Chatham Albatross
The Chatham albatross (''Thalassarche eremita''), also known as the Chatham mollymawk or Chatham Island mollymawk,Robertson, C. J. R. (2003) is a medium-sized black-and-white albatross which breeds only on The Pyramid, a large rock stack in the Chatham Islands, New Zealand. It is sometimes treated as a subspecies of the shy albatross ''Thalassarche cauta''. It is the smallest of the shy albatross group. Taxonomy Mollymawks are a type of albatross that belong to family Diomedeidae of the order Procellariiformes, along with shearwaters, fulmars, storm petrels, and diving petrels. They share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the albatross are on the sides of the bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates. Finally, they produce a stomach oil made up of wax esters and triglycerides that is stored in the prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Cushman Murphy
The whaling ship, ''Daisy'', which Murphy traveled on to the Antarctic Robert Cushman Murphy (April 29, 1887 – March 20, 1973) was an American ornithologist and Lamont Curator of birds at the American Museum of Natural History. He went on numerous oceanic expeditions and was an expert on marine birds, and wrote several major books on them. He described a species of petrel which is now known as Murphy's petrel. Mount Murphy in Antarctica and Murphy Wall in South Georgia are named after him. Life and work Murphy was born in Brooklyn, New York, to Thomas D. Murphy and Augusta Cushman. Around 1906 Murphy assisted Frank Chapman at the American Museum of Natural History and read the proofs of ''Warblers of North America''. He was an undergraduate at Brown University, where he graduated in 1911. He married Grace Alice Bairstow in 1911 who he met as a student at Brown University. Grace persuaded Robert to take a position as naturalist aboard the whaling ship ''Daisy''. After their w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triglycerides
A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from ''tri-'' and ''glyceride''). Triglycerides are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat. They are also present in the blood to enable the bidirectional transference of adipose fat and blood glucose from the liver, and are a major component of human skin oils. Many types of triglycerides exist. One specific classification focuses on saturated and unsaturated types. Saturated fats have ''no'' C=C groups; unsaturated fats feature one or more C=C groups. Unsaturated fats tend to have a lower melting point than saturated analogues; as a result, they are often liquid at room temperature. Chemical structure Triglycerides are tri-esters consisting of a glycerol bound to three fatty acid molecules. Alcohols have a hydroxyl (HO–) group. Organic acids have a carboxyl (–COOH) group. Alcohols and organic a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fledge
Fledging is the stage in a flying animal's life between hatching or birth and becoming capable of flight. This term is most frequently applied to birds, but is also used for bats. For altricial birds, those that spend more time in vulnerable condition in the nest, the nestling and fledging stage can be the same. For precocial birds, those that develop and leave the nest quickly, a short nestling stage precedes a longer fledging stage. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling. People often want to help fledglings, as they appear vulnerable, but it is best to leave them alone. The USA National Phenology Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (suc ...

Barnacle
A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmobile) and most are suspension feeders, but those in infraclass Rhizocephala are highly specialized parasites on crustaceans. They have four nektonic (active swimming) larval stages. Around 1,000 barnacle species are currently known. The name is Latin, meaning "curl-footed". The study of barnacles is called cirripedology. Description Barnacles are encrusters, attaching themselves temporarily to a hard substrate or a symbiont such as a whale (whale barnacles), a sea snake (''Platylepas ophiophila''), or another crustacean, like a crab or a lobster (Rhizocephala). The most common among them, "acorn barnacles" (Sessilia), are sessile where they grow their shells directly onto the substrate. Pedunculat ...

Krill
Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name "krill" comes from the Norwegian word ', meaning "small fry of fish", which is also often attributed to species of fish. Krill are considered an important trophic level connection – near the bottom of the food chain. They feed on phytoplankton and (to a lesser extent) zooplankton, yet also are the main source of food for many larger animals. In the Southern Ocean, one species, the Antarctic krill, ''Euphausia superba'', makes up an estimated biomass of around 379,000,000 tonnes, making it among the species with the largest total biomass. Over half of this biomass is eaten by whales, seals, penguins, seabirds, squid, and fish each year. Most krill species display large daily vertical migrations, thus providing food for predators near the surface at night and in deeper waters during the day. Krill are fished commercially in the Southern Ocean and in the waters around Ja ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cephalopod
A cephalopod is any member of the molluscan class Cephalopoda ( Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by '' Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ide ...

Mandible
In anatomy, the mandible, lower jaw or jawbone is the largest, strongest and lowest bone in the human facial skeleton. It forms the lower jaw and holds the lower teeth in place. The mandible sits beneath the maxilla. It is the only movable bone of the skull (discounting the ossicles of the middle ear). It is connected to the temporal bones by the temporomandibular joints. The bone is formed in the fetus from a fusion of the left and right mandibular prominences, and the point where these sides join, the mandibular symphysis, is still visible as a faint ridge in the midline. Like other symphyses in the body, this is a midline articulation where the bones are joined by fibrocartilage, but this articulation fuses together in early childhood.Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 59 The word "mandible" derives from the Latin word ''mandibula'', "jawbone" (literally "one used for chewing"), from '' mandere'' "to chew" and ''-bula'' (ins ...

James Clements
James Franklin "Jim" Clements (October 31, 1927 – June 9, 2005) was an American ornithologist, author and businessman. He was born in New York, United States. He married Mary Norton and they had two sons. His second marriage, which lasted 14 years, was to Christina. He married a third time, to Karen. He received his PhD from California Western University in 1975. His thesis became the first edition of his ''Birds of the World, A Check List'' (now in its sixth edition). Clements was mostly finished with the sixth edition at the time of his death, and responsibility for the series was taken up by the Cornell Laboratory of Ornithology (Cornell Lab) by arrangement with Clements's widow, Karen. The Cornell Lab finished the sixth edition, maintains corrections and updates for it, and plans to publish future editions. A bird, the Iquitos gnatcatcher, ''Polioptila clementsi'', is named after him. He died at Tri-City Hospital, Oceanside, California of complications associated wit ...

Agreement On The Conservation Of Albatrosses And Petrels
The Agreement on the Conservation of Albatrosses and Petrels (ACAP) is a legally binding international agreement signed in 2001 and entered into force on 1 February 2004 when South Africa ratified as the fifth Party to the Agreement. It was created in order to halt the drastic decline of seabird populations in the Southern Hemisphere, particularly of albatrosses and petrels. Albatrosses and petrels are threatened by introduced species on their breeding islands, pollution, and by being taken as bycatch by longline fisheries, as well as by trawl and gillnet fisheries. The Agreement requires that measures be taken by signatory governments to reduce bycatch; protect breeding colonies; and control and remove introduced species from breeding sites, especially on islands. Currently, ACAP protects all the world's albatross species, seven Southern Hemisphere petrel species and two shearwater species. The ongoing work of the Agreement reflects an increasing international commitment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
