Determination on Blood Physiological Parameters of Apodemus agrarius

The study was conducted to investigate the characteristics of blood physiological parameters of Apodemus agrarius( A. agrarius). Blood physiological parameters of 10 A. agrarius( half male and half female) were determined by automated hematology analyzer. Results showed that difference of A. agrarius hematokrit( HCT) between male and female was significant( P <0. 05),and differences of all the other blood physiological parameters between male and female were not significant( P > 0. 05). In the study,blood physiological reference value of A. agrarius was set up,which provided a basis for the bio-research and prophylaxis and treatment of A. agrarius.

Food Selection of Apodemus peninsulae under Artificial Rearing Condition

[Objective]The paper aimed to screen the poison bait and lure suitable for controlling Apodemus peninsulae. [Method]A. peninsulae was reared individually in a single cage,to observe its feeding conditions. [Result] A. peninsulae preferred carrot and cucumber,followed by peanut,and rat diet was the last choice. [Conclusion] Carrot and cucumber could be used to prepare poisoning bait for controlling A. peninsulae,in order to improve rat capture efficiency.

Comparison of Oxygen Consumption between Clethrionomys rufocanus and Apodemus agrarius

[Objective] The paper was to find out the difference in oxygen consumption between Clethrionomys rufocanus and Apodemus agrarius. [Method] The oxygen consumption value of C. rufocanus and A. agrarius was measured using improved closed pressure breathing apparatus,and the oxygen consumption rate was calculated. [Result] The oxygen consumption of C. rufocanus and A. agrarius increased with the increasing body weight,while the increase amplitude of A. agrarius was relatively smaller. The oxygen consumption rate decreased with the increasing body weight. [Conclusion]The result provides a biological basis for breeding and research of experimental rats.

Rodent Fauna in Southeast Forest Region of Heilongjiang Province of China and Its Damage on Agriculture and Forestry

[Objective]The paper was to understand the rodent fauna in southeast forest region of Heilongjiang Province and its harm to agriculture and forests.[Methods]The southeast forest region of Heilongjiang Province was surveyed from March2008 to December2013 using night trap method combined with integrated collation of literature. [Result]There were totally 21 species of rodents in southeast forest region of Heilongjiang Province,belonging to 16 genera,8 families,3orders,and the fauna was mainly consisted of palaearctic realm; in terms of captured number,Clethrionomys rufocanus was the dominant species in forest region,while Apodemus agrarius was the dominant species in fields. The number of rodents was closely related to stand age,and the density of rodents was lower in the forest land with longer stand age and greater density. Rodents caused greater harm to timber forest and middle-aged forest than economic forest and young forest,and their damage on newly planted seedlings was particularly greater. The number of rodent population was the highest in summer,but the smallest in spring,while its interannual changes were stable. [Conclusion]The study provided a scientific basis for forestry management and rodent control,which also offered the basic biological data for the study of rodents.

新生代优秀乒乓球运动员林昀儒技战术特征研究

本文运用四段指标评估法、录像观察法等方法对林昀儒与四位中国乒乓球队员的4场比赛进行观察统计,深入研究与分析林昀儒的技战术运用特点,旨在为国乒训练提供数据支持。结果表明:①用四段指标评估法对林昀儒的技战术进行分析,发现其优势在发抢段和接抢段,劣势为相持Ⅰ段和相持Ⅱ段;②在发抢段中,林昀儒发球以侧旋台内短球为主,第三板使用的主要技术为正、反手拉球和正、反手反攻,进攻路线多为对手斜线;③在接抢段中,林昀儒在接发球时反手拧拉技术使用最多,其次是通过摆短限制对方上手,落点以斜线为主,第四板衔接时多以正、反手反攻为主要使用技术;④在相持阶段中,林昀儒使用的主要技术为反攻、拉、防守,回球线路多变,但缺乏稳定性,相持能力较差。
