东北林业大学城市林业示范基地弹尾虫水平分布研究

Horizontal distribution of collembola in urban forest foundation of Northeast Forest University

对东北林业大学城市林业示范基地8种植被类型下弹尾虫水平分布进行研究,获取弹尾虫7科10属801只,其中优势科为球角■科、等节■科、疣■科和棘■科;常见科为圆■科;稀有科为长角■科和鳞■科。优势属为球角■属、德■属、疣■属和棘■属;常见属为小圆■属;稀有属为长■属、鳞长■属、裸长■属、叶■属和鳞■属。等节■科德■属在林场8种植被类型中均有分布,是8个生境的代表类群,属广布型类群。鳞■科是水曲柳的特有科,是该生境的代表。数量特征方面,黄檗林中弹尾虫数量最多,榆树林中最少。类群特征方面,水曲柳中弹尾虫类群最丰富,包含5科6属;最少为蒙古栎,包含2科2属。

Sampling sites were set in Urban Forest foundation of Northeast Forest University, where there are 8 habitats. In total, 801 specimens were collected belonging to 7 families, 10 genera. Among them, Hypogastruridae, Isotomidae, Neanuridae and Onchiuridae are dominant families, Sminthuridae is the common family, while Entomobryidae and Tomoceridae are rare families. Hypogastrura, Desoria, Neanura and Onychiurus are dominant genera, Srninthurinus is the common genus, while Entomobrya, Lepidocyrtus, Sinella, Lobella and Tomocerus are rare genera. Desoria is distributed in 8 habitats, being the representative of all habitats. Tomoceridae is the special family for Fraxinus mandshurica. The number of Collembola is the highest in Phellodendron amurense, lowest in Ulmus pumila. As for group number, the richest in Fraxinus mandshurica, including 5 families and 6 genera; the poorest in Quercus mongolica, including 2 families and 2 genera.
