約3年間凍結保存したマスコビーダック精液の受精率について [PDF]
, 1981 横取り法によって採取したマスコビーダック粕液をグリセリンの最終濃度7%の5.5%ブドウ糖・卵黄希釈液で4倍に希釈し、急速法によって-196℃の液体窒素申に約3年間(1032～1060日間)凍結保存し、融解後の精子活力、畸形率および同精液使用による受精率を調べた結果は次の如く要約される。1.液体窒素中に1032～1060日間凍結保存したマスコビーダック精子のTrial 1, 2の融解後の活力は60～75%、平均68.8%(++以上)であった。2.又同期間凍結保存したTrial 1,2の融解彼の畸形率は7 ...

Conservation Biology, EarlyView.Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...

, 2000 萼花臂尾轮虫的交配行为大致可分为 5个阶段。除雌雄性比为 1∶ 2和 1∶ 3时混交雌体的受精率为 1 0 0 %外 ,其余性比下混交雌体的受精率皆无显著的差异。可受精的混交雌体百分率和具受精能力的雄体百分率皆随年龄的增大而下降。所有的混交雌体在出生后的 4 h内均易于受精 ;以后随着龄长 ( X,h)的增加 ,可受精的混交雌体百分率 ( Y,% )呈非线性下降 :Y=1 66.6386-1 7.81 3X+0 .4 837X2。当龄长达 1 8h时 ,所有的混交雌体皆不易受精。雄体在出生后的 8h内
