Comment on Bird/Dinosaur Article
The article explains that, for many years, birds were thought to have been the descendants of theropod dinosaurs. Recent studies and findings, however, debunk this theory. Birds have a fixed femur and walk exclusively with their knees, unlike any other animal. They have this unique bone structure so that their lungs, while flying, do not collapse under the strain that flying can cause. Dinosaurs had moveable femurs and walked using a combination of their femur and knees. Birds and dinosaurs have been linked for so long because of similarities perceived in their lung structure, but the structures surrounding dinosaur lungs and bird lungs are, in fact, entirely different. Furthermore, birds seem to appear earlier in the fossil record than dinosaurs, so birds couldn’t be descended from dinosaurs. It is more likely that birds and dinosaurs shared a common ancestor, as opposed to being directly related.

Bird Mania!!
Science is happening all around us, every day. Sometimes, however, the current science news doesn't make it into our textbooks for over 3 years or more! Read this article from June 2009 on the current thoughts of bird evolution. Quite contradictory to the theories we just learned and discussed in class isn't it? Be prepared to talk about this in class on Friday, and feel free to comment below on whether you agree, are skeptical, etc.

Above, the zoology class is pictured with Tombi, one of the Indianapolis Zoo's African elephants. Aside from learning about Project Elephant and the training and research conducted on artificial insemination, students also explored the Oceans Biome with Project Dogshark and the Desert Biome with the Iguana Project.

Carsten Smith: Coral Bleaching

Coral Bleaching
Tuesday, September 29, 2009
Coral Bleaching
I think that the coral reefs around the equator and in tropical seas are most susceptible by coral bleaching. These tropical seas contain the corals that form a symbiotic relationship with the algae, and depend on this relationship to live. This area is most affected by coral bleaching due to the numerous problems that can occur that will ‘stress’ the coral and make them get rid of their algae partners, such as rising temperatures or changes in water make-up. Radiation can also greatly affect these corals, and events such as water levels dropping can cause radiation to hit corals that previously were submerged. There are several ways humans can help to prevent coral bleaching. Keeping the oceans and seas clean is one way that is most valuable. Chemical and oil spills damage corals and surrounding life, and can alter the temperature and chemical make-up of the ocean waters causing coral bleaching. Also monitoring and helping to combat global warming is another prevention for coral bleaching. Global warming increase the temperature at which corals live in, and will cause them to expel the algae living on them, opening them up to radiation and coral bleaching. Being a caretaker for the environment will help to prevent coral bleaching from continuing or happening in the seas.

Coral Bleaching
After reading the article, I was surprised to find that the Caribbean was struggling with coral bleaching issues but this makes sense. The Caribbean is close to the equator and has a large coral population. I was especially shocked to read that 90% of the coral in some areas is bleached.

Coral Bleaching
Coral Bleaching is the result of algae not properly doing there job when interacting with the reef corals. This causes a problem because then the corals will not be able to photosynthesize or be protected from the UV rays without the algae. Because of this, I believe most of corals that are being affected by bleaching would be in warm climates, such as near the equator, and they would most likely be in shallower water. This is because the sun will make them much more vulnerable to the UV ways when they are in the warmer climate and when they do not have the water’s protection. This is a problem because bleaching will lead to the coral reefs dying, which will also lead to many organisms losing their habitat. Humans must find a way to solve this problem because of this. For instance, they could pass laws to not allow boats on the waters where coral reefs that are in danger. This will help the coral reefs because by boating, they will only be exposed to more problems, such as polluting. If a community does not allow boating, it will aid the coral reefs by not creating other problems for them as well as bleaching.

TURTLES
I think that Veolia Indianapolis Water Company is so stupid. Their idea is not going to really have that big of an impact on the canal but it will have a huge impact for all its wild life that call it a home. They will be killing a mass amount of turtles and other animals such as muskrats. They came out and only told us about the muskrats because naturally the reaction you see on a persons face when they hear muskrat is not usually one of satisfaction, they think they are pests. However, people found out about all the turtles this process would be killing. People LOVE turtles, I love turtles. They are not doing any harm why would be want them to disappear. Many people were outraged by what would happen to the turtles, and how they would no longer be able to see them in their everyday life, which is fascinating, I love turtles, and what they are doing is just absolutely wrong. Zoology plays a big role in this because of how we can see what environment these animals are better suited for, and how they reproduce. If this were to occur then the population numbers in turtles would drop significantly until they are completely gone.

Reponse to the mistreatment of environment along the canal.
Tenacious Turtle Troubles.
I Like Turtles
By putting up another wall or adding material to help with erosion is going to harm thousands of baby turtles. The environment of the turtles should not be manipulated, because it could really hurt them and put their species in danger. I believe that the water company is in the wrong.
I don’t think that there should be any more investigation to prove that it will harm the population of turtles, because I know it will. I think there should be more investigation and researching for an alternative method. One quote was that they should try to find a more environmental friendly way to go about this, and that is absolutely correct. I feel as if they just thought of the best idea to benefit their company, rather than look at it from a point of view of the environment.
The section about the DNR was very interesting too. Veolia Indianapolis Water is concerned about letting the DNR know about muskrats, but what they are doing won’t kill the muskrats. I feel like they are just trying to put the fact that they will be killing hundreds of turtles under the rug. It’s stupid if they thought that no one would notice.
This population of turtles has been living in the canal for several years, and Veolia Indianapolis Water has no right to get rid of them.
It is important to study zoology because in an example like this, people always make decisions based on what they want, or what can better them. Humans are always thinking about humans. It is important to think about other things, like these turtles. It’s important to think of the environment around us and what inhabits it before we make a decision to change it. If this project is permitted, it would cause the turtle population to go down by a lot, because none of the baby turtles would be able to survive or join the rest of the population.

