比约恩·施密特博士.D.

助理教授

在北佛罗里达长大的盖茨博士. 比约恩·施密特的童年是在探索溪流和大自然中度过的. 他对鱼类研究的兴趣是在他的本科工作之后增长的. 施密特 has been hooked on fish ecology since catching a paddlefish—an amazing species to hold and observe up close—on a sampling project in the Red River of Louisiana. He is happiest when exploring the diverse species groups present in the lakes and rivers of North America and Asia.

His passion for fish conservation and understanding how humans are impacting aquatic communities drives 施密特 to investigate solutions for ecologically sound, sustainable growth in situations with complex water demands or needs.

你会对考虑a的学生说什么&移动商务?

我们是一个真正以学生为中心的组织, with smaller class sizes allowing for better interaction between faculty and students. There are many opportunities for undergraduates to get involved with research at the school, 为他们的职业生涯获得宝贵的经验. 我们的目标是A&移动商务是通过我们的使命“教育”来改变生活. 发现. 实现.” Our faculty are committed to transforming lives by sharing their passion and expertise for the subjects they research and teach, providing avenues for students to experience personal and professional growth. A&移动商务靠近达拉斯-沃斯堡大都会区, 因此, can offer an urban or rural experience that can be tailored to students' preferences and needs.

是什么吸引了你的纪律?

My favorite place is standing in the middle of a stream quietly observing the life around me. 关于流有一些特别的东西. 它们有稳定的栖息地特征, 但这些特征也每时每刻都在变化, 每一个季节，每一年. 如果你十年后再去看一条小溪, 它可能看起来与相同的栖息地特征相同, 但这些功能的具体细节可能会有所不同. 一段小溪可能仍然有水坑和水坑, but the exact placement of the riffle-pool sequence may have shifted due to the specific history of flow events in that system. I am drawn to these systems because they are both stable and dynamic, 这会导致一些有趣的人口和社区模式. Freshwater environments are also some of the most at-risk ecosystems with increasing human populations, 尤其是在像北德克萨斯这样周期性干旱的地区. My research mainly focuses on how human impacts affect aquatic populations and communities, and looks to provide insight to guide conservation management of rare species and guide sustainable growth and land use in relation to impacts on freshwater communities. My research often draws on concepts from landscape ecology and population genetics to investigate these patterns.

Tell us about a project you are currently working on or recently completed.

I recently investigated invasion and range expansion in storage lakes connected by a large-scale water diversion in Asia. Three fish species had expanded distributions in the system, driven by water diversion practices. We conducted genetic analysis on lake populations to understand and model patterns of non-native spread. An interesting result was that specific ecological differences in the species led to differing patterns of spread when colonizing new lake populations. Genetic analysis showed that two species that had buoyant eggs and longer larval stages had a cascading pattern of spread in the system, meaning downstream populations had genetic sources from all upstream points in the system. This indicated that the spread for these species was mainly caused by the movement of early life stages that could deposit or move through lakes in a cascading pattern.

The species that had comparatively reduced larval duration mainly spread in a stepwise manner, with genetic sources of new populations being the immediate upstream neighbor, which indicated a more limited larval transport or adult movement in the system. This project can allow for a better understanding of the risks involved in systems connected by water diversion that house different communities. 具体地说, this research shows how specific traits of potentially invasive species, 包括早期生活史的模式, 可以比较, which can provide guidance for water managers to avoid seasonal diversion times that would cause unintentional spread of larvae during reproductive seasons of problematic species.
