由于保护生物学家必须经常处理小种群,近亲繁殖(小种群规模的常见后果)在许多遗传管理计划中发挥了核心作用。然而,“近亲繁殖”这个词有几个,往往是相互矛盾的含义,并未能区分这些含义造成了许多误解的作用,近亲繁殖的遗传管理。本文讨论了近亲繁殖的三种不同的生物学意义:(1)近亲繁殖是个体父系和母系共有祖先的量度;(2)近亲繁殖是有限种群中遗传漂变的量度;(3)近亲繁殖是繁殖种群中交配系统的量度。这些不同的措施近亲繁殖的区别和使用进行了讨论和说明与一个工作的例子,北美圈养人口的斯皮克的瞪羚(Gazella spekei)。结果表明,这些不同的含义的单词近亲繁殖必须保持分离,否则可能会发生错误的管理建议和评价。从积极的一面来看,近亲繁殖的不同措施如果联合使用,可以成为一个强大的管理工具,因为它们衡量的是不同的生物现象。
Because conservation biologists must frequently deal with small populations, inbreeding (a frequent consequence of small population size) has played a central role in many genetic management programs. However, the word “inbreeding” has several, often contradictory meanings, and a failure to distinguish among these meanings has caused much misunderstanding on the role of inbreeding in genetic management. Three different biological meanings of inbreeding are discussed in this paper: (1) inbreeding as a measure of shared ancestry in the paternal and maternal lineages of an individual; (2) inbreeding as a measure of genetic drift in a finite population, and (3) inbreeding as a measure of system of mating in a reproducing population. The distinction and use of these different measures of inbreeding are discussed and illustrated with a worked example, the North American captive population of Speke’s gazelle (Gazella spekei). It is shown that these different meanings of the word inbreeding must be kept separated, otherwise erroneous management recommendations and evaluations can occur. On the positive side, the different measures of inbreeding when used jointly can be a powerful management tool precisely because they measure different biological phenomena.
