Cochranella Mache
''Cochranella mache'', also known as the Mache glassfrog or Mache Cochran frog, is a species of frogs in the family Centrolenidae. It is found in the lowland forest and eastern slopes of Cordillera Mache–Chindul in the Esmeraldas Province, northwestern Ecuador, and in the western foothills of the Cordillera Occidental in Colombia ( Antioquia, Chocó, and Valle del Cauca Departments). Description Adult males measure and females in snout–vent length. The dorsum is green with numerous, small yellow dots. The upper lip has a narrow white line. The ventral surfaces of the extremities as well as the gular region are greenish blue. The iris is white and has fine black reticulations and a golden ring around the pupil. Reproduction The males call in vegetation overhanging rivulets, typically in the midstory vegetation some above ground. The call consists of two pulses lasting about 0.04 seconds and about 0.01 second apart, and with the dominant frequency of 5410 Hz. The a ...

Amplexus
Amplexus (Latin "embrace") is a type of mating behavior exhibited by some externally fertilizing species (chiefly amphibians and horseshoe crabs) in which a male grasps a female with his front legs as part of the mating process, and at the same time or with some time delay, he fertilizes the eggs, as they are released from the female's body. In amphibians, females may be grasped by the head, waist, or armpits, and the type of amplexus is characteristic of some taxonomic groups. Amplexus involves direct contact between male and female, distinguished from other forms of external fertilization, such as broadcast spawning, where sperm and eggs are freely shed into water without direct contact by individuals. In order for amplexus to be initiated, male frogs must first find a mate by attracting one through calls, typically in the evening. Once a male has successfully attracted a mate, the process of amplexus begins, while the unsuccessful males are forced to continue their search fo ...

Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Ecuador
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frogs Of South America
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an ex ...

Cochranella
''Cochranella'' is a genus of glass frogs, family Centrolenidae. They are found in Central America from Honduras southward to the Amazonian and Andean cloud forests of Colombia, Ecuador, Peru, and Bolivia. Etymology The generic name ''Cochranella'' honors Doris Mable Cochran, an American herpetologist. Accordingly, common name Cochran frogs has been coined for the genus. Taxonomy and systematics ''Cochranella'' was first described by Edward Harrison Taylor in 1951. The current delimitation of this genus follows from the work by Juan Manuel Guayasamin and his colleagues published in 2009 (with some later adjustments). These authors remedied the polyphyly of the genus by partitioning it into several new genera. The diagnostic characteristics of the genus are the following: (1) humeral spines are absent (small spine present in ''C. litoralis''); (2) digestive tract is white (translucent in ''Cochranella nola'') and the lobed liver is covered by a transparent hepatic peritoneum; ...

Pontificia Universidad Católica Del Ecuador
The Pontificia Universidad Católica del Ecuador (PUCE) (English: ''Pontifical Catholic University of Ecuador'') is a Pontifical Catholic university founded in 1946 in Quito, Ecuador. History The university opened in the fall of 1946, with Carlos María de la Torre, archbishop of Quito, officiating. Aurelio Espinosa Pólit of the Society of Jesus (Jesuits) was the first rector. That fall there were 54 students and jurisprudence was the single faculty. Pope Francis visited the campus of PUCE on his trip to South America in July 2015. Location The principal campus of the university is in Quito. Other campuses are in Ambato (established in 1982), Esmeraldas (1981), Ibarra (1976), Santo Domingo de los Colorados (1996), and a regional campus in the province of Manabí (1993). The campus in Cuenca later became the Universidad del Azuay. All branches follow the National System PUCE.

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 objects such ...

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] |
Ctenus Eating Cochranella Mache
''Ctenus'' is a genus of wandering spiders first described by Charles Athanase Walckenaer in 1805. It is widely distributed, from South America through Africa to East Asia. Little is known about the toxic potential of the genus ''Ctenus''; however, '' Ctenus medius'' has been shown to share some toxic properties with '' Phoneutria nigriventer'', such as proteolytic, hyaluronidase and phospholipase activities, in addition to producing hyperalgesia and edema. The venom of ''C. medius'' also interferes with the complement system in concentrations in which the venom of ''P. nigriventer'' is inactive, indicating that some species in the genus may have a medically significant venom. The venom of ''C. medius'' interferes with the complement component 3 (C3) of the complement system; it affects the central factor of the cascades of the complement, and interferes with the lytic activity of this system, which causes stronger activation and consumption of the complement components. Unlike ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
