折翼蝠冬眠期几项生理常数的测定及分析

折翼蝠(Miniopterus schreibersii chinensis Thomas)在皖南地区数量较多、分布较广,是哺乳类中具冬眠习性的异温动物。这种异温动物的生理生态研究,国内极少报道。我们于1981年10月至1982年5月对折翼蝠冬眠期的几项生理常数做了测定和分析,目的在于了解它们在冬眠期间的生理变化及其与外界环境因子之间的相互关系,从而进一步探讨异温动物冬眠期的代谢规律,为休眠的理论和动物资源的利用提供一点参考资料。

ON THE MORPHO-PHYSIOLOGICAL INDICES OF LONG-WINGED BAT IN THE PERIOD OF HIBERNATION

The changes of the morpho-physiological indices of the long-winged bat (Miniopterus schreibersii chinensis Thomas) in the period cf hibernation were investigated.Fat coefficient, liver coefficient, relative fatness,hemoglobin content, red blood cell count and red cell diameter of 269 specimens were determined from October 1981 to May 1982. All the specimens were collected from the same cavern but in different months.The results can be summarized as follows:1. In late November when the bats begin to hibeinate all kir.cs cf physiological indices are higher than those of the other months, except that the liver coefficient is higher in December.In the period of hibernation these indices all fall apparently, especially in January to February,In late February stored fat tissue is largely consumed.In late March or early April when they wake up all kinds of the indices are lower than those of other months.These data are presented in Table 1-4 and figs.1-2 respectively.2. It is also mentioned that the change of blood content has taken place by surveying the dividing picture of haemopoiefic cell and the fragility of red blood cells were also tested from winter to sprier(Table 5).
