“…Contractions in birds' suitable area are predicted for species associated with all habitat types, except for riverine, but higher losses are expected to forest species, corroborating our hypothesis. Forest-dependent birds require specific conditions such as several large frugivores that need of tree holes and fleshy-fruited trees for reproduction and feeding (Malanotte et al, 2019;Yatsiuk and Wesołowski, 2020), while the generalist habits of non-forest species allows species to obtain a wider range of resources in different types of habitats, including in disturbed environments (Vázquez-Reyes et al, 2022). For instance, large suitable area losses are predicted for forest dependent birds from Amazonia compared to species associated with open lands in future climate scenarios (Miranda et al, 2019).…”

Biodiversity is already experiencing the effects of climate change through range expansion, retraction, or relocation, potentializing negative effects of other threats. Future projections already indicate richness reduction and composition modifications of bird communities due to global warming, which may disrupt the provision of key ecological services to ecosystem maintenance. Here, we systematically review the effect of morphological, ecological, and geographical traits on the amount of future suitable area for birds worldwide. Specifically, we tested whether body mass, diet, habitat type, movement pattern, range size, and biogeographic realm affect birds' suitable area. Our search returned 75 studies that modeled the effects of climate change on 1,991 bird species. Our analyses included 1,661 species belonging to 128 families, representing 83% of the total, for which we were able to acquire all the six traits. The proportion of birds' suitable area was affected by range size, body mass, habitat type, and biogeographic realm, while diet and movement pattern showed lower relative importance and were not included in our final model. Contrary to expectations, the proportion of birds' suitable area was negatively related to range size, which may be explained by higher climatic stability predicted in certain areas that harbor species with restricted distribution. In contrast, we observed that birds presenting higher body mass will show an increase of the proportion of suitable area in the future. This is expected due to the high exposure of smaller birds to environmental changes and their difficulty to keep thermoregulation. Our results also indicated a low proportion of suitable area to forest-dependent birds, which is in accordance with their higher vulnerability due to specific requirements for reproduction and feeding. Finally, the proportion of suitable area was low for birds from Oceania, which is expected since the region encompasses small islands isolated from continents, preventing their species from reaching new suitable areas. Our study highlights that different traits should be considered when assessing extinction risk of species based on future projections, helping to improve bird conservation, especially the most vulnerable to climate change.

“…This is more severe for forest-specialist birds in Afro-tropic biogeographic realm since they require speci c ecological conditions [13]. For instance, several frugivores require tree holes and eshy-fruited trees for reproduction and feeding, respectively [14,15]. Turacos are among the Afro-tropical montane forest specialist birds and play critical ecological roles mainly as seed dispersers [14].…”

Background Understanding the distribution pattern of species and their suitable habitat is key to focus conservation effort. In the face of climate change, the extent of suitable habitats of species may affect over time thus, their survival and distribution. We aim to determine the distribution and extent of suitable habitats for Tauraco ruspolii and T. leucotis in Ethiopia and predict their range in 2050s and 2070s using MaxEnt algorithm. We used 25 and 29 rarified occurrence points for T. ruspolii and T. leucotis, respectively, and 13 environmental variables. Three regularization multipliers and two cut-off thresholds were used to map the potential suitable habitats for each species under current and future climates. Maps were assembled from these techniques to produce a final composite tertiary maps and investigated the habitat suitability overlap between the two species using the UNION tool in the geographical information system. Result All model run performances were highly accurate for both species. Precipitation of the driest month and vegetation cover are the most influential variables for the habitat suitability of T. ruspolii. The habitat suitability of T. leucotis is also mainly influenced by mean temperature of driest quarter and vegetation cover. Under the current climate, the suitable habitat predicted to T. ruspolii covered about 24639.19 km2, but its range size change shows gain and increase by 156.00% and 142.68% in 2050 and 2070, respectively. The T. leucotis‘s current suitable habitat ranges about 204397.62 km², but this is reduced by 40.84% and 68.67% in 2050 and 2070, respectively. Our modeling also showed that there was suitable habitat overlap between them at the margin of their respective habitat types in time series. Conclusion we concluded that there is a direct or indirect impact of climate change on the suitable habitat range expansion for T. ruspolii and contraction for T. leucotis as well as overlapping of these turaco species in different regions of Ethiopia. Therefore, understanding the distribution of current and future suitable habitats of the two turaco species can provide valuable information to implement conservation practices for the species and the regions as well.

Background Understanding the distribution pattern of species and their suitable habitat is key to focus conservation efforts. Climate change has had notable impact on the distribution and extent of suitable habitats, and the long-term survival of various species.
