NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time, and attempts to address it require a clear understanding of how ecological communities respond to environmental change across time and space. While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes, vast areas of the tropics remain understudied. In the American tropics, Amazonia stands out as the world's most diverse rainforest and the primary source of Neotropical biodiversity, but it remains among the least known forests in America and is often underrepresented in biodiversity databases. To worsen this situation, human-induced modifications may eliminate pieces of the Amazon's biodiversity puzzle before we can use them to understand how ecological communities are responding. To increase generalization and applicability of biodiversity knowledge, it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple organism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region's vulnerability to environmental change. 15%–18% of the most neglected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lost

Aspectos epidemiológicos da tuberculose pulmonar nos municípios de Botucatu, Conchas, São Manuel e Avaré, Estado de São Paulo, Brasil, de 1963 a 1972 Epidemiological aspects of pulmonary tuberculosis in Botucatu, Conchas, São Manuel and Avaré (State of S. Paulo), from 1963 to 1972

O diagnóstico da situação da tuberculose pulmonar nos Municípios de Botucatu, Conchas, São Manuel e Avaré, SP, Brasil, baseou-se na prevalência e risco de infecção em escolares de l&ordf; série, em 1972, e em dados de morbidade e mortalidade específica, de 1963 a 1972. Realizou-se inquérito tuberculínico em 2.913 escolares, com PPD 23 RT-2UT; foram analisados os prontuários de 718 casos inscritos no CSI de Botucatu e os atestados de óbito de residentes, incluindo-se os ocorridos em hospitais especializados. As taxas de prevalência de infecção para os quatro Municípios foram respectivamente 2,4%; 6,8%; 1,9% e 4,5%. Para a idade de 7,5 anos, os riscos de infecção foram: 0,27%; 0,32; 0,20% e 0,34%. O nível de infecção apurado caracterizou o conjunto como área de média prevalência da tuberculose pulmonar. Os índices de prevalência de infecção relacionaram-se diretamente à incidência de casos bacilíferos de cada Município. Em 530 casos com baciloscopia, houve 62,0% de positividade. As formas radiológicas moderada e avançada predominaram principalmente em adultos jovens do sexo masculino. Foram registradas alta taxa de abandono (39,5%}, baixo percentual de cura (17,9%) e 3,4% de óbitos; ao redor de 32,0% estava em tratamento. Não houve diferenças estatisticamente significativas das proporções de abandono, segundo procedência por Município ou formas da doença. Invocaram-se razões técnico-administrativas do sistema vigente para explicar esses achados. A incidência média de casos confirmados, no período, foi de 35,4 em Conchas, 33,1 em Avaré, 23,7 em Botucatu e 18,5 em São Manuel (por 100.000). Com casos confirmados e suspeitos os índices foram: 57,6; 48,8; 43,8 e 35,3. Os índices médio-anuais de mortalidade, foram: 7,6 em Botucatu, 12,14 em Conchas, 5,0 em São Manuel e 18,7 em Avaré (por 100.000). Apenas em Botucatu registrou-se declínio das taxas de mortalidade de 1963 a 1972. A mortalidade específica em adultos jovens ainda era elevada, predominando no sexo masculino, principalmente em Conchas. Sublinhou-se a necessidade de descentralizar as atividades antituberculose para atingir um controle eficiente.<br>The diagnosis of the pulmonary tuberculosis situation in Botucatu, Conchas, São Manuel and Avaré (State of S. Paulo) was based on the study of prevalence and risk of infection, in first grade school - children, during 1972, and on morbidity and specific mortality data gathered during a ten year period, 1963 to 1972. Tuberculin survey with PPD 23 RT-2TU was carried out in 2.913 school children; 718 records from the Botucatu Public Health Center and the death certificates of residents who died in these counties or in specialized hospitals were analysed. The prevalence rates of infection for the 4 counties were respectively 2.4, 6.8, 1.9 and 4.5%. The risks of infection for 7.5 year old school-children were 0.27, 0 32, 0.20 and 0.34%. The infection level characterized these counties as constituting a medium prevalence area of pulmonary tuberculosis. The prevalence rates of infection were directly related to the incidence of smear positive cases, in all these counties. Sixty two percent (62.0) of 530 patients submitted, to direct microscopy were smear positive cases. The predominance of moderately advanced and far advanced pulmonary lesions was observed in male young adults. A high default rate (39.5), a low proportion of cure (11.9%) and death (3.4%) were observed. Thirty two percent were under treatment. There were no statistically significant differences between default cases and county procedence of default cases and extent of pulmonary lesions. These findings were attributed to the present technical and administrative health organization. The average incidence of confirmed cases during this period was 35.4 in Conchas, 33.1 in Avaré., 23.7 in Botucatu and 18.5 in São Manuel (per 100,000). The rates of confirmed and suspected cases together were: 57.6. 48.8, 43.8 and, 35.3. The average annual mortality rates were: 7.6 in Botucatu, 12.1 in Conchas, 5.0 in São Manuel and 18.7 in Avaré (in 100,000). The decreased mortality rates during 1963 to 1972 were observed only in Botucatu. Specific mortality is still high among the young male adults, specifically in Conchas. The need to incorporate the anti-tuberculosis activities in local health services, for effective control of this disease was emphasized
