Latest Predation Stories
Research by the University of Exeter has revealed that ants have a big impact on their local environment as a result of their activity as 'ecosystem engineers' and predators.
Large predators are much more vulnerable than smaller species to environmental changes, such as over-hunting and habitat change, because they have to work so hard to find their next meal, according to a new study.
There may be many similarities between the importance of large predators in marine and terrestrial environments.
The food chain - the number of organisms that feed on each other â€” in the world's streams and rivers depends more upon the size of the stream and whether the waterways flood or run dry than the amount of available food resources, Yale University and Arizona State University (ASU) researchers report online in the Oct. 14 issue of the journal Science Express.

The evolutionary history of the Thaumoctopus mimicus lineage reveals the steps it took to become a master of disguise.

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...
