Abstract

Recently, the focus within microevolutionary studies has been on the ecological divergence of populations. One subset of this research field includes studies on local adaptation. This approach is useful for studying whether or not adaptive spatial variation takes place in a metapopulation context. There is growing body of research studying local adaptations of populations, and much of this has used a formal test for assessing the existence of local adaptation. According to Kawecki and Ebert (2004), the “Local vs. foreign” criterion is fulfilled if the local population has higher fitness than other populations in its own locality and “Home vs. away” is fulfilled if a population has higher fitness in the sympatric than allopatric environment. Interestingly, interpretation of results not fulfilling these criteria has received scant attention even though the question of how to measure local adaptation is vital for the study field. At present, there is an extensive volume of published results showing other kinds of patterns than those proposed by the “Local vs . foreign” or “Home vs . away” criteria. Here, we highlight one of these alternative patterns that we believe may have an adaptive background and may show local adaptation not recognized by the above-mentioned criteria.

在局部适应研究中被忽视的模式:当异域地点的草更绿时
近年来,微进化研究的重点是种群的生态分化。该研究领域的一个子集包括对当地适应的研究。这种方法对于研究在元种群背景下是否发生自适应空间变化是有用的。有越来越多的研究机构在研究种群的地方适应性,其中很多都使用了一种正式的测试来评估地方适应性的存在。根据Kawecki和Ebert(2004)的研究,如果本地人口在本地区的适应度高于其他人口,则满足“本地vs.外国”标准;如果一个人口在同域环境中的适应度高于异域环境,则满足“主场vs.客场”标准。有趣的是,对不符合这些标准的结果的解释很少受到关注,尽管如何测量局部适应的问题对研究领域至关重要。目前,有大量已发表的结果显示了其他类型的模式,而不是“局部vs。或者“国内vs .国外”。”标准。在这里,我们强调了其中一种我们认为可能具有适应性背景的替代模式,并且可能显示出上述标准未识别的局部适应性。
