Conserving Populations Flashcards
Conservation can only be effective with a strong understanding of the natural history and population biology of a species, what are some examples of these?
distribution, morphology, behavior
What is the natural history of organisms only investigable with what?
field work
What could population monitoring field work look like?
tree measurements, macro invert surveys, plant transects
What are some outcomes and goals of field work?
identify trends, conservation action, measuring ecosystem health, “providing a witness”
What term is described as the minimum populations size that would have a 99% chance of remaining extant for 1000 years - despite genetic, environment, and demographic stochasity
minimum viable population (MVP)
What term is described as how much spaced the MVP requires
Minimum dynamic area (MDA)
What type of population is able to hold more individuals, the individuals are doing well, and they send out their individuals to breed
core population
What term is described as a situation in which individuals are coming from a core population to mate, but there isn’t a gene flow back, and their population tends to go extinct
sink population
What are the three types of populations that are most likely to gets conserved first?
critically endangered, endangered, and vulnerable
What type of approach deals with keystone species?
species approach
What type of approach deals with a self maintaining ecosystem?
ecosystem approach
What type of approach deals with the most numbered species for the same amount of money?
hotspot approach
Explain the difference between an indicator and a flagship
an indicator gives an idea of how healthy an ecosystem is, an indicator doesn’t do necessarily the same but it brings a lot of attention to the public eye
What does DUE stand for?
Distinctiveness, Utility, and Endangerment
What term is defined as a place that encompasses the diversity of species and conditions characteristic of that ecosystem
representative site
