COUPLING A PURPOSE BUILT IMAGING SYSTEM WITH COMPUTER VISION TO ESTIMATE INVERTEBRATE DRIFT WITHIN LOTIC ECOSYSTEMS
Imaging systems are becoming more common place for monitoring target organisms in diverse ecosystems. Yet the integration of imaging lotic ecosystems has not gained the same traction as in terrestrial, lentic, or marine environments due to the challenges and costs associated with deploying traditional sampling methods. The methodology for deploying imaging systems within lentic and marine ecosystems cannot be utilized within lotic ecosystems due to these environments being characterized by unidirectional flow. Constant barrage from abrasive flow material requires a strong housing to protect the specialized lens, camera, and lighting configuration from harsh environments with variable physical conditions. These unique conditions required the development of a purpose specific imaging system that can be utilized within lotic ecosystem. Recent advances in next generation imaging systems, together with open-source software, provide a way to identify and enumerate stream invertebrates in drift that can greater reduce the time and costs associated with sampling this process manually. I present here a study that employs a prototype, purpose-built, imaging system to address the challenges associated with accurately sampling invertebrate drift within lotic ecosystems along California’s redwood coast.
