In physical geography, tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра from the Kildin Sami word tūndâr "uplands," "treeless mountain tract."^[1] There are three types of tundra: Arctic tundra,^[2] alpine tundra,^[2] and Antarctic tundra.^[3] In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline.

Arctic[link]

Arctic tundra occurs in the far Northern Hemisphere, north of the taiga belt. The word "tundra" usually refers only to the areas where the subsoil is permafrost, or permanently frozen soil. (It may also refer to the treeless plain in general, so that northern Sápmi would be included.) Permafrost tundra includes vast areas of northern Russia and Canada.^[2] The polar tundra is home to several peoples who are mostly nomadic reindeer herders, such as the Nganasan and Nenets in the permafrost area (and the Sami in Sápmi).

Arctic tundra contains areas of stark landscape and is frozen for much of the year. The soil there is frozen from 25–90 cm (9.8–35.4 inches) down, and it is impossible for trees to grow. Instead, bare and sometimes rocky land can only support low growing plants such as moss, heath (Ericaceae varieties such as crowberry and black bearberry), and lichen. There are two main seasons, winter and summer, in the polar tundra areas. During the winter it is very cold and dark, with the average temperature around −28 °C (−18 °F), sometimes dipping as low as −50 °C (−58 °F). However, extreme cold temperatures on the tundra do not drop as low as those experienced in taiga areas further south (for example, Russia's and Canada's lowest temperatures were recorded in locations south of the tree line). During the summer, temperatures rise somewhat, and the top layer of the permafrost melts, leaving the ground very soggy. The tundra is covered in marshes, lakes, bogs and streams during the warm months. Generally daytime temperatures during the summer rise to about 12 °C (54 °F) but can often drop to 3 °C (37 °F) or even below freezing. Arctic tundras are sometimes the subject of habitat conservation programs. In Canada and Russia, many of these areas are protected through a national Biodiversity Action Plan.

Tundra in Alaska

The tundra is a very windy area, with winds often blowing upwards of 48–97 km/h (30–60 miles an hour). However, in terms of precipitation, it is desert-like, with only about 15–25 cm (6–10 inches) falling per year (the summer is typically the season of maximum precipitation). Although precipitation is light, evaporation is also relatively minimal. During the summer, the permafrost thaws just enough to let plants grow and reproduce, but because the ground below this is frozen, the water cannot sink any lower, and so the water forms the lakes and marshes found during the summer months. There is a natural pattern of accumulation of fuel and wildfire which varies depending on the nature of vegetation and terrain. Research in Alaska has shown fire-event return intervals, (FRIs) that typically vary from 150 to 200 years with dryer lowland areas burning more frequently than wetter highland areas.^[4]

The biodiversity of the tundras is low: 1,700 species of vascular plants and only 48 land mammals can be found, although millions of birds migrate there each year for the marshes.^[5] There are also a few fish species such as the flatfish. There are few species with large populations. Notable animals in the Arctic tundra include caribou (reindeer), musk ox, arctic hare, arctic fox, snowy owl, lemmings, and polar bears (only the extreme north).^[6] Tundra is largely devoid of poikilotherms such as frogs or lizards.

Due to the harsh climate of the Arctic tundra, regions of this kind have seen little human activity, even though they are sometimes rich in natural resources such as oil and uranium. In recent times this has begun to change in Alaska, Russia, and some other parts of the world.

Relationship with global warming[link]

A severe threat to the tundras, specifically to the permafrost, is global warming. The melting of the permafrost in a given area on human time scales (decades or centuries) could radically change which species can survive there.^[7]

Another concern is that about one third of the world's soil-bound carbon is in taiga and tundra areas. When the permafrost melts, it releases carbon in the form of carbon dioxide and methane,^[8] both of which are greenhouse gases. The effect has been observed in Alaska. In the 1970s the tundra was a carbon sink, but today, it is a carbon source.^[9] Methane is produced when vegetation decays in lakes and wetlands.^[10]

The amount of greenhouse gases which will be released under projected scenarios for global warming have not been reliably quantified by scientific studies, although a few studies were reported to be underway in 2011. It is uncertain whether the impact of increased greenhouse gases from this source will be minimal or massive.^[10]

In locations where dead vegetation and peat has accumulated there is a risk of wildfire such as the 1,039 square kilometres (401 sq mi) of tundra which burned in 2007 on the north slope of the Brooks range.^[10] Such events may both result from and contribute to global warming.^[11]

[edit] Antarctic

Tundra on the Péninsule Rallier du Baty, Kerguelen Islands.

