Charles Paul Alexander
Charles Paul Alexander (September 25, 1889, Gloversville, New York – December 3, 1981) was an American entomologist who specialized in the Tipulidae family of craneflies. Charles Paul Alexander was the son of Emil Alexander and Jane Alexander (née Parker). Emil (the father) immigrated to the United States in 1873 and changed his surname from Schlandensky to Alexander. Charles entered Cornell University in 1909, earning a Bachelor of Science in 1913 and a Ph.D. in 1918. Between 1917 and 1919, he was entomologist at the University of Kansas, then from 1919 to 1922, at the University of Illinois. He then became professor of entomology at Massachusetts Agricultural College The University of Massachusetts Amherst (UMass Amherst) is a Public university, public land-grant university, land-grant research university in Amherst, Massachusetts, United States.

The Great Basin Naturalist
''Western North American Naturalist'', formerly ''The Great Basin Naturalist'', is a peer-reviewed scientific journal focusing on biodiversity and conservation of western North America. The journal's geographic coverage includes "from northernmost Canada and Alaska to southern Mexico, and from the Mississippi River to the Pacific Ocean." Established in 1939, it is published by the Monte L. Bean Life Science Museum (Brigham Young University). The journal is published quarterly, with monographs published irregularly in ''Monographs of the Western North American Naturalist''. History Vasco M. Tanner founded the magazine after a term as editor at ''Proceedings'' magazine. His hope for the journal was to have a publication that covered a wide range of biology-related topics in addition to having a place to publish his own research. From 1939 through 1966, the journal limited the publication of their issues to once or twice a year due to World War II. Franklin Harris encouraged the jo ...

Crane Fly
A crane fly is any member of the dipteran superfamily Tipuloidea, which contains the living families Cylindrotomidae, Limoniidae, Pediciidae and Tipulidae, as well as several extinct families. "Winter crane flies", members of the family Trichoceridae, are sufficiently different from the typical crane flies of Tipuloidea to be excluded from the superfamily Tipuloidea, and are placed as their sister group within Tipulomorpha. Two other families of flies, the phantom crane flies ( Ptychopteridae) and primitive crane flies ( Tanyderidae), have similar common names due their similar appearance, but they are not closely related to true crane flies. The classification of crane flies has been varied in the past, with some or all of these families treated as subfamilies, but the following classification is currently accepted. Species counts are approximate, and vary over time. ; Infraorder Tipulomorpha : Superfamily Tipuloidea (Typical Crane Flies) :: Family Cylindrotomidae (Cy ...

Tipulidae
Tipulidae is a family of large Crane fly, crane flies in the order Diptera. There are more than 30 genera and 4,200 described species in Tipulidae, common and widespread throughout the world. A crane fly can be identified as a member of Tipulidae by its maxillary palps, which is the pair of appendages that hang down from the front of its head. If the fourth segment (the furthest from the body) of the maxillary palp is longer than the other three combined, then it is likely to be a member of Tipulidae. There are also usually 13 segments in the antennae of large crane flies, compared to 14 or 16 in the common Limoniidae, limoniid crane flies. The oldest fossils that can be assigned confidently to Tipulidae ''sensu stricto'' are those of the genus ''Tipunia,'' which date to the Late Jurassic. Genera These 39 genera belong to the family Tipulidae: * ''Acracantha'' Skuse, 1890 * ''Angarotipula'' Savchenko, 1961 * ''Austrotipula'' Alexander, 1920 * ''Brachypremna'' Osten Sacken, 1 ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Muldrow Glacier
Muldrow Glacier, also known as McKinley Glacier, is a large glacier in Denali National Park and Preserve in the U.S. state of Alaska. Native names for the glacier include, Henteel No' Loo' and Henteel No' Loot. The glacier originates from the Great Icefall of Harper Glacier on the eastern side of Denali. The glacier moves generally eastward, receiving Traleika Glacier and Brooks Glacier as tributaries, then turning northward to emerge from the Alaska Range as the source of the McKinley River. Muldrow Glacier was renamed by Alfred Hulse Brooks in 1902 in honor of U.S. Geological Survey topographer Robert Muldrow. In 2021, the glacier was noted to be growing in a surge that greatly exceeds the scant previous records of its status. In April that year scientists were documenting growth of the glacier at one hundred times its normal rate, advancing up to ninety feet a day during the prior few months.

Denali
Denali (), federally designated as Mount McKinley, is the highest mountain peak in North America, with a summit elevation of above sea level. It is the tallest mountain in the world from base to peak on land, measuring . On p. 20 of Helman (2005):"the base to peak rise of Mount McKinley is the largest of any mountain that lies entirely above sea level, some ". 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, who later became the 25th president; McKinley's name was the official na ...

Diptera Of North America
Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced mechanosensory organs known as halteres, which act as high-speed sensors of rotational movement and allow dipterans to perform advanced aerobatics. Diptera is a large order containing more than 150,000 species including horse-flies, crane flies, hoverflies, mosquitoes and others. Flies have a mobile head, with a pair of large compound eyes, and mouthparts designed for piercing and sucking (mosquitoes, black flies and robber flies), or for lapping and sucking in the other groups. Their wing arrangement gives them great manoeuvrability in flight, and claws and pads on their feet enable them to cling to smooth surfaces. Flies undergo complete metamorphosis; the eggs are often laid on the larval food-source and the larvae, which lack true limb ...
