Mass Migrations May Face Mass Extinction

Wildebeest Migration at Sunset

25% of all the world’s large-scale terrestrial migrations have already ceased due to habitat loss and human-caused changes to the landscape, and it may not be long before all migrations disappear entirely.

That according to a new study, which warns that with continued population growth, development and habitat encroachment, storied epics like those of wildebeest parading across the Serengeti or herds of bison rumbling across North American plains shall become tall tales of the past.

Stephen Colbert Has New Species Named After Him

Researchers at Arizona State Univerity and the University of New Mexico have named a Venezuelan diving beetle Agaporomorphus colberti in honor of the humorist.

One of the outstanding features of the species is the genitalia of the males. “This new species is similar to members of a clade within the genus exemplified by A. knischi…and unique in having similar, extremely complicated male genitalia…”

100-200 New Amphibians Discovered in Madagascar

A recent study documented the discovery of 100-200 new amphibian species in Madagascar.

One of the researchers, Dr. Miguel Vences, stated: “People think that we know which plant and animal species live on this planet. But the century of discoveries has only just begun – the majority of life forms on Earth is still awaiting scientific recognition.”

Sea Otter Pops Up in Oregon Waters, Where They Have Been Extinct

A sea otter sighting has been confirmed in Oregon near Depoe Bay. There have been no confirmed sightings of the creature in Oregon waters since 1906. Morris Grover spotted the animal but did not want to tell anyone until he sent photos of it to biologists and they told him what he photographed. They identified it as a sea otter. (Many river otters there have been mistaken for sea otters).

635 Million-Year-Old Animal Traces Discovered

New research in the South Oman Salt Basin shows evidence of animal life dating back much further than the first appearance of other significant life forms.

Chemical traces of the minute marine sponges, called demosponges were observed by a research team led by the University of California, Riverside geochemist Dr. Gordon D. Love. Desmosponges include the species most consumsers are familiar with: the bath sponge. These over 500 million-year-old sponges however, were probably much smaller due to a lack of oxygen available during their geological period. The fact that they existed 200 million years before plants appeared on land, shows just how very old they are.

New Study: California Native Fish Species to Be Extinct by End of Century

California Wild SalmonTwenty of 31 species of prized native fish species in California are in serious decline, according to a new study by Peter Moyle, UC Davis professor of conservation biology. Unless the state acts quickly, these species face extinction by the end of the century. Professor Moyle explains:

Our fish need cold, clean water to survive, but they’re getting less and less of it. Dams block access.

Biofuels And Security: Shedding My Western-Centric Worldview (Opinion)

Editor’s Note: I was in Houston, TX, last week, celebrating the International Year of the Planet at the first ever joint meeting between the American societies of Soil Science, Geology, Crop Science and Agronomy. With a significant focus on biofuels, this conference was rife with interesting materials.

In what could be my biggest personal revelation since diving into the world of alternative energy, it dawned on me last week that the “western” biofuel players are certainly the loudest kids on the block, but not really the most important.

I spent a large part of my time at the conference just trying to sort out which of the dozens of excellent forums on biofuels, energy, and environmental quality I should attend. The rest of my time was taken up with trying to keep my head together enough to make sense of it all so I could convey it in a way that’s meaningful to you, my readers.

But, while running around like a kid in a candy store, I became aware that my understanding of biofuels was decidedly myopic. Up until last week, I was squarely focused on U.S., E.U., and, to a smaller extent, Brazilian policies — quite naturally and unapologetically, I might add. After all, I am a U.S. citizen and I have a profound connection to my country and it’s cultural peers.

German Scientists Discover 120 Million Year Old Bizarre Ant in Amazon Forest

German Scientists Discover 120 Million Year Old Bizarre Ant in Amazon ForestGerman biologists have discovered an hitherto unknown ant species, believed to be the oldest on the planet, deep in the Amazon rain forest.

Field researchers from Karlsruhe’s Natural History Museum who made the discovery near Manaus, Brazil, say the species, which resembles miniature wasps and looks like no other, may date back around 120 million years, according to Reuters.

Martialis heureka, nicknamed the “Ant from Mars” due to its unusual features and heureka from its surprising discovery, the ants themselves are eyeless, pale in color, subterranean, and predatory, according to Wikipedia.

Turning Brownfields Into Biofuels

What if you could use plants to turn industrial waste sites into fertile, productive cropland? Better yet, what if you could produce biofuels in the process? By marrying bio-remediation and crop production, a group of Carnegie Mellon University graduates hopes to do just that: produce biodiesel and ethanol on reclaimed land.

"It’s a proven technology, but in an unproven environment," said Mr. Butcher, 27. "The idea of growing energy crops is
