ALBUQUERQUE, N.M., May 24, 2011 /PRNewswire/ -- Ranchers manage the forces of mother nature every day, but recent extreme drought conditions are posing new challenges to anyone working with land management on ranches in the "Dust Bowl" states of the Midwest and Southwest. According to the U.S. Drought Monitor, parts of Texas covered by extreme drought have tripled to 40 percent in recent months. Officials say it's a similar situation in Oklahoma where the four months following Thanksgiving...

New findings of researchers from Tel-Aviv University show that predator-prey interactions between ground beetles of the genus Epomis and amphibians are much more complex than expected. The study was published in the open access journal Zoo Keys. "Amphibians are typical insect predators and their diet may include adult beetles, ground beetles in particular. The recently filmed successful attacks of the beetles on toads and frogs brought new insights on the amphibian-insect interactions, and...

Team from MBL, West Point uses new imaging technology to 'see' camouflaged marine animals in the eyes of their predators How could a colorblind animal know how to change its skin color to blend into its surroundings? And what will the animal's predator "see," looking at its prey before and after it hides? These provocative questions are addressed in article published today by a collaborative team from the Marine Biological Laboratory (MBL) in Woods Hole, Mass., and the U.S. Military Academy...

An ecosystem is like a great organism in that the species in it behave in a manner similar to the manner in which cells behave within the human body: the group forms a permanent entity, although the entities that form it are constantly being substituted. This is the conclusion that can be drawn from a theoretical study carried out by researchers at the Universidad Carlos III de Madrid (UC3M "“ Carlos III University of Madrid). These scientists have developed a mathematical model that...

A new University of Florida study shows cats are the dominant predator to mockingbird eggs and nestlings in urban areas, prompting conservationists to urge pet owners to keep felines indoors at night. The findings challenge assumptions that urban areas are places of refuge for nesting mockingbirds, a species researchers say plays an important role in controlling insect pests and serving as environmental indicators for metropolitan areas. "I thought the cats probably really hammered them...

Rotational grazing in native pasturelands benefits wildlife Rotational grazing of cattle in native pasturelands in Brazil's Pantanal and Cerrado regions can benefit both cattle and wildlife, according to a new study by the Wildlife Conservation Society. The technique, which has been adapted for a variety of livestock worldwide, calls for cattle to graze in small areas for shorter periods of time before moving onto other pastures. The result is a greater forage base that produces larger, more...

Extinction of fishes 360 million years ago created natural ecology experiment In modern ecology, the removal or addition of a predator to an ecosystem can produce dramatic changes in the population of prey species. For the first time, scientists have observed the same dynamics in the fossil record, thanks to a mass extinction that decimated ocean life 360 million years ago. What was bad for fish was good for the fish's food, according to a paper published May 2 in Proceedings of the National...

Precipitation and predators key in ecological regulation of infectious disease A little information can go a long way when it comes to understanding rodent-borne infectious disease, as shown by a new study led by scientist John Orrock of the University of Wisconsin-Madison and colleagues. The researchers studied wild deer mouse populations on the Channel Islands off the southern coast of California.  The mice carry a variant of hantavirus--a disease spread by rodents--called Sin Nombre...

Fiddler crabs would all end up as dinner for seagulls were it not for their sophisticated threat detection system, vision scientists have found. Researchers in The Vision Centre have announced an important advance in understanding how simple animals distinguish between threats and non-threats by looking for a combination of visual cues. "These crabs can't distinguish shapes and must constantly compete with birds that are bigger and have sharper sight," says Dr Jan Hemmi from the ARC Centre of...

For those old enough to remember Mutual of Omaha's "Wild Kingdom" television series, the dynamics of predator-prey relationships seemed clear enough: predators thinned out prey populations, which enabled a smaller, but stronger, population to survive and reproduce. However, a new paper by University of Notre Dame biologist Gary Belovsky appearing in the prestigious journal Ecology Letters suggests that predator-prey relationships are much more complex than originally thought. The paper arose...

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) 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...
