“…This observation proves that hybridization between these species was not the result of error in species recognition by one of the females, which could be receptive to co-specific individuals. This phenomenon probably occurs due www.nature.com/scientificreports www.nature.com/scientificreports/ to the social organization of these individuals, where dominant males have access to several females 44,45 with large home range areas 46 and in this case do not distinguish females from the same or different species.…”

Jorge c. pereira 5 , edivaldo Herculano corrêa de oliveira 6,7 , Malcolm A. ferguson-Smith 5 & thales Renato ochotorena de freitas 1,2,3 Reproductive compatibility usually decreases according to increasing genetic difference and the time of divergence between species. However, the amount of modification required to influence hybridization may vary in different species. Thus, it is extremely important to conduct studies that seek to understand what and how variables influence the reproductive isolation of species. We have explored a system involving two species of subterranean rodents that present morphological, karyotypic, and evolutionary history differences and are capable of generating hybrids. To gain insight into the karyotype organization of genus Ctenomys, we examined the chromosome evolution by classical and molecular cytogenetics of both parental species and hybrids. Furthermore, we have used different approaches to analyze the differences between the parental species and the hybrids, and determined the origin of the hybrids. The results of our work demonstrate unequivocally that some species that present extensive differences in chromosome organization, phenotype, evolutionary history, sperm morphology and genetic, which are usually associated with reproductive isolation, can generate natural hybrids. the results also demonstrate that females of both species are able to generate hybrids with males of the other species. In addition, the chromosome-specific probes prepared from Ctenomys flamarioni provide an invaluable tool for comparative cytogenetics in closely related species.

“…In 2016, radio fixes were taken in 24-h sessions for 10 days each month (the 15th to 25th of each month). To ensure the independence of data collection, there was a 2-h time interval between fixes [19]. In 2017, radio-tracking began 36-48 h after animal release.…”

“…For those small mammals inhabiting the underground environment, live trapping and radio-tracking become a valid tool to collect data systematically on their characteristics of movement and space use. At present, a few species of Bathyergus and Ctenomys, and Spalax studies on home range size have been carried out by radio-tracking [15][16][17][18][19]. Surprisingly, there are few studies on the long-term space utilization of subterranean rodents.…”

BackgroundSubterranean rodents, as ecosystem engineers, excavate and inhabit burrow systems. Their underground space-use mobility is poorly recorded. There is conflicting evidence regarding that burrow system of subterranean rodents, once established, are relatively stable because of high-energy costs of digging. For monitoring data at different stages of a year’s life cycle. We predict that mating and habitat characteristics might influence home-range size and locomotion.MethodsThe present study implemented successive radio-tracking in order to quantify the locomotion and overlap of the plateau zokor (Myospalax baileyi) home-range throughout the year. Home-ranges were calculated according to the 100% minimum convex polygon (MCP) methods. We also examined the relationships of home-range sizes with body mass, vegetation biomass, and soil compaction, respectively.ResultsWe found that sizes of home-ranges varied monthly for both male and female, except for the long winter (from November to March of the following year) challenging to excavate with activity ranges of all individuals concentrated on their own nests. During the mating season, the average size of males’ home-ranges is 3.4 times larger than females’ home-ranges. Males likely expanded the burrows to overlap with multiple females and to enhance their chances of mating. However, there was no overlap between estrus females or males, perhaps by reducing encounters and unnecessary fights. Home-ranges between males and females showed similar in size after courtship ends one month, and interestingly, single zokor’s home-range overlapped with the home-ranges of several neighbors. Most individuals remained territorial and excluded intraspecific from their home-ranges. Besides, the position of the females was stable throughout the year, while half of the males shifted nests and established completely new home-ranges in the non-breeding season, mainly in October. ConclusionsWe conclude that space use of M. baileyi is flexible in response to meet physical contact and food resource. Regarding locomotion of home-range, subterranean plateau zokors to affirm that their home-ranges are dynamics and males shift in space with one breeding cycle.

“…If the size of the home range of an animal is too large, it will be detrimental to the domain's occupant because the cost of defending their territory increases dramatically as the home range expands (Hinsch and Komdeur, 2017). The food resource and soil characteristics directly influence the size of the home range and the dynamics of the burrow systems of subterranean rodents in different types of habitat (Fisher and Owens, 2012;Lovari et al, 2013;Lövy et al, 2015;Kubiak et al, 2017). Larger animals don't 'require' more mates.…”

As ecosystem engineers, subterranean rodents excavate and inhabit burrow systems. However, the changes in their use of underground space are poorly recorded. There is conflicting evidence about whether the burrow systems of subterranean rodents, once established, are relatively stable as a result of the high energy costs of digging. We monitored the size of the home ranges of the plateau zokor (Myospalax baileyi) during different stages of its life cycle to show whether mating behavior and the characteristics of its habitat influence the size and location of its home range. We used radio-tracking to quantify the changes in, and overlap of, the home range of M. baileyi during a one-year period. The average size of the home ranges of male zokors was 6.5 times larger than that of female zokors during the mating season. The males expanded their burrows to overlap with multiple females to increase their chances of mating. However, there was no overlap between estrus females or males, perhaps to reduce the number of encounters and unnecessary fights. The home ranges of male and female zokors were similar in size after courtship and the home ranges of single zokors overlapped with those of several neighbors. Most individuals remained territorial and excluded intraspecific interactions from their home ranges. The location of female zokors was stable throughout the year, but half of the males changed the location of their nests and established completely new home ranges in the non-breeding season, mainly in October. The use of space by M. baileyi is flexible in response to a need for physical contact during the mating season and food resources. The home ranges of subterranean plateau zokors are dynamic and the home ranges of male zokors can change within one breeding cycle.
