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.
