(University of Freiburg) Biologists discover a mechanism in mosses that was crucial for the evolution of ecosystems on land. www.eurekalert.org/pub_rele...
93 Researchers develop equation that helps to explain plant growth

(University of California - Los Angeles) New UCLA biology breakthrough has important implications for plants as they adapt to a warming environment. www.eurekalert.org/pub_rele...
89 Diving with the sharks

(University of California - Santa Barbara) A new study finds that humans can interact with sharks without long-term behavioral impacts for the ocean's top predators. www.eurekalert.org/pub_rele...
87 Gardening worms and climate change undermine natural coastal protection
135960 web
(NIOZ Royal Netherlands Institute for Sea Research) Dikes could be lower if they are protected against the waves by grassy marshes. But the protective salt marsh grass is struggling, not only due to increasingly stronger waves, but also to the superfood diet of ragworms. These sophisticated gardeners turn inedible, tough grass seeds into succulent, nutritious sprouts in their burrows. These cultivation techniques prevent many seeds from growing into salt marsh vegetation, thus undermin... www.eurekalert.org/pub_rele...
85 World's oldest plant-like fossils discovered
134935 web
(PLOS) Scientists at the Swedish Museum of Natural History have found fossils of 1.6 billion-year-old probable red algae. The spectacular finds, publishing on March 14 in the open-access journal PLOS Biology, indicate that advanced multicellular life evolved much earlier than previously thought. www.eurekalert.org/pub_rele...
81 Scientists follow seeds to solve ecological puzzle
136173 web
(Washington University in St. Louis) A four-year study of one rare and one common lupine growing in coastal dunes showed that a native mouse steals most of the rare lupines seeds while they are still attached to the plant. The mouse is a 'subsidized species,' given cover for nocturnal forays by European beachgrass, originally planted to stabilize the dunes. www.eurekalert.org/pub_rele...
81 Scientists discover hydrothermal vents on deep ocean voyage
135580 web
(University of Wyoming) Barbara John and her husband, Michael Cheadle, both UW professors of geology and geophysics, recently co-led a research expedition aboard the US Research Vessel Atlantis. With the aid of two small submarines tasked with exploring and sampling the sea floor, the group located five new hydrothermal vents, as well as two others that were last seen 23 years ago, at Pito Seamount in the Pacific Ocean. www.eurekalert.org/pub_rele...
76 Stanford scientists reveal how grass developed a better way to breathe
135855 web
(Stanford University) Grasses are better able to withstand drought or high temperatures than many other plants in large part due to changes in their pores, called stomata. Stanford scientists have discovered how grasses produce these altered pores, which could someday lead to crops that can better survive climate change. www.eurekalert.org/pub_rele...
75 Current jellyfish sting recommendations can worsen stings
135932 web
(University of Hawaii at Manoa) Researchers at the University of Hawai'i - Mānoa (UHM) investigated whether commonly recommended first aid actions such as rinsing with seawater or scraping away tentacles lessen the severity of stings from two dangerous box jellyfish species. Their results, published this week in the journal Toxins, reveal that some of the most commonly recommended practices actually worsen stings. www.eurekalert.org/pub_rele...
72 Study IDs link between sugar signaling and regulation of oil production in plants
135901 web
(DOE/Brookhaven National Laboratory) Scientists from Brookhaven Lab have identified a previously unknown link between a protein that maintains plant sugar balance and one that turns on oil production. The biochemical detective work points to new strategies for tapping into the energy plants capture from the sun to produce oil-based biofuels and other biomaterials. www.eurekalert.org/pub_rele...