Antarctic tundra occurs on Antarctica and on several Antarctic and subantarctic islands, including South Georgia and the South Sandwich Islands and the Kerguelen Islands. Most of Antarctica is too cold and dry to support vegetation, and most of the continent is covered by ice fields. However, some portions of the continent, particularly the Antarctic Peninsula, have areas of rocky soil that support plant life. The flora presently consists of around 300–400 lichens, 100 mosses, 25 liverworts, and around 700 terrestrial and aquatic algae species, which live on the areas of exposed rock and soil around the shore of the continent. Antarctica's two flowering plant species, the Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis), are found on the northern and western parts of the Antarctic Peninsula.^[12]

In contrast with the Arctic tundra, the Antarctic tundra lacks a large mammal fauna, mostly due to its physical isolation from the other continents. Sea mammals and sea birds, including seals and penguins, inhabit areas near the shore, and some small mammals, like rabbits and cats, have been introduced by humans to some of the subantarctic islands. The Antipodes Subantarctic Islands tundra ecoregion includes the Bounty Islands, Auckland Islands, Antipodes Islands, the Campbell Island group, and Macquarie Island.^[13] Species endemic to this ecoregion include Nematoceras dienemum and Nematoceras sulcatum, the only Subantarctic orchids; the royal penguin; and the Antipodean albatross.^[13]

The flora and fauna of Antarctica and the Antarctic Islands (south of 60° south latitude) are protected by the Antarctic Treaty.^[14]

[edit] Alpine

Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. Alpine tundra is distinguished from arctic tundra in that alpine tundra typically does not have permafrost, and alpine soils are generally better drained than arctic soils. Alpine tundra transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as Krummholz.

Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by the low air pressure, and is similar to polar climate.

Climatic classification[link]

Tundra region with fjords, glaciers and mountains. Kongsfjorden, Spitsbergen.

Tundra climates ordinarily fit the Köppen climate classification ET, signifying a local climate in which at least one month has an average temperature high enough to melt snow (0°C or 32°F), but no month with an average temperature in excess of (10°C/50°F). The cold limit generally meets the EF climates of permanent ice and snows; the warm-summer limit generally corresponds with the poleward or altitudinal limit of trees, where they grade into the subarctic climates designated Dfd and Dwd (extreme winters as in parts of Siberia), Dfc typical in Alaska, Canada, European Russia, and Western Siberia (cold winters with months of freezing), or even Cfc (no month colder than -3°C as in parts of Iceland and southernmost South America). Tundra climates as a rule are hostile to woody vegetation even where the winters are comparatively mild by polar standards, as in Iceland.

Despite the potential diversity of climates in the ET category involving precipitation, extreme temperatures, and relative wet and dry seasons, this category is rarely subdivided. Rainfall and snowfall are generally slight due to the low vapor pressure of water in the chilly atmosphere, but as a rule potential evapotranspiration is extremely low, allowing soggy terrain of swamps and bogs even in places that get precipitation typical of deserts of lower and middle latitudes. The amount of native tundra biomass depends more on the local temperature than the amount of precipitation.

Economy[link]

Human economic activity has been scarce on tundras. Hunting and trapping reindeer have provided food and hides to the local population. Occasional mineral resources, such as fossil fuel and ores occasionally appear in tundras. Difficultues of prospecting, mining and transportation have held back exploitation of these resources until modern times.

The Mighty Boosh is a British comedy troupe featuring comedians Julian Barratt and Noel Fielding. Developed from 3 stage shows and a 6-episode radio series, it has since spawned a total of 20 television episodes for BBC Three and 2 live tours of the UK, as well as 2 live shows in the United States.

History[link]

Fielding first met Barratt after seeing him perform his solo stand-up routine at the Hellfire Comedy Club in the Wycombe Swan Theatre.^[1] The pair soon found that they shared comic interests, formed a double act, and "decided to be the new Goodies".^[2] After their first performance together at a bar in London in April 1998, Barratt and Fielding developed their zookeeper characters--Howard Moon and Vince Noir, respectively--in a series of sketches for Paramount Comedy’s Unnatural Acts. Here they also met American Rich Fulcher, who became Bob Fossil. Fielding’s friend Dave Brown and Fielding's brother Michael also became regular collaborators. Richard Ayoade was another original cast member, playing adventurer Dixon Bainbridge, but Matt Berry replaced him in the first television series, since Ayoade was under contract with Channel 4.^[3] Ayoade returned in the second and third series as a belligerent shaman named Saboo.

