Document Summary
Conservation biology (cid:149) study of human impacts on organisms (cid:149) development of ways to protect biodiversity: two techniques to preserve biodiversity. In-situ conservation :preserving biodiversity in nature, on site conservation (protecting or rehabilitating large areas of habitat/ restoring degraded ecosystems. Ex situ conservation: conserving biodiversity in human-controlled settings, captive breeding programs in zoos, aquaria, aviaries, botanical gardens and/ or gene banks. Conserving species (cid:149) zoos, aquaria, botanical gardens (cid:149) collecting eggs, seeds (cid:149) captive breeding: expensive, difficult, may not work. Seed banks (cid:149) seed collections (cid:149) 100 + worldwide (cid:149) norway capacity for 4. 5 million samples (currently 890,000) (cid:149) kept at low temperature (cid:149) disadvantages: some cannot be stored, expensive, stopping natural selection. Opportunities for scientific studies, public education, selective mating to maximize genetic variability (when small genetic pool, don"t want them to just mate within their pool since may be related = bad) (cid:149) example: pandas.
