This would be a good poster for geography, biology, general science and world history courses. Can your drafting class print this out for you in poster format?

When all of the “coal mine canaries” on Earth die out, how much longer have humans left to live on Earth?

What hope have we, with yahoos like this leading us in Congress?

Can the Houston toad survive Texas wildfires and droughts?

November 25, 2011

New short from the Texas Parks and Wildlife people:

The smoke may be gone but the Bastrop fires of Labor Day weekend are still a smoldering concern for biologists. They’re keeping tabs on the Houston Toad. And with only an estimated 2,000 left in Texas, this endangered species is facing its next challenge as the drought continues. More on Houston toads at http://www.houstonzoo.org/HoustonToad/

For background, see this earlier reel from TPWS on the fires at Bastrop State Park:


Joy of pollination, according to Louie Schwartzberg

November 21, 2011

It’s a TEDS Talk, of course

Birds do it, bees do it, even educated fleas do it.  Plants do it, too, but often with the help of animals.

Here are some of the most glorious pictures of sex you’ll ever see, filmed by Louie Schwartzberg.  Anyone who has ever tried to take a good photograph should marvel at these shots, and the skill and artistry and luck it took to get them:

What will we do if the bees vanish?

The lowdown:

http://www.ted.com Pollination: it’s vital to life on Earth, but largely unseen by the human eye. Filmmaker Louie Schwartzberg [of Moving Art] shows us the intricate world of pollen and pollinators with gorgeous high-speed images from his film “Wings of Life,” inspired by the vanishing of one of nature’s primary pollinators, the honeybee.


Evidence of evolution: Giraffe’s laryngeal nerve

October 8, 2011

One of my favorite examples of evolution and how we can see it in living things today:  The laryngeal nerve of the giraffe, linking larynx to brain, a few inches away — but because of evolutionary developments, instead dropping from the brain all the way down the neck to the heart, and then back up to the larynx.  In giraffes the nerve can be as much as 15 feet long, to make a connection a few inches away.  Richard Dawkins explains:

All mammals have the nerve, and as a result of our fishy ancestry, in all mammals, the nerve goes down the neck, through a heart blood vessel loop, and back up.  In fish, of course, the distance is shorter — fish have no necks.

Tip of the old scrub brush to Pharyngula’s Sciblogs site.

Yes, the laryngeal nerve is sometimes called the vagus nerve, because it originates off of the vagus nerve.

Giraffe's laryngeal nerve, easily explained by evolution; paints of picture of an evil, joker designer otherwise.

Watching the drought roll in at Colorado Bend State Park

July 6, 2011

It took me a couple of tries to figure it out — last week when I told people Kathryn and I were off to Colorado Bend State Park to spend time on the river, several people commented about how much cooler it would be there.

What?  West of Killeen about an hour, ten miles of dusty road outside of Bend, Texas (population 1,637), Colorado Bend is not cooler than Dallas.  It was over 100° F every day we were there, stayed well above 90° most  of the nights.

Kathryn Knowles checking wildflowers, Colorado River, Texas

Kathryn studied wildflowers at a spring at the side of the Colorado River during a break from kayaking; this spring's flow was reduced, but still moist enough to create a near-oasis.

Our well-wishers were geographically confused.  They thought we were headed to the Colorado River in Colorado, not the Colorado River in Texas, which is not the same river at all.  I didn’t bother to check the temperatures in Colorado, but one might be assured that it was cooler along the Colorado River in Colorado than it was along the Colorado River in Texas.

It was a return trip.  We stumbled into the park 16 years ago with the kids, for just an afternoon visit.  The dipping pools  in the canyon fed by Spicewood Springs captivated us.  It took a while to get back, and then the kids were off doing their own thing.

So, just a quick weekend of hiking/camping/kayaking/soaking/stargazing/bird watching/botanical and geological study.   Park officials closed the bat caves to human traffic in hope of keeping White Nose Syndrome from the bats; we didn’t bother to sign up for the crawling cave tour through another.

