Mature cow weight (MWT), height (MHT), and body condition score (BCS) are economically important traits that significantly influence cowherd profitability by affecting maintenance feed requirements, which is the largest component of production costs. This study aimed to identify genomic regions, candidate genes, and pleiotropic variants associated with mature cow size traits in American Angus cattle, and to characterize their...

This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae , an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu River, and stomach contents of 134 specimens were analysed. The diet was predominantly c...

Background Despite advanced analytical methods and increasing data availability, most intensive care unit (ICU) prediction models rely on static measurements. However, longitudinal monitoring of biomarkers may better capture disease progression and support timely, individualized interventions within the framework of predictive, preventive, and personalized medicine (PPPM). Since the COVID-19 pandemic, interest in both static a...

Relatively little is known about the ranging patterns, diving behavior, or prey preferences of killer whales ( Orcinus orca ) in tropical latitudes. However, they are suspected to be prey‐generalists rather than the prey‐specialists that are typically found in high latitudes. In February 2025, we satellite‐tagged three killer whales from a pod of seven in Bahía de Banderas, Mexico. The tags transmitted for 8–41 days. The tagge...

Aim Anthropogenic changes alter predator–prey systems worldwide. Defensive behaviour is shaped by the costs and benefits for individuals, and we hypothesise that tail shedding, as an escape strategy, has a higher cost for animals in human‐modified environments compared to natural landscapes. Therefore, our central objective was to evaluate the effects of human footprint on the observed frequency of caudal autotomy in geckos. L...

The COVID-19 pandemic triggered unparalleled political, economic, and social ramifications, exacerbating global food insecurity (FI). To understand the overall impact of the pandemic and how different socio-economic groups were affected, we assessed prevalence and severity of FI in a sample of 18,997 households across seven countries in South America. We employed the Food Insecurity Experience Scale developed by the FAO. Our r...
