Item Distance sampling surveys reveal 17 million vertebrates directly killed by the 2020’s wildfres in the Pantanal, Brazil(Scientifc Reports, 2021) Tomas, Walfrido Moraes; Berlinck, Christian Niel; Chiaravalloti, Rafael Morais; Faggioni, Gabriel Paganini; Strüssmann, Christine; Libonati, Renata; Abrahão, Carlos Roberto; Alvarenga, Gabriela do Valle; Bacellar, Ana Elisa de Faria; Batista, Flávia Regina de Queiroz; Bornato, Thainan Silva; Camilo, André Restel; Castedo, Judite; Fernando, Adriana Maria Espinóza; Freitas, Gabriel Oliveira de; Garcia, Carolina Martins; Gonçalves, Henrique Santos; Guilherme, Mariella Butti de Freitas; Layme, Viviane Maria Guedes; Lustosa, Ana Paula Gomes; Oliveira, Ailton Carneiro De; Oliveira, Maxwell da Rosa; Pereira, Alexandre de Matos Martins; Rodrigues, Julia Abrantes; Semedo, Thiago Borges Fernandes; Souza, Rafael Augusto Ducel de; Tortato, Fernando Rodrigo; Viana, Diego Francis Passos; Vicente‑Silva, Luciana; Morato, RonaldoAnthropogenic factors have signifcantly infuenced the frequency, duration, and intensity of meteorological drought in many regions of the globe, and the increased frequency of wildfres is among the most visible consequences of human-induced climate change. Despite the fre role in determining biodiversity outcomes in diferent ecosystems, wildfres can cause negative impacts on wildlife. We conducted ground surveys along line transects to estimate the frst-order impact of the 2020 wildfres on vertebrates in the Pantanal wetland, Brazil. We adopted the distance sampling technique to estimate the densities and the number of dead vertebrates in the 39,030 square kilometers afected by fre. Our estimates indicate that at least 16.952 million vertebrates were killed immediately by the fres in the Pantanal, demonstrating the impact of such an event in wet savanna ecosystems. The Pantanal case also reminds us that the cumulative impact of widespread burning would be catastrophic, as fre recurrence may lead to the impoverishment of ecosystems and the disruption of their functioning. To overcome this unsustainable scenario, it is necessary to establish proper biomass fuel management to avoid cumulative impacts caused by fre over biodiversity and ecosystem services.Item The rarest of the rare: rediscovery and status of the critically endangered Belem Curassow, Crax fasciolata pinima (Pelzeln, 1870)(Papéis Avulsos de Zoologia, 2018) Alteff, Eduardo França; Gonsioroski, Gustavo; Barreiros, Marcelo; Torres, Leonardo Gabriel C. de Oliveira; Camilo, André Restel; Mozerle, Hugo Borghezan; Sousa, Antônio Emanuel B. A. de; Medolago, César Augusto Bronzatto; Martínez, Carlos; Lima, Diego Mendes; Ubaid, Flávio Kulaif; Mendonça, Eloisa Neves; Tomotani, Barbara Mizumo; Silveira, Luís FábioThe Belem Curassow (Crax fasciolata pinima) is one of the most endangered birds in South America, without sight ings 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 individu als 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), es timating 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.
