Gopher tortoise are ectotherms that can mostly be found in the southeastern parts of the United States because of the sunnier weather in that area. They are known for digging burrows underground that can be 12 meters long and 3 meters deep. Many species live with the gopher tortoise in the burrows that they make for protection against fire, predators and also for warmth during the cold nights and to stay cool in the hot days. Species that lives with the gopher tortoise includes: rabbits, burrowing owls, mouse, frogs and many different types of small insects. Since the gopher tortoise are considered as threatened species, it has become very important to protect them as the burrows that they dig helps to increase the diversity of species in the area. There are also many causes that has led to them becoming threatened such as their low reproduction rate, loss of habitat due to urbanization and the predators that prey on their eggs and young hatchlings. Because the gopher tortoise can only lay up to 8 eggs in one year, protecting the eggs from predators like coyotes or raccoons is crucial for their future population. Also, protecting the young hatchlings is just as important because they are still …show more content…
However, it is also just as important to learn more about their predators because they are one of the main causes for the decrease of the tortoise population. That is why we have designed an experiment to find out when predators come out to hunt for the eggs and young hatchlings. Our prediction is that predators of the gopher tortoise will tend to come hunt more at night since gopher tortoise are less active at night time. Therefore, if gopher tortoise are resting in their burrows then predators will come out to find the eggs. The independent variable of this study are the predators. The dependent variables will be day and night. This study will be conducted through observations from
Isle Royal is located fifty-six miles north of Michigan’s Keweenaw Peninsula. It is the largest wilderness area in Michigan (USNPS, 2014). The island is surrounded by Lake Superior, which creates a cooler temperature. This results in arctic plant species growth on the island. There are only eighteen mammal species present on the island because most mammals cannot make the trip across the frozen great lake (USNPS, 2014). The need for an ice bridge is not the only environmental factor that is stopping the migration of animals; there is also the severe cold, and also wind and fog (Vucetich, 2012). Some species such as caribou and coyote have found the island to be too intense and have gone extinct (Vucetich, 2012). Due to the harsh weather and isolation of the island, humans have never regularly lived on the island (Vucetich, 2012). Some of species that are present such as the red squirrel are becoming their own subspecies due to its separation from the mainland (USNPS, 2014). The isolation of Isle Royal is what makes it a great place to conduct research, it has very low human interaction and the species that are on the island will have been and continue to be isolated from the mainland.
Josh Boylan, Crawford County Coon Club President states, “Raccoons are one of the smartest animals”. As a veteran coon hunter, he has encountered numerous amounts of raccoon. Not only does he say that raccoons are one of the smartest, he also states they are one of the meanest animals that he has encountered in close quarters, “They will attack anything, they may get there ass kicked in some of the battles, but they will give it hell.”

The processes of predation affect virtually every species to some degree or another. Predation can be defined as when members of one species eat (and/or kill) those of another species. The specific type of predation between wolves and large ungulates involves carnivores preying on herbivores. Predation can have many possible effects on the interrelations of populations. To draw any correlations between the effects of these predator-prey interactions requires studies of a long duration, and statistical analysis of large data sets representative of the populations as a whole.
Curiously, the Atlantic Puffin is also known for occupying the empty burrows of rabbits. Although this habitat is potentially more dangerous, many puffins survive in this nesting situation. Many of these islands are barren and have little or no terrestrial predators.
Loggerhead turtles are becoming endangered more and more often. Not many people understand the dangers that these turtles are in, especially when the females are nesting. Nesting takes an important role in the lives of these turtles and is an amazing process that occurs during the season. Unfortunately, many factors disturb the process of these hatching eggs. This paper explains these factors in depth to educate the audience about the dangers involved in loggerhead nesting. Light pollution, natural disasters, and predators are described and explained as to why they affect the process of nesting. Many organizations are trying to share their knowledge on these loggerhead-nesting dangers with people and are trying to help keep the loggerheads alive.
It’s hard to believe in 2015 that there are parts of the world yet to be explored, but a new species of monkey discovered in Peru demonstrates just how much of planet earth we still haven’t seen. This discovery sheds light on not only what exists untouched in the most remote parts of the World, but also what we may lose without ever knowing thanks to human development. This entire species and others like it have the potential to disappear forever without ever being discovered if conservation efforts are not enhanced.

1These two populations are different species because they have different capabilities of performing in nature. For example there is behavioral isolation. My evidence for that is that in the data, it states that the average time spent in courtship display for the St. Kitts rodent is 12.6 seconds. While the courtship display for the Nevis Rodent is 21.3. You can see that there is a major difference in the way that they behave. Also there is another type of isolation which is gametic isolation. There is gametic isolation because the average gestation time for St. Kitts rodent is 29.3 days. The average gestation for the Nevis rodent is 42.7 days. Therefore a sperm from St. Kitts rodent wouldn’t survive in the reproductive tract of the Nevis rodent. It wouldn’t survive because it wouldn’t develop properly and is not accustomed to its environment. There is also another type of isolation happening with the rodents of St. Kitts. This type of isolation is called temporal isolation. There is temporal isolation because the article states, “the reproductive seasons are being delayed by up to one year.” This is talking about that the rodents are having a hard time finding mates therefore, their reproductive season is being delayed. Also in the article it states, “In the 240 attempts to bring a Nevis animal into the St. Kitts population, you are unable to observe a single successful reproductive event.” The rodents are mechanically isolated, because if you can’t have a reproductive event, there reproductive organs might not be matching with one another. Their appearance might look identical but they are genetically different.
Origin - The Maine Coon is a natural breed, however currently the actual origin of the Main Coon is still underway. The "myth" of the Maine Coon coming about from the mating of raccoon and domestic cat is amongst the most popular. Although this is genetically and scientifically impossible to achieve, it first came about to be believed due to its unique brown raccoon-like markings and big bushy tail. "Maine Shags" were the name given to those that had markings any other color besides the brown coat. Theory of Maine Coons coming about from Viking's bringing these animals over into North America has been one of many popular theories. However, the most common theory is that of Marie Antoinette. Many believe when she tried to escape to North America, but did not succeed, she had left her long-haired cat on board, which then came to North America and bred
Introduction Caretta caretta, otherwise known as the Loggerhead Sea Turtle, is an oceanic turtle that exist throughout the globe. They are circumtropical species (LeBlanc et al. 2014) meaning they are distributed throughout temperate and tropical ocean regions, but most abundant species are found in the United States coastal range. Loggerheads largest nesting aggregations in the Atlantic are found along the southeastern United States coastal range where about 80% of all nesting occurs and 90% of all hatchlings are produced (Abecassis et al. 2013).
Both the snow leopard and the green turtle are classified as endangered under the IUCN red list with decreasing population trends. Both live in very different habita...
The Rodrigues giant tortoises were an endemic species of tortoise found on the island of Rodrigues, Republic of Mauritius. There were two types; the Saddle-backed Rodrigues Giant Tortoise and the Domed Rodrigues Giant Tortoise. The former was greater in size compared to the latter and weighed up to 60 kilograms, this kind is a Saddleback, meaning its shell had a notch at the front, which allowed it to elevate its head more to reach food from higher places. The latter had a size of about 42 centimeters and weighed around 12 kilograms, this type had a domed shell that tilted straightly towards the ground, which made foraging limited to low areas.