Ed Darrell at Colorado Bend State Park, Texas

The author, still working to master that Go-Pro camera on the hat -- some spectacular shots, but I don't have the movie software to use it all; you know it's hot when SPF 75 sunscreen is not enough.

What did we see?  Drought has a firm grip on Texas, especially in the Hill Country, especially outside of Dallas.  The Colorado River  is mostly spring fed; many of the springs are dry.  No water significant water flowed through the park while we  were there — kayak put-ins have been reduced to the downriver-most ramp, and the bottom of the boat launch ramp is three feet above water.  Gorman Falls attracts visitors and scientists, but the springs feeding it are about spent this year — just a few trickles came over the cliff usually completely inundated with mineral-laden waters.

Drought produces odd things.  The forest canopy around the park — and through most of the Hill Country we saw — is splattered with the gray wood of dead trees, many of which at least leafed out earlier this spring.  The loss to forests is astonishing.  Deer don’t breed well in droughts; deer around the campsites boldly challenge campers for access to grasses they’d ignore in other seasons.  One ranger said he hadn’t seen more than about three fawns from this past spring, a 75% to 90% reduction in deer young (Eastern White Tail, the little guys).  Raccoons are aggressively seeking food from humans, tearing into tents and challenging campers for food they can smell (lock your food in the car!).  Colorado Bend is famous for songbirds, including the endangered Golden Cheeked Warbler, and the elusive, spectacular painted bunting.  But the most commonly-sighted birds this year are turkey vultures, dining on the young that didn’t make it healthy into the summer and won’t survive until fall.

Warming denialists’ claims of “not so bad a drought” ring out as dangerous, wild delusion.  (By actual measurement, Texas average rainfall the past nine months was 8.5 inches, the driest ever recorded in Texas, shattering the old record drought of 1917).

Great trip.  Kathryn’s menu planning was spectacular.  The old Coleman stove  — a quarter century old, now, with fuel almost that old — performed like a champ even without the maintenance it needs (later this week).  Other than the hot nights, it was stellar.

Stellar.  Yeah.  Stars were grand.  It was New Moon, a happy accident.  A topic for another post, later.  Think, “Iridium.”

So posting was slow over the weekend.  How far out in the Hill Country were we?  Neither one of us could get a bar on our phones.  We were so far out the Verizon Wireless guy was using smoke signals.

Thoreau was right, you know.

Let’s go to the zoo . . . kitchen

September 28, 2009

Kate closed down Radula, and moved all her blogging to Adventures of a Free Range Urban Primate.

Did you ever wonder what it’s like to work in the kitchen of a zoo?  Kate has the lowdown.

From Urban Primate:  Just to see the scope of whats stored there, in one hand Allyson is holding meatballs. In the other, whole frozen birds . . . complete with feathers.

The photos from that post alone would make a good PowerPoint for some biology class, or a discussion of animals in an elementary class.


Press release on polar bears the climate change skeptics hope you won’t read

August 2, 2009

Why did the self-proclaimed skeptics work so hard to discredit this meeting before it even occurred?  Why have they ignored this press release?

Take it easy! Calm down, stick to the facts! Polar bear photo by Kathy Crane, NOAA Arctic Research Office

“Take it easy! Calm down, stick to the facts!” Polar bear photo by Kathy Crane, NOAA Arctic Research Office

There is no dramatic finding in the release.  After you read it, you’ll probably wonder, too, why climate change skeptics don’t want you to read this press release:

15th meeting of PBSG in Copenhagen, Denmark 2009

PRESS RELEASE

The 15th meeting of the IUCN Polar Bear Specialist Group (PBSG), hosted by the Greenland Institute of Natural Resources, was held at the Greenland Representation in Copenhagen Denmark , June 29-July 3, 2009.  The Polar Bear Specialist Group is composed of researchers and managers representing each of the five circumpolar nations that signed the International Agreement for the Conservation of Polar Bears of 1973.  Since the late 1960s, the members of PBSG have met every 3 to 5 years under the umbrella of the Species Survival Commission of the IUCN (the International Union for the Conservation of Nature and Natural Resources) to review and exchange information, and make recommendations for research and management of polar bears throughout the Arctic.

