  • Deserts are defined by how much rain they get. Most deserts, like the Sonoran in North America and Sahara in Africa, are hot. They receive less than 25cm of rain each year. The South and North Poles are also deserts but very cold.

  • Introduction. The boreal forest (also known as the taiga, a russian word meaning swampy moist forest) is found in a nearly continuous belt across North America and Eurasia. Most of Canada and Russia are covered by coniferous trees that make up this biome. This biome is defined mainly by the trees that compose it. The climax trees are furs, spruces and pines. Subclimax plant communities may have deciduous trees like larch, tamarack and birch. Much of the zone that this biome covers was formerly glaciated. Today large sections have permenent permafrost.

  • The Champions of the Animal KingdomPeople are good at a lot of things, but if animals could enter the Olympics as one team they would probably win almost all the medals! Animals can outrun, outswim, and outjump all humans. Young cheetahs learn to hunt by watching their mother. Later, they start taking part in the hunt. Cheetahs are the fastest land animal and can reach speeds of 113kph in short bursts. ©G.Ellis/GLOBIO.org Fastest Mammal on Land Cheetahs can run up to 113 kph. Fastest Mammal in Water Dall porpoises can swim up to 56 kph. Fastest Flying Bird Peregrine falcons can dive toward the ground at more than 320 kph. Fastest Flightless Bird North African ostriches are the fastest birds on land. They can run at speeds up to 72 kph. They are also the biggest bird. They can weigh 155 kg. Fastest Fish Sailfish can swim up to 109 kph. Loudest Animal The blue whale’s low-frequency pulses are as loud as 188 decibels. This is louder than a jet engine. A blue whale’s call can be detected more than 805 km away. On land, the loudest animals are howler monkeys. Their howls can be heard 4.8 km away.

  • Arctic terns migrate to and from the Antarctic - about 35,405 km round trip - each year. Among mammals, gray whales and northern elephant seals are the migration champions. They travel up to 20,900 km round trip each year. Deadliest Animal Female Anopheles mosquitoes, which carry and transmit malaria, play a role in the deaths of more than a million people each year. Most Venomous Animal A single sea wasp (a kind of jellyfish with 60 tentacles, each 4 m long) has enough venom to kill 60 adult humans. Strongest Animal The rhinoceros beetle can lift 850 times its own weight

  • Longest Gestation Asian elephants are born after a gestation period of 19 to 22 months. Largest Mammal Blue whales are the largest mammals of all time and the largest living animal. Females grow to a length of about 27 m. They may weigh well over 100 metric tons. The heaviest blue whale weighed more than 190 metric tons. The longest ever measured was more than 33 m. African elephant bulls are the heaviest land animal. Large males may weigh as much as 5,895kg. Despite their power and size, elephants are vegetarians, or herbivores. ©G.Ellis/GLOBIO.org Largest Living Animal on Land African elephants are the heaviest land animal. They are also the second tallest land animal. Large bulls (males) weigh more than 5,895 kg and are 3.5 m tall at the shoulder. Giraffes, which can grow to a height of 5 m, are the tallest land animals. Large males weigh more than 1,800 kg. Smallest Vertebrate Australia's stout infantfish, slightly smaller than the better-known dwarf goby, is less than 1 cm long. Smallest Bird Adult bee hummingbirds, found in Cuba, weigh about 2 g. Smallest Mammal Adult bumblebee bats, which live in Thailand, weigh about 2 g. Longest Lifespan In the 1770s, British explorer Captain James Cook presented a Madagascar radiated tortoise to the royal family of Tonga. The tortoise lived until 1965.

  • Slash and burn consists of cutting and burning of forests or woodlands to create fields for agriculture or pasture for livestock, or for a variety of other purposes. It is sometimes part of shifting cultivation agriculture, and of transhumance livestock herding. Historically, the practice of slash and burn has been widely practiced throughout most of the world, in grasslands as well as woodlands, and known by many names. In temperate regions, such as Europe and North America, the practice has been mostly abandoned over the past few centuries. Today the term is mainly associated with tropical rain forests. Slash and burn techniques are used by between 200 and 500 million people worldwide.[1] Older English terms for slash and burn include assarting, swidden, and fire-fallow cultivation. Slash and burn is a specific functional element of certain farming practices, often shifting cultivation systems. In some cases such as parts of Madagascar, slash and burn may have no cyclical aspects (e.g., some slash and burn activities can render soils incapable of further yields for generations), or may be practiced on its own as a single cycle farming activity with no follow on cropping cycle. Shifting cultivation normally implies the existence of a cropping cycle component, whereas slash-and-burn actions may or may not be followed by cropping.
