How repeatable is the Environmental Impact Classification of Alien Taxa (EICAT)? Comparing independent global impact assessments of amphibians
(Wiley Open Access, 2017)
The magnitude of impacts some alien species cause to native environments makes them targets for regulation and management. However, which species to target is not always clear, and comparisons of a wide variety of impacts ...
Population genetics of the Sao Tome caecilian (gymnophiona: dermophiidae: schistometopum thomense) reveals strong geographic structuring
(Public Library of Science, 2014)
Islands provide exciting opportunities for exploring ecological and evolutionary mechanisms. The oceanic island of São Tomé in the Gulf of Guinea exhibits high diversity of fauna including the endemic caecilian amphibian, ...
Counting chirps : acoustic monitoring of cryptic frogs
(Wiley, 2016)
This study explores the utility of monitoring using acoustic spatially explicit capture–
recapture (aSCR) with time of arrival (ToA) and signal strength (SS) as a quantitative monitoring
technique to measure call density ...
Frog eat frog : exploring variables influencing anurophagy
(PeerJ, 2015)
Background - Frogs are generalist predators of a wide range of typically small prey
items. But descriptions of dietary items regularly include other anurans, such
that frogs are considered to be among the most important ...
Shell crushing resistance of alien and native thiarid gastropods to predatory crabs in South Africa
(Regional Euro-Asian Biological Invasions Centre, 2016)
The successful invasion of freshwater and coastal lakes of South Africa by the recently introduced thiarid snail Tarebia granifera may be due in part
to release from predatory pressure. This study aimed to determine the ...
Implications of summer breeding frogs from Langebaanweg, South Africa : regional climate evolution at 5.1 mya
(Academy of Science of South Africa, 2016-09-28)
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 ...
Distribution and establishment of the alien Australian redclaw crayfish, Cherax quadricarinatus, in South Africa and Swaziland
(PeerJ, 2017)
Background
The Australian redclaw crayfish (Cherax quadricarinatus, von Martens), is native to Australasia, but has been widely translocated around the world due to aquaculture and aquarium trade. Mostly as a result of ...
Implications of summer breeding frogs from Langebaanweg, South Africa : regional climate evolution at 5.1 mya
(Academy of Science of South Africa, 2016-05)
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 the ...
Sequential fragmentation of Pleistocene forests in an East Africa biodiversity hotspot : chameleons as a model to track forest history
(Public Library of Science, 2011-10-28)
Background
The Eastern Arc Mountains (EAM) is an example of naturally fragmented tropical forests, which contain one of the highest known concentrations of endemic plants and vertebrates. Numerous paleo-climatic studies ...
Impacts of climate change on the global invasion potential of the African clawed frog xenopus laevis
(Public Library of Science, 2016-06-01)
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 ...
