Name: Score:97 Multiple choice questions
Term 1 of 97
Important structural features for grasslands for wildlife?
- relief from weather
- concealment for nests/breeding
- concealment or escape from predators
- concealment for predators
the killing of one species to allow the other to regain populations/numbers
- vegetation height
- density of vegetation
- percent canopy cover
- species composition (grasses v.s forbs)

Definition 2 of 97
Occurs when disproportional use of habitat types or resources are noted.
Habitat v.s niche: what is niche?
Habitat use
Habitat selection quantitative
Habitat selection may occur as a result of...
,Term 3 of 97
Define proximate factor
something that elicits a settling response from an animal
a long-term evolutionary change in species
a physical barrier preventing movement
a random behavior pattern in animals
Term 4 of 97
What are important structural features for forests for wildlife?
visual, auditory, or physical cues that come from the microhabitat, habitat patch or
landscape as a whole.
Oak trees have less room from leave to branch, leaving less room for birds to prey on bugs,
creating an increase in bug species. Whereas maple leaves have more space from leaf to
branch, creating an easier opening for birds to forage.
- morphological
- physiological
- intra/inter-specific competition
- predation
- disease/parasites
- canopy height

Simple
Easy
Difficult
Unnecessary
Definition 7 of 97
birth rates are higher than death rates
Sink habitat

Simple definition of habitat
, Term 8 of 97
Ideal-dominant (despotic) Distribution
- population measures (abundance/density, species richness/diversity)
- individual measures (condition/health/reproduction
- habitat use/selection
suitability decreases with increasing density, but not for all individuals...animals are not free
to enter any habitat (they are rules by despots...territorial)
individuals use habitat of highest quality first. as density increases in best habitat, new
individuals begin to settle in habitats of next highest quality, etc.
- not all studies find a relationship, other factors are important too
- less true for habitats of lower stature (like horizontal patchiness)
- difficult to measure
Term 9 of 97
Who are considered biotic bulldozers?
Wolves - they hunt in packs
Beavers - they build dams
Elephants - they heavily influence their environment
Bison - they graze in herds
