In this seminar, PhD Candidate Monica Esmond from Griffith University will discuss her research on the value of integrating ecological indicators (using environmental DNA) into hydrogeological studies.  Her research focuses on natural springs and their connected surface and groundwater in Queensland's Great Artesian Basin, particularly the Surat Basin. This area is important for cultural, ecological, and economic reasons. The study analyzes water from springs, surface, and groundwater using a combination of environmental tracers (like isotopes and water chemistry) and eDNA. The goal is to see if this mix of biological and non-biological data can offer new understanding of water processes and quality. The research includes fieldwork at both an untouched site and one affected by human activities like farming and resource development. This study will help evaluate whether this approach can be used for environmental assessments and monitoring water resources.
