Organomineral fertilization with sewage sludge: heavy metal content in the soil and bioaccumulation in Urochloa brizanthaNARA Subscribed
The use of sewage sludge as biochar or compost in organomineral fertilizers has been investigated as an alternative to mineral fertilizers, as it can maintain crop yields, reduce environmental impacts, and improve soil quality. Therefore, this study aimed to evaluate the efficiency of organomineral fertilizers derived from sewage sludge and lignolytic compounds, formulated through different technologies, on the bioaccumulation...
The nonpeptide angiotensin-(1–7) mimic AVE0991 attenuates neuroendocrine and behavioral responses to chronic unpredictable stressNARA Subscribed
Rationale Chronic stress, frequently associated with dysfunction of the hypothalamic–pituitary–adrenal (HPA) axis and reduced neuroplasticity, is a major risk factor for psychiatric disorders such as anxiety and depression. Objective The present study aimed to validate a 21-day chronic unpredictable stress (CUS) model and to investigate the effects of the Mas receptor agonist AVE0991 on stress-induced behavioral and molecular...
Lichen-derived atranorin effects on cultivable gut-associated bacteria in Constrictotermes cyphergasterNARA Subscribed
Chemical defenses produced by lichens represent a yet underexplored force shaping trophic interactions beyond direct consumer deterrence. In termites, dietary intake of such compounds may extend their effects to gut-associated microbial consortia, with consequences for host physiology and colony performance. However, the extent to which lichen-derived metabolites influence microorganisms in insect hosts remains poorly understo...
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...
The growing demand for offshore oil and gas production in deep waters has motivated the development of technologies to enable the continuous, reliable, and cost-effective monitoring of subsea equipment. Traditional inspection techniques rely on ROVs and AUVs, leading to delays between data acquisition and recovery and high operational costs. Underwater acoustic communication systems represent an attractive alternative for tran...
The biomedical engineer’s pledge: overview and contextNARA Subscribed
Although biomedical engineering (BME) is a profession with ethical responsibilities comparable to those in medicine, it has, until now, lacked a counterpart to the Hippocratic Oath. While professional societies have established codes of ethics for biomedical engineers, these documents lack the symbolic and ceremonial significance of an oath or pledge. By contrast, the recitation of the Hippocratic Oath, or its modern version,...
The effects of global climate change on biodiversity and ecosystem functioning are unevenly distributed in the geographic space. Identifying sites more suitable to sustain biodiversity in a changing climate is essential to both species conservation and restoration strategies at different scales. Here, we map terrestrial climate‐resilient sites for biodiversity across Brazil to identify sites with greater chances of providing s...
The repeated evolution of herbicide resistance in agriculture provides an unprecedented opportunity to understand how organisms rapidly respond to strong anthropogenic‐driven selection pressure. We recently identified agricultural populations of the grass species Bromus tectorum L. with resistance to multiple herbicides. To understand the evolutionary origins and spread of resistance, we investigated the resistance mechanisms...
Controlling Levallois: the effect of hammer angle of blow on Levallois flake morphology and fracture trajectoryNARA Subscribed
Discussions of the Levallois method typically focus on the preparation of the core surface geometry as the primary factor in determining the characteristics of Levallois products. While some studies have acknowledged the role of knapping gestures, there is still limited empirical investigation into how different force application parameters influence the formation of these flakes. This study presents the results from a set of...
Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
Pre-Roman glass craftsmanship reached its summit with the development of complex polychrome glass beads, being the Phoenician glass pendants the most exquisite and elaborate example. The uniqueness and complexity of such findings could reveal key information for the understanding of the production and trade of glass pieces at that age. However, these findings have practically never been studied from a physic-chemical perspecti...
