Masatierra Petrel
Masatierra petrel (''Pterodroma defilippiana'') or De Filippi's petrel, is a species of seabird in the family Procellariidae. It is endemic to Chile where it nests in the Juan Fernández Islands (including Masatierra) and Desventuradas Islands. Its natural habitats are open seas and rocky shores. Etymology The petrel was first described by Enrico Hillyer Giglioli in 1869 and named in honour of the Italian zoologist Professor Filippo de Filippi. Both these naturalists took part in an Italian government-sponsored scientific voyage to circumnavigate the world in 1866. The vessel returned successfully to Naples in 1868 but de Filippi died in Hong Kong from dysentery during the previous year. Giglioli took over the scientific work of the expedition after the professor's death. Description Masatierra petrel grows to a length of about . Its cap and mask are dark grey while its forehead is white. It has dark grey plumage on its upperparts with a distinctive "M" mark, a paler grey parti ...

Enrico Hillyer Giglioli
Enrico Hillyer Giglioli (13 June 1845 – 16 December 1909) was an 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 dorsal fin ...

Upwelling
Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water from deep water towards the ocean surface. It replaces the warmer and usually nutrient-depleted surface water. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers such as phytoplankton. The biomass of phytoplankton and the presence of cool water in those regions allow upwelling zones to be identified by cool sea surface temperatures (SST) and high concentrations of chlorophyll-a. The increased availability of nutrients in upwelling regions results in high levels of primary production and thus fishery production. Approximately 25% of the total global marine fish catches come from five upwellings, which occupy only 5% of the total ocean area.Jennings, S., Kaiser, M.J., Reynolds, J.D. (2001) "Marine Fisheries Ecology." Oxford: Blackwell Science Ltd. Upwellings that are driven by coastal currents or diverging ope ...

Coati
Coatis, also known as coatimundis (), are members of the family Procyonidae in the genera ''Nasua'' and ''Nasuella''. They are diurnal mammals native to South America, Central America, Mexico, and the southwestern United States. The name "coatimundi" comes from the Tupian languages of Brazil, where it means "lone coati". Locally in Belize, the coati is known as "quash". Physical characteristics Adult coatis measure from head to the base of the tail, which can be as long as their bodies. Coatis are about tall at the shoulder and weigh between , about the size of a large house cat. Males can become almost twice as large as females and have large, sharp canine teeth. The measurements above relate to the white-nosed and South America coatis. The two mountain coatis are smaller. All coatis share a slender head with an elongated, flexible, slightly upward-turned nose, small ears, dark feet, and a long, non- prehensile tail used for balance and signaling. Ring-tailed coatis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are 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, 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 taxon is Vulnerable when it is not critically endangered or Endangered but is fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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. According to IUCN the formally stated goals of the Red List are to provide scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Clara Island
Santa Clara Island ( es, Isla Santa Clara) is a tiny, uninhabited island in the Pacific Ocean, off the coast of Robinson Crusoe Island in a group of islands known as the Juan Fernández Islands. The island is of volcanic origin and is approximately long and wide. The island group is politically part of the South American country Chile, and is administratively assigned to the Region of Valparaíso. Geography Santa Clara is the smallest island of the Juan Fernandez Islands and has an area of about . It is surrounded on the south side by a reef. This volcanic islet is related to a group of three islands. Located southwest of Robinson Crusoe Island, it has a mainly flat surface, with a maximum altitude of at Johow Hill. Based on its geomorphological characteristics and the composition of its lavas, it is postulated to be the earliest volcanic center which led to the emergence of Robinson Crusoe Island, and is, therefore, of greater antiquity - 5.8 million years (as compared to 3.8 ...

Colony (biology)
In biology, a colony is composed of two or more conspecific individuals living in close association with, or connected to, one another. This association is usually for mutual benefit such as stronger defense or the ability to attack bigger prey. Colonies can form in various shapes and ways depending on the organism involved. For instance, the bacterial colony is a cluster of identical cells (clones). These colonies often form and grow on the surface of (or within) a solid medium, usually derived from a single parent cell. Colonies, in the context of development, may be composed of two or more unitary (or solitary) organisms or be modular organisms. Unitary organisms have determinate development (set life stages) from zygote to adult form and individuals or groups of individuals (colonies) are visually distinct. Modular organisms have indeterminate growth forms (life stages not set) through repeated iteration of genetically identical modules (or individuals), and it can be diffi ...
