An updated synthesis on appropriate science-based criteria for "favourable reference population" of the Scandinavian wolf (Canis lupus) population

摘要: This report provides an updated synthesis on appropriate science-based criteria for "favourable reference population" FRP the Scandinavian wolf (Canis lupus) population and present quantitative values FRP. The assignment was given by Swedish Environmental Protection Agency to SKANDULV research group at Grimso, SLU, Sweden. A thorough review of ecology genetics is provided, including measurements inbreeding depression in population. Results from earlier MVP analyses are presented, as former suggestions or other management goals consensus not possible achieve among all involved scientist, results therefore presented two different parts. OL, CW, OF, PW HS suggest that value should be 340 Scandinavia, 300 They argue this sub-population connected a larger meta-population with minimum size Ne=500, corresponding approximately 1700 wolves, connection one immigrant large per generation. acknowledge includes also wolves living outside EU territory, long there stipulated connectivity. GC evaluated FCS based strict interpretation Habitats Directive informed previous rulings European Court Justice documents Commission. He finds if Sweden cannot include its national territory fulfill obligations under Directive, will achieved (Ne=500) country carrying capacity. If contrary can separate another half capacity (preliminarily estimated 1200/2=600 wolves) more according connectivity naturally achieved. Non Member States contribute meta-population. There between researchers target coefficient 0.2 lower.
