Mobile elements represent a unique and under-utilized set of tools for molecular ecologists. They are essentially homoplasy-free characters with the ability to be genotyped in a simple and efficient manner. Interpretation of the data generated using mobile elements can be simple compared to other genetic markers. They exist in a wide variety of taxa and are useful over a wide selection of temporal ranges within those taxa. Furthermore, their mode of evolution instills them with another advantage over other types of multilocus genotype data: the ability to determine loci applicable to a range of time spans in the history of a taxon. In this review, I discuss the application of mobile element markers, especially short interspersed elements (SINEs), to phylogenetic and population data, with an emphasis on potential applications to molecular ecology.
移动元件是分子生态学家一套独特且未得到充分利用的工具。它们本质上是无平行进化特征，能够以简单高效的方式进行基因分型。与其他遗传标记相比，对使用移动元件生成的数据进行解读可能较为简单。它们存在于各种各样的分类单元中，并且在这些分类单元内广泛的时间范围内都很有用。此外，它们的进化模式赋予了它们相对于其他类型多位点基因型数据的另一个优势：能够确定适用于一个分类单元历史中一系列时间跨度的基因座。在这篇综述中，我将讨论移动元件标记，特别是短散在元件（SINEs）在系统发育和种群数据中的应用，重点是在分子生态学中的潜在应用。
