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.

Would future climate warming cause zoonotic diseases to spread over long distances?

is a major rodent found in arid environments and desert areas. They feed on plant seeds, young branches and some small insects, and have hibernating habits. Peak numbers impact the construction of the plant community in the environment, but also have a human impact as these rodents carry a variety of parasitic fleas capable of spreading serious diseases to humans.

Controlling Effects of Nanocomposite Sterilant ND-1 on the Growth of Wild Populations of Midday Gerbil ().

Grassland is not only an important part of the terrestrial ecosystem with multiple ecological functions, but also an important base for Chinese herdsmen to produce and live. However, the occurrence and spread of rodent infestation reduces the biodiversity and productivity of grassland ecosystems. It also severely threatens human life, health, and biosecurity through disease transmission.

Influence of biotic and abiotic factors on flea species population dynamics on .

Brandt's Vole ( is one of the most abundant rodent species in the grasslands of Inner Mongolia, China, and one of the main carriers of , the plague bacterium. There have been several instances of plague transmission among , and all of their dominant flea species are known carriers of plague. Little work has been done to understand the regulation of flea abundance on by biotic and abiotic factors.

Synergistic effects of EP-1 and ivermectin mixture (iEP-1) to control rodents and their ectoparasites.

Background: Ectoparasites of rodents play significant roles in disease transmission to humans. Conventional poisoning potentially reduces the population densities of rodents, however, they may increase the ectoparasite loads on the surviving hosts. EP-1 has been shown to have anti-fertility effects on many rodent species, while ivermectin is effective in controlling ectoparasites.

Size segregation of disk particle in two-dimensional chute.

Size segregation will lead to stratification of a particle system. At present, people have not fully understood the segregation mechanism. In this work, we have studied the size segregation behavior of two-component disk particles in chute flows.

Activity strategy and pattern of the Siberian jerboa () in the Alxa desert region, China.

Rodents exhibit seasonal changes in their activity patterns as an essential survival strategy. We studied the activity patterns and strategies of the Siberian jerboa () in the Alxa desert region to better understand the habitats and behavioural ecology of xeric rodents. We conducted an experiment using three plots to monitor the duration, time, and frequency of the active period of the Siberian jerboa using infrared cameras in the Alxa field workstation, Inner Mongolia, China in 2017.

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.

Complete mitochondrial genome of Myospalax aspalax (Rodentia, Spalacidae).

False zokor (Myospalax aspalax) is one of the subterranean rodents distributed in East Asia. Molecular data and demography of M. aspalax are unknown, and the population management is difficult, because it is specialized for underground life.

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.

Effects of levonorgestrel-quinestrol (EP-1) treatment on Mongolian gerbil wild populations: a case study.

Rodent pest population outbreaks occur frequently in grassland ecosystems in northern China. The Mongolian gerbil (Meriones unguiculatus) is a dominant pest rodent which is distributed across the semi-desert grasslands of Inner Mongolia, China. In 2009, we studied the contraceptive effect of levonorgestrel-quinestrol (EP-1), concentration 50 ppm, on a wild Mongolian gerbil population.

[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.
