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
Researchers in England devised a new method for monitoring biodiversity with an insect soup and low cost DNA sequencing, according to a University of East Anglia press release.
Douglas Yu, a biology professor and the lead researcher for the study, said analyzing a few hundred ground-up bugs gives researchers equivalent data to traditional intensive methods for a fraction of the cost.
He said, compared to high quality data sets analyzing 55,000 arthropods and birds, sequencing bug juice was just as effective.
The researchers use a process called metabarcoding to identify bugs and biodiversity of an environment.
The measurement could eventually be established as a low cost, low impact way to understand the biodiversity of a system through some of its smallest creatures.Read More
Some of the most interesting data in the world of river and stream monitoring come at times when it's practically impossible to capture—during extreme weather events, for example. Timing alone makes capturing unusual events a challenge, and these kinds of issues have prompted researchers to use classic monitoring data along with new technologies to develop and improve hydraulic modeling for estimating river flows.
Steven Lyon , a Conservation Scientist with The Nature Conservancy, Professor at Stockholm University and Associate Professor at The Ohio State University, spoke with EM about the research .Read More
