The Reproductive Cycles Of Human Animals

A few weeks ago, I spent a lovely Monday afternoon observing two different primates at the Santa Ana Zoo. I got to the zoo around two in the afternoon, and to my surprise, the zoo was decently crowded. The Santa Ana Zoo is smaller in comparison to other zoos like the Los Angeles Zoo, but still had a decent amount of animals there. Covering a small 20 acres of land, I came across two primates that fit perfectly for the purposes of this course project. I chose to observe an endangered ape, the white-handed gibbon, and an endangered new world monkey, the golden-headed lion tamarin.

As the animal rights movement has developed and grown substantially in recent years, there has been an increased focused on the welfare of captive animals. A popular institution that has received much attention for keeping animals captive is the zoo. Because of this focus, zoos have responded by publicizing their positive benefits for existence in order to justify keeping these animals on display. Since the term “zoo” can have a wide variety of meaning and characteristics, it is important to define what constitutes a zoo in this essay. Zoos are defined as a facility in which animals are confined within enclosures, displayed to the public, and

Recently, DNA testing has been employed to create a genetic database of endangered animal species. Using this information, scientists have even cloned animals.

In “The Stripes Will Survive” it states “ In 1981, the American Zoo and Aquarium association (AZA) started the Species Survival Plan (SSP) to make sure that threatened and endangered species don't disappear. The members of the Tiger SSP teach the public about the plight of tigers and do research. They keep a computerized family tree of zoo tigers that helps match males and females for breeding.” This shows that the AZA is taking big steps to make sure that tigers survive and breed.

The sexual response cycle is a term referencing the changes that occur within the body as it is becoming aroused (Nevid & Rathus, 2010). This cycle, the sexual response cycle, consists of four phases. Phase one is excitement. Phase two is plateau. Phase three is orgasm. Phase four is resolution. Even though the changes that occur in men’s and women’s bodies differ in each phase, they do have some things in common. So that we may learn and better understand what makes us different and the same, we must first learn the components that make up the sexual response cycle. There are two components and they are vasocongestion and myotonia (Nevid & Rathus,

A key element in the life of any individual is to be able to reproduce. Nonhuman primates number only 250 species but display great diversity in grouping patterns. We call some of these types of groupings a one male polygyny or monogamy. However, the main focus today is that these primates have evolved different strategies, behavioral and ecological, to cop with the need to balance limited food supplies while avoiding predators with intensions of mating and or harming their offspring. It has been assumed that in order for male primates to reach mating success, they must have to take on the task of always being present to the female and her offspring’s. I believe that I will argue that monogamy and one male polygyny are different yet both

On Friday, March 31, a observation study was conducted at the L.A. Zoo. The time of arrival for the observation was at 11:48 am and the end of the observation was at 2:42 pm. The weather condition at the zoo was very sunny with a mild gust of wind every so often, which is a perfect weather condition to conduct a study. The main reason for conducting this observation study was to study and gather information about the many different types of primate that are located at the zoo. To see how different or similar each primate is to one anotherin different aspects.

For this discussion, I chose to examine the reproductive nature of mountain lions and hammer head sharks. Mountain lions are solitary cats that live in various mountainous regions of north and south America, but a male and female come together socially in order to mate during the 3-10 day estrus period. Due to their solitary nature, mountain lions rely on scent marking in different territory as well as a mating call of the female in order to initiate the potential for sex. Typically, when a male and female find each other; they spend several days together during the mating period and he may hunt for her and run mating circles around her. Mountain lions are polygynous and both the males and females will mate with multiple individuals throughout

Dr. Kim Vonnahme has been a very important addition to the Animal Science Department at NDSU for the past eleven years. She has brought her tremendous knowledge of the reproductive tracts in animals to research and hands on projects for the students here at NDSU. Dr. Vonnahme received her Bachelor of Science Degree in Animal Science at Iowa State University in 2006. She continued to further her educational background by attending Oklahoma State University to obtain her Master’s Degree in Animal Science in 1998. Afterwards, she attended University of Wyoming to receive her PhD in Reproductive Physiology (Kim Vonnahme, 2014; Research Profile-Kim, 2014).

In recent years, animals in captive environments such as zoos and theme parks have grown more controversial. The literature I have reviewed focuses on a particular group of animals in captivity, cetaceans. Cetaceans include whales, dolphins, and porpoises. The literature includes a range of themes, from their unique level of intelligence to why they may mentally and physically suffer in captive environments. However, it all connects to how and why these animals live and behave differently in captive environments than their wild counterparts.

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.

Antelopes are terrestrial mammals that travel in herds and are known to display aggregative calving behavior. Human disturbance is one of the leading causes of deselecting a calving site. These herbivores are indigenous to Africa and Eurasian. They are capable of living a variety of habitats; a great percentage of them inhabit the African savannahs. They have the ability to swim across rivers and cover extensive distances; which are critical adaptations that make their annular migrations successful. Most antelopes are sexually dimorphic and the herd usually exhibits a female-biased sex ratio. The females display early reproductive maturity (around 8 months) and have a long reproductive life (up to a decade). Antelopes are classified as critically endangered by the International Union for Conservation of Nature (IUCN).

Do you know how you were born? Do you know how you came to be? The reproductive system is the system that made that all possible. Without the reproductive system you wouldn’t have been born. In order to produce offspring, the male and female reproductive systems have to be different. Each system has different parts, problems and care. Each system have different purposes, the male reproductive system’s function is to produce sperm, while the female reproductive system’s function is to produce ova, store ova and house a fertilized egg.

The study and research of reproduction in elephants is increasingly critical in consideration of the quickly dwindling population numbers and estimates. The current Asian elephant population is estimated to lie between 50,000-70,000 across the world, with 15,000 of these individuals in captivity. African elephant population numbers are low as well after serious culling through hunting and poaching. These numbers make the low reproduction rates a great concern as elephants do not currently sufficiently reproduce at an adequate rate to sustain population size.12

Reproduction is an important function for the survival of all living things. Some species reproduce asexually and other species reproduce sexually. Human reproduction, however, involves sexual intercourse between a man and a woman. For many years humans were only able to procreate through sexual intercourse; although with the recent advancements in medicine and technology, humans are now able to conceive a child in other ways. Those who cannot or who do not want to conceive through sexual intercourse have options to conceive a child through IVF (In vitro fertilization) or AI/ IUI (artificial/intrauterine insemination). IVF is a procedure in which a female’s eggs are extracted and fertilized with sperm in a lab. When the fertilized eggs have developed into embryos, it is implanted in the uterus. AI/IUI is a procedure in which sperm from a donor or partner is directly inserted into the uterus through a catheter. These alternatives to become pregnant were considered “unnatural” and “outlandish”, because of the engagement of the newly assisted technology and the lack of human intimacy. Today the methods are widely accepted by most of society and are commonly used. Yet, questions were raised when Dolly the Sheep became the first mammal to be cloned. It begged the question whether if it was possible to clone humans, and if be morally right to have human cloning as another means of reproduction. We will explore the complexity of human cloning in the case of a 34-year-old
