- High Symbiont Relatedness Stabilizes Mutualistic Cooperation in Fungus-Growing Termites
[作者:Aanen, DK; Licht, HHD; Debets, AJM; Kerstes, NAG; Hoekstra, RF; Boomsma, JJ,期刊:Science, 页码:1103-1106 , 文章类型: Article,,卷期:2009年326-5956]
- It is unclear how mutualistic relationships can be stable when partners disperse freely and have the possibility of forming associations with many alternative genotypes. Theory predicts that high symbiont relatedness sho...
