Activity patterns and resource partitioning: seven species at watering sites in the Altun Mountains, China

引用

Journal of Arid Land 2018年第6期10卷 959-967页

作者： XUE Yadong LI Jia SAGEN Guli ZHANG Yu DAI Yunchuan LI Diqiang Institute of Forest Ecology Environment and ProtectionChinese Academy of ForestryBeijing 100091China Administrative Bureau of Xinjiang Lop Nur Wild Camel National Nature Reserve Urumqi.830011China

As part of a larger project to examine the richness and distribution of wildlife in Kumtag Desert area, we conducted camera trapping surveys during the period 2010–2012 at seven watering sites in an arid region of the Altun Mountains in western China. Information on activity patterns of the wild bactrian camel (Camelus ferus), kiang (Equus kiang), goitered gazelle (Gazella subgutturosa), argali (Ovis ammon), blue sheep (Pseudois nayaur), red fox (Vulpes vulpes), and wolf (Canis lupus) was obtained. We found that the wild camel, kiang, goitered gazelle, argali, and blue sheep were predominantly diurnal at watering sites, whereas red fox and wolf were nocturnal. Five herbivores partitioned the use of watering sites in a temporal manner to minimize the risk of predation by carnivores. The wild camel was the dominant herbivorous species at the watering sites. The kiang, goitered gazelle, argali, and blue sheep displayed adaptive water use by altering spatial or temporal patterns based on the presence or absence of wild camel, to minimize the risk of interspecific strife. These results are suggestive of the differences in activity patterns that might modulate water partitioning by different species, and provide insights for the development of conservation strategies for integrated species and decisions regarding water development in the Altun Mountains.

Lowland tapir distribution is described in northwestern Bolivia and southeastern Peru within the Greater Madidi-Tambopata Landscape,a priority Tapir Conservation Unit,using 1255 distribution points derived from cam-era trapping efforts,field research and interviews with park guards from 5 national protected areas and hunt-ers from 19 local communities.A total of 392 independent camera trapping events from 14 camera trap surveys at 11 sites demonstrated the nocturnal and crepuscular activity patterns(86%)of the lowland tapir and provide 3 indices of relative abundance for spatial and temporal *** rates for lowland tapirs were not significantly different between camera trapping stations placed on river beaches versus those placed in the *** tapir capture rates were significantly higher in the national protected areas of the region versus in-digenous territories and unprotected portions of the *** rates through time suggested that low-land tapir populations are recovering within the Tuichi Valley,an area currently dedicated towards ecotourism activities,following the creation(1995)and subsequent implementation(1997)of the Madidi National Park in *** on our distributional data and published conservative estimates of population density,we calcu-lated that this transboundary landscape holds an overall lowland tapir population of between 14540 and 36351 individuals,of which at least 24.3%are under protection from national and municipal *** such,the Great-er Madidi-Tambopata Landscape should be considered a lowland tapir population stronghold and priority con-servation efforts are discussed in order to maintain this population.
