Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...
Caught on camera: How climate, biodiversity, and landscape influence sarcoptic mange occurrence in red foxesNARA Subscribed
Sarcoptic mange, a widespread and highly contagious disease caused by Sarcoptes scabiei mites, affects a wide range of mammals, including the red fox ( Vulpes vulpes ). Being a zoonosis, mange can be considered a potential public health issue, of conservation relevance, as many wildlife species are susceptible to mite infection, with impacts on individuals’ fitness and populations’ viability. This study aimed to estimate the p...
Mind the Gaps: Shortfalls in Studies of the Intraspecific Genetic Diversity of Plants Across the Gran ChacoNARA Subscribed
Intraspecific genetic diversity (IGD) is a fundamental component of biodiversity, essential for understanding the evolutionary histories and demographic processes of species, and is key to effective conservation planning. However, ecologically important regions such as the Gran Chaco, South America's second‐largest forested biome, remain largely underexplored. Encompassing diverse vegetation across climatic and altitudinal gra...
SARS-CoV2 Nsp1 is a metal-dependent DNA and RNA endonucleaseNARA Subscribed
Over recent years, we have been living under a pandemic, caused by the rapid spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2). One of the major virulence factors of Coronaviruses is the Non-structural protein 1 (Nsp1), known to suppress the host cells protein translation machinery, allowing the virus to produce its own proteins, propagate and invade new cells. To unveil the molecular mechanisms of SARS...
Preliminary profile of the gut microbiota from amerindians in the Brazilian amazon experiencing a process of transition to urbanizationNARA Subscribed
The Yanomami are one of the oldest indigenous tribes in the Amazon and are direct descendants of the first people to colonize South America 12,000 years ago. They are located on the border between Venezuela and Brazil, with the Venezuelan side remaining uncontacted. While they maintain a hunter-gatherer society, they are currently experiencing contact with urbanized populations in Brazil. The human gut microbiota of traditiona...
Aim Water availability is the major driver of tropical forest structure and dynamics. Most research has focused on the impacts of climatic water availability, whereas remarkably little is known about the influence of water table depth and excess soil water on forest processes. Nevertheless, given that plants take up water from the soil, the impacts of climatic water supply on plants are likely to be modulated by soil water con...
Continental‐scale acoustic telemetry and network analysis reveal new insights into stock structureNARA Subscribed
Delineation of population structure (i.e. stocks) is crucial to successfully manage exploited species and to address conservation concerns for threatened species. Fish migration and associated movements are key mechanisms through which discrete populations mix and are thus important determinants of population structure. Detailed information on fish migration and movements is becoming more accessible through advances in telemet...
NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the NeotropicsNARA Subscribed
Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal specie...
An association between differential expression and genetic divergence in the Patagonian olive mouse ( Abrothrix olivacea )NARA Subscribed
Recent molecular studies have found striking differences between desert‐adapted species and model mammals regarding water conservation. In particular, aquaporin 4, a classical gene involved in water regulation of model species, is absent or not expressed in the kidneys of desert‐adapted species. To further understand the molecular response to water availability, we studied the Patagonian olive mouse Abrothrix olivacea , a spec...
