobile aquatic species (hereafter nekton) that use them within coastal landscapes. This topic is quite diverse owing to the myriad of habitat types found in coastal marine waters and the variety of life history strategies fisheries species and nekton use in these environments. Thus, we focus our review on five selective but relevant topics, habitat templates, essential fish habitat, habitat mosaics/habitat connectivity, transitory/ephemeral habitat, and the emerging/maturing approaches to the study of fish-habitat systems as a roadmap to its development. We have highlighted selected important contributions in the progress made on each topic to better identify and quantify landscape scale interactions between living biota and structured habitats set within a dynamic landscape.

Abstract:
Low altitude granitic hillock systems prevalent in Palghat (Palakkad) Gap region of southern Western Ghats were analyzed for seasonal dynamics in wetland taxa associated with marshy ephemeral flush vegetation, small ephemeral pools and deep rock pools. Due to characteristic habitat features, such systems harbor a unique pattern of microhabitats and associated floristic components. Wet phase in rocky outcrops in the monsoon season establishes a hydro-geomorphic habitat that supports establishment of wetland taxa like Eriocaulon, Drosera, Utricularia, Dopatrium, and Rotala. Seasonal shift in the floral associations was evident in tune with wetland dynamics. Wet rocks support ephemeral flush vegetation which display some unique plant associations of species of Eriocaulon, Utricularia, Drosera, Cyanotis, Murdannia, and Lindernia. Small ephemeral pools displayed taxa like Rotala malampuzhensis R.V. Nair, Dopatrium junceum (Roxb.) Buch.-Ham. ex Benth., D. nudicaule (Willd.) Benth., Monochoria vaginalis (Burm.f.) C. Presl, and Cyperus iria L. Rocky pools are the habitats of aquatic angiosperms like Nymphaea nouchali Burm. f., Ludwigia adscendens (L.) H. Hara, Utricularia aurea Lour. and Hydrilla verticillata (L.f.) Royle. The study documented 121 plant taxa from 37 families during a wet phase from rocky outcrops of the study area. Gradual shift in vegetation is evident as water recedes from granitic hillocks. During the period from December to March, the rocky pools dry up which results in a shift in the vegetation pattern where Poaceae members form the dominant elements. As most of the rocky outcrops are exposed to extreme temperature and acute water shortage, the taxa inhabiting such ecosystems tend to evolve much faster than in other habitats. Moreover, the vicinity of these hillocks in the Palghat Gap region to human settlements, face threats like fire, grazing, quarrying, dumping of wastes etc. which may cause considerable loss to the very sensitive plant communities which are not yet fully documented.

Abstract:
Abstract We examined effects of movement patterns and habitat use of female Wood Ducks (Aix sponsa) during incubation on incubation constancy and recess frequency. Incubating females (n = 41) were equipped with subcutaneous radiotransmitters and subsequently located during daily recess events. Using compositional analysis, we determined beaver ponds, creeks, ephemeral wetlands, and lake-influenced habitats ranked higher in preference than other available aquatic habitats (i.e. managed impoundments, farm pond, and lake habitats). An inverse relationship between female use of the top four ranked habitats and recess range size suggested that those were high-quality habitats. Mean (±SE) incubation constancy (n = 40 nests) was 81.3 ± 0.8%, and females took an average of 2.2 ± 0.3 recesses day−1. Incubation period averaged 31.8 ± 0.3 days, and there was a weak inverse relationship between incubation period and incubation constancy. Incubating females lost 3.9 ± 0.8% of early incubation body mass, but body-mass changes were not associated with use of preferred habitats (i.e. beaver ponds, creeks, ephemeral wetlands, and lake-influenced areas). Initiation date of incubation and percentage use of preferred habitats were the most important variables describing variation in incubation constancy. Constancy declined later in the breeding season and with increased use of preferred habitats. Recess frequency decreased with increasing variation in distances that females traveled from the nest. Wood Ducks nesting at southern latitudes generally are not energetically constrained during incubation, and nest attentiveness is only weakly associated with incubation period. We would expect stronger relationships between habitat use, body-mass dynamics, and incubation behavior under environmental conditions that are more severe or less predictable.

