Photinus Carolinus
''Photinus carolinus'' is a species of rover firefly whose mating displays of synchronous flashing have fascinated both scientists and tourists. As individual females synchronize with males nearby, waves of alternating bright light and darkness seem to travel across the landscape. Firefly displays typically occur in early June near Elkmont, Tennessee, in the Great Smoky Mountains National Park, near Gatlinburg. Description A typical ''Photinus'' is a "lightning-bug firefly" (as opposed to the so-called "glowworm firefly") because it emits light in its winged (imago) stage. Both male and female adults produce mating signals with an abdominal light organ or "lantern". Members of ''Photinus'' are called "rover fireflies" because typically males fly about singly, not in groups, flashing a species-specific pattern until a receptive female responds with her species-specific flashing signal. ''P. carolinus'' was the first North American species found to show synchronized flashing beha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to International Unio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rover Firefly
The rover fireflies (''Photinus'') are a genus of fireflies (family Lampyridae). They are the type genus of tribe Photinini in subfamily Lampyrinae. This genus contains, for example, the common eastern firefly (''P. pyralis''), the most common species of firefly in North America. Male ''Photinus'' beetles emit a flashing light pattern to signal for females. Illegitimate receivers, such as female ''Photuris'' beetles, identify these signals and use them to locate the male ''Photinus'', attract them with deceptive signals, and eat them. Systematics The closest living relative of the rover fireflies is not yet determined with certainty. In morphology, they resemble their predators, the Photurinae, but they are quite certainly not at all closely related as fireflies go. Rather, the genus ''Ellychnia'' is either the closest relative of ''Photinus'', or might even be included in it. ''Ellychnia'' are notable for having lost the ability to produce light again, and like the ancest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elkmont, Tennessee
Elkmont is a region situated in the upper Little River Valley of the Great Smoky Mountains of Sevier County, in the U.S. state of Tennessee. Throughout its history, the valley has been home to a pioneer Appalachian community, a logging town, and a resort community. Today, Elkmont is home to a large campground, ranger station, and historic district maintained by the Great Smoky Mountains National Park.Thomason, Phillip and Williams, Michael. . April–July 1993, pp. 7-13. PDF file. The Little River Lumber Company established the town of Elkmont in 1908 as a base for its logging operations in the upper Little River and Jakes Creek areas. By 1910, the company began selling plots of land to hunting and fishing enthusiasts from Knoxville, who established the "Appalachian Club" just south of the logging town. In 1912, a resort hotel, the Wonderland Park Hotel, was constructed on a hill overlooking Elkmont. A group of Knoxville businessmen purchased the Wonderland in 1919 and ...

Gatlinburg, Tennessee
Gatlinburg is a mountain resort city in Sevier County, Tennessee, United States. It is located southeast of Knoxville and had a population of 3,944 at the 2010 Census and a U.S. Census population of 3,577 in 2020. It is a popular vacation resort, as it rests on the border of Great Smoky Mountains National Park along U.S. Route 441, which connects to Cherokee, North Carolina, on the southeast side of the national park. Prior to incorporation, the town was known as White Oak Flats, or just simply White Oak. History Early history For centuries, Cherokee hunters, as well as other Native American hunters before them, used a footpath known as Indian Gap Trail to access the abundant game in the forests and coves of the Smokies. This trail connected the Great Indian Warpath with Rutherford Indian Trace, following the West Fork of the Little Pigeon River from modern-day Sevierville through modern-day Pigeon Forge, Gatlinburg, and the Sugarlands, crossing the crest of the Smokies a ...

Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage, the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.Carpenter, Geo. H., The Life-Story of Insects. Cambridge University Press 1913. May be downloaded from: https://www.gutenberg.org/ebooks/16410 or https://archive.org/details/thelifestoryofin16410gut In a member of the Ametabola or Hemimetabola, in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa, after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the only stage during which the insect is sexually mature and, if it is a winged species, has functional wings. The i ...

Photinus Carolinus Fireflies
Photinus (Greek Φωτεινός; died 376), was a Christian bishop of Sirmium in Pannonia Secunda (today the town Sremska Mitrovica in Serbia), best known for denying the incarnation of Christ, thus being considered a heresiarch by the Catholic Church. His name became synonymous in later literature for someone asserting that Christ was not God. His teachings are mentioned by various ancient authors, like Ambrosiaster (Pseudo-Ambrose), Hilary of Poitiers, Socrates Scholasticus, Sozomen, Ambrose of Milan, Augustine of Hippo, John Cassian, Sulpicius Severus, Jerome, Vigilius of Thapsus and many others. None of his writings are extant; his views must be reconstructed through his critics. Life Photinus grew up in Ancyra in Galatia, where he was a student and later a deacon of bishop Marcellus. Marcellus, in later life a staunch opponent of Arianism, was excommunicated and deposed in 336 but rehabilitated by the Synod of Serdica in 343, which also made Photinus bishop of S ...

Smoky Mountains
The Great Smoky Mountains (, ''Equa Dutsusdu Dodalv'') are a mountain range rising along the Tennessee–North Carolina border in the southeastern United States. They are a subrange of the Appalachian Mountains, and form part of the Blue Ridge Physiographic Province. The range is sometimes called the Smoky Mountains and the name is commonly shortened to the Smokies. The Great Smokies are best known as the home of the Great Smoky Mountains National Park, which protects most of the range. The park was established in 1934, and, with over 11 million visits per year, it is the most visited national park in the United States. The Great Smokies are part of an International Biosphere Reserve. The range is home to an estimated of old growth forest, constituting the largest such stand east of the Mississippi River. The cove hardwood forests in the range's lower elevations are among the most diverse ecosystems in North America, and the Southern Appalachian spruce-fir forest that coa ...

Degree Day
A degree day is a measure of heating or cooling. Total degree days from an appropriate starting date are used to plan the planting of crops and management of pests and pest control timing. Weekly or monthly degree-day figures may also be used within an energy monitoring and targeting scheme to monitor the heating and cooling costs of climate controlled buildings, while annual figures can be used for estimating future costs. A degree day is computed as the integral of a function of time that generally varies with temperature. The function is truncated to upper and lower limits that vary by organism, or to limits that are appropriate for climate control. The function can be estimated or measured by one of the following methods, in each case by reference to a chosen base temperature: * Frequent measurements and continuously integrating the temperature deficit or excess; * Treating each day's temperature profile as a sine wave with amplitude equal to the day's temperature variation, ...

Lampyridae
The Lampyridae are a family (biology), family of Elateroidea, elateroid beetles with more than 2,000 described species, many of which are bioluminescence, light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly crepuscular, during twilight, to attract mates. Light production in the Lampyridae is thought to have originated as an honest signal, honest Aposematism, warning signal that the larvae were distasteful; this was co-opted in evolution as a mating signal in the adults. In a further development, female fireflies of the genus ''Photuris'' mimic the flash pattern of ''Photinus (beetle), Photinus'' species to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. While all known fireflies glow as larvae, only some species produce light in their adult stage, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
