Cobb's Wren
Cobb's wren (''Troglodytes cobbi'') is a fairly small (12-13.5 cm) wren which is endemic to the Falkland Islands. It was formerly classified as a subspecies of the house wren (''Troglodytes aedon'') but is now commonly considered to be a separate species due to differences in plumage, voice, ecology and morphology. The scientific and common names commemorate Arthur Cobb, an author from the Falkland Islands. Description The plumage is brown, greyer on the head and breast and more rufous on the tail. There are dark bars on the flight feathers and tail. The bill is long, blackish and slightly curved. The main confusion species is the sedge wren which is smaller with a shorter bill, buff eyestripe and dark streaks on the back and head. Cobb's wrens have a number of buzzing calls and their song is a series of jumbled trills and whistles. The song can be heard from August to February and varies between individuals with different males having different song patterns. Behaviour Th ...

Kelp
Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant - it is a heterokont, a completely unrelated group of organisms. Kelp grows in "underwater forests" ( kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago. The organisms require nutrient-rich water with temperatures between . They are known for their high growth rate—the genera '' Macrocystis'' and '' Nereocystis'' can grow as fast as half a metre a day, ultimately reaching .Thomas, D. 2002. ''Seaweeds.'' The Natural History Museum, London, p. 15. Through the 19th century, the word "kelp" was closely associated with seaweeds that could be burned to obtain soda ash (primarily sodium carbonate). The seaweeds used included species from both the orders Laminariales and Fucales. The word "kelp" was also used directly to refer to these processed ashes. Description In most ...

Troglodytes (bird)
''Troglodytes'' is a genus of small passerine birds in the wren family. These wrens are around long. They are brownish above and somewhat paler below, with strong legs. Their short rounded wings and frequently cocked tail have a dark barred pattern. The flight is direct and buzzing. ''Troglodytes'' wrens are mostly found in somewhat cooler habitats than most of their relatives. Most of the species are found in the mountains from Mexico to northern South America. Five species are found in temperate latitudes: The house wren occurs widely in both tropical and temperate lowlands, but is frequently split into several species. Until recently, the hardy winter wren was believed to have a wide distribution in North America, Europe, Asia and North Africa, but it has recently been split into three species, of which the Eurasian wren is the only wren of any genus found outside the New World. The Cobb's wren of the Falkland Islands is another species which tolerates harsh conditions w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Christopher Helm Publishers
A & C Black is a British book publishing company, owned since 2002 by Bloomsbury Publishing. The company is noted for publishing ''Who's Who'' since 1849. It also published popular travel guides and novels. History The firm was founded in 1807 by Charles and Adam Black in Edinburgh. In 1851, the company purchased the copyrights to Sir Walter Scott's ''Waverly'' novels for £27,000. The company moved to the Soho district of London in 1889. During the years 1827–1903 the firm published the seventh, eighth and ninth editions of the ''Encyclopædia Britannica''. This was purchased from Archibald Constable after his company's failure to publish the seventh edition of the encyclopedia. Adam Black retired in 1870 due to his disapproval of his sons' extravagant plans for its ninth edition. This edition, however, would sell half a million sets and was released in 24 volumes from 1875 to 1889. Beginning in 1839, the firm published a series of travel guides known as ''Black's Guide ...

Least-concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluat ...

Amphipod
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as '' Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tussac Grass
''Poa flabellata'', commonly known as tussac grass or just tussac, is a tussock grass native to southern South America, the Falkland Islands, South Georgia and other islands in the South Atlantic. There are also two isolated records from the herbarium at the French Muséum national d'histoire naturelle for the Île Amsterdam in the Indian Ocean. It was introduced to Shetland, Scotland for basket making in 1844, and possibly as a source of fodder because of its ability to grow in hostile conditions.. It grows in dense clumps, usually about high (although they can be much taller), on wet coastal land and is a dominant feature of much of the landscape. Associated organisms The plant community dominated by ''P. flabellata'' is widely used by birds and mammals. Breeding colonies of southern fur seal, elephant seal, Magellanic penguin, macaroni penguin, and albatrosses are all found amongst tussac grass on South Georgia and elsewhere. The austral thrush is predominantly fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