Rinne, Debra. "TESTING THE PENINSULA EFFECT: DOES IT AFFECT FRESHWATER CRUSTACEANS INHABITING EPHEMERAL WETLANDS ON FLORIDA'S RIDGES?" Master's thesis, University of Central Florida, 2006. http://digital.library.ucf.edu/cdm/ref/collection/ETD/id/3610.

Full text
Abstract:
The peninsula effect is a pattern of diversity wherein species richness decreases along a peninsula from base to tip and is attributed to three mechanisms: historical processes, habitat gradients, and immigration-extinction equilibrium. Numerous studies have reported conflicting results involving the existence, cause, and validity of the peninsula effect in part because they did not account for effects of history or habitat on species richness patterns and because most previous research focused on organisms that actively disperse, which could confound results with behavioral habitat selection. Florida poses an excellent opportunity to study the peninsula effect because of its geological history and its unique ridges have similar histories (e.g. age, elevation, and sediment). Habitat changes down the peninsula, from a warm temperate climate in the north to a subtropical climate in the south. I studied freshwater crustaceans in isolated wetlands because crustaceans are diverse and disperse passively among these discrete habitats. My study design and statistical analyses controlled for two of the three mechanisms (habitat and history) that may generate a peninsula effect to better test for the third hypothesis (immigration-extinction equilibrium) on the Florida peninsula. Thirty-one wetlands were sampled for crustaceans monthly from November 2004 through April 2005, or until a site dried. Human disturbance was minimized by choosing isolated, ephemeral wetlands located within state reserves, parks, and forests located on four major ridges: Trail, Brooksville, Mount Dora and Lake Wales. I measured several environmental variables to assess habitat variation among sites. Limnological parameters included temperature, pH, dissolved oxygen, conductivity, chlorophyll &aacute;, pheophytin, total nitrogen, total phosphorus, and total hardness. Other habitat variables included surface area, distance to nearest water body, fish presence or absence, hydroperiod, total transmitted light and canopy openness. Crustacean species were identified to the lowest practical taxonomic level (typically species) and recorded as present or absent. A total of 53 different crustaceans were identified, including 41 cladocerans, 10 copepods, and 2 ostracods. In a multiple regression, environmental variables and sampling effort accounted for 57% of the variation in species richness. Regression of remaining variation (residuals) against latitude, which measures position along the peninsula, was not statistically significant. The same pattern was obtained when the sequence of regressions was reversed. Therefore, the peninsula effect does affect the species richness of freshwater crustaceans inhabiting ephemeral wetlands on Florida's ridges. Instead, variation in species richness was determined mainly by habitat differences, particularly the complex interaction of phosphorus levels, isolation, fish presence or absence, and hydroperiod. This study may serve as a model for more thorough analyses of mechanisms (history, habitat, and immigration-extinction) of a peninsula effect in other taxa.<br>M.S.<br>Department of Biology<br>Arts and Sciences<br>Biology

