We analysed the diversity of the cytochrome b gene in Iberian ibex (Capra pyrenaica) populations in the southern Iberian Peninsula by sequencing a fragment (987 bp) of this gene in 347 ibex from 10 population nuclei in Andalusia. We found 25 different haplotypes, which account for 64.10% of all haplotypes thus far described for the species (n = 39). All ibex populations other than those from Sierra de Loja shared haplotype EU081020, which was also the most frequent. Twenty haplotypes (80%) were present exclusively in just one population. Of the studied populations, ibex from the Sierra Nevada Natural Space had the greatest genetic diversity in this marker, which was found to harbour 17 cyt b haplotypes. Phylogenetic analyses based on the cytochrome b marker do not support the subspecific classification of this taxon proposed at the beginning of the twentieth century, although three distinct management units can be distinguished. Finally, we discuss the implications of our results on the management of this species. Although the results presented do not describe the structure of the population or the gene flow, it gives an accurate picture of the diversity of this mitochondrial marker, which can be considered a reflection of the historical processes that these populations have undergone.

安达卢西亚伊比利亚野山羊细胞色素b的遗传多样性

我们通过对来自安达卢西亚的 10 个种群核的 347 只 ibex 中的该基因的片段 (987 bp) 进行测序，分析了伊比利亚半岛南部伊比利亚山羊 (Capra pyrenaica) 种群中细胞色素 b 基因的多样性。我们发现了 25 种不同的单倍型，占该物种迄今为止描述的所有单倍型的 64.10%（n = 39）。除了来自 Sierra de Loja 的那些之外的所有 ibex 种群都共享单倍型 EU081020，这也是最常见的。二十个单倍型 (80%) 仅存在于一个群体中。在研究的种群中，来自内华达山脉自然空间的 ibex 在该标记中具有最大的遗传多样性，发现其包含 17 个细胞色素 b 单倍型。尽管可以区分三个不同的管理单位，但基于细胞色素 b 标记的系统发育分析不支持 20 世纪初提出的该分类群的亚种分类。最后，我们讨论了我们的结果对该物种管理的影响。尽管所呈现的结果并未描述种群结构或基因流，但它准确描绘了这种线粒体标记的多样性，可以认为是这些种群所经历的历史过程的反映。
