Can pallid sturgeon hang on in the overworked Missouri River?

Chrrrrp, chrrrp: Our headphones echo with the tinny peeps of a radio-tagged pallid sturgeon (Scaphyrincus albus). Dave Fuller, a Montana Department of Fish, Wildlife and Parks fisheries technician, maneuvers the jet boat up and down the Missouri River on a beautiful October day. The sapphire sky has yet to succumb to winter’s haze, and the […]

Pallid’s PR problem

For a large, ancient and extremely endangered species, the pallid sturgeon receives remarkably little respect. The fish is nobody’s poster child. Unlike trout and salmon, it has no real champions among environmental groups; it occasionally gets passing mention, but little direct advocacy, and few are actively engaged in the recovery effort. Pallids spend their entire […]

Even pests have a purpose

It’s a remarkable achievement: According to a census in April, the number of California condors, one of the largest and most endangered birds in the world, has reached 405, including both wild and captive birds. That’s the most condors to exist on the planet since recovery of the species began in the 1980s, when only […]

Surveying the oft-snubbed (and very cool) spider with citizen scientists

It’s Saturday morning in early May at the Bluff Lake Nature Center, a modest suburban oasis in northeast Denver. An eager posse of spider hunters clusters around its intrepid leader, Paula Cushing, a petite woman with a dark braid, deep-set eyes and a fearless affection for eight-legged creatures. “Without spiders, we’d be up to our […]

Temporal shift

But a recent study published in the current issue of the journal Ecology suggests that the Earth’s warming climate is jeopardizing the bird and lily’s temporal bond. According to the researchers, earlier snowmelt in the mountains (brought on by warming temperatures) has, in turn, led to a blooming shift in the lily, the first blossoms […]

The power and plight of the parasite

As the April census indicates, the recovery programs have been a great success, pulling the magnificent bald-headed birds–which sport wingspans of nearly 10 feet and which can live for more than 60 years–from the brink of extinction. But in the process, another, somewhat less charismatic creature, has been wiped out: Colpocephalum californici, an avian chewing […]

Dead trees, biodiversity, and the black-backed woodpecker

The ruins of scorched or beetle-killed forests may not seem like ecological havens. But myriad species depend on standing dead or dying trees, including the black-backed woodpecker, which haunts skeletal forests in the West, Alaska and Canada. Its ebony dorsal plumage blends in with the charred tree trunks on which the bird rummages for juicy […]

From gust to gale

The Energy Integrity Project is one of a growing number of “grass-roots” groups around the country that aggressively lobby against regional wind development projects and renewable energy policies.  And while most are small, NIMBY-type outfits, documents recently obtained by the Checks & Balances Project — a government and industry watchdog organization — suggest that these […]

A towering problem

Imagine it’s a cool autumn evening and you are a small songbird winging southward after an exhausting breeding season in Canada. The hazards of the terrestrial world — hungry cats, window-skinned skyscrapers, careless drivers — have melted away. Up here, one thousand feet above the Earth, it’s smooth sailing. South America — and its feast of insects — awaits. In the 1950s, reports […]

Braving landfills, dodging avalanches, all for the sake of geoscience

On a chilly October morning, Fred Jenkins strides across the West Garfield County landfill. Past hunkered-down dumptrucks and mountains of appliances alive with chattering magpies, he stops at what appears to be a tripodal alien spore. It’s a global positioning system (GPS) monument that Jenkins helped install in this sage-speckled swath of western Colorado five […]

Predator aversion

The delisting quickly led to state-sponsored wolf hunts in Montana and Idaho that were supposedly aimed at responsibly reducing wolf populations to protect game species like elk. But for many wildlife conservation groups, the hunts have amounted to little more than the state-sponsored slaughter of a still-endangered species sacrificed for the sake of politics. Last […]
