ECOL111: Population Ecology Questions with Answers
(100% Correct Answers)
Open Population Answer: a population that is not geographically
isolated, therefore can lose to/gain from different populations.
Closed Population Answer: a population that's abundance is fixed
(except via birth and death), as no members will be added/lost to
different populations.
Local distribution Answer: distribution of a species in a local area.
Dispersed Answer: a ecological process that involves the movement of
an individual or group away from their birth population.
Over dispersed Answer: large quantities of a population disperse from
the original population, patterns in dispersion tend to occur across a
landscape.
Contagious clumped Answer: organisms in a species are clumped
together, and their distribution is reliant on their proximity to each
other.

Aggregation Answer: a group of animals that is independently formed
because individuals are attracted to an environmental resource in the
area that is important for functioning.
Geological distribution Answer: distribution of a species globally.
Uses for population abundance data Answer: estimating a populations
probability of survival, estimating sustainable harvest, understanding
populations nature, accessing spread of pests, calculating needs of a
managed population.
Purposes for estimating probability of population survival Answer:
finding annual variation in populations and finding maximum yield.
Exclusive Economic Zones Answer: an area of the ocean that generally
extends 200 nautical miles (230miles) beyond a nations territorial sea,
within these zones countries have jurisdiction over both living and
non-living resources.
Methods for population abundance estimates Answer: tag recapture,
surveys, counts per unit time (trappings + photos), remote sensing,
proxies (songs, prints, scat).
