淀山湖水质及与环湖稻田农业面源污染的关系

对淀山湖主要进水和出水口水质进行年度定点监测; 同时, 布置田间试验, 研究不同施肥稻田田面水养分含量动态. 结果表明:淀山湖进出水口水体氨氮和总磷年平均质量浓度分别为 0.47 和 0.13 mg/L, 基本处于 Ⅴ 类水质标准; 进水口水质略劣于出水口, 不同进水口的水质也有很大差异. 进一步研究发现, 淀山湖水质的年度变化与稻田田面水养分的动态变化有密切的相关性, 表明农业面源污染对淀山湖水环境具有显著影响. 在环湖地区, 减少和控制农业面源, 是进一步改善淀山湖水环境质量的关键.

Long-term increases in clutch size in common snapping turtles (Chelydra serpentina) and diamondback terrapins (Malaclemys terrapin)

Clutch size (CS) is a well-studied life history characteristic, and optimal egg size theory predicts that CS should correlate positively with reproductive investment. Turtles are good subjects for studies of reproductive strategies because few turtle species exhibit parental care; therefore quantifying their short-term reproductive investment is mostly limited to measuring egg size and number. Clutch size is usually reported as an average value for each turtle population, and where CS variation is noted, it is usually attributable to variation in adult body size. In two long-term studies of ecologically dissimilar species we detected a dramatic increase in CS in a common snapping turtle (Chelydra serpentina) population and in a diamondback terrapin (Malaclemys terrapin) population. It is unknown whether these changes are due to either variation in adult body size or resource availability; but the temporal patterns we observed have apparently never been reported previously. These trends remain unexplained and should be explored further.

Die Wirkung des Toluidinblaus und der Thrombokinase auf den Vorgang der Thrombininaktivierung

Summary The disappearance of thrombin—formed in the blood, or added to serum-follows a manomolecular reaction-type. Heparin increases the reaction-velocity of this thrombin-inactivating process.Our investigation established that toluidine blue or kinase, which, according to the literature, bind heparin, strongly reduce the speed of thrombin-inactivation too. Therefore the heparin-binding capacity of these substances is also manifested in the decrease of thrombin-inactivation.
