Image 1 - Returning Wolves Transform Yellowstone
2011-12-23 05:05:47

[ Watch the Video ] On the 15th anniversary of the return of wolves to Yellowstone National Park, a quiet but profound rebirth of life and ecosystem health is emerging, scientists conclude in a new report. For the first time in 70 years, the over-browsing of young aspen and willow trees has diminished as elk populations in northern Yellowstone declined and their fear of wolf predation increased. Trees and shrubs have begun recovering along some streams, providing improved habitat for...

Caterpillars Mimic One Another For Survival
2011-12-17 04:53:44

A new study in the current issue of The Annals of the Entomological Society of America helps scientists better understand how organisms depend upon one another In the world of insects, high risk of attack has led to the development of camouflage as a means for survival, especially in the larval stage. One caterpillar may look like a stick, while another disguises itself as bird droppings. Though crypsis may have its advantages, University of Florida researchers uncovered some of the most...

People and giant snakes not only target each other for food — they also compete for the same prey, according to a study co-authored by a Cornell University researcher. More than a quarter of the men in a modern Filipino hunter-gatherer group have been attacked by giant pythons – yet those same hunter-gatherers often target the pythons as their next meal. The study also finds that both the hunters and the pythons routinely eat local deer, wild pigs and monkeys. "Hunter-gatherers...

The Physics Behind Great White Shark Attacks On Seals

Scientists use basic principles of underwater optics, physics to understand predator-prey interactions A new study examining the complex and dynamic interactions between white sharks and Cape fur seals in False Bay, South Africa, offers new insights on the physical conditions and biological factors underlying predator-prey interactions in the marine environment. University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science assistant professor Dr. Neil Hammerschlag, and a...

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...

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...

Great Kiskadee, Pitangus sulphuratus

The Great Kiskadee (Pitangus sulphuratus) is a species of passerine tyrant flycatcher found from southern Texas and Mexico south to Uruguay and central Argentina. They are also found on Trinidad. They have been introduced to Bermuda in 1957, and Tobago in 1970. The adult Great Kiskadee is 8.7 inches long and weighs 2.2 ounces. It has a black head with a white eye stripe and concealed yellow crown stripe. The upperparts are brown. The wings and tail are brown and have reddish-brown fringes....

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...
