Researchers at the University of New Hampshire are turning to an unusual source -- otoliths, the inner ear bones of fish -- to identify the nursery grounds of winter flounder, the protected estuaries where the potato chip-sized juveniles grow to adolescence. The research, recently published in the journal Transactions of the American Fisheries Society, could aid the effort to restore plummeting winter flounder populations along the East Coast of the US.
The yields of many important crops in Europe have been stagnating since the 1990s. As a result, the input of organic matter into the soil -- the crucial source for humus formation -- is decreasing. Scientists from the Technical University Munich suspect that the humus stocks of arable soils are declining due to the influence of climate change. Humus, however, is a key factor for soil functionality, which is why this development poses a threat to agricultural production -- and, moreover, in a worldwide context.
A study by the University of Liverpool has found that the genetic diversity of wild plant species could be altered rapidly by anthropogenic climate change.
Thanks to seven years of work done at the RIKEN Quantitative Biology Center and Hiroshima University, scientists can take a peek into a single plant cell and -- within minutes -- get a view of the small molecules, including metabolites, hormones, nutrients and lipids, inside it.
Researchers reporting in the Cell Press journal Current Biology on Aug. 27 have evidence in support of a clearly defined depth limit for deep-sea fishing in Europe. The findings come just as the European Union considers controversial new legislation to manage deep-sea fisheries, including a ban on trawling below 600 meters.
After hours harvesting forage, managing livestock and milking cows, new Cornell University agricultural economic research shows family members who work on the family dairy farm make $22,000 less annually than comparable hired managers, but are handsomely compensated with 'socioemotional' wealth.
The Pacific Northwest is abundantly dotted with wildfires in Washington, Oregon, Idaho and Montana.
Granada, Spain's climate and layout is like that of many cities in the Mediterranean area, which has the highest occurrence of pollen allergies in the world. The researchers hope their efforts will lead to fantastic urban green spaces that don't cause allergic reactions for 30 percent of the city's population.
New cost-effective material which mimics natural 'extracellular matrix' has allowed scientists to capture previously unseen behaviour in individual plant cells, including new shapes and interactions. New methods highlight potential developments for plant tissue engineering.
Using DNA sequencing, researchers have accurately painted a clear picture of fish spawning activities in a marine protected area and have created a baseline for continuing studies on the effects of climate variability on fish populations. Scripps Institution of Oceanography at UC San Diego researchers collected 260 samples off the Ellen Browning Scripps Memorial Pier over a two-year period and used DNA barcoding to accurately identify over 13,000 fish eggs.
