Abstract DBI 9750278 Caitlin Gabor This action funds an NSF Postdoctoral Research Fellowship in Biosciences Related to the Environment for 1997. This fellowship provides an opportunity for the Fellow to gain additional scientific training beyond the doctoral degree and to pursue innovative and imaginative into the fundamental mechanisms underlying the interactions between organisms and their environment at the molecular, cellular, organismal, population, community and/or ecosystem level in any area of biology supported by the Directorate for Biological Sciences of the National Science Foundation. Each fellowship supports a research and training plan to be carried out in a sponsoring laboratory. The research and training plan for this fellowship is entitled "Reproductive character displacement on mate selectivity in live bearing fish." Reproductive character displacement (RCD) has been proposed to play an integral role in the speciation process. Studies to date suggest that the hypothesis has value but all have been limited in one way or another. This research uses the bisexual sailfin mollie, Poecilia latipinna, and the unisexual mollie, P. formosa, a hybrid with strict maternal inheritance, to evaluate RCD on male mate selectivity for conspecific females versus gynogenetic females along a transect of allopatric and sympatric populations. Allozyme variation is being used to estimate gene flow and its relationship to the spread of the male discrimination trait.

摘要 DBI 9750278 Caitlin Gabor 这项行动为1997年国家科学基金会与环境有关的生物科学博士后研究金提供资金。 该奖学金为研究员提供了一个机会，使他们能够在博士学位之外获得额外的科学培训，并在分子，细胞，生物体，种群，在国家科学基金会生物科学理事会支持的任何生物学领域的社区和/或生态系统水平。 每项研究金资助一项研究和培训计划，该计划将在一个赞助实验室进行。 该研究金的研究和培训计划题为“活产鱼的生殖特征置换对择偶选择的影响”。“生殖特征置换（RCD）被认为在物种形成过程中起着不可或缺的作用。 迄今为止的研究表明，这一假设是有价值的，但都受到了这样或那样的限制。 本研究使用两性的帆鳍莫莉，花，和单性的莫莉，P.福尔摩沙，严格的母系遗传的杂交，以评估RCD雄性交配选择性的同种女性与雌核发育女性沿着异域和同域种群的样带。 等位酶变异被用来估计基因流及其与雄性歧视性状传播的关系。
