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
