Who-Who's There? Owls in the City

Yesterday, my charges & I went on an "urban nature walk" in a local city park. We were looking for signs of wildlife in the heart of the city. Well, squirrels obvious. Lots of squirrels everywhere. But there were signs of other wildlife. Lots of hollows in trees, mounded heaps of earth. But it was hard to really locate these signs. But wildlife does thrive in cities. Sometimes, you just have to visit at the right time -- at night or dusk/dawn. At that very same park, I've seen 2 young raccoons. Good thing observing the botanical wildlife keep us busy. There were a variety of grasses, fungi, trees, and shrubs. We're still trying to learn all of them.

In meantime, enjoy this article about owls: Barred Owls respond well to city life. This is good news because owls are top predators. They prey on squirrels, mice, pigeons, sparrows and other small animals. Predators keep the system balanced and especially in urban environments it can be challeging to keep things in check. So look out for owls in your local park.

Arctic Ice decline is modifying animals behavior

Melting Ice Drives Walrus Ashore. Okay this matter of climate change and the ice caps melting is very serious. Things are changing so much that now the movement and seasonal patterns of animals are being modified. Walruses are predators and when the predators move, that signals a pretty big thing is going on in the ecological community.

Think about the typical food chain. As a predator the walrus depends on primary consumers like fish species and mussels. These creatures consume plant material or microbes. This is also another example of how abiotic factors (like weather, climate, land, and water) can influence biotic systems (plants and animals). No doubt the unexpected presence of walrus in Alaska this time of year will have ripple effect on those local ecosystems.

NC Science Blogging Conference

Okay, I'm really thinking about going to the NC Science Blogging Conference. I really can't afford it and I do have a job. But this sounds SO attractive. Great Professional Development. but who would pay for it. Even more, which friends can I convince to join me there??? Maybe I can convice the job (or the fiduciary agency) to cover some of the costs. After all I am trying to get my subordinates to Blog their learning and service experiences - all of which are science related. A long shot.

Dangit, the Conference Program is terribly attractive, too. And I'm thinking of applying for the AAAS Mass Media Fellowship. If I get accepted the job house will so hate me. Oh, well.

Tagged on ScienceBlogs!

I have been Blog Rolled on ScienceBlogs.com by A Blog Around the Clock. It is a real treat to be mentioned by anyone, especially a well-respected science site like ScienceBlogs.
Thanks, Coturnix.

ScienceBlogs is a growing online community of science bloggers. These scientists blog about every possible science discipline and society issues that stem from or are affected by scientific enterprise.

Oh, and if I'm not too far off, the community is sponsored by the publishers of SEED Magazine.
SEED Magazine is this century's popular science news magazine. I love it. I encourage everyone to get a copy, especially teachers, youth group leaders, and public libary custodians. It includes thought provoking essays, interviews with scientists and science policy makers, and it even includes science crib sheets! That Rocks!
So, please subscribe. Why? Well of the most popular science news magazines (intended for general audiences) like Discover, Popular Science, Popular Mechanics - the average reader is a white male, age 51, college-educated, with a middle income or better. That means there are a LOT of other people not reading about science. Let's see if we can do something about that.

My next recommendation is to check out ScienceBlogs.com and check out some of the essays. The writing style and links may be a little to thick for most of my target audience (teens and young adults) but by all means give it a try. Even I can't make out every word of the blogs about chemistry, space science, and microbiology. So don't feel intimidated.

If you come across something that even remotely touches on something you've covered in class. Print it off. Impress your teachers.

Happy science adventures!

Two scoops please. Arctic Ice is melting, too!

Related to yesterday's post, The North Pole is melting, too. This is very said. I hope there's enough of it left to celebrate International Polar Year until March 2009, when it ends. If you thought those heart-breaking pictures of the polar bears swimming and dying were bad....it's sure to get worse.

Antarctic Ice: hurry up and get a scoop before it's gone!

2007 is International Polar Year celebrating the beautiful, complex, and woefully not-fully comprehended ecosystem of the the Poles. But unfortunately our planet's largest continent and most frozen land mass is loosing its character. Antarctic snow is melting as reported by LiveScience, the matter of climate change is altering our entire planet and the most unique ecosystem.