Canal Project
I personally feel that the turtles should come first in this situation. I understand that water is extremely important, but there are other ways to get water and there are only so many places where turtles can live. I honestly don’t know what I would do if I had to make a decision about this. I would probably find a way to fix what I needed without making a huge change to the turtle population.
The zoology from this situation plays a large role. The water people need to understand the life of a turtle and how important they are to our environment. It would be helpful for them to know more about the history of turtles, so they would have an understanding of why people are so passionate about having them in the canal.
The population of turtles would go down if this project were put through. I don’t think that there would be specific traits that would be passed on because in this case it is luck of the draw. It is not targeting any specific type of turtle; the project would simply hurt that turtles that interfere with the project. The turtles that are not affected are a random bunch of turtles, so there is not one specific trait that would save them because it all depends on the location of the nests.

Veolia Indianapolis Water Construction
After reading this article I was disgusted with the Veolia Indianapolis Water Company’s actions in terms of ‘restoring’ the canal downtown. By taking such careless actions as to not take into account the repercussions their construction on the canal would bring onto the natural wildlife and environment that has developed in and around the canal, the company reflects its self-interest and purely financial reasons for this hasty construction. That, and the fact that the company has not even applied for a DNR permit for construction in the canal. Careful maintenance and construction can be done in an environmentally efficient and green manner, but apparently the company has no regard for this. More investigation is needed, and more care and attention needs to be placed on the turtles and other wildlife and botanical life along the canal. If I were handling this project, I would make sure to not move ahead with the project until all effects and possibilities in relation to the wildlife and ecology in the canal would be analyzed. And, once I understood the effects, I would make sure that the project would only restore the parts of the canal that needed restoration or construction; I would also outline and input a plan that fits with the construction codes of a green, environmentally safe project. The preservation of life and ecology would be my priority. The study of zoology is very important in this situation as it would allow the understanding of what the effects of this project could have on population such as the turtles, muskrats, etc. in the canal, as well as how they would adjust in terms of this situation. If this project is permitted, which I hope not, then the effects upon many of the populations of animals living in the canal would be dire. The company plans to remove large stretches of bushes and trees growing along the canal; by doing so would eliminate the environment around the canal. Construction would also change the habitat that many of the turtle species have developed to, and the population would have to adapt to the new changes in their environment in order to survive as before. They would have to develop new nest behaviors as well, as the locations as to where they were able to lay their eggs will be completely covered y the new construction.

Canal Conflict
In Our Own Backyards...Conflict along the Indy Canal: Human drinking water or Turtle nesting site, who wins?
http://www.indystar.com/apps/pbcs.dll/article?AID=2009908310347
Read the following article. Please write a short response that includes the following points:
1.) Your personal feelings on the issue. Is the water company right? Turtles right? More investigation needed? How would you handle it if you were the water company in charge of the project?
2.) Identify how the study of zoology is important in this real-life situation.
3.) If the project is permitted, would could be the future impact on the turtle population along the canal? Do you think that the population would be selected for specific traits due to changes in the environment? If so, what types of traits might these be?

Natural Selection at work...even today!
An article released in Science Daily last week describes the work of two Harvard scientists who studied the effect natural selection has had on the coloration of deer mice living in the Nebraska Sand Dunes. Check it out and make sure that you can use the tenants of natural selection to explain how this change in coloration occurred in this particular population...apply your knowledge! Natural selection is occurring even today on organisms. :)

Evolutionary Processes
Like Caleb said, one of the professors said they were going to take on the perspectives of earlier naturalists. In class the other day, we talked about the classical approach and the modern approach. The classical approach involved studying an animal's morphology. The modern approach involved a more encompassing view of evolutionary relationships.
This was interesting because the article talked about combining ecological and evolutionary findings using how evolution has affected a species. Also, they would be able to discover things about certain communities that caused them to be how they are now.
I really like what Erin Bortz pointed out. At the end of the article it said that this would help save many habitats from being completely destroyed.This was a good point about the new research because it is important to help and preserve the environment because we are all connected.

Evolutionary Process
Since zoology is the study of animals, it is necessary that they have a proper environment to live in. Ecology and evolutionary process play a large role in how animals live. In order for animals to survive, they need plants and then evolution allows a species to adapt to their environment. Animals would not be able to survive without ecology and evolution and it is very interesting that there are so many studies taking place discussing these topics together.

Carsten Smith: Evolutionary Process
At the start of reading the article I was a little confused by what the article was saying. I interpreted it, as being that this group of scientists was starting to study how multiple species of organisms can co-exist while maintaining their independence from other species. It said that this research could help with managing and restoring the earths “flora and fauna”, because so much of it has been destroyed by foresting, expanding cities, and many other things
Welcome!
This blog is a tool utilized by our class to help keep us connected with current events in animal science...and to have a little fun viewing photos, videos, or articles on the fun and wacky animals we may discover along the way. I encourage you all to post at any time, as long as material is in some way relevant to zoology. In this way, not only will you be responding to articles I assign, but you'll also be taking charge of your zoology education!
For Friday, please read the following article and write a short response on how the combination of ecological and evolutionary perspectives is strengthening our views of zoology.
