Abstract While there is a clear demand for scenarios that provide alternative states in biodiversity with respect to future emissions, thorough analysis and communication of the associated uncertainties still missing. Here, we modelled global distribution ~11,500 amphibian, bird mammal species project their climatic suitability into time horizon 2050 2070, while varying input data used. By this, explore originating from selecting models (SDMs), dispersal strategies, circulation (GCMs),...
Abstract Identifying species that are both geographically restricted and functionally distinct, i.e. supporting rare traits functions, is of prime importance given their risk extinction potential contribution to ecosystem functioning. We use global distributions functional for birds mammals identify the ecologically species, understand characteristics, hotspots. find disproportionately represented in IUCN threatened categories, insufficiently covered by protected areas, some them sensitive...
Abstract. To support the assessments of Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), IPBES Expert Group Scenarios Models is carrying out an intercomparison biodiversity ecosystem services models using harmonized scenarios (BES-SIM). The goals BES-SIM are (1) to project global impacts land-use climate change (i.e., nature's contributions people) over coming decades, compared 20th century, a set common metrics at multiple scales, (2) identify model...
Species distribution models (SDMs) are statistical tools that relate species observations to environmental conditions retrieve ecological niches and predict species' potential geographic distributions. The quality robustness of SDMs clearly depend on good modelling practices including ascertaining the relevance predictors for studied choosing an appropriate spatial resolution (or ‘grain size'). While past studies showed improved model performance with increasing sessile organisms, there is...
Abstract Across the globe, invasive alien species cause severe environmental changes, altering composition and ecosystem functions. So far, mountain areas have mostly been spared from large‐scale invasions. However, climate change, land‐use abandonment, development of tourism increasing ornamental trade will weaken barriers to invasions in these systems. Understanding how react native communities influence their success is thus prime importance a management perspective. Here, we used...
Abstract Aim Seasonal bird migration is one of the most fascinating global ecological phenomena. Yet, biogeographic scenarios and climatic drivers that led single species or entire lineages to evolve seasonal between disjunct breeding wintering ranges remain unclear. Based on distribution phylogenetic data for all birds worldwide, we explored context evolutionary emergence geographic in birds. Location Global. Taxon The Aves class (9,819 species). Methods We used worldwide phylogeny birds,...
Abstract Local adaptation patterns have been found in many plants and animals, highlighting the genetic heterogeneity of species along their range distribution. In next decades, global warming is predicted to induce a change selective pressures that drive this adaptive variation, forcing reshuffling underlying allele distributions. For with low dispersion capacity long generation time such as trees, rapidity could impede migration beneficial alleles lower track changing environment....
Climate and land cover changes are important drivers of the plant species distributions diversity patterns in mountainous regions. Although need for a multifaceted view based on taxonomic, functional phylogenetic dimensions is now commonly recognized, there no complete risk assessments concerning their expected changes. In this paper, we used range distribution models an ensemble‐forecasting framework together with regional climate projections by 2080 to analyze potential threat more than...
Modelling ecological niches of migratory animals requires incorporating a temporal dimension, in addition to space. Here, we introduce an approach model multigenerational insects using time-partitioned environmental variables (by months and years) time- behaviour-partitioned records (breeding reproductive habitat). We apply this methodology modelling the Palearctic-African cycle Painted Lady butterfly ( Vanessa cardui ), based on data encompassing 36 years (646 breeding sites from 30...
Summary Climate change and extreme events, such as drought, threaten ecosystems world‐wide in particular mountain ecosystems, where species often live at their environmental tolerance limits. In the European Alps, plant communities are also influenced by land‐use abandonment leading to woody encroachment of subalpine alpine grasslands. this study, we explored how forest–grassland ecotone Alpine tree lines will respond gradual climate warming, drought events terms forest expansion rates,...
Abstract Invasive species can encounter environments different from their source populations, which may trigger rapid adaptive changes after introduction (niche shift hypothesis). To test this hypothesis, we investigated whether postintroduction evolution is correlated with contrasting environmental conditions between the European invasive and ranges in Asian tiger mosquito Aedes albopictus . The comparison of niches occupied population revealed more than 96% overlap niches, supporting niche...
Abstract Environmental features impacting the spread of invasive species after introduction can be assessed using population genetic structure as a quantitative estimation effective dispersal at landscape scale. However, in case an ongoing biological invasion, deciphering whether represents connectivity or founder effects is particularly challenging. We examined modes (natural and human‐aided) factors (landscape founders history) shaping range edge populations Asian tiger mosquito, Aedes...
Abstract Aim When modelling the distribution of animals under current and future conditions, both their response to environmental constraints resources’ these need be taken into account. Here, we develop a framework predict large herbivores global change, while accounting for changes in main resources. We applied it Rupicapra rupicapra , chamois European Alps. Location The Bauges Regional Park (French Alps). Methods built sixteen plant functional groups ( PFG s) that account chamois’ diet...
Abstract The Western Paleartic species of Neocrepidodera Heikertinger (Coleoptera: Chrysomelidae: Galerucinae: Alticini) mostly occur in medium and high elevation ecosystems particularly sensitive to climate change. Here, using ensemble projections from state‐of‐the‐art habitat suitability modelling techniques, we investigated how change associated changes host availability may affect the persistence three pairs closely related taxa. Modelled niches patterns reflected current distributions...

Abstract Foundation plants shape the composition of local biotic communities and abiotic environments, but impact a plant's intraspecific variations on these processes is poorly understood. We examined links in alpine cushion moss campion ( Silene acaulis ) two neighboring mountain ranges French Alps. Genotyping revealed genetic clusters matching known subspecies. The exscapa subspecies was found both limestone granite, while longiscapa one only limestone. Even similar bedrock, soils from S....
The field of distributional ecology has seen considerable recent attention, particularly surrounding the theory, protocols, and tools for Ecological Niche Modeling (ENM) or Species Distribution (SDM). Such analyses have grown steadily over past two decades—including a maturation relevant theory key concepts—but methodological consensus yet to be reached. In response, following an online course taught in Spanish 2018, we designed comprehensive English-language covering much underlying methods...
Abstract Questions Shrub vegetation has been expanding across much of the rapidly changing Arctic. Yet, there is still uncertainty about underlying drivers shrub community composition. Here, we use extensive surveys and a trait‐based approach to answer following questions: which abiotic biotic factors explain abundance species functional groups in Arctic tundra, can interpret these relationships using plant traits related resource acquisition? Location Nuup Kangerlua (Godthåbsfjord), western...
