Optimal and default Maxent models for the Malagasy rodent Eliurus majori (logistic output). Results correspond to the unfiltered dataset (top) and filtered dataset (bottom), and three ways of determining model settings: AICc (left), sequential criteria based on...
Figure 1. Bird species assemblage were predicted using the spatially-explicit species assemblage modelling framework – SESAM – that applies successive filters to constrained predictions of richness and composition obtained by stacking species distribution models that...
Recent observation of decreases in the body size of endothermic animals lead to the proposal that body size decline is the third universal response to climate warming (after distribution range and phenological shifts). However, the mechanisms...
Ecologists have collected reams of field data, involving much sweat and toil, to explain how competing species — those with similar diets or habitat preferences —...
Figure 1. Example of co-occurrence network based on presence data. a) Co-occurrence network with locations (green filled circles) and taxa (blue filled circles) and b) Binary matrix of species co-occurrences.
Cold-adapted taxa are experiencing severe range shifts due to climate change and are expected to suffer a significant reduction of their climatically suitable habitats in the next few decades. However, it has been proposed...
In what context was our study undertaken? Eigenvector mapping techniques are widely used by ecologists and evolutionary biologists to describe and control for spatial and/or phylogenetic patterns in their data....
We aimed at examining whether distinct breeding site fidelity strategies may coexist at the intra-population level and how breeding resource characteristics and individual phenotype may affect these strategies in pond-breeding...

Despite the impact of global climate change being documented on a broad
range of biotas, the effects of altered temperatures on biological
communities...
A large body of work in ecology of conservation is devoted to figuring out where species truly are and what causes them to be in some places and not others. Termed species distribution modeling, or SDM for short, this...
Migration is a captivating phenomenon that continues to fascinate both biologists and the public. In many species—ranging from the smallest insects to the largest mammals—thousands or even...
This Aldabra giant tortoise Aldabrachelys gigantea is eating the fruit of an endemic Pandanus plant on Rodrigues. There were no frugivores left that were large enough to be able to swallow and disperse their seeds until these tortoises were introduced to...
