The flora of southern Africa has exceptional species richness and endemism, making it an
ideal system for studying the patterns and processes of evolutionary diversification. Using a …

Many of the diverse animals that consume floral rewards act as efficient pollinators;
however, others 'steal'rewards without 'paying'for them by pollinating. In contrast to the …

Mimicry is a classic example of adaptation through natural selection. The traditional focus of
mimicry research has been on defence in animals, but there is now also a highly-developed …

Aim Reproductive traits are important mediators of establishment and spread of introduced
species, both directly and through interactions with other life‐history traits and extrinsic …

Mating success of flowering plants depends strongly on the efficiencies of pollen removal
from flowers and its subsequent dispersal to conspecific stigmas. We characterized the …

Background The male fitness pathway, from pollen production to ovule fertilization, is
thought to strongly influence reproductive trait evolution in animal-pollinated plants. This …

Pollen limitation (PL) of seed production creates unique conditions for reproductive
adaptation by angiosperms, in part because, unlike under ovule or resource limitation, floral …

Premise of the Study We provide the largest phylogenetic analyses to date of Apocynaceae
in terms of taxa and molecular data as a framework for analyzing the evolution of vegetative …

Background Most angiosperms present flowers in inflorescences, which play roles in
reproduction, primarily related to pollination, beyond those served by individual flowers …

In this year celebrating the bicentenary of the birth of Darwin and the sesquicentennial of the
publication of Darwin's On the Origin of Species, the present paper aims to assess the …
