Impact of open-air dumping of urban solid waste on soil toxicity and properties in a tropical environmentNARA Subscribed
Open dumping (OD) is uncontrolled dumping of solid waste (SW) in an environment. It involves the illegal practice of dumping waste in areas not designated for waste management, such as open lands, flowing water bodies, or exposed waste piles. OD can contain a complex mixture of organic fractions, and various contaminants that, when infiltrated into the soil through leachate, compromise its stability and resistance. These conta...
Human‐induced high densities of large wild herbivores may pose a threat to natural ecosystems, modifying biodiversity and ecosystem functioning. Although the negative impacts on individual taxa and processes are well documented, a comprehensive understanding of how ecosystem integrity responds to high herbivore densities remains limited. This study addresses this gap through an extensive herbivore‐density manipulation experime...
Wildfire smoke and antimicrobial resistance: A hidden link demanding global attentionNARA Subscribed
Wildfire smoke represents an underrecognized yet potentially important contributor to the dissemination of antimicrobial resistance (AMR). As wildfires increase in frequency and intensity due to climate change, they release vast amounts of PM 2.5 , particles with the potential to transport antimicrobial-resistant microorganisms and genetic elements across long distances. These severe air pollution events create multifactorial...
Mapping Bone Mineral Density Across Sport Modalities in Young Adults: A Scoping ReviewNARA Subscribed
Bone mineral density (BMD) is a key indicator of bone health, influenced by factors like exercise or energy availability. While exercise generally benefits BMD, sports with varied, dynamic movements (team/power-based sports) seem more effective than endurance modalities, characterized by repetitive, cyclic movements with low intensity. Thus, this scoping review aimed to examine and reflect on whole-body, spine, and femoral nec...
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...
Biological approaches to mitigate heavy metal pollution from battery production effluents: advances, challenges, and perspectivesNARA Subscribed
Battery production generates effluents containing various pollutants, predominantly heavy metals such as lead (Pb), cadmium (Cd), nickel (Ni), copper (Cu), zinc (Zn), and chromium (Cr), which represent a serious risk to human health and the environment. Given their persistence, toxicity, and mobility in ecosystems and biota, heavy metals can bioaccumulate and, in some cases, enter the food chain. With this context in mind, thi...
Tropical lakes as a novel source of oleaginous yeasts with lipid profiles for biodiesel, oleochemical, and nutraceutical applicationsNARA Subscribed
Oleaginous yeasts have emerged as promising microbial cell factories for lipid production, offering sustainable alternatives to traditional sources of biodiesel and nutraceuticals. In this study, the lipid accumulation potential of yeast strains isolated from two freshwater aquatic ecosystems in Cali, Colombia, was evaluated to identify novel candidates for biotechnological applications. A total of 56 strains were tested for t...
Analysis of nonsynonymous SNPs in candidate genes that influence bovine temperament and evaluation of their effect in Brahman cattleNARA Subscribed
Background Temperament is an important production trait in cattle and multiple strategies had been developed to generate molecular markers to assist animal selection. As nonsynonymous single nucleotide polymorphisms are markers with the potential to affect gene functions, they could be useful to predict phenotypic effects. Genetic selection of less stress-responsive, temperamental animals is desirable from an economic and welf...
