Albert William Herre
Albert William Christian Theodore Herre (September 16, 1868 – January 16, 1962) was an American ichthyologist and lichenologist. Herre was born in 1868 in Toledo, Ohio. He was an alumnus of Stanford University, where he received a Bachelor of Science degree in botany in 1903. Herre also received a master's degree and a Ph.D. from Stanford, both in ichthyology. He died in Santa Cruz, California in 1962. Work in the Philippines Albert W. Herre was perhaps best known for his Taxonomy (biology), taxonomic work in the Philippines, where he was the Chief of Fisheries of the Bureau of Fisheries and Aquatic Resources, Bureau of Science in Manila from 1919 to 1928. While in the Bureau of Science of the Insular Government of the Philippine Islands (which were administered by the United States at the time), Herre was responsible for discovering and describing many new species of fish. Legacy Herre is commemorated in the scientific name of a species of gecko, ''Lepidodactylus herrei'', wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Net Casting
A casting net, also called a throw net, is a Fishing net, net used for fishing. It is a circular Fishing net, net with small Fishing sinker, weights distributed around its edge. The net is Casting (fishing), cast or thrown by hand in such a manner that it spreads out while it's in the air before it sinks into the water. This Fishing techniques, technique is called net casting or net throwing. Fish are caught as the net is hauled back in.Dunbar This simple device is particularly effective for catching small Bait fish, bait or forage fish, and has been in use, with various modifications, for thousands of years. __TOC__ Construction and technique Contemporary cast nets have a radius which ranges from 4 to 12 feet (1.2 to 3.6 metres). Only strong people can lift the larger nets once they are filled with fish. Standard nets for recreational fishing have a four-foot hoop. Weights are usually distributed around the edge at about one pound per foot (1.5 kilograms per metre). Attache ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1927
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Fauna Of Palawan
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of The Philippines
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of The Philippines
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranea (geography), subterranean subterranean river, rivers and underground lake, lakes. Fresh water is the Water resources, water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Visayan
Visayans (Visayan: ''mga Bisaya''; ) or Visayan people are a Philippine ethnolinguistic group or metaethnicity native to the Visayas, the southernmost islands of Luzon and a significant portion of Mindanao. When taken as a single ethnic group, they are both the most numerous in the entire country at around 33.5 million, as well as the most geographically widespread. The Visayans broadly share a maritime culture with strong Roman Catholic traditions integrated into a precolonial indigenous core through centuries of interaction and migration mainly across the Visayan, Sibuyan, Camotes, Bohol and Sulu seas. In more inland or otherwise secluded areas, ancient animistic-polytheistic beliefs and traditions either were reinterpreted within a Roman Catholic framework or syncretized with the new religion. Visayans are generally speakers of one or more of the Bisayan languages, the most widely spoken being Cebuano, followed by Hiligaynon (Ilonggo) and Waray-Waray. Terminology '' Ka ...

Expatriate
An expatriate (often shortened to expat) is a person who resides outside their native country. In common usage, the term often refers to educated professionals, skilled workers, or artists taking positions outside their home country, either independently or sent abroad by their employers. However, the term 'expatriate' is also used for retirees and others who have chosen to live outside their native country. Historically, it has also referred to exiles. Expatriates are immigrants or emigrants who maintain cultural ties such as the language of their country of origin. Etymology The word ''expatriate'' comes from the Latin terms '' ex'' ("out of") and ''patria'' ("native country, fatherland"). Semantics Dictionary definitions for the current meaning of the word include: :Expatriate: :* 'A person who lives outside their native country' (Oxford), or :* 'living in a foreign land' (Webster's). These definitions contrast with those of other words with a similar meaning, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Tilapia has been the fourth-most consumed fish in the United States since 2002. The popularity of tilapia came about due to its low price, easy preparation, and ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
