Pteroptyx Tener
''Pteroptyx'' is a genus of fireflies in the subfamily Luciolinae found in Southeast Asia. It has long been noted for the ability to perform synchronous flashing, though not all species synchronize. These synchronizing species have been found on so-called 'firefly trees' and created a growing firefly-watching tour industry in some regions. Species of the genus have been identified in Malaysia, Thailand, the Philippines, and Hong Kong. Identification The genus ''Pteroptyx'' was first proposed by Ernest Olivier in 1902 for '' Luciola''-like species. He identified two species, ''Luciola malaccae'' and ''Luciola testacea,'' which were later reassigned to the ''Pteroptyx'' genus. Three subsequent species, ''P. tener'', ''P. bearni'', and ''P. valida'' were described by Olivier between 1907 and 1909. Much of the work revising the genera within ''Luciolinae'' has been done by Australian entomologist Lesley Ballantyne, beginning in 1970. The genus was originally defined based on c ...

Chaiyaphum Province
Chaiyaphum ( th, ชัยภูมิ, ) is one of Thailand's seventy-six provinces (''changwat''), located in central northeastern Thailand , also called Isan. Neighboring provinces are (from north clockwise) Khon Kaen, Nakhon Ratchasima, Lopburi, and Phetchabun. Toponymy The word ''chaiya'' originates from the Sanskrit word ''jaya'' meaning 'victory', and the word ''phum'' from Sanskrit ''bhumi'' meaning 'earth' or 'land'. Hence the name of the province literally means 'land of victory'. The Malay/Indonesian/Sanskrit word ''jayabumi'' is equivalent. Geography The province is bisected by the Phetchabun mountain range, with the highest elevation in the province at 1,222 m. The east of the province is part of the Khorat Plateau. The total forest area is or 31.4 percent of provincial area. Tat Ton National Park is in the northwest, featuring some scenic waterfalls and dry dipterocarp forests. The biggest attraction of the Sai Thong National Park in the west is the Sai Thong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Sequence Data
In genetics and biochemistry, sequencing means to determine the primary structure (sometimes incorrectly called the primary sequence) of an unbranched biopolymer. Sequencing results in a symbolic linear depiction known as a sequence which succinctly summarizes much of the atomic-level structure of the sequenced molecule. DNA sequencing DNA sequencing is the process of determining the nucleotide order of a given DNA fragment. So far, most DNA sequencing has been performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates. However, new sequencing technologies such as pyrosequencing are gaining an increasing share of the sequencing market. More genome data are now being produced by pyrosequencing than Sanger DNA sequencing. Pyrosequencing has enabled rapid genome sequencing. Bacterial genomes can be sequenced in a single run with several times cov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioluminescent Insects
Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic bacteria such as those from the genus ''Vibrio''; in others, it is autogenic, produced by the animals themselves. In a general sense, the principal chemical reaction in bioluminescence involves a light-emitting molecule and an enzyme, generally called luciferin and luciferase, respectively. Because these are generic names, luciferins and luciferases are often distinguished by the species or group, e.g. firefly luciferin. In all characterized cases, the enzyme catalyzes the oxidation of the luciferin. In some species, the luciferase requires other cofactors, such as calcium or magnesium ions, and sometime ...

Lampyridae Genera
The Lampyridae are a family of elateroid beetles with more than 2,000 described species, many of which are light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. Light production in the Lampyridae is thought to have originated as an honest 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'' 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 the location of the light organ varies among species and between sexes of the same species. Fireflies ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecotourism
Ecotourism is a form of tourism involving responsible travel (using sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s, ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Ecotourism may focus on educating travelers on local environments and natural surroundings with an eye to ecological conservation. Some include in the definition of ecotourism the effort to produce economic opportunities that make conservation of natural resources financially possible. Generally, ecotourism deals with interaction with biotic components of the natura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sundaic
Sundaland (also called Sundaica or the Sundaic region) is a biogeographical region of South-eastern Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower. It includes Borneo, Java, and Sumatra in Indonesia, and their surrounding small islands, as well as the Malay Peninsula on the Asian mainland. Extent The area of Sundaland encompasses the Sunda Shelf, a tectonically stable extension of Southeast Asia's continental shelf that was exposed during glacial periods of the last 2 million years. The extent of the Sunda Shelf is approximately equal to the 120-meter isobath. In addition to the Malay Peninsula and the islands of Borneo, Java, and Sumatra, it includes the Java Sea, the Gulf of Thailand, and portions of the South China Sea. In total, the area of Sundaland is approximately 1,800,000 km2. The area of exposed land in Sundaland has fluctuated considerably during the past recent 2 mi ...

Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing 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] |
Bangkok
Bangkok, officially known in Thai language, Thai as Krung Thep Maha Nakhon and colloquially as Krung Thep, is the capital and most populous city of Thailand. The city occupies in the Chao Phraya River delta in central Thailand and has an estimated population of 10.539 million as of 2020, 15.3 percent of the country's population. Over 14 million people (22.2 percent) lived within the surrounding Bangkok Metropolitan Region at the 2010 census, making Bangkok an extreme primate city, dwarfing Thailand's other urban centres in both size and importance to the national economy. Bangkok traces its roots to a small trading post during the Ayutthaya Kingdom in the 15th century, which eventually grew and became the site of two capital cities, Thonburi Kingdom, Thonburi in 1768 and Rattanakosin Kingdom (1782–1932), Rattanakosin in 1782. Bangkok was at the heart of the modernization of Siam, later renamed Thailand, during the late-19th century, as the country faced pressures from the ...

Luciola
''Luciola'' is a genus of "flashing" fireflies (family Lampyridae), especially well known from Japan. They are often called "Japanese fireflies", but their members range farther into Asia and reach southern Europe (Italy, France, Spain, Portugal, among other countries) and Africa. This genus is traditionally held to extend to Australia, but these species do not seem to belong herein (see below for details). Biological description Unlike some other fireflies, the females of ''Luciola'' are fully winged. Ecologically, the genus is remarkable in that the larvae of several species are aquatic. The adults of the typical ''Luciola'' are similar to those of ''Atyphella'' which was formerly included in this genus. They can be easily distinguished by the males' aedeagus however, which in ''Luciola'' proper has large lateral lobes that do not taper and have elongated, slender and flattened smaller lobes along their ventral margin. The middle lobe of the males' aedeagus is very slim and ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
