The Spatial Niche and Influencing Factors of Desert Rodents.

Resource partitioning may allow species coexistence. Sand dunes in the typical steppe of Alxa Desert Inner Mongolia, China, consisting of desert, shrub, and grass habitats, provide an appropriate system for studies of spatial niche partitioning among small mammals. In this study, the spatial niche characteristics of four rodents, , , and , and their responses to environmental changes in the Alxa Desert were studied from 2017 to 2021.

The effect of grazing on winter survival of midday gerbil () of different genders.

The objective of this study was to investigate the effects of grazing on midday gerbil () population characteristics and survival of animals of different genders. The experiment used a randomized complete block design and was conducted in Alxa Left Banner, Inner Mongolia, China, in 2002 (The agricultural reclamation plots set up in 1994). From April 2006 to October 2010, midday gerbils were live-trapped in 3 light grazing plots, 3 overgrazed plots, and 3 grazing exclusion plots.

The burrow behavior and influenced factors of a prairie subterranean zokor ().

The Transbaikal zokor () is a dominant rodent distributed in the meadow steppe of Inner Mongolia in northern China. Due to long history of evolution in subterranean environment, the zokor has an adaptive behavior: sealing burrow entrances. When a burrow is damaged, exposed entrances appear, and within a relatively short time, the zokor would be active in sealing the entrances to reduce risks to its survival.

Environmental metabolomics reveal geographic variation in aerobic metabolism and metabolic substrates in Mongolian gerbils (Meriones unguiculatus).

Mongolian gerbils (Meriones unguiculatus) have a large-scale distribution in northern China. Geographic physiological variations which related to energy and water metabolism are critical to animals' local adaptation and distribution. However, the underlying biochemical mechanism of such variation and its role in adaptation remains largely unknown.

[Application of reflection infrared sensor to intelligent water-saving system].

Utilizing reflection type infrared sensor and small electronic devices (monostable multivibrator), the authors have developed the intelligent water-saving control system. This system can discern whether someone enters the lavatory, produce the signal of washing according to the cirumstances, drives the electromagnetic valve to open, and pour water into the floater type cistern. After filling two cisterns of water enough for cleaning, it'll cut off the power in the electromagnetic valve automatically.