More Cute Stuff

Okay, I like small rodents - microtines to be exact. Why? Well, because I've worked with them for nearly ten years. So, I couldn't help but share this with you all - the British Vole Appreciation Society. I've worked with meadow voles and prairie voles, so I'm quite partial.

Also, the Missouri Department has a blog now - Fresh Afield. I thought I had a blogroll, but I don't. Sorry about that. I'll add one and include MDC's blog in the line up.

Keep having fun outside!

Urban Wildlife Watch - Coyotes

Coyotes conjure up a lot of different images: Wil E Coyote of Looney Toons or evil bandits that attack sheep and other livestock. But the Coyote, scientific name Canis latrans, are a mixed bag. We typically think of predators species like coyotes as living in rural or big open area nature areas (like pasture ranges, national parks, deserts) but they are capable of living in almost any environment. Coyotes have made a tremendous comeback and populations are spreading far and wide. But interestingly coyote populations don't grow as well when their ranges overlap with wolves - a bigger, badder predator. Coyotes live everywhere, throughout the entire North American continent. They even live in cities, and are sometimes regarded as a nuisance. They are opportunistic. They are great hunters, but they will scavenge a cheap or free meal like trash, road kill, or unsuspecting family pets.

Even in very large, dense urban areas coyotes can survive - well. You may have even have seen one. Doubt it? Although, coyotes look alot like German shepards, there are some differnces. For one, coyotes are much smaller. In fact, coyotes usually weight only 35-40 pounds. Second, coyotes are pretty much light in color all over - a mix of grizzled gray and buff; they don't typically have a dark colored back like most German shepards. But one of the best ways you can you tell the difference between a coyote and dog is to look very closely at how it runs. When a coyote runs, its tail sticks out straight so that the tail is not curled or curved. Second, the tip of the coyote's tail is black. German shepards are not only bigger, but have a curved tail and the tip of the tail is buff color.

Keep your eyes open for these 'top predators' in your neighborhood. But be careful. Never attempt to pet or approach any wild animal, especially a smart predator like the coyote. And keep your pets safe and avoid leaving unsued pet food (or any food) out. Remember, coyotes are in the dog family - so being wild animals, they are likely to carry dog diseases that could make your family pets very ill. Plus, it's best to see these great animals from afar.

“I can tell by just looking at her.”

"I can tell by just looking at her.”
You may have heard this statement before. It’s often said by older women (mothers, aunties, grandmothers, and the like) in reference to a girl they believe has recently lost her virginity. Though such conclusions can’t be definitively confirmed, there are many in our community who place a lot of stock in such deductions. And according to some interesting research being done on adolescent psychology and behavior, our grannies may have been right all along.

One thing that these wise mothers may be cluing into is how a young maiden who has “lost her innocence” behaves and carries herself upon gaining sexual experience. Sex makes teens feel older; and it seems to be especially true for girls. Plus, a teen girl who is dating an older boy or an adult man, tends to rate herself as much more mature than her peers.

Coral Reefs are in trouble

Seems the herp isn't just for humans anymore. Herpes Virus Killing Coral Reefs an article from Live Science.com. But that's not all that's got Coral Reefs singing the blues. Marine Ecosytems around the world are in some serious trouble. In fact, they're very existence is threatened and it coral reefs are destroyed, then the rest of the marine and neighboring terrestrial systems are in trouble, too.

In fact, Scientists who student marine and coral ecosystems are at high alert and have issued a call to action alert. They need signatures NOW for the Scientists’ statement on the reauthorization of the US Coral Reef Conservation Act. Visit the Marine Conservation Blog for more information or find out how you can help.

Urban Wildlife Watch - The Buzz about Bees

Bees are perhaps one of the most interesting urban wildlife creatures. Bees are invertebrate insects belonging to the order Hymenoptera. Hymenoptera include all bees, wasps, hornets, and ants.

Bees like other Hymenopterans are comprised of female-dominated societies. If you’ve ever been stung by one of these creatures it was a female. That’s because the stinger of a bee is a modified ovipositor – or egg laying structure.

