Telmatobius Culeus
''Telmatobius culeus'', commonly known as the Titicaca water frog, is a medium-large to very large and endangered species of frog in the family Telmatobiidae. It is entirely aquatic and only found in the Lake Titicaca basin, including rivers that flow into it and smaller connected lakes like Arapa, Lagunillas and Saracocha, in the Andean highlands of Bolivia and Peru. In reference to its excessive amounts of skin, it has jokingly been referred to as the Titicaca scrotum (water) frog. It is closely related to the more widespread and semiaquatic marbled water frog (''T. marmoratus''),Victoriano, Muñoz-Mendoza, Sáez, Salinas, Muñoz-Ramírez, Sallaberry, Fibla and Méndez (2015).

Prague Zoo
Prague Zoological Garden (Czech: ''Zoologická zahrada hl. m. Prahy'') is a zoo in Prague, Czech Republic. It was opened in 1931 with the goal to "advance the study of zoology, protect wildlife, and educate the public" in the district of Troja in the north of Prague. In 2013, the zoo occupied with in use for exhibits, and housed around 5,000 animals from just 676 species, including 132 species listed as threatened. The zoo is rated as the seventh best zoo in the world by Forbes Travel Guide in 2007, and is rated as the fifth best in the world by TripAdvisor. The zoo has contributed significantly to saving Przewalski's horse; for many years, it was the leading breeder of the subspecies. The zoo director is Miroslav Bobek. History The idea for a zoological garden in Prague was first proposed in 1881 in a newspaper article by Count Sweerts-Spork, on the occasion of the marriage of Crown Prince Rudolf of Austria and Princess Stéphanie of Belgium. In 1919, at a meeting of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Junin Frog

Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as ...

Microhabitat
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 interio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isla Del Sol
Isla del Sol (''Island of the Sun'') is an island in the southern part of Lake Titicaca. It is part of Bolivia, and specifically part of the La Paz Department (Bolivia), La Paz Department. Geographically, the terrain is harsh; it is a rocky, hilly island with many eucalyptus trees. There are no motor vehicles or paved roads on the island. The main economic activity of the approximately 800 families on the island is farming, with fishing and tourism augmenting the subsistence economy. Of the several villages, Yumani and Challapampa are the largest. There are over 80 ruins on the island. Most of these date to the Inca period circa the 15th century AD. Archaeologists have discovered evidence that people lived on the island as far back as the third millennium BC. Many hills on the island contain agricultural terraces, which adapt steep and rocky terrain to agriculture. Among the ruins on the island are Titi Qala (Aymara language, Aymara ''titi'' Andean mountain cat; lead, lead-colored, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mini Submarine
A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-craft and the unsuccessful Welman submarine, were specifically designed with ...

Respiration (physiology)
In physiology, respiration is the movement of oxygen from the outside environment to the cells within Tissue (biology), tissues, and the transport, removal of carbon dioxide in the opposite direction that's to the environment. The physiological definition of respiration differs from the Cellular respiration, biochemical definition, which refers to a metabolic process by which an organism obtains energy (in the form of ATP and NADPH) by oxidizing nutrients and releasing waste products. Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the Diffusion#Diffusion vs. bulk flow diffusion, diffusion and transport of metabolites between the organism and the external environment. Gas exchanges in the lung occurs by ventilation and perfusion. Ventilation refers to the in and out movement of air of the lu ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

Intergrade
In zoology, intergradation is the way in which two distinct subspecies are connected via areas where populations are found that have the characteristics of both. There are two types of intergradation: primary and secondary intergradation. Primary intergradation This occurs in cases where two subspecies are connected via one or more intermediate populations, each of which is in turn intermediate to its adjacent populations and exhibits more or less the same amount of variability as any other population within the species. Adjacent populations and subspecies are subject to cline intergradation, and in these situations it is usually taken for granted that the clines are causally related (by natural selection) to environmental gradients.Mayr E, Ashlock PD (1991). ''Principles of Systematic Zoology''. Second edition. McGraw-Hill. . Secondary intergradation When contact between a geographically isolated subspecies is reestablished with the main body of the species or with another i ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
