The downsizing of insular frugivore communities

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...

Global patterns in the effects of predator declines on sea urchins

The venomous long-spined sea urchin, Diadema setosum, gathers together on a coral reef to spawn.

Biologists have long been fascinated by the differences between tropical and temperate regions on...

Importance of migratory habitats

Northern pintail males and females.

By Ruscena Wiederholt and Brady Mattsson

Conserving or managing migratory species is notoriously challenging since their seasonal movements can cross international borders and continents – even...

If the apple doesn't fall far from the tree: Dispersal limitation and climatic niche conservatism shape dragonfly assemblages across Europe

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...

Structure in your data can undermine your model validations: the problem and some solutions

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...

No longer a black box: how did Maxent go open-source?

By Mary E. Blair and Robert P. Anderson

 

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...

Spatial variation in Allee effects influences patterns of range expansion

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.
