Ecology correct answers the study of how animals interact with their environment and each other
Organismal Ecology correct answers the branch of ecology that focuses on the morphological,
physiological, and behavioral adaptations that allow an organism to live in a certain area. "How do
individuals interact with each other and their physical environment?"
Population Ecology correct answers the branch of ecology that focuses on how the number and
distribution of individuals in a population changes over time. "How and why does population size change
over space and time?"
Population correct answers a group of individuals in the same species that live in the same area at the
same time.
Community Ecology correct answers the branch of ecology that focuses on questions about the nature
of the interactions between species and the consequences of those actions. "How do species interact,
and what are the consequences?"
community correct answers populations of different species that interact with each other within a
particular area
ecosystem ecology correct answers branch of ecology that focuses on how nutrients and energy move
among organisms and through the surrounding atmosphere, soil, or water. "How do energies and
nutrients cycle through the local environment?"
ecosystem correct answers all the organisms within a given environment along with all the nonliving
characteristics.
abiotic correct answers physical and chemical, non-living components of an ecosystem.
Global ecology correct answers the young branch of ecology that focuses on how humans impact the
biosphere. "How is the biosphere affected by global changes in nutrient cycling and climate?"
biosphere correct answers thin zone surrounding the earth where life exists
Conservation biology correct answers synthesizes all 5 branches of ecology. The effort to preserve, and
restore threatened genetic diversity in populations, species diversity in communities, and and
ecosystem function.
Behavior correct answers Action-specifically, the response to a stimulus
Behavioral Ecology correct answers the study of how animals respond to certain stimuli in their
environments
, Proximate (or mechanistic) Causation correct answers explains HOW actions occur in terms of genetic,
neurological, hormonal, and skeletal/muscular mechanisms involved.
Ultimate (or evolutionary) Causation correct answers explains WHY actions occur - based on their
evolutionary consequences and history.
Territories correct answers An organism's feeding area, or any area that is actively defended, and
provides exclusive or semi-exclusive use to the owner
Intersexual selection correct answers Mate choice. The selection of an individual of one gender for
mating by an individual of another gender.
Intrasexual selection correct answers Competition within a gender to obtain mates.
Pattern and Process component of sexual selection correct answers Pattern: Selection acts on males
much more than females.
Process: Eggs are expensive, but sperms are cheap
What criteria may a female look for in a mate? correct answers a. physical characteristics that signal
male genetic quality
b. resources or parental care
c. both
Result of intense sexual selection on males correct answers Males tend to have many more traits that
are used exclusively in courtship or male-male competition.
Sexual Dimorphism correct answers any trait that differs between males and females
ecological (or environmental) selection correct answers selection that favors traits that allow organisms
to do things other than obtain mates
Altruism correct answers A behavior that has a direct fitness cost to the one performing the action and a
direct fitness benefit to the one receiving the action
Hamilton's Rule correct answers An organism will engage in altruistic behavior when Br>C
Fitness benefit is high to the recipient
Altruist and recipient are close relatives
Fitness cost is low to the altruist
Coefficient of relatedness correct answers Represented by r. Measures, by the fraction of shared alleles,
how closely the actor and beneficiary are related.
Direct Fitness correct answers fitness derived by passing on alleles via own offspring
Indirect Fitness correct answers fitness derived by helping relatives produce more offspring than they
could on their own.
