Ecosystems & Biogeography
How are species influenced by their environment? How do species influence their environment? These are some of the fundamental questions at the core of ecology. The field of biogeography works to understand the factors influencing the distribution and abundance of species, including temperature, disturbance regimes, species interactions, depth, and sediment type. Living organisms, however, also alter their environment, changing nutrient and chemical cycles, altering sediment transport, and otherwise interacting with the other living and non-living components of the ecosystem. Ecosystem ecology studies the complex and fascinating feedbacks between organisms and their environment.
