Scientists discover pristine deep-sea coral reefs in the Galápagos Marine Reserve      (via sciencedaily.com)     Original source 

Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) -- the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.

Temperature, drought influencing movement of Plains bison      (via sciencedaily.com)     Original source 

Temperature and severe drought can drive movement among herds of Plains bison, says a recent study. The team's GPS-backed data suggests that conserving the once-endangered species could depend on accounting for the climate extremes that Plains bison will likely encounter moving forward.

New look at climate data shows substantially wetter rain and snow days ahead      (via sciencedaily.com)     Original source 

A new look at climate data shows that, by the end of the century, the heaviest days of rain and snowfall across much of North America will likely release 20 to 30 percent more moisture than they do now. Much of the increased precipitation will occur in winter, potentially exacerbating flooding in regions such as the upper Midwest and the west coast. Researchers also found that heavy precipitation days historically experienced once in a century will become more frequent -- as often as once every 30 or 40 years in the Pacific Northwest and southeastern United States.

Wildfires and animal biodiversity      (via sciencedaily.com)     Original source 

Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.

Increased droughts are disrupting carbon-capturing soil microbes, concerning ecologists      (via sciencedaily.com)     Original source 

Soil stores more carbon than plants and the atmosphere combined, and soil microbes are largely responsible for putting it there. However, the increasing frequency and severity of drought, such as those that have been impacting California, could disrupt this delicate ecosystem. Microbial ecologists warn that soil health and future greenhouse gas levels could be impacted if soil microbes adapt to drought faster than plants do.

A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces.  When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.

Stopping storms from creating dangerous urban geysers      (via sciencedaily.com)     Original source 

Researchers develop a computational model of stormwater piping to study storm geysers. They used this model to understand why storm geysers form, what conditions tend to make them worse, and what city planners can do to prevent them from occurring. The authors say the best cure for a storm geyser is bigger pipes; however, that advice is little help to cities with existing pipeline infrastructure. In these systems, the focus must be on minimizing the potential damage by reducing the height of the geysers, the volume of expelled water, or the resulting damage to the pipeline.

Lightning strike creates phosphorus material      (via sciencedaily.com)     Original source 

A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.

Trees in areas prone to hurricanes have strong ability to survive even after severe damage      (via sciencedaily.com)     Original source 

The island of Dominica took a direct hit from Category 5 Hurricane Maria. Nine months afterward, researchers found that while 89% percent of trees located in nine previously documented forest stands were damaged, but only 10 percent had immediately died. The most common damage was stem snapping and major branch damage. The damage with the highest rates of mortality were uprooting and being crushed by a neighboring tree. Large individual trees and species with lower wood density were susceptible to snapping, uprooting and mortality. Those on steeper slopes were more prone to being crushed by neighboring trees.

Cities will need more resilient electricity networks to cope with extreme weather      (via sciencedaily.com)     Original source 

Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.

Family tree of 'boring' butterflies reveals they're anything but      (via sciencedaily.com)     Original source 

Important species often get overlooked if they lack flashy colors or charismatic behavior. This is true of euptychiine butterflies, one of the most common insects in the Amazon Rainforest that have been largely ignored by scientists and naturalists throughout the 20th century. A new study pieces together the natural history of the group, in which males can look so unlike females, they've been repeatedly mistaken for separate species, diversity has been drastically underestimated, and more than 100 unnamed species are waiting on scientific description.

Underground water could be the solution to green heating and cooling      (via sciencedaily.com)     Original source 

About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this sector by 40% in the United States. The approach, called aquifer thermal energy storage (ATES), could also help prevent blackouts caused by high power demand during extreme weather events.
