本文调查了西班牙乌尔巴萨山脉和安迪亚山脉的13个金carabus亚属居群。在某些地区，线缕山花与锦绣山花的杂交品种高达16%。杂种最明显的特征是个体具有两个物种的诊断性形态特征的组合。多变量判别分析显示亲本种间存在差异，杂交品种为线状或splendens型。实验产生的杂交种与天然杂交种的范围相同。电泳研究对8种酶有可解释的结果，但只有一个性别连锁位点（G-6-pd）被固定在亲本物种的其他等位基因上，允许鉴定只有雌性杂交。对肠道蛋白水解酶的分析显示，凝乳胰蛋白酶有一个固定的差异，但这种酶的位点是性别连锁的。胰蛋白酶在几个位点上表现为多态，对杂交鉴定没有帮助。geogr……
We investigated 13 populations of the carabid subgenus Chrysocarabus in the Spanish mountains Sierra de Urbasa and Sierra de Andia. In some areas there were up to 16% hybrids between Carabus lineatus and Carabus splendens. Hybrids are best distinguished as individuals having combinations of morphological characters that are diagnostic for both species. Multivariate discriminant analysis showed a gap between the parental species, but hybrids were either C. lineatus-like or C. splendens-like. Experimentally produced hybrids lie in the same range as natural hybrids. Electrophoretic studies have interpretable results for eight enzymes, but only one sex-linked locus (G-6-pd) was fixed for alternative alleles in the parental species, allowing identification of only female hybrids. Analysis of proteolytic enzymes from the gut revealed one fixed difference for chymotrypsin, but the locus for this enzyme is sex-linked. Trypsin appears polymorphic at several loci and is not useful for identifying hybrids. The geogr...
