    A freshwater, saltwater tug-of-war is eating away at the Everglades

    The boardwalk at Pa-hay-okee Overlook is a brief, winding path into a dreamworld in Everglades National Park. Beyond the wooden slats, an expanse of gently waving saw grass stretches to the horizon, where it meets an iron-gray sky. Hardwood tree islands — patches of higher, drier ground called hammocks — rise up from the prairie like surfacing swimmers. The rhythmic singing of cricket frogs is...

    Shallow reef species may not find refuge in deeper water habitats

    Deep water reefs are unlikely to be safe harbors for many fish and coral species from shallow reefs threatened by climate change and human activity. Shallow water creatures may have trouble adapting to conditions in the deep, scientists report in the July 20 Science. Plus, deep reefs are facing the same threats that are putting shallower ones at risk.

    The study deals a blow to the “deep...

    Bird poop helps keep coral reefs healthy, but rats are messing that up

    When invasive rats chow down on island seabirds, coral reefs suffer.

    Researchers studied islands with and without the rodents in the Chagos Archipelago in the Indian Ocean. On rat-free isles, there were on average 1,243 birds per hectare compared with about two birds per hectare on rat-infested islands, the team found. And these rodentless islands had healthier coral reef ecosystems. The...

    Though found across the world, the orange-and-brown beauties that live in Southern Europe migrate into Africa each fall, crossing the Sahara on their journey (SN Online: 10/12/16). But what happened after was a mystery because the butterflies disappeared. Researchers...

    Treating roads with oil and gas wastewater may spread harmful pollution

    Each year, finding and extracting oil and gas for energy produces hundreds of billions of gallons of wastewater in the United States. When recycled and spread on roads, the wastewater can leak its contaminants, including salt, radioactive elements and chemicals that interfere with hormones, into groundwater and surface water, researchers report May 30 in Environmental Science and Technology....
