“…In our study, the SVL mean of females did not significantly differ from that of males, although the latter were bigger on average. Similar to our results, no statistically significant difference between the sexes was reported in the studies of Eremias multiocellata (Li et al, 2006), Phymaturus patagonicus (Piantoni et al, 2006), Lacerta agilis (Guarino et al, 2010), and Eremias argus (Kim et al, 2010). In contrast to our study, the SVL mean of females was significantly larger than that of males in Sceleporus undulatus (Haenel and John-Alder, 2002) and Lacerta vivipara (Liu et al, 2008).…”

“…In our study, we found the maximum observed longevity to be 7 years for males and 5 years for females. For Eremias argus females and males, it has been reported as 11 years and 8 years, respectively (Kim et al, 2010). In our study, the SVL mean of females did not significantly differ from that of males, although the latter were bigger on average.…”

“…Some of these studies concern mating behavior (Kim et al, 2012a), sexual size dimorphism (SSD) (Li et al, 2006), reproduction Yue et al, 2012), phylogeny (Guo et al, 2011), home range (Kim et al, 2012b), and genetics . The only demographic study about this genus is on the species Eremias argus (Kim et al, 2010). Although the morphological features of Eremias strauchi strauchi (Ahmadzadeh et al, 2009) have been studied, there are no data available about the age structure of this subspecies.…”

“…This method has been used to determine ages of many amphibian and reptile species (Yılmaz et al, 2005;Üzüm, 2009;Kim et al, 2010;Tomašević et al, 2010). Although it has been stated that age determination by skeletochronology in lizards deviates by 1 or 2 years from ages calculated via the mark-recapture method (Smirina and Tsellarius, 1996), skeletochronology has been preferred to other methods because of its time-saving feature.…”

Habitat fragmentation caused by anthropogenic activities alters the distribution, abundance and diversity of wildlife species worldwide. As one example, Siberian marmots have experienced a >75% decline across Mongolia since the 1990s due to human harvests. Burrowing mammals are keystone; ecosystem engineers in many communities because burrowing can directly and indirectly alter the availability of resources, have effects at multiple spatial and temporal scales, and have a significant role in community organization. The deep and complex burrow systems of marmots provide underground shelters with stable microclimates that other vertebrate and invertebrate animals exploit. Our general hypothesis was that marmot colonies positively influence racerunner occupancy probability because burrows offer shelter from environmental conditions, refuges for predation, and a high diversity and number of insects and other prey items. Using occupancy modeling, we showed that the presence of a Siberian marmot colony influenced racerunner occupancy. Marmot active colony + inactive colony-ψ (AMC+IMC), p (temp+temp 2 ) were the best approximating model. Racerunner detection was highest at approximately 24.3°C. For the aspect and elevation model, foothills had an important influence on lizard occupancy. Our results showed that marmot burrows greatly influence Mongolian racerunner occurrence and suggest that habitat modification by rodent ecosystem engineers exert ecological influence on biodiversity.

Age‐related reproduction of female Mongolian racerunners (Eremias argus; Lacertidae): Evidence of reproductive senescence

The reproductive maturation hypothesis, the terminal investment hypothesis, and the senescence hypothesis are the most extensively evaluated hypotheses proposed to explain age‐related patterns of reproduction in iteroparous organisms. Here, we evaluated these hypotheses for the Mongolian racerunner (Eremias argus), a short‐lived lacertid lizard, by comparing reproductive traits between females that completed reproductive cycles under the same laboratory conditions in two consecutive years (2008 and 2009). Reproductive females gained linear size (snout‐vent length) not only as they got 1 year older but also during the breeding season. Larger females generally laid eggs earlier and invested more in reproduction than did smaller ones. Females switched from laying smaller eggs in the first clutch to larger eggs in the subsequent clutches but kept clutch size and postpartum body mass constant between successive clutches in a breeding season and between years. Females that laid more clutches or eggs in 2008 did not lay fewer clutches or eggs in 2009. Of the traits examined, only clutch frequency, annual fecundity, and annual reproductive output were susceptible to ageing. Specifically, the clutch frequency was reduced by 1.1 clutches, annual fecundity by 3.1 eggs and annual reproductive output by 1.0 g in 2009 compared with 2008. Our results suggest that the reproductive maturation hypothesis better explains patterns of reproduction in young or prime‐aged females of E. argus, whereas the senescence hypothesis better explains reproductive patterns in old females. The terminal investment hypothesis does not apply to any trait examined because no trait value was maximized in old females.
