Captive Breeding Management Flashcards
Define Allele
alternative form of a gene
Define diversity
number of alleles per locus
Define effective population size (Ne)
The size of a randomly mating population of
constant size with an equal sex ratio and a Poisson distribution of family
sizes that would result in the same rate of genetic drift as that observed in
the population under consideration. In its simplest form the Ne
is the
number of breeding adults in the population
Define Gene diversity (expected heterozygosity)
the heterozygosity expected if a random mating population were in hardy- Weinberg equilibrium
Define Genetic drift
Loss of alleles through random sampling of the population through Mendelian inheritance
define natural selection
The differential fitness between members of a species
possessing adaptive characteristics, and those without adaptive
characteristics
What is a Studbook?
Entire (captive) history of a population or species
includes:
- Major life history (birth, death…)
- Individual identifiers (ear tags/ microchips)
- Parentage (pedigree to founder)
Who keeps SB?
- World Association of Zoos & Aquaria
- International studbooks
- Regional zoo& aquaria associations (European (EAZA)), American, Australian..)
- Research institutions
Studbook Keeper reports to who?
EAZA Taxon Advisory Group (TAG) or WAA Conservation Coordination
What is the role of a SB keeper?
- Data compiled automatically by species360
- Collate additional data from non-member oos
-ZIMS module - Publish to studbook
How are SBs used?
- Population management (EEP)
- Identification of problem
-Research
What tools for SB keeper?
- ZIMS (zoo info management system)
- Word
- Communication tools
What is an EEP?
- European Ex-Situ Programme
- Intensive population management within a region
What is the role of an EEP coordinator ?
- Maximise genetic diversity (heterozygosity & allelic diversity)
- Equalise founder representation
- Minimise inbreeding, genetic drift & adaptation to captivity - Maintain demographic stability
- Provide animals for reintroduction, if appropriate -> breeding recommendations
What are the stages of captive breeding ?
- Founding phase
- Growth phase
- Capacity or maintenance phase
