“…Some studies have found these tendencies to geographic reduction in tropical mountain species of South America, such as the threatened birds of the northern Andes in Colombia (Velásquez-Tibatá et al, 2012) and birds of the Atlantic forest in Brazil (Vieira de Souza et al, 2011). Moreover, the geographic range reduction (63%) is not far from the projections for range-restricted birds of the northern Andes in Colombia for 2050 (33-43%) (Velásquez-Tibatá et al, 2012).…”

a b s t r a c tIn this study we projected the effect of anthropogenic climate change in endemic and restricted-range Andean bird species that spread out from the center of Bolivia to southeastern Peru. We also analyzed the representation of these species in protected areas. The ensemble forecasts from niche-based models indicated that 91-100% of species may reduce their range size under full and no dispersal scenarios, including five species that are currently threatened. The large range reduction (average 63%) suggests these mountain species may be threatened by climate change. The strong effects due to range species losses are predicted in the humid mountain forests of Bolivia. The representation of bird species also decreased in protected areas. Partial gap species (94-86%) are expected to increase over the present (62%). This suggests climate change and other non-climate stressors should be incorporated in conservations plans for the long-term persistence of these species. This study anticipates the magnitude of shifts in the distribution of endemic birds, and represents in the study area the first exploration of the representation of rangerestricted Andean birds in protected areas under climate change.

Ecological niche modeling (ENM) can be used to find areas of high environmental suitability, which are used as a surrogate of abundance's estimation. However, the relationship between environmental suitability and local abundance has been rarely tested. In this study we tested this relationship for the nectar-feeding bat Anoura caudifer. We ran an ENM using Maxent with 235 presence records and seven environmental variables to obtain suitability values, gathering relative abundance data for 24 sites from published studies. We found a very strong relationship between abundance and suitability for A. caudifer, with suitability predicting 64% of the spatial variation of abundance. When ENM is correlated with spatial variation of abundance, it can be used as a proxy to forecast the impact of changing climate on abundance. We suggest that the positive relationship found for this common species may be applied to rare nectarivore bat species, helping to guide new surveys and to find unknown populations.

Potential distribution patterns of scorpions in north‐eastern Brazil under scenarios of future climate change

et al. 2019

Current predictions about the responses of species to climate change strongly rely on projecting altered environmental conditions on their distributions. In this study, we investigated the effects of future climate change scenarios on the potential distribution of 10 species of scorpions in north‐eastern Brazil in the context of their degree of specialisation to closed (Atlantic and Amazon Forests) and open (Caatinga and Cerrado) habitats. Scorpion species were classified as habitat specialists or generalists according to the IndVal index, and present and future species distribution models were prepared using minimum volume ellipsoids. According to IndVal, four species were classified as closed‐forest specialists (Ananteris mauryi, Tityus brazilae, Tityus pusillus and Tityus neglectus), four as open‐forest specialists (Jaguajir agamemnon, Jaguajir rochae, Physoctonus debilis and Bothriurus rochai), and two as generalists (Tityus stigmurus and Bothriurus asper). All species presented a drastic reduction in potential distribution, ranging from 44% to 72%, when compared with their current distribution. In addition, we found a reduction in scorpion species richness under future climate change scenarios. This finding has implications for scorpion conservation. Further, the results show that climate change may impact the composition of scorpion assemblages in north‐eastern Brazil, revealing important implications for human–scorpion interactions.
