War & Fish
by Journal Watch Online in Journal Watch Online
War isn’t the answer — but it wasn’t so bad if you were a Scottish haddock. A 6-year pause in commercial fishing caused by World War II helped cod, haddock and whiting populations in Europe’s North Sea recover from years of pre-war exploitation, according to a new analysis. The “accidental” reserve suggests that cold-water fish […] Read More »... Read more »

Green-trification
by Journal Watch Online in Journal Watch Online
Nobody’s against cleaner, greener neighborhoods. But some social scientists have worried that cleaning up could end up clearing out the poor residents who often live around polluted sites. Now, a study from Portland, Oregon looks for a link between gentrification and environmental clean-up.
Researchers have long documented the impact of LULUs — “locally undesirable land […] Read More »... Read more »

Unsafe Haven
by Journal Watch Online in Journal Watch Online
Being big and hairy is looking scary. The number of large mammals living in nearly 80 African reserves has dropped by more than half since the 1970s, according to a new study. Some reserves, however, appear to be helping big mammals hang on.
Protected areas (PAs) have become a major focus of conservation efforts around […] Read More »... Read more »

Pricing Protection
by Journal Watch Online in Journal Watch Online
Protecting ocean habitat can be a bit like buying laundry detergent: Better to buy in bulk. A first-ever effort to put a price tag on the cost of setting up new marine protected areas (MPAs) finds that costs can vary, but that bigger reserves deliver more bang for the buck. Researchers calculate that planners have […] Read More »... Read more »

Bog Versus Biofuel
by Journal Watch Online in Journal Watch Online
Could our growing thirst for biofuels swamp efforts to restore Europe’s wetlands? Not necessarily, finds a complex new analysis of how conservation, energy and farm policies can collide. But exactly how policymakers set the rules may make a big difference to the cost and effectiveness of efforts to protect and expand mires, marshes and bogs. […] Read More »... Read more »

Tadpole Ripples
by Journal Watch Online in Journal Watch Online
Tadpoles can leave ripples in a stream – even when they are gone. With a deadly fungus causing catastrophic declines in tropical frogs, many streams are losing their tadpoles. The loss of the wrigglers can subtly but significantly reorder stream ecosystems, find researchers who are studying the ecological aftermath in Panama.
The chytrid fungus has […] Read More »... Read more »

Porcupine Laundry
by Journal Watch Online in Journal Watch Online
It’s a longstanding idea: Take pressure off wild animals threatened by overexploitation by encouraging farmers to raise and sell them. A new study from Vietnam, however, suggests that commercial farming is doing more harm than good for a porcupine that’s popular on the dinner plate. That’s partly because some farmers appear to be “laundering” porcupines […] Read More »... Read more »

Flying Blind
by Journal Watch Online in Journal Watch Online
What you can’t see can kill you. Researchers investigating why some birds are especially prone to hitting power lines have discovered that they literally can’t see where they are flying. That means typical anti-collision efforts, such as hanging warning markers on transmission lines, won’t help fowl that fly blind.

Heroic Fungi

Talk about your historic biodiversity. A polar hut built by famed Antarctic explorer Ernest Shackleton turns out to house an extraordinary array of fungi. The discovery could help conservators preserve the landmark structure, and offers new insights into life on a continent once viewed as barren.

Climate change could hold some surprises for some of the world’s poorest people.

Beach House Chicks

What could be better than a nice view of the surf, a little sand — and survival? Australian researchers have found that providing threatened shorebirds with simple A-frame “chick houses” made from plywood can dramatically increase the survival of young birds. But they aren’t sure exactly why the avian architecture helps.

Mercury Rising

Mercury is flowing with the melt. A new study from Sweden finds that thawing permafrost in a northern peat bog is releasing the toxic metal into a nearby lake. That pattern could become widespread as global temperatures rise, the authors warn.

Dung Gone

Scat. Dung. Droppings. Feces. Call it what you will, excrement is often treasured by wildlife biologists. It can tell scientists what an animal is eating, if it is healthy or sick, and each load carries a trove of identifying DNA. Tracking turds is also a longstanding, non-invasive method for monitoring rare, secretive species, such as […] Read More »... Read more »

From Fire, Coral

The destruction was epic. When the volcano Krakatau erupted on August 26, 1883 on an island in the Sunda Strait near Indonesia, molten rock flows caused the seas to boil. Layers of lava and ash up to 20 meters thick carpeted the seafloor, snuffing out all marine life within 15 kilometers of the peak. Now, […] Read More »... Read more »

In Cold Blood

Even a big new reserve may not be enough to protect Spain’s threatened lizards, turtles and salamanders from climate change. Warming temperatures could dramatically restrict — or even eliminate – habitat for these cold-blooded “ecotherms,” which can’t regulate their body temperatures like “warm-blood” mammals and birds. The finding suggests conservationists need to take physiological differences […] Read More »... Read more »

Dead Zone Entrée

You already know your carbon footprint. How about your “nitrogen footprint”? Researchers have calculated how much nitrogen pollution is produced by the production of common foods. Ultimately, they hope the approach might help consumers curb nutrient pollution that is creating oxygen-poor “dead zones” in many coastal seas.
Over the last few decades, researchers have documented […] Read More »... Read more »

Plankton Doom?

Climate change may be taking the bloom off the plankton. Researchers say they’ve found “unequivocal” evidence of long-term declines in the ocean’s teeming populations of microscropic algae, which form the base of the marine food web. Warming surface waters appear to be a main culprit, the researchers report in today’s Nature.
