Cyclura Cychlura Figginsi
''Cyclura cychlura figginsi'', known by the common name of guana and sometimes called the Exuma Island iguana in the international literature, is a subspecies of the northern rock iguana, northern Bahamian rock iguana, ''C. cychlura'', that is found on the Exuma island chain in the Bahamas with an estimated wild population of 1,300 animals in 2004, it has been listed on the IUCN Red List as Critically endangered species, critically endangered. Taxonomy ''Cyclura cychlura figginsi'' is a subspecies of the northern Bahamian rock iguana, ''Cyclura cychlura''. Its subspecies, subspecific name commemorates the American biologist J. D. Figgins. In the late 19th century the American naturalist Charles Johnson Maynard mentioned that populations of iguanas still existed on the small island Bitter Guana Cay, being the namesake of the toponym, and he also mentioned that he thought it was possible this population could be named as a new species. In 1923 Thomas Barbour obliged. In 1975 Alber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Barbour
Thomas Barbour (August 19, 1884 – January 8, 1946) was an American herpetologist. He was the first president of the Dexter School in 1926. From 1927 until 1946, he was director of the Harvard Museum of Comparative Zoology (MCZ) founded in 1859 by Louis Agassiz at Harvard University in Cambridge, Massachusetts. Life and career Barbour, the eldest of four brothers, was born in 1884 to Colonel William Barbour, and his wife, Julia Adelaide Sprague. Colonel Barbour was founder and president of The Linen Thread Company, Inc., a successful thread manufacturing enterprise having much business in the United States, Ireland, and Scotland. Although born on Martha's Vineyard, Massachusetts, where the family was spending the summer, Barbour grew up in Monmouth, New Jersey, where one of his younger brothers, William Warren Barbour, entered the political arena, eventually serving as U.S. Senator from New Jersey from 1931 to 1937 and again from 1938 to 1943. At age fifteen, Thomas Barbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berry
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit although many pips or seeds may be present. Common examples of berries in the culinary sense are strawberries, raspberries, blueberries, blackberries, white currants, blackcurrants, and redcurrants. In Britain, soft fruit is a horticultural term for such fruits. The common usage of the term "berry" is different from the scientific or botanical definition of a berry, which refers to a fleshy fruit produced from the ovary of a single flower where the outer layer of the ovary wall develops into an edible fleshy portion( pericarp). The botanical definition includes many fruits that are not commonly known or referred to as berries, such as grapes, tomatoes, cucumbers, eggplants, bananas, and chili peppers. Fruits commonly considered berries but excluded by the botanical definition include strawberries, raspber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf
A leaf (: leaves) is a principal appendage of the plant stem, stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the Shoot (botany), shoot system. In most leaves, the primary Photosynthesis, photosynthetic Tissue (biology), tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (Glossary of botanical terms#adaxial, adaxial) and lower (Glossary of botanical terms#abaxial, abaxial) surfaces that differ in color, Trichome, hairiness, the number of stomata (pores that intake and output gases), the amount and ...

Herbivore
A herbivore is an animal anatomically and physiologically evolved to feed on plants, especially upon vascular tissues such as foliage, fruits or seeds, as the main component of its diet. These more broadly also encompass animals that eat non-vascular autotrophs such as mosses, algae and lichens, but do not include those feeding on decomposed plant matters (i.e. detritivores) or macrofungi (i.e. fungivores). As a result of their plant-based diet, herbivorous animals typically have mouth structures ( jaws or mouthparts) well adapted to mechanically break down plant materials, and their digestive systems have special enzymes (e.g. amylase and cellulase) to digest polysaccharides. Grazing herbivores such as horses and cattles have wide flat- crowned teeth that are better adapted for grinding grass, tree bark and other tougher lignin-containing materials, and many of them evolved rumination or cecotropic behaviors to better extract nutrients from plants.

Cyclura
''Cyclura'' is a genus of lizards in the family Iguanidae. Member species of this genus are commonly known as "cycluras" (or more commonly as rock iguanas) and only occur on islands in the West Indies. Rock iguanas have a high degree of endemism, with (in most cases) a single species or subspecies originating on an individual island. Taxonomy The genus ''Cyclura'' was first circumscribed by Richard Harlan in 1825 to include two new species of lizard: ''C. carinata'' and ''C. teres''. ''C. teres'' eventually turned out to be a junior synonym of '' Ctenosaura acanthura''. In the 20th century there were eight recognised species of ''Cyclura'' and nine additional subspecies (one extinct) besides the nominotypical subspecies. Recently, certain subspecies were elevated to species status. Currently, there are ten species in this genus. Habitat Rock iguanas most often inhabit subtropical zones, of Caribbean island dry forest biomes. These landscapes are characterised b ...

Bahamian Dry Forests
The Bahamian dry forests are a tropical and subtropical dry broadleaf forest ecoregion in the Bahamas and the Turks and Caicos Islands, covering an area of . They are found on much of the northern Bahamas, including Andros, Abaco, and Grand Bahama, where they are known as coppices. Dry forests are distributed evenly throughout the Turks and Caicos. Whiteland coppice Whiteland coppices are shrubby forests that occur near the ocean. Vegetation occurring in whiteland coppice is able to withstand salt spray and rocky, calcareous soil. Trees that grow in whiteland coppices include cinnecord (''Acacia choriophylla''), brasiletto ('' Caesalpinia vesicaria''), haulback tree ('' Mimosa bahamensis''), autograph tree ('' Clusia rosea''), manchineel tree (''Hippomane mancinella''), West Indian mahogany ('' Swietenia mahagoni''), sea grape (''Coccoloba uvifera''), gumbo-limbo (''Bursera simaruba''), cabbage palmetto (''Sabal palmetto''), and poisonwood (''Metopium toxiferum'').

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Exuma Cays
Exuma is a district of The Bahamas, consisting of over 365 islands and cays. The largest of the islands is Great Exuma, which is 37 mi (60 km) in length and joined to another island, Little Exuma, by a small bridge. The capital and largest town in the district is George Town (population 1,437). It was founded 1793 and located on Great Exuma. Near the town, but on Little Exuma, the Tropic of Cancer runs across Pelican Beach lending it another name: Tropic of Cancer Beach. Its white sand and turquoise waters make it a world-famous destination. The entire island chain is 130 mi (209 km) long and 72 sq mi (187 km²) in area. Great Exuma island has an area of 61 sq mi (158 km²) while Little Exuma has an area of 11 sq mi (29 km²). Between 2000 and 2010, the population of Exuma more than doubled, reflecting the construction of large and small resort properties and the related direct air traffic to Great Exuma from locations as distant as Toronto, Canada. The population in 2010 was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
