The application of infrared camera in mammal research in Guanyinshan Nature Reserve Shaanxi
Since July 2009, the total 18 cameras were installed in the Guanyinshan Nature Reserve ( GNR) , Shaanxi Province. During our 24 months' monitoring from August 2009 to July 2011, we have collected a total of 1 755 mammal photos. The results show (1) a total of 22 mammal species were photographed. The first 6 species selected for analysis based on a relative abundance index (RAI) were Budorcas taxicolor, Naemorkedus goral, Elaphodus cephalophus, Sus scrofa, Capricornis sumatraensis and Muntiacus reevesi; their total percentage reaches 86. 04% . (2) The monthly RAI (MRAI) for the whole year varies among months. The greatest value of MRAI is acquired in July and the lowest in February. (3) Three of the six selected species demonstrated similar daily activity patterns, which has two peaks, one at dawn and one at dusk. The daily pattern of Naemorhedus goral also has two peaks, but they differe from those of the previous three species. The daily activity pattern of Sus scrofa shows a peak at noon and Capricornis sumatraensis was less active at the period of 10:00 -16:00. (4) The NRAI gave a clear indication of variation in nocturnality among the 6 species. Capricornis sumatraensis was most active at night and Sus scrofa was opposite.
