摘要: Abstract In South Africa, a plan was launched to manage separate sub-populations of endangered African wild dogs ( Lycaon pictus ) in several small, geographically isolated conservation areas as single meta-population. This intensive management approach involves the re-introduction into suitable and periodic translocations among them. Despite initial failures high costs associated with dog re-introductions translocations, there is no predictive framework available quantify which protocol most efficient. We therefore developed an individual-based model population pack dynamics, accounts for dogs’ social complexity. The appeared capture essential characteristics real from Hluhluwe-iMfolozi Park, Africa be relatively robust parameter uncertainty, suggesting that valid enough addressing problems. enabled us critical number packs (two) individuals per (six) necessary re-introduced establish itself release area. also found practically feasible intervention regime at had best chance persistence: intermittently adding (at least every 6 years) harvesting disperser groups (as often 4 years) translocation other sites, without threatening small source population. study demonstrates models can powerful decision-support tool planning provides insight how populations made up have ultimately persistence, determined by individual behaviour.
