Document Summary
Lecture 1: an introduction to ecology and the biosphere. Ecology is the scientific study of the interactions between organisms and their environments. These interactions occur at a hierarchy of scales that ecologists study, from organismal to global. Organismal ecology is concerned with how an organism(cid:495)s structure, physiology and behaviour meet the. Population is a group of individuals of the same species living in an area. A community is a group of populations of different species in an area. A landscape, or seascape, is a mosaic of connected ecosystems. An ecosystem is the community of organisms in an area and the physical factors with which. The biosphere is the global ecosystem, the sum of all the planet(cid:495)s ecosystems and landscapes. challenges posed by its environment. Population ecology analyzes factors the affect population size and how and why it changes through tie. Community ecology examines how interactions between species, such as predation and competition, affect community structure and organization.
