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...

Latitudinal variation in resistance and tolerance to herbivory of a salt marsh shrub

By Steve Pennings and Kazimierz Więski.

A new study by Kazimierz Więski and Steven Pennings contributes to the biogeography of plant antiherbivore strategies. Plants can resist herbivore's...

One of the most common notions in ecology is that species richness has a positive relationship with habitat...

Seasonal cycles of diversity and similarity in a Central American rainforest butterfly community

V. Grøtan, R. Lande, I. A. Chacon and P. J. DeVries

Lowland tropical rainforests harbor the greatest insect diversity on earth, and ecologists have repeatedly shown that wet and dry seasons are correlated with insect abundances. Despite its importance for understanding...

Koalas need to balance their requirements for food and shade

You would think that once a koala found a good tree for feeding, they would stay put. This is not the case according to...

Energetic costs as potential drivers of cetacean habitats in the southwest Indian Ocean

Cetaceans are large vertebrates which occupy the highest trophic levels of pelagic food webs. At the individual scale, it has been shown that cetaceans select their food on the basis of their energetic costs. Cetaceans with the highest energetic costs select the highest...
