Lake Junin Frog
''Telmatobius macrostomus'', also known as the Lake Junin (giant) frog or Andes smooth frog, is a very large and endangered species of frog in the family Telmatobiidae.Angulo, A. (2008). "Conservation needs of Batrachophrynus and Telmatobius frogs of the Andes of Peru." Conservation & Society 6(4): 328-333. DOI: 10.4103/0972-4923.49196 This completely aquatic frog is endemic to lakes and associated waters at altitudes of in the Andes of Junín and Pasco in central Peru. It has been introduced to slow-moving parts of the upper Mantaro River, although it is unclear if this population still persists.Sinsch, U. (1990). ''Froschlurche (Anura) der zentral-peruanischen Anden: Artdiagnose, Taxonomie, Habitate, Verhaltensökologie.'' Salamandra 26(2/3): 177- 214. Together with the closely related Amable Maria frog (''T. brachydactylus''), it is sometimes placed in the genus ''Batrachophrynus''.

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 in Koldenbüttel – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he g ...

Cloaca
In animal anatomy, a cloaca ( ), plural cloacae ( or ), is the posterior orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles and birds, and a few mammals ( monotremes, tenrecs, golden moles, and marsupial moles), have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have two or three separate orifices for evacuation. Excretory openings with analogous purpose in some invertebrates are also sometimes referred to as cloacae. Mating through the cloaca is known as cloacal copulation, commonly referred to as cloacal kiss. The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, marsupials, amphibians, and monotremes. Etymology The word is from the Latin verb ''cluo'', "(I) cleanse", thus the noun ''cloaca'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titicaca Water Frog
''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).

Baetidae
Baetidae is a family of mayfly, mayflies with about 1000 described species in 110 genera distributed worldwide. These are among the smallest of mayflies, adults rarely exceeding 10 mm in length excluding the two long slender tails and sometimes much smaller, and members of the family are often referred to as small mayflies or small minnow mayflies. Most species have long oval forewings with very few cross veins (see Comstock-Needham system) but the hindwings are usually very small or even absent. The males often have very large insect eye, eyes, shaped like turrets above the head (this is known as "turbinate condition"). Baetids breed in a wide range of waters from lakes and streams to ditches and even rain barrel, water butts. The nymph (biology), nymphs are strong swimmers and feed mainly on algae. The oldest members of the family date to the Late Cretaceous, with ''Myanmarella'' and ''Vetuformosa'' known from the Cenomanian aged Burmese amber, and ''Palaeocloeon'' from ...

Amphipod
Amphipoda is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods range in size from and are mostly detritivores or scavengers. There are more than 9,900 amphipod species so far described. They are mostly marine animals, but are found in almost all aquatic environments. Some 1,900 species live in fresh water, and the order also includes the terrestrial sandhoppers such as ''Talitrus saltator''. Etymology and names The name ''Amphipoda'' comes, via New Latin ', from the Greek roots 'on both/all sides' and 'foot'. This contrasts with the related Isopoda, which have a single kind of thoracic leg. Particularly among anglers, amphipods are known as ''freshwater shrimp'', ''scuds'', or ''sideswimmers''. Description Anatomy The body of an amphipod is divided into 13 segments, which can be grouped into a head, a thorax and an abdomen. The head is fused to the thorax, and bears two pairs of antennae and one pair of se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physidae
Physidae, common name the bladder snails, is a monophyletic taxonomic family of small air-breathing freshwater snails, aquatic pulmonate gastropod molluscs in the superfamily Lymnaeoidea .MolluscaBase eds. (2021). MolluscaBase. Physidae Fitzinger, 1833. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=160452 on 2021-06-26 Overview These fresh water snails are present in aquariums and ponds, as well as in wild areas. They are commonly referred to as tadpole snails or pouch snails. They eat algae, diatoms and detritus including dead leaves. The populations are regulated by the abundance of food and space. They are widespread, abundant, and tolerant to pollution. These snails are common in the North Temperate to Arctic Zones and throughout the Americas, in readily accessible habitats such as ditches, ponds, lakes, small streams, and rivers. The family has been recognized since the 19th century, and yet there has been no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universidad Mayor De San Marcos
The National University of San Marcos ( es, Universidad Nacional Mayor de San Marcos, link=no, UNMSM) is a public research university located in Lima, the capital of Peru. It is considered the most important, recognized and representative educational institution at the national level. At the continental level, it is the first officially established ( privilege by Charles V, Holy Roman Emperor) and the oldest continuously operating university in the Americas, which is why it appears in official documents and publications as "''University of Peru, Dean University of the Americas''". It had its beginnings in the general studies that were offered in the cloisters of the convent of the Rosario of the order of Santo Domingo —current Basilica and Convent of Santo Domingo— around 1548. Its official foundation was conceived by Fray Thomas de San Martín on May 12, 1551; with the decree of Emperor Carlos I of Spain and V of the Holy Roman Empire, in 1571, it acquired the degree of p ...

Lake Junín
Lake Junin (; Spanish ''Lago Junín'', named after the nearby town of Junin) or Chinchaycocha (possibly from Quechua ''chincha, chinchay'' north, northern, ''chinchay'' ocelot, ''qucha'' lake, lagoon, "northern lake" or "ocelot lake") is the largest lake entirely within Peruvian territory. Even though Lake Titicaca has a much larger area, its eastern half is located on Bolivian territory. Lake Junin is an important birdwatching destination in the country. Geography Most of the lake is located in the Junin Province of the Junin Region, its northwestern tip belongs to the Pasco Province which is in the Pasco Region. The surface elevation of the lake is located at above sea level.Shoobridge, D. (February 2006). Protected Area Profile Perú - Junín National Reserve, ParksWatch Perú.

Mantaro River
The Mantaro River ( es, Río Mantaro, qu, Hatunmayu) is a long river running through the central region of Peru. Its Quechua name means "great river". The word "Mantaro" may be a word originally from the Asháninka language, who live downstream along the Ene River. The Mantaro, along with the Apurimac River, are the sources of the Amazon River, depending on the criteria used for definition. Geography The river nominally has its source at Lake Junin, but tributaries above Lake Junin extend as much as 70 km farther upstream, for a total length of 809 km. The named tributaries of the river are the Cunas which enters the Mantaro at regional capital Huancayo, and the Kachimayu which flows near the city of Ayacucho. The upper Mantaro is 432 km long extending from Lake Junin to the Kachimayu inflow while the lower river shown on the map is 307 km long. The river runs through the provinces Junín, Yauli, Jauja, Concepción and Huancayo in the Junín Region, then t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
