Short Communication: Proportion faunal assemblage of rodents in geoecological districts of Mordovia, Russia

Abstract

Abstract. Andrechev A. 2020. Short Communication: Proportion faunal assemblage of rodents in geoecological districts of Mordovia, Russia. Biodiversitas 21: 3961-3968. In one natural area, animals may have different distribution. In some areas they inhabit, and in other areas, they do not inhabit. Scientists have been working on this issue for a long time. In this study reports that the species composition and distribution of species varies depending on geoecological districts. Twenty-eight rodent species have been recorded in the territory of Mordovia. The largest number of species in the region belongs to those living in coniferous and broad-leaved forests (42.9%). In the second place in terms of representation are species widely distributed in several natural areas (28.5%). They are slightly inferior to the types of steppe fauna (25%). The taiga type of fauna is represented by only 3.6% of the total number of registered species. For each geoecological district, the features of the rodent fauna are given and rare species are identified. The forest-steppe region of Mordovia is compared in rodent fauna with other regions of Russia with different typical faunal assemblages.

Short Communication: Proportion faunal assemblages of carnivorous mammals in geoecological districts of Mordovia, Russia

“…However, a notable difference between the carnivorous fauna of Karelia is a high proportion of taiga species compared with Mordovia. A similar situation was observed with the fauna of rodents (Andreychev 2020b).…”

“…In Mordovia, the proportion of carnivorous species of the total number of mammal species is 20%. Carnivorous is somewhat inferior to rodents (37%) (Andreychev 2020b;. Compared to West Java, Indonesia, Thailand, Mexico, the proportion of carnivorous species from other mammals is higher (Briceño-Méndez et al 2017;Husodo et al 2019;Sukmasuang et al 2020;Clements et al 2021).…”

Density and distribution of the greater mole rat (Spalax microphthalmus) on the northern border of the area in a region of European Russia

“…We compared the current range boundaries of the mole rat with data on its distribution in Mordovia in the past (Astradamov et al, 1976;Andreychev et al, 2010;Andreychev, 2020). It should be noted that it significantly expanded the areas of their habitat (Fig.…”

Commensals of underground mammals: European mole (Talpa europaea, Eulipotyphla, Talpidae) and the greater mole-rat (Spalax microphthalmus, Rodentia, Spalacidae)

“…In Mordovia, the European mole is distributed unevenly since the southern border of the range is not far away, namely, in the Penza region south of the city of Penza. The greater mole-rat is a rare species for the fauna of the Republic of Mordovia and is recorded as a local population on the northern border of the range (Andreychev 2019(Andreychev , 2020.…”
