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...

Wolves Could Help Recovery Of Canada Lynx
2011-08-31 05:39:58

  As wolf populations grow in parts of the West, most of the focus has been on their value in aiding broader ecosystem recovery — but a new study from Oregon State University also points out that they could play an important role in helping to save other threatened species. In research published August 30 in Wildlife Society Bulletin, scientists suggest that a key factor in the Canada lynx being listed as threatened under the Endangered Species Act is the major decline of...

Study shows that selection pressures imposed by predator fungi have shaped escape behavior in microscopic worms Escape responses are some of the most studied behaviors by neurobiologists who want to understand how the brain processes sensory information. The ability to evade predators plays a vital role in the process of natural selection. Animals explore their environment to find food, find mates and locate new habitats, and have developed distinct escape responses to avoid predators,...

What do a herd of gazelles and a fluffy mass of clouds have in common? A mathematical formula that describes the population dynamics of such prey animals as gazelles and their predators has been used to model the relationship between cloud systems, rain and tiny floating particles called aerosols. This model may help climate scientists understand, among other things, how human-produced aerosols affect rainfall patterns. The research recently appeared in the Proceedings of the National Academy...

Impacts include increases in infectious diseases and invasive species, as well as changes in soil, water, vegetation, and the atmosphere STONY BROOK, N.Y., July 15, 2011 /PRNewswire-USNewswire/ -- "Trophic Downgrading of Planet Earth," a review paper that will be published on July 15, 2011, in the journal Science, concludes that the decline of large predators and herbivores in all regions of the world is causing substantial changes to Earth's terrestrial, freshwater, and marine...

The worldwide decline of top predators, or "consumers", such as wolves, sharks and lions, is threatening to drive other species to extinction, an international team of 24 scientists reported on Thursday. The research shows for the first time the critical importance that large animals have within the world's ecosystem. "Until recently, large apex consumers were ubiquitous across the globe and had been for millions of years. The loss of these animals may be humankind's most pervasive influence...

Biologists worldwide subscribe to the healthy herds hypothesis, the idea that predators can keep packs of prey healthy by removing the weak and the sick. This reduces the chance disease will wipe out the whole herd, but could it be that predators can also make prey populations more susceptible to other predators or even parasites? Biologists at the Georgia Institute of Technology have discovered at least one animal whose defenses against a predator make it a good target for one opportunistic...

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...
