Animals use a diverse set of signals of different sensory modes ("multimodal signals") to facilitate social interactions. For instance, most birds use unique acoustic (song) and visual (colorful plumage) signals in attracting mates or defending territories. Recent studies indicate that these multimodal signals are important in distinguishing and maintaining species; however, the underlying reasons why signals are so diverse among species remain little understood. Using a combination of observational, genetic and experimental approaches, this research aims to uncover the processes that generate signal and species diversity. Populations of the chestnut-bellied flycatcher Monarcha castaneiventris show dramatic variation in song and plumage color throughout its range in the Solomon Islands. The work will test if island groups differ in forest habitat, social structure and abundances of feather-degrading bacteria, and whether this variation is linked to the observed differences in song and color among the flycatcher populations. The scientific component of this work will be linked to education and conservation by the development of a field course that will partner undergraduate students with Solomon Island biologists, and the implementation of outreach programs aimed at conserving the endangered habitats of the Solomon Islands. In sum, the research program will provide a unique understanding of the factors that shape biodiversity in nature, which will be used as a platform for conservation outreach, and to train Solomon Island biologists and undergraduate students, especially those from groups underrepresented in the biological sciences.

动物使用不同感官模式（“多模式信号”）的各种信号来促进社交互动。例如，大多数鸟类在吸引伴侣或捍卫领土时使用独特的声学（歌曲）和视觉（彩色羽毛）信号。最近的研究表明，这些多模式信号对于区分和维持物种很重要。但是，信号在物种之间如此多样化的根本原因尚不清楚。该研究结合了观察性，遗传和实验方法的结合，旨在发现产生信号和物种多样性的过程。栗子腹部捕蝇器Monarcha castaneiventris的种群在所罗门群岛的整个范围内都显示出歌曲和羽毛色的巨大变化。这项工作将测试岛屿群体在森林栖息地，社会结构和羽毛降解细菌的丰度是否有所不同，以及这种变化是否与捕蝇器种群中观察到的歌曲和色彩差异有关。这项工作的科学组成部分将通过开发现场课程的发展与教育和保护有关，该课程将与所罗门岛的生物学家合作，并实施旨在保护所罗门群岛濒危栖息地的外展计划。总而言之，该研究计划将对在自然界中塑造生物多样性的因素提供独特的理解，该因素将被用作保护外展的平台，并培训所罗门岛的生物学家和本科生，尤其是来自生物科学领域不足的群体的人。
