The impact of calcium decline on population growth rates of crustacean zooplankton in Canadian Shield lakes


Shakira S. E. Azan, Shelley E. Arnott

Within the last decade, calcium decline has emerged as a stressor for many soft water lakes. A legacy of long-term acid deposition and logging, calcium decline has been implicated in the loss of large herbivores, such as  216 more words


Save the plankton!

Save the whales? Sure. Save the turtles? Ditto. But if we don’t save the plankton, all ocean species will be  history. Both zooplankton (tiny animals) and phytoplankton (tiny plants) are at the base of the food chain. 249 more words

Early life stages of Northern shrimp (Pandalus borealis) are sensitive to fish feed containing the anti-parasitic drug diflubenzuron


• Diflubenzuron is used in salmon aquaculture to remove parasitic lice. • Salmon feed containing diflubenzuron increased mortality of shrimp larvae. • Additive effects of diflubenzuron and ocean acidification/warming on mortality. 299 more words
