Research reveals three new marsupial species -- though all likely extinct      (via sciencedaily.com)     Original source 

The exciting discovery of three new species of a small Australian marsupial has been tempered by the sad fact that each of the newly identified species of mulgara is likely already extinct.

Bitcoin mining has 'very worrying' impacts on land and water, not only carbon      (via sciencedaily.com)     Original source 

As bitcoin and other cryptocurrencies have grown in market share, they've been criticized for their heavy carbon footprint: Cryptocurrency mining is an energy-intensive endeavor. Mining has massive water and land footprints as well, according to a new study that is the first to detail country-by-country environmental impacts of bitcoin mining.

Raining cats and dogs: Global precipitation patterns a driver for animal diversity      (via sciencedaily.com)     Original source 

A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.

Light, freshwater sticks to Greenland's east coast      (via sciencedaily.com)     Original source 

Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island.  In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.

Climate is increasing risk of high toxin concentrations in Northern US lakes      (via sciencedaily.com)     Original source 

As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.

Land use: Producing more food and storing more carbon      (via sciencedaily.com)     Original source 

Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.

Soil carried on sea freight loaded with dangerous pests and diseases, research finds      (via sciencedaily.com)     Original source 

While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.

DNA shows where Washington culvert replacements helped spawning salmon      (via sciencedaily.com)     Original source 

University and federal scientists used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of environmental DNA, or eDNA, in future environmental impact reporting.

Scientists discover deepest known evidence of coral reef bleaching      (via sciencedaily.com)     Original source 

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.

Protecting polar bears: New and improved radar technology      (via sciencedaily.com)     Original source 

Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results. Researchers hope that improving detection tools to locate dens -- which are nearly invisible and buried under snow -- will help efforts to protect mother polar bears and their cubs.
