Gerlof Fokko Mees
Gerlof Fokko Mees (16 June 1926 – 31 March 2013) was a Dutch ichthyologist, ornithologist and museum curator. During 1946 to 1949 he took part as a conscript in the military actions to reestablish rule in the Dutch East Indies. During that time he became interested in the avian family Zosteropidae, comprising the white-eyes. Mees was born at Bloemendaal in the Netherlands. He was introduced to natural history by his parents and was introduced to birds by his uncle Jan Verwey. He attended the University of Leiden where he studied biology, obtaining his doctorate in 1956 with a break in Java as part of the Dutch forces during the Indonesian war of independence. It was during his time in Java that he took a special interest in white-eyes (''Zosterops'') and also an introduction to George Junge. During 1953-54 he visited Trinidad and Tobago and collected bird specimens. He was an assistant at the department birds of the Rijksmuseum van Natuurlijke Historie in Leiden from May 1955 t ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Grunter
Grunters or tigerperches are ray-finned fishes in the family Terapontidae (also spelled Teraponidae, Theraponidae or Therapontidae). This family is part of the superfamily Percoidea of the order Perciformes. Characteristics The Terapontidae is a large family of small to medium-sized perciform fishes which occur in marine, brackish and fresh waters in the Indo-Pacific region. They are characterised by a single long-based dorsal fin which has a notch marking the boundary between the spiny and soft-rayed portions. They have small to moderate-sized scales, a continuous lateral line reaching the caudal fin, and most species lack teeth on the roof of the mouth. The marine species are found in inshore sea and brackish waters, some species are able to enter extremely saline and fresh waters. In Australia and New Guinea there are a number of species restricted to fresh water. Classification The following genera are classified within the family Terpontidae: * '' Amniataba'' Whitley ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Yamur
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

West Papua (region)
Western New Guinea, also known as Papua, Indonesian New Guinea, or Indonesian Papua, is the western half of the Melanesian island of New Guinea which is administered by Indonesia. Since the island is alternatively named as Papua, the region is also called West Papua ( id, Papua Barat). Lying to the west of Papua New Guinea and considered a part of the Australian continent, the territory is almost entirely in the Southern Hemisphere and includes the Schouten and Raja Ampat archipelagoes. The region is predominantly covered with ancient rainforest where numerous traditional tribes live such as the Dani of the Baliem Valley although a large proportion of the population live in or near coastal areas with the largest city being Jayapura. Within five years following its proclamation of independence in 1945, the Republic of Indonesia (for a time part of the United States of Indonesia) took over all the former territories of the Dutch East Indies except Western New Guinea, accord ...

Freshwater Fish Of Western New Guinea
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, subterranean rivers and lakes. Fresh water is the 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 insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...
