Invasionsbiologi

Invasionsbiologi is the scientific study of biological invasions. It focuses on understanding the processes by which alien species spread to new regions and establish themselves, as well as their impacts on native ecosystems and biodiversity. A biological invasion occurs when a species, often facilitated by human activity, is introduced into a new environment where it was not previously found and thrives, potentially causing ecological or economic harm.

Key areas of research in invasionsbiologi include the pathways of introduction, such as trade, tourism, and accidental transport, and the traits that make certain species more likely to become invasive. Scientists also investigate the ecological mechanisms that facilitate or hinder invasion success, such as competition, predation, and habitat alteration. Furthermore, the field examines the consequences of invasions, including changes in species composition, food webs, ecosystem functions, and the potential for genetic interactions with native species.

Understanding biological invasions is crucial for developing effective management and prevention strategies. This involves identifying high-risk species and pathways, implementing control measures for established invasive populations, and restoring invaded habitats. Invasionsbiologi contributes to conservation efforts by providing the scientific basis for protecting biodiversity and maintaining ecosystem health in the face of global change.
