本研究的主题是四头无腹蛛背棘数目多态性的生态遗传学研究。在这里，我们提出的信息，其生态和背棘的变化，作为背景的后续publications.Estimating年龄从耳石是受到几个严重的错误，和脊柱部分是值得怀疑的。我们估计世代时间约为1年使用长度频率分布。背棘数量从1到7不等，但以4和5棘的变体为主。多态性是普遍存在的;在有样本可供比较的情况下，变体频率至少在50年内保持相对稳定。性别比是高度可变的网站之间，并在特定网站的样本。然而，变体频率与性别和年龄无关。在一天中不同时间、潮汐水位、一年中的几个月以及几年之间采集的样本中，形态频率是均匀的。它们也是均匀的微栖息地，我们在一个E采样...
The subject of our research is the ecological genetics of a polymorphism for dorsal spine number in Apeltes quadracus. Here we present information on its ecology and on dorsal spine variation, as background for subsequent publications.Estimating age from otoliths is subject to several serious errors, and spine sections are questionable. We have estimated generation time at about 1 year using length frequency distributions. Dorsal spine number varies from one to seven, but the four-and five-spined morphs predominate. The polymorphism is ubiquitous; where samples are available for comparisons over time, morph frequencies have remained relatively constant for at least 50 years. Sex ratio is highly variable among sites and among samples at particular sites. However, morph frequencies are independent of sex and age. Morph frequencies are homogeneous among samples taken at differing times of day, tide levels, months within a year, and among years. They are also homogeneous among microhabitats we sampled in an e...