Abstract:
Comprendre comment les pratiques agricoles affectent l’assemblage des communautés de plantes adventices dans les parcelles de grandes cultures annuelles est un enjeu majeur en agro-écologie. Les plantes adventices sont supposées partager certaines caractéristiques écologiques qui leur permettent de se maintenir dans les parcelles cultivées malgré les contraintes environnementales exercées par les pratiques agricoles. De plus, l'assemblage des communautés adventices est supposé dépendre d'interactions entre des processus écologiques opérant pendant une année de culture (par exemple : filtre abiotique) et à l'échelle de la succession des années de cultures (par exemple : dispersion temporelle). Les travaux présentés dans cette thèse ont pour but de tester ces deux hypothèses.Premièrement, nous avons comparé les pools d’espèces adventices aux plantes non adventices retrouvés dans les milieux ouverts et non cultivés sur la base de traits fonctionnels pour identifier les caractéristiques écologiques propres aux adventices. Les résultats montrent que les plantes adventices représentent un sous-échantillon des plantes retrouvées plus largement dans les milieux ouverts principalement filtré par les perturbations type travail du sol. Deuxièmement, j'ai proposé des dynamiques de type méta-communautés temporelles pour prédire les patrons de diversité attendus en fonction de l'influence de la dispersion temporelle et des variations temporelles des conditions environnementales sur l'assemblage des communautés. J'ai ensuite testé ces prédictions et quantifié la contribution relative des processus écologiques contemporains et passés sur l’assemblage d’une communauté. Pour ce faire, j'ai utilisé le jeu de données Biovigilance flore qui est un suivi sur une décennie des communautés de plantes adventices observées dans 1400 parcelles cultivées. Mes résultats montrent que l’assemblage d’une communauté de plantes adventices dépend d'interactions entre la dispersion temporelle et les conditions environnementales contemporaines de ladite communauté. De plus, mes travaux suggèrent que les risques d’extinctions des espèces adventices augmentent pour des niveaux de variations temporelles des conditions environnementales forts. Analyser directement la composition des banques de graines adventices me permettrait de valider cette hypothèse. Finalement, mes résultats confirment que l’assemblage des communautés adventices est largement imprévisible. Je propose donc un scénario basé sur la théorie des dynamiques de patches et du priority effect pour expliquer ce phénomène.En conclusion, les travaux présentés dans ce manuscrit nous permettent de mieux comprendre comment les pratiques agricoles interagissent avec des processus écologiques à différentes échelles spatiales et temporelles pour façonner les communautés de plantes adventices<br>Understanding how farming practices affect weed community assembly in arable fields is a core challenge of agro-ecology. Weeds are supposed to share particular ecological characteristics that allow them to colonize arable fields despite environmental constrains exert by farming practices. In addition, interactions between ecological processes operating during a cropping season (eg: abiotic filtering) and at the scale of crop succession (eg: temporal dispersal) are supposed to drive weed community assembly in arable fields. These two hypotheses have been tested in my phD work.First, we compared a pool of weed species to a pool of non-weed herbaceous plants based on several functional traits to identify which functional traits and which strategies best characterized weeds. Our result brought evidences that weeds are a subset of non-weed herbaceous plant principally filtered out in arable fields by disturbances such as tillage. Second, I proposed different expected diversity patterns according to the influence of temporal dispersal and temporal variation of environmental conditions within temporal meta-community dynamics. Then I tested these predictions and quantified the respective contribution of contemporary and past ecological processes on weed community assembly. To do so, I used long term weed monitoring Biovigilance Flore dataset. Results showed that weed community assembly relies on complex interactions between temporal dispersal and contemporary environmental conditions. In addition, weed extinction risk seemed to increase for strong temporal variation of environmental conditions. However weed seed bank analyses are needed to confirm this hypothesis. Finally, my results confirmed that weed community assembly is largely unpredictable. I propose that patch dynamics and priority effects may explain this phenomenon.To conclude, the work presented here shade new lights on how farming practices interact with ecological processes across temporal and spatial scales to drive weed community assembly in arable fields

Abstract:
Triops cancriformis (Crustacea: Notostraca) occurs in ephemeral habitats like rain pools or floodplain pools distributed over a large geographical range. The named habitats are disturbed by human impacts and, consequently, T. cancriformis is endangered throughout its distribution range. In the present thesis the populated habitats and threats are characterised and further morphological and genetic variations detected among and within European populations are reported. On the basis of recent investigations it is shown that T. cancriformis subspecies separation is hampered by an individual variability which points to the necessity of species revision. The analysis of mitochondrial gene sequence data suggests that the species has colonised most of Europe very recently. The advantage of a complex reproductive strategy in T. cancriformis in this process is discussed. The population structure resolved with nuclear DNA markers highlights that there is low allelic diversity among and within populations compared to other Branchiopoda (Daphnia). By means of the present study it can be shown that habitat conservation is most important to protect T. cancriformis.

