This collaborative International Research Experience for Students (IRES) award will support 15 U.S. undergraduate students and one graduate student, under the direction of Drs. Romi Burks from Southwestern University and Kenneth Hayes from University of Hawaii, to carry out collaborative research in Brazil and Uruguay for three years. The program is co-organized by Dr. Silvano Thiengo from the Instituto Oswaldo Cruz in Brazil and Dr. Mariana Meerhoff from the Universidad de la Republica in Uruguay. The goal of the project is to create an Ampullariidae model for a group of aquatic snails commonly called apple snails using phylogeography, laboratory integration, and field inquiry. Brazil harbors the greatest number of ampullariid species and genera and provides the largest latitudinal span (~37º) of any country in South America. Additionally, the original Guaraní, word "Uruguay" translated into Spanish as "river of the snails." Study of the phylogeny of these snails can be used to investigate important evolutionary processes, particularly those associated with major habitat transitions (e.g. marine to freshwater to terrestrial). Students' research will focus on quantifying genetic variation in this understudied group of aquatic snails, identifying patterns of speciation, investigating traits that promote invasiveness, and determining reproductive potential.This IRES award brings together a diverse community of researchers and students from the United States, Brazil, and Uruguay. In addition to working directly with the host scientists, U.S. students will blog about their international research experience and work closely with other undergraduate and graduate students from the host country. Participating students will also develop educational materials that can be used locally in their host countries. Upon return to their home institution, students will disseminate their results through professional meetings, scientific publications, and social media networks. The research also has important societal benefits as apple snails are highly invasive species and vectors of parasitic nematodes that can cause illness in mammals, including humans. Insights into how the trophic roles that these snails inhabit in native habitats may lend insight into how to deal with their presence in invaded wetland ecosystems such as the Florida Everglades.

这项合作性国际学生研究经验奖 (IRES) 将支持 15 名美国本科生和一名研究生，在西南大学的 Romi Burks 博士和夏威夷大学的 Kenneth Hayes 博士的指导下，在巴西和乌拉圭开展合作研究。该项目由巴西 Oswaldo Cruz 研究所的 Silvano Thiengo 博士和巴西共和国大学的 Mariana Meerhoff 博士共同组织，为期三年。乌拉圭该项目的目标是利用系统发育学、实验室整合和实地调查为一群水生蜗牛（通常称为苹果蜗牛）创建一个 Ampullariidae 模型。巴西拥有最多数量的 Ampullariid 物种和属，并提供最大的纬度跨度（ ~37°) 南美洲的任何国家此外，原始的瓜拉尼语“乌拉圭”翻译成西班牙语，意思是“河流的河流”。对这些蜗牛的系统发育的研究可用于调查重要的进化过程，特别是与主要栖息地转变（例如海洋到淡水到陆地）相关的进化过程。学生的研究将集中于量化这一待研究的水生群体的遗传变异。蜗牛，识别物种形成模式，调查促进入侵的特征，并确定繁殖潜力。该 IRES 奖项汇集了来自美国的不同研究人员和学生群体，除了直接与东道国科学家合作外，美国学生还将在博客上介绍他们的国际研究经验，并与东道国的其他本科生和研究生密切合作，开发可在当地使用的教育材料。返回所在国后，学生将通过专业会议、科学出版物和社交媒体网络传播他们的研究成果，因为苹果螺是高度入侵物种和寄生媒介。可能导致包括人类在内的哺乳动物患病的线虫，深入了解这些蜗牛在原生栖息地中的营养作用可能有助于了解如何应对它们在佛罗里达大沼泽地等被入侵的湿地生态系统中的存在。
