Overland movement in African clawed frogs (Xenopus laevis): a systematic review
African clawed frogs (Xenopus laevis) are often referred to as `purely aquatic' but there are many publications which suggest extensive overland movements. Previous reviews which considered the topic have not answered the ...
Science and education at the Centre for Invasion Biology
(Springer International Publishing, 2016)
South Africa has severe problems caused by biological invasions in terrestrial, freshwater and marine ecosystems, and a long history of managing biological invasions. However, appreciation and systematic study of the ...
The structure of the littoral: effects of waterlily density and perch predation on sediment and plant-associated macroinvertebrate communities
(John Wiley & Sons Ltd, 2016)
1. Littoral zones are complex and important for mechanisms that maintain clear water and submerged plant dominance in lakes. Details of their structure are scarce, largely because sweep or grab sampling, the most commonly ...
Soil biota in a megadiverse country: Current knowledge and future research directions in South Africa
(Elsevier GmbH, 2016)
Soils are integral to agricultural productivity, biodiversity, and the maintenance of ecosystem services. However, soil ecosystem research depends on foundational biological knowledge that is often missing. In this review, ...
Historical perspectives on global exports and research of African clawed frogs (Xenopus laevis)
(Taylor & Francis, 2016)
Trade in live animals has been associated with populations of invasive species as well as the spread of disease. The African clawed frog, Xenopus laevis, was exported from its native region of southern Africa for use in ...
Implications of summer breeding frogs from Langebaanweg, South Africa: Regional climate evolution at 5.1 mya
(Academy of Science of South Africa, 2016)
No direct palaeoclimatic proxies have been available to indicate the seasonality or amount of rainfall on the west coast of southern Africa during the Early Pliocene. The Benguela Upwelling System (BUS) is today one of ...
Diving in head first: trade-offs between phenotypic traits and sand-diving predator escape strategy in Meroles desert lizards
(The Linnean Society of London, 2016)
Survival, in part, depends on an individual’s ability to evade predators. In desert regions some lizard species have evolved head-first sand-diving strategies to escape predators. To facilitate this behaviour, a distinctive ...
Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy
(Natural History Museum, 2016)
Frogs are the most species-rich and ecologically diverse group of amphibians and are characterized by a unique body plan including long legs, elongated ilia, and fused caudal vertebrae. Stem anurans such as Triadobatrachus ...
Impacts of climate change on the global invasion potential of the African clawed frog Xenopus laevis
(Public Library of Science, 2016)
By altering or eliminating delicate ecological relationships, non-indigenous species are considered a major threat to biodiversity, as well as a driver of environmental change. Global climate change affects ecosystems and ...
Controlling the African clawed frog Xenopus laevis to conserve the Cape platanna Xenopus gilli in South Africa
A five year control programme of the African clawed frog Xenopus laevis resulted in improved population demographics in the Cape platanna Xenopus gilli in comparison to a population without removal.