Full text
Abstract:
Community structure in backswimmers (Hemiptera: Notonectide), was investigated via extensive sampling throughout southern Arizona, USA, and Sonora, Mexico, from 1980 through 1985. Co-occurrence and relative abundance data were collected in more than 65 ponds, and in 177 rock basin pools (tinajas) in 21 canyons in the Southwest. Eleven species were collected in Arizona and Sonora, and were divided into two groups, species found in ponds and species found in tinajas. Only two species occurred significantly in both habitats. Tinaja species are largely Southwst endemics, and pond species are widespread or tropical in distribution. Data from artificial habitats suggest that the tinaja species use relatively high topographic relief, and pond species use relatively large surface area as cues to find their respective habitats. Two body size patterns are consistent with a competition explanation of local community structure. The body sizes of co-occurring species are relatively evenly distributed among species occurring in pond and tinaja habitats, and species of similar body size tend not to co-occur (body size ratio <1.3). For example, Notonecta kirbyi and N. lobata only co-occur in tinajas at intermediate elevations; lobata is absent at high elevations and kirbyi is absent at lower elevations. N. indica occurs in ponds at lower elevations and N. unifasciata occurs at higher elevations. Buenoa hungerfordi and B. arizonis both occur in tinajas, but not at the same time of year. Predation was shown experimentally not to be important in producing the body size pattern. Notonecta spp. preyed heavily on the smaller of two Buenoa species presented, an effect that would act to reduce the community-wide body size ratio. Because notonectid communities have larger body size ratios than expected by chance, predation would seem not to be involved in producing this pattern. However, predation does appear to reinforce microhabitat partitioning between the two genera in that Buenoa occupy deeper portions of the water column in the presence of Notonecta than in their absence. This further displaces coexisting individuals of the two genera in space, and reduces overlap in foraging for aquatic insect prey and promotes coexistence.

Abstract:
Identifying amphibian habitats within a landscape provides a tool for managing their populations. I identified if and how amphibians used small ephemeral wetlands (≤ 0.1ha) and streams within the mixedwood forest area managed by Daishowa Marubeni International Ltd. near Peace River, north-western Alberta. Twenty-seven wetlands and their riparian zones were sampled for all life stages of amphibians in 2008 using timed visual encounter surveys. The riparian zones of 11 small streams were sampled with pitfall traps within 120 m of their beds from 2006 to 2008. Habitat features were also measured. Lithobates sylvaticus, Anaxyrus boreas and Pseudacris maculata used small ephemeral wetlands and the riparian zones of ephemeral, intermittent and permanent streams at different life stages. Water temperature and canopy cover influenced amphibian presence and abundance in wetlands. Coniferous and deciduous tree density were associated with L. sylvaticus abundance at the stream sites. I conclude that small waterbodies are amphibian habitats in the mixedwood forest of boreal Alberta.<br>Ecology

Full text
Abstract:
The mechanisms of dung inhabiting insects' heterotrophic succession were studied by preventing the colonisation of early successional insect. The early successional insect, predominantly the large larvae of Calyptratae Diptera, both facilitated and inhibited the later establishing insect. Whereas the removal of early successional species affected negatively the late successional Coleoptera (facilitation), the small late successional larvae of Acalyptratae Diptera were affected positively (inhibition). The patterns retrieved from the heterotrophic succession strongly resemble the patterns retrieved from the autotrophic, mostly plant, succession Therefore it is possible to suggest, that similar mechanisms are behind both the autotrophic and the heterotrophic succession.

Abstract:
This thesis describes invertebrate community on cadavers of small mammals, in particulat how cadaver size influences abundace, density, species richness and composition of the necrobiont community. Cadaver size preference of present insects is also described. Field experiments were performed in 2014 in meadow habitats in spring, summer and autumn season. Cadavers were chosen in three weight groups: mice (20 g), small rats (100 g) and large rats (400 - 500 g). Invertebrate abundance increases with cadaver mass, density of the community remains constant. Larger cadavers also have higher species richness. Most dominant ecological guild are necrophages, represented mosty by blow flies (Calliphoridae). Cadaver size preference of recorded insects differ, necrophagous and predatory taxa tend to prefer larger cadavers. Omnivorous carrion beetles (Silphidae: Nicrophorus) prefer small cadavers. Sex of the carrion beetles (Silphidae) does not affect their cadaver size preference, males and females of particular species have very similar preferences.

Abstract:
Carnivorous Nepenthes pitcher plants contain aquatic ecosystems within each fluid-filled pitcher. Communities of arthropods and microbes colonize pitcher pools, and some organisms are endemic to the pitcher habitat. Flies and mites are the most apparent colonizers, and together with numerous protists, fungi, and bacteria, they form a food web of predators, decomposers, and primary producers. Bacterial diversity and composition are correlated strongly with fluid pH. Closely related organisms co-occur within pitchers, suggesting that competition is not the primary structuring force of pitcher communities. Pitchers are ephemeral habitats when compared with surrounding soil, and the former communities have fewer organisms and are less predictable than the latter. It is still unknown to what extent pitcher plants and their inhabitants influence one another’s fitness.

