	abstract = {We surveyed three National Forests in north-western and south-eastern Liberia for amphibians. Forty species were found including five first national records: Afrixalus nigeriensis, Astylosternus occidentalis, Bufo superciliaris, Chiromantis rufescens and Phrynobatrachus villiersi. Following the 1UCN Red List categories and criteria, eleven species are Near Threatened, two are Vulnerable and two Endangered. Bufo superciliaris is listed under CITES. All three forests under investigation harbour an amphibian community mainly consisting of forest specialists that are endemic to the Upper Guinea Forest zone. All investigated sites showed a high potential for conservation, although the presence of some invasive species is a hint that alteration of natural forests has already occurred. We also provide a list of all reptiles encountered to account for the deficiency of data for these vertebrates in Liberia.},

	abstract = {<p>Our recent surveys of the herpetological diversity of the West African Togo Hills documented a total of 65 reptile and amphibian species, making Kyabobo National Park one of the most diverse sites surveyed in Ghana. We provide accounts for all species recorded along with photographs to aid in identification. We recorded 26 amphibians, including six new records for Kyabobo N. P., one of which is a record for the Togo Hills. Our collection of reptile species (22 lizards, 16 snakes, and one crocodile) also provides new records and range extensions for Kyabobo N. P., such as the first observation of the dwarf crocodile, Osteolaemus tetraspis. Amphibian species still lacking from our surveys in the Togo Hills include several species that are adapted to fast running water or large closed forests, like the Togo toad, Bufo togoensis and the slippery frog, Conraua derooi. Appropriate habitat for such species still remains in Kyabobo, highlighting the need for additional survey work. We draw attention to the importance of conserving forest stream habitats, which will in turn help ensure the persistence of forest-restricted species. We also highlight those species that may prove most useful for evolutionary studies of West African rain forest biogeography.</p>

	abstract = {We describe a new frog species of the genus Cardioglosso from the Upper Guinean forests of West Africa. Cardioglosso occidentalis, new species, is found in primary rainforests in Ghana, Ivory Coast, Guinea, Liberia, and Sierra Leone. We demonstrate that this species is morphologically and genetically distinct from C. leucomystax, the species to which these populations were previously assigned. Cardioglossa occidentalis differs from similar congeners by the following combination of markings: fusion or near fusion of all three dorsal lobes (cephalic, scapular, and lumbar); prominent white line extending anteriorly from arm terminates ventral to eye; dark mask extending posteriorly from eye continues unbroken beyond posterior border of scapular lobe; lateral body covered in very few, large dark spots rimmed with thin white. Cordioglosso occidentalis appears related to C. leucomystax, C. melanoguster, and C. schioetzi. This description brings the number of Cardioglossa species to 16.},

	abstract = {We report oil the amphibians of three sites in the Fouta Djallon highlands in central-northern Guinea. During Our Survey we recorded at least 25 frog species, including two first country records (Kassina fusca and Leptopelis bufonides) and one species new to science (Conraua sp.). Most of the recorded frogs were typical savanna or farmbush species with a distribution range that exceeds West Africa. Only a few species were more closely connected to forest habitats. For several species our records in the Fouta Djallon represent large range extensions. Despite the generally high degradation level of forests in the Fouta Djallon, the investigated sites all still harboured typical forest frogs and thus may represent last islands of forest in a nowadays savanna dominated landscape. All sites therefore have a high potential for conservation, especially the forest surrounding the Saala Waterfalls.},

	abstract = {Habitat degradation alters the dynamics and composition of anuran assemblages in tropical forests. The effects of forest fragmentation on the composition of anuran assemblages are so far poorly known. We studied the joint influence of forest fragmentation and degradation on leaf-litter frogs. We specifically asked whether the processes structuring leaf-litter anuran assemblages in fragmented forests are the same as those in continuous forests. We analyzed anuran assemblages with respect to habitat characteristics, including fragmentation and degradation parameters. In comparison with continuous forests, species richness and diversity were lower and assemblage composition was altered in forest fragments. These changes seemed to be mainly caused by habitat degradation rather than forest fragmentation. Availability of aquatic sites for breeding, vegetation structure (including those variables indicating degradation), and leaf-litter cover bad the most influence on the presence of single species. The comparatively small impact of fragmentation on anurans might be due to the location of the study area; it still possessed large tracts of continuous forest. These forest blocks may stabilize the regional rainforest climate and thus weaken the effects of fragmentation.},
