This DDEP proposal seeks support for PhD candidate Stuart C. Willis for research on species formation in Brazil. Mr. Willis will be working under the guidance of both Dr. Guillermo Orti (University of Nebraska-Lincoln) and Dr. Izeni Pires Farias (Universidade Federal do Amazonas, Manaus, Brazil). The PIs have a novel perspective on species formation based on the growing recognition that hybridization, that is the process of combining different varieties or species of organisms to create a hybrid may lead to new species and thus applies to animals and not just to plants and bacteria. They plan to test their theory on species rich faunas such as the Neotropical freshwater fishes to classify and study previously unidentified hybrid species. The discovery and cataloguing of unique genetic lineages is particularly critical for setting sustainable management and conservation priorities of fishes which are considered important commercial food and recreational resources.

该 DDEP 提案寻求对博士候选人斯图尔特·C·威利斯 (Stuart C. Willis) 巴西物种形成研究的支持。 Willis 先生将在 Guillermo Orti 博士（内布拉斯加大学林肯分校）和 Izeni Pires Farias 博士（巴西马瑙斯联邦亚马逊大学）的指导下工作。 PI 对物种形成提出了新颖的观点，因为人们越来越认识到杂交（将不同品种或物种的生物体组合起来形成杂交体的过程）可能会产生新物种，因此不仅适用于植物和细菌，而且适用于动物。 他们计划在物种丰富的动物群（例如新热带淡水鱼类）上测试他们的理论，以对以前未识别的杂交物种进行分类和研究。 独特遗传谱系的发现和编目对于确定鱼类的可持续管理和保护优先事项尤其重要，鱼类被认为是重要的商业食品和娱乐资源。
