This article talks about great white sharks potentially preventing and lessening global warming. Marine scientist Rod Connolly from Australia published his research on these sharks. He hypothesizes that predator fish are a key to keeping mangroves, sea grasses and salt marshes intact. Connolly says “reducing the number of large predatory fish through overfishing or deliberate thinning could result in terrible environmental problems and affect how researchers combat climate change.”
This article in my opinion is pretty relevant to marine biology. I think the public should know about this, especially countries that hunt sharks specifically for meat or non-research reasons. I think sharks are scary when you just hear the word shark, however, these creatures are beautiful and a crucial part in the marine environment. This author wrote this article about Great White Sharks to inform readers and the non marine public about how sharks impact the environment, and potentially people. If sharks reduce global warming, people should definitely work a bit harder to protect them, rather than fear them.

The Florida Aquarium is a place that I frequently visited as a child, and still I go often as I am 17. When I have gone previously, I just walked through and looked. I would sometimes read the signs in front of the tanks and try to learn about that animal but I never actually cared enough to actually learn. However, since I have been taking this class, the aquarium was a whole new world.
When our class went on Friday, Mr.Maraghy changed my entire outlook on the aquarium. I had previous knowledge from the material we were taught in class and he was informing us more about the organisms as we walked through. Throughout the aquarium, there was so much I hadn't noticed before. Now, I have more knowledge about marine organisms and marine life, I can look at all of these animals differently. Matthew wrote his research paper on a Goliath grouper, which the aquarium has in captivity. It was really exciting to see an animal a fellow classmate had written about and researched. I really enjoyed this trip to the aquarium much more than any other time I have ever been. I look forward to going with my family and friends and teaching them what Mr.Maraghy has taught me. This article is talking about kelp forests disappearing and nobody could find out why. Finally, people started realizing that the kelp was being eaten by seaweed eating fish. Off the coast of Australia is where this mystery took place. Many species reside in kelp forest, it's a very safe environment to live in. Protection and food all in one. The researchers that were watching over these forest conducted an experiment. They placed kelp on the sea floor and watched what fish ate at it. The rabbit fish and drummer fish were the main predators. The disappearance of the kelp was starting to become an issue. The home of many organisms was being taken away, as was the food and nutrients other organisms needed to survive off of. The researchers kept watch over the kelp forests to make sure they weren't going to die off. The public doesn't know about this because it's not that relevant to humans on land, rather organisms in the ocean. I enjoyed reading this article since we talked about kelp forests in class. The kelp also release oxygen for us humans to breathe in. https://www.sciencedaily.com/releases/2016/11/161114162335.htm bing.com
Sharks are a fish that breathe through gills on their very moist skin. The pacific spiny dogfish is species of sharks found in the northern pacific. These sharks moisten their skin using recycled ammonia. The sharks recycle the ammonia through their gills and turn it into nearly a third if the nitrogen needed. Researchers at University of British Columbia researched these sharks discovering why they intake so much ammonia. They feed on protein to restore urea in their tissue, and apparently intake ammonia for moist skin. Zoologist Chris Wood found out they intake ammonia through a biological process. I feel like this research isn't very important. Sharks having moist skin isn't necessarily a big problem in society. Personally, I think researchers should spend their money on more important topics or issues in the marine world. If scientists continue this study, I think they should expand their research to multiple species of sharks and connect them. The significance of this research is not very significant. It's interesting how the sharks intake ammonia through a process rather than just inhaling it through their gills. In class we talk about gasses in the ocean and other chemicals, such as ammonia. These sharks are moistening their skin with chemicals not usually looked upon as beneficial. I don't think this is a problem, unless the intake of ammonia becomes too high at the point of which it will turn toxic and harmful to the animals. I'm not sure if the public knows about this. I have never heard of this species of sharks until I read this article. https://www.sciencedaily.com/releases/2016/10/161028085823.htm https://www.bing.com/images/Emily Tripp wrote this article about sensors that can go as deep as 330 feet below the water surface. NOAA, National Oceanic and Atmospheric, scientists will exploit about 20 buoys nearly 300 miles off the coast of california. Researchers are curious about beaked whales and their decline of population from 10,700, to 7,500. These buoys will be at sea for 20 days, in search of information pertaining to these deep sea creatures. I feel like this article is an important step to conducting more research about the deep sea and what lives there. If these buoys can record information about beaked whales, they can record information about unknown organisms. In class, we talk about different depths of the ocean and what tools/vehicles are used for research. We can be taught about these buoys and the make of them, the maximum depth they could reach, also how they are operated. I found it interesting how just a normal looking buoy that anyone could see in the ocean, could be such a monumental step in deep sea research! I don't understand how these buoys record information, do they have a camera or recording device? I think these buoys will be a small advancement in deep sea research, however Idon't think this will be Nobel Prize winning research. Article Source: Tripp, Emily.

This article is about research performed by Professor Justin Marshall and his team from the Sensory Neurobiology Lab at the Queensland Brain Institute. This team researched anemonefish and their environments, coral reefs. Their theory was “coral reefs are the most colorful environments in the world, and this become more clear that the reef fish see colors we can't”. Reef fish are blue-biased, meaning the colors are slightly more blue to the fish than to us, creating different colors for them to see.
I feel this research is not very crucial, but it is important in understanding an anemonefish daily life. Seeing other colors could affect how the fish observe their prey and their habitats. If the colors are initially blue, or more blue than humans see, the anemonefish could have a better way of moving along and spotting different organisms in the ocean. This research isn't as important in relevance to other said research being done in the marine biology world. This is relevant to class in a way of teaching us students the color spectrum. If us humans only see red, orange, yellow, green, blue, indigo, and violet, and anemonefish see any more than that, I think it is relevant in teaching us different colors. I don't think the public knows about this, only because anemonefish aren't a big part of today's society. Besides the movie Nemo, not many people care about anemonefish. I don't think this is a problem, yet a benefit. These anemonefish can see certain colors that could benefit them on a daily basis. https://www.sciencedaily.com/releases/2016/09/160921160343.htm |
