Además de la pérdida de cobertura boscosa, el conflicto con seres humanos ha sido la causa principal de la disminución de la población. Se recopilaron datos de un mínimo de 293 jaguares que fueron matados entre los años 1989 y 2016, casi siempre en represalia por depredación de animales domésticos. Para mitigar el conflicto y contrarrestar sus efectos en la población de jaguar, es necesario trabajar con los diferentes actores, en particular el gobierno, los ganaderos y las comunidades locales, e implementar varias estrategias de conservación a corto y largo plazo.

We present several new records across Panama resulting from camera-trapping surveys and direct observations. Camera-trap photos taken for the first time in Panama in 2012 and 2015, together with the new sightings, confirm the species’ broad and continuous distribution along the Panamanian Isthmus. Our data reveal the importance of the region for bush dogs, but given the rapid depletion of forest habitat and the decline of prey species, emphasis should now be placed on developing quantitative indicators for evaluating population trends across Panama. Moreover, conservation measures based on ecological information in the tropical forest should be taken to enable the long-term persistence of the species in Panama.

Coiba Island is located on the South Pacific side of Panama, in the Chiriquí Gulf. It is a continental island and the biggest in the Mesoamerican region of the Pacific, it has an area of 503 km². This is a preliminary survey to identify basic feeding behaviour that could be measured in the future as a part of our ethogram to study C. imitator, as part of our long-term project on Coiba Island. We identified four feeding skills by C. imitator outside the forest: Hammering shells or skilled pounding, removing rocks, eating mangrove fruits, and pounding Cocos nucifera on an anvil. Using anvils seemed to be the most effective method to obtain food spending 51% of the time eating using this technique and only 28% moving to find a coconut, 18% invested in pounding the fruit, and just 3% on keeping vigil. Spending time outside the coast of a continental island seemed to be a benefical technique for C. imitator to survive. Further studies will be conducted by Fundación Pro-Conservación de los Primates Panameños (FCPP) to understand the predation-feeding-competition theory and its implications for foraging techniques by C. imitator in an island habitat.
