Effects of climate change on the distributional potential of three range-restricted West African bird species

摘要: A detailed understanding of species' responses to global climate change provides an informative baseline for designing conservation strategies optimize protection biodiversity. However, such information is either limited or not available many tropical species, making it difficult incorporate into planning most species. Here, we used correlative ecological niche models assess potential distributional 3 range-restricted West African birds, Timneh Parrot (Pscittacus erithracus timneh), Ballman's Malimbe (Malimbus ballmanni), and White-necked Rockfowl (Picathartes gymnocephalus), change. We primary biodiversity occurrence records each species obtained from the Global Biodiversity Information Facility, eBird, VertNet; environmental data, climatic variables present future, latter characterized by 2 IPCC representative concentration pathways (4.5, 8.5) future emissions scenarios 27 general circulation a 2050 time horizon. found broad present–day distributions with respect all Future tended be stable closely similar their present-day distributions; contrast, marked change–driven range loss across Parrot. Our results suggest that impacts on birds will in some cases minimal, but individual may respond differently conditions. Thus, these bird diversity general, recommend regional-to-national action plans adaptation species; could provide this prioritization.
