“…We did not study seasonal differences in diet and prey availability between dry and rainy seasons because previous experience during heavy rains resulted in camera malfunctions and scats being washed away. Other limitations in this study include the low number of scats collected, although this is consistent with estimated population densities of up to 3.6 jaguar and 5.2 puma for Eden (Ávila-Nájera et al, 2015).…”

“…The camera trap locations were selected using the CENJAGUAR (Chávez et al, 2007), which requires at least nine adjacent 9 km 2 study plots each containing two or three camera stations, with at least one station per plot having two cameras directly facing each other. Cameras were placed 1.5-3 km apart along a series of forest trails, firebreaks and dirt roads of differing lengths (8-16 km) and their locations are shown in figure 1 and described in Ávila-Nájera et al (2015). In 2011, there were 22 camera stations operating continuously for 82 days, with 24 cameras operating over 72 days in 2012.…”

Jaguar (Panthera onca) and puma (Puma concolor) diets in Quintana Roo, Mexico. A study was carried out for two years in Northwest Quintana Roo, México, using scat analysis to determine the diet and prey preferences of pumas and jaguars. Cat species and gender were determined using molecular techniques (rapid classificatory protocol: polymerise chain reaction, RCP-PCR), and prey abundance was estimated from camera trapping. The scats contained remains from 16 wild mammal species, but there was no evidence of livestock or other taxa. The diet breadths of jaguar (0.32) and puma (0.29) indicated a high degree of prey specialization, which combined with their dietary overlap (Pianka index 0.77) suggested competition between them. However, both felids showed a preference for red brocket deer Mazama temama, and frequently consumed collared peccaries Pecari tajacu. The importance of such large ungulates in the felids' diets is similar to the expected patterns of wild meat consumption in rural areas of the Northern Yucatan Peninsula. Therefore, future conservation management plan initiatives should involve local rural communities in the management of sustainable hunting, considering these ungulates are also the felid prey species.

“…The number of cougars identified during the four years was high, but the density in the study area varied from 1.85-5.17 (Ávi-la-Nájera, Chávez, Lazcano-Barreto, Pérez-Elizalde, & Alcántara-Carbajal, 2015). This value resulted similar to other cougar distribution sites, for example, 1.9 in Venezuela, 2.4-4.9 in Belize, or less than others sites like 6.13 in Brazil, or 12.4-19.4 in Bolivia (Laundre & Hernández, 2010).…”

Worldwide big cats are at risk of extinction, and anthropogenic factors and natural habitat disturbances represent the biggest threats for their survival. It is essential to know the natural resources use by these predators and the way these big felids can adapt to changes. It is unknown how the puma (Puma concolor) selects and uses resources, what environmental factors determine its presence and how this species is affected by natural disturbances in Mexican tropical forests. This study was performed in the Eden ecological reserve and surroundings, in the North of Quintana Roo, Mexico, an area dominated by tropical semideciduous (medium forest) and secondary forest (acahual). Camera samplings were carried out during 2008, and from 2010 to 2012. Habitat variables, activity patterns and species associations were also spatially and temporally analyzed using achi-squared test and overlapping coefficients. General Linear Models (GLM) were used in order to determine which variables influence the presence of cougars in the study area. Cougars used vegetation and paths in different proportions as the availability of these resources. The years with more changes (P < 0.05) were 2008 and 2011. This predator was active throughout the day, but changed its activity patterns over the years. The cougar was spatio-temporally associated with six mammals and two big terrestrial birds: Pecari tajacu (∆ = 0.52), Meleagris ocellata (∆ = 0.55), Crax rubra (∆ = 0.58), Didelphis sp. (∆ = 0.64), Mazama temama (∆ = 0.66), Leopardus pardalis (∆ = 0.68), Dasypus novemcinctus (∆ = 0.73) and Panthera onca (∆ = 0.87). After testing 90 GLM models, the model with a lower AIC value described the activity patterns of prey and co-predators. The vegetation and water in the reserve were important variables for the cougar. However the variables that determined and modified the presence of the species were activity patterns of co-predators and the potential preys. The factors that negatively affected the presence of the species were fire, human presence, and habitat displacement to less favorable habitats to avoid jaguar. Rev. Biol. Trop. 66(1): 78-90. Epub 2018 March 01.Key words: acahual, activity patterns, associated species, cougar, environmental variables, fair, human effect, tropical semideciduous forests.Carnivore decline and local extinctions are tragic, and they can produce effects that reverberate across entire ecosystems (Hunter, 2011). To know the environmental variables that affect the ecological role of wildlife is a clue about factors influencing carnivore population size and dynamics, and the role of resource limitation (a bottom-up process; Laundre & Hernández, 2010). For conservation purposes, it is essential to determine how species respond to habitat disturbance; for example, fire has a strong influence on forest structure; it has been associated with the simplification of forest structure (Collins, 2012) and animal communities can be affected by fire via direct mortality, or indirectly through the alteration of habitat r...

