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)
