BIOGEOGRAPHY AND INVASION BIOLOGY- A THEORETICAL STUDY

Biogeography is a 19th-century discipline of geography that analyses the spatial distribution of creatures such as plants and animals. Biogeography is the scientific study, description, and documentation of the distribution and spread of species around the globe, as well as their environmental variables. Since, Invasion Invading species biology is one of the more recently created fields of biology that deals with the problem of invasive species. The phrase "invasive species" refers to plant and animal species that have been brought to new geographies and ecosystems and compete fiercely with native species that are infringing on their ecological area. They acquire and use space, soil, sunlight, nourishment, and other natural resources disproportionately, depriving native species of all available resources. They reproduce quickly and consistently, replacing native creatures. There has been transportation of species, consciously or unknowingly, since the geographical voyages, mainly during the 17th and 19th centuries. Many animals and birds migrate as a natural part of their life cycle, driven by physiological needs and environmental changes. This natural migration is not a factor in species introduction, which is mostly due to human activity.
