Title: STUDIES ON THE FOOD RESOURCE NICHES OF PLATEAU PIKA AND DAURIAN PIKA
Abstract:The sympatric coexistence of plateau pika(Ochotona curzoniae)and daurian pika(O,daurica)was found by researchers,at Niannuosoma area of Gangcha county.Qinghai province(is located 37°10'N. 99°40'E).Thi...The sympatric coexistence of plateau pika(Ochotona curzoniae)and daurian pika(O,daurica)was found by researchers,at Niannuosoma area of Gangcha county.Qinghai province(is located 37°10'N. 99°40'E).This paper presented the relationship between the niches of two spesies of the pikain common habitat,from utilization of food resources. The experiment showed the nichebreadth is 0.474 4 for plateau pika and 0. 496 4 for daurian pika,respectively(PSmeasurement),in the niche dimension of the food resources. The niche overlap was.thelargest (0.809 1,FT measurement)in the niche dimension of food resources utilizationspectrum between plateau pika and daurian pika.It was provable that the interferencecompetition had been more intensity between two species of the pikas.Read More
