final test Flashcards
Biogeography
study of organisms both past and present
Historical Biogeography
reconstruction of the origin, dispersal, and extinction of various taxa
Ecological Biogeography
study of the present distribution of life and the interaction between the organism and the environment
Sir Joseph Banks
known for the natural sciences
Johannas Warming
early plant biogeographer, plant ecology
Turnover Rate
the rate at which one species is lost and a replacement gained
Rescue Effect
extinction of a dwindling population may be slowed or halted by an influx of immigrants
Landscape Mosaic
different types of land cover, clusters of local communities repeated in a similar manner over a wide area
Ecotone
the transition zone where one vegetation patch blends with another
Corridors
strips of vegetation linking one patch with another on the landscape
Ecoregions
major ecosystems that result from predictable patterns of climate as influenced by latitude, global position, and altitude

described the life zones of a mountain environment, relationship between climate and vegetation
Endemic

when the surface gets colder, 4 degrees Celcius, it will sink and mix
Shredders
invertebrates that feed on leaves and other large organic particles
Collectors
filter feeders

feed on the algal coatings of stones and rubble
Infauna
animals that can burrow into the sand
Estuaries
semi-enclosed areas where fresh water and seawater meet and mix
Mangroves
a shrub or tree that grows in coastal saline or brackish water (nursery ground for fish)