Abstract:
The latter half of the nineteenth century witnessed a mass media revolution in the widespread explosion of print; this book shows how the habits of consuming printed ephemera are still with us, even as pixels supersede paper. Trivial, disposable printed items, from temperance medals and cigarette cards to cartoons and even novels tell us much about nineteenth-century mediated experience, and our own. For a fresh perspective on media consumption, the book examines affect, a dynamic quality of human mind and body that links emotion to cognition, self to other, and self to environment. Affect shows how mass-mediated material began to dwell in the mind – less so the rational mind of egoistic cognition, than the embodied mind of daydreaming, reverie, and feeling. In such fugitive spaces, the sovereign individual gives way to community and inter-subjectivity as he or she recreates the social body. The book makes visible an array of positions, habitable by people of different classes, genders, ages, and sexualities, such as the mass live audience member, the enchanted viewer, the information “addict,” the self-fashioner, the collector, and the re-player of experience. These positions characterize an earlier moment in a genealogy of media consumption that endures today. The book describes them by putting disposable print forms into conversation with performance, visual culture, literary fantasy, and media theories. Demonstrating the recursive relations between affects and mass media, it reveals the cultural and psychological contours of ephemeral experience.

Abstract:
Through archaeological and archival research from sites associated with the 1893 World’s Columbian Exposition in Chicago, Disposing of Modernity explores the changing world of urban America at the turn of the twentieth century. Featuring excavations of trash deposited during the fair, Rebecca Graff’s first-of-its kind study reveals changing consumer patterns, notions of domesticity and progress, and anxieties about the modernization of society. Graff examines artifacts, architecture, and written records from the 1893 fair’s Ohio Building, which was used as a clubhouse for fairgoers in Jackson Park, and the Charnley-Persky House, an aesthetically modern city residence designed by Louis Sullivan and Frank Lloyd Wright. Many of the items she uncovers were products that first debuted at world’s fairs, and materials such as mineral water bottles, cheese containers, dentures, and dinnerware illustrate how fairs created markets for new goods and influenced consumer practices. Graff discusses how the fair’s ephemeral nature gave it transformative power in Chicago society, and she connects its accompanying “conspicuous disposal” habits to today’s waste disposal regimes. Reflecting on the planning of the Obama Presidential Center at the site of the Chicago World’s Fair, she draws attention to the ways the historical trends documented here continue in the present.

Abstract:
AbstractUrban green infrastructure could represent an important mean for environmental mitigation, if designed according to the principles of restoration ecology. Moreover, if suitably executed, managed and sized, they may be assimilated to meta-populations of natural habitats, deserving to be included in the biodiversity monitoring networks. In this chapter, we combined automatised and expert opinion-based procedures in order to select the vascular plant assemblages to populate different microhabitats (differing in terms of light and moisture) co-occurring on an existing green roof in Zurich (Switzerland). Our results lead to identify three main plant species groups, which prove to be the most suitable for the target roof. These guilds belong to mesoxeric perennial grasslands (Festuco-Brometea), nitrophilous ephemeral communities (Stellarietea mediae) and drought-tolerant pioneer species linked to nutrient-poor soils (Koelerio-Corynephoretea). Some ruderal and stress-tolerant species referred to the class Artemisietea vulgaris appear to fit well with local roof characteristics, too. Inspired by plant sociology, this method also considers conservation issues, analysing whether the plants selected through our procedure were characteristic of habitats of conservation interest according to Swiss and European laws and directives. Selecting plant species with different life cycles and life traits may lead to higher plant species richness, which in turn may improve the functional complexity and the ecosystem services provided by green roofs and green infrastructure in general.

