In protecting and managing a rare or endangered species it is vital to have a firm grasp of : pg 273
|
the ecology of the species,
distinctive characteristics (natural history), status of the populations, dynamic processes that affect population size and distribution (population biology) |
|
Census pg 280
|
count of the number of individuals present in a populations
|
|
survey pg 282
|
population involves using a repeatable sampling methods to estimate the number of individuals or the density of a species in a part of a community
|
|
demographic studies pg 283
|
follow known individuals of different ages and sizes in a populations to determine their rates of growth reproduction and survival
|
|
population viability analyis (PVA) pg 285
|
prediction of whether a species has the ability to persist in an environment , can be used in considering the effects of habitat loss, habitat fragmentation, and habitat deterioration on a rare species; also for management
|
|
metapopulation pg 287
|
is made up of a shifting mosaic of populations linked by some degree of migration
|
|
source population pg 288
|
core population with fairly stable numbers
|
|
sink populations pg 288
|
satellite populations fluctuate with arrivals of immigrants
|
|
natural history covers: pg 293
|
environment, distribution, biotic interaction, morphology, physiology demography, behavior, genetics, and interactiions with people
|
|
PVA- population viability analysis- uses pg 293
|
demographics, genetic, environmental, and natural-catastrophe data to estimate the probability of population's persisting in an environment to some future data
|
|
ephemeral habitat pg 293
|
short lived, seasonal; characterized by meta populations made up of shifting mosaics of temporary populations that are linked by some degree of migration
|
|
long term monitoring efforts pg 293
|
provide an early warning systems for threats to species, communities, ecosystem functions, and human communities
|
|
population biology pg 272
|
status of population,particularly the dynamic process that affect population size and distribution
