INVAXEN Project: Invasive Biology of the African Clawed Frog in Europe

The video discusses the INVAXEN project, which focuses on the invasive biology of the African clawed frog (Xenopus laevis) in Europe. Below are the key scientific concepts and findings presented.

Invasive Alien Species and Biodiversity Threats

The African clawed frog, native to Southern Africa, is a highly invasive amphibian species that has spread to four other continents. This spread is primarily due to escapes and releases from laboratories and the pet trade. The species poses significant threats to biodiversity by:

Competing with native species
Preying on native species

Adaptability and Impact in Europe

This frog exhibits high adaptability to certain European climates, which enables:

Rapid reproduction
Fast spread across ecosystems

These factors contribute to negative impacts on native European ecosystems.

Multidisciplinary Research Approach

The INVAXEN project brought together scientists from four European countries and South Africa to study the frog’s biology and behavior through:

Ecological data analysis
Physiological studies
Genetic investigations

Distribution Mapping and Prediction

Using satellite imagery combined with ecological data, the research team was able to:

Accurately define the current distribution of the African clawed frog in Europe
Predict its potential future range

Collaboration with Stakeholders for Conservation

INVAXEN worked closely with local environmental agencies and landowners to implement conservation actions, including:

Improving frog capture methods in ponds using electrofishing
Encouraging pond drainage to reduce breeding sites

Application of Research in Management Projects

The LIFE project CROAA utilized INVAXEN’s predictive models to:

Identify zones at risk of invasion
Enable targeted preventive measures to curb the frog’s spread

Outcome and Significance

The project demonstrated that evidence-based scientific research can effectively guide conservation practitioners in:

Preventing biodiversity loss
Protecting native species and ecosystems