“…Aunado a esto, las densidades estimadas en cada región podrían estar determinadas por disturbios climáticos y antrópicos (e. g. incendios, huracanes), tipo de hábitat (e. g., bosques de pino, bosques tropicales, selvas perennifolias, matorrales), por característi-cas del paisaje (e. g., áreas con pérdida y modificación de sus coberturas forestales y áreas con algún grado de protección), y por disponibilidad de recursos alimenticios, ocasionando que los estudios realizados en otras áreas y tipos de hábitats no sean comparables (Dillon y Kelly 2007. Ávila-Nájera et al (2015), realizaron un estudio en nuestra misma zona de estudio durante los años 2008, 2010, 2011, y 2012, en la que reportan una densidad de 13.86 ind/100 km 2 para el 2010 y para el mismo periodo de muestro del presentado en nuestro estudio. Sin embargo, para los años posteriores reportan una densidad por debajo de la reportada para el 2010.…”

Ocelots are at risk of extinction due to anthropogenic pressures. Therefore, it is essential to generate information about this species in zones with climatic and anthropogenic pressures in order to determine appropriate measures for their conservation. Our goals were to determine population density, relative abundance, activity patterns and minimum observed home ranges of ocelots in northern Quintana Roo, Mexico. During 2008, we conducted systematic sampling for 60 days using camera-traps in Northern Quintana Roo, Mexico. The camera-trap grid covered an area of 81 km 2 and included El Eden Ecological Reserve. We placed 27 camera-trap stations: 18 with a single camera and 9 with two. Camera-trap stations were spaced approximately 1 kilometer apart. Our total sampling effort was 2160 trap-days. We registered 12 individual ocelots: five males, six females, and one of undetermined sex. The density estimated using CAPTURE program was 14 ind/100 km 2 , while the density estimated for each sex separately was 7 ind/100 km 2 . We estimated a relative abundance index of 1.85 ± 0.27 in tropical forest, 1.11 ± 0.22 in secondary vegetation and 0.185 ± 0.09 in savannah. The ocelot was more active at night. The minimum observed home range of male ocelots was larger than that of females, 4.63 km 2 and 1.80 km 2 respectively. We presented some ecological data of ocelot in El Eden Ecological Reserve and its area of influence. These results constitute an important baseline to make a comparison in areas adjacent that have strong climatic and anthropic pressures. Finally, the area is one of the most important for the conservation of ocelot in México.El ocelote está en riesgo de extinción debido a factores antropogénicos. Por lo tanto, generar información sobre esta especie en zonas con impactos climáticos y antrópicos se convierte en esencial para determinar medidas adecuadas para su conservación. Nuestros objetivos fueron determinar la densidad de población, abundancia relativa, los patrones de actividad y áreas mínimas de acción del ocelote en el norte de Quintana Roo, México. Durante el 2008 se realizó un muestreo sistemático de 60 días mediante foto-trampeo en el norte de Quintana Roo. El diseño se implementó para muestrear un área de 81 km 2 , que incluye a la Reserva Ecológica El Edén. Se colocaron 27 estaciones de cáma-ras trampa, 18 fueron sencillas y 9 dobles, cada estación de foto-trampeo tuvo una separación aproximada de 1 kilómetro. En total tuvimos un esfuerzo de muestreo de 2160 días/trampa. Se registraron 12 ocelotes, cinco machos, seis hembras y un individuo sin determinar el sexo. La densidad estimada de ocelotes usando el programa "CAPTURE" fue de 14 ind/100 km 2 , mientras que la densidad estimada para machos y hembras fue de 7 ind/100 km 2 . El índice de abundancia relativa fue de: 1.85 ± 0.27 para selva mediana, 1.11 ± 0.22 para vegetación secundaria y 0.185 ± 0.09 para sabana. El ocelote presentó su mayor actividad por la noche y el área de acción de los machos fue mayor al de las hembras, 4.63 km 2 y 1.80 km ...