Abstract:
The study of metapopulation dynamics has had a profound impact on our understanding of how species relate to their habitats. A natural, if naïve, set of assumptions would be that species are to be found wherever there is suitable habitat that they can get to; that species will rarely, if ever, be found in unsuitable habitat; that they will be most abundant in their preferred habitat; that species can be preserved as long as a good-size chunk of suitable habitat is conserved for them; and that destruction of a species’ habitat is always detrimental for its abundance. We will see that none of these reasonable-sounding assumptions is necessarily true. Metapopulation biology is a vast field, so to focus this chapter I will be guided partly by questions relevant to conservation biology. There are two important kinds of metapopulation. The so-called Levins metapopulation idea (Levins, 1970) is illustrated in Figure 4.1. It is imagined that patches of habitat suitable for a species are distributed across a landscape. Over time, there is a dynamical process of colonization and extinction: the colonization of empty patches by occupied patches sending out colonizing propagules and the extinction of local populations on occupied patches. This extinction can occur for a number of reasons. Small populations are prone to extinction just by the chance vagaries of the environment, reproduction, and death—environmental and demographic stochasticity (May, 1974b; Lande et al., 2003). An example of a species for which this is important is the Glanville fritillary butterfly (Melitaea cinxia), which has been extensively studied by Hanski and colleagues (Hanski, 1999). This Scandinavian butterfly lives in dry meadows which are small and patchily distributed. Another reason for local population extinction is that the habitat patch itself may be ephemeral. For example, wood-rotting fungi will find that their patch ultimately rots completely away (Siitonen et al., 2005) and epiphytic mosses will ultimately find that their tree falls over (Snall et al., 2005). The second type of metapopulation consists of local populations connected by dispersal, but without the extinction of the local populations.

Abstract:
Most lakes are geologically ephemeral; even the longest-lived individual lakes persist only for tens of millions of years. However there is a continuity to lake systems that transcends the geologically short history of individual lake basins. This continuity comes from the long-term biological evolution of life in freshwater, and fittingly, forms the final subject of this treatment of paleolimnology. Like the oceans, lakes have provided habitats for living organisms for most of the earth’s history. Yet the patterns of aquatic ecosystem evolution in rivers and lakes have differed dramatically from those of the oceans. In large part this can be traced to the fundamentally ephemeral nature of most continental aquatic habitats and the ‘‘disconnectedness’’ in both time and space that exists between individual lakes and rivers compared with the world ocean. This pattern of temporal and spatial patchiness in water body distribution on the continents has shaped the evolution of lacustrine species and communities. Some understanding of this history can be gleaned from the study of modern ecology and molecular genetics of living freshwater organisms. But to understand long-term trends in lacustrine biodiversity and their relationship to the history of the lacustrine environment we must turn to the pre- Quaternary fossil record. Understanding this history, the timing and tempo of major species diversification and extinction events, and the evolution of key ecological innovations is critical for correctly interpreting ancient lake deposits. The fossil record of pre-Quaternary lakes is more difficult to interpret than that of more recent lake basins. Robust phylogenies are largely unavailable for clades of ancient lacustrine fossils, hindering our ability to test hypotheses of evolutionary ecology, although that situation hopefully will improve in coming years. Many major clades of fossil lacustrine organisms are extinct, and ecologies must be inferred from their depositional context. Even for organisms that have close-living relatives, our certainty in making inferences about habitat and relationship with other species weakens as we go back in time. Also the record we have to work with deteriorates with age, the result of (a) a declining volume of lake beds available for study with increasing age, (b) difficulties associated with processing lithified lake beds for their fossil content, and (c) an increasing likelihood of destruction by diagenesis with increasing age.

Abstract:
Crustacea in standing waters are a diverse taxonomic assemblage with representatives in all available habitats from the benthic zone to the pelagial in larger water bodies. While most higher taxa are widespread and occasionally cosmopolitan, this is only partially true at the genus and species level. The crustacean fauna of geologically young lakes, or ponds, is characterized by widespread species that are not even necessarily restricted to lentic habitats. These species generally have good to excellent dispersal capabilities, especially those dwelling in ephemeral habitats. Small groups such as branchiopods and copepods dominate under these conditions among obligate still-water dwellers. In contrast, endemism and occasional striking adaptations are the hallmarks of crustacean species flocks, especially in the radiations of amphipods, decapods, and ostracods in the fewer than 10 ancient lakes worldwide. These radiations have arisen in situ through the diversification of unspecialized ancestors. All comparatively well-studied radiations for which molecular phylogenetic, taxonomic, and ecological data are available show particular adaptations of trophic morphology correlated to specific habitats. Prime examples are the species flocks of amphipods in Lake Baikal and of atyid shrimps in Lake Tanganyika and in two Indonesian lakes. These groups have most likely evolved through adaptive radiation. A major challenge for research on crustaceans in ancient lakes, and in standing waters generally outside Europe and North America, is the lack of basic data from species diversity to genetics for many, if not most, taxa. Getting a grip on species diversity, distributions, ecology, and, at a different level, genomics will be a research priority for coming decades.

