Application of Population Viability Theory to Moose in Mainland Nova Scotia

摘要: Populations of moose (Alces alces americana) in mainland Nova Scotia, Canada, have been reduced to approximately 1,000 individuals fragmented into a number isolated populations. Although the data required for comprehensive population viability assessment (PVA) are not currently available, there some general rules concerning minimum viable (MVP) size that may be applied preliminary assessment. Genetic evidence suggests that, general, genetically effective (Ne) 50 is short-term persistence and 500 5,000 long-term survival. Census (N) generally larger than Ne, 10:1 relationship between N Ne has roughly established populations elsewhere. Given this relationship, = viability. Based on current home range (30-55 km) density (0.05/km), critical area by estimated 100,000200,000 km. Strategies conservation forest management should concentrate (1) conducting genetic, population, habitat analyses increase understanding limiting factors; (2) reestablishing connectedness among discrete form metapopulation; (3) protecting/enhancing meet requirements population; (4) increasing carrying capacity available support greater
