| Abstract |
The influence of sympatric large animals on the sleeping behavior of primates in the wild is still largely unknown. In this study, we observed behaviors of wild Japanese macaques (Macaca fuscata yakui) at their sleeping sites, using a highly sensitive video camera. We found evidence of nocturnal interspecific interactions, such as agonistic interactions, between Japanese macaques and sika deer (Cervus nippon yakushimae). Deer approached sleeping clusters of macaques, which slept on the ground, to eat their feces or unidentified materials near the sleeping clusters, and as a result, the macaques were often quickly displaced from their sleeping site. There was a significant difference in the occurrence of macaque-deer agonistic interactions between seasons. Our results suggested that the size of the sleeping cluster, the number of adult macaques in the cluster, and the existence of adult males in the cluster did not influence the occurrence of the agonistic interactions. Finally, we discuss the influence of this interaction on macaques and speculate on the influential factors leading to nocturnal coprophagy of macaques' feces by deer. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 November 2012.
All research outputs
#18,319,742
of 22,684,168 outputs
Outputs from Primates
#900
of 1,014 outputs
Outputs of similar age
#150,267
of 163,882 outputs
Outputs of similar age from Primates
#4
of 4 outputs
Altmetric has tracked 22,684,168 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,014 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 17.3. This one is in the 3rd percentile – i.e., 3% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 163,882 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 4th percentile – i.e., 4% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 4 others from the same source and published within six weeks on either side of this one.
