An evaluation of multi‐species occupancy models with correlated species occurrences
Abstract Multi‐species occupancy models for estimating the effects of environmental covariates on species occurrences while accounting for the effects of false‐negative errors in detection were developed more than 20 years ago. Only recently have these models been extended to include correlations in occurrence between species. Tobler et al.

The links between microbial functional diversity and ecosystem stability remain unclear. Microbial functions vary more temporally than spatially, and ecosystem stability is decoupled from functional diversity in agroecosystems. ABSTRACT Functional diversity in producers and consumers can not only promote ecosystem functions but also impart additional ...

The Impact of Livestock on the Spatiotemporal Activity of Ungulates in Western Sichuan, China
Grazing is a widespread land use practice with significant implications for biodiversity and ecosystem functioning. Wild ungulates, as key components of terrestrial ecosystems, play a vital role in maintaining ecosystem health.

MtDNA D-loop sequences and cranial morphometrics were used to analyze the phylogenetic relationships of bharal (Pseudois nayaur szechuanensis) populations. The habitat preferences of bharal were also investigated in Helanshan, Ningxia.

Relative influence of wild prey and livestock abundance on carnivore‐caused livestock predation
Conservation conflict over livestock depredation is one of the key drivers of large mammalian carnivore declines worldwide. Mitigating this conflict requires strategies informed by reliable knowledge of factors influencing livestock depredation.

哺乳动物的毛有保暖、保护身体、散热和感觉震动等功能。换毛是哺乳动物过冬的方式之一,岩羊(Pseudois nayaur)也具有换毛的现象。实验通过对冬、夏季节祁连山地区岩羊粗毛显微形态指标的测量,来对比祁连山地区岩羊不同部位粗毛在冬、夏季节的差异和共性。结果表明,岩羊粗毛髓质发达,除蹄部和腿部外,髓质指数保持在90%以上。此外,推测岩羊粗毛保温性能保持由躯干部向四肢端部递减的趋势,臀部保温性能最佳。腿部和蹄部皮质指数最大,利于提高耐磨性,强化保护功能。为应对寒冷环境,岩羊粗毛横向和纵向同时扩大 ...
