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.Read More
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.Read More
Thousands of lakes in the northeastern United States are at risk of chloride contamination.
In a 17-state area from Minnesota to Missouri to Maine, elevated chloride levels in some of the region’s nearly 50,000 lakes are driven largely by landscape features that are cleared of snow and ice by road salt in the winter.
“The biggest driver of increasing chloride concentrations in these lakes was road density and development. The more developed a watershed, the more likely you are to have roads and parking lots,” said Hilary Dugan, an assistant professor in the Center for Limnology at University of Wisconsin—Madison.
Dugan is the lead author on a study examining the issue recently published in Environmental Science and Technology .Read More
