Applied Population Biology

what kind of information is used for PVA

• average mortality rate

• average recruitment rate

• current age or size distribution

if birth rate is 0.5, that means an individual has a ___ change of reproducing that year

50%

number of individuals of a species required for persistence over time

minimum viable population (MVP)

how is MVA calculated

via PVA

“a population of populations” - spatially separated interacting populations

metapopulations

sink populations, which may become extinct in unfavorable years and recolonized from care populations, are also known as

satellite populations

source populations, that exports individuals, are also known as

core populations

metapopulation examples

Bighorn sheep - use meta-population dynamics to maintain dispersal and gene flow which helps preserve immunogenetics diversity and resistance

examples of ecosystem processes

temperature, rainfall, humidify, soil acidity, water quality, etc.

species present, percentage of vegetative cover, amount of biomass at each trpohic level

community characteristics
