Woody species such as the Arctic Willow assume a ground-hugging form. A great amount of species circulate throughout the Arctic to feed, mate, give birth, take care of their young and moult.
Increased shipping in the Arctic may pose a potential threat to the Arctic ecosystem and on the population of species.
The Arctic contains a vast flora of shrubs, grasses, and wildflowers and these plants play an important role in the region’s carbon cycle. The Arctic poppy (Papaver laestadianum) is a rare, endemic, perennial plant species found only in the harsh, Arctic conditions of the northernmost parts of Scandinavia. Nearly all species are perennial because too little energy is received for plants to germinate, bloom, and produce seeds during one brief summer. Detailed information about eight plant species that are found on the Arctic tundra. This theory was proven by the extreme abundance of lemmings (small rodent species) during the peak season of their population cycle which… However, the plant kingdom also includes mosses, liverworts, and hornworts, simpler plants that lack these water-transporting structures.
Arctic plants have developed numerous adaptations to this harsh ecosystem. An overview of Arctic plant adaptations. Arctic Ecosystem Arctic ecosystems are likely to remain sources of CO2 to the atmosphere for some time before the effects of climate change can stimulate ecosystem-level productivity sufficiently to counteract this loss. “Species of the Arctic play a much more dominant role in the trophic dynamics of ecosystems in the Arctic than do species in the highly complex temperate and tropical ecosystems (Britannica, 2014 )”. Animals such as caribou, reindeer, arctic hare, lemmings and musk oxen are the primary consumers on the arctic tundra, while arctic fox, snowy owls, polar bears and wolves are the primary predators. This region is characterized by stressful conditions as a result of extreme cold, low precipitation, a limited growing season (50–90 days) and virtually no sunlight throughout the winter. This process makes the ecosystem keep going with animals dying while more are being reborn. Within the cup-shaped flower are five stigma protruding from a flat disk. A defining characteristic of plants is their ability to produce energy through photosynthesis. The arctic region is predicted to experience the earliest and most pronounced global warming response to human-induced climatic change. To avoid the chilling arctic winds, most plants are very short. The Arctic Ocean, although the smallest and shallowest of the world's five major oceans, is made up of thousands of organisms, approximately 1,700 of those species being Arctic plants. Arctic ecology is the scientific study of the relationships between biotic and abiotic factors in the arctic, the region north of the Arctic Circle (66 33’). The Arctic Ocean Ecosystem: The Food Web . Grow Low, Grow Fast, Hold On! See more ideas about Arctic habitat, Animal habitats and Ecosystems projects. BBC Studios 235,408 views But with a regular temperature reaching near freezing and limited sunlight, only certain plants and animals can survive in the Arctic Ocean. How the fig tree strangles other plants for survival in the rainforest - David Attenborough - BBC wildlife - Duration: 3:40.
Nov 12, 2014 - Explore elvita3's board "Arctic ecosystem" on Pinterest. These primary predators eat the primary consumers. Plants of Antarctica An overview of the species found in Antarctica. The Arctic habitat is a very cold place at the top of the world where some plants and animals live, and is made up of the Arctic Ocean, icy glaciers and tundra, or flat plains with no trees. The Arctic spans northern regions of Alaska, Canada, Russia, Greenland, Iceland, Norway and Sweden. But a number of animal species and Arctic plants have adapted to not just survive but thrive here, with more migrating to take advantage of the brief but glorious Arctic summer, six to eight weeks of endless sunlight, growth and bounty. It has a complex but abundance ecosystem that supports large predators such as walruses, polar bears and whales.
The solitary flower head consists of four vibrant yellow petals, supported by an erect stem which is long and narrow and has thick, spreading black hairs.
