Hippo Dung Revealed As Important Food Source In African Rivers
Few studies have looked at the effects hippos have on the water quality of streams. And the reason is simple: Studying near hippos isn’t safe. 
 
“It’s an ornery animal to work with,” said Doug McCauley, assistant professor of ecology, evolution and marine biology at the University of California, Santa Barbara, who just completed a study measuring the effects of hippo dung on the ecosystem of an African river. “When you’re sampling in a stream with salmon, there’s no threat that a salmon would bite you in half.” 
 
But for studies near gigantic hippos, the threat of danger is very real.

Zooplankton drifts through the ocean, often ignored by the public in favor of more charismatic marine organisms farther up the food chain. 
 A new crowdsourced project aims to change that, giving anyone a closer look at small and intricate zooplankton. PlanktonPortal.org features 900,000 high resolution images of zooplankton and tasks the public to identify them as part of data processing for a collaborative study, based out of the University of Miami Rosenstiel School of Marine and Atmospheric Science. 
 Researchers hope the project will tell them more about zooplankton behavior, grouping and interaction.

Yellow perch are a species central to the culture and economy surrounding Lake Erie. With the largest commercial fishery and a prolific sportfishing industry, Lake Erie's yellow perch are a treasured study subject for environmental scientists. Daily bag limits and other public wildlife regulations rely heavily on the work of scientists like Ann Marie Gorman, one of the Fisheries Biologists responsible for coordinating ODNR ’s Central Basin Bottom Trawl Survey. 
 
 The survey, ongoing since 1990, conducts seasonal assessments of the bottom fish community in Erie. It aims to index annual recruitment and catch-at-age of yellow perch.
