“…So far, only 42 species of bats are known to occur for Rio Grande do Norte (Barros 2014; Barros et al 2017;Cordero-Schmidt et al 2017;Vargas-Mena et al 2018), which is still considered a low richness when compared to nearby states such as Pernambuco (n = 73), Paraíba (n = 63) and Ceará (n = 62) (Garcia et al 2014). The present study provides the first data on the bat fauna of the coastal restingas of Rio Grande do Norte.…”

Atualmente, quarenta e uma espécies de morcegos são conhecidas para as restingas do Brasil. No entanto, a maioria dos estudos sobre morcegos das restingas são limitados às regiões sul e sudeste do Brasil, deixando a região nordeste com uma lacuna de conhecimento. O presente artigo apresenta dados sobre morcegos capturados em três áreas de restinga do município de Tibau do Sul, Rio Grande do Norte, levantados a partir de uma amostragem de curta duração. Redes de neblina para captura de morcegos foram armadas próximas ao solo e sobre o corpo d’água. Foram capturados 38 indivíduos de seis espécies de duas famílias: cinco Phyllostomidae e um Molossidae. O morcego Carollia perspicillata (Linnaeus, 1758) foi a espécie mais abundante. Apresentamos aqui a primeira lista de morcegos capturados em área de restinga para o Rio Grande do Norte.Palavras chave: Molossidae, Nordeste, Novo registro, Phyllostomidae, Tibau do Sul.Abstract: Currently, forty-one species of bats are known to occur in the restingas of Brazil. However, most studies on restingas’ bats are limited to the south and southeastern regions of Brazil, leaving the northeastern region with a gap of knowledge. The present article presents data on bats captured in three areas of restinga of the municipality of Tibau do Sul, Rio Grande do Norte, collected from a short-term sampling. Mist nets were used to capture bats near the ground and the water bodies. Were captured 38 individuals of six species and two families: five Phyllostomidae and one Molossidae. The bat Carollia perspicillata (Linnaeus, 1758) was the most abundant species. We present here the first list of bats captured in the restinga area for the Rio Grande do Norte State.Key words: Molossidae, New record, Northeast, Phyllostomidae, Tibau do Sul.

“…A lacuna para quirópteros era igualmente grande até levantamentos recentes (e.g. Vargas-Mena et al 2018). Diferente dos estados vizinhos, o Rio Grande do Norte não foi visitado por expedições históricas, que realizadas a partir do século XVII impulsionaram o conhecimento sobre mamíferos no restante do nordeste do Brasil (Feijó & Langguth 2013).…”

RESUMO. Mamíferos de médio e grande porte são especialmente afetados pela caça e perda de habitat, ao mesmo tempo que desempenham importantes funções no ecossistema. O conhecimento sobre esse grupo na Caatinga, a floresta tropical sazonalmente seca do nordeste do Brasil, contudo, ainda é escasso. Neste trabalho realizamos o primeiro levantamento sistemático de mamíferos de médio e grande porte no estado do Rio Grande do Norte, através de armadilhamento fotográfico em 188 pontos distribuídos em 10 áreas prioritárias para a conservação da biodiversidade da Caatinga. Com um esforço amostral de 7271 câmeras-dias, obtivemos 1607 registros de 14 espécies nativas, distribuídas em seis ordens e 10 famílias: oito espécies da ordem Carnivora, duas espécies da ordem Cingulata, e uma espécie para cada uma das demais ordens (Artiodactyla, Didelphimorphia, Pilosa e Primates). A riqueza encontrada representa 31% das 45 espécies de mamíferos de médio e grande porte que ocorrem na Caatinga, e 50% das espécies deste grupo registradas no domínio da Caatinga ao norte do Rio São Francisco, ampliando significativamente o conhecimento sobre o grupo na região. Entre as espécies registradas estão três felinos ameaçados de extinção, incluindo um grande predador de topo (Leopardus tigrinus, Herpailurus yagouaroundi e Puma concolor). O baixo número de registros de algumas espécies e a ausência de outras indicam o estado crítico da mastofauna do estado e sugerem a importância e urgência do estabelecimento de novas unidades de conservação na Caatinga do Rio Grande do Norte.ABSTRACT. Medium to large-sized mammals from the Caatinga of the Rio Grande do Norte, in Northeast Brazil. Medium to large-sized mammals are the most affected by habitat loss and hunting, while at the same time playing important roles in the ecosystem. The knowledge about this group in the Caatinga, the dry tropical forest of northeastern Brazil, however, is still scarce. In this study, we carried out the first systematic survey of medium to large-sized mammals in the Rio Grande do Norte state, with camera traps installed in 188 points distributed in 10 priority areas for the conservation of the Caatinga biodiversity. With a sampling effort of 7271 camera-days, we obtained 1607 records of 14 native medium to large-sized mammals, distributed in six orders and 10 families: eight species of the order Carnivora, two species of the order Cingulata, and one species for each of the other orders (Artiodactyla, Didelphimorphia, Pilosa e Primates). The richness recorded represents a third of the 45 large and medium-sized mammal species found in the Caatinga, and half of the large and medium-sized mammal species recorded in northern Caatinga dominium, significantly increasing the knowledge about the group in the region. Among the recorded species are three threatened felids, including a large top predator (Leopardus tigrinus, Herpailurus yagouaroundi, and Puma concolor). The low number of records of some

“…We used carcasses of house mice ( Mus musculus ; C57BL/6 strain) and chicks (from domestic chickens; 1 day old) acquired in animal houses and shops, and carcasses of bats (flat‐faced fruit‐eating bat) collected in urban areas 30 days before each test. We used flat‐faced fruit‐eating bats because they are very abundant in the study area (Barros 2019) and in the state of Rio Grande do Norte in general (Barros et al 2017, Vargas‐Mena et al 2018). We killed all animals by cervical dislocation, and immediately froze the carcasses and kept them at −18ºC for a maximum of 30 days until we used them in the trials.…”

Factors affecting searcher efficiency and scavenger removal of bat carcasses in Neotropical wind facilities

et al. 2022

Bat fatalities at wind facilities have been reported worldwide, and environmental impact assessments depend on searches for carcasses around wind turbines to quantify impacts. Some of the carcasses may go undetected by search teams or be removed by scavengers during search intervals, so these biases must be evaluated and taken into account in fatality estimation. We investigated the influence of different factors on searcher efficiency and scavenger removal in a dry forest area in northeastern Brazil, one of the regions with the highest density of wind turbines in the Neotropics. We conducted searcher efficiency and scavenger removal trials around 34 wind turbines from January 2017 to January 2018. Searcher efficiency was influenced by cover type, season, and carcass size, ranging between 12% for small bats in shrub vegetation during the rainy season and 96% for large bats in absent or sparse vegetation during the dry season. Carcass type and season affected scavenger removal; carcass persistence time was shorter for chicks (1.2 days) than for bats and mice (2.1 days), and the probability of a carcass persisting for a whole day was higher in the rainy season, while the probability of carcass persistence for 7, 14, and 28 days was higher in the dry season. The scavenger community was composed of canids, birds of prey, and insects, with systematic removal of carcasses by the crab‐eating fox (Cerdocyon thous) throughout the year and by dung beetles in the rainy season. Based on our findings, impact assessments of wind facilities on bats should conduct searcher efficiency trials in all seasons and cover types around wind turbines, using bat carcasses or models of different sizes. Scavenger removal trials should cover all seasons as well, and use mouse carcasses (but not chick carcasses) as surrogates for bats.
