EXAM 2 (RANDAL
BOON)


Spacial Structure - CORRECT REPLY>>>>>>-The pattern of
desity and pacing of individuals in a population



Fundamental niche - CORRECT REPLY>>>>>>-The range of
abiotic conditions under which a species can persist



realized niche - CORRECT REPLY>>>>>>-the range of abiotic
and biotic conditions under which a species actually lives

- aids in species conservation and can limit spread of invasive
species

,Geographic range - CORRECT REPLY>>>>>>-the geographic
boundary in which a species can exist



Distribution of populations - CORRECT REPLY>>>>>>-Small
scale variation in the environment creates geographic ranges
that are composed of small patches of suitable habitat

-we can test whether species are limited by unsuitable
environmental conditions

-populations can grow larger in more suitable habitats



Ecological niche modeling - CORRECT REPLY>>>>>>-The
process of determining suitable habitat conditions for a
species



Ecological envelope - CORRECT REPLY>>>>>>-The range of
ecological conditions that are PREDICTED to be suitable for an
envelope

,Modeling invasive species - CORRECT REPLY>>>>>>-
Ecological niche modeling can predict the expansion of pest
species



Effects of Global warming - CORRECT REPLY>>>>>>-
Temperature change can cause a shift in the geographic range
of a species



endemic - CORRECT REPLY>>>>>>-Species that live in a
single (often isolated) location



Cosmopolitan - CORRECT REPLY>>>>>>-Species with very
large geographic ranges that can span several continents



Abundance - CORRECT REPLY>>>>>>-The total number of
individuals in a population that exist within a defined area



Population density - CORRECT REPLY>>>>>>-number of
individuals per unit of area (abundance divided by area)

-Highest density typically occurs near the center of their
geographic range

, -density is > than habitat can support some individuals must
leave or the population will experience lower growth and
survival



Dispersion - CORRECT REPLY>>>>>>-The spacing of
individuals with respect to one another



Clustered dispersion - CORRECT REPLY>>>>>>-When
individuals are aggregated in discrete groups



Evenly spaced dispersion - CORRECT REPLY>>>>>>-When
individuals maintains an uniform distance between itself and
its neighbors



Random dispersion - CORRECT REPLY>>>>>>-When the
position of each individual is random to others, not common
due to environmental heterogeneity



Population Dispersal - CORRECT REPLY>>>>>>-The
movement of individuals from one are to another
