Extractions: BIOMES - Major Ecosystems of the World WORLD DISTRIBUTION OF BIOMES, ECOSYSTEMS, SPECIES BIOGEOGRAPHY - the study of the distribution of species BIOMES are the largest discernible subdivision of the biosphere with similar life forms (deserts, grassland, rainforest, etc.); it is a kind of ecosystem that can span continents. Biome boundaries of North America Biome boundaries of the World Biome boundaries and life forms that are present are determined by climate. Climate is the average temperature and moisture conditions present in an area. Climate influences the vegetation present ( See Fig. 7.15 or Figure B2 ). Areas with low rainfall and warm conditions are deserts; areas with high rainfall and hot conditions are rainforests; areas with low rainfall and cold conditions are tundra, etc. Similar biomes occur in different parts of the world: rainforests occur in Africa, Asia, and South America. Biomes can differentiated by the plants and animals present; they are adapted to their biome's cliamte. Rainforest plants have specific tolerance limits for high temperature and high precipitation. Desert cacti are adpated for high temperature and low precipitation. What would happen if we moved a rainforest fern to a desert or a cactus to a rainforest? Different species are present in the same biome in different parts of the world. Example: trees in the northern coniferous forest (taiga) in Canada and Russia are different species, but look similar. Species in the same biome have undergone similar evolutionary pressures.

Extractions: Home About ELC Site Map Contact Us ... Food One way of understanding differences in the ecological makeup of the earths surface is to divide it into biomes. A biome is an ecological zone whose uniformity is defined by the type of plant life that dominates within it. This makes sense for scientists because plant life will often give a strong indication of other ecological features of a zone, such as animal life and soil type. Because biomes are defined by plant life rather than region, some biomes can stretch around the world. For example, the biome known as the Boreal Forest (Boreal means northern) covers much of northern Europe, Russia, and Canada. The Boreal Forest is defined by the predominance of conifers (trees with needles, not leaves). There is more than one way to divide up the worlds biomes, but most divisions are variations on or combinations of the following commonly used categories: boreal forest (conifers), temperate forest (hardwoods or mixed hardwoods and conifers), tropical forest, desert, alpine (mountain) zone, grassland, and tundra. One commonly cited biome that doesnt easily fit within these other divisions is the chaparral or Mediterranean shrubland, which is found in European, North African, and western Asian coastal lands along the Mediterranean, as well as in coastal California. The chaparral features hardy shrub-like plants that have evolved to conserve moisture from winter rains during a long, arid summer. Biomes From MBGnet

Gather at the scheduled time near the far end of the engineering building (closest to Route 1), and from there we'll walk to Paint Branch. Long pants and old shoes would be a good idea. Check Out for the fall. Review questions are here *** IMPORTANT!!! THE EXAM WILL TAKE PLACE AS ORIGINALLY SCHEDULED ON THURS. MARCH 6!!! Therefore 211 will be cancelled for the week of March 3rd. Folks in the friday sections: We'll be starting in on exercise 1 in the lab manual this week. Please bring the manual to class, with the homework completed (p. 9). Manuals are available for purchase ($15.35) at the College Copy Center, 7319 Route 1 (It's in the basement). Please do this soon because it may be out of stock and they may need to print more. Geography 201 is an introduction to physical geography, a natural science allied with sciences such as geology, climatology, meteorology, oceanography, hydrology botany and agronomy. The geographic perspective is unique in that it integrates not only the individual systems that have commonly been associated with a single discipline, but also the interaction of these systems within a framework we call Earth System Science. The major objective of this class is to provide a fundamental understanding of the physical environment we live in. In doing so, the course will provide the basis for comprehending modern environmental issues, including those affected by human activities.

Physical factors that limit plant and animal ranges: solar energy, seasonal temperature distribution, moisture distribution, soils, topography, wind; ocean currents, light, salinity, depth/pressure. Biotic processes that limit geographic ranges (Chapter 4): niches (Hutchinson), productivity, food, predation, competition, facilitation, (Vandermeer; Werner), demography, genetics.
