Copulatory pattern and behavior in a semi-captive population of Eld＇s deer

Current Zoology 2011年第3期57卷 284-292页

作者： zhigao zeng yan-ling song qiong zhang Institute of Zoology Chinese Academy of Sciences Beijing 100101 China

Male copulatory patterns, female multiple copulation and male post-copulatory guarding were studied in Eld＇s deer Cervus eldi in Datian National Nature Reserve, China. Mating behavior in 18 females and 11 males from a group of 61 semi-captive Eld＇s deer were observed. The majority （55.8%） of copulations occurred between 15：00-19：00 h. The ejaculatory mount was preceded by an average of 5.1 prior mounts. Successful copulation consisted of a single thrust with ejaculation during one intromission, with no lock. This copulatory pattern is classified as pattern No. 15 （no lock, no intravaginal thrusting, single intromission, and multiple ejaculation） and No. 16 （no lock, no intravaginal thrusting, single intromission, and single ejaculation） under Dewsbury＇s scheme （1972） and as No. 16 （no lock, no thrusting, single and brief intromission） under Dixson＇s classification （1998）. Copulation frequency was 1.5 ± 0.9 times for males/females with the same female/male per day. The duration of the final mount, which included ejaculation, was brief （3.4±1.3 s）, and ejaculation usually terminated copulation. Eleven females copulated more than once in this study： three of them copulated with several males （multi-male copulations） and the remainder copulated with a single male （repeated copulations）. Our results indicate that some female Eld＇s deer may seek multiple copulations to be a strategy to improve the genetic quality of their offspring or to avoid harassment. Post-copulatory guarding of females by males followed all copulations, with dominant males guarding for significantly longer than subordinate males. Dominant males appear to be more effective at post-copulatory guarding than subordinate males. Subordinate males engaged in a quicker pre-copulatory phase to improve their chances of finishing copulation before being forced to accede to dominant males [Current Zoology 57 （3）： 284-292, 2011].

Rut-induced changes in the activity budgets of male tropical ungulates： Eld＇s deer on Hainan Island

Current Zoology 2012年第4期58卷 536-540页

作者： Jianhua DING Zhitao LIU yanling song zhigao zeng qiong zhang Benjamin D.BRAVERY Anhui Key Laboratory of Resource and Plant Biology School of Life SciencesHuaibei Normal UniversityHuaibei 235000ER.China Key Laboratory of Animal Ecology and Conservation Biology Institute of ZoologyChinese Academy of SciencesBeijing 100101China School of Life Sciences Harbin Normal UniversityHarbin 150025China

Aspects of time budgets, activity patterns and rut-related changes in behavior are well documented in temperate un-gulates; however, the application of this understanding to tropical and sub-tropical ungulate species has attracted less attention and remains an area that may re-shape our knowledge of ungulate behavior. Eld＇s deer Cervus eldi hainanus has a tropical and sub-tropical distribution on Hainan Island, China, and males have an extended rut exceeding five months during which they do not maintain harems or defend resources. We studied males from the only remaining population on Hainan Island, and describe rut-related changes in behavior by collecting data on time budgets and activity patterns. We show that male Eld＇s deer do not fol- low a strict crepuscular activity pattern, do not spend the majority of their time foraging and do not increase foraging nor display rut-induced hypophagia during rut, in obvious contrast to temperate ungulates. These results are discussed in light of current hy- potheses explaining the proximate mechanisms governing feeding time in ungulates, while appreciating the need for further re-search .

