Abstract:
From June 2017 to September 2018, an infrared camera-trapping survey was used to study the activity rhythm of ungulate species in Baishuihe National Nature Reserve, Sichuan. The results showed that: (1) Six ungulates species were found in the nature reserve, namely
Budorcas taxicolor,
Naemorhedus goral,
Capricornis sumatraensis,
Moschus berezovskii,
Elaphodus cephalophus and
Sus scrofa. Relative abundance analysis results showed that the highest were
Naemorhedus goral (RAI=42.9) and
Elaphodus cephalophus (RAI=32.6), which were significantly higher than other species. The rest were
Moschus berezovskii (RAI=13.2),
Capricornis sumatraensis (RAI=4.8),
Budorcas taxicolor (RAI=3.8), and the least was
Sus scrofa (RAI=2.7).(2) On the annual activity pattern,
Naemorhedus goral was similar to
Elaphodus cephalophus,
Budorcas taxicolor was similar to
Sus scrofa, and
Moschus berezovskii deer had the strongest activity in May, and
Capricornis sumatraensis had the strongest activity in August. (3) The daily activity rhythms of the 6 ungulates showed that the daily activity rhythms of
Naemorhedus goral and
Elaphodus cephalophus were relatively similar, with the peak time of activity at 6:00–10:00 and 18:00–20:00. The activity peak time of
Moschus berezovskii appeared at 20:00–22:00;
Capricornis sumatraensis appeared at 6:00–8:00;
Budorcas taxicolor appeared at 8:00–10:00;
Sus scrofa appeared from 14:00 to 16:00. The activity rhythms of the 6 ungulates changed with the change of seasons. (4) According to the nocturnal behavior survey, among all six animal species,
Moschus berezovskii was a typical nocturnal animal,
Elaphodus cephalophus was not obvious, and
Budorcas taxicolor,
Naemorhedus goral,
Capricornis sumatraensis,
Sus scrofa had no obvious nocturnal behavior.
