Scientists have measured the nutritional value of herbivore dinosaurs' diet by growing their food in atmospheric conditions similar to those found roughly 150 million years ago.
Strawberries and tomatoes are among the most widely consumed fruits and vegetables worldwide. However, many people are allergic to them, especially if they have been diagnosed with birch pollen allergy. A team from the Technical University of Munich has investigated which strawberry or tomato varieties contain fewer allergens than others and to what extent cultivation or preparation methods are involved.
Researchers have calculated the capacity of North American forests to sequester carbon in a detailed analysis that for the first time integrates natural processes and climate changes that are likely to alter growth over the next 60 years.
New research from scientists at Point Blue Conservation Science and The Nature Conservancy shows how financial incentive programs can create vital habitat for waterbirds, filling a critical need in drought years. Researchers used satellite images to evaluate two issues: 1) the impact of the 2013-2015 drought on waterbird habitat in the Central Valley; and, 2) the amount of habitat created by incentive programs.
The genome of the algae species Chara braunii has been decoded. It already contains the first genetic characteristics that enabled the water plants' evolutionary transition to land.
University of Guelph researchers have discovered unsuitable soil at higher altitudes may be halting the advancement of treelines. This finding dispells the commonly held assumption that climate change is enabling trees to move farther uphill and northward. The researchers looked at plant growth at higher altitudes in the Canadian Rockies, grew spruce and fir seedlings at varying elevations and collected soil samples from the same areas to grow spruce seeds in growth chambers .
An international team, which included three University of Maryland researchers, sequenced and analyzed the genome of Chara braunii, a freshwater green alga closely related to land plants. By comparing Chara's genome to multiple land plant genomes, the team was able to identify many important genes that originated in a common ancestor shared by Chara and land plants.
University of Kansas scientists discovered that polyps have no qualms about treating a nonrelated individual like part of the family. This goes way beyond sharing meals or even a roof. Polyps of the marine hydrozoan Ectopleura larynx allow nonrelated individuals to fuse their bodies to the familial colony and share what is essentially skin and a stomach. The findings appeared yesterday in the journal Evolution Letters.
Invasive plants have the ability to adapt to new environments -- and even behave like a native species, according to University of Stirling research.
Biologists at the Ruhr-Universität Bochum characterized new, unknown photoreceptors from the bioluminescent flashlight fish Anomalops katoptron. The photoreceptors known as opsins allow the fish to detect light with a specific wavelength. As published on the July 11, 2018, in PLOS ONE the scientists found new opsin variants, which are specialized to detect low intensity blue light in the wavelength range of bioluminescent light emitted by the fish. The blue light can be used to influence the fish behavior.
