Saiga Antelopes: Aggregative Calving Behavior

With only two hundred and fifty to three hundred left, the critically endangered Cross River Gorilla roams the African forests while on the brink of extinction (Save Our Species). Africa has many populations of primates that are at the least endangered, and the Cross River Gorilla is the closest to extinction and the least studied due to the rarity of observing them. (Save Our Species). These gorillas are confined to small, mountainous areas that have been separated over and over again by fragmentation, furthermore ruining the needed social aspect of the groups and need for vast land (Imong, I., & Robbins, M.), (Save Our Species) The increased hunting and fragmentation of these Gorilla’s habitats has caused a large problem with how the

[Thesis and preview]: Today I am going to share with you a quick history lesson, talk about where these animals currently roam, and explain several threats that this growing population currently faces.

Explanation and Analysis: There really are a lot of characteristics overlooked when talking about Elephants as a whole species.

Within the Endangered Species Act, the U.S. Fish and Wildlife Service helps watch over and investigate the health of different species. Then, local and national scientist collects data to determine if a species gets put on the Endangered Species list. The main factor to determine the endangerment of a species is if a large percentage of the species’ habitat has been destroyed. Next, note if the animal’s population has been excessively decreasing, threatened by disease, or any terrorized by any predators. Also, record any man-made

There are many wild animals in the world are in danger. The mountain gorillas (Gorilla beringei beringei) are one of the most threatened species in the world that inherited from monkeys (Macaca Fascicularis) and apes (Hominoidea), which was found in Africa and Arabia about 34-24 millions years ago. Mountain gorillas are Animalia, which phylum is Chordata and class of Mammalia. The mountain gorilla is a subspecies of eastern gorilla, which live in two regions in Africa. There are three countries where mountain gorillas live. They are Uganda, Rwanda and Democratic Republic of Congo. According to National geographic, there are about 700 mountain gorillas remaining in the earth and half of them live in a Virunga mountains in central Africa. In average, they live about 35 years; the standing height of a mountain gorilla is between 4-6 feet. They’re weight usually between 300-485 pounds and they are bit larger than other type of gorillas. Mountain gorilla usually live in a group and head of their group is called ‘silverback’ that is an adult male who grow a patch of silver hair on their back and hips. However, when dominant silverback die, the whole group face hard time to regroup themselves. Female gorilla usually becomes sexually mature before male gorilla. At the age of 7-8 female gorillas become sexually active, however they started to breed few years later. On the other hand, male gorilla starts

Conservation of our biodiversity not only demonstrates foresight, it protects the natural resources so vital to our own continued existence. The value of any single species to an ecosystem is immeasurable; the environment will not endure without its species, despite size or niche. These animals are not dispensable. And, they are apt to face extinction in the not too distant future, unless a resolve for their preservation is insisted by the public and enforced by governments internationally.

After completing my major of Environmental Sciences at the University of Notre Dame, I would like to attend graduate school and continue to research mammals in the field. Though I am not completely certain, I may seek to become a professor to teach others that share my passion for conservation of the environment and wildlife, or work for an environmental agency. To become an agent of change in this field, I would like to focus my research on studying the effects of climate change on mammals. Accordingly, I want to aid in preserving these species, especially those that are endangered, to further promote biodiversity conservation.

Genetic diversity is essential for a healthy population, and conservationists believe that the introduction of eight bulls to Addo from the Kruger National Park, will not only increase the diversity of the gene pool but reintroduce a dominant tusk gene (SANParks Media Release, 1). The bulls selected were also not known to be aggressive towards other elephants and humans as park officials did not want to introduce behavior inconsistent with those of the Addo elephants. To ensure that these 8 bulls have a greater chance of becoming dominant and adding their genes into the Addo herds, officials relocated a number of dominant Addo males into other parks.

Animal extinction is big a threat to some animal species. According to the text “ The Impact of Animal Protection”, many nature parks have supervised breeding programs that allow numbers to increase. Many people think that animals should be able to repopulate by themselves. Keeping animals protected has proven to be beneficial and increase the populations of endangered animals. According to the text “The Impact of Animal Protection” these programs have helped bring several animals - black footed

Also as mentioned in Radiolab, the problem animals are often older males that pick more fights and kill the younger species (“The Rhino Hunter”). The species that are although endangered, removing the specie that is more problematic will benefit the other species more. By targeting only the animals that are problematic, often past reproductive age, it benefits the younger species. For example, the older species are more known for picking fights with other fellow endangered species. This often results in catastrophic, messy fights that can kill or severely injure both of them. By hunting the animal that is more dangerous to a species, will benefit the species more, because it increases their survival without the problematic animal to cause harm. The wildlife conservation’s goal is to preserve wildlife, but if an animal is causing harm to the other animals, it is better for the other animals if the problematic animal were to be hunted, because the money gained would go toward saving the

One of the most common frogs found in the richly diverse Amazon Basin is Camelus dromedarius, the camel. This large ruminating hoofed mammal, also known as Arabian camel, Dromedary Camel, One-Humped Camel, lives throughout the deserts of Saudi Arabia, Kuwait, Iraq, Yemen, and Africa (Abdelhamid, 2014). “Dromedarius” is a large, even-toed ungulate with one hump on its back (El-Bahrawy, 2015). This animal has a normal mammal life reproduction cycle, and a historical evolution. It is now a part of the culture of many Bedouin tribes and is a crucial part of customs and traditions of many Middle Eastern society. This mammal has unique characteristics such as a long-curved neck, deep-narrow chest, and a single hump (Encyclopedia of Life, n.d.).

Calves are dependent on their mother’s milk for 5 months after birth (Fay 1982). However, some calves eat some invertebrates by the time they are 6 months old. Calves can consume benthic material after their first year but will continue to consume their mother’s milk until they are two (Fay 1982). If the adult female does not have a new offspring, the calf can continue to suckle milk after two years (Fay 1982). Females are facing difficulty nourishing themselves and caring for their young. If the adults cannot adapt to free ice and carrying their young, the population will decline (Cooper et al. 2006).

A study at the Tama Zoological park was done over the course of five months observing

This research project is set out to be able to determine if ungulates have a preference on habitat. This will be based on several data collections done within Mankwe Wildlife Reserve which has multiple habitats. The aim of this project is to determine if ungulates do have a preference and if it is species specific or just for that certain individual.

They reproduce rapidly, as generally it is the case with small prey animals. No matter how well they are cared for, they possess somewhat short life span. Generally they have short gestational periods and their quick sexual maturity makes effective rodent control decisive. The reproductive cycle and the number of these rodent’s offspring increases with sufficient water, food and harbourage.
