Abstract This study investigates acoustic variation of human-audible sonic (below 20 kHz) and human-inaudible ultrasonic (above calls in a wild subterranean rodent, the Northern Mole Vole (Ellobius talpinus), under 3 call-eliciting tests conducted during captures for 1 day. The Contact-in-Tunnel Test modeled contacts 2 individuals digging earth burrow tunnel. Restraint restraint an animal by surrogate predator (human hand). Release-to-Burrow communication many family members returned to...
The generic status of Lasiopodomys and its division into subgenera (L. mandarinus, L. brandtii) Stenocranius gregalis, raddei) are not generally accepted because contradictions between the morphological molecular data. To obtain cytogenetic evidence for genus to test autosome sex chromosome translocation hypothesis complex origin in mandarinus proposed previously, we hybridized painting probes from field vole (Microtus agrestis, MAG) Arctic lemming (Dicrostonyx torquatus, DTO) onto...
Life under the earth surface is highly challenging and associated with a number of morphological, physiological behavioral modifications. Subterranean niche protects animals from predators, fluctuations in environmental parameters, but characterized by high levels carbon dioxide low oxygen implies energy requirements burrowing. Moreover, it lacks most sensory inputs available above ground. The current study describes results RNA-seq analysis four subterranean voles subfamily Arvicolinae:...
Based on the social structure of free-living mandarin voles (Lasiopodomys mandarinus), high paternal investment might be expected for this species. This prediction was tested under laboratory conditions. We observed 10 pairs rearing their first litter. All exhibited permanent nest cohabitation. Females never prevented males from entering natal nest. Males all patterns direct care young except nursing: huddling over, brooding with kyphosis, grooming, manipulating, and retrieving young. There...
This study evaluates signatures of selection in the evolution mitochondrial DNA voles, subfamily Arvicolinae, during colonization subterranean environments. The comparative sequence analysis protein-coding genes eight vole species (Prometheomys schaposchnikowi, three genus Ellobius: Ellobius talpinus, fuscocapillus and lutescens, two Terricola: Terricola subterraneus daghestanicus, Lasiopodomys mandarinus, Hyperacrius fertilis) their closest aboveground relatives was applied using...
The mandarin vole, Lasiopodomys mandarinus, is one of the most intriguing species among mammals with non-XX/XY sex chromosome system. It combines polymorphism in diploid numbers, variation morphology autosomes, heteromorphism X chromosomes, and several systems origin which remains unexplained. Here we elucidate determination system mandarinus vinogradovi using extensive karyotyping, crossbreeding experiments, molecular cytogenetic methods, single DNA sequencing. Among 205 karyotyped voles,...
Mole voles are the most specialized subterranean members of subfamily Arvicolinae. We assess basic reproductive parameters Zaisan mole vole (Ellobius tancrei Blasius, 1884) and compare our data with characteristics reported for other Ellobius species surface-dwelling voles. In respects, reproduction E. follows pattern that is typical Females undergo postpartum estrus, but rarely combine pregnancy lactation. The rate embryonic postembryonic growth (0.13 0.54 g/day, respectively) slightly...
This study provides the first evidence of ultrasonic vocalisations (USVs) in a truly subterranean rodent, northern mole vole Ellobius talpinus. Calls were recorded by attracting callers with bait to burrow entrances, where they mostly visible researchers. USVs from 14 different burrows southern Russia verified as belonging talpinus comparison two wild-captured young males and four adults captive colony. As attempt at exploring function USV diversity, we defined upward-intense USVs, maximum...
Abstract Background Ellobius talpinus is a subterranean rodent representing an attractive model in population ecology studies due to its highly special lifestyle and sociality. In such studies, mitochondrial DNA (mtDNA) widely used. However, if nuclear copies of mtDNA, aka NUMTs, are present, they may co-amplify with the target mtDNA fragment, generating misleading results. The aim this study was determine whether NUMTs present E. . Methods results PCR amplification putative CytB -D-loop...
Abstract Non-invasive age estimation is critically important for many field studies but often it represents a significant challenge. In rodents, upper incisors represent part of cranium which can be readily measured in an alive animal. We propose method based on the measurements both incisors’ width (IW) subterranean rodent, Ellobius tancrei . The IW 77 laboratory-born females and 81 males were fitted, separately sexes, by sigmoidal Gompertz growth functions to obtain asymptotic values....
Group-living and cooperative breeding in the mandarin vole Lasiopodomys mandarinus were proposed to be an adaptation (or preadaptation) fossorial mode of life (Smorkatcheva, 1999).This hypothesis involved indirect benefits that gain offspring by helping their mother tunnel construction among factors promoting breeding.Answer question which animals do provide most help?may allow us understand whether helpers derive direct or from action.In this study we compared contributions nest-residence,...
Abstract Most studies which deal with natural populations require a reliable and convenient way of age estimation. However, even rough aging live individuals is often real challenge. In this study, we develop radiographic method estimation in Ellobius talpinus , promising model species for population behavioral ecology. Using portable X-ray equipment, radiographed wild, non-sedated animals from the that had been subjected to extensive mark-recaptures 3 years. Two molar metrics strongly...
Subterranean rodents represent an interesting model system for molecular ecologists. Their lifestyle is associated with fragmented environments, limited dispersal ability, and low fecundity. These characteristics all are expected to increase inter- intrapopulation differentiation reduce intra-population genetic diversity, yet the published empirical data revealed lack of generality this pattern. This emphasizes importance accumulating more on individual species understand what factors shape...
