Evaluating the phytotoxicity of sodium diclofenac treated with heterogeneous photocatalysisNARA Subscribed
Pharmaceuticals are increasingly detected in surface water, and even at trace concentrations, they may pose ecological and health risks. In this study, heterogeneous photocatalysis using titanium dioxide (TiO 2 ) was applied under simulated solar irradiation to degrade sodium diclofenac. Irradiation times of 60, 120, and 180 min were used with a TiO 2 loading of 0.6 g L −1 . Under these conditions, only ~ 20% diclofenac degrad...
Navío Quebrado Lagoon is a shallow coastal waterbody connected to the Caribbean Sea through an inlet, and it lies within Colombia’s protected-area system, specifically, the Los Flamencos Flora and Fauna Sanctuary. In this work we set up the Environmental Fluid Dynamics Code Plus (EFDC+) model to examine salinity behavior across 2024, combining field measurements with hydrological, meteorological, and tidal datasets obtained fr...
Mussels enhance digestive enzyme activity in preparation for stressful fluctuating environmentsNARA Subscribed
Elevated heat and low phytoplankton abundance are physiologically and ecologically challenging marine organisms of the northeast Pacific, including the mussel Mytilus californianus . During low tide, mussels are exposed to warm air and undergo anaerobic metabolism. Tidal variation coincides with daily fluctuations in food availability requiring flexible response systems (e.g., changes in digestive enzyme activity) to maintain...
Aotearoa New Zealand’s marine carbon cycle in a changing climate – Current understanding and future directionsNARA Subscribed
The marine system plays a critical role in the global climate cycle, as a major control of atmospheric carbon dioxide (CO 2 ). Marine primary production (photosynthesis) and remineralisation of organic carbon (respiration, degradation) determine the amount of CO 2 sequestered in marine sediments and deep‐water environments on century to millennial timescales. The stocks and fluxes of the marine carbon cycle are susceptible to...
Phylogenetic and Functional Biogeographic Approach for Rodent Conservation Across an Environmental Gradient in ChileNARA Subscribed
Aim Understanding how abiotic factors influence species diversity, evolution and functional patterns of species is crucial for biodiversity conservation and for the management of terrestrial protected areas. We evaluate biogeographic and phylogenetic metrics in rodents to understand biodiversity patterns and improve wildlife conservation strategies. Location Chile, South America. Taxon Rodents (Mammalia, Rodentia). Methods We...
In an era where global climate change is shifting plant phenology, global meta-analyses of multiple species are required more than ever. Common language or references for enhanced data compatibility are key for such analyses. Although the Plant Phenology Ontology (PPO) addresses this challenge, it does not capture several relevant reproductive structures that are critical in species with long reproductive cycles, like many Euc...
Sex‐change in hermaphroditic fishes is a complex but natural biological phenomenon that has significant implications for aquaculture fingerling production, selective breeding, and grow‐out. Understanding the physiological, endocrinological, and molecular pathways underlying hermaphroditism in fishes offers unique opportunities to manipulate male‐to‐female and female‐to‐male transitions and maintain desired sex‐ratios in hatche...
Tropical Land‐Use Change Disrupts Zeta‐Diversity Across TaxaNARA Subscribed
Land‐use change causes community turnover via local extinction and colonisation of species, driving biotic homogenization or heterogenization at larger spatial scales. Quantification of these processes has focused on beta‐diversity metrics, which upweight rarity and overlook the role of widespread species. A key knowledge gap is understanding the impact of land‐use change on both rare and widespread species—zeta‐diversity—allo...
The Chapopote Knoll at 3200 m depth, in the southern Gulf of Mexico harbors highly diverse benthic habitats, including massive asphalt flows and surficial gas hydrates with gas seepage. Its associated benthic megafauna includes endemic cold-seep species and background species. This study describes the benthic habitat preferences, distribution patterns and diets of three crustacean species, the caridean shrimp Alvinocaris muric...
Mercury in aquatic ecosystems of two indigenous communities in the Piedmont Ecuadorian Amazon: evidence from fish, water, and sedimentsNARA Subscribed
Mercury is a highly toxic element present in water, soil, air, and biota. Anthropogenic activities, such as burning fossil fuels, mining, and deforestation, contribute to the presence and mobilization of mercury between environmental compartments. Although current research on mercury pathways has advanced our understanding of the risks associated with human exposure, limited information exists for remote areas with high divers...
