How should spatial or phylogenetic eigenvectors be selected? A ten-year review and computer simulation study

By David Bauman

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....

Plant-bird interactions respond stronger to fragmentation at high than at low elevations

It's a fact. Biodiversity is not uniformly distributed over the Earth's surface. Some regions are lush with a rich...

Dispersal and alternative breeding site fidelity strategies in in the great crested newt

By: Mathieu Denoel

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...

Effects of grain size and niche breadth on species distribution modeling

 

By Thomas Connor

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...

Seasonal climate conditions and land use associated with trends in summer Monarch abundance

By Sarah P. Saunders and Elise F. Zipkin

 

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...

One of the fundamental problems currently facing scientists and conservationists is determining...

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.

By Hannah Sheppard Brennand

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