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
In 2012, for maybe the first time, Lake Superior got scummy.
Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.
It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms.
But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae.
Not the usual suspects
The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.Read More
