Western Cicada Killer
''Sphecius grandis'', also called the western cicada killer, is a species of cicada killer wasp (''Sphecius''). The western species shares the same nesting biology as its fellow species, the eastern cicada killer ('' S. speciosus''). ''S. grandis'', like all other species of the genus ''Sphecius'', mainly provides cicadas for its offspring. It forms nest aggregations and mates and broods once in a year, in July and early August. The wasp is on average to in length and is amber-yellow with yellow rings on its abdomen. Wasps in the genus ''Sphecius'' are not habitually aggressive and use their venom mainly to paralyse cicadas which they take back to their nests to feed their young. The females catch around four or more cicadas for provisioning, place them in brood cells and lay eggs in the cells. ''S. grandis'' is endemic to Central America, Mexico and the Western United States, and is found at a higher mean altitude than other species of ''Sphecius''. The western ci ...

Big Bend (Texas)
__NOTOC__ The Big Bend is part of the Trans-Pecos region in southwestern Texas, United States along the border with Mexico, north of the prominent bend in the Rio Grande for which the region is named. Here the Rio Grande passes between the Chisos Mountains in Texas and the Sierra Madre Oriental in Mexico as it changes from running east-southeast to north-northeast. The region covers three counties: Presidio County to the west, Brewster County to the east, and Jeff Davis County to the north. The region is rugged, sparsely populated Chihuahua Desert, including the Chisos Mountains, Chinati Mountains, and the Davis Mountains. The region has well over of public lands, including Big Bend National Park (801,163 acres) and Big Bend Ranch State Park (300,000 acres), Black Gap Wildlife Management Area (103,000 acres),Texas Parks and WildlifeBlack Gap Wildlife Management Area(accessed Oct 30, 2022) Chinati Mountains State Natural Area (39,000 acres)Texas Parks and Wildlife,hinati M ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermoregulation
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. The internal thermoregulation process is one aspect of homeostasis: a state of dynamic stability in an organism's internal conditions, maintained far from thermal equilibrium with its environment (the study of such processes in zoology has been called physiological ecology). If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. Humans may also experience lethal hyperthermia when the wet bulb temperature is sustained above for six hours. The opposite condition, when body temperature decreases below normal levels, is known as hypothermia. It results when the homeostatic c ...

Sphecius Spectabilis
Cicada killer wasps (genus ''Sphecius'') are large, solitary, ground-dwelling, predatory wasps. They are so named because they hunt cicadas and provision their nests with them, after stinging and paralyzing them. Twenty-one species worldwide are recognized. The highest diversity occurs in the region between North Africa and Central Asia. In North America, the term "cicada killer wasp" usually refers to the most well-known species, the eastern cicada killer (''S. speciosus''). A few other related genera also are sometimes referred to as "cicada killers", e.g. ''Liogorytes'' in South America and ''Exeirus'' in Australia. The use of cicadas as prey is in keeping with the typical behavior of the tribe Gorytini, which tend to specialize on various members of the Cicadomorpha as prey items. Species This list of species is probably complete as of March 31, 2009. It has been adapted from thCatalog of ''Sphecius'' species(California Academy of Sciences). Notable subspecies are also ...

Milligram
The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'. The kilogram is defined in terms of the second and the metre, both of which are based on fundamental physical constants. This allows a properly equipped metrology laboratory to calibrate a mass measurement instrument such as a Kibble balance as the primary standard to determine an exact kilogram mass. The kilogram was originally defined in 1795 as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum ''Kilogramme des Archives'' replaced it as the standard of mass. In 1889, a cylinder of platinum-iridium, the International Prototype of the Kilogram (IPK), became the standard of the unit of mass for t ...

Forewing
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the dragonflies and lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the wing base, so that a small downward movement of the wing base lifts the wing itself upward. Those i ...

Rufous
Rufous () is a color that may be described as reddish-brown or brownish-red, as of rust or oxidised iron. The first recorded use of ''rufous'' as a color name in English was in 1782. However, the color is also recorded earlier in 1527 as a diagnostic urine color. The word "rufous" is derived from the Latin ''rufus'', meaning "red", and is used as an adjective in the names of many animals—especially birds—to describe the color of their skin, fur, or plumage.
