ENROL IN THE SOCIETY

Earlé, R. A. 1981. Factors governing avian breeding in Acacia savanna, Pietermaritzburg, Part 2: Intrinsic factors. Ostrich 52:74-83.

The most important factor governing avian breeding in Acacia savanna is the body condition (protein reserve) of the bird. Breeding can take place only if the female has a large enough protein reserve to form eggs. The protein reserve is dependent on an adequate food supply which is once again dependent on climatic factors. Both the protein reserve and body weight of several species were found to be at their lowest towards the end of the breeding season. Moult and breeding were found to be largely separated in time. In most species examined testis activity was at its lowest between April and June and highest from September to January. Colius striatus showed a less seasonal pattern of testis activity while Nectarinia talatala showed very early testis activity and had fully active testes in May.

一足致炎大鼠双足伤害感受性的变化

大鼠一侧鹿角菜致炎足痛阈显著降低后,对侧非致炎足的痛阈出现显著降低、不变,和显著升高等变化。对侧非致炎足痛阈的这三种变化与致炎足痛阈降低幅度的大小显著相关。