The PBSG renewed the conclusion from previous meetings that the greatest challenge to conservation of polar bears is ecological change in the Arctic resulting from climatic warming.  Declines in the extent of the sea ice have accelerated since the last meeting of the group in 2005, with unprecedented sea ice retreats in 2007 and 2008. The PBSG confirmed its earlier conclusion that unabated global warming will ultimately threaten polar bears everywhere.

The PBSG also recognized that threats to polar bears will occur at different rates and times across their range although warming induced habitat degradation and loss are already negatively affecting polar bears in some parts of their range. Subpopulations of polar bears face different combinations of human threats.  The PBSG recommends that jurisdictions take into account the variation in threats facing polar bears.

The PBSG noted polar bears suffer health effects from persistent pollutants.  At the same time, climate change appears to be altering the pathways by which such pollutants enter ecosystems. The PBSG encourages international efforts to evaluate interactions between climate change and pollutants.

The PBSG endorses efforts to develop non-invasive means of population assessment, and continues to encourage jurisdictions to incorporate capture and radio tracking programs into their national monitoring efforts. The members also recognized that aboriginal people are both uniquely positioned to observe wildlife and changes in the environment, and their knowledge is essential for effective management.

The PBSG recognizes that where habitats are stable, polar bears are a renewable resource, and reaffirmed its support of the right of aboriginal groups to harvest polar bears within sustainable limits.  The PBSG noted that the population of polar bears in Baffin Bay, shared between Greenland and Canada, may simultaneously be suffering from significant habitat change and substantial over harvest, while at the same time interpretations by scientists and local hunters disagree regarding population status.  Similarly, the Chukchi Sea polar bear population which is shared by Russia and the United States is likely declining due to illegal harvest in Russia and one of the highest rates of sea ice loss in the Arctic. Consistent with its past efforts to coordinate research and management among jurisdictions, the PBSG recommended that the polar bear populations in Baffin Bay and the Chukchi Sea be reassessed and that harvests be brought into balance with the current sustainable yield.

A variety of management changes have occurred since the PBSG last met in 2005.  The PBSG members were particularly pleased that quotas for the harvest of polar bears in Greenland were implemented in January 2006, and that quota reductions have been implemented in some parts of Greenland.  Also since the last meeting, the government of Nunavut reduced the harvest quota in Western Hudson Bay because of the documented population decline.

The PBSG reevaluated the status of the 19 recognized subpopulations of polar bears distributed over vast and relatively inaccessible areas of the Arctic. Despite the fact that much new information has been made available since the last meeting, knowledge of some populations is still poor.  Reviewing the latest information available the PBSG concluded that 1 of 19 subpopulations is currently increasing, 3 are stable and 8 are declining.  For the remaining 7 subpopulations available data were insufficient to provide an assessment of current trend.  The total number of polar bears is still thought to be between 20,000 and 25,000.  However, the mixed quality of information on the different subpopulations means there is much room for error in establishing that range.  That potential for error, given the ongoing and projected changes in habitats and other potential stressors is cause for concern.  Nonetheless, the PBSG is optimistic that humans can mitigate the effects of global warming and other threats to polar bears, and ensure that they remain a part of the Arctic ecosystem in perpetuity.

Dr. Erik Born from the Greenland Institute of Natural Resources was elected as the new chairman of the group after Dr. Andrew Derocher from the University of Alberta, who has been serving as chair since 2005.

Well, there is that proclamation of optimism in the penultimate paragraph, that humans can mitigate threats to bears, including global warming.  Is that why they don’t want you to read it?

How are the polar bears?  They are in trouble.  The Polar Bear Specialist Group says we should help them out, that we can do things to save the bears.  Why would the “skeptics” not want us to know that?
