The maned wolf – once a thriving species throughout South America – now lives in only four countries and is listed as near threatened on the IUCN Red List of Threatened Species. Because the maned wolf population is declining rapidly and growing more fragmented due to its habitat being converted into farmland, establishing a sustainable captive population is critical to the species’ long-term survival. Artificial insemination (AI) is a valuable tool for enhancing many wildlife species in zoos, but AI protocols haven’t been established yet in maned wolves. Fundamental data associated with sperm freezing and hormone therapies are needed. This study will examine factors affecting sperm cryo-survival and develop an optimal hormone therapy for controlling reproductive cycles in females in hopes of increasing the knowledge of maned wolf reproduction and allowing AI with fresh or thawed sperm. The results will help enhance the management of this species.

There are many reasons why wolves are endangered, Most people used to be afraid of wolves and thought they were dangerous to humans. For a long time, people would get money for bringing in a dead wolf. This was called bounty hunting //(between 1850 and 1900 more that a million wolves were killed. In 1907 the call was given for the total extinction of the species.)// People also use to poison wolves, poisoning is probably the main reason there are so few wolves left today.



There are two types of wolves in the United States, the grey wolf and the red wolf. The grey wolf is also called the timber wolf and is the largest of the 41 species of the dog family, Canidae. The size of wolves vary with their location. Adults may grow to a length of 164 cm (6.5 ft.) from nose to tip of tail and be about 90 cm (36 in.) high at the shoulders. They may weigh as much as 80 kg (175 lbs.) in weight. The larger sizes are commonly seen in the male wolves. The wolf is a powerful, muscularly built animal with a thick bushy tail. The color of wolves vary from pure white, the most common color in the far north of North America, through mottled gray to brown or black. Grizzled gray is the most common color.
