Geographical patterns based on faunal types of breeding birds and mammals in China

Abstract

We collected available chorological data of birds and mammals in China and assigned faunal types. The 19 subregions of the zoogeographical regions of China were used as operative geographical units. Matrices of the geographical units using the species number of each faunal type were then constructed. Based on the matrices we clustered the geographical units using a hierarchical cluster analysis The results of the faunal divisions according to the cluster analysis were illustrated in a geographic information system (GIS). When 19 geographical units were clustered into two clusters, the boundary of the two clusters corresponded to that of the Palearctic and Indomalayan (Oriental) realms in the recent division of Chinese fauna. When the geographical units were clustered into eight clusters, the sub-region Southern Yunnan Hilly became an idiographic cluster. As a result, Southern Yunnan hilly should be regarded as a region rather than a sub-region at the same level as Southwest region, Central China region and South China region. The differences in the distribution patterns of birds and mammals among the units in the Indomalayan (Oriental) realm were more complicated than those in Palearctic realm. A few differences of the cluster analysis results based on the faunal types were found between the bird and mammal species. These differences might result from the different ecological and geographical distribution patterns of these two animal categories.

Distribution and characteristics of Beilong virus among wild rodents and shrews in China

“…Both of 2 tested species of Mustelidae family were negative for BeiV. The currently surveyed 11 provinces were grouped into 6 zoogeographic regions which are defined by climatic and ecological characteristics (Xing et al, 2008), including Northeastern China (Liaoning, Jilin and Heilongjiang), Inner Mongolia-Xinjiang region, Northern China (Beijing, Henan and Shandong), Southern China (Guangdong), Central China (Zhejiang), and Southwest China (Yunnan) (Fig. 3b).…”

Genetic Diversity and Expanded Host Range of J Paramyxovirus Detected in Wild Small Mammals in China

“…A total of 3070 wild small mammals that belonged to 66 species in six families were trapped, including 2518 from 29 species of the Muridae family, 239 from 15 species of the Cricetidae family, 148 from 12 species of the Soricidae family, 100 from 6 species of Sciuridae family, 47 from 2 species of Spalacidae family, and 18 from 2 species of the Dipodidae family ( Figure 1 , Table S2 ). The 11 surveyed locations were grouped into six eco-climate regions [ 19 ]. Eco-climate regions were used for the geographic description.…”

Distribution patterns and drivers of nonendemic and endemic glires species in China

“…Vegetation is also diverse, covering a wide range of zones, including rainforest, steppes, and desert. Referring to the previous studies (Xing, 2008; Zhou, 2000), we divided the Chinese territory into grid cell operating units of 80 × 80 km 2 to eliminate the influence of area on species distribution patterns. Incomplete grid cells (<75% of the complete cell) present in the study area in the coastline and boundary areas were removed to prevent them from affecting the subsequent statistical analysis.…”

“…Thus, multiple modeling approaches are best suited for quantifying the contribution of various hypotheses to spatial richness distribution patterns. Moreover, there are studies that explained the distribution of glires in China (Xing, 2008;Zhou, 2000), and the mechanism that determines richness patterns were initially discussed. Chi et al (2020Chi et al ( , 2021 studied the distribution pattern of terrestrial mammal abundance in China and its relationship with environmental factors.…”
