Pretty clever comment, made me think if this is the exact same thing as human stress eating.

It's preparing your body, energy requirements wise, for potential future danger. Even noise, anything 30 Dbs or above, causes a stress response in the body and will lead to a cascade of issues.

Same here. Eating or taking a nap are two most effective ways of dealing with stress I found that don't involve any kind of magic pills.

#9tldr: Pumas that are scared off their food by humans are still hungry and go and kill another deer, which might not be so good for the pumas and might help scavengers. Isn't this somewhat obvious?

Well, there are a lot of interesting things in the paper. To me, the biggest one is that they could only find this effect in female pumas. Apparently male pumas roam a range approximately 3 times as large as female pumas, and therefore must be much more mobile to maintain their territory - average lingering time at a kill site was estimated to 7 hours shorter (2.86 vs 2.56 days) for males than females in areas with minimal human presence. The suggestion from the authors is that the since males are already under pressure to be mobile, that they were already spending close to the minimal amount of time required at a kill site to extract sufficient energy.
Other things of interest is that we can actually see variance in behavoir increasing as human density increases. The error bars (standard deviation) on time spent at kill sites (or really doing anything) open right up the moment housing appears.
