4 Credit Hours May 25 – June 5, 2026 Instructors: Kenneth H. Kozak, Ph.D. (University of Minnesota) & Joseph H. K. Pechmann, Ph.D. (Western Carolina University) The Southern Appalachians are home to one of the richest and most ecologically significant salamander assemblages on Earth. This immersive field- and lab-based course introduces students to the extraordinary diversity, biology, and evolutionary history of these remarkable amphibians. Through a blend of lectures, guided discussions, hands-on laboratory work, and targeted field excursions across multiple Appalachian mountain ranges, students will explore foundational and advanced concepts in evolutionary biology and ecology. Topics include reconstructing evolutionary histories, species concepts and delimitation, life-history variation, population and community dynamics, and the role of salamanders in forest ecosystems. Readings from primary literature will deepen understanding of current research and methodologies. Students will gain experience identifying regional taxa, conducting field and laboratory analyses, and interpreting evolutionary and ecological data—while engaging directly with the landscapes that make the Southern Appalachians a global hotspot for salamander diversity. Prerequisites: Introductory biology, ecology, or evolution, or permission of the instructors.

2 Credit Hours June 1–5, 2026 Instructors: Dr. Joey Shaw, UT-Chattanooga True sedges are famously challenging to identify. With numerous species often growing side by side in the same microhabitats, reduced and specialized floral structures, unique terminology, and diagnostic features that may rely on very small measurements—or even mature material—students of botany can easily feel overwhelmed. It is no surprise that sedges are among the plant groups learners struggle with most. This course focuses on two primary goals: Building fluency in sedge terminology and learning how to confidently apply and interpret that terminology when using identification keys. Understanding the key characteristics that distinguish the many taxonomic sections of the genus Carex—the largest and most complex sedge genus—as well as how to separate Carex from other spring-flowering sedges. Using herbarium specimens, newly collected material, and additional plant samples provided in class, we will assemble an in-room reference collection organized by genus and Carex section. This hands-on approach allows students to compare specimens directly, reinforcing both visual recognition and taxonomic concepts. This workshop is designed to strengthen identification skills and build confidence in working with this large and intricate group of plants. For most participants, our focus will remain at the level of distinguishing Carex sections rather than resolving species-level identifications—though students wishing to work at the species level are welcome and encouraged to do so!
