Document Summary
Ecology: the study of how organisms interact with their environment, goal to understand the distribution and abundance of organisms. Key concepts: ecology"s goal is to explain the distribution and abundance of organisms. It is the branch of biology that provides a scientific foundation for conservation efforts: physical structure particularly water depth is the primary factor that limits the distribution and abundance of aquatic species. Climate is changing rapidly around the globe: a species" distribution is constrained by historical and biotic factors, as well as by abiotic factors such as physical structure and climate. 4 main levels of ecology: organismal ecology. Explore the morphological, physiological and behavioural adaptations that allow individuals to live in a particular area. Salmon migrate from saltwater to freshwater environments to breed: population ecology. Focus on how the numbers of individuals in a population change over time. Each female salmon produces thousands of eggs but only a few will survive to adulthood: community ecology.
