Aim In the Indo-Pacific, the mass of islands of the Indonesian archipelago constitute a major biogeographical barrier (the Indo-Pacific Barrier, IPB) separating the Pacific and Indian oceans. Evidence for other, more localized barriers include high rates of endemism at the Marquesas and other isolated peripheral islands in the Pacific. Here we use mitochondrial-sequence comparisons to evaluate ...

Nematodes represent the most abundant benthic metazoan of all seas and oceans, their relative importance increases with increasing water depth. Understanding biodiversity patterns this dominant phylum could be a critical step towards our comprehension evolutionary across largest biome biosphere. For instance, it has been assumed for long time that nematodes are ubiquitous depths, latitudes biog...

Batrachochytrium dendrobatidis, the causative agent of chytridiomycosis, was found in 24 of 109 (22%) frogs from Kibale National Park, western Uganda, in January and June 2006, representing the first account of the fungus in six species and in Uganda. The presence of B. dendrobatidis in an equatorial African montane forest raises conservation concerns, considering the high amphibian diversity a...

Pentaceratops sternbergii is an index fossil of the Kirtlandian LVA, and is known from the Fruitland and Kirtland formations, San Juan Basin, New Mexico and from the Williams Fork Formation of Colorado. We remove Chasmosaurus mariscalensis (Aguja Formation, Big Bend National Park, Texas) from Chasmosaurus and make it the type species of a new genus, Agujaceratops. Supposed chasmosaurine endemis...
