物种间相互作用的地理变异对分布有重大影响。这种变化的影响对于入侵物种尤其明显，其中竞争能力的变化可以影响入侵的成功和影响。我们测试的假设，共存或排斥的居民蚊子埃及伊蚊的结果，从当地种群的白纹伊蚊的入侵与A的竞争性相互作用的变化。埃及人。我们还研究了在这些竞争性的相互作用中的繁殖力的大小关系的变化的作用。我们比较了九个北美种群的竞争能力。albopictus，三种立地类型各三个种群：A. aegypti继A.白纹伊蚊入侵，A.白纹伊蚊入侵和A.白纹伊蚊A.埃及人。各A. albopictus种群和A.在实验室微观世界中，采用响应面设计对埃及人口进行了测试。结果表明，A.白纹伊蚊，但没有强格局的网站类型。灭绝的网站有陡峭的平均生殖力大小的关系比共存网站和异域的网站，但这并没有转化为上级人口的表现。某个人A.白纹伊蚊种群对A. aegypti或对A.埃及伊蚊，但竞争效应和反应不相关。这些结果表明，种群间的竞争能力的差异。albopictus可能只能部分解释与A.埃及人。区域间的环境差异可能影响到A.影响其入侵成功率和影响。
Geographic variation in species interactions can have major effects on distributions. Effects of such variation can be particularly evident for invasive species, in which variation in competitive ability can influence invasive success and impacts. We tested the hypothesis that coexistence or exclusion of the resident mosquito Aedes aegypti results from variation among local populations of the invasive Aedes albopictus in competitive interactions with A. aegypti. We also examined the role of variation in fecundity-size relationship in these competitive interactions. We compared competitive abilities of nine North American populations of A. albopictus, three populations from each of three site types: extinction of A. aegypti following A. albopictus invasion, coexistence following A. albopictus invasion, and A. albopictus allopatric to A. aegypti. Competition among larvae from each A. albopictus population and a single A. aegypti population was tested in laboratory microcosms in a response-surface design. We found interpopulation differences in competitive ability of A. albopictus, but no strong patterns among site types. Extinction sites had steeper average fecundity-size relationships than coexistence sites and allopatric sites, but this did not translate into superior population performance. Certain individual A. albopictus populations had exceptionally large competitive effects on A. aegypti or poor competitive responses to competition from A. aegypti, but competitive effect and response were not correlated. These results suggest that interpopulation variation in the competitive ability of A. albopictus may only partly explain geographic pattern of coexistence with or extinction of A. aegypti. Environmental differences among regions may affect the competitive ability of A. albopictus and influence its invasion success and impact.
