查询词典 stable distribution

Based on the distribution of the genera in the world,the eight distribution types of the genera were divided.In addition,the distribution characters of the Perlidae in China were also probed preliminarily.So far two subfamilies,four tribe and twenty genera have been found in China.Ten of them,of which three genera are endemic to China,are the Oriental genera;one Palaearctic genus;three Oriental-Palaearctic genera;one Oriental-Nearctic genus;four Oriental-Palaearctic-Nearctic genera and one Oriental-Palaearctic-Nearctic-Afrotropical genus.

Purpose In this research, we applied three modeling methods to strive for accurately forecasting thepotential distribution of invasive species-Solenopsis invicta in China. Furthermore, we also researchedthe relationship between potential geographic distribution of S. invicta and environmental factors indetail to understanding how environment factors restricted distribution of Solenopsis invicta innon-suitable areas of Chinese mainland. The achievement of research provides a theoretical basis, whichcould guild the next step for the prevention and control stratagem ofS.
