AMPHIOXUS

This is a great abstract about AMPHIOXUS that I retrieved from the International Journal of Biological Studies online - -  http://www.biolsci.org/v02p0030.htm

AMPHIOXUS:
The cephalochordate amphioxus occupies a central place in evolutionary thoughts to the origin of Vertebrates. With a prototypical vertebrate-like body plan and a preduplicative genome, the friendly lancelet seems to be in morphological and genetic motionless since its separation from the major branch of evolution that eventually ended up in our corner in the Animal Kingdom. This makes it an ideal model system with which, with the current development of genomic and experimental tools, an Evo-Devo approach to the understanding of the origin of vertebrates looks proper, reliable, and excitingly promising.

The photo below is a picture of Amphioxus. Not the cutest specimens you want to see. They remind me of baby corn, or a fishing Lure. It is amazing to see these types of animals! In class we are learning about the evolution of single cell to multi-cell organisms. It is fascinating to see that this is one of the first vertebrate animals!

LAB #9 - MACON DOG PARK



This is a picture of me and our Toy Poodle SCOOBY :) He is a wonderful part of our family :)....Scooby loooves to play, cuddle, chase birds, squirrels, and eat the pecans in our yard :)...He loves running, and chasing his Blue Frisbee, so we love to take him on walks! Which brings me to today's Lab Entry:

Today was a fun lab. We took a short walk over to the Macon Dog Park.
It is a fun place where dogs can get great exercise, enjoy the outdoors, and even socialize with other dogs. It is also a good place for the community to get together. This sets up a great chance for communities to become closer, form friendships, and enjoy their outdoor community in a safe and inviting way.

You do have to keep in mind the few negatives about having a dog park, though. Because there is a constant influx of different dogs congregated in a restricted area, the chance for disease is always present. Bacteria, viruses and other maladies can affect young puppies, older dogs, and sometimes even humans. Of course, much of this can be contained if the community takes good care of the park, keeping it clean and free of animal waste each day.

The Macon dog park has the Vineville Branch creek that runs through it. This creek eventually runs to Ocmulgee River. Because this creek is in an Urban area, it is called an "Urban Creek".  Urban creeks are a combination of water run-off (Rain) and natural water. Because they are running through urban areas, they tend to have a higher concentration of bacteria in the water. We took multiple samples of the creek at different areas. Bacteria did grow in the cultures Dr. Rood had. It was a high concentration of fecal bacteria....yuck!!!....
Well, other than that bit of TMI - the lab was very informative, and maybe when we are in the area, we will bring Scooby to the park to play and meet new friends!

LAB #7 - Hititchi Experimental Forest


I love the forest and I love hiking. Here is one of my favorite pictures I saw on the Internet.! Well, our field trip was not to THIS forest, but the one we went to was still very nice. We went to HITCHITI Experimental Forest. This field trip was a lot of fun, but definitely tiring! One great thing about the day was the weather - it was perfect!!! :)

Here is a brief background on the Experimental forest, and below that - some pictures I took during the hike!
Here is a Picture I took when we first started hiking:


BACKGROUND ON FOREST:

The Brender Demonstration Forest also known as the Hitchiti Experimental Forest occupies 4,735 acres of land in Jones County, Georgia about 18 miles northeast of Macon at longitude 83 42'30 W., Latitude 33 1'30 N. It lies on the east bank of the Ocmulgee River in the lower piedmont. The areas first known inhabitants were the Hitchiti Indians. They used fire to clear land for planting and to herd game animals during hunts. Through time, timber and cotton were the area’s primary crops early in the twentieth century. However, cotton was short-lived when the boll weevil and an agricultural depression struck. In 1946 the Federal Government established the Hitchiti Experimental Forest that now makes up the Brender Demonstration Forest. Today the Forest is an active research facility of the USDA Forest Service Southern Research Station.

Some of the subjects now under study or demonstration on the Forest include:
  • The effects of varying intensities of site preparation on survival and growth of loblolly pine
  • Effects of prescribed fire under mature loblolly pine
  • Interplanting of Loblolly Pine
  • Precommercial thinning of natural Loblolly Pine
  • Natural regeneration systems for loblolly pine in the lower Piedmont
  • Comparison of Winter & Summer prescribed fires
  • Demonstration of methods of site preparation before planting Pine
  • Methods for maintaining red-cockaded woodpecker habitat and endangered bird species
  • Effects of improper planting of pine seedlings
  • Planting of mountain variety of Longleaf in Piedmont of Georgia
  • Forest insects & diseases
  • Wildlife plantings on utility line
  • Proper logging road construction
TREE HUGGING: 
Dr. Rood had us hug a tree during the hike. Here are the pictures of me, as well as 3 other class mates "hugging" a tree:
 
me, hugging a tree :)





















TREE-PLAYING:
As usual, some of my classmates, took the Tree to a new level, not only hugging it, but climbing it :)

A COOL TREE:
Here is a picture of a tree, with Exposed Tree Roots. We surmised that it was in soil, but perhaps water moved the soil/dirt away, and left the tree growing with exposed roots:

Here is the CREEK that we hiked to! FALLS CREEK. It was very pretty, and scenic. Two classmates fell in the creek trying to cross over...sorry I did not get a pic of that!!!


WILD GINGER PLANT:
Along the trail, Dr. Rood pointed out WILD GINGER plant. Here is a photo of it:


Wild ginger (Asarum canadense) is a low growing native perennial about 6 to 12 inches high that sometimes is hidden under fallen leaves. Popular with pioneers and Native Americans.Pioneers dried and pulverized the root of wild ginger and used it as a spice or as a cure for whooping cough. Native Americans also used the ginger for a variety of ailments including heart pain and heart arrhythmia. A root tea was used for indigestion, cough, cold, cramps, throat ailments, and nervous conditions. Roots were steeped by the Meskwakis and applied to the ear to relieve ear ailments.

