Ecology and the Environment

Survival of the fittest isn't always a tried and true concept, especially when invasive species are involved. When an organism equipped for one environment is introduced to another that doesn't have natural predators, it's often a formula for disaster. Humans, both intentionally and unintentionally, transport species to areas where they can become invasive. And with our recent travel habits, the pet trade and the global economy, it's easy to see how these guys end up on foreign soil. In fact, you might be housing an invasive species in your house or backyard. See how many intrusive creatures you recognize in the Ultimate Invasive Species Quiz.
