Cards

Term
gyrus
Definition
bump. the more bumps the better. complexity of the diet- more restricted diet affect brain size. leaf eaters have smaller brain then fruit eaters.
Term
nerves on primitive primates
Definition
come out between the eyes
Term
nerves in higher primates
Definition
come from behind the eyes. fewer nerves.
Term
jacobsons organ
Definition
chemosensor in roof of mouth. senses hormones in ex urine.
Term
post orbital bar
Definition
the bar where the eye socket ends (lower primates)
Term
nocturnal animals
Definition
typically have either increased smell or larger eyes.
Term
rods
Definition
for light, no color
Term
cones
Definition
color vision
Term
hearing
Definition
three parts: outer, middle, inner
inner ear is simply used for balance
Term
k-selection
Definition
few offspring, high investment in offspring--like humans
Term
r-selected
Definition
lots of offspring, low investment
Term
long childhood period
Definition
for learning
Term
primate growth
Definition
is rapid after birth. most mammals slow down.
Term
menopause is an adaptation
Definition
grandmother hypothesis- menopause is to help women in the raising of grandchildren
Term
primate adolescence in fossils
Definition
dental eruption rates in extant primates. you must have a sample size. Neanderthals matured faster than we do.
Term
primate habitat
Definition
where animals live (address), divided into biomes
Term
primate niche
Definition
includes the habitat, ecological role in the environment, profession
Term
profession
Definition
all factors contributing to an animals survival
Term
factors
Definition
food, predators, home, activity patterns
Term
no two species
Definition
can occupy the same niche. competition
Term
Biomes
Definition
divsions of primates habitat. broadly similar vegetation.
Term
4 structural divisions
Definition
1. forest
2. woodlands
3. savanna
4. desert/semi desert
Term
forests
Definition
tall trees dominate, canopies often present
Term
primary:
Definition
high trees emergents 80m; continuous canopy; dark open understory
Term
secondary
Definition
primary forests is cut down. fast growing. can be primary again. species poor. more light (understory more dense w/ vegetation. shorter trees
Term
other types of elevation
Definition
montane, high and lowland, swamp, bamboo
Term
Forest structure, plant types affected by:
Definition
soil type, heat, precipitation, seasonality, elevation, bedrock
Term
woodlands
Definition
shorter, deciduous trees, grasses, bushlands, canopies not as dense
Term
savanna
Definition
few trees, many grasses, gallery forests line rivers in dry areas, major predators on savanna
Term
desert/semi desert
Definition
sparse, low growing shrubs. little vegetation.
Term
primates live on
Definition
5/7 continents. no native ones in antartica and austrailia.
Term
primates typically live in
Definition
tropical climates, tropical forests, focused on areas around the equator
Term
____ affects where primates live
Definition
height; tops of tree/bottom/middle
Term
climates at different heights
ground:
Definition
less light
more vertical supports
more terrestrial predators
Term
climates in the canopy
Definition
more horizontal, continuous supports
more fruits, leaves
Term
emergents climates
Definition
more avians predators
more light-higher temp
less continuous supports
Term
why dont they all live in the canopy?
Definition
cause of niche overlap--competition
Term
primates are not in a vacuum
Definition
all evolve together: plant defenses, plant encouragement, competition with other species, prey predators
