Hyalinobatrachium Orientale
''Hyalinobatrachium orientale'' is a species of glass frog in the family Centrolenidae. It is found on the island of Tobago and in eastern Venezuela ( Paria Peninsula and Sierra de Lema). Its common name is eastern glass frog (in Spanish ''ranita de cristal oriental''). The Tobagonian population has been described as subspecies In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed.

Juan A
''Juan'' is a given name, the Spanish and Manx versions of ''John''. It is very common in Spain and in other Spanish-speaking communities around the world and in the Philippines, and also (pronounced differently) in the Isle of Man. In Spanish, the diminutive form (equivalent to ''Johnny'') is , with feminine form (comparable to ''Jane'', ''Joan'', or ''Joanna'') , and feminine diminutive (equivalent to ''Janet'', ''Janey'', ''Joanie'', etc.). Chinese terms * ( or 娟, 隽) 'beautiful, graceful' is a common given name for Chinese women. * () The Chinese character 卷, which in Mandarin is almost homophonic with the characters for the female name, is a division of a traditional Chinese manuscript or book and can be translated as 'fascicle', 'scroll', 'chapter', or 'volume'.

Heliconia
''Heliconia'', derived from the Greek word (), is a genus of flowering plants in the monotypic family Heliconiaceae. Most of the ca 194 known species are native to the tropical Americas, but a few are indigenous to certain islands of the western Pacific and Maluku. Many species of ''Heliconia'' are found in the tropical forests of these regions. Most species are listed as either vulnerable or data deficient by the IUCN Red List of threatened species. Several species are widely cultivated as ornamentals, and a few are naturalized in Florida, Gambia, and Thailand. Common names for the genus include lobster-claws, toucan beak, wild plantain, or false bird-of-paradise. The last term refers to their close similarity to the bird-of-paradise flowers ('' Strelitzia''). Collectively, these plants are also simply referred to as "heliconias". Description These herbaceous plants range from 0.5 to nearly 4.5 m (1.5–15 ft) tall, depending on the species. The simple leaves of thes ...

Taxa Named By Juan A
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Venezuela
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Hyalinobatrachium
''Hyalinobatrachium'' is a genus of glass frogs, family Centrolenidae. They are widely distributed in the Americas, from tropical Mexico to southeastern Brazil and Argentina. Taxonomy and systematics The genus is currently defined to include ''Hyalinobatrachium fleischmanni'' and its closest relatives. Its sister taxon is ''Celsiella''. Some species formerly in this genus are now in '' Vitreorana'' or '' Teratohyla''. Description ''Hyalinobatrachium'' have a bulbous liver covered by white pigment, a transparent parietal peritoneum, and lack a humeral spine in adult males. The bones are white in living animals. Males usually call from the underside of leaves. Females deposit one layer of eggs on the underside of leaves. Species As of March 2022, these species are included in the genus: * '' Hyalinobatrachium adespinosai'' Guayasamin, Vieira, Glor, and Hutter, 2019 * '' Hyalinobatrachium anachoretus'' Twomey, Delia, and Castroviejo-Fisher, 2014 * '' Hyalinobatrachium aureoguttatum ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Frog
The glass frogs belong to the amphibian family Centrolenidae ( order Anura). While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent, giving the glass frog its common name. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin. When active their blood makes them visible; when sleeping most of the blood is concealed in the liver, hiding them. Glass frogs are arboreal, living mainly in trees, and only come out for mating season. Their transparency conceals them very effectively when sleeping on a green leaf, as they habitually do. Taxonomy The first described species of Centrolenidae was the "giant" '' Centrolene geckoideum'', named by Marcos Jiménez de la Espada in 1872, based on a specimen collected in northeastern Ecuador. Several species were described in subsequent years by different herpetologists (including G. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish (language)
Spanish ( or , Castilian) is a Romance language of the Indo-European language family that evolved from colloquial Latin spoken on the Iberian peninsula. Today, it is a global language with more than 500 million native speakers, mainly in the Americas and Spain. Spanish is the official language of 20 countries. It is the world's second-most spoken native language after Mandarin Chinese; the world's fourth-most spoken language overall after English, Mandarin Chinese, and Hindustani (Hindi-Urdu); and the world's most widely spoken Romance language. The largest population of native speakers is in Mexico. Spanish is part of the Ibero-Romance group of languages, which evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. The oldest Latin texts with traces of Spanish come from mid-northern Iberia in the 9th century, and the first systematic written use of the language happened in Toledo, a prominent city of the ...
