A depth-dependent constitutive framework for stratified non-newtonian flows: beyond homogeneous Herschel–Bulkley rheologyNARA Subscribed
Geophysical mass flows such as mudflows and lahars commonly exhibit vertical heterogeneity, often inferred from observed concentration gradients associated with particle settling, consolidation, and fines migration. Standard Herschel–Bulkley (HB) rheology assumes spatially uniform material parameters and therefore cannot explicitly represent depth-dependent rheological structure. This work introduces a depth-dependent constitu...
Localized cutaneous leishmaniasis (LCL) is the most prevalent form of leishmaniasis, with infection control primarily dependent on cell-mediated immunity. Lesion healing results from a complex interplay among immune cells and soluble mediators. Using Luminex technology, we evaluated circulating and lesion microenvironment immune mediators, including chemokines, cytokines, and growth factors, in patients with LCL and nonspecifi...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forestNARA Subscribed
The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from dif...
Distance decay 2.0 – A global synthesis of taxonomic and functional turnover in ecological communitiesNARA Subscribed
Aim Understanding the variation in community composition and species abundances (i.e., β‐diversity) is at the heart of community ecology. A common approach to examine β‐diversity is to evaluate directional variation in community composition by measuring the decay in the similarity among pairs of communities along spatial or environmental distance. We provide the first global synthesis of taxonomic and functional distance decay...
Summary Colwellia psychrerythraea is a marine psychrophilic bacterium known for its remarkable ability to maintain activity during long‐term exposure to extreme subzero temperatures and correspondingly high salinities in sea ice. These microorganisms must have adaptations to both high salinity and low temperature to survive, be metabolically active, or grow in the ice. Here, we report on an experimental design that allowed us...
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyon...
