The aim of the ecospat package is to make available novel tools and methods support spatial analyses modeling species niches distributions in a coherent workflow. written R language (R Development Core Team) contains several features, unique their implementation, that are complementary other existing packages. Pre‐modeling include niche quantifications comparisons between distinct ranges or time periods, measures phylogenetic diversity, data exploration functionalities (e.g. extrapolation...
Summary Species distribution models ( SDM s) have become a standard tool in ecology and applied conservation biology. Modelling rare threatened species is particularly important for purposes. However, modelling difficult because the combination of few occurrences many predictor variables easily leads to model overfitting. A new strategy using ensembles small was recently developed an attempt overcome this limitation has been tested successfully only single so far. Here, we aim test approach...
Abstract Ensembles of Small Models ( ESM ) represent a novel strategy for species distribution modelling with few observations. s are built by calibrating many small models and then averaging them into an ensemble model where the weighted their cross‐validated scores predictive performance. In previous paper (Breiner, Guisan, Bergamini, & Nobis, Methods in Ecology Evolution , 6 1210–1218, 2015), we reported two major findings. First, proved largely superior to standard terms performance...
Abstract Aim In the alpine life zone, plant diversity is strongly determined by local topography and microclimate. We assessed extent to which aspect its relatedness temperature affect species diversity, colonization disappearance of on summits a pan‐European scale. Location Mountain in Europe's zone. Methods Vascular their percentage cover were recorded permanent plots each cardinal direction 123 32 regions across Europe. For subset from 17 regions, resurvey data 6‐year soil series...
Abstract Aim Information on change in species’ environmental preferences (i.e., niche) is currently not included IUCN Red List criteria, although such information key for assessing whether species only lose geographic range but also part of their realized niche. Here, using niche size quantification and niche‐based distribution models (SDMs), we test predicted potential provide additional compared with the standard scores. Location Switzerland, national scale. Methods We simulated randomly,...
Europe is currently being re‐colonized by large carnivore species such as brown bear Ursus arctos , Eurasian lynx Lynx and grey wolf Canis lupus . Approximately one‐third of hosts at least one these species: they show permanent occurrence in some regions sporadic without reproduction others. We investigated potential future range expansions three carnivores using different analyses. First, we compared niche overlap between the historical, current occurrences n‐dimensional hypervolumes....
Abstract Ecosystems that provide environmental opportunities but are poor in species and functional richness generally support speciation as well invasion processes. These processes expected not to be equally effective along elevational gradients due specific ecological, spatial, anthropogenic filters, thus controlling the dispersal establishment of species. Here, we investigate gradients. We assess vascular plant number percentage endemic non‐native systematically three covering large parts...
Summary Climate change presents a particularly complex challenge in the context of flyway scale conservation migratory bird species as it requires coordinated action by multiple countries along these species’ routes. Coordinating responses understanding vulnerability and their habitats to climate at throughout each annual cycle. To contribute such understanding, we used distribution models assess exposure waterbird that are focus Agreement on Conservation African-Eurasian Migratory...
Abstract Recent studies show that light detection and ranging (Li DAR ) derived habitat variables significantly increase the performance accuracy of species distribution models ( SDM s). In particular, structure complex habitats such as forest can be accurately parametrized by an area‐wide, Li ‐based vegetation profile. However, evidence specific applications in real‐world conservation management still remains sparse. Here, we developed a resource selection for hazel grouse Bonasa bonasia...
Abstract Assessing the degree to which climate explains spatial distributions of different taxonomic and functional groups is essential for anticipating effects change on ecosystems. Most effort so far has focused above‐ground organisms, offer only a partial view response biodiversity environmental gradients. Here including both above‐ below‐ground we quantified topoclimatic control occurrence patterns >1,500 taxa phylotypes along c. 3,000 m elevation gradient, by fitting species...
Despite their importance for biodiversity and ecosystem services, wetlands are among the most threatened ecosystems globally. The conservation of many migratory waterbirds depends on a network key sites along flyways. However, suitability these is changing under climate change, it important that management individual in adapts to changes. Using bioclimatic models also account changes inundation, we found projected change will reduce habitat at 57.5% existing Critical Sites within...
