Abstract

Harvester ants (P. badius) were collected from 49 localities in the southeastern U.S. Amylase and naphthylamidase activities were assayed by gel electrophoresis, and the frequencies of alleles controlling electrophoretic variation were calculated. Soil samples were analyzed and plotted against allelic frequencies. Climatographic and genetic data were analyzed by the method of principal components. Statistically significant correlations were found to occur between the patterns of genetic variation, and between the genetic and environmental patterns. These correlations are consistent with a selective basis for the maintenance of isozyme polymorphisms.

摘要

收获蚁(巴氏收获蚁)采自美国东南部的49个地点。通过凝胶电泳测定淀粉酶和萘基酰胺酶的活性,并计算控制电泳变异的等位基因频率。对土壤样本进行分析,并将其与等位基因频率作图。通过主成分分析法对气候数据和遗传数据进行分析。发现遗传变异模式之间以及遗传模式与环境模式之间存在统计学上的显著相关性。这些相关性与同工酶多态性维持的选择基础一致。
