The biogeographic history of the African rain forests has been contentious. Phylogeography,
the study of the geographic distribution of genetic lineages within species, can highlight the …

The fossil record in tropical Africa suggests that dry conditions during the Ice Ages caused
expansion of savannahs and contraction of the rainforest. Forest refugia have been proposed …

Aim Arctic plant phylogeography has largely focused on seed plants, and studies on other
plant groups are necessary for comparison. Bryophytes have a unique life cycle and can be …

Although today the forest cover is continuous in Central Africa, this may have not always been
the case, as the scarce fossil record in this region suggests that arid conditions might have …

Inferring the evolutionary history of Mediterranean plant lineages from current genetic,
distributional and taxonomic patterns is complex because of a number of palaeoclimatic and …

Aim The aim of this study was to understand the origin of the forest flora currently found in the
Dahomey Gap ( DG ), a 200‐km‐wide forest‐savanna mosaic separating the West African …

Aim Palaeoecological records indicate that Pleistocene glaciations affected the African rain
forest, probably causing its fragmentation, which could explain phylogeographical breaks …

Polyploidy has rarely been documented in rain forest trees but it has recently been found in
African species of the genus Afzelia (Leguminosae), which is composed of four tetraploid …

Marine ecosystems occupy 71% of the surface of our planet, yet we know little about their
diversity. Although the inventory of species is continually increasing, as registered by the …

Combining genetic and morphological markers is a powerful approach for species delimitation,
much needed in tropical species complexes. Greenwayodendron (Annonaceae) is a …
