Study Notes
- Studbooks (SB) and Breeding Programmes (EEPs) are tools used for managing genetic and demographic data of captive populations and species.
- Studbooks record the entire history of a population or species, including major life events, individual identifiers, and parentage.
- SBs are kept by various zoo and aquaria associations, research institutions, and international organizations like WAZA.
- SB keepers collate data from member zoos, compile it into a database, and publish the studbook.
- EEPs are population management programs within a region, aiming to maximize genetic diversity, maintain demographic stability, and provide animals for reintroduction.
- EEP coordinators manage the population, set goals, and make breeding recommendations.
- Genetic changes in captivity include genetic drift and adaptation to captivity. Both processes can lead to the loss of adaptive and maladaptive alleles.
- Minimizing genetic changes is crucial for preserving animals that may one day return to the wild.
- Captive propagation phases include the founder phase, growth phase, and capacity phase, each with its unique challenges.
- Founder phase: acquiring a diverse representation of wild populations, focusing on getting more than 20 unrelated founders.
- Growth phase: minimizing the loss of founder alleles by ensuring all founders contribute equally and filling all available space as soon as possible.
- Capacity phase: addressing imbalance in founder representation by prioritizing breeding of animals with rare alleles and maintaining a minimum population size.
