|
An extinction vortex
|
|
|
T/F: Small populations can experience inbreeding and lack of genetic diversity which can lead to evolutionary death, but some small populations can seem to be also unaffected by this.
|
True
|
|
|
What is the "minimum viable population"?
|
The minimal population size at which a species is able to sustain its numbers and survive
|
|
|
What is the effective population size?
|
The number of members of the population that are actually capable of reproducing and furthering the species
|
|
|
T/F: Most population conservation goals aim to keep the effective population size (Ne) above the MVP.
|
True
|
|
|
T/F: The declining population approach focuses on animals that are exhibiting a downward trend in population, even if their numbers are above the MVP (minimum viable population).
|
True
|
|
|
What is the main difference between the small and declining population approaches?
|
Small focuses on increasing genetic variability, while declining focuses on the environmental factors that made it begin to decline
