This course focuses on terrestrial and aquatic habitats for organisms.  For terrestrial habitats, the major biomes (e.g. tropical rain forests, taiga, savannah, desert) will be discussed in relation to the influence of major environmental factors. Community development discussions will focus on concepts such as succession, climax, species diversity and productivity. The course also looks at major aquatic communities (i.e. neuston, plankton, nekton and benthos), environmental factors and their roles in aquatic ecosystems, and the ecological classification of aquatic organisms.
