Latest Predation Stories
Populations of predators and their prey usually follow predictable cycles.
New Method Described in "The Journal of Chemical Physics" Simplifies Studies of Predator-Prey Interactions and other "Bistable" Systems WASHINGTON, May 6, 2014 /PRNewswire-USNewswire/
If an insect drew a line as it chased its next meal, the resulting pattern would be a tangled mess.
252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water.
A study of grasslands on six continents suggests a way to counteract the human-made overdose of fertilizer that threatens to permanently reduce their biodiversity: let grazing animals crop fast
Long-prized for their thick fur, the cuddly Eurasian beaver has been hunted by humans for thousands of years and a new genetic study from a large group of international researchers has found that predation by humans has significantly cut down the genetic diversity of these animals.
Skunks do it best when halting a predator in its tracks, unleashing a noxious stream of urine that can send the most lethal of hunters in the opposite direction. Other animals of the same group tend to rely on strong social bonds to thwart impending attacks.
When people see a skunk, the reaction usually is “Eww,” but when they see a group of meerkats peering around, they often think “Aww.”
To understand how feeding interactions are structured, researchers from Finland and Canada chose to focus on one of the simplest food webs on Earth: the moths and butterflies of Northeast Greenland, as attacked by their specialist enemies, parasitic wasps and flies developing on their prey (called host), killing it in the process.
Through the analysis of striking aerial video footage, a pair of researchers from Haverford College in Pennsylvania has found that falcons hunt their prey by heading them off during mid-air pursuit, according to a new report in The Journal of Experimental Biology.
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 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...
