The oriental white stork (Ciconia boyciana) is a threatened species, and their numbers are still in decline due tohabitat loss and poaching. China is a breeding and main wintering area for this animal and in recent years someindividuals have been found breeding in wintering areas and at some stopover sites. These new breeding coloniesare an exciting sign, however, little is understood of the genetic structure of this species. Based on the analysis ofa 463-bp mitochondrial DNA (mtDNA) control region, we investigated the genetic structure and genetic diversity of66 wild oriental white storks from a Chinese population. We analyzed the sequences of 66 storks obtained in thisstudy and the data of 17 storks from a Japanese population. Thirty-seven different haplotypes were detected amongthe 83 samples. An analysis of molecular variance showed a significant population subdivision between the twopopulations (FST = 0.316, P < 0.05). However, the phylogenetic analysis revealed that the samples from the differentpopulations did not form separate clusters and that there were genetic exchanges between the two *** with the Japanese population, the Chinese population had a relatively higher genetic diversity with ahaplotype diversity (h ± SD) of 0.953 ± 0.013 and a nucleotide diversity (π ± SD) of 0.013 ± 0.007. The high haplotypediversity and low nucleotide diversity indicate that this population might be in a rapidly increasing period from asmall effective population. A neighbor-joining tree analysis indicated that genetic exchange had occurred betweenthe newly arisen southern breeding colony and the northern breeding colony wintering in the middle and lowerYangtze River floodplain. These results have important implications for the conservation of the oriental white storkpopulation in China.

作者： Xin HUANG Tao PAN Demin HAN Liang ZHANG yinxu hou Lei YU Heming ZHENG Baowei ZHANG School of Life Sciences Anhui University South China Institute of Endangered Animals Anhui Center for Desease Control and Prevention Anhui Bird Watching Society Jianghuai School Anhui University

During a biological survey in July 2011, a pit viper was collected from the Yaoluoping Nature Reserve in the Dabie Mountains, Anhui, China. The pit viper’s the total length measured 836 mm with a dorsal ground color of yellowbrown, decorated by 56 dark-brown transverse bands. The 4thsupralabial squama of the new species is separated from subocular by two squamae, and the tip of tail is orange; this combination of characters distinguish it from other species of the genus Protobothrops. Based on the body proportions, number of squamae, body color pattern, and comparing the data of its life history with those of other species of Protobothrops, we herein describe it as a new species, belonging to the genus of Protobothrops.

Animal Husbandry and Feed Science 2014年第4期6卷 185-187,208页

作者： Qiao Limin Guo Tong Qiao Fuqiang Yao Hua Xiao Xishan hou yinxu Fu Jingtao Ren Kang Beijing Vocational College of Agriculture Group of Science Technology and Industry Beijing University of Agriculture Institute of Animal Science and Veterinary Medicine Beijing University of Agriculture Beijing Animal Husbandry and Veterinary Station

The study was to investigate the effects of different thawing temperatures(5,15,40,75,90 ℃) and times(1- 120 s) on properties of post-thaw cow semen by detecting frozen-thawed semen motility,acrosome integrity and tail membrane integrity,further obtaining the optimal thawing method of straw frozen semen from dairy cow. The results showed that(1) Thawing of the straw frozen semen of dairy cow at 75 ℃ for 3 s yielded the highest semen motility,followed by 40 ℃for 20 s,and the least by low temperature 5 ℃ and room temperature 15 ℃ with a semen motility of 0. 3,moreover thawing at high temperature 90 ℃ was not suitable for large scale production due to the difficult control of the temperature;(2) The acrosome intact rate and plasma membrane integrity rate of semens thawed at90 ℃ were remarkably lower than that at 40 ℃ and 75 ℃ significantly(P 75 ℃ > 90 ℃. In practice,the thawing method of straw frozen semen of dairy cow should be selected according to the specific circumstance and inseminated immediately,with the recommended condition of thawing at 75 ℃ for 3 s. If the thawed semen could not be inseminated immediately,the thawing should be performed at 20 s for 40 ℃to maintain the motility for a longer term.

