(1 of 3)

Next to habitat destruction, invasive species are an important agent leading to loss of biodiversity. Models are useful for predicting what is happening and what could happen in a population of invasive species or species affected by them.

Zebra mussels are invasive freshwater mollusks that threaten many bodies of water they inhabit. In high numbers, they become a nuisance to other aquatic species and an indirect threat to humans. They can clog-up industrial water supplies, eliminate native species and alter aquatic food chains.
