Bacteria found in muddy marshes, estuaries and coastal sediment synthesise one of the Earth's most abundant climate cooling gases -- according to new research from the University of East Anglia (UEA). Dimethylsulfoniopropionate (DMSP) is an important nutrient in marine environments with billions of tonnes produced annually by marine phytoplankton (microscopic plant-like cells), seaweed, corals and bacteria.
The molecular mechanism used by many bacteria to kill neighboring cells has redundancy built into its genetic makeup, which could allow for the mechanism to be expressed in different environments.
Freshwater wetlands from Georgia to New York are home to a previously unrecognized species of medicinal leech, according to scientists at the Smithsonian's National Museum of National History. The new species was first identified from specimens collected in southern Maryland less than 50 miles from Washington, D.C., prompting a search through marshes and museum collections that revealed that the leech has long occupied a range that stretches throughout the eastern United States.
An unprecedented survey has revealed the loss of about 85 percent of historical tidal wetlands in California, Oregon, and Washington. The report, published today in PLOS ONE, also highlights forgotten estuary acreage that might now be targeted for restoration.
A higher standard of wastewater treatment in the UK has been linked to substantial improvements in a river's biodiversity over the past 30 years. The Centre for Ecology & Hydrology analysed data from the regular monitoring of both chemicals and invertebrates in the River Ray in Wiltshire -- downstream from Swindon's large wastewater treatment plant - between 1977 and 2016.
Evolutionary biologists from Konstanz analyze the role of microRNAs in the evolution of new species.
Research conducted at the University of Hawai'i (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST) on a marine sponge in Kāneʻohe Bay, Oahu revealed a unique feeding strategy, wherein the sponge animal acquires important components of its diet from symbiotic bacteria living within the sponge.
A new study is the first to demonstrate that schooling in fishes can be facilitated by bioluminescent flashes in the absence of ambient light. Led by researchers at the American Museum of Natural History, the research raises the possibility that fish schooling may occur in the deep sea, where it was previously assumed to be too dark for fish to coordinate their movements with each other. The study is published today in the journal PLOS ONE.
A fisherman's curiosity led to identification of the correlation between microbial communities in recreational freshwater locales and seasonal environmental changes, according to a team of researchers from Penn State.
Contrary to what was widely communicated in media by high-profile figures, the movie 'Finding Dory' had no impact on increasing demand for blue tang fish, the species of the main protagonist. There was, however, an increase in online searches for that species, showing that blockbusters can drive information-seeking behavior about nature.
