Can alligators go in the ocean?
Alligators are primarily freshwater animals and they do not live in the ocean. While alligators can tolerate salt water for a few hours or even days, they are primarily freshwater animals, living in swampy areas, rivers, streams, lakes, and ponds.
What was it like in the Arctic 50 million years ago?
The climate was very different back then, with winter temperatures hovering at or just above freezing, and summer temperatures in the 70s. Of course, any Ellesmere Island residents alive at the time would have still coped with months of total darkness in the wintertime, and perpetual sun in the summer.
What kind of animals live in the Arctic tundra?
Sometimes, migration is the best strategy. For example, caribou migrate across the Arctic tundra to make use of different resources according to the seasons. Marine mammals, such as whales, migrate north when the ice clears to feed on the rich plankton of the cold Arctic waters.
What kind of birds live in the Arctic?
Arctic Terns may migrate farther than any other birds, going from the high Arctic to the Antarctic. Most birds in the Arctic are migratory. Landbirds comprise more than 50% of the bird species in Arctic parklands.
Where do mountain goats live in the tundra?
The mountain goats are the largest animals occasionally found at altitudes above 13,000 feet and usually live above the tree line in their habitat. These animals are herbivorous in nature and spend a significant amount of time grazing in the alpine meadows.
What’s the weather like in the Arctic tundra?
Almost there are two seasons in the tundra. Winter and summer season. In winter temperature degree falls to 34° C (-30° F). which is really tough weather for most plants. while in summer the average temperature is 3-12° C (37-54° F). Rains in the tundra are rare, almost like a desert.
How did alligators live in the High Arctic?
“This is arguably the most comprehensive data set for the early Eocene High Arctic, and certainly explains how alligators and giant tortoises could live on Ellesmere Island some 52 to 53 million years ago,” said Eberle. Eberle explained that fossilized bones and tooth enamel contain biogenic apatite — a mineral that is fossilized after death.
Are there any people living in the Arctic tundra?
Not many people are able to live in the arctic tundra, especially areas of the habitat that lie closer to the north pole. In certain areas of Alaska and Canada there are rather large settlements of humans. The arctic tundra also has a rich history for the aboriginal people of North America because the tundra is home to the Inuit peoples.
Where is the Arctic tundra located in the world?
Location: The arctic tundra can be found in the northern parts of North America, Europe, and Asia. Most of the region is found within the Arctic Circle and above the edge of the coniferous forests—latitude 60°N in Canada and Siberia and latitude 70°N in the other countries.
How are plants able to survive in the Arctic tundra?
Most of the flowers that survive in the tundra are perennials; they lay dormant in the cold winters and grow again from the same roots in the summer. The ground of the arctic tundra is marshy and boggy during the summer, so plants must be able to survive in water-logged areas.
