water use patterns of sympatric przewalski's horse and khulan: interspecific comparison reveals niche differences.acquiring water is essential for all animals, but doing so is most challenging for desert-living animals. recently przewalski's horse has been reintroduced to the desert area in china where the last wild surviving member of the species was seen before it vanished from china in the 1960s. its reintroduction placed it within the range of a close evolutionary relative, the con-generic khulan. determining whether or not these two species experience competition and whether or not such competition was ...201526161909
human activity dampens the benefits of group size on vigilance in khulan (equus hemionus) in western china.animals receive anti-predator benefits from social behavior. as part of a group, individuals spend less time being vigilant, and vigilance decreases with increasing group size. this phenomenon, called "the many-eyes effect", together with the "encounter dilution effect", is considered among the most important factors determining individual vigilance behavior. however, in addition to group size, other social and environmental factors also influence the degree of vigilance, including disturbance f ...201626756993
the incidence and species composition of gasterophilus (diptera, gasterophilidae) causing equine myiasis in northern xinjiang, china.a survey was conducted on the detection of the larval gasterophilus species in 90 equines via necropsy or after administering oral ivermectin in xinjian, china, from 2008 to 2013. all 90 (100%) equines were infested by larval gasterophilus, and 3723second instar larvae (l2) and 63,778 third instar larvae (l3) were collected from faecal samples and the digestive tract, a ratio of l2:l3=1:17. over 84.45% of the animals contained ≤1500 larvae and 7.78% had >2000 larvae. the highest totals of l2 and ...201626827858
