While the theory of micro-evolution by natural selection assigns a crucial role to competition,
its role in macroevolution is less clear. Phylogenetic evidence for a decelerating …

The importance of deterministic and stochastic processes in structuring ecological
communities is an enduring debate. Although this debate is nearly a century old, the extent …

Still food security has not been attained fully in many tropical African countries including
Ethiopia. However, the issue of food security achievement has been able to realize due to …

State of the art: Theory predicts that herbivore pressure should be weaker on islands than on
the mainland, owing to lower herbivore abundance and diversity because of dispersal …

Vascular epiphytes, which are specialised to spend their entire life cycle within trees, are
significant contributors to local ecosystem services. However, our current understanding of …

Abstract Two species of Bush Vipers, genus Atheris Cope, 1862, have been reported for the
continental island of Bioko, Gulf of Guinea–Atheris squamigera and a putatively undescribed …

Mantle-plume hotspot islands are a common focus of biogeographical studies, and models
for the growth of their biodiversity often incorporate aspects of their physical evolution. The …

abstract Aims The General Dynamic Model of oceanic island biogeography (GDM) predicts
how biogeographical rates, species richness, and endemism vary depending on island age …

Oceanic islands are recognized for their unique biota, which include remarkable examples
of trait evolution. This makes them excellent model systems for testing biogeographical and …
