, 2001 两观测者独立观测了分别采自洪湖的 1 75尾和洞庭湖的 1 6 8尾鲫样本的鳞片和耳石 ,结果显示鳞片适于鉴定年龄组成简单、生长较快的洞庭湖鲫种群的年龄 ,两观测者年轮读数的总吻合率可达 90 5% ,与耳石上年轮读数的吻合率也可高达 91 7% ;但用鳞片鉴定年龄结构复杂、生长缓慢的洪湖鲫种群年龄 ,两观测者总吻合率只有 50 9% ,各龄组吻合率随年龄上升而迅速下降 ,与耳石上年轮读数总吻合率也仅为 56 6 % ,存在比耳石低估高龄个体年龄的问题。用耳石鉴定鲫年龄具有易于识别、精确度高的优点 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2007 【目的】探讨正常人晶状体随年龄的增长对跟前段轴向空间结构的影响。【方法】采用跟前段光学相干断层扫描仪（AS—OCT）测量正常人105例（105只眼）前房深度（ACD）和晶状体厚度（LT）；比较它们性别间的差异，采用直线相关与回归分析方法分析年龄与ACD、LT的相关关系。【结果】正常人ACD、LT的平均值分别为：2．97（S=0．32）mm、4．21（S=0．43）mm。女性ACD为2.87（S=0．33）mm比男性3．07（S=0．29）mm浅（P=0．001）；LT性别间差异无统计学意义（P=0 ...

红尾沙鼠(Meriones libycus)的年龄鉴定及种群年龄组成
, 2007 选用2004年4~10月在新疆吐鲁番盆地采集的红尾沙鼠标本,用胴体重为年龄划分指标,将红尾沙鼠划分为5个年龄组。Ⅰ.幼体组:雌性120 g,雄性>135 g。同时探讨了胴体重与体重、体长及尾长之间的关系。结果显示,体重与胴体重之间存在最为显著的线性关系,且各组间体重交叉不大,故在野外当技术条件受到限制不能称量胴体重时,体重也可作为划分红尾沙鼠相对年龄的指标。种群年龄结构的季节变化特征为:春季Ⅲ,Ⅴ组占优势;夏季和秋初Ⅰ,Ⅱ组数量明显增加,秋季除老体组外 ...