According to Michael Fielding, the name "Mighty Boosh" was originally a phrase used by a Spanish friend to describe the curly hair that Michael had as a child.^[4]

The Boosh produced 3 stage shows--The Mighty Boosh (1998), Arctic Boosh (1999) and Autoboosh (2000)--all of which were taken to the Edinburgh Fringe. With the success of Autoboosh, a radio series was commissioned by the BBC. Produced by Danny Wallace, The Boosh was first broadcast in 2001 on BBC London Live, later transferring to BBC Radio 4, from which the team were given a half-hour television pilot of the same name.

The first 8-part series, directed by Paul King, was then commissioned for BBC Three and broadcast in 2004, with a second of 6 episodes the next year. The second series moved away from the zoo setting to show Howard, Vince, Naboo the shaman and Bollo the talking ape living in a flat in Dalston.^[5] In 2006, the Boosh returned to theatre with The Mighty Boosh Live, which featured a new story entitled "The Ruby of Kukundu".

After two years away from television, the Boosh returned in November 2007. Set in Naboo’s second-hand shop below the flat, the third series drew approximately 1 million viewers with its first episode,^[6] and in light of its success, BBC Three broadcast an entire night of The Mighty Boosh on 22 March 2008, which included a new documentary and 6 of Barratt and Fielding's favourite episodes from all 3 series.

Theatre[link]

Original stage shows[link]

[edit] The Mighty Boosh (1998)

The Boosh, then consisting of only Barratt and Fielding, conceived The Mighty Boosh whilst working on Stewart Lee's Edinburgh Festival show King Dong vs. Moby Dick in which they played a giant penis and a whale respectively.

In 1998, they took The Mighty Boosh to the Edinburgh Festival, recruiting fellow comedian Rich Fulcher, whom the pair had met while working on Unnatural Acts. The show won the Perrier Award for Best Newcomer. During their residency at North London's Hen and Chickens Theatre the following year, they built up a cult following, introducing new characters whilst developing old ones.

[edit] Arctic Boosh (1999)

In 1999, the Boosh returned to the Edinburgh Festival with a new show, Arctic Boosh, with Dave Brown acting as choreographer and photographer, as well as playing a variety of characters. Arctic Boosh sold out every night and was nominated for the Perrier Award.

[edit] Autoboosh (2000)

In 2000, the Boosh premiered their third stage show, Autoboosh, at the Melbourne International Comedy Festival, adding Fielding's younger brother Michael to the cast. Autoboosh won the festival's Barry Award.

Nationwide tours[link]

[edit] The Mighty Boosh Live (2006)

The Boosh returned to the stage in 2006, touring the UK for the first time. Though drawing heavily from their earlier material, the main story combined these elements into a new narrative. A recording of this show at the Brixton Academy was later released on DVD, before being broadcast on BBC Three on Boxing Day, 2007.

[edit] Boosh Live: Future Sailors Tour (2008/09)

The Boosh toured the UK and Ireland for a second time from September 2008 to February 2009. The show featured characters from all three series as well as the Boosh Band.

They made appearances throughout the UK after their live shows, at after-parties held in different places in each city. The events were called "Outrage", after the catchphrase by Tony Harrison.

Radio[link]

[edit] The Boosh (2001)

From the success of Autoboosh, the BBC commissioned a 6-part radio series for the Boosh. In October 2001 The Boosh radio series, produced by Danny Wallace, was broadcast on BBC London Live, then BBC Radio 4, and later on BBC 7. The show focuses on the adventures of a pair of zookeepers at "Bob Fossil's Funworld": socially awkward, jazz enthusiast Howard TJ Moon, and ultra-vain, fashion-obsessed Vince Noir. This also included voices from Lee Mack also, playing such characters as the Plumber or the Gardener.

Further appearances[link]

The Mighty Boosh returned to radio on 22 October 2004, in a one-off comedy special for The Breezeblock, a show on BBC Radio 1.^[7] Instead of the plot driven nature of their own series, this show featured improvised conversational comedy with Barratt, Fielding and Fulcher, combined with the show's usual mix of electronic music.

