Werner Ladiges
Werner Ladiges (August 15, 1910- November 13, 1984) was a German zoologist. Life He studied zoology in Innsbruck and Hamburg, where he received his doctorate in 1934. In the same year, his book ''Tropische Fische'' was published in the field of aquaristics, as well as numerous articles in relevant specialist journals. His main activity was as a scientific ichthyologist at the Hamburg Zoological Museum. Ladiges managed to make a name for himself with his influential specialist book ''Der Fisch in der Landschaft''. He is also known to aquarists for the Celebes rainbowfish (''Telmatherina ladigesi'', now ''Marosatherina ladigesi''), which he discovered in 1935 and which was named after him, and for the peaceful betta ''Betta imbellis'', which he described in 1975. For several years, Ladiges was editor of the popular aquaristic magazine ''TI – Tatsachen und Informationen aus der Aquaristik'', which was published by the accessories manufacturer Tetra in Melle, Germany.

Peruvian Amazon
Peruvian Amazonia (), informally known locally as the Peruvian jungle () or just the jungle (), is the area of the Amazon rainforest in Peru, east of the Andes and Peru's borders with Ecuador, Colombia, Brazil, and Bolivia. Peru has the second-largest portion of the Amazon rainforest after the Brazilian Amazon. Extension Most Peruvian territory is covered by dense forests on the east side of the Andes, yet only 5% of Peruvians live in this area. More than 60% of Peruvian territory is covered by the Amazon rainforest, more than in any other country.

Holopristis
The genus ''Holopristis'' was first erected by Carl H. Eigenmann in 1903, where it was noted to be related to ''Hemigrammus'' and distinguished by its dentition. The chosen name was created from (hólos) "entire" and (prístēs) meaning sawyer, the profession (one who saws), not a surname and alludes to the teeth of the new type being present all along the jaw. The name was then relegated to a synonym of ''Hemigrammus'' and was only revalidated in 2024, though this new system has yet to find wide acceptance. Species There are nine valid species: * '' Holopristis aguaruna'' F. C. T. Lima, Corrêa & Ota, 2016 * '' Holopristis falsa'' Meinken, 1958 * '' Holopristis guyanensis'' Géry, 1959 * '' Holopristis haraldi'' Géry, 1961 * '' Holopristis luelingi'' Géry, 1964 * '' Holopristis neptunus'' Zarske & Géry, 2002 * '' Holopristis ocellifer'' (Steindachner Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian zoologist, ichthyol ...

Freshwater Fish Of Colombia
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but 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. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always pot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Werner Ladiges
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1938
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
