Craveri's Murrelet
Craveri's murrelet (''Synthliboramphus craveri'') is a small seabird which breeds on offshore islands in both the Pacific Ocean and the Gulf of California off the Baja peninsula of Mexico. It also wanders fairly regularly as far as central California in the US, primarily during post-breeding dispersal. It is threatened by predators introduced to its breeding colonies, by oil spills, and by tanker traffic. Increasing tourism development and commercial fishing fleets also further threaten the species. With an estimated population of 6,000-10,000 breeding pairs, its population is listed as vulnerable. Description and range The Craveri's murrelet is a small black and white auk with a small head and thin sharp bill. It resembles the closely related Scripps's murrelet, with which it shares the distinction of being the most southerly living of all the auk species. The Craveri's murrelet has a partial neck collar (Scripps's has none), and dusky underwings (Scripps's has white un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tommaso Salvadori
Count Adelardo Tommaso Salvadori Paleotti (30 September 1835 – 9 October 1923) was an Italian zoologist and ornithologist. Biography Salvadori was born in Porto San Giorgio, son of Count Luigi Salvadori and Ethelyn Welby, who was English. His brother Giorgio married their cousin Adele Emiliani (daughter of Giacomo Emiliani and Casson Adelaide Welby) and had five children (Charlie, Robbie, Minnie, Nellie and Guglielmo "Willie").

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Birds Of Mexico
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthliboramphus
''Synthliboramphus'' is a small genus of seabirds in the auk family from the North Pacific. The genus name ''Synthliboramphus'' is from Ancient Greek ''sunthlibo'', "to compress", and ''rhamphos'', "bill". The English name "Murrelet" is a diminutive of "murre", a word of uncertain origins, but which may imitate the call of the common guillemot. Taxonomy The genus ''Synthliboramphus'' was introduced in 1837 by the German born naturalist Johann Friedrich von Brandt. The type genus was subsequently designated by George Robert Gray as the ancient murrelet. The genus name combines Ancient Greek ''sunthlibō'' meaning "to compress" with ''rhamphos'' meaning "bill". The genus contains five species: The first two species were formally considered conspecific, and are sometimes separated in the genus ''Endomychura''. Fossil remains of two prehistoric species are known: an undescribed ''Synthliboramphus'' sp. from the Late Miocene or Early Pliocene (c. 5 mya) of Cedros Island, Mexi ...

Auks
An auk or alcid is a bird of the family Alcidae in the order Charadriiformes. The alcid family includes the murres, guillemots, auklets, puffins, and murrelets. The word "auk" is derived from Icelandic ''álka'', from Old Norse ''alka'' (auk), from Proto-Germanic *''alkǭ'' (sea-bird, auk). The family contains 25 extant or recently extinct species that are divided into 11 genera. Apart from the extinct great auk, all auks can fly, and are excellent swimmers (appearing to "fly") and divers, but their walking appears clumsy. Several species have different English names in Europe and North America. The two species known as murres in North America are called guillemots in Europe, and the species called little auk in Europe is referred to as dovekie in North America. Description Auks are superficially similar to penguins, having black-and-white colours, upright posture, and some of their habits. Nevertheless, they are not closely related to penguins, but rather are believed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turin Museum Of Natural History
The Turin Museum of Natural History (Italian: ''Museo Regionale di Scienze Naturali di Torino'' or MRSN) was established in 1978 to house the natural history collections of the University of Turin and other collections of natural history, originated from specific research campaigns and donations. It is located at 36 Via Giolitti, Turin, in a 17th-century building which used to be the hospital of San Giovanni Battista, build by Amedeo di Castellamonte. The museum has departments (sezioni) of zoology, entomology, botany, minerals, geology and paleontology. It also has a specialist library and an exhibition centre. People Naturalists associated with the collections include: *Franco Andrea Bonelli *Maximilian Spinola *Luigi Bellardi Luigi Bellardi (18 May 1818 – 17 September 1889) was an Italian malacologist and entomologist who specialised in Diptera. Bellardi was born in Genoa and died in Turin. His collection is in the Turin Museum of Natural History In 1872, then a Pro .. ...

Ettore Craveri
Federico Craveri (Turin, 1815 – Bra, 1890) was an Italian explorer, ethnographer, geologist, meteorologist and naturalist noted for his studies in Mexico. Biography Federico Craveri studied chemistry and meteorology at the University of Turin. In 1840 he moved to Mexico, which had recently gained independence from Spain. From 1840 until 1859 he taught chemistry at the National Museum in Mexico City. In Mexico, he obtained a graduation in Chemistry and Pharmacy. In 1847 he was joined in Mexico for two years by his brother Ettore, who shared similar interest in nature. Federico Craveri explored this country for a few years (1855–1857) to study its geology, with particular regard to the Trans-Mexican Volcanic Belt. In Mexico as well in the United States Federico Craveri collected specimens of many animals and plants. These collections were placed, on his return to Italy, in the family home of Bra. For thirty years he took care of the classification of the material brought back ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Island Restoration
The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals. Their ecosystems are also very vulnerable to human disturbance and particularly to introduced species, due to their small size. Island groups such as New Zealand and Hawaii have undergone substantial extinctions and losses of habitat. Since the 1950s several organisations and government agencies around the world have worked to restore islands to their original states; New Zealand has used them to hold natural populations of species that would otherwise be unable to survive in the wild. The principal components of island restoration are the removal of introduced species and the reintroduction of native species. Islands, endemism and extinction Isolated islands have been know ...

Feral Cat
A feral cat or a stray cat is an unowned domestic cat (''Felis catus'') that lives outdoors and avoids human contact: it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens of generations and become an aggressive local apex predator in urban, savannah and bushland environments. Some feral cats may become more comfortable with people who regularly feed them, but even with long-term attempts at socialization, they usually remain aloof and are most active after dusk. Feral cats are devastating to wildlife, and conservation biologists consider them to be one of the worst invasive species on Earth. Attempts to control feral cat populations are widespread but generally of greatest impact within purpose-fenced reserves. Some animal rights groups advocate trap-neuter-return programs to prevent the feral cats from continuing to breed. Scientific evidence has demonstrated that TNR is not effective at controlling f ...

Mice
A mouse ( : mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (''Mus musculus''). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size. Generally, when a muroid rodent is discovered, its common name includes the term ''mouse'' if it is smaller, or ''rat'' if it is larger. The common terms ''rat'' and ''mouse'' are not taxonomically specific. Typical mice are classified in the genus '' Mus'', but the term ''mouse'' is not confined to members of ''Mus'' and can also apply to species from other genera such as the deer mouse, ''Peromyscus''. Domestic mice sold as pets often differ substantially in size from the common house mouse. This is attributable to breeding a ...

Precocial
In biology, altricial species are those in which the young are underdeveloped at the time of birth, but with the aid of their parents mature after birth. Precocial species are those in which the young are relatively mature and mobile from the moment of birth or hatching. Precocial species are normally nidifugous, meaning that they leave the nest shortly after birth or hatching. These categories form a continuum, without distinct gaps between them. Altriciality Etymology The word is derived from the Latin root ''alere'', meaning "to nurse, to rear, or to nourish" and indicates the need for young to be fed and taken care of for a long duration. By contrast, species whose young are immediately or quickly mobile are called ''precocial''. Precociality Etymology The word "precocial" is derived from the same root as ''precocious'', implying early maturity in both cases. Superprecociality Extremely precocial species are called "superprecocial". Examples are the megapode birds, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
