Polar bear Ursus maritimus or the "sea bear." Polar bears live near the circumpolar at north in areas where they can hunt seals at open leads. Scientists estimate that there are between 22000 to 27000 polar bears. Its closest relative is the brown bear. Adult male polar bears are 2,5 to 3 meters tall. They weigh 250 to 770 kilograms. Adult female bears are smaller. They are about 1,8 to 2,5 meters tall and weigh 90 to 320 kilograms. Polar bears usually eat seals ­ usually the ringed seasl, but sometimes the bearded seals. When hunting is good, polar bears will typically eat only the fat and leave the rest of the carcass for scavengers including arctic foxes, ravens, and younger bears. Polar bears also sometimes kill and eat both walrus and beluga whales. They have even hunted short-legged reindeer and sometimes even birds and bird eggs.

Tundra

Tundra Tundra is the world's youngest biome. It was formed 10 000 years ago. Located at latitudes 55° to 70° North. Almost all tundras are located in the Northern Hemisphere, encircling arctic desert and extending south to the coniferous forests of the taiga. The ecotone (ecological boundary region) between the tundra and the forest is known as the tree line or timberline. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-moulded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation.

Gröönimaast - kokkuvõte

Risto Isomäki ökopõnevik "Sarasvati liiv" kirjeldab, kuidas hukkus veeuputuses tegelik Atlantis ning tekib uus üleilmne veeuputus. Atlantis asus India veerel, aga uus uputus tekib Gröönimaa jääliustike vettekukkumise tagajärjel. Hamburg täitub veega, nii et vaid kõrghoonete antennid ulatuvad sealt välja. 1984. aastal ühines Eesti Põhja-Euroopa ja Gröönimaa merikotka kaitse programmiga. LISA: Valdavalt elavad siinsetel aladel ka saare taimtoidulised loomad, kellest levinumad on Põhja- Ameerikast pärit musksusveis ja karibu. Gröönimaal elutsevad ka väike näriline lemming, valgejänes, kärp, polaarrebane ning loomulikult ka jääkaru.
