In order to figure out the status of biodiversity restoration and distribution characteristics, we applied ArcGIS 9.3 software system to establish a GIS database for the ecological distribution of 66 species of birds under state key protection belonging to nine orders, and analyzed the distribution trend at different periods. The results showed that the overall distribution of the rare birds was concentrated around original forests with high quality vegetation, reservoirs and big rivers in mountainous areas, city parks and woodlands with less human disturbance in plain areas; however, there was no distribution in farmland areas. Comparing the ecological distribution sites of birds under State Key Protection Class I before and after the 1990s, it was found that the distribution was sparse, but three new species appeared after the 1990s, namely Chinese merganser (Mergus squamatus), brown eared pheasant (Crossoptilon mantchuricum) and relict gull (Larus relictus). Furthermore, the distribution sites of previous threeorders expanded. The birds under State Key Protection Class II also had an expansion trend in distribution with two new species of the hazel grouse (Bonasa bonasia) and demoiselle crane (Grus virgo); however, the black tern (Chlidonias niger) and black-faced spoonbill (Platalea minor) could not be found. The above results revealed that there is a positive recover for the overall distribution of the rare birds with the restoration of forests and wetlands in Beijing. The fact that some species disappeared recently indicated that protection of the habitat of wildlife is still a long-term process of constructing ecological environment. The GIS database lays the groundwork for building the management platform of rare wild animal distributions in Beijing, and possesses the important applicable value for the measures of protecting the wild animal populations and their habitats at landscape level. ©, 2015, Beijing Forestry University.

Asian elephants in Chongqing zoo were repeatedly affected by fungal skin disease recent years. This study sought to establish New Zealand rabbit models infected with Microsporum canis which was pathogens of fungal skin disease developed in Asian elephants in Chongqing zoo. Bacterial colonies were incubated in Sabouraud dextrose agar at 28 ° C for 14 days and then prepared into bacterial suspension and inoculated on the dorsal skin of the rabbits. After 10 days inoculation, the affected skin of rabbits developed advent clinical symptoms such as scab and desquamation that were extremely similar to those of fungal skin disease in Asian elephants. The skin tissue at a size of 1 × 1 cm was collected. The paraffin section was prepared and stained for argentaffin. The pathological section showed that brown orange Microsporum canis was visible in skin tissue after argentaffin staining. The results showed that pathological New Zealand rabbit model for infection with pathogens of fungal skin disease developed in Asian elephants in Chongqing zoo was successfully established. © Medwell Journals, 2014.

In order to investigate the mitochondrial genome of Panthera tigris amoyensis, two South China tigers (P25 and P27) were analyzed following 15 cymt-specific primer sets. The entire mtDNA sequence was found to be 16,957 bp and 17,001 bp long for P25 and P27 respectively, and this difference in length between P25 and P27 occurred in the number of tandem repeats in the RS-3 segment of the control region. The structural characteristics of complete P. t. amoyensis mitochondrial genomes were also highly similar to those of P. uncia. Additionally, the rate of point mutation was only 0.3% and a total of 59 variable sites between P25 and P27 were found. Out of the 59 variable sites, 6 were located in 6 different tRNA genes, 6 in the 2 rRNA genes, 7 in non-coding regions (one located between tRNA-Asn and tRNA-Tyr and six in the D-loop), and 40 in 10 protein-coding genes. COI held the largest amount of variable sites (9 sites) and Cytb contained the highest variable rate (0.7%) in the complete sequences. Moreover, out of the 40 variable sites located in 10 protein-coding genes, 12 sites were nonsynonymous. © 2010 Springer Science+Business Media B.V. Source

This study aimed to investigate the safety and efficacy of Chinese medicine SH mixture on respiratory tract inflammation induced by herpesvirus. The clinical symptoms, mortality and incidence were observed to evaluate the preventive and therapeutic effects of SH mixture on infectious laryngotracheitis (ILT) in peacocks. Administration of SH mixture noticeably improved the clinical symptoms and decreased the mortality associated with ILT in peacocks. SH mixture also had a significant preventive effect on ILT. The results suggest that SH mixture has preventative and therapeutic effects on respiratory inflammation caused by herpesvirus. Improvement of immune and hematopoietic functions is possibly involved in its protective mechanism. Source
