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...
Conserving or managing migratory species is notoriously challenging since their seasonal movements can cross international borders and continents – even...
Adaptations to habitats with low temporal and spatial stability (such as the depicted area in the Scottish Highlands, where air temperatures can drop below minus 10°C until Summer) allowed lentic dragonfly species to recolonize areas north of the 0°C isotherm at the Last...
Statistical models in ecology are used not just to describe the present state of natural systems, but also to predict their change or development over time. Such models are fairly simple to create and have thus become ubiquitous in all areas of ecological research. To...
Fifteen years ago, Steven Phillips, a computer science researcher at AT&T Labs from South Africa, walked a few blocks from his apartment in New York City to the American Museum of Natural...
In simulations comparing a population spread in a spatially homogenous (left) versus patchy (right) landscapes, variation in the Allee effect induces variation in spread patterns and increases the overall rate of spread.
The sigmodontine rodent genus Eligmodontia includes highly specialized desert-dwellers in the Southern Cone of South America. Species of gerbil mice have inflated auditory bullae, and are also capable of bipedal jumping and elevated urine concentration. Photo by...
