In the past six years, the Endangered Wildlife Trust has successfully placed about 110 Anatolian Shepard dogs that are protecting goat, sheep and cattle ranches from predation by leopard, cheetah, caracal, wild dog, and jackal. Washington, D.C. (PRWEB) June 22, 2012 The Feline Conservation Federation (FCF) co-managed Rare Species Fund (RSF) just awarded $5,000 support for the Endangered Wildlife Trust (EWT), human-wildlife conflict mitigation program in South Africa. The Human-Wildlife...

Species Interactions Could Be Affected By Global Warming
2012-06-23 09:06:42

Yale and University of Connecticut researchers report that more extinctions will take place due to global warming should "scientists fail to account for interactions among species in their models." According to Phoebe Zarnetske, primary author and postdoctoral fellow at Yale´s School of forestry & Environmental Studies department, “Currently, most models predicting the effects of climate change treat species separately and focus only on climatic and environmental drivers."...

Major new marine herbivory study Coral reefs and seashores largely look the way they do because large fish and urchins eat most of the seaweed that might otherwise cover them, but a major new study has found that the greatest impact of all comes from an unexpected quarter — small marine snails. The study published in the journal Ecology Letters is the largest of its kind ever undertaken into the ecological impacts of marine grazing animals: it was led by Associate Professor...

Everything Within Balance: As Predators Decrease, Ecosystems Suffer
2012-04-10 12:37:03

As predators dwindle in the Northern Hemisphere, populations of their would-be prey begin to flourish. A new survey suggests such large populations are harmful to their specific ecosystems. Scientists from Oregon State University examined 42 studies from the past 50 years and found that as wolves disappear from the northern United States, Canada, and Alaska, populations of moose and deer swell. The resulting boom in moose and deer populations can be harmful to other living things in the...

When it comes to battling a deadly parasite epidemic, it may be better not to fight it.  A new study of freshwater zooplankton suggests less is more when it comes to evolving against a parasitic epidemic. The zooplankton, known as Daphnia dentifera, has been found to endure a yeast parasite infection known to affect more than 60% of its population. What scientists found interesting is how quickly the Daphnia population evolves, balancing infection, resistance, and reproduction....

When battling an epidemic of a deadly parasite, less resistance can sometimes be better than more, a new study suggests. A freshwater zooplankton species known as Daphnia dentifera endures periodic epidemics of a virulent yeast parasite that can infect more than 60 percent of the Daphnia population. During these epidemics, the Daphnia population evolves quickly, balancing infection resistance and reproduction. A new study led by Georgia Institute of Technology researchers reveals that...

The long-term impact of climate change on natural communities of wild animals could be better understood thanks to a new study The long-term impact of climate change on natural communities of wild animals could be better understood thanks to a new study. The research will help predict how migration of animals or changes to their habitats associated with climate change could impact on the evolution of relationships between predators and their prey. Scientists have shed light on how...

Sawfish Behavior Leads To Species Own Decline
2012-03-06 05:58:15

[ Watch the Video ] A team of researchers led by Barbara Wueringer of the University of Queensland, Australia have been studying the feeding habits of the freshwater-dwelling sawfish Pristis microdon. The researchers found that when the sawfish feeds, it uses electrosensors in its long snout to detect the location of the prey in the water. The sawfish swipes, several times per second, at its prey with a side to side motion with enough force to saw the fish in half. The sawfish would...

Squirrels and raccoons will give up food to avoid ticks Here´s a riddle: What´s the difference between a tick and a lion? The answer used to be that a tick is a parasite and the lion is a predator. But now those definitions don´t seem as secure as they once did. A tick also hunts its prey, following vapor trails of carbon dioxide, and consumes host tissues (blood is considered a tissue), so at least in terms of its interactions with other creatures, it is like a lion...

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...
