Dissertation Research: An Investigation of the Apparent Competitive Exclusion or Reduction of Anolis carolinensis byA. sagrei in Non-Wetland Habitats in Southern Florida

种间竞争的令人信服的实地示范 是罕见的，尽管理论家经常呼吁精心设计的 田间试验 即使种间竞争很明显， 行为干预的相对重要性， 资源的竞争性开采仍存在争议。 的 棕色变色龙阿诺利斯（Anole Anolis）最近在佛罗里达南部殖民 sagrei和同时下降的人口的土著 绿色变色龙Anolis carolinensis表明竞争激烈 在这些形式之间。 这将按照以下方式进行测试： 将在现场建造围栏，并储存 这两个物种中的一个或两个。 人口将 在两年内每月进行一次普查， 关于生长和繁殖的数据。 竞争将 明确地证明，如果一个种群的平衡种群 或在两种围隔中两种都显著降低 而不是在单一物种的环境中。 如果发现有竞争， 人口、生殖和生长数据，以确定 竞争最激烈的年龄/性别类别，以及 从而推断其机理。

Convincing field demonstrations of interspecific competition are rare, despite frequent appeals by theorists for well-designed field experiments. Even when interspecific competition is clear, the relative importance of behavioral interference and competitive exploitation of resources remain in dispute. The recent colonization of southern Florida by the brown anole Anolis sagrei and the simultaneous decline of populations of the native green anole Anolis carolinensis suggest severe competition between these forms. This will be tested as follows: Large enclosures will be constructed in the field and stocked with populations of one or both of these species. Populations will be censused monthly over a period of two years in order to collect data on growth and reproduction. Competition will be unequivocally demonstrated if the equilibrium populations of one or both species are significantly lower in two-species enclosures than they are in one-species enclosures. If competition is found, it will be possible by examination of the demographic, reproductive, and growth data to identify the age/sex classes upon which competition most heavily falls, and thus deduce its mechanism.
