Abstract Understanding environmental effects on the distribution and abundance of species is central to ecology, biogeography evolutionary biology. This led development models (SDMs) that relate spatial variation in occurrence variables. So far, SDMs rarely considered habitat structure, as a major determinant bird distributions. While remote sensing increasingly provides high-resolution measure...
The effects of Quaternary climatic oscillations on the demography of organisms vary across regions and continents. In taxa distributed in Europe and North America, several paradigms regarding the distribution of refugia have been identified. By contrast, less is known about the processes that shaped the species' spatial genetic structure in areas such as the Himalayas, which is considered a bio...
BACKGROUND The temperature in arid Eastern Central Asia is projected to increase in the future, accompanied by increased variability of precipitation. To investigate the impacts of climate change on plant species in this area, we selected two widespread species as candidates, Clematis sibirica and C. songorica, from montane coniferous forest and arid steppe habitats respectively. METHODOLOGY/...
Four North American trees are becoming invasive species in Western Europe: Acer negundo, Prunus serotina, Quercus rubra, and Robinia pseudoacacia. However, their present and future potential risks of invasion have not been yet evaluated. Here, we assess niche shifts between the native and invasive ranges and the potential invasion risk of these four trees in Western Europe. We estimated niche c...
To conserve a declining species we first need to diagnose the causes of decline. This is one of the most challenging tasks faced by conservation practitioners. In this study, we used temporally explicit species distribution models (SDMs) to test whether shifting weather can explain the recent decline of a marsupial carnivore, the eastern quoll (Dasyurus viverrinus). We developed an SDM using we...
The central role of species competition in shaping community structure in ecosystems is well appreciated amongst ecologists. However species competition is a consistently missing variable in Species Distribution Modelling (SDM). This study presents results of our attempt to incorporate species competition in SDMs. We used a suit of predictor variables including Soil Adjusted Vegetation Index (S...
Aim As climate change presents a major threat to biodiversity in the next decades, it is critical assess its impact on species habitat suitability inform conservation. Species distribution models (SDMs) are widely used tool impacts species’ geographical distributions. name of these suggests, level most commonly taxonomic unit SDMs. However, recently has been demonstrated that SDMs considering r...
Recent studies suggest that species distribution models (SDMs) based on fine-scale climate data may provide markedly different estimates of climate-change impacts than coarse-scale models. However, these studies disagree in their conclusions of how scale influences projected species distributions. In rugged terrain, coarse-scale climate grids may not capture topographically controlled climate v...
Species distribution models (SDM) have been proposed as valuable first screening tools for predicting species responses to new environmental conditions. SDMs are usually conducted at the level, assuming that species-environment relationships a species-specific feature do not evolve and show no variability across species’ range. However, broad tolerances level can encompass narrower different sp...
Mapping the distribution of allergenic plants in urbanized landscapes is high importance to evaluate its impact on human health. However, data not always available for allergy-relevant species such as alder, birch, hazel, especially within cities where systematic inventories are often missing or readily available. This research presents an approach produce high-resolution abundance maps tree us...
