The International Union for Conservation of Nature surveyed 47,677 of animal and plant species this year, ultimately listing 17,291 of the count under Red’s List of endangered species.
The Switzerland-based environmental group conducts a yearly examination of plant and animal species and 2009’s list topped last year’s by 2,800. However, the group admitted that the list is incomplete, and there remain millions of other specimens yet to be surveyed.

When I first read the news that NASA was going to start experimenting on monkeys with radiation to study the effects of deep space travel, my heart sunk. As an anthropologist who has studied non-human primates I have seen up close the emotions, the feelings, and the physical qualities we share with our evolutionary cousins. My mind went back to shooting chimps into space, not caring if they lived or died. To cruel (and now illegal) experiments of all kinds performed on our closest living relative.
Now NASA is planing to irradiate squirrel monkeys. Scientists are particularly interested in studying how the radiation impacts the monkeys’ central nervous systems and behaviors over time. Messing with the monkeys brains. Oh great!

Because of their enormous body size, whales have been thought to contribute a considerable amount of carbon dioxide to the total greenhouse gas build-up whenever they exhale. However, Trish J. Lavery of Flinders University in Adelaide, Australia claims they – the sperms whales of Southern Ocean, at least – are falsely-accused and that they live quite a carbon-neutral life.
During the October 13 Biennial Conference on the Biology of Marine Mammals in Quebec City, Canada, Lavery talked about earlier calculations overlooking the whales’ capacity to offset their carbon dioxide emissions. The 210,000 sperm whales in Southern Ocean should be declared carbon neutral, according to Lavery. The carbon neutral status is achieved by bringing iron from the depths of the ocean to the surface whenever they feed. This extra iron in the water induces plankton growth which in turn traps carbon and prevents it from being released into the atmosphere.
If you’re a fan of the Sundance Channel’s series Green Porno with Isabella Rossellini, you’re probably already aware that the acclaimed show launched its third season on Monday (with a focus on marine animals). But how well do you really know the mating habits of various animal species?
In order to celebrate the new season, we’ve agreed to host another event with the show… this time a quiz (which you’ll find below the jump). Answer the questions below in the comments; if you score 80% or above (that is, only miss two questions), you’ll be entered into a drawing for a Sundance Channel prize package that includes:
- Ella Vickers bags, made out of recycled sails
- 1 Bag at a Time farmers market bags
- A Boku journal made from recycled paper
- Sundance pen
- Sundance Channel t-shirt (made from organic cotton)
- Sundance Channel hat (made from organic cotton)
Ready to get started? Here’s the quiz (and links to videos with the answers… this isn’t that hard)

Communities of all sorts are being disturbed by the fires in California. As another result of climate change, bird communities are expected to see some big changes in other ways, according to a new report released on September 1.

Ric O’Barry reports that the horrific annual dolphin slaughter in Taiji has been suspended due to publicity from the film, The Cove.
September 1st usually marks the first day of the year for the brutal killings, but for the first time the Japanese media has arrived in Taiji en masse, causing the local fishermen to pause while the world takes notice.

The northern Madagascar spider tortoise, one of the three subspecies of Pyxis arachnoids, is currently facing a threat to their population brought about by poachers.
The spider tortoise is small compared to other tortoise species, and is characterized by the presence of web-like patterns on adult shells. The northern Madagascar spider tortoise subspecies (P. a. brygooi) can only be found in a narrow strip on the coast. Since they’re endemic and hence, can easily be caught, the subspecies is currently “extinct across 50% of its former historical range.” Senior wildlife biologist at Nautilus Ecology UK, Ryan Walker, conducted this population survey last March, and came to the conclusion that the wild population of the northern Madagascar tortoise has fallen by 90%, mostly due to massive collection for illegal pet trade.
Both economic theory and experimental data concur–increasing the distance traveled to find food incurs “negative fitness consequences”, by decreasing total energy for maintenance, repair and reproduction. Yet, most animals must travel to find food. Individual, small groups, and large herds of eutherian (placental) mammals–like wild buffalo, gazelles, lions, and elephants–often travel great distances to find food. This expenditure of energy, at the apparent risk of biological fitness, has puzzled zoologists for some time.
