Abstract:
Previous studies have shown that climate change has significant cumulative effects on vegetation growth. However, there remains a gap in understanding the characteristics of cumulative climatic effects on different vegetation types and the underlying driving mechanisms. In this study, using the normalized difference vegetation index data from 1982 to 2015, along with accumulated temperature, precipitation, and solar radiation data, we quantitatively investigated the intra-annual cumulative effects of climatic factors on global vegetation biomes across climatic zones. We also explored the under

Abstract:
Vegetation is vital, and its greening depends on access to water. Thus, precipitation has a considerable influence on the health and condition of vegetation and its amount and timing depend on the climatic zone. Therefore, it is extremely important to monitor the state of vegetation according to the movements of precipitation in climatic zones. Although a lot of research has been conducted, most of it has not paid much attention to climatic zones in the study of plant health and precipitation. Thus, this paper aims to study the plant health in five African climatic zones. The linear regression

Abstract:
This work evaluated the ability of UAVs to detect field heterogeneity and their influences on vineyard development in Yepes (Spain). Under deficit irrigation, vine growth and yield variability are influenced by soil characteristics such as water holding capacity (WHC). Over two irrigation seasons (2021–2022), several vegetation indices (VIs) and parameters of vegetative growth and yield were evaluated in two field zones. Multispectral and thermal information was obtained from bare soils. The water availability showed annual differences; it was reduced by 49% in 2022 compared to 2021, suggestin

Palynological analysis of sediments from Lake El'gygytgyn, formed during oxygen-isotope stages 50-59, documents the changes of cold stages, interstades and interglaciations. Ten pollen zones were identified and correspond to the interval 1.4920-1.6975 million years ago. This interval includes the Gilsa magnetic event (1.68 Ma), which is an important chronological landmark. Larix pollen appears in the palynological spectra of all stages. The presence of this taxon during warm climates indicates that larch forests established in the areas of the Anadyr Plateau and Lake El'gygytgyn and replaced t

Kosovo, located at the intersection of continental, alpine and sub-Mediterranean climatic influences, represents a biogeographical transition zone with high ecological complexity. In this study, three different biogeographical regions are delineated - the continental, the alpine and the sub-Mediterranean region - using an integrative approach combining vegetation, climate and topography. By using updated vegetation mapping, standardized environmental data and K-means clustering, the study shows the spatial organization of vegetation alliances along altitudinal and climatic gradients.

The response of plants to climate change has become a topical issue. However, there is no consensus on the synergistic processes of the canopy and trunk growth within different vegetation types, or on the consistency of the response of the canopy and trunk to climate change.

Abstract. Vegetation provides key ecosystem services and is an important component in the hydrological cycle. Traditionally, the global distribution of vegetation is explained through climatic water availability. Locally, however, groundwater can aid growth by providing an extra water source (e.g. oases) or hinder growth by presenting a barrier to root expansion (e.g. swamps). In this study we analyse the global correlation between humidity (expressing climate-driven water and energy availability), groundwater and forest growth, approximated by the fraction of absorbed photosynthetically activ

Vegetation spatial structure of the Kurile Islands is conditioned by complex interactions of endogenous and exogenous factors. Meridional extension for almost 1200 km determines a significant climatic differenciation within archipelago. It is resulted in changes of vertical vegetation zones in the different regions of Kurile Islands. System of hot and cold currents in the adjacent sea water is the factor of asymmetry of vegetation.

The Köppen classification of climate integrates precipitation and temperature information with natural vegetation patterns to create a precise representation of any particular region's climate. This integration depends on the empirical relationship of climate and vegetation, which indicates that distinct locations in the same class have similar vegetation attributes.

Vegetation is a vital component of ecosystems and an indicator of global environmental change. It is significantly influenced by climate factors.

Nevertheless, ideal management practices of roadside vegetation have not yet been established partly due to insufficient knowledge of the ecological strategies of plants invading roadsides, especially curbside c

Climatic effects on aquatic environments are an important factor in the ecology of ostracodes judging from their biogeography especially with respect to moisture balance and ecoregions (vegetation zones). The importance of climate in controlling ostracode distribution is underscored by major ecological changes indicated by co-stratigraphic changes in ostracode and pollen biozones throughout the Quaternary. Climatic interpretation of ostracode records are complicated, however, by several non-climatic factors, including basin shoaling, changes in water chemistry due to abrupt changes in the flux
