Chimpanzee populations once spanned equatorial Africa from the western coast to Tanzania. Today there between 80,000 and 130,000 chimpanzees in the world. The human species is responsible for this decline. Logging companies and agriculture are wiping out large areas of the rain forest and destroying the chimpanzees' habitat. (In Sierra Leone, 97 percent of the rain forest habitat has been destroyed.

Washoe was probably born in September of 1965, celebrates her birthday on June 21st - the "Project Washoe" anniversary. See similar questions...

No. In free-living chimpanzees Jane Goodall has observed incest taboos. Mothers do not allow their sons to copulate with them, sisters do not copulate with their brothers and females do not copulate with older males in their familial group. Though none of these chimpanzees are biologically related, they have grown up in this family group and show no sexual behavior toward one another. If they did show sexual interest, we would have Dar and Loulis vasectomized. See similar questions...

No. Although the wolf survives as an endangered species in a handful of states, from 7,500 to 10,000 wolves populate Alaska — from the most remote wilderness region to the suburbs of our largest cities. Because so much of this state is undeveloped, with more than 160 million acres permanently set aside in protected status (an area larger than California), the wolf is assured of a permanent home in Alaska.

There are many different reasons that animals are endangered, especially loss of their habitat -- where they live, eat, and raise their young. Protecting endangered and threatened species and restoring them to a secure status in the wild is the primary objective of the endangered species program of the U.S. Fish and Wildlife Service, an agency of the Department of the Interior. The Endangered Species Web site can be accessed at <http://www.fws.gov/r9endspp/endspp.html>. See similar questions...

NO! And they never were. In fact, Atlantic Swordfish, previously reported threatened, and after just a few years in quota management, is thriving, replenishing its species stocks to a sustainable level. Meaning- As long as Fisherman are kept to the current limit of harvest, that the species reproduces quickly enough so that their numbers will not deplete, but rather will grow.

No, but one species, C. pelias, is rare within its range. A rigorous ecological study would be required to determine if it's in trouble. See similar questions...

In the 1990's, there were isolated instances of UFO being broadcast around the world -- it has shown up on BBC2 in the UK, the Sci-Fi Channel in America, and also on channels in Australia, Japan, Germany, Italy, and New Zealand. However, there haven't been reports of UFO being broadcast in the past few years, so the DVDs appear to be the only option for seeing the series these days. Besides, with the DVDs the episodes are uncut, and the picture quality can't be beat. See similar questions...

According to one count, 6,703 separate languages were spoken in the world in 1996. Of these, 1000 were spoken in the Americas, 2011 in Africa, 225 in Europe, 2165 in Asia, and 1320 in the Pacific, including Australia. These numbers should be taken with a grain of salt, because our information about many languages is scant or outdated, and it is hard to draw the line between languages and dialects. But most linguists agree that there are well over 5,000 languages in the world. See similar questions...

Although the endangered languages are spoken by minority communities, these communities account for most of the world's languages. See similar questions...

Across their range in Australia they are found in Queensland, New South Wales, Victoria and South Australia and are NOT considered endangered but are listed as vulnerable. However, some local isolated populations of koala could be considered endangered due to habitat loss through housing development. Their food trees are threatened and therefore they could face local extinction. See similar questions...

Loss of natural roost sites such as trees which, are removed for development, and change of land use, and suitable trees (old ones with holes in) being cut down, for public safety reasons. Caves roosts are often visited by vandals and are used in recreational activities with little or no regard for bats living there. Buildings that bats use are refurbished and modified, sometimes destroying the roost and it's entry. Ignorance is one of the main factors. See similar questions...

Under double-blind conditions, we have found that the chimpanzees communicate information in American Sign Language (ASL) to human observers. They use signs to refer to natural language categories: e.g. DOG for any dog, FLOWER for any flower, SHOE for any shoe, etc. The chimpanzees acquire and spontaneously use their signs to communicate with humans and each other about the normal course of surrounding events.

Each chimpanzee reacts differently to visitors and the reaction of each chimpanzee changes from day to day. At times, they appear interested in the visitors and may come to the window to sign and interact. At other times, they may be resting or interacting with each other. Much like humans, they are not always ready for guests. We have found that limiting the length of observation time helps reduce the chimpanzees' stress level. See similar questions...

Free-living chimpanzees typically live and move in home ranges that vary in size from 10- to 24-square kilometers, and may travel as much as one- to five-square kilometers a day. They build their nests and climb up to 80 feet above the ground and also spend time traveling and climbing in the overhead canopy. Because of this, it is important that the chimpanzee areas in the building are complex, have vertical space, and allow for some freedom of movement. See similar questions...

Washoe was raised as if she were a deaf child by Beatrix and Allen Gardner at the University of Nevada in Reno from 1966 to 1970. Roger Fouts joined the project as a graduate student in 1967. Washoe, acquired at the age of 10 months, was immediately immersed in American Sign Language with a socially enriched environment where she soon learned to use ASL in daily interactions with her human companions. Moja, Dar and Tatu were immersed in ASL in a similar fashion. See similar questions...
