Population Conservation Demography
flagship species
Charismatic species that attract attention to losses in an ecosystem are called
ex situ conservation
Conservation using a refuge to prevent imminent extinction in zoos and aquariums
nature reserves and wilderness area
Protected areas with the goal of maintaining habitat areas in pristine, natural condition
patch
A discrete, homogeneous habitat that differs from the surrounding matrix
analyzing results and drawing conclusions
In addition to observation, development of a hypothesis and experimentation, the scientific method includes
umbrella species
Species whose protection of their habitat also protects species within the same ecosystem are known as
soft release
Translocations and captive bred animals maintained in enclosures to acclimate to habitat
marine protected areas
Areas of the ocean that are important as refugia, nursery, and population re-stocking sources
landscape
A heterogeneous mosaic of habitat patches
treatment variable
The variable that is being tested compared to a control to determine an effect
disease, resource competition, predation, stress
Factors that increase with increasing population density
what are puffins, red wolf, Iberian lynx
Animals that have experienced successful re-introductions
habitat/species management areas
Protected areas that typically require monitoring and intervention to maintain biodiversity, such as the manipulation of forest structure for the ruffed grouse
corridors
Areas that connect patches that can provide additional habitat
the median
The middle data value in a list of sorted data in a data set
effective population size
The number of breeding individuals in the population, contributing genes into the next generation
capture, mark, recapture
The method of field sampling, placing a permanent mark and releasing individuals, then re-sampling
biodiversity hotspots
Protected areas characterized by a high level of species richness, some with a high number of endemic species
an ecotone
A transition area between two connected ecosystems/habitat types
null hypothesis
A hypothesis that states there is no statistically significant difference between two conditions
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
stakeholders
Conservation personnel, people from local communities, politicians, and businesses with an interest in a protected area
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
