“…LRTs were carried out by comparing twice the difference in ln likelihood scores of nested models against a χ 2 distribution with the degrees of freedom equal to the number of extra parameters estimated by the more complex model. The species tree was constructed based on the published mtDNA phylogenetic tree of R. ferrumequinum (Sun et al, 2013), and the inner relationships within each of the three mtDNA groups were respectively constructed using MrBayes 3.2.0 and nucleotide sequences of the ZBED1 CDS. The best-fit models selected for 1st, 2nd and 3rd codon sites within the Northeast group were TIM, HKY and HKY, respectively.…”

“…The greater horseshoe bat Rhinolophus ferrumequinum Schreber 1774, has a wide distribution in China and is found from southern China to northern China, and three divergent mtDNA evolutionary groups (Northeast, Central-East, Southwest) are identified (Sun et al, 2013). The Northeast group, which is distributed in Northeast China, hibernates strictly from December to April during winter, whereas the Southwest group, which is distributed in Southwest China, where the weather is warm and food is available even during winter, is active year-round (Aulagnier et al, 2008).…”

Mammalian hibernators experience physiological extremes, e.g. ischemia, muscle disuse and hypothermia, which are lethal to nonhibernators, implying the existence of underlying mechanisms that allow hibernators to withstand these physiological extremes. Increased cell proliferation is suggested to be such a strategy, but its molecular basis remains unknown. In this study, we characterized the expression pattern of ZBED1 (zinc finger, BED-type containing 1), a transcription factor that plays a crucial role in regulating cell proliferation, in five tissues of the greater horseshoe bat (Rhinolophus ferrumequinum) during pre-hibernation, deep hibernation and post-hibernation. Moreover, we investigated the ZBED1 genetic divergence from individuals with variable hibernation phenotypes that cover all three known mtDNA lineages of the species. Expression analyses showed that ZBED1 is overexpressed only in brain and skeletal muscle, not in the other three tissues, suggesting an increased cell proliferation in these two tissues during deep hibernation. Evolutionary analyses showed that ZBED1 sequences were clustered into two well-supported clades with each one dominated by hibernating and non-hibernating individuals, respectively. Positive selection analyses further showed some positively selected sites and a divergent selection pressure among hibernating and non-hibernating groups of R. ferrumequinum. Our results suggest that ZBED1 as a potential candidate gene that regulates cell proliferation for hibernators to face physiological extremes during hibernation.

Abstract:Bat is an important keystone member in the ecosystem, which is the only flying mammal. It plays a vital role in maintaining eco-balance through propagation of vital flora. Bat has a major role in pest management in the forest. Bats give major indication for biodiversity conservation through propagation and pest management. Bats are also the key informers of climate change and its impact on their habitat. Bat species and their activity are useful to assess habitat quality and they serve as biological indicators of the ecosystem conditions and degradation. Diversity of bat species is studied using various techniques including speech recognition, voice recognition, artificial neural networks etc. and to detect the presence of bats acoustically. In this paper, the various computer techniques used to study bats are surveyed.

“…For instance, light pollution from illumination of buildings could cause stunted growth of house-dwelling bats (Boldogh et al, 2007) and even non-tactile stimuli could arouse hibernating bats (Thomas, 1995). Populations of bats in various habitats also show geographic variation in phenotype, such as morphology and acoustic traits (Maharadatunkamsi et al, 2000;Sun et al, 2013). Thus, bats may present an opportunity to explore the evolutionary potential of epigenetic variance in environmental adaptation.…”

When facing the challenges of environmental change, such as habitat fragmentation, organisms have to adjust their phenotype to adapt to various environmental stresses. Recent studies show that epigenetic modifications could mediate environmentally induced phenotypic variation, and this epigenetic variance could be inherited by future generations, indicating that epigenetic processes have potential evolutionary effects. Bats living in diverse environments show geographic variations in phenotype, and the females usually have natal philopatry, presenting an opportunity to explore how environments shape epigenetic marks on the genome and the evolutionary potential of epigenetic variance in bat populations for adaptation. We have explored the natural epigenetic diversity and structure of female populations of the great roundleaf bat (Hipposideros armiger), the least horseshoe bat (Rhinolophus pusillus) and the eastern bent-winged bat (Miniopterus fuliginosus) using a methylation-sensitive amplified polymorphism technique. We have also estimated the effects of genetic variance and ecological variables on epigenetic diversification. All three bat species have a low level of genomic DNA methylation and extensive epigenetic diversity that exceeds the corresponding genetic variance. DNA sequence divergence, epigenetic drift and environmental variables contribute to the epigenetic diversities of each species. Environmentinduced epigenetic variation may be inherited as a result of both mitosis and meiosis, and their potential roles in evolution for bat populations are also discussed in this review. KEY WORDS: DNA methylation, Chiroptera, Mammals, Environmental adaptation IntroductionWhen facing challenges from environmental changes or stresses, organisms have to adapt to the changed environment by genetic mechanisms, physiological adaptability, phenotypic plasticity or moving to a new, more suitable area. The genetic changes may support abundant phenotypic variation in organisms for environmental adaptation, but they occur slowly and cannot keep pace with the rapidly changing environment (Bonduriansky et al., 2012). Recent studies have suggested that epigenetic modifications in eukaryotes could affect genetic expression and thus may mediate phenotypical variation in response to rapid and unpredictable environmental changes without genetic divergence (Dolinoy et al., 2007;Gao et al., 2010; Kucharski et al., 2008). These environmentally induced epigenetic patterns may even be stably inherited by future generations (Grant-Downton and Dickinson, 2006; Jablonka and Lamb, 1998;Richards, 2006), which provides an additional pathway for environmental adaptation and produces a challenge to the Modern Evolutionary Synthesis (Bossdorf et al., 2008; Jablonka and Lamb, 1995; Jablonka et al., 2005), in that the epigenetic process is another source of random variation in natural populations in addition to genetic variance (Massicotte et al., 2011;Schmitz et al., 2011).DNA methylation, one of the key epigenetic markers, is a covalen...
