Bacteria May Allow Animals To Send Quick, Extensive Messages

Michigan State University Twitter clips human thoughts to a mere 140 characters. Animals' scent posts may be equally as short, relatively speaking, yet they convey an encyclopedia of information about the animals that left them. In the current issue of the Proceedings of the National Academy of Sciences, a Michigan State University researcher shows that the detailed scent posts of hyenas are, in part, products of symbiotic bacteria, microbes that have a mutually beneficial relationship...

Study Finds People, Livestock And Carnivores Share Same Space

Michigan State University In the southern Rift Valley of Kenya, the Maasai people, their livestock and a range of carnivores, including striped hyenas, spotted hyenas, lions and bat-eared foxes, are coexisting fairly happily according to a team of coupled human and natural systems researchers. “I wouldn´t call the results surprising,” said Meredith Evans Wagner, a visiting scholar from the University of Florida in the Center for Systems Integration and Sustainability...

Captive Animals Better Problem Solvers Than Their Wild Counterparts

Watch the video "Studying Hyena Problem Solving Skills" April Flowers for redOrbit.com - Your Universe Online Historically, tests on an animal´s ability to problem solve have been conducted on captive animals. Recently, however, a shift has been made among researchers who are now trying to run those tests on animals in their native habitats. A new study from scientists at Michigan State University and the University of California, Berkeley has found vast differences between the...

Brett Smith for redOrbit.com — Your Universe Online Researchers from Michigan State University working in Kenya have shown for first time that groups of hyenas possess different odor-producing bacterial communities within their scent glands that they use to communicate everything from age to social status. “A critical component of every animal´s behavioral repertoire is an effective communication system,” said Kevin Theis, an MSU molecular biologist. “It is...

Hyenas Solve Problems Faster When They Think Outside The Box

redOrbit Staff & Wire Reports - Your Universe Online Trying many different solutions is required for solving innovative problems. That´s true for humans and now researchers from Michigan State University show that it is also true for hyenas Steel puzzle boxes with raw meat inside were presented to wild spotted hyenas in Kenya. The hyenas had to slide open a bolt latch to get the meat. Only nine out of 62 hyenas succeeded even though most of the animals had many opportunities to...

Many Christians give up certain foods for Lent, however ecologists have discovered these changes in human diet have a dramatic impact on the diet of wild animals. In Ethiopia, members of the Orthodox Tewahedo Church stop eating meat and dairy products during a 55-day fast before Easter. As a result, spotted hyenas too change their eating habits — from scavenging waste from butchers and households to hunting — new research in the British Ecological Society's Journal of Animal...

As large, carnivorous mammals, spotted hyenas are well known for their competitive nature; however, recent work suggests that their clan structure has similarities to some primate social systems such as those of the baboon and macaque. San Diego Zoo Global researchers have documented relatedness between individuals and how this factor appears to influence their social behaviors. "Understanding how animal social systems work is an important part of learning what we need to know to conserve...

When it comes to producing more offspring, larger female hyenas outdo their smaller counterparts. A new study by Michigan State University researchers, which appears in Proceedings of the Royal Society, revealed this as well as defined a new way to measure spotted hyenas' size. "This is the first study of its kind that provides an estimate of lifetime selection on a large carnivore," said MSU graduate student Eli Swanson, who published the paper with MSU faculty members Ian Dworkin and Kay...

A team from the National Museum of Natural Sciences (CSIC) has analyzed the impact of climate change on spotted hyena survival in Europe over 10,000 years ago. These changes played an important role, but the scientists say studies are still needed to look at the influence of human expansion and changes in herbivorous fauna on the definitive extinction of this species across the continent. "Climate change in the past was not directly responsible for the extinction of the spotted hyena in...

Acoustic analysis of the 'giggle' sound made by spotted hyenas has revealed that the animals' laughter encodes information about age, dominance and identity. Researchers writing in the open access journal BMC Ecology recorded the calls of 26 hyenas in captivity and found that variations in the giggles' pitch and timbre may help hyenas to establish social hierarchies.

The aardwolf (Proteles cristatus) is a small insectivorous hyena, native to Eastern and Southern Africa. The name means "earth wolf" in Afrikaans. Unlike other hyenas, the aardwolf is a defenseless animal whose diet almost completely consists of termites. The natural enemies are deterred by the superficial resemblance to the more aggressive hyena species. The aardwolf is the only surviving species of the subfamily Protelinae. Physical characteristics The aardwolf looks most like the...

The striped hyena (Hyaena hyaena) is closely related to the brown hyena. It lives in northern Africa, the Middle East, Pakistan and western India. It is extinct in Europe, but can occasionally be spotted in Anatolia, Turkey. Striped hyenas are largely scavengers, but will also eat small animals, fruit and insects. They are nomadic, moving from water hole to water hole, but never straying more than 6 miles from one. Striped hyenas hunt in solitude but do congregate in small family groups. Like...

The brown hyena (Parahyaena brunnea, formerly Hyaena brunnea) lives mainly in the Kalahari and Namib deserts of southern Africa. It is smaller than the spotted hyena, and unlike its spotted cousin, is largely a scavenger. It is the largest land animal to derive most of its diet from scavenging. Because of the scarcity of food in the desert, the brown hyena supplements its diet with fruit and vegetables. Along the Namib coastline they are known to snatch seal pups. Also unlike the spotted...

The spotted hyena, or laughing hyena, (Crocuta crocuta) is the largest and best-known member of the hyena family. The spotted hyena ranges in size from 3.1 to 5 ft (95 to 150 cm) long along the head-and-body and stands from 2.5 to 3 ft (75 to 90 cm) at the shoulder. The normal weight range for the male is 100 to 132 lb (45 to 60 kg). The females normally weigh from 121 to 165 lb (55 to 75 kg). Some exceptionally large females have been in the ballpark of 200 lb (90 kg). Behavior The...