LAB #6 - JACKSON SPRINGS/The Great Rock Expedition

Jackson Springs Park is located in Macon, Georgia. It is a beautiful city park. Our lab was to learn about and discuss the different types of rocks/minerals that are present in this area, and of course, in the park. First, we surveyed the area and talked about the plant life there, especially near the creek. We also identified some trees (sycamore, Mulberry, dogwood and hickory trees. We also took a look at how the plant life changed as it got closer and closer to the creek. First grass, then moving closer to the water - moss, and algae in the water. We even saw a cute little baby turtle :)

We went over to the creek and played with rocks! Here are a few pics I took of the minerals and rocks we saw.
FELDSPAR: a mineral









QUARTZ - unbroken; and broken examples










SANDSTONE Sedimentary Rock. Sedimentary rocks are formed when dirt, gravel, sand are pushed down together, and the pressure over time causes them to fuse together to become Sedimentary rock








We also found GRANITE Rock - Granite is a rock that is formed by three minerals: Quartz, Feldspar, and Hornblende:









We found GNEISS - which is a Metamorphic rock: A rock that is formed when rocks, minerals or both is exposed to pressure and heat, which causes the chemical structure of the rock to change









I really enjoyed this lab, and learned more about rocks!. I have always liked collecting rocks when I go hiking, or just if I see a really cool looking rock. Now, when I collect, I will try my best to identify it!!! :)

LAKE INTEREST - Lake Erie

I must admit that I never really thought about having an interest in Lakes. Since I was born and raised in Cleveland, Ohio, I immediately thought of Lake Erie. When I was growing up, my god-parents used to take me and my little brother on Lake Erie to fish. My god-father hand made our fishing rods, which I always thought was really cool! I think I did catch a few small fish, but it was always alot of fun! My godmother cleaned and cooked the fish that we caught....right now, though, I can't remember what kind of fish we actually caught. In the summers, we used to go swimming in Lake Erie, and there were always many festivals to attend during the summer. My favorite was the July BBQ Rib cook-off! My Uncle Sammy always made the best ribs, and he placed in the top 5 almost every year! :) Of course, at the time I never thought a minute about how Lake Erie was created. So, I thought I'd take the opportunity to read up on my home town lake, and share the most interesting points (at least to me) with you!



1.) LAKE ERIE'S DEMOGRAPHICS:
 In total area, Lake Erie is the 12th largest freshwater lake in the world and the most shallow of the 5 Great Lakes. It is about 210 miles long, 57 miles wide, with a shoreline of approximately 71 miles with a maximum depth of 210'. Because of its shallow depth, the lake warms up sooner in the spring, making it an ideal fishing spot. Lake Erie also freezes sooner in the winter, creating a large moderating climate phenomenon that keeps temperatures, while still cold, just not bitter cold. That little detail makes the area an ideal grape growing region. Ohio's coast is 312 miles,


2.) HOW LAKE ERIE WAS FORMED
Over the ages, numerous ice age glaciers helped carve out the Lake Erie basin. Today you can still massive bedrock that was notched by the weight of tons of ice sliding over it on its way into southern Ohio. When the ice melted, large areas of softer limestone and salt beds had collapsed under the weight of the glaciers that left a shallow depression. As the climate warmed, the glaciers melted forming streams and rivers that flowed into that massive depression as they still do today. For the most part Ohio's rivers flow south except for a line that runs roughly through where the glaciers were the heaviest. From that area the rivers flow north, into the lake. It is these rivers that help maintain the water levels of the lake and provide the spawning grounds for many of the lake's abundant fish. In fact, the southwest section of the lake between the Sandusky and Maumee Rivers has become known as the walleye capital of the world.



3.) CEDAR POINT - MY CHILD HOOD AMUSEMENT PARK
The beaches of a little jut of land just south of Kelley's Island known as Cedar Point also became a popular tourist spot for its pristine beaches. So many tourists were arriving each summer that a proprietor decided to add a few rides for the kids and the amusement park industry had arrived on the shores of Lake Erie, never looking back. We went to Cedar Point every year when I was growing up!!! :) It was such a fun amusement park!!!


4.) HOW LAKE ERIE GOT ITS NAME
When French explorers and traders entered the Great Lakes region in the 1600s, American Indian nations already had given names to the immense bodies of water they lived along. As reports and crude maps filtered back to Europe, these Indian names frequently were combined with names the French thought more appropriate.
Samuel de Champlain drew one of the earliest, still-surviving maps in 1632. Champlain named Lake Erie for an Indian tribe living along its shore. The “Neutrals” were a tribe on Erie’s north shore which had not taken a side in a conflict between the Iroquois and the Hurons. Thus Erie became “La Nation neutre.”
Later, Nicholas Sanson, France’s royal geographer renamed the lake Lac Erie, ou Du Chat after the Erie Indian nation. These were a fierce people famed for wearing the skins of cats, a nation known to the Iroquois League as the “Erielhonan,” or the “long-tails.” To the French, this nation was called the Erie, or “cat people.

This large limestone rock is on the south shore of Kelleys Island just east of downtown. The remains of at least two Native American villages were found very near the rock. Archaeological and historical research suggests that until about 1643 AD, Algonquian-speaking groups affiliated with the "Fire Nation" confederacy populated the Sandusky region. Historical references describe a water route of travel via Lake Ontario to the western basin of Lake Erie, an area rich in beaver pelts. It is assumed it was these pre-historic groups or members of roving bands of Iroquoian peoples (Neutral, Erie, Cat) after 1643 that carved the rock’s markings.
