Background Ocbil theory aims to develop hypotheses explaining the evolution and ecology
of, and best conservation practices for, biota on very old, climatically buffered, infertile …

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 …

Colour signals are the main floral trait for plant–pollinator communication. Owing to visual
specificities, flower visitors exert different selective pressures on flower colour signals of …

Urbanization is a widespread and rapidly growing threat to biodiversity, therefore we need a
predictive understanding of its effects on species and ecosystem processes. In this paper we …

Background and Aims According to the Grant–Stebbins model of pollinator-driven
divergence, plants that disperse beyond the range of their specialized pollinator may adapt …

Nectar robbers use a hole made in the perianth to extract nectar. Since robbers may modify
plant fitness, they play an important role by driving evolution on floral traits, sha** …

In plant–pollinator networks, the floral morphology of food plants is an important determinant
of the interaction niche of pollinators. Studies on foraging preferences of pollinators …

Many vertebrate species act as both plant pollinators and seed-dispersers, thus
interconnecting these processes, particularly on islands. Ecological multilayer networks are …

Aim We aimed to produce the first complete pollination network for Africa to test (1) whether
South African plants are unusually specialized in their interactions with pollinators, and (2) …

Pollinators are among the first to be lost when natural habitat is reduced to small patches
and this can have cascading effects on multiple plant species. Simultaneously, the loss of …
