9224910 Sakaluk This award supports Professor Scott Sakaluk of Illinois State University to collaborate in behavioral ecology research with Professor Josef K. Mueller of the Institute of Zoology, Albert Ludwigs University, Freiburg, Germany. The objective of their research is to test various hypotheses about the reproductive strategies and parental behavior of male "burying beetles" (Nicrophorus vespilloides). They will carry out field experiments manipulating various factors that influence reproductive behavior in order to test the effect of male assistance on brood success. Paternal care is rare in insects, and the factors favoring its evolution remain unclear. Burying beetles are one of only a few arthropod taxa exhibiting biparental care, in which both parents obtain food for the developing young. There are several hypotheses to explain the continued presence of the male; however, field studies to examine the effects of the male's presence on the number of surviving young have not been done. This research will test two competing hypotheses (paternal care and mating effort) and attempt to improve understanding of this area of insect behavior. ***

9224910 Sakaluk 该奖项支持伊利诺伊州立大学的 Scott Sakaluk 教授与德国弗莱堡阿尔伯特路德维希大学动物研究所的 Josef K. Mueller 教授合作进行行为生态学研究。 他们研究的目的是测试有关雄性“埋葬甲虫”（Nicrophorus vespilloides）的繁殖策略和亲代行为的各种假设。 他们将进行现场实验，操纵影响繁殖行为的各种因素，以测试雄性辅助对育雏成功的影响。 昆虫的父系照顾很少见，有利于其进化的因素仍不清楚。 埋葬甲虫是少数表现出双亲照顾的节肢动物类群之一，父母双方都为发育中的幼虫获取食物。 有几种假设可以解释雄性的持续存在；然而，尚未进行实地研究来检验雄性的存在对存活幼崽数量的影响。 这项研究将测试两个相互竞争的假设（父亲照顾和交配努力），并试图增进对昆虫行为这一领域的理解。 ***
