Shark populations worldwide are declining rapidly, primarily due to overfishing, habitat degradation, and mislabeling of seafood products, which exacerbates their exploitation and conservation challenges. This study investigates the presence of shark meat being sold under false labels as fish species in Ecuadorian markets, spanning both coastal and highland regions. Using primers derived from the nuclear ribosomal ITS2 region...

Most large felids are classified as solitary species, with only lions ( Panthera leo ) and cheetahs ( Acinonyx jubatus ) exhibiting social, collaborative behaviours. Herein, we present evidence of the formation of male coalitions by jaguars ( Panthera onca ), based on data from five studies conducted with camera trapping, GPS telemetry, and direct observations in the Venezuelan Llanos and Brazilian Pantanal. Out of 7062 male r...

All animals, including carnivores, adapt their daily activity duration and distribution to satisfy food demands, breed, or avoid mortality risk. We used the kernel density method to estimate daily movement activity levels and movement activity patterns of jaguars in Hato Piñero, in Venezuelan Western Llanos, based on 3,656 jaguar detection time records from two and a half years of camera trapping. Jaguars were active for 11.7...
