Selecting the best subset of covariates out a panel many candidates is key and highly influential stage species distribution modelling process. Yet, there currently no commonly accepted widely adopted standard approach by which to perform this selection. We introduce two-step "embedded" covariate selection procedure aimed at optimizing predictive ability parsimony models fitted in context high-dimensional candidate space. The combines collinearity-filtering algorithm (Step A) with three...
Predicting contemporary and future species distributions is relevant for science decision making, yet the development of high‐resolution spatial predictions numerous taxonomic groups regions limited by scalability available modelling tools. Uniting distribution (SDM) techniques into one high‐performance computing (HPC) pipeline, we developed N‐SDM , an SDM platform aimed at delivering reproducible outputs standard biodiversity assessments. was built around a spatially‐nested framework,...
Abstract Standard and easily accessible cross-thematic spatial databases are key resources in ecological research. In Switzerland, as many other countries, available data scattered across computer servers of research institutions rarely provided standard formats (e.g., different extents or projections systems, inconsistent naming conventions). Consequently, their joint use can require heavy management geomatic operations. Here, we introduce SWECO25 , a Swiss-wide raster database at 25-meter...
Background Dengue fever epidemic dynamics are driven by complex interactions between hosts, vectors and viruses. Associations climate dengue have been studied around the world, but results shown that impact of can vary widely from one study site to another. In French Guiana, climate-based models not available assist in developing an early warning system. This aims evaluate potential using oceanic atmospheric conditions help predict outbreaks Guiana.

Abstract We present forecasts of land-use/land-cover (LULC) change for Switzerland three time-steps in the 21 st century under representative concentration pathways 4.5 and 8.5, at 100-m spatial 14-class thematic resolution. modelled suitability each LULC class with a neural network (NN) using > 200 predictors accounting climate policy changes. improved model performance by data augmentation algorithm that synthetically increased number cells underrepresented classes, resulting an overall...
Spatial truncation in species distribution models (SDMs) might cause niche and model transferability issues, particularly when extrapolating to non‐analog environmental conditions. While broad calibration extents reduce they usually overlook local ecological factors driving distributions at finer resolution. Spatially‐nested hierarchical SDMs (HSDMs) address by merging (a) a global calibrated with broadly extended, yet typically low‐resolution, basic, imprecise data; (b) regional spatially...
The rapid loss of biodiversity in freshwater systems asks for a robust and spatially explicit understanding species' occurrences. As two complementing approaches, habitat suitability models provide information about potential occurrence, while environmental DNA (eDNA) based assessments indication actual occurrence. Individually, both approaches are used ecological studies to characterize biodiversity, yet they rarely combined. Here, we integrated high‐resolution with eDNA‐based aquatic...

Abstract Since the late 1990s, Nature’s Contributions to People (NCPs; i.e. ecosystem services) were used as a putative leverage for fostering nature preservation. NCPs have largely been defined and mapped at landscape level using land use cover classifications. However, NCP mapping attempts based directly on individual species are still uncommon. Given that shape ecosystems ultimately deliver NCPs, distribution data should highly meaningful results. This requires first establishing census...
Changes in climate and land use represent significant risks of biodiversity loss globally, affect ecological stability, impact nature's contributions to people (NCP, i.e. ecosystem services) compromise human livelihood. As framings conservation evolve consider the interdependence between species needs, there is a growing recognition importance NCP actions. However, knowledge on interactions spatial repartition remains limited. Here we show comprehensive assessment for 15 one – distribution...
