To determine whale pregnancy, researchers have relied on visual cues or hormone tests of blubber collected via darts, but the results were often inconclusive. Research from the National Institute of Standards and Technology (NIST) points to a weakness of previous testing and evaluation methods and provides a new hormone testing regime that offers better results.
The structure of vegetation and steam distance are important factors to consider in order to protect the biodiversity of forest arthropods, as stated in an article now published in the journal Forest Ecology and Management. The conclusions of the study note the farther we are from a river course, the better conditions for the communities of arthropods in the forests, since they need a cool and wet microclimate.
With some reports predicting the precision agriculture market will reach $12.9 billion by 2027, there is an increasing need to develop sophisticated data-analysis solutions that can guide management decisions in real time. A new study from an interdisciplinary research group at University of Illinois offers a promising approach to efficiently and accurately process precision ag data.
New work shows how using next-generation DNA sequencing on ancient packrat middens--nests made out of plant material, fragments of insects, bones, fecal matter, and urine--could provide ecological snapshots of Earth's past. Published today in the journal Ecology and Evolution, the study may pave the way for scientists to better understand how plant communities--and possibly animals, bacteria, and fungi as well--will respond to human-caused climate change.
The University of Hawaii at Manoa research team analyzed observer records of individual fishing events, logbook summary reports and detailed satellite data on vessel movements.
Otago scientists studying sperm whales off the coast of Kaik?ura have discovered earthquakes affect their ability to find food for at least a year. The University of Otago-led research is the first to examine the impact of a large earthquake on a population of marine mammals, and offers new insight into how top predators such as sperm whales react and adapt to a large-scale natural disturbance.
Montmorency tart cherry juice has gained a reputation as a recovery drink among elite and recreational exercisers, with research suggesting benefits for reducing strength loss and improving muscle recovery after intensive exercise. Now, a new first-of-its-kind analysis published in the Journal of the American College of Nutrition found that tart cherries improved endurance exercise performance among study participants.
Fresh produce is a major vehicle for noroviruses, a group of viruses that are the most common cause of gastroenteritis in developed countries. However, the viruses are quite resistant to cold pasteurization treatments such as irradiation, which are used to destroy bacteria, moulds, parasites, and insects. The irradiation process uses gamma rays or X-rays to destroy these viruses but at the dose needed to eliminate them, it can affect the physicochemical properties of fresh produce.
A secret to survival amid rising global temperatures could be dwelling in the tidepools of the US West Coast. Findings by University of California, Irvine biologists studying the genome of an unusual fish residing in those waters offer new possibilities for humans to obtain dietary protein as climate change imperils traditional sources. Their paper appears in Proceedings of the Royal Society B.
Perennial grasses can be converted into everything from ethanol to bioplastics, but it's unclear which bioproducts hold the greatest potential. BioSTEAM, a new open-source simulation software package in Python developed by researchers at the University of Illinois at Urbana-Champaign, gives scientists, engineers, biotechnology companies, and funding agencies a fast, flexible tool to analyze the economics of producing different biofuels and bioproducts -- in a matter of seconds.
