A new study led by researchers at the University of Wisconsin-Madison examined why private-land conservation data is sometimes inaccessible and found that limited capacity within some federal agencies as well as laws prohibiting others from disclosing certain information are to blame.
New research from a multi-university team of biologists shows what could be a startling drop in the amount of carbon stored in the Sierra Nevada mountains due to projected climate change and wildfire events.
A team of researchers, led by a UC Riverside plant cell biologist, has for the first time identified a small RNA species and its target gene that together regulate female germline formation in plants -- crucial knowledge for manipulating plant reproduction in order to improve agriculture. The new work not only identifies a regulatory module for an important developmental process, it also implies that there is likely cell-to-cell communications via RNA or protein in this process.
Spanish ecologists have observed an unusual way in which treetop-grazing goats may be benefiting the trees: the goats spit out the trees' seeds. Miguel Delibes, Irene Castañeda, and José M Fedriani reported their discovery in the latest Natural History Note in the May issue of the Ecological Society of America's journal Frontiers in Ecology and the Environment.
Salk researchers identify genetic variants that help plants grow in low-iron environments, which could improve crop yields.
A new study looks at how three varieties of camelina perform when grown in two different regions within the Great Plains. The end goal is to find the camelina variety that performs best in each location or environment -- beyond the genetics involved.
Edible dormice feed preferably on high-energy seeds for reproduction and putting on fat reserves. Beech trees, however, save energy by producing seeds only in certain years on a large scale. A long-term study by researchers from Vetmeduni Vienna has shown for the first time that edible dormice avoid areas with a high beech density. They prefer areas with a mix of conifers and beech trees and thus a balanced food supply.
In summer 2010, Los Angeles was losing about 100 gallons of water per person per day to the atmosphere through the evaporation and plant uptake of lawns and trees. Lawns accounted for 70 percent of the water loss, while trees accounted for 30 percent, according to a University of Utah study published in Water Resources Research.
Today in Nature Communications, researchers from BTI and the Shanghai Normal University report a new draft genome of Spinacia oleracea, better known as spinach. Additionally, the authors have sequenced the transcriptomes (all the RNA) of 120 cultivated and wild spinach plants, which has allowed them to identify which genetic changes have occurred due to domestication.
Researchers have figured out how a once-defeated bacterium has re-emerged to infect cotton in a battle that could sour much of the Texas and US crop. And it boils down to this: A smart bacteria with a sweet tooth.
