Protecting the Amargosa: From Suspicion to Support for a Desert River
Anti-environmental sentiments in rural Nevada have been in the news a lot lately. Here's a different narrative. In the Mojave Desert of remote Nevada and California, conservationists are part of the community and working to overcome suspicion to protect a vibrant river.
Pupfish: Conserving a Mojave Desert Survivor
Sure, desert pupfish are tough. Hot water temperatures? They thrive in it. Creeks saltier than the ocean? No problem. But now pupfish face a bigger challenge -- people and their need for lots of water.
Chasing Cod: Tracking a Fish to Save an Industry
Cod is as much a part of Eastern Massachusetts as the Red Sox. But the fishery has been in long-term decline. Can tracking cod help save them...and an industry?
Scuba Divers Provide Non-Chemical Weed Control on Wisconsin Lake
Eurasian watermilfoil, meet your worst enemies: scuba divers and snorkelers. A chemical-free, cost-effective method of aquatic weed control offers promising results on a Wisconsin lake.
Lose the Memory, Lose the Fish
A dead river runs through it? We've come to accept our current, degraded rivers as normal, even though they once held almost-incomprehensible numbers of migratory fish. Can ecological history be a first step in reclaiming our memory and our fish?
A Breakthrough for Data-Poor Fisheries Starts in Palau
Find out how a new technique piloted in Palau by The Nature Conservancy could help solve one of the world’s greatest challenges in fisheries management — a simple, low-cost method for assessing fish stocks.
Weird Nature: Shrew-Eating Trout!
The story of rodent-eating trout at The Nature Conservancy's Silver Creek Preserve has been one of our blog's biggest hits. But those Silver Creek trout look like dainty eaters compared to this one. Meet the shrew-eating trout documented by researchers at Alaska's Togiak National Wildlife Refuge. And how did this many small mammals end up in a trout's stomach?
Big Fish: Rodent-Eating Trout
Key up the Jaws soundtrack. For years, anglers have claimed Silver Creek's brown trout feed on rodents. Does the science back them up?
Oceans and Climate Change: Protecting the “Invisible”
Coral bleaching, increasing storms, the loss of polar bears: many impacts of climate change are already vivid in our minds. We naturally worry about the things we can see. Huge waves and the loss of big fish and colorful corals get our attention. But what about things we can’t see, like the tiny creatures called plankton? They are also poised for dramatic changes. A recent dive in the sapphire waters of the Caribbean offers a close encounter with plankton. While most of my dive buddies hurry to reach the bottom, I linger as I usually do, pondering the “blue” and looking out for the visible and the invisible. Suddenly, clouds of tiny filaments come sharply into focus. It’s blue-green algae--Trichodesmium--a type of phytoplankton that plays an important role in these nutrient-poor waters. They essentially break gaseous nitrogen’s tough triple bond and convert it into a form other phytoplankton can feed on. What would these waters look like without them?
