Ficus Yoponensis
''Ficus yoponensis'' is a species of fig tree found in Central and South America. It can grow to heights of tall, having a trunk diameter of . The trunk is buttressed, light grey in colour and reasonably smooth. Its petioles are long, the stipules are straight and long. The leaves and stems are hairless. The leaves are long and wide, but larger in juveniles, being up to long and wide. The time at which they flower varies between individuals, but each tree tends to flower at a similar time each year. As in all figs, the flowers are enclosed inside the fig and can only be accessed by fig wasps, which enter to pollinate the flowers and lay their own eggs. The resulting fruit grows to in diameter and turns from green to purple with maturity. On average in Panama, ''F. yoponensis'' produce a new flush of leaves every 20 weeks and flower every 25 weeks. The species is similar in appearance to '' Ficus insipida'' but has smaller leaves, stipules and fruits and only occurs in pri ...

Howler Monkey
Howler monkeys (genus ''Alouatta'', monotypic in subfamily Alouattinae) are the most widespread primate genus in the Neotropical realm, Neotropics and are among the largest of the New World monkey, platyrrhines along with the muriquis (''Brachyteles''), the spider monkeys (''Ateles'') and woolly monkeys (''Lagotrix''). The monkeys are native to South America, South and Central American forests. They are famous for their Howling, howls, which can be heard from a distance through dense rain forest. Fifteen species are recognized. Previously classified in the Family (biology), family Cebidae, they are now placed in the family Atelidae. They are primarily folivores but also significant frugivores, acting as seed dispersal agents through their digestive system and their Animal locomotion, locomotion. Threats include human predation, habitat destruction, Wildlife trade, illegal wildlife trade, and Captivity (animal), capture for pets or zoo animals. Classification Anatomy and physiol ...

Trees Of Bolivia
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family (biology), family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses.

Culex Mollis
''Culex'' or typical mosquitoes are a genus of mosquitoes, several species of which serve as vectors of one or more important diseases of birds, humans, and other animals. The diseases they vector include arbovirus infections such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, but also filariasis and avian malaria. They occur worldwide except for the extreme northern parts of the temperate zone, and are the most common form of mosquito encountered in some major U.S. cities, such as Los Angeles. Etymology In naming this genus, Carl Linnaeus used the nonspecific Latin term for a midge or gnat: '. Description Depending on the species, the adult ''Culex'' mosquito may measure from . The adult morphology is typical of flies in the suborder Nematocera with the head, thorax, and abdomen clearly defined and the two forewings held horizontally over the abdomen when at rest. As in all Diptera capable of flight, the second pair of wings is reduced and modif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scirtidae
Scirtidae is a family of beetles (Coleoptera). These beetles are commonly referred to as marsh beetles, as the larvae are typically associated with stagnant water, but can be found in flowing water. Adults prefer decomposing plant material near the water's edge. More than an estimated 600 species are known worldwide, distributed among at least 60 genera. Genera These 81 genera belong to the family Scirtidae: * '' Accolabass'' Watts, 2009 * '' Alpestriscyphon'' Watts, Cooper & Libonatti, 2020 * '' Amplectopus'' Sharp, 1886 * '' Anocyphon'' Watts, Cooper & Libonatti, 2020 * '' Anthocara'' Watts, Cooper & Libonatti, 2020 * '' Anticyphon'' Ruta, 2016 * '' Atopida'' White, 1846 * '' Austrocyphon'' Zwick, 2013 * '' Brachelodes'' Yablokov-Khnzorian, 1961 * '' Brachycyphon'' Fairmaire, 1896 * '' Byrrhopsis'' Champion, 1913 * '' Calvariopsis'' Ruta, 2019 * '' Calvarium'' Pic, 1918 * '' Chameloscyphon'' Watts, 2011 * '' Chilarboreus'' Ruta, 2011 * '' Contacyphon'' Des Gozis, 1886 * '' C ...

Phytotelmata
Phytotelma (plural phytotelmata) is a small water-filled cavity in a terrestrial plant. The water accumulated within these plants may serve as the habitat for associated fauna and flora. A rich literature in German summarised by Thienemann (1954) developed many aspects of phytotelm biology. Reviews of the subject by Kitching (1971) and Maguire (1971) introduced the concept of phytotelmata to English-speaking readers. A multi-authored book edited by Frank and Lounibos (1983)Frank, J.H. and Lounibos, L.P. (1983) ''Phytotelmata: Terrestrial plants as hosts for aquatic insect communities'', Plexus Press. dealt in 11 chapters with classification of phytotelmata, and with phytotelmata provided by bamboo internodes, banana leaf axils, bromeliad leaf axils, ''Nepenthes'' pitchers, ''Sarracenia'' pitchers, tree holes, and '' Heliconia'' flower bracts and leaf rolls. A classification of phytotelmata by Kitching (2000) recognizes five principal types: bromeliad tanks, certain carniv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L-gulonolactone Oxidase
L-Gulonolactone oxidase ( ECbr>1.1.3.8 is an enzyme that produces vitamin C. It is expressed in most mammals, but is non-functional in Haplorrhini (a suborder of primates, including humans), in some bats, and in guinea pigs. It catalyzes the reaction of L-gulono-1,4-lactone with oxygen to form L-xylo-hex-3-gulonolactone (2-keto-gulono-γ-lactone) and hydrogen peroxide. It uses FAD as a cofactor. The L-xylo-hex-3-gulonolactone then converts to ascorbic acid spontaneously, without enzymatic action. The structure of L-gulonolactone oxidase in rats helps identify characteristics of this enzyme. Gulonolactone oxidase deficiency The non-functional gulonolactone oxidase pseudogene (''GULOP'') was mapped to human chromosome 8p21, which corresponds to an evolutionarily conserved segment on either porcine chromosome 4 (SSC4) or 14 (SSC14). GULO produces the precursor to ascorbic acid, which spontaneously converts to the vitamin itself. The loss of activity of the gene encoding L-gul ...

Vitamin C
Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin found in citrus and other fruits, berries and vegetables. It is also a generic prescription medication and in some countries is sold as a non-prescription dietary supplement. As a therapy, it is used to prevent and treat scurvy, a disease caused by vitamin C deficiency. Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. It also functions as an antioxidant. Vitamin C may be taken by mouth or by intramuscular, subcutaneous or intravenous injection. Various health claims exist on the basis that moderate vitamin C deficiency increases disease risk, such as for the common cold, cancer or COVID-19. There are also claims of benefits from vitamin C supplementation in excess of the recommended d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascorbic Acid
Ascorbic acid is an organic compound with formula , originally called hexuronic acid. It is a white solid, but impure samples can appear yellowish. It dissolves freely in water to give mildly acidic solutions. It is a mild reducing agent. Ascorbic acid exists as two enantiomers (mirror-image isomers), commonly denoted "" (for "levo") and "" (for "dextro"). The isomer is the one most often encountered: it occurs naturally in many foods, and is one form (" vitamer") of vitamin C, an essential nutrient for humans and many animals. Deficiency of vitamin C causes scurvy, formerly a major disease of sailors in long sea voyages. It is used as a food additive and a dietary supplement for its antioxidant properties. The "" form ( erythorbic acid) can be made by chemical synthesis, but has no significant biological role. Etymology The term ''ascorbic'' means antiscruvy and denotes the ability to fight off scurvy. It is related to combating Vitamin C deficiency. History The antiscor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
