“…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.

“…Despite recent research projects and field expeditions, as the "Programa de Pesquisa em Biodiversidade (PPBio)" (Carneiro et al 2012;Dornas et al 2014;Lima et al 2014) engaged by teams from the Universidade Federal do Maranhão and Museu Paraense Emílio Goeldi, which greatly increased the geographic representation of species within the Amazon region, both set of records (revised and post Oren (1991)) are still largely concentrated in the central region of the state and along the coast (Fig. 2a, b).…”

“…Almost three decades have passed since Oren published his "Checklist of the birds of Maranhão, Brazil." During this time, several studies focused on the regional avifauna, covering its different environments, gathering information, and so, adding new records to Oren's (1991) former list (e.g., Olmos and Brito 2007;Soares and Rodrigues 2010;Carvalho et al 2010;Rodrigues et al 2010;Santos et al 2010;Oren and Roma 2011;Lima and Raices 2012;Gonsioroski 2014;Lima et al 2014). In addition, studies aiming to evaluate the environmental impact of great enterprises were performed in the state, and management plans for wildlife conservation were elaborated in the last three decades.…”

An updated documented inventory and new records of bird species for the Brazilian state of Maranhão

et al. 2020

Herein, we present a checklist of birds from the state of Maranhão, northern Brazil. This region is one of the most heterogeneous areas in the country, comprising upland and flooded rainforests, open vegetation cover types, typical from Cerrado and Caatinga, and mangroves along a wide coastal line (an important route for many migratory birds). Climate is either equatorial with dry winter in the savanna-dominated portion or equatorial monsoonal in the forested part. We compiled from the literature, institutional collections, and virtual databases 14,598 occurrence records, corresponding to 728 species from 88 families and 30 orders. Thus, we add 92 new species to those reported almost three decades ago for the same region. A total of 46 species are endemic to Brazil, 30 represent Amazon forest endemics, 21 are endemic to the Belem Area of Endemism, 11 are endemic to Cerrado, and 9 are Caatinga endemisms. From native and resident species, 33 taxa are considered threatened by national laws. This work fills a gap of knowledge on avifauna diversity and confirms the biological relevance of this ecotone region within northern Brazil. Finally, considering the intensive environmental degradation occurring in the study area and the high number of endemic and threatened species observed therein, we reinforce the need of public policy and civil awareness to engage conservation actions and other activities supporting the maintenance of this biodiversity.

“…In Maranhão, we concentrated the field campaigns in the north portion of the Reserva Biológica do Gurupi (Rebio do Gurupi), located in the municipality of Centro Novo do Maranhão (03°15'57"S, 46°42'00"W). The 271.000 ha nature reserve also includes the municipalities of Bom Jardim and São João do Carú (Lima et al, 2014). Field campaigns also took place in other two indigenous territories: the Terra Indígena Alto Turiaçu (TIAT) in Centro Novo do Maranhão (02°54'38"S, 46°24'52"W), and the Terra Indígena Caru (TIC) in Bom Jardim (03°41'59"S, 46°03'16"W).…”

The Belem Curassow (Crax fasciolata pinima) is one of the most endangered birds in South America, without sightings of birds in the wild for 40 years. This subspecies is nationally and internationally classified as critically endangered and close to extinction, suffering from poaching and deforestation in its range. Here we present new records of free-living individuals made on three indigenous lands in Pará and Maranhão states: in part of Terra Indígena Mãe Maria, Bom Jesus do Tocantins, Pará; in locations within the Reserva Biológica do Gurupi/Terra Indígena Alto Turiaçu, Centro Novo do Maranhão, Maranhão; and around the Terra Indígena Rio Pindaré, Alto Alegre do Pindaré, Maranhão. We also provide recommendations to protect this bird via a dedicated conservation program which includes finding new individuals in non-sampled areas (north of BR-222), estimating population size, enhancing taxonomic and natural history knowledge, capturing wild animals in order to start urgent ex situ conservation programs, and developing environmental awareness programs with the local and indigenous populations.
