Population Conservation Demography
Charismatic species that attract attention to losses in an ecosystem are called
flagship species
Conservation using a refuge to prevent imminent extinction in zoos and aquariums is known as
ex situ conservation
Protected areas with the goal of maintaining habitat areas in pristine, natural condition are designated as
nature reserves and wilderness areas
A discrete, homogeneous habitat that differs from the surrounding matrix is a
patch
Intervention to return degraded or destroyed habitats to pre-disturbance conditions is known as
habitat/ecological restoration
The pattern of population growth the slows with increasing population density is
logistic growth
Translocations and captive bred animals maintained in enclosures to acclimate to habitat is known as
soft release
Areas of the ocean that are important as refugia, nursery, and population re-stocking sources are designated as
marine protected areas
A heterogeneous mosaic of habitat patches is a
landscape
Re-establishing natural stream flow through removal of dams, planting native vegetation, and cessation of groundwater pumping is used in
riparian habitat restoration
Factors that increase with increasing population density include
disease, resource competition, predation, stress
Animals that have experienced successful re-introductions include
puffins, red wolf, Iberian lynx
Protected areas that typically require monitoring and intervention to maintain biodiversity, such as the manipulation of forest structure for the ruffed grouse are designated as
habitat/species management areas
The size, shape, composition, number, and position of patches in a landscape is the
landscape structure
Man-made structures placed in marine waters to create habitats for marine life are known as
artificial reefs
The number of breeding individuals in the population, contributing genes into the next generation is the
effective population size
The method of field sampling, placing a permanent mark and releasing individuals, then re-sampling is known as
capture, mark, recapture
Protected areas characterized by a high level of species richness, some with a high number of endemic species are known as
biodiversity hotspots
A transition area between two connected ecosystems/habitat types is known as
an ecotone
Seeding with native grasses and wildflowers and continual weeding is used in
prairie restoration
When populations become fragmented but still connected through corridors such that gene flow still occurs is a
metapopulation
Parameters needed to construct a PVA model include
current population size, age structure/reproductive potential, age specific survival, probability of stochastic effects
Conservation personnel, people from local communities, politicians, and businesses with an interest in a protected area are known as
stakeholders
When designing a reserve, a consideration typically incorporates SLOSS which stands for
single large or several small
Dredging to open a channel for tidal influx is a method used in
lagoon restoration
