China has a history and reputation of substantial exploitation of wildlife, and the harvest and trade of wild birds are common throughout the country, both for exportation and local demand. This study documents the diversity and quantity of birds being traded in the city of Guiyang, Southwest China, and evaluates its potential conservation effects. Data were collected through direct observations and through informal conversations on weekends in a public market between March 2014 and February 2015. In total, 206 species belonging to 40 families and 13 orders were recorded, with the family Turdidae having the largest species diversity observed (28 species). The number of individuals on sale was greatly variable among different species. Ashy-throated parrotbills (Paradoxornis alphonsianus) were the most encountered birds, mainly driven by the practice of bird fighting, followed by Acridotheres cristatellus, Garrulax canornus, Zosterops japonicas, Zosterops palpebrosa, Zosterops erythropleurus, Rhyacornis fuliginosus, Emberiza elegans, Leiothrix lutea and Phoenicurus auroreus, which are all common and native to Guiyang. Our data indicated that at least 2000 individuals have been traded in one year for each of these species. We argue that the current bird trade raises a serious potential threat of over-exploitation of these species, especially due to bird fighting and hunting during the breeding season, as well as raising further potential threats of invasive species spread and disease transmission. Measures to control the trade are discussed here, and environmental education could be the most effective. This study highlights the significance of paying more attention to the domestic bird trade in the subtropical region. © 2017 Springer-Verlag Berlin Heidelberg

The giant panda (Ailuropoda melanoleuca) and golden takin (Budorcas taxicolor bedfordi) are large endangered species that coexist within the southern Qinling Mountains, China. Here, we determined the coexistence mechanisms for these sympatric species by investigating microhabitat selection from May to July and from September to November 2009 in a nature reserve. Our results suggested that each species has a distinct microhabitat selection pattern. We found that abiotic factors (elevation and slope) and biotic factors (bamboo cover, density and herb-cover proportion) are simultaneously responsible for microhabitat separation between giant pandas and golden takins during the summer and the winter. We inferred that pattern of microhabitat separation is influenced by diet, migration time, the annual phenological cycle of food resources, energy expenditure and metabolic requirements. Appropriate conservation strategies should not only focus on giant panda protection, but also be extended to encompass the protection of sympatric species. Our study has significant implications for biodiversity conservation across large tracts of China. © NwjZ, Oradea, Romania, 2017.

MicroRNAs (miRNAs) regulate many physiological processes through post-transcriptional control of gene expression and are a major part of the small noncoding RNAs (snRNA). As hibernators can survive at low body temperatures (Tb) for many months without suffering tissue damage, understanding the mechanisms that enable them to do so are of medical interest. Because the brain integrates peripheral physiology and white adipose tissue (WAT) is the primary energy source during hibernation, we hypothesized that both of these organs play a crucial role in hibernation, and thus, their activity would be relatively increased during hibernation. We carried out the first genomic analysis of small RNAs, specifically miRNAs, in the brain and WAT of a hibernating bat (Myotis ricketti) by comparing deeply torpid with euthermic individual bats using high-throughput sequencing (Solexa) and qPCR validation of expression levels. A total of 196 miRNAs (including 77 novel bat-specific miRNAs) were identified, and of these, 49 miRNAs showed significant differences in expression during hibernation, including 33 in the brain and 25 in WAT (P≤0.01 & |logFC|≥1). Stem-loop qPCR confirmed the miRNA expression patterns identified by Solexa sequencing. Moreover, 31 miRNAs showed tissue- or state-specific expression, and six miRNAs with counts >100 were specifically expressed in the brain. Putative target gene prediction combined with KEGG pathway and GO annotation showed that many essential processes of both organs are significantly correlated with differentially expressed miRNAs during bat hibernation. This is especially evident with down-regulated miRNAs, indicating that many physiological pathways are altered during hibernation. Thus, our novel findings of miRNAs and Interspersed Elements in a hibernating bat suggest that brain and WAT are active with respect to the miRNA expression activity during hibernation. © 2015 Yuan et al.

Manis javanica has been listed as a critically endangered species by IUCN due to over commercial harvesting (for food and medicine) and international trade. Identifying the species and sources of M. javanica in markets is important for resource conservation and trade controls. Mitochondrial DNA is a powerful molecular marker for species identification, phylogeography analysis, population genetics research and evolutionary studies. In this study, we sequenced and characterized the complete mitochondrial genome of M. javanica. The full length of the complete mitochondrial DNA was 16,576 bp. It contained 13 protein-coding genes, 22 tRNA genes and two rRNA genes. The tRNA genes fold into the expected cloverleaf secondary structures with normal base pairing, except the tRNASer(AGN) which lost the stem of DHC loop. This investigation provides complete mitochondrial genome of M. javanica which is an effective molecular tool for the genetic research and protection of this endangered species. © 2015, Springer Science+Business Media Dordrecht.

Cordyceps militaris is an important medicinal fungus. Commercialization of this fungus needs to improve the fruiting body production by molecular engineering. An improved Agrobacterium tumefaciens-mediated transformation (ATMT) method was used to select an insertional mutant (g38) which exhibited fast stromatal differentiation and increased yield. The Rhf1 gene encoding filamentation protein was destroyed by a single T-DNA and no Rhf1 transcription was detected in mutant g38. To verify the function of the Rhf1 gene, RNA interference plasmid and overexpression vector of the Rhf1 gene were constructed and transferred to the wild-type JM4 by ATMT. Fast stromatal differentiation and larger fruiting bodies were found in the RNAi-Rhf1 mutants (JM-iRhf1). In the overexpression mutants (JM-OERhf1), neither stromata nor fruiting bodies appeared. The rescued strain (38-OERhf1) showed similar growth characteristics as JM4. These results indicated that the Rhf1 gene was involved in the stromatal differentiation and the shape formation of fruiting bodies. © 2015, Society for Industrial Microbiology and Biotechnology.

