Gastrotheca Ovifera
''Gastrotheca ovifera'' (vernacular names: pouched frog and giant marsupial frog; es, rana marsupial comun or ) is a species of frog in the family Hemiphractidae. It is endemic to northern Venezuela and is known from the Venezuelan Coastal Range, including Sierra de Aroa. ''Gastrotheca ovifera'' occurs in cloud forests at elevations of above sea level. It is associated with bromeliads where it hides, especially during dry periods. The eggs are carried on the female's back and have direct development (i.e., there is no free-living larval stage). This species can be locally abundant, but it has declined in many places where it used to be common. It is threatened by habitat loss caused by agriculture, logging, and infrastructure development. However, it has also declined in protected areas such as the Henri Pittier National Park Henri Pittier National Park is the oldest national park in Venezuela, originally created in 1937 under the name of ''Rancho Grande'' by decree of Presi ...

Ernst Haeckel
Ernst Heinrich Philipp August Haeckel (; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ''ecology'', '' phylum'', ''phylogeny'', and ''Protista.'' Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his ''Kunstformen der Natur'' ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance ( height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as '' orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called " metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying ob ...

Amphibians Described In 1854
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 ...

Endemic Fauna Of Venezuela
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastrotheca
''Gastrotheca'' is a genus of frogs in the family Hemiphractidae. They are found in Central America south of Costa Rica and in South America. Most species occur in the American Cordillera from southern Costa Rica to north-western Argentina. This genus makes up the bulk of marsupial frog diversity; formerly it was placed in the "Leptodactylidae" assemblage. Marsupial frogs are so-called because they possess a dorsal brood pouch. In some species the eggs are fertilized on the female's lower back, and are inserted in her pouch with the aid of the male's toes. The eggs remain in contact with the female's vascular tissue, which provides them oxygen. ''Gastrotheca guentheri'' (Guenther's marsupial frog) is the only known frog with true teeth in its lower jaw. '' Gastrotheca riobambae'' (Andean marsupial tree frog) is kept as pet and is used in scientific experiments. '' Gastrotheca gemma'' was additionally discovered in 2021. Species There are 74 species recognized in the genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Pittier National Park
Henri Pittier National Park is the oldest national park in Venezuela, originally created in 1937 under the name of ''Rancho Grande'' by decree of President Eleazar López Contreras. In 1953 the park was renamed in honor of Henri Pittier, a distinguished Swiss geographer, botanist and ethnologist, who arrived in Venezuela in 1917, classified more than 30,000 plants in the country and devoted many years studying the flora and fauna in the park. Henry Pittier National Park has the honor of having started the history of national parks of Venezuela. Its 107,800 hectares, located in the north of Aragua state, comprise most of the Araguan coast and mountainous area of Carabobo state. It also borders San Esteban National Park. Henri Pittier National Park is the largest among the national parks of the Venezuelan Coastal Range. The park consists of two geographic systems: a steep mountainous interior where there are more than 500 bird species and 22 endemic species and a coastal area with ...

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, intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bromeliad
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte '' Tillandsia'' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloud Forest
A cloud forest, also called a water forest, primas forest, or tropical montane cloud forest (TMCF), is a generally tropical or subtropical, evergreen, montane, moist forest characterized by a persistent, frequent or seasonal low-level cloud cover, usually at the canopy level, formally described in the '' International Cloud Atlas'' (2017) as silvagenitus. Cloud forests often exhibit an abundance of mosses covering the ground and vegetation, in which case they are also referred to as mossy forests. Mossy forests usually develop on the saddles of mountains, where moisture introduced by settling clouds is more effectively retained. Cloud forests are among the most biodiversity rich ecosystems in the world with a large amount of species directly or indirectly depending on them. Other moss forests include black spruce/ feathermoss climax forest, with a moderately dense canopy and a forest floor of feathermosses including '' Hylocomium splendens'', '' Pleurozium schreberi'' an ...

Kunstformen Der Natur
(known in English as ''Art Forms in Nature'') is a book of lithographic and halftone prints by German biologist Ernst Haeckel. Publication Originally published in sets of ten between 1899 and 1904 and collectively in two volumes in 1904, it consists of 100 prints of various organisms, many of which were first described by Haeckel himself. Over the course of his career, over 1000 engravings were produced based on Haeckel's sketches and watercolors; many of the best of these were chosen for , translated from sketch to print by lithographer Adolf Giltsch. A second edition of , containing only 30 prints, was produced in 1914. Themes According to Haeckel scholar Olaf Breidbach, the work was "not just a book of illustrations but also the summation of his view of the world." The over-riding themes of the plates are symmetry and le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
