German scientists assessed the impacts of climate change for the global distribution of the African clawed frog Xenopus laevis in collaboration with an international team. With the help of mathematical models the research found that the current populations in Europe will increase driven by the projected impact of climate change. The study was noe published in the renowned journal PLoS One.
Native to southern Africa, the species is a popular model organism for laboratory research and was distributed to laboratories worldwide. A popular use of the frog was pregnancy testing. African clawed frogs act as a vector of the amphibian diseases chytridiomycosis and ranavirus, which has caused global declines in amphibian populations. Being generalist predators which may occur in high densities the species has significant impacts on the local fauna.
“Meanwhile, populations have become established in the wild across four continents and the species is still spreading” explains Flora Ihlow, PhD student at the herpetology section of the Zoological Research Museum Alexander Koenig – Leibniz-Institute for Animal Biodiversity (ZFMK) in Bonn. “In Europe alone, viable populations presently exist in France, Portugal, and Sicily” Ihlow explains. Using modern species distribution modelling techniques, the scientists revealed that climate change will likely reduce the species’ global spread. These results have recently been published in the renowned scientific journal PLoS One.
“While we expect the species’ distribution potential to decrease on a global scale in response to climate change, our models predict the novel climatic conditions to favour expansions along the northern range limits” explains Dr. Dennis Rödder, curator of the herpetology section of the ZFMK. Therefore, Rödder says “the altered climatic conditions may promote new invasions and range expansions in Europe”.
„The combination of field data with computer-generated, spatial explicit simulations is the main strength of the EU supported BiodivERsA project. These detailed predictions on the potential future distribution of invasive species facilitate the coordination of suitable counteractive measures“, explains Prof. Dr. Wolfgang Wägele, director of the ZFMK.

Zoological Research Museum Alexander Koenig – Leibniz-Institute for Animal Biodiversity (ZFMK) is an independent research institute. The focus of research is on performing an inventory of the zoological species diversity on earth, on the analysis of changes in biodiversity as a result of environmental factors, and on evolutionary processes at the morphological and molecular levels. ZFMK furthermore explores the context of structure and function of ecological systems, advanced scientific methods, and the study of the history of science. The permanent exhibition “Our blue planet – the living network” offers a genuine nature experience based on naturalistic ecosystem displays.
The Leibniz Association is a network of 88 scientifically, legally, and economically independent research institutes and scientific service facilities. Leibniz Institutes perform strategic and thematically-oriented research and offer scientific service of national significance while striving to find scientific solutions for major social challenges.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
