Gustav Hartlaub
Karel Johan Gustav Hartlaub (8 November 1814 – 29 November 1900) was a German physician and ornithologist. Hartlaub was born in Bremen, and studied at Bonn and Berlin before graduating in medicine at Göttingen. In 1840, he began to study and collect exotic birds, which he donated to the Bremen Natural History Museum. He described some of these species for the first time. In 1852, he set up a new journal with Jean Cabanis, the ''Journal für Ornithologie''. He wrote with Otto Finsch, ''Beitrag zur Fauna Centralpolynesiens: Ornithologie der Viti-, Samoa und Tonga- Inseln''. Halle, H. Schmidt. This 1867 work which has handcoloured lithographs was based on bird specimens collected by Eduard Heinrich Graeffe for Museum Godeffroy. A number of birds were named for him, including Hartlaub's Bustard, Hartlaub's Turaco, Hartlaub's Duck, and Hartlaub's Gull Hartlaub's gull (''Chroicocephalus hartlaubii''), also known as the king gull, it is a small gull. It was formerly sometimes cons ... [...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 ...

Fauna Of The Kerguelen Islands
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 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chionis
The sheathbills are a family (biology), family of birds, Chionidae. Classified in the wader order Charadriiformes, the family consists of one genus, ''Chionis'' with two species. They breed on subantarctic islands and the Antarctic Peninsula, and the snowy sheathbill migrates to the Falkland Islands and coastal southern South America in the southern winter; they are the only bird family endemism in birds, endemic as breeders to the Antarctic region. They are also the only Antarctic birds without webbed feet. Taxonomy The genus ''Chionis'' was introduced in 1788 by the German naturalist Johann Reinhold Forster. The type species is the snowy sheathbill. The genus name is from the Ancient Greek ''khiōn'' meaning snow. Description They have white Feather, plumage including a thick layer of down, with only the face and leg colours distinguishing the two species. They look plump and dove-like, but are believed to be similar to the ancestors of the modern gulls and terns. There is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Photographic Index Of Australian Wildlife
The National Photographic Index of Australian Wildlife was founded as a project of the Australian Museum on 3 June 1969 (as the National Photographic Index of Australian Birds) to compile a comprehensive collection of photographs of Australian bird species. The founder, Donald Trounson, served as the project’s chief executive officer until 1981, when he was succeeded by Ronald Strahan. It was established in association with the National Library of Australia under the direction of a trust chaired by Sir Percy Spender and was the first systematic attempt to compile a comprehensive photographic record of the birds of any country. In 1977 it was expanded to include mammals and, in 1984, reptiles and frogs, with the aim of progressively including other animal groups to become the most comprehensive possible archive of photographs of Australian wildlife and to provide an expanding service to the public, to photographers and to biological science. In November 1980 the Index was inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Toxic Waste
Toxic waste is any unwanted material in all forms that can cause harm (e.g. by being inhaled, swallowed, or absorbed through the skin). Mostly generated by industry, consumer products like televisions, computers, and phones contain toxic chemicals that can pollute the air and contaminate soil and water. Disposing of such waste is a major public health issue. Classifying toxic materials Toxic materials are poisonous byproducts as a result of industries such as manufacturing, farming, construction, automotive, laboratories, and hospitals which may contain heavy metals, radiation, dangerous pathogens, or other toxins. Toxic waste has become more abundant since the industrial revolution, causing serious global issues. Disposing of such waste has become even more critical with the addition of numerous technological advances containing toxic chemical components. Products such as cellular telephones, computers, televisions, and solar panels contain toxic chemicals that can harm th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Faeces
Feces ( or faeces), known colloquially and in slang as poo and poop, are the solid or semi-solid remains of food that was not digested in the small intestine, and has been broken down by bacteria in the large intestine. Feces contain a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and dead epithelial cells from the lining of the gut. Feces are discharged through the anus or cloaca during defecation. Feces can be used as fertilizer or soil conditioner in agriculture. They can also be burned as fuel or dried and used for construction. Some medicinal uses have been found. In the case of human feces, fecal transplants or fecal bacteriotherapy are in use. Urine and feces together are called excreta. Skatole is the principal compound responsible for the unpleasant smell of feces. Characteristics The distinctive odor of feces is due to skatole, and thiols (sulfur-containing compounds), as well as amines and carboxylic acids. Skatole ...

Carrion
Carrion () is the decaying flesh of dead animals, including human flesh. Overview Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eaters (or scavengers) include crows, vultures, condors, hawks, eagles, hyenas, Virginia opossum, Tasmanian devils, coyotes and Komodo dragons. Many invertebrates, such as the carrion and burying beetles, as well as maggots of calliphorid flies (such as one of the most important species in '' Calliphora vomitoria'') and flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains. Carrion begins to decay at the moment of the animal's death, and it will increasingly attract insects and breed bacteria. Not long after the animal has died, its body will begin to exude a foul odor caused by the presence of bacteria and the emission of cadaverine and putrescine. Some plants and fungi smell like decomposing carrion and attract insects that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
