Ecological processes are central to the formation of new species when barriers to gene flow
(reproductive isolation) evolve between populations as a result of ecologically‐based …

Hybridization between naturally co-occurring species that normally do not interbreed is
being documented following anthropogenic habitat modifications for an increasing number …

The origin of biological diversity, via the formation of new species, can be inextricably linked
to adaptation to the ecological environment. Specifically, ecological processes are central to …

Abstract Since Darwin published the “Origin,” great progress has been made in our
understanding of speciation mechanisms. The early investigations by Mayr and Dobzhansky …

▪ Abstract Like South Africa's Greater Cape Floristic Region, the Southwest Australian
Floristic Region (SWAFR) is species rich, with a Mediterranean climate and old, weathered …

Phylogeography, born to bridge population genetics and phylogenetics in an explicit
geographic context, has provided a successful platform for unveiling species evolutionary …

Environmental gradients are very common and many plant species respond to them through
adaptive genetic change. This can be a first step along a continuum of change that leads …

This research level text documents the latest advances in odonate biology and relates these
to a broader ecological and evolutionary research agenda. Despite being one of the …

Speciation often involves the evolution of numerous prezygotic and postzygotic isolating
barriers between divergent populations. Detailed knowledge of the strength and nature of …

While homoploid hybridization was viewed as maladaptive by zoologists, the possibility that
it might play a creative role in evolution was explored and debated by botanists during the …
