Predictors of extinction risk of passerine birds in a Central European country

摘要: To develop effective conservation measures, it is crucial that we understand how ecological and life-history traits relate to risk of species extinction. Through the use phylogenetic generalized least-squares regression, this study assesses relative importance habitat specialization, life history, migration strategy climatic niche as predictors national threat level for 86 passerine bird breeding in Czech Republic. We found that, after controlling variation distribution, slow history increases extinction specialist species, but reduces such generalists. The higher specialists consistent with their sensitivity human-induced environmental perturbations, most notably loss. However, our results suggest negative effects specialization appear be somewhat compensated by fast history. For example, histories typically display fecundity than histories. At same time, can beneficial generalists are not badly affected destruction specialists. Such able allocate more energy future reproduction could wait optimal conditions before breeding, leading favourable population status long term. Finally, also warmer areas experience colder areas. Although effect usually attributed impact climate change, likely an explanation because lowland regions heavily exploited intensive agriculture industrial urban development. Based upon these results, current effort, especially zones, may sufficiently address requirements
