Copepod Life Cycles Shift with Marine Heatwaves: A New Ocean Indicator
Copepods are the ocean's canaries, and their response to marine heatwaves is proving more nuanced than expected. Using the Helgoland Roads time series, researchers found that blooms often contract when heatwaves strike during their peak, though most species show no consistent shift in timing beforehand. That distinction matters. It suggests selective pressure is intensifying within blooms themselves. As heatwaves grow stronger, these small disruptions could cascade through food webs, ultimately reshaping fish recruitment.

Saint John Harbour: Establishing a Baseline for Microplastic Levels
Blue and black fibres dominated every seawater sample collected in Saint John Harbour, and 94% of zooplankton taxa had ingested microlitter. That finding, from a multi-year survey by our researchers, establishes a critical baseline for microplastic levels in the Bay of Fundy. Notably, larval fish and *Calanus* copepods showed the highest encounter rates. This is empirical, local data, the kind needed to monitor change and assess ecological risk.
