This work is an inventory of the amphibians of Fouta-Djallon that has provided two lists of amphibians from this area of Guinea. The first is a list of amphibian species that have been reported in Fouta-Djallon. These are the twenty-seven (27) species that are : Arthroleptis formosus Rödel et al.

Abstract:
The study of specimens of the genus Ptychadena of the herpetological collection of the Museo Nacional de Ciencias Naturales de Madrid reveals the first record of Ptychadena schillukorum from Mauritania, extending the known distribution range of the species in West Africa more than 450 km northwards. A key is provided for the four Mauritanian species of Ptychadena to solve problems in identification encountered in previous studies.

Résume : Cette étude qui avait pour objectif principal de caractériser la structure des peuplements d’Anoures (amphibiens) dans le bassin versant de la rivière Bumbu à Kinshasa en RDC afin de comprendre le mode de distribution et d’expliquer les éléments qui sont à la base de sa structuration. Il a permis de capturer deux cent quinze (215) spécimens d’Anoures ont été capturés et réunis dans 5 familles et 15 espèces. La famille des Hyperoliidae est la plus représentée avec 5 espèces, suivie par les familles de Bufonidae et de Ptychadenidae avec 4 espèces chacune et par celles de Dicroglossidae

Abstract:
Ethiopia is a world biodiversity hotspot and harbours levels of biotic endemism unmatched in the Horn of Africa, largely due to topographic—and thus habitat—complexity, which results from a very active geological and climatic history. Among Ethiopian vertebrate fauna, amphibians harbour the highest levels of endemism, making amphibians a compelling system for the exploration of the impacts of Ethiopia's complex abiotic history on biotic diversification. Grass frogs of the genus Ptychadena are notably diverse in Ethiopia, where they have undergone an evolutionary radiation. We used molecular da

Specimens were collected using the Visual Encounter and Acoustic survey methods. A total of 232 individuals belonging to four families, eight genera and twelve species were recorded. Species encountered included Afrixalus dorsalis, Amnirana albolabris, Arthroleptis poecilonatus, Bufo maculatus, Hoplobatrachus occipitalis, Hyperolius concolor, Leptopelis hyloides, Ptychadena bibroni, P. longirostris, P. mascareniensis, P. oxyrhynchus and P. pumilio.

Abstract:
Polystoma africanum was originally described from a single specimen recovered from the common African toad, Amietophrynus regularis. The parasite has also been reported from the Angola river frog, Amietia angolensis, in Ethiopia; the Mascarene ridged frog, Ptychadena mascareniensis, in Uganda; and Ptychadena sp. in Zaire. One of the characters ascribed to this species was the lack of caecal anastomoses. Based on this and other characteristics, other polystomes from frog species like Pty. mascareniensis have been identified as P. africanum. A large collection of parasite specimens retrieved fro

Abstract:
Frogs of the genus Ptychadena that inhabit the Ethiopian highlands serve as a model system to understand biogeography, diversification, and adaptations to high elevations. Despite recent studies focusing on the systematics of this group, the taxonomy of the Ptychadena neumanni species complex remains only partially resolved, owing largely to the morphological resemblance of its members. Here, the taxonomy of this historically problematic group of frogs is revised by integrating morphological and molecular analyses on both century-old type specimens and more recently collected material.

Ces données n’étant malheureusement pas toujours accessibles, même à partir d’études poussées sur les espèces d’intérêt, les objectifs des gestionnaires des espaces naturels n’en sont que plus difficiles à atteindre.

AbstractThis chapter reviews the diversity, evolutionary relationships, ecology, and conservation of the Gulf of Guinea oceanic islands’ endemic caecilian and anuran fauna. A total of nine amphibian species (representing five families) are known from São Tomé and Príncipe islands, all of which are endemic. No amphibians have been reported from Annobón. Taxonomic research on this group of animals began in the second half of the nineteenth century with subsequent refinement following the advent of molecular techniques. The presence of several amphibians from distinct evolutionary lineages is une
