摘要
生物多样性与生态系统功能的关系是当前备受生态学界关注的焦点。大多数的生物多样性与生态系统功能研究中,人们常用物种多样性代替生物多样性,但不同种在生理生态和形态特性等方面存在较大差异。因而,生态系统功能不仅依赖物种的数目,而且依赖于物种所具有的功能特征,即功能多样性。功能多样性指影响生态系统进程和功能的生物多样性的构成因素。
In order to reveal the difference of functional traits functional traits of 17 ant species were measured. The results of ants and study on ant' s functional diversity, the were as follows : ( 1 ) There was difference of func- tional traits in terms of resource utilization among ant species. Pachycondyla rufipes (Jerdon) was the largest, and Technomyrmex albipes (Smith) was the smallest one in the aspect of food consumption amount. Technomyrmex bi- color Emery and lridomyrmex anceps ( Roger), Camponotus nicobarensis (Mayr) and Pachycondyla zhengi Xu, Gnamptogenys bicolor (Emery) and Aphaenogaster beccarii Emery showed similarity in food consumption amount. (2) In the aspect of mode of resource utilization, Oecophylla smaragdina (Fabricius) has the longest relative legs, but their functions were prior to nesting, the 2 species of Aphaenogaster, 3 species of Camponotus and the Iridomyrmex anceps (Roger) could run fast to acquire resource, the rest 10 ant species had better resource utiliza- tion abilities in complex habitat. The overall trend showed that the species from the same family and genus had the similar traits in terms of food consumption amount and mode of resource utilization than those from different family or genus; the reason of difference was mainly due to the significantly different body sizes regardless the family or genus.
