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
In addition to observation, development of a hypothesis and experimentation, the scientific method includes
analyzing results and drawing conclusions
Species whose protection of their habitat also protects species within the same ecosystem are known as
umbrella species
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
The variable that is being tested compared to a control to determine an effect is the
treatment variable
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
Areas that connect patches that can provide additional habitat are
corridors
The middle data value in a list of sorted data in a data set is the
median
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
A hypothesis that states there is no statistically significant difference between two conditions is a
null hypothesis
Captive breeding of wild species is not a viable long term solution due to
inbreeding, a need to preserve habitat, and need for an ecological niche for species reintroduction
Parameters needed to construct a Population Viability Analysis (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
A calculated p value that is less than 0.05 indicates
a significant effect or difference among variables that were tested
