捕食性颏花金龟口器形态的适应进化及功能研究(鞘翅目:金龟科:花金龟亚科)

颏花金龟为捕食性,是花金龟亚科12族中食性最为特殊的类群,以其下唇的前颏极度扩大而得名。依据捕食对象及对应形态变异类型的不同,其可分为蚁食性和蚜食性两类。由于颏花金龟的食性异于其他种类花金龟的植食性,栖息环境也有极大的不同,故其口器适应进化出诸多形态类型。通过比较颏花金龟、花金龟亚科其他种类、其他植食性金龟(丽金龟和犀金龟两个亚科为代表)以及典型肉食性甲虫口器的形态,对颏花金龟口器特殊结构及功能进行了分析,并初步探索了取食机制及颏花金龟的生存策略。

Selection with two alleles and complete dominance

For a plant selection model with frequency-independent viabilities, fertilities and selfing rates, it is shown that apart from global fixation, for certain parameter combinations a protected polymorphism and facultative fixation (either allele may become fixed according to initial frequencies) may both occur. Facultative fixation requires different selling rates for the dominant and recessive type. Protection of the polymorphism requires resource allocation for male and female function. In this connection the problem of purely genetically caused population extinction is discussed.
For general frequency dependence and regular segregation, the chances for establishment of a completely recessive gene are compared to those of a completely dominant gene. It is proven that the process of establishment of the recessive gene, despite a fitness advantage, may be considerably endangered by drift effects if random mating prevails. The recessive gene may reach the same effectivity in establishment as a dominant gene, only if the recessive homozygote mates exclusively with its own type during the period of establishment.

Inception of the Modern Public Health System in China and Perspectives for Effective Control of Emerging Infectious Diseases: In Commemoration of the 140th Anniversary of the Birth of the Plague Fighter Dr. Wu Lien-Teh

In this article, we systematically review Dr. Wu Lien-Teh's academic achievements and outstanding contributions in the prevention and control of the plague epidemic in northeast China and introduce the development of the earliest public health epidemic prevention system in China in order to commemorate the 140th anniversary of Dr. Wu Lien-Teh's birth. We hope that this article will provide insights into the effective prevention and control of emerging infectious diseases as well as the current worldwide pandemic of COVID-19, facilitating the improvement and development of public health systems in China and around the globe.
