Abstract：To explore the coexistence mechanisms between Sus scrofa and Elaphodus cephalophus distributed in the same region,Sus scrofa and Elaphodus cephalophus in the Hubei Mulinzi National Nature Reserve were monitored using infrared camera technology from January to December in 2020,and the data were analyzed using kernel estimation and overlap calculation methods.The results indicate:①There were differences in the daily activity rhythms of Sus scrofa during the rainy and dry seasons.In the dry season,Sus scrofa exhibited a bimodal activity pattern,with activity intensity peaks occurring between 02:00-04:00 and 17:00-19:00.During the rainy season,they showed a multimodal activity pattern,with the main activity intensity peaks occurring between 00:00-06:00 and 18:00-20:00,and secondary activity intensity peaks between 07:00-08:00 and 09:00-12:00.Compared to the dry season,the rainy season showed not only an increase in the number of activity intensity peaks but also an enhancement in activity intensity.② Also,there were differences in the daily activity rhythms of Elaphodus cephalophus during the rainy and dry seasons.Both seasons exhibited the multi-peak activity patterns.There were the main activity intensity peaks occurring between 08:00-10:00 and 18:00-19:00,and the secondary activity intensity peaks between 00:00-01:00 and 02:00-04:00 in the rainy season.The main activity intensity peaks in the dry season were concentrated between 00:00-04:00 and 18:00-20:00,with secondary activity intensity peaks between 06:00-08:00 and 12:00-14:00.Compared to the rainy season,the dry season showed an enhancement in activity intensity.③ The overlap of activity patterns between Sus scrofa and Elaphodus cephalophus was higher during the rainy season and lower during the dry season.The two species achieved resource sharing and avoided competition by adjusting their activity times.This study provided a theoretical basis and scientific support for the protection and management of co-occurring species within the Hubei Mulinzi National Nature Reserve.
