Abstract:

Resumen: Las Selvas Mayas de la Península de Yucatán, México, mantienen una de las poblaciones más importantes de jaguar (Panthera onca) al norte de su distribución. Sin embargo, la región está sujeta a grandes cambios en su cobertura forestal debido al desarrollo humano y agropecuario de los últimos años. Esto ha ocasionado una reducción en el hábitat del jaguar y por consiguiente un incremento en la incidencia de ataques al ganado doméstico por jaguares, debido a ello es necesario contar con información sólida sobre las áreas de conflicto humano-jaguar para ser consideradas durante los plane

Abstract:

AbstractThe global population of jaguarsPanthera oncahas decreased significantly since the beginning of the 20th century. Given the scarcity of demographic and biological information, estimating population parameters is critical for the design of conservation measures. The jaguar's elusive behaviour makes it impossible to estimate and monitor populations by direct observation. We propose a non-invasive genetic sampling approach and demonstrate its potential for large-scale monitoring. Sex identification was optimized for faecal samples of jaguars and other felids. We also optimized a set of 11

AbstractRemaining jaguar Panthera onca populations in the Atlantic Forest are restricted to eight regions, and all populations appear to be declining. We report on the status of one of the last populations in south-eastern Brazil. We monitored this population with camera traps during June 2005–January 2013 in Vale Natural Reserve. We estimated an abundance of 9 ± SE 1.98 jaguars (95% CI 9–17) and a population density of 3.22 ± SE 1.58 individuals per 100 km2 (95% CI 1.29–7.98).

Jaguar populations have declined dramatically in the last century. The Maya Biosphere Reserve (MBR) within the Selva Maya (SM) is a priority area for jaguar conservation. Influential factors in the jaguar seasonal distribution include the availability of surface water in wetlands such as the “aguadas” and the availability of prey. Aguadas are formed by isolated depressions in the landscape and serve as a water supply for wildlife during dry periods. The goal of this study was to describe the visitation patterns of jaguars to aguadas in a Tropical forest at Dos Lagunas Protected Biotopo, a core

Whether these factors are consistent with previous research on human–carnivore coexistence is unclear. To address this we estimated

The decline of the jaguar in the 1970s reflected the large trade in their skins.

However, habitat destruction and opportunistic killing continue. If the jaguar is to persist into the future, local people must be convinced that conserving jaguars has long-term benefits for them.

AbstractThe jaguar Panthera onca, a threatened species in Brazil, is losing suitable habitat as a result of agricultural expansion and other forms of land conversion, especially in the Cerrado biome. In the current context of habitat loss and fragmentation, a network of protected areas is paramount for the conservation of this species. We aimed to identify jaguar conservation units in the Cerrado, and propose a ranking of priority areas for the species in this region. We used the maximum entropy algorithm to model habitat suitability for the jaguar in the Cerrado, with nine uncorrelated enviro

Abstract:

The largest feline in the Americas and the third largest in the world, the jaguar is an apex predator in the food chain and a key species in the ecosystems where it occurs, developing important ecological functions in maintaining ecosystem balance. In Brazil, the Pantanal is considered an important refuge for the species, and protected areas such as the Taiamã Ecological Station (TES) are relevant for conservation of pristine ecosystem where the species persist. Thus, considering that this area is located in one of the regions with the highest concentration of this large cat in the Pantanal, t

AbstractOur objective in this study was to determine the density of the jaguar Panthera onca from camera-trap data, using an open population model, in a private protected natural area, the Northern Jaguar Reserve, and 10 adjoining cattle ranches in the state of Sonora, Mexico. The region is considered a long–term jaguar conservation unit. As well as being the most northerly recorded reproductive population of the jaguar, the arid habitat of this region is atypical for the species. During 16 months of sampling we identified 10 individual jaguars and the data met the three main assumptions of op

Three ways to detect felid presence were employed from August 2002 to May 2006: interviews, signs, and camera-traps. 478 records were obtained, from which 441 were from cougar and 37 from jaguar. These records included positive response in 118 of 140 interviews and 236 records of signs (mainly tracks and scats), and 124 photographs. Both felids preferred pine-oak forest habitats, with altitudes higher than 1800 m, distances between 3509 and 4377 m from road

Mobbing is a rarely observed anti-predation strategy used by group-living prey species whereby several individuals distract or harass a predator until it either ends the pursuit or leaves the area.

White-lipped peccaries and jaguars co-occur within the study area, a large-scale ecotourism and working cattle ranch in the Brazilian Pantanal.

Therefore, this work evaluated the behavior of two Panthera oncacaptive specimens, including their inactivity, during the evening/night period. The jaguars were filmed individually in different days, starting at 5:30 pm and finishing between 7:00 pm and 1:30 am, including non-feeding and feeding days.

Jaguars, Panthera onca (Linnaeus, 1758), and pumas, Puma concolor (Linnaeus, 1771) are the largest felids in the neotropics. Both can overlap in niche axes (time, space and prey), and are therefore potentially competing species. Segregation mechanisms presented by a low overlap in one of these axes of niche can facilitate the coexistence. Our aim was to analyze jaguar and puma temporal and spatial overlap for understanding their segregation mechanisms.
