In the past few weeks I’ve been out in the field in Caatinga in eastern Brazil studying the diet of a female puma. This is the first time that puma has ever been studied in this biome.
What I’ve done is I have visited sites where she has stayed for a little bit of time in order to see what she has done there. Was she eating something or just resting? The most important thing I have been wanting to find out is how much does she prey on domestic animals. This is very important because there is a lot of poaching of jaguars and pumas since they do kill and eat livestock. But how common is it? Are the farmers exaggerating or is it a real problem? And what could be done to alleviate this conflict?
The field work was very difficult due to the harch environment of Caatinga. The plants are thorny and the vegetation is thick. Many plants have fish-hook thorns that would rip a normal t-shirt into pieces in a matter of hours. Also, for each step you take, there is at least one plant there to trip you. When going off-track, we progressed about 500 meters per hour. Luckily, to my help was Ananias, a local who came to be my field assistant. With his help I could use the many trails that exist which helped a lot.
Ananias and I trekked on average ten hours per day in sweltering temperatures in this rough environment visiting these cluster sites. The temperature where we worked averaged about 30-35 degrees C in daytime. Add to this the clothes necessary to protect against the vegetation and it soon becomes very warm.
Some of the interesting things about working in this environment is trying the local fruits that grow ever so seldom. Running in to a mango tree after trekking a long distance was a great experience and I think that I have never tasted mangoes that sweet. There have been a lot of other interesting fruits, too, which I can’t even pronounce the names of.
There have been a lot of interesting finds in this study. This is the first time ever that this species has been studied in this biome, making it a pioneering study. I will now get down to analyzing the results. Hopefully this will lead to us being more able to protect pumas and jaguars in this area in the future – so that we can have a green planet full of life.
