Birds living at high latitudes perceive the photoperiod through deep-brain photoreceptors (DBP) located in deep-brain neurons. During long photoperiods the information transmitted by these photoreceptors increases the activity of the hypoth...
Intraspecific and interspecific comparison of toxicity of ladybirds (Coleoptera: Coccinellidae) with contrasting colouration [0.03%]
对比色差异瓢虫( Coleoptera: Coccinellidae )的种内和种间毒性比较研究

Ladybirds (Coccinellidae) use toxic compounds, mostly alkaloids in their haemolymph, for defence against predators and other enemies. The toxicity of ladybirds to predators cannot be directly assessed because predators show avoidance reacti...
Cycle of the sexual segment of the kidney: histological insights into the role of the urinary tract in the reproduction of male Notomabuya frenata (Squamata: Scincidae) [0.03%]
肾性段的周期：组织学对尿道在雄性Notomabuya frenata（Squamata: Scincidae）繁殖中的作用的见解
