ARTICLES Stimulus Material for depth studies, courtesy of Macquarie University (continued) Monitoring whale health by using drones to collect their blow Macquarie University (Biological Sciences) researchers have led the design and construction of a new system to sample whale microbiota—the combination of natural bacterial colonies that live in an organism—by flying over and collecting exhaled vapours from their blowholes. The system can be fitted to a custom-built, waterproof drone to monitor the health of whales in a non-invasive manner. “In conjunction with drone experts, we have developed a low-cost system which incorporates a sterile petri dish with a remotely operated and novel ‘flip lid’,” says lead researcher Vanessa Pirotta. “This can be attached to a drone along with a GoPro camera to sample whale blow with minimal disturbance to the whales. “This system allows us to collect samples safely and reliably, by minimising external contamination such as air and seawater from outside the blowhole.” Find out more Syllabus links: Biology Module 4 – Ecosystem dynamics Inquiry question: What effect can one species have on the other species in a community?
