We simulated a shelterwood forest regeneration treatment by reducing basal area,and monitored the response of an avian community in oak–hickory forest on the southern Cumberland Plateau,northern Alabama,*** used five treatments:control(no removal),clear-cut(100%removal),and 25,50,and 75%removal of basal *** mapping was used to quantify bird community between mid-April and July of both 2002 and *** variables were recorded at each *** residual basal area and canopy cover showed three distinct conditions after treatment:closed canopy,open forest,and *** microclimate varied among treatments:air temperature was highest in clear-cut plots and lowest in control plots,whereas soil moisture had the opposite pattern.A total of 71 bird species were detected,with 36 of them defending *** density,species richness,and Shannon diversity index differed among the treatments;the relationship between these bird community indices and the level of basal area removal was quadratic,lowest in the clear-cut plots and highest in the intermediate *** species richness was similar among the control,25,50,and 75%removal treatments,species composition *** richness difference among treatments became smaller in the second year post-treatment(2003)with an increase in bird density and richness occurring in the clear-cut plots.

我们于2006年7月对分布于青藏高原东部若尔盖高寒湿地的7只高原林蛙(Rana kukunoris)进行了追踪研究。Monte-Carlo模拟表明:在研究期内高原林蛙的运动是随机的,还没有开始迁移。高原林蛙的平均运动距离为7.1m,雌雄运动距离没有差异。95%和50%Kernel家域分别为796.2m2±704.0m2和119.9m2±94.6m2,MCP家域为157.9m2±119.5m2。雌雄高原林蛙生境选择存在差异,雄性倾向于在洞穴较多的生境中运动和隐蔽,而雌性倾向于在草丛中运动和藏匿;早晨高原林蛙选择地面温度较高、相对湿度较大的微生境活动,雌雄活动点的空气温度、相对湿度和植被高度没有显著差异。追踪个体的微生境利用表明:高原林蛙和哺乳类洞穴具有很强的相关性。

影响无尾两栖类活动的因素很多,水体是最主要的因素之一。本研究采用样线法,分别于2006年7月和9月下旬对若尔盖季节性水塘周边高原林蛙(Rana kukunoris)的活动特征进行了研究。样线宽2m,长70-150m,采用十字交叉法,基本按照东、南、西、北、东北、西北、东南、西南方向设置8条样线。结果表明:夏季高原林蛙主要在水塘周边活动,高原林蛙遇见率与水塘距离呈显著负相关(Pearson,成体:r=?0.479,P0.05),水塘周边高原林蛙的遇见率很低,远离水塘的高原林蛙偏向选择泉眼活动。

Background:The measurement of circulating tumor DNA(ctDNA)has been studied in several malignancies,including metastatic pancreatic cancer,but less is known about its utility in monitoring treatment response and recurrence in resectable pancreatic ***:We conducted a systematic review of the literature examining the association of ctDNA with overall survival(OS)and disease-free ***:Five articles met our exclusion *** and/or postoperative ctDNA was found to be associated with decreased OS and recurrence-free ***:ctDNA has the potential to be used as a prognostic biomarker and to guide therapy in resectable pancreatic cancer.
