以木薯、木瓜的叶片为饲料,在室温(25-28℃)条件下通过对朱砂叶螨的饲养和生命活动观察而组建了其室内种群生命表,并计算其内禀增长率及其它种群特征参数。在木薯和木瓜上,朱砂叶螨的内禀增长率(rm)分别为0.2576和... 以木薯、木瓜的叶片为饲料,在室温(25-28℃)条件下通过对朱砂叶螨的饲养和生命活动观察而组建了其室内种群生命表,并计算其内禀增长率及其它种群特征参数。在木薯和木瓜上,朱砂叶螨的内禀增长率(rm)分别为0.2576和0.2985,周限增长率(λ)分别为1.2938和1.3479,净增殖率分别为26.3870和24.0208,世代平均历期(T)分别为13.2920天和11.1739天,种群加倍时间(t)分别为2.6908天和2.3221天;在稳定年龄组配中,未成熟期所占比例分别为90.9271%和91.8514%,成熟期所占比例分别为9.0735%和8.1546%。从生命表中可看出,木薯和木瓜是朱砂叶螨的适宜寄主,在两寄主上,朱砂叶螨具有较大的种群发展潜力。 展开更多

In the previous paper <a href="#ref.1" target="_blank">[1]</a>, the application of the general thermodynamic theory was considered to biological systems. The nature of living matter has been presented from the mesoscopic to the macroscopic point of view, for different time scales (ontogenetic and phylogenetics). Herein, we continue with this application, and present three characteristics of life in the form of statements or postulates. The first characteristic describes the probability of survival against aging. In particular, the behaviour of life is shown as an independent mode of aging. The second characteristic refers to the adaptation of the species according to the environment. The relationship between the phenomenon of organic homeostasis and the origin of the clinical parameters that define health is highlighted. And finally, the third characteristic applies the principle of negentropy to describe evolution. A representative model is given as an example of each postulate. 展开更多
