Yelkouan Shearwater
upright=0.8, Egg of the yelkouan shearwater The yelkouan shearwater, Levantine shearwater or Mediterranean shearwater (''Puffinus yelkouan'') is a medium-sized shearwater in the seabird family Procellariidae. It was formerly treated as a subspecies of the Manx shearwater (''Puffinus puffinus''). Taxonomy The yelkouan shearwater was formally described in 1827 by the Italian naturalist Giuseppe Acerbi from specimens collected in the Bosphorus, Turkey. He placed the shearwater in the genus ''Procellaria'' and coined the binomial name ''Procellaria yelkouan''. The yelkouan shearwater is now placed in the genus ''Puffinus'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The genus name ''Puffinus'' is Neo-Latin based on the English "puffin". The specific ''yelkouan'' is the Turkish word "wind chaser" for a shearwater. The yelkouan shearwater is considered to be monotypic: no subspecies are recognised. It was formerly considered a subspecies of the Manx shea ...

Giuseppe Acerbi
Giuseppe Acerbi (May 3, 1773August 25, 1846) was an Italian naturalist, explorer and composer. Biography Giuseppe Acerbi was born on May 3, 1773, in Castel Goffredo, in Lombardy. He was an Italian naturalist, explorer and composer. In 1798, Acerbi traveled to Lapland, publishing his experiences in ''Travels through Sweden, Finland and Lapland to the North Cape in the years 1798 and 1799'' (1802). Some of his works can be found in the New York Society Library in New York, New York. He also written other works along with compositions that became popular. During his travels, he collected some Finnish folk melodies and religious songs, one of which he used in a Clarinet Concerto. This was the first Finnish melody to be used in serious music. In 1836, Acerbi retired from his travels and career. He returned to his hometown Castel Goffredo. He began to organize and administer his notes and collections from his travels. He never completed the task; Giuseppe Acerbi died in his hometo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balearic Shearwater
The Balearic shearwater (''Puffinus mauretanicus'') is a medium-sized shearwater in the seabird family ''Procellariidae''. ''Puffinus'' is a Neo-Latin loanword based on the English "puffin" and its variants, that referred to the cured carcass of the fat nestling of the Manx shearwater, a former delicacy. The specific ''mauretanicus'' refers to Mauretania, an old name for an area of North Africa roughly corresponding to Morocco and Algeria. The Balearic Shearwater is listed critically endangered by the IUCN and is one of Europe's most endangered seabirds. Taxonomy The Balearic shearwater was formerly described in 1921 by the English ornithologist Percy Lowe. He treated it as a subspecies of the Manx shearwater and coined the trinomial name ''Puffinus puffinus mauretanicus''. The Balearic shearwater was long regarded a subspecies of the Manx shearwater. Following an initial split, it was held to be a subspecies of the "Mediterranean shearwater" for nearly ten more years, unti ...

DNA Sequence
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence represents genetic information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from 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 () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Puffinus Nestori
''Puffinus nestori'' is an extinct seabird in the petrel family. Its fossil remains, dating from the late Pliocene to early Pleistocene, were found on the island of Ibiza of the Balearic archipelago in the western Mediterranean.

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Menorca
Menorca or Minorca (from , later ''Minorica'') is one of the Balearic Islands located in the Mediterranean Sea belonging to Spain. Its name derives from its size, contrasting it with nearby Mallorca. Its capital is Maó, situated on the island's eastern end, although Menorca is not a province and forms a political union with the other islands in the archipelago. Ciutadella de Menorca, Ciutadella and Maó are the main ports and largest towns. Menorca had a population of 102,477 at the Census of 1 January 2025, Its highest point, called El Toro (Minorca), El Toro (from Catalan "''turó''" meaning ''hill''), roughly in the middle of the island, is Above mean sea level, above sea level. History The island is known for its collection of European megalithic culture, megalithic stone monuments: naveta, ''navetes'', taula, ''taules'' and ''talaiots'', which indicate very early prehistoric human activity.

Lava Shearwater
The lava shearwater (''Puffinus olsoni''), or Olson's shearwater, was a species of shearwater that bred on Lanzarote and Fuerteventura in the Canary Islands. It is known from fossil remains, and was only described in 1990. It was intermediate in size between the Manx shearwater and the little shearwater. The remains of the species are particularly common in lava fields. The species is thought to have survived the arrival of the first settlers in the Canary Islands, and become extinct after the arrival of European settlers in the 15th century. It is suspected that the species became extinct due to hunting pressures and possibly the arrival of introduced species such as rat Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus ''Rattus''. Other rat genera include '' Neotoma'' (pack rats), '' Bandicota'' (bandicoo ...s.

Hole's Shearwater
The dune shearwater (''Puffinus holeae''), also known as the Canarian shearwater or Hole's shearwater, was a relatively large shearwater which bred in the Canary Islands archipelago of the North Atlantic Ocean. Fossils have also been found in the Figueira Brava cave archaeological site on the western coast of Portugal. The specific epithet honours Mrs Jean Hole, who collected fossil material of the species on the Jandia Peninsula of Fuerteventura. It was intermediate in size between the Manx and Cory's shearwaters. Its breeding colonies were in dune fields, in contrast to those of the smaller and sympatric lava shearwater which bred in lava fields. The species went extinct about 2000–3000 years ago, contemporaneously with the first human settlement of the islands by the Guanches The Guanche were the Indigenous peoples, indigenous inhabitants of the Spain, Spanish Canary Islands, located in the Atlantic Ocean some to the west of modern Morocco and the North Africa ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...
