“…Esta serie de resultados sugieren cierta sensibilidad de la especie felina ante la destrucción y fragmentación de sus hábitats (15,137) y sus corredores naturales, (128) ya que se han reducido las subpoblaciones de jaguares, afectando su abundancia y su distribución a nivel local, regional y continental. (3,(139)(140)(141) Diversas investigaciones basadas en información de campo con fototrampeo, (47,70,73,120,137,142) con telemetría, (35,60,87) y registros recopilados o publicados (48,107) modelaron diversos escenarios para las subpoblaciones del felino, con lo cual aportaron mayor evidencia a la hipótesis de que las poblaciones se ven afectadas negativamente por el desarrollo de las actividades antropogénicas mal planeadas y ejecutadas bajo esquemas carentes de sustentabilidad. Las actividades humanas que representan la principal amenaza a la permanencia del jaguar son la ganadería, la construcción de presas y carreteras y la deforestación de los bosques.…”

“…(130) A pesar de ello, los jaguares pueden sobrevivir en paisajes dominados por actividades agropecuarias, pero que se integren por una red de parches de vegetación natural conservadas que integran al final un corredor biológico que permite la conexión entre los jaguares, sus presas y el resto de la fauna, entre estos co-rredores están los ambientes riparios, humedales (120) y las montañas o terrenos accidentados que permiten la permanencia y el resguardo de jaguares y sus presas. Otro factor de riesgo corresponde a la pérdida de inviduos por atropellamientos en carretera; (139,144) sin embargo, es necesario realizar investigaciones en todos los temas mencionados considerando escalas locales y monitoreos permanentes para evaluar con mayor profundidad estos supuestos.…”

A scoping review was conducted to map, summarize, and understand the extent of evidence on jaguar (Panthera onca) food resource use and its interaction with humans. A total of 105 studies were identified in electronic databases: 57 analyzed jaguar food resource use, and 48 described jaguar interactions with humans. The studies were published in 51 journals, mainly in English, from 1993–2021 in 14/19 countries where jaguars live. The evidence demonstrated the variability and prey consumption of the jaguar; there are contrasting results regarding the diversity of prey consumed. The frequency of livestock predation was found to be related to the abundance and availability of natural prey and the distance of ranches from the jaguar habitat. The interaction of the jaguar with humans presented an interesting and contrasting picture, since the perception of the jaguar varied depending on the sociocultural context and the study site. The results showed a negative effect of human activities on the distribution and density of the feline, and there was evidence of poaching and attacks on humans, although the information was insufficient to determine the causes in depth. More research and dissemination are needed on these issues at the local level in the regions where the jaguar lives, as these are the areas where decisions and actions are needed to conserve the jaguar in coexistence with communities and livestock.

“…Large mammalian carnivores are vital for the maintenance of biodiversity and ecosystem function and serve as indicators of ecosystem health (Ripple et al, 2014; Wolf & Ripple, 2016). However, human pressures in developing countries pose unprecedented threats to large carnivores (Alvarenga et al, 2021; Ceballos et al, 2021), predominantly through habitat transformation and prey loss (Sandom et al, 2017). Understanding the effects originating from these anthropogenic actions is essential for the conservation and management of large carnivore populations, particularly in areas undergoing intensive degradation.…”

Human pressures have increasingly placed keystone species, such as large cats, under threat. Together with forest loss, prey depletion is one of the main threats to the survival of jaguars (Panthera onca) and pumas (Puma concolor) throughout the Neotropics. Generally, primates are not considered main prey for jaguar and puma, and their inclusion in the diet could be indicative of ongoing prey species decline. Here, we investigate the effect of habitat type and disturbance on primate predation by large cats. Surveys took place during the dry seasons (March to June) of 2010 and 2011, covering a total of 608.5 km across 24 localities in the Uxpanapa Valley, Mexico. We found 65 felid scat samples with the aid of a wildlife scat detection dog, and then examined them to identify predator species and classify the prey remains they contained. Primates represented the most frequent prey (35%) for both jaguar and puma in our study site and constituted approximately half of the biomass consumed by these felines in the area. Primate remains were more likely to be found in scats surrounded by the lowest percentage of conserved forest or in areas surrounded by more villages, showing the potential effects of human activities on these species' populations. The high proportion of primates found in scats within our study site could be an early indication that populations of ungulates and other “typical” prey are beginning to collapse, and urgent conservation interventions are needed for both large cats and primates before they become locally extinct.Abstract in Spanish is available with online material.
