Dr. Waage's research has three related goals. Although the work focuses on one species of insect, it has wider relevance to the question of how habitat and female behavior interact and how they in turn influence male behavior, and it contributes to the general methodology for experimental testing of hypotheses under field conditions. Dr. Waage's first goal is to continue to develop methods for testing hypotheses about the causes of behavior under field conditions. This is important because many species cannot be raised in captivity and because experiments done under simplified laboratory conditions may often not reveal much about about what goes on in nature. Dr. Waage's choice of damselflies as research animals stems from his familiarity with their biology and his ability to manipulate individuals and their habitat. For example, his research will involve creating, removing, and altering egg-laying (oviposition) sites to test what features of them or their locations are important for choice of these sites. Determining what influences the choice of oviposition sites by females and by males of the damselfly Calopteryx maculata- is Dr. Waage's second goal. Oviposition sites (vegetation in streams) are key resources for individuals of both sexes. Females use them as places to put their eggs, and males defend them and use them as places to encounter females. Dr. Waage will investigate what features of oviposition sites and surrounding vegetation make them attractive to males and females. He will also investigate why there is so much temporal and spatial variation among sites in their use by males and females. Answering the simple question of what determines oviposition-site choices by C. maculata actually may help explain much of male and female behavior and the interactions between the sexes. Although this work is on one species, the findings will contribute to the general body of information on how insects deal with finding and exploiting resources. The third goal of this project is to test a number of general ideas currently in the behavioral-ecology literature. Like most rapidly growing disciplines, theory in behavioral ecology is far ahead of its testing. Dr. Waage will focus on the idea that female behavior (for example, where they lay eggs) may underlie or determine much of male behavior (for example, male choice of places to look for females, or competition among males for access to such places). Behavioral ecology has long been biased towards explaining things from the male perspective. These damselflies seem to be ideal animals with which to explore how male and female behaviors are related. Together with Dr. Waage's previous work, this project should enable him to show how female egg-laying behavior influences male behavior and how, in turn, male- female interactions influence the process of location and use of important resources.

瓦格博士的研究有三个相关的目标。虽然这项工作的重点是一种昆虫，它有更广泛的相关性的问题，栖息地和女性的行为如何相互作用，以及它们如何反过来影响男性的行为，它有助于在野外条件下的实验测试的假设的一般方法。Waage博士的第一个目标是继续开发方法来测试在野外条件下行为原因的假设。 这一点很重要，因为许多物种不能在圈养条件下饲养， 在简化的实验室条件下进行的实验往往不能揭示出大自然中发生的事情。 Waage博士选择豆娘作为研究动物，是因为他熟悉豆娘的生物学特性，以及他操纵个体及其栖息地的能力。 例如，他的研究将涉及创造，移除和改变 产卵（产卵）的网站，以测试他们或他们的特点， 地点对于这些地点的选择很重要。 确定是什么影响了雌性选择产卵地点 和雄性斑斑美蝶--这是瓦格博士的第二个发现 目标. 产卵地（溪流中的植被）是 两性的个体。 雌性用它们作为产卵的地方，雄性保护它们，并用它们作为与雌性相遇的地方。 Waage博士将调查产卵地点和周围植被的特征使它们对雄性和雌性具有吸引力。 他还将研究为什么男性和女性在使用网站时会有如此多的时间和空间变化。 回答了C.斑点实际上可能有助于解释男性和女性的许多行为， 两性之间的互动 虽然这项工作是在一个 物种，研究结果将有助于信息的一般机构 昆虫是如何寻找和利用资源的 这个项目的第三个目标是测试一些一般的想法，目前在行为生态学文献。 像大多数快速发展的学科一样，行为生态学的理论远远领先于其 试验. Waage博士将重点关注女性行为（对于 例如，它们在哪里产卵）可能是雄性行为的基础或决定因素（例如，雄性选择寻找雌性的地方， 男性之间为进入这些场所而进行的竞争）。 行为生态学 长期以来一直偏向于从男性的角度来解释事物。 这些豆娘似乎是探索雄性和雌性行为之间关系的理想动物。 与Waage博士之前的工作一起，该项目应使他能够展示雌性产卵行为如何影响雄性行为，以及雄性与雌性的互动如何反过来影响定位和使用的过程 重要资源。
