Arctic seas contain seasonal [[sea ice]] in many places. The Arctic region is a unique area among Earth's ecosystems.

An example of a dwarf shrub is the [[bearberry]]. As one moves northward, the amount of warmth available for plant growth decreases considerably. In the northernmost areas, plants are at their metabolic limits, and small differences in the total amount of summer warmth make large differences in the amount of energy available for maintenance, growth, and reproduction. Colder summer temperatures cause the size, abundance, productivity, and variety of plants to decrease. Trees cannot grow in the Arctic, but in its warmest parts, shrubs are common and can reach {{cvt|2|m|ftin}} in height; [[Cyperaceae|sedges]], mosses and lichens can form thick layers. In the coldest parts of the Arctic, much of the ground is bare; [[non-vascular plant]]s such as lichens and mosses predominate, along with a few scattered grasses and [[forb]]s (like the [[Papaver radicatum|Arctic poppy]]). === Animals === {{see also|List of Arctic cetaceans}}{{Category see also|Fauna of the Arctic|Mammals of the Arctic}} [[File:Muskus.jpg|thumb|[[Muskox]]]] [[File:Snowy Owl Portrait.jpg|thumb|upright|A [[snowy owl]]]] Herbivores on the tundra include the [[Arctic hare]], [[lemming]], [[muskox]], and [[reindeer]] (caribou). They are preyed on by the [[snowy owl]], [[Arctic fox]], [[grizzly bear]], and [[Arctic wolf]]. The [[polar bear]] is also a predator, though it prefers to hunt for marine life from the ice. There are also many [[:Category: Birds of the Arctic|birds]] and marine species endemic to the colder regions. Other terrestrial animals include [[wolverine]]s, [[moose]], [[Dall sheep]], [[Stoat|ermines]], and [[Arctic ground squirrel]]s. Marine mammals include [[Pinniped|seals]], [[walrus]]es, and several species of [[cetacea]]n—[[baleen whale]]s and also [[narwhal]]s, [[orca]]s, and [[Beluga whale|belugas]]. == Natural resources == {{See also|Natural resources of the Arctic|Petroleum exploration in the Arctic}} There are copious [[Natural resources of the Arctic|natural resources in the Arctic]] (oil, gas, minerals, freshwater, fish, and, if the subarctic is included, forest) to which modern technology and the [[Arctic resources race|economic opening up of Russia]] have given significant new opportunities. The interest in the tourism industry is also on the increase. The Arctic contains some of the last and most extensive continuous [[wilderness]] areas in the world, and its significance in preserving [[biodiversity]] and [[genotype]]s is considerable. The increasing presence of humans fragments vital habitats. The Arctic is particularly susceptible to the abrasion of [[groundcover]] and to the disturbance of the rare breeding grounds of the animals that are characteristic of the region. The Arctic also holds 1/5 of the Earth's water supply.<ref>{{Cite web |last=Society |first=National Geographic |date=2016-10-06 |title=Arctic |url=http://www.nationalgeographic.org/encyclopedia/arctic/ |access-date=2020-06-11 |website=National Geographic Society |archive-date=3 June 2020 |archive-url=https://web.archive.org/web/20200603203627/https://www.nationalgeographic.org/encyclopedia/arctic/ |url-status=live}}</ref> ==Paleontology== During the [[Cretaceous|Cretaceous period]], the Arctic still had seasonal snows, though only a light dusting and not enough to permanently hinder plant growth. Animals such as the ''[[Chasmosaurus]]'', ''[[Hypacrosaurus]]'', ''[[Troodon]]'', and ''[[Edmontosaurus]]'' may have all migrated north to take advantage of the summer growing season, and migrated south to warmer climes when winter came. A similar situation may also have been found amongst [[dinosaur]]s that lived in [[Antarctic]] regions, such as the ''[[Muttaburrasaurus]]'' of Australia.
