Metabolism
Metabolism (, from el, μεταβολή ''metabolē'', "change") is the set of life-sustaining chemical reactions in organisms. The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks for proteins, lipids, nucleic acids, and some carbohydrates; and the elimination of metabolic wastes. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments. The word metabolism can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transportation of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary (or intermediate) metabolism. Metabolic reactions may be categorized as ''catabolic'' – the ''breaking down'' of compounds (for example, of glucose to pyruvate by ce ...

Torpor
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. The term "torpor" can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in "daily torpor". Animals that undergo daily torpor include birds (even tiny hummingbirds, notably Cypselomorphae) and some mammals, including many marsupial species, rodent species (such as mice), and bats. During the active part of their day, such animals maintain normal body temperature and activity levels, but their metabolic rate and body temperature drop during a portion of the day (usually night) to conserve energy. Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is kno ...

Hemoglobin
Hemoglobin (haemoglobin BrE) (from the Greek word αἷμα, ''haîma'' 'blood' + Latin ''globus'' 'ball, sphere' + ''-in'') (), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein present in red blood cells (erythrocytes) of almost all vertebrates (the exception being the fish family Channichthyidae) as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the respiratory organs (''e.g.'' lungs or gills) to the rest of the body (''i.e.'' tissues). There it releases the oxygen to permit aerobic respiration to provide energy to power functions of an organism in the process called metabolism. A healthy individual human has 12to 20grams of hemoglobin in every 100mL of blood. In mammals, the chromoprotein makes up about 96% of the red blood cells' dry content (by weight), and around 35% of the total content (including water). Hemoglobin has an oxygen-binding capacity of 1.34mL O2 per gram, which increases the total blood oxygen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hematocrit
The hematocrit () (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, measured as part of a blood test. The measurement depends on the number and size of red blood cells. It is normally 40.7–50.3% for males and 36.1–44.3% for females. It is a part of a person's complete blood count results, along with hemoglobin concentration, white blood cell count and platelet count. Because the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's hematocrit—the red blood cell volume percentage—can become a point of reference of its capability of delivering oxygen. Hematocrit levels that are too high or too low can indicate a blood disorder, dehydration, or other medical conditions. An abnormally low hematocrit may suggest anemia, a decrease in the total amount of red blood cells, while an abnormally high hematocrit is called polycythemia. Both are potentially life-threatening di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diptera
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 an estimated 1,000,000 species including horse-flies, crane flies, hoverflies and others, although only about 125,000 species have been described. 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 maneuverability 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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moche Big-eared Brown Bat
The Moche big-eared brown bat (''Histiotus mochica'') is a species of Vespertilionidae, vesper bat in the family Vespertilionidae. It is Endemism, endemic to coastal Peru. It is notable for its likely depiction in Moche culture, Moche Ceramic, ceramics over a millennium prior to its discovery to Western science in 2012 and scientific description in 2021. Taxonomy It is thought to be the sister species to the Humboldt big-eared brown bat (''H. humboldti''). Distribution It is restricted to the Sechura Desert, Peruvian desert, alongside several other bat species uniquely adapted to the harsh and arid habitat. This habitat also coincides with the historic extent of the Moche culture. Description It can be distinguished from other members of the genus ''Histiotus'' by its unique ears as well as its uniform brown Fur, pelage, in contrast to the multicolored pelage of other ''Histiotus'' species. Discovery and significance Bats were frequently represented in Moche culture, M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Big-eared Brown Bat
The southern big-eared brown bat (''Histiotus magellanicus'') is a species of bat from the family Vespertilionidae. Although current taxonomy treats the southern big-eared brown bat as a separate species, it is often treated as a subspecies of the small big-eared brown bat. It lives in the forests of southern Argentina and Chile; though the population of the bat in the southern part of its habitat is low, there are no major concerns to justify anything lower than a Least Concern rating in the IUCN Red List. Description This is a small bat, with a total length of and a wingspan of about . Adults weigh from . The fur is soft and dark brown in colour across the whole of the body, allowing it to be distinguished from other members of the same genus which much paler, often whitish, underparts. The ears are large and moderately elongated with a well-developed tragus and are separated on the head, rather than being connected by a band of skin as in some closely related species. The sk ...

Big-eared Brown Bat
The big-eared brown bat (''Histiotus macrotus'') is a species of vesper bat found in Argentina, Paraguay, and Chile. Taxonomy It was described as a new species in 1835 by German zoologist Eduard Friedrich Poeppig. Poeppig placed it in the genus ''Nycticeius'', with a binomial of ''N. macrotus''. By 1875, it was published under its current name combination, ''Histiotus macrotus''. Description It has large ears that exceed in length. The fur on its back is dark brown, while its belly fur is whitish. The flight membranes and ears are the darkest parts of its body. Range and habitat It is found in South America, where its range includes Argentina, Chile, and Paraguay. One study published that the species was found in Peru, though the image of the specimen did not appear to show the big-eared brown bat. It has been documented at a range of elevations from above sea level. Conservation As of 2016, it is evaluated as a least-concern species by the IUCN The International Union ...

Thomas's Big-eared Brown Bat
Thomas's big-eared brown bat (''Histiotus laephotis'') is a species of vesper bat found in South America. Taxonomy and etymology Thomas's big-eared brown bat was described as a new species in 1916 by British zoologist Oldfield Thomas. Thomas described the species based on specimens held by the Turin Museum of Natural History that had been collected by "Dr. Borelli", likely Dr. Alfredo Borelli, who furnished many biological specimens during this time from Argentina, Paraguay, and Bolivia. The holotype had been collected in Caiza, Bolivia, which is located in the Potosí Department of Southern Bolivia. Of the species name "''laephotis''", Thomas was not clear on its meaning, though he remarked that it " ada similar meaning" to the name ''histiotus'', which means "sail ear" (from Ancient Greek " ἱστός" meaning "mast" + " οὖς" meaning "ear"). A hypothesis for the etymology of ''laephotis'' is that it comes from Greek " λαιός" meaning "awkward" and " φως" meaning "l ...
