Published Tech could help BC farmers reach customers, mitigate climate change impacts
(via sciencedaily.com) Technology exists that the BC government could leverage to help small farmers connect directly with consumers and also mitigate climate change impacts, say new findings.
Published Climate change alters a human-raptor relationship
(via sciencedaily.com) Bald Eagles and dairy farmers exist in a mutually beneficial relationship in parts of northwestern Washington State. According to a new study, this 'win-win' relationship has been a more recent development, driven by the impact of climate change on eagles' traditional winter diet of salmon carcasses, as well as by increased eagle abundance following decades of conservation efforts.
Published Swan populations grow 30 times faster in nature reserves
(via sciencedaily.com) Populations of whooper swans grow 30 times faster inside nature reserves, new research shows.
Published Researchers find decaying biomass in Arctic rivers fuels more carbon export than previously thought
(via sciencedaily.com) A new study found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That's a significantly greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.
Published Study shows how biodiversity of coral reefs around the world changes with depth
(via sciencedaily.com) Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.
Published Minke whales are as small as a lunge-feeding baleen whale can be
(via sciencedaily.com) A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.
Published Arctic climate modelling too conservative
(via sciencedaily.com) Climate models used by the UN's IPCC and others to project climate change are not accurately reflecting what the Arctic's future will be, experts say.
Published Remarkable squirting mussels captured on film
(via sciencedaily.com) Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.
Published Existential threats to the iconic Nile River Delta
(via sciencedaily.com) Decades of poor environmental and water management turned the Nile River Delta from a unique ecological habitat in the Sahara to one of the largest polluted areas on the planet, with tens of millions of people and migrating birds at risk of exposure to water-borne contaminants.
Published Assessing the potential risks of ocean-based climate intervention technologies on deep-sea ecosystems
(via sciencedaily.com) An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.
Published Sea temperatures control the distributions of European marine fish
(via sciencedaily.com) An analysis extending from southern Portugal to northern Norway highlights the importance of temperature in determining where fish species are found.
Published Standard model of electroporation refuted
(via sciencedaily.com) Strong electric fields can be used to create pores in biomembranes. The method is known as electroporation. Inducing such defects in membranes in a targeted manner is an important technique in medicine and biotechnology, but also in the treatment of foodstuffs.
Published The world's atmospheric rivers now have an intensity ranking like hurricanes
(via sciencedaily.com) Atmospheric rivers, which are long, narrow bands of water vapor, are becoming more intense and frequent with climate change. A new study demonstrates that a recently developed scale for atmospheric river intensity (akin to the hurricane scale) can be used to rank atmospheric rivers and identify hotspots of the most intense atmospheric rivers not only along the U.S. West Coast but also worldwide.
Published Life in the smoke of underwater volcanoes
(via sciencedaily.com) Disconnected from the energy of the sun, the permanently ice-covered Arctic deep sea receives miniscule amounts of organic matter that sustains life. Bacteria which can harvest the energy released from submarine hydrothermal sources could thus have an advantage. Scientists found bacteria uniquely adapted to this geo-energy floating in deep-sea waters. They describe the role of these bacteria for biogeochemical cycling in the ocean.
Published How climate change threatens Asia's water tower
(via sciencedaily.com) Original source Tibet is known as the 'Water Tower of Asia,' providing water to about 2 billion people and supporting critical ecosystems in High Mountain Asia and the Tibetan Plateau, where many of the largest Asian river systems originate. This region is also one of the areas most vulnerable to the compounding effects of climate change and human activities. Researchers are identifying policy changes that need to happen now to prepare for the future impacts projected by climate models.
Published A pool at Yellowstone is a thumping thermometer
(via sciencedaily.com) Doublet Pool's regular thumping is more than just an interesting tourist attraction. A new study shows that the interval between episodes of thumping reflects the amount of energy heating the pool at the bottom, as well as in indication of how much heat is being lost through the surface. Doublet Pool, the authors found, is Yellowstone's thumping thermometer.
Published Unprecedented increase in ocean plastic since 2005 revealed by four decades of global analysis
(via sciencedaily.com) A global dataset of ocean plastic pollution between 1979 and 2019 reveals a rapid and unprecedented increase in ocean plastics since 2005, according to a new study.
Published Flat plate bow covers pave way for more economical shipping by improving ship aerodynamics
(via sciencedaily.com) Ships are the main modes of transport for global trade as they are efficient and effective. Improving the aerodynamic performance of ship could reduce fuel consumption and improve speed, further improving the economics of shipping. Recently, researchers from have demonstrated that flat plate bow covers on ships can reduce overall wind drag in ships by nearly 40%, which could lead to enormous fuel savings.
Published Long-term exposure to nitrate in drinking water may be a risk factor for prostate cancer
(via sciencedaily.com) The nitrate ingested over the course of a person's adult lifetime through the consumption of tap water and bottled water could be a risk factor for prostate cancer, particularly in the case of aggressive tumors and in younger men.
Published To help dry forests, fire needs to be just the right intensity, and happen more than once
(via sciencedaily.com) Research into the ability of a wildfire to improve the health of a forest uncovered a Goldilocks effect -- unless a blaze falls in a narrow severity range, neither too hot nor too cold, it isn't very good at helping forest landscapes return to their historical, more fire-tolerant conditions.