In urban areas, most people occasionally encounter bees at the park, open fields, and flower gardens. They can be pesky and even dangerous if you are allergic to bee stings. But bees are also important environmental engineers. Bees help pollinate flowers, trees, and crop plants. When you observe bees buzzing around a field or flowered tree they are doing an important job. Unlike animals, plants can’t move or travel in order to find mates. Bees carry pollen from one flower to another. Pollen is equivalent to sperm of animals. The bees collect nectar of plans and the yellow pollen attaches to their fuzzy abdomen and prickly legs. When they visit the next flower, some of the pollen gets left behind and they pick up new pollen. It’s like an unintentional delivery service for plants.

This seemingly innocent act of transferring pollen is no light matter. Some species plants depend almost entirely on bees for reproduction. That’s why the news of dwindling native bee species is such an alarm. If there are fewer bees or no bees, then we’re in trouble, too. Farmers who grow important crops like wheat, corn, and other grains depend on this simple act of Mother Nature to keep things going. Plus, honey is an important and delicious agriculture product.

So, the next you're outside enjoying the fresh air, keep an eye out for bees. And let me know about your Urban Science Adventures!©

Chicago Public School Students to Assist in Archaeological Dig in Kenya

Two ninth graders from the Chicago Public School District were chosen to work along side archaeologists from the Field Museum of Chicago in Kenya this summer. The trip is being sponsored by Ernst & Young, the major benefactor of the charter school the students attend.
Read more.

Now, I know this isn't urban ecology, but it's just as GREAT! These inner-city students will be doing Science and working alongside college students, graduate students, and professors. This program gives amazing and unique opportuntities to under-served adn under-reprsented students to explore a science career.

I wish them much luck and success.
Science Rocks!

Listening for Bird Songs...At Night

Recently, the Washington, DC. Audubon Society reported that many birds are more active at night than they ever have been before. Why? Urban areas are always full of activity, noise and light. Yes, light and noise pollution maybe signalling to birds that the day is longer than it actually is. Read the full account here.

Invasive Species - Definitely Foe, no Friend

Invasive species are typically non-native or foriegn organisms that have taken up residence in a new place and environment and their growth and spread are out of control.

Why are invasive species a problem?
No Checks & Balances
Species within a given ecosystem depend on each other for survival & population control. When a ‘new resident’ comes into the system, they may not fit in and can throw the whole system off.

Changes the Natural Habitat
Foriegn species alter the abiotic & biotic environment and changes the ability of some organisms to survive
Examples: new trees that native animals can’t live in or eat from, they lose their homes, die or move away
Examples: zebra mussels taking up too much oxygen in the water.

Out-compete Native Species
The alien plant consumes resources faster or takes up space before similar native species do.

Cross-breeding
Alien plant species might genetically mix with native species and change the entire make-up and ecological role of the native plant.

Why Should we care?
•Decrease local Biodiversity
–When foreign plants invade a new area, these species displace or may even harm native species. The foreign plant may cause larger environmental problems, including extinction. •
–Impacts natural resources like water, agriculture, forestry, and fisheries
•It costs lots of money to get rid of foreign species and the seeds/pollen from these plants may impact local food chain and food supply dynamics.


What can be done to stop invaders?
Biological Control
–Using Natural Enemies to keep the invade population growth in check.

• Mechanical Control
–Physically removing or destroying the invaders.
–

What else can be done?

Regulation
–International, Federal, & State Agencies

What can I do?
• Education
–Community Outreach, Public Service Campaigns••

Action Items:
Tell others about Invasive Plant Species and the problems they cause.
Work to promote planting and gardening native plants, flowers, and trees in your neighborhood.
Create a Public Service Annoucement Poster to educate your neighbors and friends about invasive plant species.

•Tell your audience:
–WHO are the players - the name of the invasive plant species.
–WHAT is the problem - the problems caused by invasive species.
–WHY they should care.
–HOW they can help solve the problem.

When you're done, your WANTED poster might look something the one created by one of my students involved with an After-school Program at Normandy Senior High School in St. Louis, Missouri.

Science news: Lizards are dwindling, too.

Lizards join frogs in rapid decline
The precipitous loss of amphibians in recent years has been blamed on habitat loss, global warming, fungal infections, and pesticides.

Urban Parks are great!!

Urban parks an answer to global warming?

Scientists looking at the effect global warming will have on our major cities say a modest increase in the number of urban parks and street trees could offset decades of predicted temperature rises. The University of Manchester study has calculated that a mere 10% increase in the amount of green space in built-up centres would reduce urban surface temperatures by as much as 4°C.
