The importance of behavioral adaptations in turtles to thermoregulation and survival Katherine Whitehead Biology 301 Lab 7/15/13 Abstract Thermoregulation is necessary for ectotherms to survive. One important mechanism for thermoregulation seen in turtles is the ability to migrate between land and water habitats. This mechanism was studied using I-button data loggers placed inside marshmallow peeps to record temperatures in two different microhabitats; one in a stream and the other on the

have done studies on the population genetics of the green sea turtle. Through their DNA research‚ it was discovered that human impact has drastically reduced the genetic diversity within the green sea turtle population. In the future‚ this can prevent the reptiles from adapting and evolving because the ones that are left are extremely alike. A natural disaster or a catastrophic event can greatly diminish the number of living green sea turtles‚ triggering their approaching extinction. Even in the population

Sea turtles are threatened and endangered throughout their natural range due to various anthropogenic interferences‚ such as poaching and habitat destruction (World… c2016). Sea turtles provide many ecological benefits‚ such as acting as distributors of nutrients and sculptors of both terrestrial and marine substrate (Mancini et al. 2011). However‚ global climate change is threatening sea turtle populations’ ability to continue to provide these benefits (Mancini et al. 2011). Beach habitat loss due

The Loggerhead Sea Turtle (Caretta caretta) is an aquatic reptile‚ which are given their name for their large skull and powerful jaws. Adults can weigh anywhere from 155 and 375 pounds‚ making them one of the largest hard-shelled sea turtles in the world. Their shells are mostly brown with yellowish spots and yellow underbellies. As many sea turtles do‚ females come ashore during summer to nest. Once hatched‚ juvenile turtles make their way to the ocean. From nest to shore is one of the most dangerous

Aral Sea The Aral Sea was once the fourth largest inland sea in the world. About‚ a million years ago from now the northwestern part of Uzbekistan and southern Kazakhstan were covered by a massive inland sea. This sea was formed when all the waters retreated from a big land; they left a broad plain that contained highly saline soil. Due to the retreating of water many ancient remains were disappeared. The only remnant that remained was a big inland sea which was the Aral Sea. The Aral Sea was an

Sea anemones are members of the Phylum Cnidarian. The cnidarians include the anemones‚ jellyfish‚ coral‚ Portuguese man-of-war and hydroids. Their characteristics include a soft body with two tissue layers arranged around a central gut cavity. A ring of tentacles surrounds a central mouth‚ and the tentacles endure stinging cells which contain nematocysts used to capture food and for defense. ("Marine Life Profile: Sea Anemones”) The two basic body forms among the cnidarians are the polyp‚ which looks

13 Cause and Effect Essay. The Aral Sea disaster. The Aral Sea disaster is one of ecological disasters that effect terribly on our life. It was fourth largest lake in the world‚ but nowadays 80 per cent of water disappeared. The main reason why the Aral Sea has shrunk so dramatically is because water from the rivers flowing to it has been diverted for irrigation. The Aral Sea basin is fed by the Syr Darya and Amu Darya Rivers‚ which flow directly into the sea. Other rivers feeding the basin are

#1: “The Salton Sea” Summary In 1905 heavy rain falls and snowmelt overfilled the Colorado River. In result the water poured over the headgates in to Alamo Canal. The flood soon reached an Imperial Valley dike and in a period of two years the entire process of the Colorado River flood would soon create the Salton Sea. The Salton Sea is located at the Colorado Desert in Southern California laying below sea level and said to be the largest lake in California. The creation of the sea made Salton City

Sea urchins are members of the phylum Echinodermata‚ which also includes sea stars‚ sea cucumbers‚ brittle stars‚ and crinoids. Like other echinoderms‚ they have five-fold symmetry (called pentamerism) and move by means of hundreds of tiny‚ transparent‚ adhesive "tube feet". The symmetry is not obvious in the living animal‚ but is easily visible in the dried test. Echinodermate means "spiny skin" in Greek. Specifically‚ the term "sea urchin" refers to the "regular echinoids"‚ which are symmetrical

Heldt Mr. Bender English 10000 8 May 2012 The Sea After reading The Old Man and the Sea‚ written by Ernest Hemingway‚ I found the most interesting part of the book to be the sea itself. One can almost consider the sea another character‚ due to the vital role it plays in the short novella. The sea provides a glimpse at Santiago’s knowledge and experience that he has acquired throughout the course of his life. As well as the sea is used as a metaphor to the literary community‚ if one
