The effects of environmental stressors on aquatic invertebrate behaviour and metabolism

Naima.JPG

I am focusing on ambient temperatures effects on metabolism, body size and movement (speed and tortuosity) of aquatic invertebrates, namely Gammarus pulex, Niphragus kochianus and Niphragus fontanus

​

Specifically, I am measuring the oxygen consumption and activity levels of these species at the individual level, as proxies of possible sub-optimal reactions to temperature ranging from 4 to 33°C. I am employing vial-based oxygen sensor equipment in combination with controlled temperature rooms, Raspberry Pi cameras, and automated tracking hardware with customised software.
