New studies on fairy circles need to account for new observations on their spatial patterns

The fairy circles of Namibia are currently subject to a lively debate on their origin, and they provide a textbook example of how progress is made in science. Hypotheses that were commonly accepted are challenged by a set of new observations that favor

Have behavioural ecologists given up on the search for the fundamental niche?

Have behavioural ecologists given up on the search for the fundamental niche?

by Manuela Panzacchi

No, not at all. Although, strictly speaking, fundamental niches are inestimable theoretical constructs, they are too important to be forgotten....

Amphibians closer to the pole respond stronger to global warming

By Tobias Uller

 

In a warmer world, spring will be earlier. The increase in temperature is not the same across the globe, however, and the highest rate of warming is found at high latitudes. It is therefore not very surprising that,...

Webinar on niche modeling and the use of MaxEnt

By Professor Rob Anderson

In this seminar, I will first provide an overview of my perception of the field of ecological niche modeling, within the larger arena of biodiversity informatics, and then provide worked examples with tropical mammals.  In framing the field, I...