On 15 November 2007, as part of the publicity for the premier of their third series the same day, Julian Barratt and Noel Fielding returned to Radio 1, this time on Jo Whiley's Live Lounge.^[8]

Television[link]

In May 2004, after the success of a Boosh pilot, Steve Coogan's company, Baby Cow Productions, produced the first television series of The Mighty Boosh for BBC Three, before it moved to BBC Two in November that same year. Though each episode invariably starts and ends in Dixon Bainbridge’s dilapidated zoo, the "Zooniverse", the characters of Vince and Howard often depart for other locations, such as the Arctic tundra and limbo.

A second series, shown in July 2005, saw Howard and Vince sharing Naboo's flat in Dalston with previously minor characters Naboo and his familiar, Bollo, a gorilla living at the "Zooniverse". This series had an even looser setting as the 4 characters leave the confines of the flat in every episode, travelling in their van to a variety of surrealistic environments, including Naboo's home planet "Xooberon".

Series three started in November 2007, still set in Dalston, but this time the foursome are selling 'Bits & Bobs' in their shop, the Nabootique. Their adventures and outings in this series focused more on the involvement of new characters (e.g. Sammy the Crab, or Lester Corncrake etc.) rather than just the two of them.

Although BBC America originally aired only series 1 in the U.S (all episodes in their entirety), The Mighty Boosh began airing in North America on Cartoon Network's Adult Swim block (with up to 6 minutes cut from each episode), starting 29 March 2009 with the third series.^[9]

[edit] The Mighty Boosh Night

On 22 March 2008, BBC Three broadcast a whole night of The Mighty Boosh from 9.05 pm, starting with a new documentary entitled The Mighty Boosh: A Journey Through Time and Space, documenting the history of the Boosh from their first amateur performances to their then-upcoming 2008 tour. This was followed by six of Barratt and Fielding's favourite episodes from the three series: "Party", "The Power of the Crimp", "The Nightmare of Milky Joe", "The Priest and the Beast", "The Legend of Old Gregg", and "Tundra". The pair also appeared in live links throughout the night, in a similar style to the openings of Series 1 episodes. On 23 December 2008, BBC3 held a Merry Booshmas Party featuring the entire series 3 as well as a broadcast of The Mighty Boosh Live.^[10]

Film[link]

On 8 February 2012, Noel Fielding said that he and Barratt had discussed plans to make a Mighty Boosh film, whilst sledging.^[11]

Festival[link]

On 5 July 2008, the Boosh held their own festival in the Hop Farm in Kent. It featured musical acts, Robots in Disguise, The Charlatans, The Kills, Gary Numan, and The Mighty Boosh Band, as well as comedy acts Frankie Boyle and Ross Noble.

Media[link]

Audio CDs[link]

According to an official MySpace page for PieFace Records (the fictitious music label mentioned throughout the series), Barratt and Fielding are to release an album of music from the show, "along with extras, versions, remixes and rare unreleased stuff all to be released later in the year on their own label--this one".^[12] In interviews since, The Mighty Boosh have confirmed they will be releasing an album of their music.^[13] On the 21 October^[when?] episode of Never Mind the Buzzcocks, Fielding stated that the Boosh have recorded an album, but don't know when it will be released.

DVDs[link]

Previously most of the DVDs were only released in Region 2 but as a result of a growing fan base in the U.S., the BBC rereleased in Region 1, Series 1-3 individually on 21 July 2009,^[14][15] and a Special Edition Series 1-3 Boxset on 13 October 2009.^[16]

Books[link]

On 18 September 2008, Canongate Books published The Mighty Book of Boosh, designed and compiled by Dave Brown and written by Noel Fielding, Julian Barratt, Rich Fulcher, Dave Brown, Richard Ayoade and Michael Fielding. The book includes original stories, crimps, concept art, behind-the-scenes photography, comics, and various other things, featuring old and new Mighty Boosh characters. On 1 October 2009, a paperback version was released under the name The Pocket Book of Boosh.

Awards[link]

Particularly popular among followers of the indie and electro music genres which the NME magazine caters to, The Mighty Boosh has been recipient of the Shockwaves NME Awards Best TV Show for three consecutive years, even though there were no new episodes broadcast for the latter two of the three years.
