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...
Are functional traits of host fish good predictors of parasite species composition in a tropical middle American stream?NARA Subscribed
Host functional traits are widely used to explain patterns of parasite diversity and community structure; however, their predictive power in species‐rich Neotropical freshwater systems remains poorly understood. We examined whether host traits predict helminth parasite community composition in the Lacantún River (southern Mexico), using presence/absence data for 74 helminth genera recorded from 58 fish species. We evaluated a...
Purpose Conventional Life Cycle Assessment (LCA) studies of agricultural systems frequently utilize mass-based functional units, neglecting the consideration of product quality integration. This study aims to address this gap by integrating agronomic productivity, bioactive quality (pungency), and environmental footprint into a unified LCA framework for Rocoto chili cultivation. The study will employ primary high-fidelity expe...
Role of autonomic receptors in ethyl ferulate-induced cardiovascular effects in normotensive and hypertensive female ratsNARA Subscribed
Aims Ethyl ferulate (EF) may offer novel benefits in hypertension. We investigated the contribution of autonomic receptors to EF-induced effects in female Wistar and SHR. Methods Anesthetized females received EF intravenously at 7.5, 15, or 30 mg/kg. Autonomic involvement was evaluated using pretreatment with atropine, atenolol, or hexamethonium. MAP and HR were continuously monitored. Results EF induced rapid and pronounced r...
The dynamics of coastal macroalgal assemblages after the Fundão dam disaster: challenges and lessons from impact assessmentNARA Subscribed
Anthropogenic marine disasters impair biodiversity, ecosystem services provisioning, and socioeconomic development, with long-lasting consequences. Robust impact assessment, however, depends on understanding the spatiotemporal variability of the indicators used to detect change. Here, we present the results of a monitoring program (2018–2025) targeted at two Coastal and Marine Protected Areas located 40 km south of the Doce Ri...
In recent years, both the number and the size of ships have increased considerably, whereas port areas have expanded much more slowly. As a result, port manoeuvres are increasingly performed in restricted waters, which increases navigational risk during ship operations. For this reason, ship-handlers must know the instantaneous position of the pivot point (PP) at any time. The aim of this paper is to propose novel mathematical...
The Canary Islands region exhibits intense mesoscale activity, with eddies generated south the islands by perturbations of the Canary Current. After detachment, these eddies drift southwestward along the Canary Eddy Corridor (CEC), exporting their properties into the open ocean. While mesoscale dynamics in the region are well documented, associated submesoscale structures and their role in the production, transport and reminer...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Tropical Dry Forests Challenge Macroecological Rules of Positive Relationships Between Species' Niche Breadth, Range Size and AbundanceNARA Subscribed
Aim Niche theory has played a central role in explaining species spatial distribution, to the point that the niche breadth ‐ range and range‐abundance relationships are often cited as macroecological rules. We test the generality of these rules by evaluating the interdependencies between species niche breadth, range and abundance in tropical dry forests (TDF), a disjunct ecosystem known to harbour many locally dominant, range‐...
A hybrid framework to estimate live fuel moisture content through land surface modellingNARA Subscribed
Wildfires are among the most powerful natural phenomena that have severe environmental and social impacts. Their increasing frequency and intensity, driven by climate change and unsustainable land-use practices, emphasise the importance of reliable fire risk assessment tools. Live fuel moisture content (LFMC) is a key variable for wildfire risk assessment and management, as it directly influences fire behaviour and propagation...
