Discovering the diversity of tadpoles in the mid-north Brazil: morphological and molecular identification, and characterization of the habitat.

Brazil stands out for presenting the highest amphibian anuran diversity in the world. However, taxonomic studies that address characteristic of larval stage of anurans are incipient, representing only 62% of known species. We assess the species diversity of tadpoles from eastern Maranhão state, mid-northern region of Brazil based on morphological and molecular identification (.

The challenge in detecting risk areas of snakebite when case rates are low: the case of Amazonian coral snakes.

Identifying risk areas for envenomation by animals is relevant for public health, such as strategic distribution of antivenoms. Coral snakes are highly diverse in the Amazon, inhabit natural and human-modified environments, and the outcome of the cases tends to be serious and potentially lethal due to their neurotoxic venom. By integrating species' geographical records and environmental variables, we used species distribution modeling to predict the distribution of coral snake species in the Brazilian Amazonia.

Madagascar's extraordinary biodiversity: Threats and opportunities.

Madagascar's unique biota is heavily affected by human activity and is under intense threat. Here, we review the current state of knowledge on the conservation status of Madagascar's terrestrial and freshwater biodiversity by presenting data and analyses on documented and predicted species-level conservation statuses, the most prevalent and relevant threats, ex situ collections and programs, and the coverage and comprehensiveness of protected areas. The existing terrestrial protected area network in Madagascar covers 10.

Functional traits and phylogeny explain snake distribution in the world's largest dry forest ecoregion, the Gran Chaco.

Macroecological studies describe large-scale diversity patterns through analyses of species distribution patterns and allows us to elucidate how species differing in ecology, physical requirements, and life histories are distributed in a multidimensional space. These patterns of distributions can be explained by vegetation, and climatic factors, and are determined by historical and current factors. The continuous accumulation of information on the distribution patterns of species is essential to understand the history and evolution of the biota.

Use of geospatial analyses to address snakebite hotspots in mid-northern Brazil - A direction to health planning in shortfall biodiversity knowledge areas.

Knowing the distribution of venomous snakes of medical importance is essential to identify areas at risk for snakebites. Thus, we used an integrative approach based on the application of geographic distribution data of venomous snakes, species distribution modeling (SDM), spatial organization of snakebites, and information on human population density for mapping the potential distribution of snakes and identifying areas at risk of snakebites in the state of Maranhão (mid-northern Brazil). From a compiled database of venomous snake records deposited in biological collections and the literature, we predict the potential distribution of venomous snakes in Maranhão, a state whose diversity and geographic distribution of venomous snake species are poorly known.

Biopsychosocial inequality, active lifestyle and chronic health conditions: a cross-sectional National Health Survey 2013 in Brazil.

This study estimated the biopsychosocial factors related to active physical behavior in the Brazilian population with and without chronic non-transmissible disease (NCD). Cross-sectional study of the National Health Survey (NHS) in Brazil, with 60,202 individuals in 2013. Participants were randomly selected by complex sampling.

Species richness and distribution patterns of the snake fauna of Rio Grande do Norte state, northeastern Brazil.

The Neotropics are one of the richest regions in biodiversity globally. Still, much remains unknown about the mechanisms and processes responsible for the accumulation of species in this region. Among the many limitations on our current knowledge on the region's biodiversity, understanding of community composition and species distributions is limited and greatly biased in many Brazilian regions.

Urinary Incontinence in Physically Active Older Women of Northeast Brazil.

Low- and moderate-impact physical activity (PA) is associated with the prevention of urinary incontinence (UI). The objective of the cross-sectional study presented herein is to analyze the factors associated with UI in physically older active women who participate in senior community groups. The variable UI was measured by the International Consultation Incontinence Questionnaire Short Form (ICIQ-SF).

Back in time to unlock the future: tracing the type-specimens of Corallus hortulana (Linnaeus, 1758) (Serpentes: Boidae), with designation of a lectotype for the Amazon tree boa.

Corallus hortulana presents a large array of tones and color pattern variability throughout its distribution (= polychromatism), which trigged the description of several taxa now considered to be primary synonyms. Linnaeus described two of these (Boa enydris and Boa hortulana) on the same page of the 10th Edition of the Systema Naturae. However, both names had been widely used in literature almost in an optional way, until their formal synonymization more than two centuries after the original description.

Notes on court and copula, fertility, nest, eggs and hatchlings of the Caatinga's black snake Boiruna sertaneja Zaher, 1996 (Serpentes: Dipsadidae) from northeastern Brazil.

The Caatinga's black snake Boiruna sertaneja is a Pseudoboini species, endemic of the Caatinga biome. It is rare and fits in five traits that suggest it deserve more attention in reproduction research and conservation policies. Here we provide information on reproductive biology of B.

Morphological variation of the rare psammophilous species Apostolepis gaboi (Serpentes, Dipsadidae, Elapomorphini).

Apostolepis gaboi was described based only on the holotype found in the Queimadas, state of Bahia, northeastern Brazil. Since its original description, no additional specimens were reported in literature and the species was considered to be rare and poorly known. Here, we provide a detailed description for the species based on the examination of the holotype and 34 additional specimens from the type locality and adjacent areas.

Conceptual and empirical advances in Neotropical biodiversity research.

The unparalleled biodiversity found in the American tropics (the Neotropics) has attracted the attention of naturalists for centuries. Despite major advances in recent years in our understanding of the origin and diversification of many Neotropical taxa and biotic regions, many questions remain to be answered. Additional biological and geological data are still needed, as well as methodological advances that are capable of bridging these research fields.

Infomap Bioregions: Interactive Mapping of Biogeographical Regions from Species Distributions.

Biogeographical regions (bioregions) reveal how different sets of species are spatially grouped and therefore are important units for conservation, historical biogeography, ecology, and evolution. Several methods have been developed to identify bioregions based on species distribution data rather than expert opinion. One approach successfully applies network theory to simplify and highlight the underlying structure in species distributions.
