Tetrapod Zoology

August 27th, 2010

The blog Tetrapod Zoology has become a regular stop in my surfing habits.

It’s chocked full of crazy interesting information about animals -common to rare, extant to extinct, and even imaginary to real. The best part about this blog is that it does no dumbing down. Evolutionary origins, research articles, and statistics are all presented in an easy straightforward manner.

An example clipped from a recent post:

“As you’ll no doubt already know, the remarkable morphology of the Matamata’s head and neck correlates with a remarkable feeding behaviour. Like various other turtles that lurk, concealed, on the bottoms of ponds, lakes and rivers, matamatas are (usually!) cryptic lunge-feeders that wait for small prey (typically fish) to come close…

Once the prey is within range, the Matamata engages in dynamic suction-feeding: a feeding Matamata gapes its jaws really wide (opening them to an angle of about 80°), and rapidly expands its throat to suck in a huge quantity of water – hopefully containing the prey. Structures normally present on the pleurodire palate (and apparently restricting their gapes to between 40-65°) have been strongly reduced (as discussed in the article on skull and hyoid anatomy). It’s fairly easy to get a Matamata to indulge in this behaviour if you tease it with bits of meat, or wiggle your fingers around in front of its face. Ordinarily, this sort of thing is only recommended when there’s a sheet of glass in the way, but it’s reported by people who have experienced matamata ‘attacks’ that their bites aren’t actually that painful. And they shouldn’t be, given the weak jaws, absence of beak tissue, and importance of suction and engulfment of water.”

NASA Images of Twin Cities Flooding

Check out this neat imagery from NASA:

From the NASA Earth Observatory Natural Hazards Feed:

“The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured these images of the Twin Cities region on March 17, 2010 (top), and August 5, 2009 (bottom). Both use a combination of infrared and visible light to increase the contrast between water and land. Vegetation appears bright green. Clouds appear sky blue. Water varies in color from electric blue to navy. Bare ground ranges in color from dark brown to tan.

Taken in different seasons—late winter and mid-summer—these images not only show different water levels in the Mississippi and other rivers, but also dramatically different amounts of vegetation. While much of the region is heavily vegetated in August 2009, river levels are low enough to make the water bodies nearly invisible. (Tree cover along the riverbanks may partly obscure the rivers.) In contrast, the image from March 2010 shows vegetation just beginning to emerge from winter’s chill. Differences in vegetation between August and March are especially visible in the west, in what appears to be a large patchwork of agricultural lands. Compared to the previous summer, the Mississippi and other rivers in the region appear swollen. Some of the electric-blue hues in water bodies away from the rivers might result from lingering ice. Springtime rains and snowmelt often conspire to raise water levels.”

A research ship recently docked back home after weeks out at sea studying plastic in the ocean. You can read about the fascinating trip and see amazing photos on their blog. Or check out the official website.

Their destination was a location in the Pacific Ocean, far off the coast of California, where sea currents converge and cause a mass gathering of plastic. The plastic gathering isn’t a floating raft; but small pieces suspended at varying depths.

These plastic pieces probably leech chemicals into the water but they also act like magnets attracting hydrophobic industrial and agricultural chemicals – which are suspected to be consumed by small fish and work up the food chain to top-level-consumers like us.

Interestingly, larger pieces of ocean plastics become homes to pelagic creatures like crabs, algae, flying fish eggs. They anticipate needing six months (or more) to analyze all the data – should be some interesting results!






How to Excite Teens about Science

May 14th, 2009

Here is a video made by the Biology Class of Miss Baker:

Its really interesting to hear so many of the students say they would like to have people with science careers come into the classroom and talk to them about it. It seems like a no-brainer, but we are not doing it enough.

Miss Baker is a biology teacher who’s class has a blog, and who has her own blog about using blogs for science education. Very exciting and inspiring – she is meeting the students where they are and it is obviously engaging them.

I wonder if local nature centers could engage with schools by using blogs/facebook/twitter etc. Maybe they could even partners with a local biology class to set it up and run the blog for a school year, or get a summer intern. If any organizations are interested in this idea and would like some help setting it up, please contact me.

Phenology

Project BudBurst

Project BudBurst

Springtime always peaks my interest in phenology. Recently, I went to a local book seller and inquired if they sold phenology journals, the women at the book store asked if I had looked in the New Age section. Right away I knew her mistake, “Not Phrenology,” I said, “Phenology.”

Here is a list of phenology resources from people and organizations who definitely wouldn’t make the same mistake.

The Minnesota Conservation Volunteer has a great young naturalists article on Phenology, including a teachers guide.

Project BudBurst is “is a national field campaign for citizen scientists designed to engage the public in the collection of important climate change data based on the timing of leafing and flowering of trees and flowers. ”

The National Sustainable Agriculture Information Service’s extensive phenology page.

John Latimer, of Grand Rapids, hosts an interesting phenology radio series with the MP3s available on his website.

Red Wing Nature Notes is group blog which holds true to its name.

And the Star Tribune reports that this week the first barge plowed upstream through the ice at Lake Pepin.

International Children's Digital Library

International Children's Digital Library

The International Children’s Digital Library is wonderful website full of great resources for educators, parents, and anyone who loves children’s literature and illustration. 

There are many science and nature themed books with high-res scanned images of all of the pages, including the illustrations. And many of the book’s copyrights have expired so you can used the illustrations for programs. The organization has even developed a Teacher Training Manual

“the mission of the International Children’s Digital Library Foundation is to prepare children for life in an ethnically and culturally diverse world by building the world’s largest online multicultural repository of children’s literature.”

Public Domain Children’s Graphics

I think I may have found a great potential resource for environmental educators on BoingBoing today: A website called Grandma’s Graphics is full of free public domain images which I think are pulled from old children’s books. 

BUT there have been so many people visiting, and trying to visit, Grandma’s Graphics who saw it on BoingBoing that it broke the website. I’m sure it will be fixed shortly, and then we can see if this a treasure cove of images or a dud.

Digital Youth Research

I’ve recently come across some great research and information about the way teenagers use the internet and social networking. I just started reading it all, but I think this research can provide insight about how to achieve our organizations’ missions by better utilizing new media and social networking. While the studies focus on teenagers, people of all ages – especially young adults – are plugged-in.

The Digital Youth Project: (here is a nice overview via boingboing)

“Kids’ Informal Learning with Digital Media: An Ethnographic Investigation of Innovative Knowledge Cultures” is a three-year collaborative project funded by the John D. and Catherine T. MacArthur Foundation. Carried out by researchers at the University of Southern California and University of California, Berkeley, the digital youth project explores how kids use digital media in their everyday lives.



Taken Out of Context
American Teen Sociality in Networked Publics
 
(doctorial dissertation by Dr. danah michele boyd)

From the Introduction:
“While teenagers primarily leverage social network sites to engage in common practices, the properties of these sites configured their practices and teens were forced to contend with the resultant dynamics. Often, in doing so, they reworked the technology for their purposes. As teenagers learned to navigate social network sites, they developed potent strategies for managing the complexities of and social awkwardness incurred by these sites. Their strategies reveal how new forms of social media are incorporated into everyday life, complicating some practices and reinforcing others. New technologies reshape public life, but teens’ engagement also reconfigures the technology itself. “
