“…We obtained individual locations for 85 animals (77.27% of the total) through field research (Silveira, 2004;Azevedo and Murray, 2007;Cavalcanti and Gese, 2009;Onuma et al, 2016;Devlin, 2019), with GPS collars for 64 individuals and VHF collars for 21 individuals. For these individuals, we estimated centroids of home ranges based on the 100% Minimum Convex Polygon method (Mohr, 1947) using the Feature to Point tool in ArcGIS 10.1 (ESRI, Redlands, CA, USA).…”

“…Seven male and six female jaguars were captured between December 2011 and April 2016 as part of concurrent studies (Morato et al 2016;Miyazaki et al, 2016;Cardoso et al, 2020) approved by Instituto Chico Mendes de Conservação da Biodiversidade (SISBIO number 30896-3). The jaguars were captured using foot snares and immobilized with tiletamine and zolazepam (10 mg/kg).…”

Energetic subsidies between terrestrial and aquatic ecosystems can strongly influence food webs and population dynamics. Our objective was to study how aquatic subsidies affected jaguar (Panthera onca) diet, sociality, and population density in a seasonally flooded protected area in the Brazilian Pantanal. The diet (n = 138 scats) was dominated by fish (46%) and aquatic reptiles (55%), representing the first jaguar population known to feed extensively on fish and to minimally consume mammals (11%). These aquatic subsidies supported the highest jaguar population density estimate to date (12.4 per 100 km2) derived from camera traps (8,065 trap nights) and GPS collars (n = 13). Contrary to their mostly solitary behavior elsewhere, we documented social interactions previously unobserved between same-sex adults including cooperative fishing, co-traveling, and play. Our research demonstrates that aquatic subsidies seen in omnivores can be highly influential to obligate carnivores leading to high population density and altered social structure.

“…Antibodies to CDV, canine parvovirus and rabies virus have been detected in jaguars from Brazil. However, the impact of these diseases on the population dynamics of free-living jaguars remains unknown (Nava et al 2008;Furtado et al 2013;Onuma et al 2016).…”

Invasion of humans and dogs into the jaguars’ habitat opens the way for future negative events. Dog predation by jaguars has only been recorded anecdotally, despite the high risk of pathogen transmission and the potential conflict due to pet predation. In this study, we document jaguar attacks on dogs in Mahahual, Quintana Roo, Mexico, a tourist town in the Mexican Caribbean. In addition, we describe an initiative designed to prevent jaguar persecution by constructing night houses for dogs at the most recent attack sites. A total of 20 attacks were recorded in the last nine years, most of them fatal (60%) on medium-sized dogs (70%), at night (95%) and during the dry season (65%). Half of the attacks occurred in the north of Mahahual´s coastline and the other half in the south. Attacks in the south were concentrated between 0 to 10 km away from the village, while in the north they were dispersed over distances between 0 and > 30 km. Thirty-eight night houses were constructed covering almost 45 km of the 135 km of Mahahual’s coastline. Further research is required to understand the importance of dogs in the jaguar diet and the impact of dog predation on the health and disease ecology of jaguar populations.
