Laminaria Nigripes
''Laminaria nigripes'' is a species of kelp found in the North Atlantic and North Pacific within Arctic and subarctic waters including Vancouver Island, Haida Gawaii, Greenland, Iceland, Norway, Downeast Maine, and the Bay of Fundy. The species may be found exclusively in the Arctic, but frequent misidentification of samples has led to speculation and debate over whether the actual range is subarctic or Arctic. The species is commonly confused with ''Laminaria digitata'' and ''Laminaria hyperborea'' and is at risk from climate change. Phylogony ''Laminaria nigripes'' is a species within the genus Laminaria. The genus Laminaria is in the family Laminariaceae which is one of eight families in the order of Laminariales. The class of Phaeophyceae includes the order of Laminariales. Phaeophyceae are brown algae commonly referred to as kelp. ''Laminaria nigripes'' was first described in 1868 under the name '' Saccharina nigripes'' by Jacob Agardh in Spitsbergen, Norway.

Laminaria Digitata Free
''Laminaria'' is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. This economically important genus is characterized by long, leathery laminae and relatively large size. Some species are called Devil's apron, due to their shape, or sea colander, due to the perforations present on the lamina. Others are referred to as ''tangle''. ''Laminaria'' form a habitat for many fish and invertebrates. The life cycle of ''Laminaria'' has heteromorphic alternation of generations which differs from ''Fucus''. At meiosis the male and female zoospores are produced separately, then germinate into male and female gametophytes. The female egg matures in the oogonium until the male sperm fertilizes it. Life-Cycle: The most apparent form of ''Laminaria'' is its sporophyte phase, a structure composed of the holdfast, the stipe, and the blades. While it spends its time predominately in the sporophyte phase, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Agarum Clathratum
Agarum (also transliterated as Agaru or Akarum, cuneiform: ''a-kà-rum'' or ''a-ga-rum'') is a bronze-age Near Eastern proper name, probably a toponym for a region or island in the Eastern Arabia and Persian Gulf. Agarum has been generally identified with Kuwait's Failaka Island, known as ´KR to the Arameans and as Ikaros during the Hellenistic times. Failaka's Ekara temple is another probable location.Glassner 1988, pp. 240-243. Agarum is sometimes identified with the mediaeval city of Haǧar, in the general region of Al-Ahsa Oasis in Saudi Arabia and Bahrain Island in Bahrain. The name Agarum is attested in the earlier half of the 2nd millennium BCE, mentioned in inscriptions of the ancient Dilmun civilization (modern-day Bahrain). Agarum was associated with Inzak, the chief deity of Dilmunite pantheon. Several Dilmunite kings styled themselves as "servants of the Inzak of Agarum"; such kings included Rimum (c. 18th century BCE), Yagli-El (c. 18th and 17th centuries BCE), and ...

Saccharina Latissima
''Saccharina latissima'' is a brown alga (class Phaeophyceae), of the family Laminariaceae. It is known by the common names sugar kelp, sea belt, and Devil's apron, and is one of the species known to Japanese cuisine as kombu. It is found in the north Atlantic Ocean, Arctic Ocean and north Pacific Ocean. It is common along the coast of Northern Europe as far south as Galicia Spain, the coast of North America north of Massachusetts and central California, and the coast of Asia south to Korea and Japan. Description ''Saccharina latissima'' is a yellowish brown colour with a long narrow, undivided blade that can grow to long and wide. The central band is dimpled while the margins are smoother with a wavy edge, this is to cause greater water movement around the blades to aid in gas exchange. The frond is attached to the rock by stout rhizoids about 5 mm in diameter in the intertidal and sublittoral zones by a claw-like holdfast and a short, pliable, cylindrical stipe.
