Abstract:

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.

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

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

Out of the 86 screened Malagasy frog species, we recovered polystomes from 25 in the families Ptychadenidae and Mantellidae. Molecular phylogenetic analysis uncovered an unexpected diversity of polystome species belonging to two separate clades: one forming a lineage within the genus Metapolystoma , with one species in Ptychadena and several species i

Abstract:

(Uploaded by Plazi for the Bat Literature Project) This study describes the foraging strategies, foraging areas, and roosts used by four female radio‐tagged Nycteris grandis along the Zambezi River in Mana Pools National Park in Zimbabwe. The bats exhibited two foraging strategies, sometimes hunting from perches, other times flying continuously close to the ground. Some individuals used one strategy more than the other. During the study, the bats fed mainly on frogs, selecting only Ptychadena anchietae ; they also took crickets, moths and cicadas. Each bat usually consumed two frogs each night

The dietary constituents of 72 specimens of Ptychadena spp. (P. mascareniensis, P. longirostris, P. bibroni, P. pumilio and P. oxyrhynchus), collected from a monoculture plantation (Oil Palm) and a natural rainforest environment were investigated. A total of 87 prey items comprising of 12 taxa were recorded from the stomachs of the frogs examined. More prey item taxa were recorded in the forest frogs than from the altered environment of the monoculture plantation. Lepidoptera (10.34%), Mollusca (5.75%), Diptera (2.30%), Isopoda (3.45%), Blatteria (2.30%), Annelida (1.15%), Myriapoda (2.30%) an

AbstractAnurans from locations in the rainforest, derived savannah and a monoculture plantation in Nigeria were examined for infection with strigeoid trematode larvae. Two types of metacercarial cysts were recovered. The cyst type I (rounded with fringe projections) occurred in tree frogs from the Okomu National Park, at Usen (derived savannah) and the Okomu Oil Palm Plantation (OOPP). The cyst type II was recovered from A. dorsalis and Ptychadena bibroni collected at OOPP. The cysts were ovoid in shape, devoid of projections at the fringes and were not subject to trypsin action.

Summary The parasitic infections of 125 anurans belonging to 13 taxa from Ase community in Delta State in the Niger Delta of Nigeria was investigated. An overall prevalence of 77.6% was recorded and the 32 parasites recovered included one pentastomid, four cestode, four monogenean, ten digenean and thirteen nematode taxa. Among the anurans examined, Ptychadena bibroni harboured the highest number of parasites. Most of the parasites encountered were adults but some occurred as larvae, which either used the amphibians as intermediate or transport hosts. Hylarana galamensis is considered an accid

Abstract:

AbstractInvestigations undertaken on the monogeneans of amphibians in Nigeria have shown that host ecology has an influence on the distribution of these monogeneans. Amphibians from humid environments of the rainforest, a freshwater swamp and mangrove harboured no monogeneans, whereas those occurring in drier conditions in the savannah-mosaic and guinea savannah yielded five species of polystomatid parasites: Polystoma prudhoei from Bufo regularis, Polystoma galamensis from Rana galamensis, Eupolystoma alluaudi from Bufo regularis and Bufo maculatus, and two unidentified Polystoma species from

AbstractExperiments with Pelomedusa subrufa, a widespread African freshwater turtle, showed that this species consumed large quantities of tadpoles. Tadpoles preyed upon, comprised between 0.05 and 21.55% of the turtle's biomass. This demonstrated that Pelomedusa subrufa was neither gape limited nor did it ignore very small prey. Tadpoles with an ovoid body shape (Hemisus marmoratus, Hyperolius nitidulus, Ptychadena maccarthyensis), which shared, under natural conditions, the pond bottom microhabitat with the turtles, were more threatened than the robust tall-finned Kassina tadpoles that lived

Abstract:

Biological invasions are on the rise, with each invader carrying a plethora of associated microbes. These microbes play important, yet poorly understood, ecological roles that can include assisting the hosts in colonization and adaptation processes or as possible pathogens. Understanding how these communities differ in an invasion scenario may help to understand the host’s resilience and adaptability. The Asian common toad, Duttaphrynus melanostictus is an invasive amphibian, which has recently established in Madagascar and is expected to pose numerous threats to the native ecosystems. We char

This article provides the first data on amphibian diversity in the Yoko Forest Reserve, located in the Democratic Republic of the Congo. During twenty-four field sampling campaigns organized over a period of twelve months, amphibians were collected from nocturnal surveys supported by three techniques: visual spotting using a headlamp, systematic searching of habitats and acoustic hearing of vocalizations. A total of 5707 amphibians in 10 families, 17 genera and 33 species were recorded throughout the study area. The Hyperoliidae and Arthroleptidae families were the most diverse, with Amnirana

A toxic activity was found in a leaf extract of Gambeya boiviniana (Chrysophyllum bovinianum), an endemic medicinal Sapotaceae of Madagascar. A purification process including a butanol fractionation and neutral lead acetate precipitation allowed to obtain a partially purified toxic extract (E2) from a clear, brick-red crude hydro-alcoholic extract (CE) with a bitter taste. The toxic principles were bitter, thermostable, soluble in water, in ethanol and in butanol. They were not precipitable by lead neutral acetate. They could be flavonons, unsaturated sterol, triterpenes or phenol compounds. B
