The invasive grey squirrel (Sciurus carolinensis) has largely displaced the native red squirrels (Sciurus vulgaris) in the UK, and is unanimously recognised by conservationists as posing a serious threat to global ecosystems.

Nature reserves, national parks and marine protected areas have been proven to effectively shield native wildlife from the impacts of invasive species, according to a recent study in the journal Global Change Biology.

A recent paper led by C·I·B post-doctoral fellow Heidi Hirsch highlights how uncertainty about the taxonomy can impact inferences in invasion ecology, using the Australian silver wattle (Acacia dealbata) as a case study.

Understanding how changes in the climate have influenced the spread of species is important if we want to conserve our most vulnerable species. Part of the answer lies in our ability to make predictions on whether species will be able to track predicted changes in the climate.

Predicting which introduced plants and animals are likely to become invasive is a key challenge for invasion biology. To help make these predictions, scientists use models that can predict the potential spread of introduced species.
