Trindade Petrel
The Trindade petrel (''Pterodroma arminjoniana'') is a species of seabird and a member of the gadfly petrels. The bird is in size, with an wingspan. The petrel has various color morphs: dark and light, as well as intermediates between the two. Previously, two separate populations were considered conspecific, one occurring in the south Pacific, sometimes seen in Hawaii; the other occurring in the south Atlantic, nesting off Brazil, with regular sightings in the Gulf Stream off the southeastern United States. The little-known Pacific birds were then split and determined distinct as the Herald petrel, ''Pterodroma heraldica''. It uses oceanic islands and atolls, nesting on cliff ledges, ridges or rocky slopes. On some islands, nesting birds are threatened by feral cats and rats. Due to ongoing habitat loss and small breeding range, this species is evaluated as vulnerable on the IUCN Red List of Threatened Species The International Union for Conservation of Nature (IUCN) Red ...

Enrico Hillyer Giglioli
Enrico Hillyer Giglioli (13 June 1845 – 16 December 1909) was an Italians, Italian zoologist and anthropologist. Giglioli was born in London and first studied there. He obtained a degree in science at the University of Pisa in 1864 and started to teach zoology in Florence in 1869. Marine vertebrates, and invertebrates, were his academic interest but he was a noted amateur ornithologist and photographer. Giglioli was director of the Royal Zoological Museum in Florence, Italy. He wrote up the zoology of the voyage of the corvette on which he had taken over from Filippo de Filippi. Professor De Filippi died in Hong Kong in 1867. He was also involved in the activities of the Florence School of Anthropology and through this developed an interest in ethnography. In 1901, he was elected as a member of the American Philosophical Society. Whale sightings In 1870 he reported seeing a new species of whale (unofficially called Giglioli's Whale) off the coast of Chile long with two dor ...

Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1869
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species.

Nature Conservation Act Endangered Biota
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Birds Of Brazil
Brazil has one of the richest bird diversities in the world. The avifauna of Brazil include a total of 1858 confirmed species of which 238 are endemic. Five have been introduced by humans, 96 are rare or vagrants, and five are extinct or extirpated. An additional 14 species are hypothetical (see below). Brazil hosts about 60% of the bird species recorded for all of South America. These numbers are still increasing almost every year, due to new occurrences, new species being described, or splits of existing species. About 10% of the bird species found in Brazil are, nonetheless, threatened. In June 2013 a simultaneous discovery of fifteen bird species in Brazil was announced, the first such since 1871, when August von Pelzeln described forty new species. The birds were from the families Corvidae, Thamnophilidae, Dendrocolaptidae, Tyrannidae, and Polioptilidae. Eleven of the new species are endemics of Brazil and four also inhabit Peru and Bolivia.

Vittorio Arminjon
Vittorio Arminjon or Victor Arminjon (9 October 1830 – 4 February 1897) was an Italian admiral, explorer and writer. Arminjon was born in Chambéry to Senator Mathias Arminjon and Henriette Dupy. He joined the Royal Naval School in Genoa in 1842 and became an officer in 1847. He served on the Adriatic Sea (1848-1849) and resigned in 1860 to join the French Navy commanding the ''Zenobia'' and later the ''Asmodeus''. He was made a Knight in the Order of the Legion of Honor. He married Enrichetta Alli-Maccarani, daughter of Marquis Alli Maccarani in 1859. In 1861 he joined back with the Royal Italian Navy and served as a captain on a Frigate. In 1865 he commanded the frigate ''Regina'' from Naples to Montevideo and from there the steamship ''Magenta'' on a voyage around the world. The ship also carried the naturalists Prof. Enrico Hillyer Giglioli and Filippo de Filippi who collected and described various zoological specimens including the Trindade petrel which was named after Armin ...

IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

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 ...
