Answers (100% Correct Answers) Already
Graded A+
Open Population Ans: a population that is not geographically isolated,
therefore can lose to/gain from different populations.
Closed Population Ans: a population that's abundance is fixed (except

via birth and death), as no members will be added/lost to different
populations.
Guru01 - Stuvia
Local distribution Ans: distribution of a species in a local area.
Dispersed Ans: a ecological process that involves the movement of an
individual or group away from their birth population.
Over dispersed Ans: large quantities of a population disperse from the
original population, patterns in dispersion tend to occur across a
landscape.
Contagious clumped Ans: organisms in a species are clumped together,
and their distribution is reliant on their proximity to each other.
Aggregation Ans: 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 Ans: distribution of a species globally.

Uses for population abundance data Ans: 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 Ans: finding
annual variation in populations and finding maximum yield.
Exclusive Economic Zones Ans: 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 Ans: tag recapture,
surveys, counts per unit time (trappings + photos), remote sensing,
proxies (songs, prints, scat).
Tag Recapture Ans: methods that gains access to possible whole
population estimates, and can be used on both 'open' and 'closed'
populations. This methods is also most useful for understanding species
migration/dispersal behavior.
Density estimates Ans: method is useful for gaining density estimates on
population where individuals do not move frequently.
Counts per unit time Ans: method is useful for understanding a vague
estimate on the number of individuals of a species in a general area, this
method is often used for species with individuals that move frequently.
Remote sensing Ans: often refers to satellite imaging of a conspicuous
population, or acoustic surveys that gain a general idea of marine
species distribution in a specific area in a moment.
