北极及长白山苔原带昆虫多样性研究进展

摘要

苔原是冷湿型极地自然景观类型,全世界现代苔原仅分布于北半球.综述北极苔原带昆虫的物种组成:部分苔原带种类存在较明显的形态适应,北极苔原带温度和紫外线对昆虫有较大影响,较低温度和较短的生长季节是导致昆虫多样性较低和形态变化的主要原因,当温度升高时昆虫能快速扩散到北极苔原带;综述长白山苔原带昆虫种类组成,侵入种及侵入原因,直翅目蝗虫种群适应变化和天牛、食蚜蝇、蝶类访花昆虫种类及其访花习性等研究进展.%Tundra is the cold and moist polar natural landscapes,all extant tundra distribute the Northern Hemisphere.The species composition of insect is summarized in arctic tundra,there are obviously morphological adaptabilities of some insect species,the effects of temperature and ultraviolet radiation on insects in arctic tundra.It is shown that the lower temperature and the shorter season of growth are considered to be the main causes of lower insect diversity and morph,and insect can come into arctic tundra greatly when temperature is high.Meanwhile,the species composition,invasive species and invasive reason,morphological adaptabilities of grasshopper and flower-visiting behavior of longhorn beetle,Syrphidae,butterfly are introduced in tundra of Changbai Mountain.
