|
Ecology
|
the study of an organisms interaction with the biotic and abiotic factors in its environment
|
|
|
Organismal Ecology
|
how does an organism relate to its environment
|
|
|
Population Ecology
|
reproduction
|
|
|
Community Ecology
|
givven area of interaction of different species
|
|
|
Ecosystem Ecology
|
biotic and abiotic factors
|
|
|
Landscape Ecology
|
how things interact across ecosystem boundaries
|
|
|
Biogeographic Realms
|
Neartic
Neotropical Ethiopian Australian Oriental Paleartic |
|
|
Biogeographic Realms
|
areas where organisms are similar because they share an ecology and evolutionary history
|
|
|
Biome
|
an area with similar climate and vegetation (shape and density) either terrestrial or aquatic
|
|
|
Wetland
|
an area with sufficient water cover (standing water) to support aquatic plants
|
|
|
Rivers and Streams
|
flowing water
dependent on an outside source of biomass |
|
|
Estuary
|
where a freshwater river meets a body of saltwater
|
|
|
Coral Reefs
|
substrate is built from living organisms
|
|
|
Pelagic
|
open waters
|
|
|
Benthic
|
deep water
|
|
|
Terrestrial Biomes
|
primary production via photosynthesis
sunlight and precipitation are important factors of photosynthesis |
|
|
Tropical Forrest
|
(jungle) 25-29 C
200-400 cm precip/yr= rain forest 150-200 cm precip/yr= dry forest |
|
|
Desert
|
near 30 degrees latitude
precip < 30 cm/yr temp > 50C to < -30C temp varies because there is no moisture in the air to hold heat |
|
|
Savannah
|
grassland with some trees
sub equitorial precip 30-50 cm temperature 24-29C |
|
|
Chapparal
|
mid-latitude along the coast only
seasonal precip 30-50 cm (winter or late fall) temperature 10-12C winter, 30C summer |
|
|
Temperate Grasslands
|
interior mid-latitude
seasonal precipitation (30-100cm *summer*) temp -10C winter, 30C summer extreme temp fluxation makes it unable to grow trees maintained by fires |
|
|
Temperate Broadleaf Forest
|
70-200 cm/year of precip
constant rain fall temp 0C-30C trees drop leaves so that the cell wall does not freeze and therefore rupture |
|
|
Borreal Forest
|
(Taiga)
precip 30-70cm (winter) temp -70C-30C round leaves (needles) so they do not expose thier leaves to as much freezing temp. must photosynthesize year round largest forest |
|
|
Derived Human Characters
|
upright gait (bipedalism)
large brain reduced jawbone short digestive tract FORAMEN MAGNUM |
|
|
Retina Structure
|
color vision
depth perception rods- light vs. dark cones- color vision Humans and old world primates have tri-color vision (blue, green and red) |