Effects of Transport,Storage Temperature and Time on Parthenogenetically Developmental Competence of Sheep Oocyte

引用

Animal Husbandry and Feed Science 2014年第3期6卷 138-140页

作者： Qiao Limin Qiao Fuqiang Guo Tong Yao Hua Zhang Jinghe Xiao Xishan hou yinxu Guan Weijun Department of Husbandry and Veterinary Beijing Vocational College of Agriculture Group of Science Technology and Industry Beijing University of Agriculture Institute of Animal Science and Veterinary Medicine Beijing University of Agriculture Institute of Animal Science( IAS) Chinese Academy of Agricultural Science( CAAS)

This study was to investigate the effects of transport, storage temperature and time on parthenogenetical developmental competence of sheep oocyte. The ovaries were collected and randomly immersed in physiological saline at （ 10 - 15 ） ℃, （20 - 25 ） ℃ and （30 - 35 ） ℃ and transported to the laboratory for culture. They were divided into three groups randomly in an optimized transport temperature, kept in physiological saline at4 ℃, （14 -18） ℃ and （25 -30） ℃ respectively; 15 - 17 h later, the ovaries were cutured for the maturation and parthenogenetic activation of oocytes. The results showed that the optimal transport temperature of ovaries was 20 -25 ℃, when the maturation rate and blastocysts rate reached 67.44% and 35.93% respectively. Incubating sheep ovaries at （ 14 - 18 ） ℃ for （15 -17） h did not reduce the maturation rate （61.81%） and blastocysts rate （29.03%） of oocyte significantly. However, incubating sheep ovaries at 4 ℃ or （25 -30） ℃ significantly reduced the maturation rate （41.90%, 18.40% ） and cleavage rate （9.09%, 13.04% ）, and the ovaries could not develop into blastocysts at these two temperature ranges. It can be concluded that the optimal transport temperature of the sheep ovaries is 20 - 25 ℃, and incubation at 14 - 18 ℃ overnight in vivo does not affect the developmental competence of oocytes.

Animal Husbandry and Feed Science 2015年第4期7卷 203-204,207页

作者： Qiao Limin Ma Jianmin Qiao Fuqiang Yao Hua Xiao Xishan hou yinxu Fu Jingtao Ren Kang Beijing Vocational College of Agriculture Technology Industry Group.BUA Animal Science and Technology College Beijing University of Agriculture Beijing Municipal Bureau of Agriculture

The aim was to discuss the optimal storage environment and proper insemination time after thawing of 0.25 mL straw frozen semen. Straw frozen semen was thawed at 40 ℃ for 20 s, and then stored at 0 -4 ℃, 14 - 16 ℃, 25 -27 ℃ for 2, 4, 6, 8 and 10 h, respectively. The sperm motility was detected. After thawing, semen was stored at 0 - 4 ℃ and 14 - 16 ℃ for 10 h. Their sperm motilities （0.434 ±0. 016 7 and 0.423 ±0.019 6） had no significant differences （P 〉 0.05） with initial thawing motility （0.441 ± 0.030）. Sperm motility reduced as the storage time prolonged at 25 -27 ℃. Sperm motility after 6 h had signifi- cant differences with that of initial thawing motility （P 〈 O. 05 ）, and sperm motilities after 8 and 10 h showed extremely significant differences （P 〈 0.01 ）. Thus, sperm motility after thawing was still very high after stored at 0 -4 ℃ and 14 - 16 ℃ within 10 h, which met the requirements for insemination. Under this temperature and time ranges, sperm could be carried over long distances, which had small effects on sperm quality and reached the expected insemination effects. However, under the temperature of 25 - 27 ℃, semen should be used for insemination within 6 h after thawing.

Environmental factors affect animal behavior in a variety of ways. Compared to animals in the wild, captive animals are kept in narrow enclosures, suffer higher densities and are more intensely affected by human activities. Therefore, behavioral elasticity is likely modified to some extent in captive animals, which may negatively affect the possibility of successful release of endangered species in the wild. In our study we investigated the behaviors of the Oriental White Stork (Ciconia boyciana) in a semi-natural enclosure from 15 October 2005 to 8 September 2006 in Hefei Wildlife Park, China. The behavioral data were collected by instantaneous and scan sampling methods, and we analyzed the relationships between environmental factors and their behaviors. The amounts of time spent on maintenance behavior (foraging and moving) were at similar levels for birds reproducing multibroods (Group 1), birds reproducing one brood (Group 2) and birds without reproduction (Group 3). On the other hand, the amount of time spent on elastic behavior (defensive, breeding and preening) for Group 3 was lower than that for Groups 1 and 2. The behavioral pattern of the storks exhibited marked seasonal changes, which may be a function of ambient temperature, human disturbanc, and the length of daylight, but not of wind intensity. Our results provide basic data for future conser- vation measures of this endangered species.
