Figure 1. Illustration - Exploring the past of a food web.

By Pierre Olivier

Since the very first representation of an ecological network (Camerano 1880), food webs have become an important tool to explore and summarize the...

Finding the ‘best’ habitat suitability model

By Edward Gregr and Kai Chan

How is a habitat model’s complexity related to its forecasting skill? Our recent Ecography paper addressed this question using multiple data...

Defaunation and fragmentation erode small mammal diversity dimensions in tropical forests

Figure 1: Best-fitting structural equation model (full direct + indirect model). Positive and negative pathways are indicated by black and gray lines, respectively. Arrow thickness is scaled to illustrate the relative strength of effects and significant coefficients are...

A parsimonious view of the parsimony principle in ecology and evolution

The curve-fitting problem. The choice of the most plausible hypothesis is based on an arbitrary balance between goodness-of-fit and simplicity criteria. The red curve is the simplest, indicating a linear relationship between the two variables, but also the worst-fit. The...

recurse: an R package to analyze spatiotemporal patterns in revisitations from animal movement data

by Chloe Bracis

Animal movements are linked to both quotidian activities as well as larger questions of survival and reproduction. For example, one might think of an animal moving to locate food, or, on the other side of the coin, moving to avoid...

Tropical moths in the mountains are larger

By Gunnar Brehm

New study in biodiversity hotspot studied correlation between size of tropical moths and their elevational distribution

Researchers from three universities have measured more than 19 000 tropical moths from 1100 species...

Using simplified settings to advance ecological theory: a lesson from the subterranean world
