Aim: The persistence and stability of habitats through time are considered predictors of high levels of biodiversity in some environments. Long-term habitat persistence and stability may explain the species-rich, endemic forest fauna and flora of the Eastern Afromontane Biodiversity Region (EABR). Using comple- mentary phylogenetic and biogeographical approaches, we examine evolution- ary patterns in EAR brevicipitid frogs. Using these data, we test whether brevicipitid history reflects patterns of long-term forest persistence and/or sta bility across the EABR.

Location: East Africa.

Methods: A dated phylogeny for brevicipitids was constructed using two nuclear and three mitochondrial markers. Alternative diversification modes were used …

A Samoan Hebeloma With Phylogenetic Ties To The Western Pacific, Bradley R. Kropp

Biology Faculty Publications

Hebeloma ifeleletorum is described as a new species from American Samoa. Based on analyses of ITS and combined nLSU-ITS datasets H. ifeleletorum clusters with but is distinct from described species that have been placed in the genus Anamika by some. The phylogenetic relationship of H. ifeleletorum to the genus Anamika from Asia and to other species from Australia and New Caledonia suggests that H. ifeleletorum has origins in the western Pacific.
