The range of resources that a species uses (ie its niche breadth) might determine the
geographical area it can occupy, but consensus on whether a niche breadth–range size …

Terrestrial ectotherms are likely to face increased periods of heat stress as mean
temperatures and temperature variability increase over the next few decades. Here, we …

The prevalence of autopolyploids in angiosperms has long been a subject of debate.
Müntzing (1936) and Darlington (1937) concluded that autopolyploids were common and …

Microbes form fundamental bases of every Earth ecosystem. As their key survival strategies,
some microbes adapt to broad ranges of environments, while others specialize to certain …

Understanding the mechanisms of rapid adaptive radiation has been a central problem of
evolutionary ecology. Recently, there is a growing recognition that hybridization between …

Species hybridization can lead to fitness costs, species collapse, and novel evolutionary
trajectories in changing environments. Hybridization is predicted to be more common when …

The importance of dispersal rates and distances has long been appreciated by ecologists
and evolutionary biologists. An emerging field of research is revealing how temporal …

Aim The geographical distribution of bacteria is an important, but poorly understood, topic in
microbial ecology. A major question is how broadly distributed generalist taxa, and limitedly …

Theory building is an integral part of biological research, in general, and of speciation
research, in particular. Here, I review the modeling work on speciation done in the last 10 …

Studies of speciation typically investigate the evolution of reproductive isolation between
populations, but several other processes can serve as key steps limiting the formation of …
