(NOAA Fisheries West Coast Region) An ecological pileup of unprecedented changes in the ocean off the West Coast beginning about 2014 led to record entanglements of humpback and other whales, putting the region’s most valuable commercial fishery at risk, new research shows.
(University of California – Santa Cruz) Climate change is increasing the frequency and severity of marine heat waves — warm water anomalies that disrupt marine ecosystems — and this is creating new challenges for fisheries management and ocean conservation. A new study shows how the record-breaking marine heat wave of 2014 to 2016 caused changes along the US West Coast that led to an unprecedented spike in the numbers of whales that became entangled in fishing gear.
Scientists have uncovered a broad diversity of large and giant viruses that belong to the nucleocytoplasmic large DNA viruses (NCLDV) supergroup. As a result, virus diversity in this group expanded 10-fold from just 205 genomes, redefining the phylogenetic tree of giant viruses.
In recent years, astronomers have pondered the search for biosignatures, or signs of life, in the atmospheres of distant exoplanets. Will the James Webb Space Telescope – due to launch in 2021 – be able to detect them? A new technique says yes.
(Forschungsverbund Berlin) Cyanobacteria, also known as blue-green algae, are among the most common organisms on Earth. A research team led by the Leibniz-Institute of Freshwater Ecology and Inland Fisheries and Heidelberg University has now shown for the first time that Cyanobacteria produce relevant amounts of methane in oceans, inland waters and on land. Due to climate change, “Cyanobacteria blooms” increase in frequency and extent, amplifying the release of methane from inland waters and oceans to the atmosphere.
Each year, 25 million tons of seaweed is harvested, most of which is in Asia and used for human consumption and cosmetics. But what about using it to power our vehicles? Danish scientists recently announced they have used a seaweed fuel to power an automobile, achieving speeds of 50 mph (80 kph), using a biofuel […]
(Ludwig-Maximilians-Universität München) A new study published by biologists at Ludwig-Maximilians-Universitaet (LMU) in Munich demonstrates that there are no simple or universal solutions to the problem of engineering plants to enable them to cope with the challenges posed by climate change.
(Penn State) Selective fishing can disrupt the delicate balance maintained between corals and algae in embattled Caribbean coral reefs.
