The accumulation of biodiversity in tropical forests can occur through multiple allopatric and
parapatric models of diversification, including forest refugia, riverine barriers and ecological …

The tropical vegetation of Africa is characterized by high levels of species diversity but is
undergoing important shifts in response to ongoing climate change and increasing …

Organismal traits interact with environmental variation to mediate how species respond to
shared landscapes. Thus, differences in traits related to dispersal ability or physiological …

Cycles of Quaternary climatic change are assumed to be major drivers of African rainforest
dynamics and evolution. However, most hypotheses on past vegetation dynamics relied on …

Phylogeographic studies on widespread rainforest species from West and Central Africa
often reveal genetic discontinuities. These discontinuities can originate from past barriers to …

The genus Sericanthe was established and its species were revised 30 years ago by one of