坡鹿是世界濒危物种,三个亚种分布在东南亚大陆,仅海南坡鹿种群分布在中国海南岛。2003年,国际社会的专家和学者提出了将海南坡鹿引入泰国亚种原分布区,重建已经绝灭野生种群的建议。在此种情况下,明确海南坡鹿的起源、与其它亚种间的系统发生关系、以及遗传多样性水平对有效保护坡鹿具有重要意义。本研究以线粒体DNAD-loop区490bp基因片段为分子标记,比较分析了海南坡鹿、泰国亚种和缅甸亚种共35个样本的序列差异。我们所测的样本中,总共发现4种单倍型。所有21个海南坡鹿样品共享1种单倍型。利用最大似然法(ML)、最大简约法(MP)、邻接法(NJ)和贝叶斯法(Bayesian)构建的系统进化树表明海南坡鹿种群与泰国亚种的关系较近。但是,二者也发生一定程度的遗传分化。海南坡鹿与泰国亚种的遗传距离均值为0.026。我们推测海南坡鹿可能是在更新世冰期(69万年前)通过陆桥由东南亚大陆迁入中国海南岛。我们的结论说明海南坡鹿的遗传多样性很低,并且已独立进化很长时间。因此,我们不支持将海南坡鹿引入泰国亚种的原分布区,重建已经绝灭的野生种群的设想和建议。我们建议将海南坡鹿与泰国亚种分别作为两个独立的进化显著单元(ESUs)进行管理。

2005年7～8月我们在塔什库尔干自然保护区对马可波罗盘羊的种群数量进行了调查。首先走访当地居民和保护区工作人员,确定盘羊分布范围,然后根据地形和水系,将调查区域分为Ⅰ、Ⅱ、Ⅲ、Ⅳ4个区。在每个调查区域沿河谷和沟谷设置随机样线,步行、骑马或开车沿样线搜寻盘羊,记录群体数量、年龄、性别、栖息地类型。通过调查以盘羊所在地为中心、直径200m的圆形样方中的地形和生态因子,确定盘羊利用的栖息地特征值,建立马可波罗盘羊对栖息地利用的模型。以1∶50000的地形图建立调查地区的数字高程模型（DEM）,用ArcView3.2的spatial analyst模块进行空间模拟与分析,计算出马可波罗盘羊分布区内符合模型中的海拔、坡度、坡向等要求的空间的范围和面积。通过计算每个调查地区的种群密度、适宜栖息地面积等数据,获得种群数量估计值,进而得到保护区内马可波罗盘羊的种群数量的估计值。调查结果表明,马可波罗盘羊分布在保护区西部达布达尔乡的皮斯岭、卡拉其古、赞坎沟等帕米尔高原地区;种群总数在1500～1700只;保护区内盘羊分布面积为4012.17km^2,适宜栖息地面积只有641.16km^2,可利用的栖息地仅482.67km^2,仅占分布区的12.03%。过牧、栖息地破坏、非法狩猎、疫病和交流障碍是盘羊生存的主要威胁因子。建议通过调整保护区边界、恢复栖息地、防止疫病、加强宣传、开展多边合作等措施来加强马可波罗盘羊的保护问题。

Bacterial leaf streak （BLS） of rice, caused by Xanthomonas oryzae pv. oryzicola （Xoc） is a worldwide destructive disease. Development of resistant varieties is considered to be one of the most effective and eco-friendly ways to control the disease. However, only a few genes/QTLs having resistance to BLS have been identified in rice until now. In the present study, we have identified and primarily mapped a BLS-resistance gene, blsl, from a rice line DP3, derived from the wild rice species Oryza rufipogon Griff. A BC2F2 （9311/DP3//9311） population was constructed to map BLS-resistance gene in the rice line DP3. The segregation of the resistant and susceptible plants in BCzFz in 1：3 ratio （Z2=0.009, Z20 05,1=3.84, P〉0.05）, suggested that a recessive gene confers BLS resistance in DP3. In bulked segregant analysis （BSA）, two SSR markers RM8116 and RM584 were identified to be polymorphic in resistant and susceptible DNA bulks. For further mapping the resistance gene, six polymorphic markers around the target region were applied to analyze the genotypes of the BC2F2 individuals. As a result, the BLS-resistant gene, designated as blsl, was mapped in a 4.0-cM region flanked by RM587 and RM510 on chromosome 6.
