• Hippopotamus - biology.

  hippo backs up to its droppings and uses its tail as a paddle, flicking the dung through the air. This creates a pile that can become several meters wide over time. Male river hippos start to establish territories when they are in their early 20s, and they may eventually control more than 250 m (820 ft) of the water's edge.Subordinate males come and go freely, but a rival male will spark a confrontation if it tries to intrude. The territory owner and intruder face each other open-mouthedand, if...

• La Corse UNE MONTAGNE DANS LA MER

  • Sa situation géographique et son relief expliquent la double influence, marine et montagnarde, que subit la Corse. • les variations de dénivelé entre le littoral et les hauteurs de l'arrière-pays engendrent des contrastes marqués qui se traduisent tant au niveau des températures que des précipitations dans deux types climatiques principaux : climat méditerranéen à basse altitude, sec (moins de 700 mm de pluie) ; climat alpin à haute altitude, h...

• Killer Whale - biology.

  V REPRODUCTION Mating occurs more often among killer whales of different pods to avoid inbreeding within pods. About 16 to 18 months after mating, females give birth to a single calf.Newborn calves weigh about 200 kg (440 lb) and are about 2.5 m (8 ft) long. Mothers nurse their calf for 14 to 18 months, although mothers continue to be protectiveof their young long after the offspring have been weaned. Scientists do not know how long killer whales live in the wild. Scientists estimate that male...

• Antelope - biology.

  antelopes still display complex patterns of behavior, although much of it is instinctive rather than learned. In open habitats, antelopes run a high risk of predation (being preyed upon). To survive they use several kinds of defensive strategy, including living in herds. Herd living ensures that many pairs of eyes and ears are on the alert for danger. Herd living also gives individuals a better chance of avoiding attack, because predators canchoose from many potential targets. When danger thre...

• Corse.

  Après la fondation d'Alalia (future Aleria) par les Grecs de Phocée, vers 560 avant J.-C., l'île fut disputée entre les Carthaginois et les Romains. Vainqueurs en 259 avant J.-C., ceux-ci en firent un lieu de bannissement sous l'Empire (Sénèque y fut exilé). Au Moyen Âge, elle fut l'enjeu de rivalités entre la papauté, Pise et Gênes, laquelle finit par l'emporter en 1284. Les Génois tentèrent de faire de la Corse un centre agricole, mais les nombreuses révoltes des habitants, organisés en clans,...

• Giraffe - biology.

  One of the most striking elements of giraffe behavior is the duel between males fighting for mating privileges. Giraffe duels are among the most extraordinary in theanimal kingdom. They start when two males approach each other and begin to rub and intertwine their necks. This behavior—known as necking—allows the opponentsto assess each other’s size and strength. Often, necking alone is enough to establish seniority. If not, the rivals begin to exchange blows with their heads. Each giraffebraces...
