Scientists track the scratches made by jaguars and pumas

Penelitian - Scientists trace the tracks of jaguars and pumas in detail that have been mysterious. An international team of researchers from Spain, Mexico, Brazil and the United States of America conducted a survey examining the general hypothesis of scratches made by felids to communicate with other individuals in Mexico, Belize and Brazil.

Communication plays an important role in mammal populations and communities that provide information about the existence, identity, health or social status of individuals of the same or different species or location of eating places within territories and territorial boundaries.

Mammals use visual, tactile, vocal or olfactory signals to communicate with each other or to mark the area and especially in carnivorous mammals, marking the scent of using urine, secretions, scratching ground, rubbing, or faeces have been well documented.

The team of scientists walked slowly while searching for scratches and found a total of 269 faecal strokes along 467 km of lines surveyed with a discovery level of 0.576 scratches per km and rarely found scratches across the country. Felid chose a site largely covered by leaves and located on a less wide, clean and less used path.



Scraping is a behavior that often occurs in the largest felids of America and seems to indicate some specific areas within the region and the data indicates that they use for interpersonal communication, but it seems that the high scratching behavior on the podas is not related to the presence of the jaguar.
