Understanding different types of uncertainty in invasion science is crucial for effective management

Uncertainty is part and parcel of any scientific field. The point of scientific research is to acquire knowledge and to deal with different types of uncertainty to improve our understanding of natural phenomena and help us make projections about the future.

Protected areas defend wildlife from invasive alien species
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.

Protected areas defend wildlife from invasive alien species

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.

Parasites as drivers and passengers of biological invasions
A classic example of a parasite influencing an invasion is the replacement of the red squirrel (Sciurus vulgaris) by the grey (S. carolinensis) in the UK. The invasion of the grey and severe population decline of the red has been mediated at least in part by parapoxvirus introduced from North America along with the grey squirrels.

Parasites as drivers and passengers of biological invasions

Alien species are a common sight around the world. Yet, the diversity and ubiquity of these species belies the fact that many alien introductions fail to take hold.

Comparing impacts of alien plants and animals using a standard scoring system

Knowing which species to manage amongst all the species introduced outside of their native ranges is a huge challenge. Many factors play a role in the decision making process, one of the most important ones being whether or not the alien species causes harm to native ecosystems and species, or damages the economy.
