- Global Distribution of Wildlife
- Biodiversity: the variability among living organisms from all sources inc terrestrial marine and other aquatic ecosystems and the ecological complexes of which they are part of.
- Biodiversity tends to be rich where it is hot and wet.
- Hadley Cell
- 1. Hot air rises. 2. Cool air rises and drops moisture 3. Cooler air moves North and South
- Climate change: Dessert moves north. Prevents species from being able to relocate.
- As you move away from equator biodiversity decreases.
- Biodiversity is greater in lower latitude
- Biodiversity is high in tropics and coral reefs.
- Seasonality affects biodiversity: organisms can move and adapt to the changing seasons
- Biodiversity hotspots: Mediterranean and Wallacia line
- Hadley Cell
- Biodiversity tends to be rich where it is hot and wet.
- Biogeography: study of geographical patterns of plants and animals
- Ecology: study of interactions amongst organisms.
- Ecological Hierarchy: Biosphere, Biome, Landscape, Ecosystem, Biotic Community, Population, Organism.
- Taxonomic: Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Physiological: Organism, organ system, organ, tissue, cell, organelle, molecule.
- When ecosystems are measure in functional diversity (takes into account amount of species and what they eat) latitude ceases to be a major factor in biological richness.
- Definitions:
- Ecosystem - living and non-living in a certain area living together.
- Biome - type of environment
- Habitat - where an organism lives
- Community: living components living in the same place at the same time.
- Land cover: vegetation in a given area.
- Land use: what use is made of that land.
- Tolerance: species being able to adapt and tolerate conditions
- Ecological niche: the species that live in a particular environment
- Liebigs law of minimum
- Total yield of any organism is determined by resource present in lowest concentration in relation to requirements of that organism.
- Shelfords law of tolerance
- Too much of something can impair growth and lead to death. Any organism has a range of tolerance for any factor
- Biodiversity: the variability among living organisms from all sources inc terrestrial marine and other aquatic ecosystems and the ecological complexes of which they are part of.
