“…Also, inside this area, there is a high diversity of plants and animals, which includes more than 46 endemic and endangered species [102]. The taxa assessed in the present work are found within this complex, including the critically endangered C. pinima and P. obscura [103,104] Additionally, Chiropotes satanas and Cebus kaapori-the latter being among the 25 species that are at the highest risk of extinction of the World-can also be found in this region [105,106]. Despite its importance for conservation, the "Gurupi Mosaic" has undergone a dramatic reduction in forest cover due to the significant increase in illegal logging [103].…”

Climate change and bird extinctions in the Amazon

In recent years, carbon dioxide emissions have been potentiated by several anthropogenic processes that culminate in climate change, which in turn directly threatens biodiversity and the resilience of natural ecosystems. Tropical rainforests are among the most impacted biological realms. The Belé m endemism center, which is one of the several endemism centers in Amazon, is located in the most affected area within the so-called "Deforestation Arc." Moreover, this region harbors a high concentration of Amazonian endangered bird species, of which 56% of them are considered to be under the threat of extinction. In this work, we sought to evaluate the current and future impacts of both climate change and deforestation on the distribution of endemic birds in the Belé m Area of Endemism (BEA). Thus, we generated species distribution models for the 16 endemic bird species considering the current and two future gas emission scenarios (optimistic and pessimistic). We also evaluated climate change impacts on these birds in three different dispersal contexts. Our results indicate that BAE, the endemic taxa will lose an average of 73% of suitable areas by 2050. At least six of these birds species will have less than 10% or no future suitable habitat in all emission scenarios. One of the main mechanisms used to mitigate the impacts of climate change on these species in the near future is to assess the current system of protected areas. It is necessary to ensure that these areas will continue being effective in conserving these species even under climate change. The "Gurupi Mosaic" and the "Rio-Capim" watershed are areas of great importance because they are considered climate refuges according to our study. Thus, conservation efforts should be directed to the maintenance and preservation of these two large remnants of vegetation in addition to creating ecological corridors between them.

“…Among the taxa assessed as critically endangered and with substantial loss of suitable area, we have Crax fasciolata pinima , a forest taxa that inhabits the most critical part of the Amazon: the Belém endemism center, which comprises the states of Maranhão and Pará (Alteff et al., 2019). In this area, were detected the highest levels of habitat loss in the entire Amazon basin.…”

“…Furthermore, this taxa went 40 years with no records, being rediscovered only recently, in four localities (Alteff et al, 2019). One of these localities is the Gurupi Biological Reserve, which, despite being a PA, has been suffering from illegal logging, with 180.9 ha deforested only in 2021 (Alteff et al, 2019;MapBiomas, 2022). The importance of this area has been highlighted previously by de Moraes et al (2020), and here we reinforce that, of the 39 studied taxa, 19 are found in this PA, including Psophia obscura, a species also assessed as Critically Endangered.…”

The anthropogenic impacts on the environment, including deforestation and the escalating emissions of greenhouse gases, have significantly contributed to global climate change that can lead to alterations in ecosystems. In this context, protected areas (PAs) are pillars for biodiversity conservation by being able, for example, to maintain the viability of populations of endangered species. On the other hand, the species range shifts do not follow the limits of PAs, jeopardizing the conservation of these species. Furthermore, the effectiveness of PAs is consistently undermined by impacts stemming from land use, hunting activities, and illegal exploitation, both within the designated areas and in their adjacent zones. The objectives of this study are to quantify the impacts of climate change on the distribution of threatened and endemic birds of the Amazon biome, evaluate the effectiveness of PAs in protecting the richness of threatened birds, and analyze the representativeness of species within PAs. We found with our results that climate suitability loss is above 80 for 65% of taxa in the optimistic scenario and above 93% in the pessimistic scenario. The results show that PAs are not effective in protecting the richness of Amazonian birds, just as they are ineffective in protecting most of the taxa studied when analyzed individually Although some taxa are presented as “Protected,” in future scenarios these taxa may suffer major shrinkages in their distributions and consequently present population unviability. The loss of climatically suitable areas and the effectiveness of PAs can directly influence the loss of ecosystem services, fundamental to maintaining the balance of biodiversity. Therefore, our study paves the way for conservation actions aimed at these taxa so that they can mitigate current and future extinctions due to climate change.

“…A UC tem uma área de 271 mil ha e conforma com as terras indígenas vizinhas um mosaico de áreas protegidas com mais de 2 milhões de hectares, constituindo o principal remanescente de floresta Amazônica no Maranhão (Celentano et al, 2017; Figura 1) e na Área de Endemismo Belém, a mais ameaçada pelo desmatamento dentre as áreas de endemismos da Amazônia (Almeida & Vieira, 2010;Braz et al, 2017). A REBIO do Gurupi tem grande número de espécies de destacado valor para a conservação, das quais 46 espécies de mamíferos e aves endêmicas e/ou ameaçadas de extinção (Carvalho Jr., 2012;Lima et al, 2015;Buss et al, 2017;Carvalho Jr., 2017;Alteff et al, 2019), com destaque para as espécies endêmicas Cebus kaapori, Chiropotes satanas, Psophia obscura e Crax fasciolata pinima, com status de criticamente ameaçadas de extinção, de acordo com a lista oficial brasileira (MMA, 2014).…”

O protocolo de armadilhamento fotográfico TEAM para o monitoramento de vertebrados terrestres de médio e grande porte permite estimativas de parâmetros da biodiversidade que informam os gestores de áreas protegidas sobre os impactos de ameaças ou de ações de manejo da biodiversidade. Neste trabalho, apresentamos resultados de 4 anos do monitoramento TEAM na Reserva Biológica do Gurupi com objetivo de avaliar sua efetividade na conservação de vertebrados terrestres de médio e grande porte da Amazônia maranhense. Foram avaliadas tendências temporais na riqueza e composição da comunidade, nas taxas de ocupação das espécies monitoradas e no Wildlife Picture Index, índice sensível às mudanças na biodiversidade. Foram registradas 36 espécies de vertebrados de médio e grande porte, representando 72% das aves e 96% dos mamíferos com ocorrência na Amazônia maranhense. As populações monitoradas, inclusive de espécies endêmicas e ameaçadas de extinção, permaneceram estáveis ao longo de 4 anos de monitoramento. A taxa de ocupação da maioria das espécies aumentou no período de monitoramento, refletindo no aumento do Wildlife Picture Index. Possivelmente essas tendências têm relação com o grande incêndio florestal que assolou a Reserva Biológica do Gurupi em 2015, indicando a recuperação da biota e a resiliência frente a eventos extremos. Os resultados obtidos demonstram que a Reserva Biológica do Gurupi tem sido efetiva e tem papel de destaque na conservação de vertebrados terrestres de médio e grande porte da Amazônia maranhense.
