Establishing New Populations Flashcards
What program releases captive-bred or wild-collected individuals at an ecologically suitable site withing their historical range where the species no longer occurs?
reintroduction program
What program involves releasing individuals into an existing population to increase its size an/or gene pool to adjust age or sex structures
Reinforcement program
What program involves moving captive-bred or wild-collected animals or plants to areas suitable for the species outside their historical range?
introduction program
What are three considerations that should be thought of when there is a translocation happening?
Genetics, human concerns, is it controllable, ecology of species
Explain soft release in your own words
Soft release is when there is assistance/care given to the organisms post release (shelter, feeding)
Explain hard release in your own words
Hard release is when there is no assistance post release, and they are more common than soft.
What field study an animal’s behavior in the context of its environment and considers the adaptive significance of those behaviors
Behavioral Ecology
What are the “special” considerations when it comes to the translocation of species?
Behavioral ecology, foraging, social, and antipredator
What does PVA stand for and what does it do?
Population viability analysis; determine best practices for plant reintroduction
What is ex-situ conservation in your own words?
this type of conservation is off site conservation such as zoos, captive breeding centers, aquariums, botanical gardens, etc.
What are some benefits of ex-situ conservation?
Benefits: opportunity for research, restore populations, can “buy time”
When Pygmy rabbits had poor ex situ reproductive success, the use of natural habitats with predator exclusion fences were used in order for them to be able to reproduce, why would this be different than a soft release approach?
This would be different than a soft release approach because there is little to no human interaction, they are not being forced to mate and once they have a suitable number they are reintroduced back into the wild by hard release.
What are the 3 different types of captive breeding and tech used?
cross fostering, artificial incubation, embryo transfer, and genome banking
What are the 3 strategies when it comes to de-extinction?
Back-breeding, cloning, genome reconstruction
