Puma concolor
Hello, community interested in science!
My name is Hugo Anselmo and I’m 23 years old. Some curiosities about me: my favorite food is carbonara; my favorite series is Euphoria; as a dedicated scout, my motivation is a quote from the founder of the Scouting, Robert Baden-Powell - “Leave this world a little better than you found it.”; my future objetive is the biggest cliché ever: be happy.
I did a graduation in Biology at the University of Aveiro and currently I’m doing a master degree in Ecology and Environment at the Faculty of Sciences of University of Porto. My main areas of interest are the Mastozoology and the Behavioral Ecology. Because of that, I’m doing my master's thesis, focused on the pumas (Puma concolor) behaviour, at REGUA (Guapiaçu Ecological Reserve), a NGO and a Private Natural Heritage Reserve), located in the state of Rio de Janeiro, Brazil.
The puma is the most widespread native land mammal in the Western Hemisphere, with a geographic range representing about 22,735,268 km2, extending from Canada to the southern tip of Chile. Furthermore, the puma is the second-largest species of felid on the American continent and the fourth-largest in the entire world.
To monitor the population, I use camera traps and it is necessary to distinguish the different animals from each other through their natural marks: eventual scars, the spots on the muzzle, the color of the nose and shape/twist of the tail.
A very interesting behavior strongly exercised by male pumas is the scrape-marking, a way of marking territory by scratching the ground with its hind legs. In addition to keeping other males away, marking also has the function of attracting females.

According to the bibliography, females smell the marks and can understand whether the male who marked is a dominant or a submissive one. Females prefer to mate with dominant males because that means their territory are bigger and, consequently, their offspring will be more protected. In some felids, the infanticide is common, meaning that the males can try to kill the cubs that are not from them, in an attempt to make females receptive to mating again, something that doesn't happen while they are still providing parental care for their cubs.

To facilitate the understanding of these interactions between the pumas, I created a comic called “Captain Hook’s crush” that can be read on REGUA's instagram in portuguese or in english - @reguabr.