Termite (Blattodea: Termitoidae) assemblages have important ecological functions and vary in structure between habitats, but have not been studied in lower subtropical forests. To examine whether differences in the richness and relative abundance of termite species and functional groups occur in lower subtropical regions, termite assemblages were sampled in Dinghushan Biosphere Reserve, China, among pine forest, pine and broad-leaved mixed forest (mixed forest), and monsoon evergreen broad-leaved forest (monsoon forest). The dominant functional group was wood-feeding termites (family Termitidae), and the mixed forest hosted the greatest richness and relative abundance. Soil-feeding termites were absent from the lower subtropical system, while humus-feeding termites were sporadically distributed in mixed forest and monsoon forest. The species richness and functional group abundance of termites in our site may be linked to the forest succession. Altitude, soil temperature, air temperature, surface air relative humidity, and litter depth were significant influences on species and functional group diversity. © 2015 The Authors 2015.

Each animal population has its own acoustic signature which facilitates identification, communication and reproduction. The sonar signals of bats can convey social information, such as species identity and contextual information. The goal of this study was to determine whether bats adjust their echolocation call structures to mutually recognize and communicate when they encounter the bats from different colonies. We used the intermediate leafnosed bats (Hipposideros larvatus) as a case study to investigate the variations of echolocation calls when bats from one colony were introduced singly into the home cage of a new colony or two bats from different colonies were cohabitated together for one month. Our experiments showed that the single bat individual altered its peak frequency of echolocation calls to approach the call of new colony members and two bats from different colonies adjusted their call frequencies toward each other to a similar frequency after being chronically cohabitated. These results indicate that the 'compromise' in echolocation calls might be used to ensure effective mutual communication among bats. © 2016 Chen et al.

Epidemiological studies and meta-analyses report a strong relationship between chronic pain and abnormalities in glucose metabolism, but the exact relationship between chronic pain and insulin resistance in type 2 diabetes (T2D) remains unknown. Using a model of neuropathic thermal and tactile hypersensitivity induced by chronic constriction injury (CCI) of the sciatic nerve in Zucker Diabetic Fatty (ZDF) and Zucker Lean (ZL) littermates, we compared the recovery period of hypersensitivity and the progression of T2D and studied the possible involvement of insulin receptors (IRs) in the comorbidity of these 2 conditions. We found that the nociceptive thresholds to thermal and mechanical stimulation in naive ZDF rats were lower than in ZL littermates at 6 weeks of age. Although ZDF and ZL rats developed thermal and tactile hypersensitivity after CCI, it took a longer time nociceptive sensitivity to be restored in ZDF rats. Nerve injury accelerated the progression of T2D in ZDF rats, shown by an earlier onset of hyperglycemia, more severe hyperinsulinemia, and a higher concentration of glycosylated hemoglobin Alc 6 weeks after CCI, compared with those in naive ZDF and ZL rats. IR-immunoreactive cells were located across the central nervous system and skeletal muscles. In the central nervous system, IR coexpressed with a neuronal marker (neuronal nuclei) but not a glial marker (glial fibrillary acidic protein). There was a low level of IR expression in skeletal muscles of naive ZDF rats. In contrast, CCI reduced the IR expression in skeletal muscles as well as the ipsilateral spinal cord, primarily in the dorsal horn. In conclusion, our data suggest that the relationship between insulin resistance and chronic pain in ZDF rats is bidirectional and an impaired IR signaling system might be implicated in this reciprocal relationship. Perspective Nerve injuries in genetically susceptible individuals might accelerate the development of insulin resistance as in T2D. A downregulated expression of IRs in the skeletal muscle innervated by the injured nerve is one of the underlying mechanisms. © 2016 American Pain Society.

Turtles are an excellent group for understanding the theory of sexual selection, sexual dimorphism and the evolution of courtship behaviour. Asia has a rich diversity of turtle species, but quantitative analysis of courtship behaviour has only been conducted on a single species. This study quantitatively analysed courtship and mating behaviours of captive Platysternon megacephalum to serve as a basis for future comparisons with other freshwater turtles. A total of 259 courtship behaviour sequences stemming from 66 pairings between 12 males and 24 females were analysed. Seven (approaching, sniffing, chasing, resting, mounting, subduing female, copulating) and three mutually exclusive motor patterns (fleeing, mating resistance, mating acceptance) were performed by males and females, respectively. The temporal sequences of courtship and mating behaviours were analysed using Chi-square tests and Kappa analyses, from which a flow diagram was constructed. Male courtship display patterns involved tactile, visual and olfactory cues for conspecific and sexual recognition. In response, females may have emitted olfactory cues regarding their sex and reproductive status. Male P. megacephalum exhibited biting, but no head movement or foreclaw display in courtship, which differs from other freshwater turtles. This study provides the first record of male biting during courtship behaviour in an Asian turtle species. Recommendations for captive breeding of the endangered species P. megacephalum are presented. © 2016, British Herpetological Society. All rights reserved.
