Outstanding ecosystems

Wondermondo is proud to introduce to a list which is something unique by itself - a list of 66 unique and unusual ecosystems of the world. As always, this list is not exhaustive and any interested person would add here ecosystems to his own likings. But ecosystems listed below are by no means unique:

Isolated from the sea 12,000 years and contains a distinct population of two species of jellyfish - endemic Mastigias sp. and most likely endemic Aurelia sp. Millions of these jellyfishes make strict daily migration around the lake. Several more similar lakes in nearby islands but Jellyfish Lake is the only one open to tourists.
  • Lord Howe Island – Australia. This remote, 56 square kilometres large Australian island has its own ecoregion where half of plants and some birds and other animals are endemic. Unique characteristics is diverse glowing mushrooms in the forest, some bright enough to be used for reading in night. Endemic kentia palms are popular, beautiful houseplants.

  • Wooramel Seagrass Bank – Western Australia, Shark Bay. Largest seagrass grove in the world, covers 1,030 square kilometres.

Antarctica

  • Geothermal areas of Cryptogam Ridge - Antarctica. Here geothermal heat has been keeping ice-free areas of soil. Over the time in this isolated area have developed endemic species of microorganisms, as well as mosses and liverworts.
  • Lake Vostok - Antarctica. Largest subglacial lake in Antarctica, similar in size to Lake Ontario, up to 1 kilometre deep, with area 15,000 km2. Lake water is oversaturated with oxygen, exceeding the level of oxygen in ordinary freshwater lakes 50 times. Lake has been frozen for half a million years at least and here most likely has been developed unique habitat of microorganisms. This habitat has not been reached and investigated yet.
  • Penguin colony of Lusitania Bay - Australia, Macquarie Island. This subantarctic island has several endemic plant and animal species and unusually looking biotopes of megaherbs. But especially impressive is the giant colony of royal penguins (Eudyptes schlegeli Finsch.) - the island is the only known breeding ground of these beautiful birds. Lusitania Bay colony recently has been fully occupied and penguins are coming to other parts of island as well. In total it is estimated that there are 0.5 - 3 million penguins breeding in this island.

Oceans

  • Kairei hydrothermal vents - Indian ocean, Central Indian Ridge, circa 2,420 m deep. Group of hydrothermal vents with very high H2 concentration. It is possible that the unique ecosystem around these vents closely resembles the ancient ecosystems (consisting mainly of microorganisms) which existed on Earth in the seas before the photosynthesis process started. This unique ecosystem exists due to specific geological conditions around the vents. Here lives also a unique gastropod with shell made of iron oxides.
  • Lost City - Atlantic ocean, Atlantis Massif. Unique field of black smokers - hydrothermal vents with some 30 calcium carbonate towers - each 30 - 60 meters tall. Vents release methane and hydrogen, what makes them different from other known black smokers. One of most unique ecosystems of microorganisms developed in abiotic conditions.
