Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perennial Water
Perennial water body usually refers to mainly liquid fresh water, as opposed to sea and glaciers or other ice. Most frequently the term refers to running water (lotic ecosystems) as in perennial streams and large rivers, but the distinction between perennial and non-perennial water is of equal importance in lentic aquatic ecosystems, those that are associated with relatively still terrestrial waters such as lakes and ponds. Simplistically a perennial water body is one that keeps full or flowing throughout the year for all or most years, but in practice there are degrees and kinds of distinction. The definition is not precise, because most water bodies vary in fullness according to the season, and according to the heaviness of precipitation and other factors during any given year. Also, the water level in many such water bodies as do not actually dry out, may nonetheless drop so drastically that their surface area is greatly reduced. They even may be split into several separate water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michoacán
Michoacán, formally Michoacán de Ocampo (; Purépecha: ), officially the Free and Sovereign State of Michoacán de Ocampo ( es, Estado Libre y Soberano de Michoacán de Ocampo), is one of the 32 states which comprise the Federal Entities of Mexico. The state is divided into 113 municipalities and its capital city is Morelia (formerly called Valladolid). The city was named after José María Morelos, a native of the city and one of the main heroes of the Mexican War of Independence. Michoacán is located in Western Mexico, and has a stretch of coastline on the Pacific Ocean to the southwest. It is bordered by the states of Colima and Jalisco to the west and northwest, Guanajuato to the north, Querétaro to the northeast, the State of México to the east, and Guerrero to the southeast. The name Michoacán is from Nahuatl: ''Michhuahcān'' from ''michhuah'' ("possessor of fish") and -''cān'' (place of) and means "place of the fishermen" referring to those who fish on La ...

Lerma River
The Lerma River ( es, Río Lerma) is Mexico's second longest river. It is a river in west-central Mexico that begins in Mexican Plateau at an altitude over above sea level, and ends where it empties into Lake Chapala, Mexico's largest lake, near Guadalajara, Jalisco. Lake Chapala is the starting point of Río Grande de Santiago, which some treat as a continuation of the Lerma River. In combination, the two are often called the Lerma Santiago River ( es, Río Lerma Santiago). The Lerma River is notorious for its pollution, but the water quality has demonstrated considerable improvement in recent years due mostly to government environmental programs and through massive upgrading projects of sanitation works. Course The Lerma River originates from the Lerma lagoons near Almoloya del Río, on a plateau more than above sea level, and southeast of Toluca. The lagoons receive their water from springs rising from basaltic volcanics that flow down from Monte de Las Cruces. These are lo ...

Ramsar Wetland
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Conference of the Contracting Parties (COP), the policy-making organ of the convention which adopts decisions (resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. COP12 was held in Punta del Este, Uruguay, in 2015. COP13 was held in Dubai, United Arab Emirates, in October 2018. List of wetlands of international importance The list of wetlands of international importance included 2,331 Ramsar sites in May 2018 covering over .

Zacapu Shiner
The Zacapu shiner (''Notropis grandis'') is a small North American freshwater fish, where it is known only from the Zacapu Lagoon and its outlet in Michoacán, Mexico. The Zacapu shiner is a member of the '' Notropis calientis'' species complex along with the Ameca shiner, the Durango shiner and the Maravatio shiner, the latter being described concurrently with ''N. grandis''. Description The Zacapu shiner is differentiated from the other members of the ''N. calientis'' species complex by having 6, rarely 7, branched rays in the anal fin and 8 pelvic fin rays and by normally having 42 lateral line scales. It has a yellowish to light brown body with a dark lateral stripe which widens to form a slightly convex part from near the pectoral fin origin to the dorsal fin origin, becoming narrower and darker towards the rear. There is a dark marking on the caudal peduncle and at the origin of the caudal fin. There are fine markings around the base of the dorsal fin and the head is pigme ...

Allotoca Zacapuensis
''Allotoca'' is a genus of splitfins that are endemic to west-central and southwest Mexico, where restricted to the Lerna–Chapala– Grande de Santiago, Ameca and Balsas river basins, as well as various endorheic lake basins in Michoacán and Jalisco ( Pátzcuaro, Zirahuén, Cuitzeo, Magdalena and others). All ''Allotoca'' species are seriously threatened. The largest ''Allotoca'' is up to long, but most species only reach between half and three-quarter that size. Unusually, ''A. catarinae'' is probably the result of an ancient translocation by humans in the pre-Columbian era (similar ancient human-assisted translocations are known from certain birds in Mexico). The translocation happened at least 700 years ago and most likely about 1900 years ago. The ancestral species then evolved into ''A. catarinae'' at its new isolated location in the Cupatitzio River, a tributary of the Balsas River. Species FishBase recognizes eight species in this genus, but their taxonom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambarellus Zacapuensis
''Cambarellus zacapuensis'', also known as Zacapu acocil or Zacapu dwarf crayfish, is a small crustacean endemic to the Angulo River basin, observed mainly in Zacapu Lagoon. Description The Zacapu acocil is a species morphologically very similar to the Chapala acocil (''Cambarellus chapalanus''). Males of ''C. zacapuensis'' have an average length of 26 millimeters, with a 12 millimeters long and 5.5 millimeters wide cephalothorax, while females have an average length of 32 millimeters, with a 14.5 millimeters long and 7 millimeters wide cephalothorax. ''C. zacapuensis'' has a pigmented body, well-developed eyes, and a rostrum with marginal spines. Its shell lacks a cervical spine or a branchial spine. Conservation status and habitat The Zacapu acocil is found mainly in Zacapu Lagoon and in some of its drains such as the Angulo River. It is usually found at a shallow depth, between submerged roots and in the aquatic substrate. The introduction of invasive species such as com ...

Anderson's Salamander
Anderson's salamander (''Ambystoma andersoni'') is a neotenic salamander from Zacapu Lagoon in the Mexican state of Michoacán. This salamander is a relatively recent discovery, first described by Branden and Krebs in 1984. ''Ambystoma andersoni'' is named after James Anderson, a herpetologist with the American Museum of Natural History, who did extensive fieldwork studying ''Ambystoma'' and other amphibians and reptiles in Mexico. Like all neotenic ''Ambystoma'' species, ''A. andersoni'' retains its larval features into adulthood. The mature salamander has medium-sized external gills with bright red filaments, and a prominent caudal fin. It has a large head and small limbs, as do the larvae. Its coloration is a strange pattern of black blotches on a red-brown base. The salamanders are totally aquatic and spend their whole lives in the same body of water. Habitat Lake Zacapu is small lake near Zacapu, sitting at an altitude of 2000 meters. The lake is located within the Mesa ...

Protected Areas Of Michoacán
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Geography Of Michoacán
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
