Amphibian Decline & Deformities

Please write a two to three paragraphs summarizing the article on amphibian decline & deformities. Specifically address the four causes of this phenomenon and any interesting supporting facts.

The underground man

Who is the ‘underground man’? What are your first impressions of him?

The underground man seems very curious to me. So far, he known to be a middle aged man with a liver problem which he doesn't pay attention to. I think the impression he is giving off when he refuses to go to the doctor is a bit childesh. He does go to the doctor and understands he has had this disease for 20 years but yet will not get it fixed. He wants people to think he is a tough guy who can deal with problems, but really can't. He seems to be alienated from the people and things surrounding him. He gives off the feeling that he is better than everyone and his ideas are much more better than the people around him. He also seems very indecisive about his decisions. He know that he is very educated and has knowledge which might make him think he is better than other people.

Sea Cucumbers....and torn tendons?

In class, we are currently studying Phylum Echinodermata--sea stars, sea urchins, sea cucumbers, sand dollars, etc. Echinoderms have several purposes within their specific ecosystems; however, why are they such a hot topic in science, especially in the medical field? The answer lies in their extraordinary ability to regenerate lost or damaged limbs, a feat attributed to catch connective tissue. This white, fiber-like connective tissue is unique to enchinoderms, and the sea cucumber has proven to be especially easy in to observe this feature as it lacks an endoskeleton. Check out the article below on how scientists are hypothesizing sea cucumbers could work miracles in the feature for people with tendon injuries.

Insect Mania!

Insects are one of the oldest and most highly adaptable organisms on the planet. With the current climate changes (higher temperatures, seasonal shifts, etc.), how do you think the insect populations will be affected? Provide two examples in your answer--the first, describe an organism that may benefit from these effects; the second, describe an organism or situation that could be detrimental.

Animal-Like Protists

Please read the short articles on edline. Notice that there are three different articles and you should choose yours according to your last name. Summarize the article and provide details on what you found interesting and any important concepts related to protist biology. Why do we study protists in zoology (if they are not animals)?

Green Sea Slug

It's really interesting that an animal can steal genes from a plant and keep them for the duration of its entire life. The fact that a slug can manufacture chlorophyll is an amazing step in evolution for these animals. I didn't know that genes could flow across kingdoms. This slug is different from other slugs because it doesn't need other nutrients to keep its new talent working, it can just sunbathe and this is all very new. We would have to make a new way to class these plant animal hybrids because they are the first of their kind. This is fascinating that there can be a hybrid between plant an animal but it does make sense from an evolutionary standpoint that an animal would want to be able to never have to eat and just sunbathe.

I thought that this organism was especially interesting because it could be classified many different ways. It is an invertebrate, it is a plant, it is an animal. It has no backbone and it lives in the sea, it looks like a plant, it produces chlorophyll, but it is really a slug. “This could be a fusion of a plant and an animal — that’s just cool,” said invertebrate zoologist John Zardus of The Citadel in Charleston, S.C.

I thought that these were really interesting because they could be classified so many different ways; it depends on what the most important kingdom to classify something under is.

In my opinion, there should be a classification for things that fall under more than one category. I think that there should be special classification an 7^th group for something that fits into more than one group.

It has adapted its self to produce chlorophyll and blend in with coral and other plants in order for it to be more transparent in its surroundings.

Green Sea Slug--How do we classify it?

Please comment on this post, and write a brief response to the article "Green Sea Slug."
http://www.wired.com/wiredscience/2010/01/green-sea-slug/

Think about this organism--what strikes you as interesting? What adaptations does it have? How is it different from other organisms with similar abilities? Where in the world do we group this organism using our current 6 Kingdom taxonomic system? What shared traits does it have with other organisms and what characters are derived?

You do not have to answer all these questions, but be thoughtful and creative in your response, demonstrating your knowledge of concepts used in class. Also, check out your classmates posts and build upon their comments.

Zoology Zone Welcomes a New Year, a New Class

The Fall 2009 class finished the year strong and is currently spreading their newly acquired knowledge of animal diversity. It was a wonderful first semester for the Zoology Class, and I would like to thank the 12 brave students who made this class fun to teach everyday. I would also like to thank them for providing critical feedback and suggestions in order to improve the success of the class for the benefit of future students.

With that...Spring 2010 semester is quickly approaching! An entire new class of soon-to-be zoologist will be entering the Zoology Zone and writing our weekly blog sections. Keep your eyes peeled for their first entries as we follow the recent trends in animal science.

Comment on Bird/Dinosaur Article

I thought this article was very interesting and logically laid out. I have always thought that birds and dinosaurs were brothers, but, after reading this article, I find myself convinced that dinosaurs and birds are quite different. As said in the article, "It's really strange that no one realized [how different they are] before."

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.

Zoology goes to the Indy Zoo!

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.

Giant Squid

This giant squid's tentacles have crazy hooks to catch prey.

Carsten Smith: Coral Bleaching

Coral bleaching is a rising problem in today’s oceans, but I feel that the area where coral is most at risk is near the Gulf of Mexico, the coast of Florida, and the Caribbean, and in the waters surrounding East Asia. I think that the coral is most susceptible to coral bleaching around East Asia because of the high levels of pollution coming out of the industrial nations of that area of the world. I feel that the coral in the Caribbean are in danger because of rising water temperature because of global warming, and natural disasters, which can change the depth of water, and physically kill a lot of coral. I feel that although we cannot immediately stop any of these problems now, we can make steps towards the future with stable marine conditions, we can still do our part to replenish the worlds coral populations. I heard earlier this week on the radio that as a science project a man and his daughter tried to breed coral, and now the state of Florida is spending millions of dollars to expand this families “science project” into a major breeding center for the many endangered species of coral, and has proven to actually accelerate the expansion and development of coral to other areas other than the areas where they are planted and can definitely help replenish the falling number of coral, which can even keep future species of coral from going extinct.

Coral Bleaching

I think that coral bleaching would be more popular near the equator in the warm waters. I think this because corals become bleached when the zooanthellae can't protect the corals anymore from the UV rays. Also i think coral bleaching would be more common in the shallower waters since they would be near the surface which gets the most sunlight again causing the corals to die. A way humans could help with coral bleaching is not polluting the waters such as dumping oil in the water. Another thing would be to help stop global warming because this plays a big part in helping the corals survive. Without the corals, many organisms such as the zooanthellae would die out because they wouldn't have the corals to live off of.
