Monitoring movement into and through a newly planted rainforest corridor using genetic analysis of natal origin

摘要: Genetic analysis of individual origins works best with populations that are genetically distinct but which exchange a high rate immigrants, conditions don't normally coexist since immigration acts to prevent the accumulation genetic differences. We provide empirical results from newly constructed habitat linkage illustrate unique suitability such monitoring re-establishment connections between previously isolated populations. Donaghy's Corridor links 498 ha fragment rainforest an adjacent 80 000 intact forest. Starting in final year planting programme established corridor, we trapped two species native small mammals, Bush Rat (Rattus fuscipes) and Cape York leucopus), within nearby linkage. used data ear clippings determine side corridor animals originated from, by comparing this information trap locations, identified 16 long-distance movements through corridor. As allowed be detected single capture event as it reflected movement birth, approach yielded considerably more than records alone. The combination species-specific assessment function, revealing use occupation was higher for neither symmetrical nor uniform. Long-distance were most common immediately after restoration, dropping off reconstructed colonized.
