A new species of Trachylepis is described from Tinhosa Grande islet, São Tomé e Príncipe, Gulf of Guinea. Tinhosa Grande islet is a small (20.5 ha), isolated desert islet used by several bird communities as a nesting place. The new species is distinguished from its congeners by its color pattern, size and lepidosis. Due to its limited geographical distribution the new species appears to be one ...

A new genus and species of sea pen or virgulariid pennatulacean from the Gulf of Guinea in the tropical eastern Atlantic is described, and a key to the genera of the Virgulariidae is included. The new genus and species described here adds to the previously described five other genera of the family. It is distinguished by unique sclerite and polyp leaf characters from the superficially-similar g...

Reef ecosystems built during successive periods of Pleistocene sea level rise have shown remarkable persistence in coral community structure, but little is known of the ecological characteristics of reef communities during periods of low sea stands or sea level falls. We sampled the relative species abundance of coral, benthic foraminifera, and calcareous red algae communities from eight submer...

On New Guinea and its surrounding islands, an assortment of Carlia with weakly tricarinate to smooth dorsal scales has been variously recognized as C. fusca or members of ûic fusca group. The C. fusca group has never been defined or characterized explicitly, nor has any other group of Carlia. A preliminary cladistic analysis of the Australian, New Guiñean, and Sundan Carlia failed to identify s...

Benthic macroinvertebrates are helpful bio-indicators providing better understanding of modified and perturbed aquatic ecosystems. This study seeks to determine the ecological status diversity macroinvertebrate community in relation environmental variables western Nigerian offshore waters within Gulf Guinea. Macroinvertebrate samples were collected from five (5) sampling stations using a Van-ve...

African dust is transported to South America (SA) every winter and spring. Hypotheses suggest that either Western or Central North Africa (e.g., Bodélé Depression) the main source of dust, yet these notions remain largely untested with geochemical data. Using 2 years isotopic measurements (strontium neodymium) collected in SA integrated into a statistical model, we identified strong interannual...
