Background:Understanding geographic distributions of species is a crucial step in spatial planning for biodiversity conservation, particularly as regards changes in response to global climate change. This information is especially important for species of global conservation concern that are susceptible to the effects of habitat loss and climate change. In this study, we used ecological niche modeling to assess the current and future geographic distributional potential of White‑breasted Guineafowl (Agelastes meleagrides) (Vulnerable) across West Africa.Methods:We used primary occurrence data obtained from the Global Biodiversity Information Facility and national parks in Liberia and Sierra Leone, and two independent environmental datasets (Moderate Resolution Imaging Spectroradiometer normalized difference vegetation index at 250 m spatial resolution, and Worldclim climate data at 2.5′ spatial resolution for two representative concentration pathway emissions scenarios and 27 general circulation models for 2050) to build ecological niche models in Maxent.Results:From the projections, White‑breasted Guineafowl showed a broader potential distribution across the region compared to the current IUCN range estimate for the species. Suitable areas were concentrated in the Gola rainforests in northwestern Liberia and southeastern Sierra Leone, the Tai‑Sapo corridor in southeastern Liberia and southwest‑ern Côte d’Ivoire, and the Nimba Mountains in northern Liberia, southeastern Guinea, and northwestern Côte d’Ivoire. Future climate‑driven projections anticipated minimal range shifts in response to climate change.Conclusions:By combining remotely sensed data and climatic data, our results suggest that forest cover, rather than climate is the major driver of the species’ current distribution. Thus, conservation efforts should prioritize forest protec‑tion and mitigation of other anthropogenic threats (e.g. hunting pressure) affecting the species.
Description
The data analyzed during the current study are available in the following databases: the Global Biodiversity Information Facility (GBIF; https ://www.gbif.org). Data from surveys in Sapo National Park in Liberia and Gola Rainforest National Park in Sierra Leone are available from the corresponding author on reasonable request. Environmental datasets are available at https ://terra .nasa.gov/data and http://www.worldclim.org.