Abstract:
Human impacts on freshwater and marine ecosystems have long been of special concern due to water’s essential role in ecosystem functioning and human civilization. Urban development causes a large number of changes in all types of aquatic environments, from small ephemeral pools to rivers to great lakes to expansive coastal habitats. These changes can strongly influence evolution of life in the water by altering selection, gene flow, and genetic drift. Yet our understanding of the evolutionary consequences of urbanization on aquatic organisms is still in early stages. This chapter reviews the impacts of urbanization on aquatic taxa, examining the evolutionary consequences (known or likely) of four major types of urban-induced changes to ecosystems: biotic interactions, physical environment, temperature, and pollution. By drawing connections between literature on ecological and evolutionary impacts in aquatic urban environments, the chapter concludes that (1) several anthropogenic factors seem to commonly drive evolutionary and phenotypic change (organic-compound pollution, altered temperature, and hydrologic shifts), (2) predictability of evolutionary changes are often taxa specific, and may commonly depend on the focal ‘scale’ (e.g., whole-organism performance, morphology, or gene), and (3) there are a few key ‘frontier topics’ (altered biotic interactions, artificial light, sound pollution, and fragmentation) where additional research on phenotypic evolution would be particularly informative.

"The lake trapping was continued twice monthly from February 1991, two years after the first filling of the stage 2A reservoir, until June 1993. The trapping locality at Toonpan was essentially the same as for the 1984–85 studies except that for Big Bay was moved a few hundred metres up the incline. Because the expansion from stage 1 to 2A involved extensive clearing of marginal scrub, grassland and forest, almost total control of five mosquito species utilizing tree holes and plant axils (Aedes alboscutellaris, Aedes mallochi, Aedes purpureus, Aedes quasirubithorax) or shaded pools (Uranotaenia nivipes) occurred. The transformation of temporary wetland with ti-trees (Melaleuca spp.), lilies (Nymphoides indica, Nymphaea gigantea) and submerged plants into an unvegetated muddy foreshore similarly reduced Mansonia spp. and Coquillettidia crassipes, whose larvae depend on attachment to arenchymatous or lacunate macrophytes. Larvae of these genera have pointed reinforced tips to their siphons which are used to pierce these plants to breathe. Because of the devastating nature of the inundation and the time required for new breeding habitat to re-establish, mosquito populations increased through to the end of 1993 but the mean abundance of adult Culex annulirostris had not changed significantly from stage 1 levels. The trend for this species and for Anopheles annulipes was upward, and one can only speculate on population levels when the marginal vegetation has fully established. Due to the extensive loss of marginal vegetation and the creation of expanses of shallow muddy pools, especially towards Toonpan, Anopheles amictus and Aedes normanensis populations increased by 36-fold and 282-fold, respectively (Figure 9.2). The ramifications of this are interesting as Aedes normanensis is well recognized as a vector of Ross River virus and Murray Valley encephalitis, especially inland where Anopheles amictus (probably another species complex) has been the source of Ross River, Barmah Forest and Edge Hill viruses. Control of mosquitoes is usually directed at removal of breeding habitat (source reduction) or aimed at larvae which often aggregate in large numbers in discrete sites. Aedes normanensis is ephemeral and its desiccation-resistant eggs characteristically hatch in response to wet season rainfall filling up temporary pools. Plague numbers appear one month and may be gone the next. More accurate definition of these breeding sites, particularly at Toonpan, Antill Creek and Ross River, is required before control options can be considered. As already mentioned, the clearing process created vast expanses of bare muddy pools, particularly at the north-eastern end (e.g. Toonpan). As the lake gradually receded during the dry season, ideal breeding sites were created and populations increased through spring (from September) and also in the late wet season (March to April) when dry sites were refilled by rainfall. Thus, although the land clearing had benefits in eliminating tropical itch mites and some minor mosquito species, it probably paved the way for population growth of Aedes normanensis and Anopheles amictus. This could possibly be considered a dubious swap, although time will tell. Little is known of their biology and their flight range, the latter being of obvious importance to recreational activity at the other end of the lake. Fortunately, however, they are mainly active at night." In Water Resources. CRC Press, 1998. http://dx.doi.org/10.4324/9780203027851-32.
