Eduard Heinrich Graeffe
Eduard Heinrich Graeffe or Gräffe (27 December 1833, Zurich – 23 April 1916 Ljubljana) was a Swiss zoologist and naturalist. As an entomologist, he specialised in Hymenoptera, Diptera and Hemiptera. From around 1860, Graeffe was in the employ of Johann Cesar VI. Godeffroy, a wealthy shipping magnate from Hamburg. Graeffe was hired in order to organize Godeffroy's natural history collection as a scientific museum, the "Museum Godeffroy".Collectors Index Herbarium Lichen herbaria From 1862 to 1873, he was based in , conducting scientific research and collecting specimens from throughout the South Pacific.

Trieste
Trieste ( , ; sl, Trst ; german: Triest ) is a city and seaport in northeastern Italy. It is the capital city, and largest city, of the autonomous region of Friuli Venezia Giulia, one of two autonomous regions which are not subdivided into provinces. Trieste is located at the head of the Gulf of Trieste, on a narrow strip of Italian territory lying between the Adriatic Sea and Slovenia; Slovenia lies approximately east and southeast of the city, while Croatia is about to the south of the city. The city has a long coastline and is surrounded by grassland, forest, and karstic areas. The city has a subtropical climate, unusual in relation to its relatively high latitude, due to marine breezes. In 2022, it had a population of about 204,302. Capital of the autonomous region of Friuli Venezia Giulia and previously capital of the Province of Trieste, until its abolition on 1 October 2017. Trieste belonged to the Habsburg monarchy from 1382 until 1918. In the 19th century the mon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caroline Islands
The Caroline Islands (or the Carolines) are a widely scattered archipelago of tiny islands in the western Pacific Ocean, to the north of New Guinea. Politically, they are divided between the Federated States of Micronesia (FSM) in the central and eastern parts of the group, and Palau at the extreme western end. Historically, this area was also called ''Nuevas Filipinas'' or New Philippines, because they were part of the Spanish East Indies and were governed from Manila in the Philippines. The Carolines are scattered across a distance of approximately 3,540 kilometers (2,200 miles), from the westernmost island, Tobi (island), Tobi, in Palau, to the easternmost island, Kosrae, a Administrative divisions of the Federated States of Micronesia, state of the FSM. Description The group consists of about 500 small coral islands, east of the Philippines, in the Pacific Ocean. The distance from Yap (one of the larger Caroline islands) to Manila is .

Coelenterata
Coelenterata is a term encompassing the animal phyla Cnidaria (coral animals, true jellies, sea anemones, sea pens, and their relatives) and Ctenophora (comb jellies). The name comes , referring to the hollow body cavity common to these two phyla. They have very simple tissue organization, with only two layers of cells (ectoderm and endoderm), and radial symmetry. Some examples are corals, which are typically colonial, and hydrae, jellyfish, and sea anemones, which are solitary. Coelenterata lack a specialized circulatory system relying instead on diffusion across the tissue layers. Characteristics All coelenterates are aquatic, mostly marine, animals. The body form is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the , surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey. These tentacles are surrounded by a spacious cavity called the gastrovascular cavity, or coelen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Albert Grunow
Albert Grunow (3 November 1826, Berlin – 17 March 1914, Berndorf, Lower Austria) was a German-Austrian chemist and phycologist. He specialized in the study of diatoms. From 1851 he worked as a chemist in a metal works factory in Berndorf. In 1857-59 he participated in the Austrian " Novara Expedition", and was tasked with analysis of its algal collections. Also, he served as a collector, preparator and determiner of specimens towards the development of Gottlob Ludwig Rabenhorst's diatom exsiccatae. In 1901 he donated his collection of extant and fossil diatoms to the Natural History Museum of Vienna. He was a corresponding member of the ''Geologischen Reichsanstalt''.

Viti Levu
Viti Levu (pronounced ) is the largest island in the Republic of Fiji. It is the site of the nation's capital, Suva, and home to a large majority of Fiji's population. Geology Fiji lies in a tectonically complex area between the Australian Plate and the Pacific Plate. The Fiji Platform lies in a zone bordered by active extension fault lines, around which most of the shallow earthquakes in the area have been centred. These fault lines are: the Fiji Fracture Zone (FFZ) to the north; the 176° Extension Zone (176°E EZ) to the west; and the Hunter Fracture Zone (HFZ) and Lau Ridge to the east. The oldest rocks on the island are those formed during the Eocene and Lower Miocene epochs that belong to the Wainimala group. The lower portion of the group is made up of volcanic flows and volcanoclastics, which grade from basalt to trachyte and rhyolite. Geographically, this group is found south of Nadi, including on the peaks of Koromba (at 3528 feet high) and Natambumgguto (at 1242 ...

Freshwater Aquarium
A freshwater aquarium is a receptacle that holds one or more freshwater aquatic organisms for decorative, pet-keeping, or research purposes. Modern aquariums are most often made from transparent glass or acrylic glass. Typical inhabitants include fish, plants, amphibians, and invertebrates, such as snails and crustaceans. Freshwater fish may be either coldwater or tropical species. Although freshwater aquariums can be set up as community tanks, coldwater and tropical fish are generally not mixed due to incompatibilities in temperature requirements. Coldwater aquariums house goldfish and other species that do not require a heating apparatus. Warmer temperatures would actually increase their metabolism and shorten their lifespan.Johnson, E. L., & Hess, R. E. (2006). ''Fancy goldfish: A complete guide to care and collecting'', Weatherhill: Shambala Publications, Inc. For a tropical fish tank, maintaining a warm environmental temperature ranging between 75 and 80 °F (24 to 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radiata
Radiata or Radiates is a historical taxonomic rank that was used to classify animals with radially symmetric body plans. The term Radiata is no longer accepted, as it united several different groupings of animals that do not form a monophyletic group under current views of animal phylogeny. The similarities once offered in justification of the taxon, such as radial symmetry, are now taken to be the result of either incorrect evaluations by early researchers or convergent evolution, rather than an indication of a common ancestor. Because of this, the term is used mostly in a historical context. In the early 19th century, Georges Cuvier united Ctenophora and Cnidaria in the Radiata (''Zoophytes''). Thomas Cavalier-Smith, in 1983, redefined Radiata as a subkingdom consisting of Myxozoa, Placozoa, Cnidaria and Ctenophora. Lynn Margulis and K. V. Schwartz later redefined Radiata in their '' Five Kingdom'' classification, this time including only Cnidaria and Ctenophora. This definiti ...
