MSB 318: Mathematical Sciences Building, Room 318

Our [colloquium](https://sciences.ucf.edu/math/colloquium/) series offers a diverse platform for research scholars, faculty, students, and industry experts to share and exchange ideas, fostering discussion and networking across mathematics, statistics, and data science.

Professor [Suzanne Lenhart](https://web.math.utk.edu/~slenhart/) from the University of Tennessee, Knoxville, will speak at this week's colloquium on Natural System Management: Modeling Examples.

Abstract: Specific management features can be included directly into the model framework, and outcomes can suggest the need for external actions on the natural system. Models with discrete and continuous time steps, and some spatial features, will be presented. In one example, optimal control techniques to design time-varying harvest rates of anchovy stock will be illustrated in a food chain system of differential equations for the Turkish coast of the Black Sea, using landing data. In another example, we find the relationship between air temperature and emergence success of hatchlings across multiple nesting seasons to better understand the potential impact of climate change on Loggerhead sea turtle populations. We demonstrate the effect of changing hatchling emergence success on the juvenile and adult populations using a combination of a statistical model and a discrete time model (with two time scales).
