1. Once neglected, the role of facilitative interactions in plant communities has received
considerable attention in the last two decades, and is now widely recognized. It is timely to …

Trees do not form a natural group but share attributes such as great size, longevity, and high
reproductive output that affect their mode and tempo of evolution. In particular, trees are …

Species distribution modelling is central to both fundamental and applied research in
biogeography. Despite widespread use of models, there are still important conceptual …

Evolutionary dynamics shape the living world around us. At the centre of every evolutionary
process is a population of reproducing individuals. The structure of that population affects …

Bacterial feeding has evolved toward specific evolutionary niches and the sources of energy
differ between species and strains. Although bacteria fundamentally compete for nutrients …

The genetic evolution of altruism (ie, a behavior resulting in a net reduction of the survival
and/or reproduction of an actor to benefit a recipient) once perplexed biologists because it …

The first generation of research on animal social networks was primarily aimed at
introducing the concept of social networks to the fields of animal behaviour and behavioural …

This article is a brief introduction to the special issue 'Evolution of cooperation'published by
the Journal of Theoretical Biology to mark its 50th anniversary. Cooperation is a favorite …

The evolution of mutualisms presents a puzzle. Why does selection favour cooperation
among species rather than cheaters that accept benefits but provide nothing in return? Here …

Heterotypic cooperation—two populations exchanging distinct benefits that are costly to
produce—is widespread. Cheaters, exploiting benefits while evading contribution, can …
