Carl Robert Osten-Sacken
Carl Robert Osten-Sacken or Carl-Robert Romanovich, Baron von der Osten-Sacken, Baron Osten Sacken (21 August 1828, – 20 May 1906) was a Russian diplomat and entomologist. He served as the Russian consul general in New York City during the American Civil War, living in the United States from 1856 to 1877. He worked on the taxonomy of flies in general and particularly of the family Tipulidae (crane flies). Early life Carl Robert Osten-Sacken was born on 21 August 1828 in St. Petersburg as the son of Baltic German Baron Reinhold Friedrich von der Osten-Sacken (1791-1864) and his wife, Elisabeth von Engelhardt (1805-1873). Biography He took an interest in insects at the age of eleven through the influence of Joseph N. Schatiloff, a Russian coleopterist. In 1849 he joined the Imperial Foreign Office and while still in Russia he published his first entomological papers, including an account of the species found in the suburbs of St. Petersburg. In 1856, he was sent to Was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Europaea
Fauna Europaea is a database of the scientific names and distribution of all living multicellular European land and fresh-water animals.

Synanthrope
A synanthrope (from the Greek σύν ''syn'', "together with" + ἄνθρωπος ''anthropos'', "man") is a member of a species of wild animal or plant that lives near, and benefits from, an association with human beings and the somewhat artificial habitats that people create around themselves (see anthropophilia). Such habitats include houses, gardens, farms, roadsides and rubbish dumps. The category of synanthrope includes many species regarded as pests or weeds. It does not, however, include domesticated animals such as cattle, honeybees, pets, poultry, silkworms, and working animals. Examples of synanthropes are various insect species ( lice, ants, silverfish, cockroaches, etc.), house sparrows, rock doves (pigeons), crows, various rodent species, Virginia opossums, raccoons, certain monkey species, coyotes, deer, urban ferals, passerines, and other urban wildlife. Plants include Pineapple Weed, Dandelion, Chicory, and Plantain. The brown rat is counted as one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kahiltna Glacier
Kahiltna Glacier is the longest glacier of the Alaska Range in the U.S. state of Alaska. It starts on the southwest slope of Denali near Kahiltna Pass (elevation ). Its main channel runs almost due south between Mount Foraker to the west and Mount Hunter to the east. The name was first reported as "Car-ilt-nu Glacier" by Alaska Range explorer Lt. J.S. Herron in 1902. An alternate name is Kagheltnu Li'a. Kahiltna Glacier is the longest glacier in the Alaska Range at in length. Forks The glacier has a few notable forks. The Northeast Fork lies just under, and to the south of, the large plateau which houses the camp on the standard West Buttress route of Denali. It also provides access to the less popular, but more technical, West Rib and Cassin Ridge routes. The East Fork is rarely visited, but provides access to the west side of the South Buttress of Denali. The mouth of the Southeast Fork is the site of the seasonal airstrip and base camp for Denali at approximately the 7,00 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west. The ...

Mount McKinley
Denali (; also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of above sea level. With a topographic prominence of and a topographic isolation of , Denali is the third most prominent and third most isolated peak on Earth, after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve. The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley; that name was the official name recognized by the federal government of the United States from 1917 until 2015. In August 2015, 40 years after Alaska had done so, the United States Department of the Interior announced the change of the official name of the mountain to Denali. In 1903, Jame ...

Nearctic
The Nearctic realm is one of the eight biogeographic realms constituting the Earth's land surface. The Nearctic realm covers most of North America, including Greenland, Central Florida, and the highlands of Mexico. The parts of North America that are not in the Nearctic realm are Eastern Mexico, Southern Florida, coastal Central Florida, Central America, and the Caribbean islands, which, together with South America, are part of the Neotropical realm. Major ecological regions The World Wildlife Fund (WWF) divides the Nearctic into four bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." Canadian Shield The Canadian Shield bioregion extends across the northern portion of the continent, from the Aleutian Islands to Newfoundland. It includes the Nearctic's Arctic Tundra and Boreal forest ecoregions. In terms of flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, ...

Indomalaya
The Indomalayan realm is one of the eight biogeographic realms. It extends across most of South and Southeast Asia and into the southern parts of East Asia. Also called the Oriental realm by biogeographers, Indomalaya spreads all over the Indian subcontinent and Southeast Asia to lowland southern China, and through Indonesia as far as Sumatra, Java, Bali, and Borneo, east of which lies the Wallace line, the realm boundary named after Alfred Russel Wallace which separates Indomalaya from Australasian realm, Australasia. Indomalaya also includes the Philippines, lowland Taiwan, and Japan's Ryukyu Islands. Most of Indomalaya was originally covered by forest, and includes tropical and subtropical moist broadleaf forests, with tropical and subtropical dry broadleaf forests predominant in much of India and parts of Southeast Asia. The tropical forests of Indomalaya are highly variable and diverse, with economically important trees, especially in the families Dipterocarpaceae and Faba ...
