Miniature Guttural Toads on Mauritius and Réunion stun researchers

Researchers from the DSI/NRF Centre for Invasion Biology at Stellenbosch University have found that, scarcely a hundred years after Guttural Toads were introduced to the islands of Mauritius and Réunion, their overall body size has been reduced by up to a third compared to their counterparts in South Africa.

What can we learn about predicting impacts of alien predators from a globally invasive crab?

Because resources for addressing environmental problems are limited, it has been suggested that management should focus on those species that have the highest impacts in their new environments. Comparing the ability of alien and native species to utilize resources has been shown to offer a sound approach for identifying alien species with high impacts.
