Almost all of the parental care behaviors and mating systems seen in the Cichlidae, a family noted for its diversity in these characters, are present in the subfamily Geophaginae. Sequences of two mitochondrial genes (cytochrome oxidase II and one other) will be determined for geophagine species and outgroup representatives, and used to derive a phylogeny. With the phylogeny, the following questions will be addressed: 1) In what sequence do the varied parental care behaviors evolve and how evolutionarily labile are they? 2) Do particular modes of parental care precede particular mating systems or vice-versa? 3) Do novel behavioral traits always precede the evolution of related morphological characters? 4) How does the area cladogram for geophagines compare to those of other neotropical fish groups? 5) How general among cichlids is the accelerated rate of cytochrome oxidase II gene evolution seen in Geophagus steindachneri? With this single phylogeny, questions of great interest will be answered to those working in such diverse fields as behavioral ecology, molecular and morphological evolution, fish systematics, and neotropical biogeograhy.

几乎所有的父母照顾行为和交配系统 在慈鲷科，一个家庭指出，其多样性，在这些 特征，存在于Geophaginae亚科。 序列 两个线粒体基因（细胞色素氧化酶II和另一个） 将确定食土动物物种和外群 代表，并用于派生一个继承人。 与 本报告将讨论以下问题：1）在 不同的父母照顾行为的演变顺序是什么， 它们在进化上有多不稳定？2)做特定模式的 父母的照顾先于特定的交配系统还是相反 3)新的行为特征总是先于 相关的形态特征？ 4)区域进化树是如何 与其他新热带鱼类相比， 群组？5)在慈鲷科鱼类中， Geophagus中细胞色素氧化酶II基因的进化 steindachneri？ 有了这个单一的遗传学， 在这些不同领域工作的人将对此感兴趣 行为生态学，分子和形态进化， 鱼类系统学和新热带生物地理学。
