Oldest Super Predator Had Highly-acute Vision
2011-12-08 06:25:03

Paleontologists working on fossils from Kangaroo Island in South Australia have discovered that the Earth's first apex predator had highly acute vision that rivaled or exceeded that of most living insects and crustaceans. The researchers from South Australian Museum and University of Adelaide discovered exceptionally preserved fossil eyes of the top predator in the Cambrian ocean from over 500 million years ago: the fearsome Anomalocaris. The species is considered to be at the top of...

Shedding Light on How, Why Climate Change Effects Animals
2011-12-02 06:31:10

An international team of scientists say that they have discovered a way to predict how environmental changes will affect gray wolves living in Yellowstone National Park. The study, which is part of the Yellowstone Wolf Project, was published in the December 2 issue of the journal Science. The work was led by researchers at Imperial College London and also involved experts from the U.S. Department of the Interior, Utah State University and the University of California, according to a press...

A New Model For Understanding Biodiversity
2011-11-22 04:13:06

Researchers develop a unified theory of ecosystem change by combining spatial modeling and food web analysis Animals like foxes and raccoons are highly adaptable. They move around and eat everything from insects to eggs. They and other “generalist feeders” like them may also be crucial to sustaining biological diversity, according to a new study published this week in the Proceedings of the National Academy of Sciences (PNAS). McGill biology researchers have developed a...

Properly functioning ecosystems have their own pest management system — predation — but as new manmade ecosystems develop, these natural maintenance systems are often disrupted. In some cases, though, installing a simple nest box may be all that's needed to restore the balance, and improve avian conservation, according to a new report published Nov. 9 in the online journal PLoS ONE. The researchers, led by Julie Jedlicka of the University of California, Berkeley, monitored the...

When both a predator and its prey are conservationally at risk, it can be difficult to find the right balance of ecosystem management to sustain and protect both. Such is the case for a particular population of orcas called southern resident killer whales and their prey, Chinook salmon, off the coast of Washington State and British Columbia, but a new detailed model of the two species may provide some guidance about what must be done to conserve both. The study, reported in the Nov. 9...

Anthropologist Narrows Down History Of Animal And Human Relationship
2011-10-03 12:09:13

Anthropologist Pat Shipman says that when our prehistoric ancestors began interacting with animals they developed empathy for them. The leading American anthropologist says these ancient humans' relationships with animals helped propel humanity towards global domination. The Observer reported that Shipman said interacting with animals on an intimate basis led humans to help develop sophisticated tools and evolve enhanced communication skills. She traced humanity's animals connection...

Limits For Mountain Trail Use Identified
2011-09-23 04:20:00

  Research identifies thresholds of human activity on national park trails that lead to wildlife disturbance and ecological change A new study on human impact to wildlife in some of Canada's most popular national parks has identified limits at which trails can be used before ecological disturbance takes place. The study led by University of Calgary Masters graduate, J. Kimo Rogala, is published in the current online issue of the journal Ecology and Society. Rogala was a student of...

Image 1 - Zebras vs. Cattle: Not So Black-and-white
2011-09-23 03:57:09

  Grazing by wild animals like zebra doesn't always harm, and may help, livestock like cattle African ranchers often prefer to keep wild grazers like zebras off the grass that fattens their cattle. But a new study by Kenyan and University of California at Davis researchers shows that grazing by wild animals doesn't always harm, and may sometimes benefit, cattle. The results are published in this week's issue of the journal Science. "Although savanna rangelands worldwide...

Image 1 - Salmon, Other Fish Predators Rely On 'No Guts, No Glory' Survival Tactic
2011-09-18 05:36:09

  The phrase "no guts, no glory" doesn't just apply to athletes who are striving to excel. Salmon and other fish predators take the adage literally, by having up to three times the "gut" capacity they need on a daily basis just so they can "glory" when prey is abundant, University of Washington researchers have discovered. It's a previously unrecognized survival tactic that might apply to other top predators, such as wolves, lions and bears, according to Jonathan Armstrong, a UW...

Thomson’s Gazelle, Eudorcas thomsonii
2012-06-17 19:56:59

Thomson’s gazelle (Eudorcas thomsonii) is also known as a “tommie” and is one of the most well-known gazelle species. Named after Joseph Thomson, Thomson’s gazelle is native to Africa where it is the most commonly found gazelle. It is sometimes considered a subspecies of the red-fronted gazelle, and was previously in the genus Gazella, in the subgenus Eudorcas. Eudorcas eventually became a distinct genus, classifying some species of gazelle within their own genus. Thomson’s...

Grant’s Gazelle, Nanger granti
2012-06-15 12:08:26

Grant’s gazelle (Nanger granti) is native to Africa. Its northern range of Tanzania extends south to Ethiopia and the Sudan, and from the coast of Kenya to Lake Victoria. It prefers habitats within shrub lands and grass plains, but can also be found in regions that are more arid. In Swahili, Grant’s gazelle is called Swala Granti. It was placed within the Nanger subgenus of the genus Gazella, before Nanger became a separate genus. Grant’s gazelle holds five recognized subspecies. The...

The West Caucasian Tur (Capra caucasica), is a goat antelope found only in the western half of the Caucasus Mountain Range. They thrive in rough mountainous terrain between 2625 and 13120 feet in elevation. West Caucasian Turs are nocturnal, eating in the open at night and sheltering during the day. Females live in herds of around ten individuals, while males are solitary. The Tur stands up to 39.4 inches at the shoulder and weighs about 143 pounds. West Caucasian Turs have large but...

The Wild Goat (Capra aegagrus), is a common species of goat, with a distribution ranging from Europe and Asia Minor to central Asia and the Middle East. In the wild, these goats live in flocks of up to 500 individuals. Male wild goats are solitary and go through a period called a rut, where they are ready to mate. During the rut old males drive younger males from the maternal herds. The gestation period averages 170 days. Females usually give birth to one kid. Kids can follow the mother...
