Acute and chronic effects of acidic pH on four subtropical frog species
(Water Research Commission, 2016)Acidic precipitation is implicated as a possible cause of global amphibian decline. Even protected areas such as Kruger National Park receive acid rain which may lead to possible negative effects on the park’s natural ... -
Amphibian diversity and breeding behaviour in the Okavango Delta
(North-West University, 2010)Amphibians are of great ecological importance and a loss of species will have widespread and dire consequences. Recent population declines and extinctions have resulted in amphibians being labelled the most threatened ... -
Cosmocercidae (Nematoda) of selected species of amphibians of South Africa
(North-West University (South Africa), 2021)Recent studies revealed that parasites outweigh their host species in terms of species richness. This suggests parasitism as the most common lifestyle. In present times, parasites have an even higher species richness and ... -
Diversity and distribution of anuran blood parasites within the Vhembe Biosphere
(North-West University (South Africa), 2023)The Soutpansberg mountain range, the most northern mountain range in South Africa, forms part of the Vhembe Biosphere Reserve, a highly diverse region comprising at least three biomes and 23 different vegetation types. ... -
Estimating herd immunity to amphibian Chytridiomycosis in Madagascar based on the defensive function of amphibian skin bacteria
(Frontiers Media, 2017)For decades, Amphibians have been globally threatened by the still expanding infectious disease, chytridiomycosis. Madagascar is an amphibian biodiversity hotspot where Batrachochytrium dendrobatidis (Bd) has only recently ... -

Herpetofaunal survey of the Khaudum–Ngamiland dispersal area in Namibia
(North-West University (South Africa), 2023)An extensive Herpetofaunal survey of three under researched areas in North–eastern Namibia (all forming part of the Khaudum Ngamiland dispersal area) was conducted. The areas in question were the Nyae Nyae conservancy, ... -
Hotspots of stream tadpole diversity in forest and agricultural landscapes in Ranomafana, Madagascar
(Springer, 2020)Logging and human-induced conversion of natural forests into agricultural areas are major drivers of biodiversity loss in the tropics. Anuran larvae can be highly diverse, can reach high biomass and can play important roles ... -
Linking organochlorine exposure to biomarker response patterns in Anurans: a case study of Müller’s clawed frog (Xenopus muelleri) from a tropical malaria vector control region
(Springer, 2018)Organochlorine pesticides are highly persistent in aquatic ecosystems. Amphibians, specifically anurans, play an intricate part in the aquatic food web, and have very permeable skin which makes them prone to bioaccumulation ... -
Novel information on the morphology, phylogeny and distribution of camallanid nematodes from marine and freshwater hosts in South Africa, including the description of Camallanus sodwanaensis n. sp.
(Elsevier, 2019)Four species of previously known nematodes from the family Camallanidae were found from different hosts in South Africa: Batrachocamallanus xenopodis from the frog Xenopus muelleri, Paracamallanus cyathopharynx and ...
