Temporal niche and daily activity patterns of sympatric leporids in active burrows of Mapimi Bolson tortoise
Diferential temporality of daily activity patterns allows the coexistence of related species. This strategy is believed to be used by sympatric leporids black-tailed jackrabbit (Lepus californicus) and desert cottontail (Sylvilagus audubonii) in the Mapimi Biosphere Reserve in Mexico. Using trap cameras, we recorded the temporal niche and nine specifc patterns of daily activ ity from both species in a shared microhabitat (burrows of Mapimi Bolson tortoise, Gopherus favomarginatus), from April 2014 to January 2016. Although the degree of temporal niche overlap is high (Pianka=0.9781; Czechanowski=0.8769), only 0.21% of the total records were simultaneous sightings of individuals of L. californicus and S. audubonii within the same burrow. In addition, there were diferences in the diurnal activity peaks of these leporids (L. californicus=7:00 a.m. to 8:00 a.m., S. audubonii=6:00 a.m. to 7:00 a.m.). Six specifc activity patterns (Entering, Exiting, Grooming, Feeding, Alert, and Evasion) were signifcantly diferent, according to the Watson’s U2 two-sample test for cyclic distributions (critical value=0.187, p=0.05). Our results suggest that the temporary partition of specifc daily activities between the two leporids can contribute to their coexistence in this microhabitat.
