Synergistic Impacts of Co‐Exposure to Microplastics and Vibrio harveyi on the Immune and Stress Responses of the Big‐Belly Seahorse Hippocampus abdominalis

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
Synergistic effects of microplastic and Vibrio harveyi co‐exposure on big‐belly seahorse (Hippocampus abdominalis). Seahorses were exposed to microplastics (50 beads/L of 0.2 μm SMP and 1.0 μm LMP) and injected with V. harveyi (1 × 103 CFU/mL).

Dam It, I’m Stranded: Evaluating Fish Stranding Downstream of Two Hydropeaking Dams in Northern Ontario

River Research and Applications, EarlyView.
ABSTRACT Globally, there has been an increase in the development and use of hydropower to produce energy. Hydropeaking is an operating regime that is used to meet real‐time energy demands; however, daily fluctuations in flows may result in fish becoming stranded.
