Magdalena Transition
The Magdalena Transition is a marine ecoregion in the eastern Pacific Ocean. It includes the coastal waters along the southwestern Baja California Peninsula, extending from Punta Abreojos in the north to Cabo San Lucas at the peninsula's southern tip. The ecoregion includes San Ignacio Lagoon and Magdalena Bay. These lagoons include some of the northernmost mangroves on the Pacific Coast of North America.

Marine Ecoregion
A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics. Introduction A more complete definition describes them as “Areas of relatively homogeneous species composition, clearly distinct from adjacent systems” dominated by “a small number of ecosystems and/or a distinct suite of oceanographic or topographic features”. Ecologically they “are strongly cohesive units, sufficiently large to encompass ecological or life history processes for most sedentary species.”Spalding, Mark D., Helen E. Fox, Gerald R.

Bioscience Vol. 57 No. 7, July/August 2007, pp. 573–58/ref> Marine Ecoregions of the World—MEOW The global classification system Marine Ecoregions of the World—MEOW was devised by an international team, including major conservation organizations, academic institutions and ...

Rains (2006) An isolated hill, high, rises a few miles behind the town, and is a conspicuous landmark for sailors. Several lighthouses are situated near the town. was named by Francisco de Bolaños, whose expedition reached the headland, but no further. Myers (2004), pp. 209, 226. ' means "open your eyes", and refers to the treacherous sailing conditions, with many rocks and reefs. Myers (2004), pp. 209, 378. is reached by a long road with few features of interest. Palmerlee (2007) It comprises 500 houses, some grocery stores, an airstrip, a fish packing plant, a hardware store, churches, schools and a medical clinic.

Cabo San Lucas
Cabo San Lucas (, " Saint Luke Cape"), or simply just Cabo, is a resort city at the southern tip of the Baja California Peninsula, in the Mexican state of Baja California Sur. As at the 2020 Census, the population of the city was 202,694 inhabitants.2020 Census of Mexico. Cabo San Lucas together with the famous San José del Cabo are collectively known as Los Cabos. Together, they form a metropolitan area of 351,111 inhabitants.2020 Census of Mexico. Rated as one of Mexico's top five tourist destinations, Cabo is known for its beaches, scuba diving locations, Balnearios, the sea arch El Arco de Cabo San Lucas, and marine life. The Los Cabos Corridor has become a heavily trafficked vacation destination for tourists, with numerous resorts and timeshares along the coast between Cabo San Lucas and San José del Cabo. The waters around Cabo are home to marine wildlife including rays, sharks, mahi-mahi (dorado), and striped marlin. History Archaeological excavations have shown ...

San Ignacio Lagoon
San Ignacio Lagoon (Laguna San Ignacio) is a lagoon located in Mulegé Municipality of the Mexican state of Baja California Sur, 59 kilometers (37 mi) from San Ignacio, Mexico, and Highway 1. It is one of the winter sanctuaries of the eastern Pacific gray whales (''Eschrichtius robustus''). History San Ignacio Lagoon was discovered by a whaling captain, Jared Poole, brother-in-law to whaling captain Charles Melville Scammon. Scammon's visit to the lagoon in 1860 with six whaling vessels and subsequent whaling contributed to the near extinction of the Pacific Gray Whale. However, today the lagoon is one of the primary destinations for migrating Pacific gray whales. Today, it is an UNESCO World Heritage Site. It is where gray whales can breed and calve undisturbed by humans. The whales may reach 45 feet in length and 40 tons in weight. This lagoon is also a United Nations Biosphere Reserve, and a migratory bird sanctuary. Facts about San Ignacio Lagoon With a local community ...

Magdalena Bay
Magdalena Bay ( es, Bahía Magdalena) is a long bay in Comondú Municipality along the western coast of the Mexican state of Baja California Sur. It is protected from the Pacific Ocean by the unpopulated sandy barrier islands of Isla Magdalena and Isla Santa Margarita. Ecology This bay is particularly noted for the seasonal migration of the California gray whales that come here during winter to calve. The bay is also popular for commercial and sports fishing. Nearby mangrove swamps provide sanctuaries for sea birds. The bay includes the small fishing port of San Carlos, as well as Puerto López Mateos, which provides a good place to observe the whales. Islands Sandy barrier islands Isla Magdalena and Isla Santa Margarita separate the bay from the Pacific Ocean. Magdalena, mostly to the north and facing northwest, is a long, slender, segmented island that parallels the coast a few miles north. There is a small settlement, Puerto Magdalena mostly active during whale wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Whale
The gray whale (''Eschrichtius robustus''), also known as the grey whale,Britannica Micro.: v. IV, p. 693. gray back whale, Pacific gray whale, Korean gray whale, or California gray whale, is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of , a weight of up to and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age. The common name of the whale comes from the gray patches and white mottling on its dark skin. Gray whales were once called devil fish because of their fighting behavior when hunted. The gray whale is the sole living species in the genus ''Eschrichtius''. It was formerly thought to be the sole living genus in the family Eschrichtiidae, but more recent evidence classifies members of that family in the family Balaenopteridae. This mammal is descended from filter-feeding whales that appeared during the Neogene. The gray whale is distributed in an eastern North Pacific (North Am ...

Temperate Northern Pacific
The Temperate Northern Pacific is a biogeographic region of the Earth's seas, comprising the temperate waters of the northern Pacific Ocean. The Temperate Northern Pacific connects, via the Bering Sea, to the Arctic marine realm, which includes the polar waters of the Arctic Sea. To the south, it transitions to the tropical marine realms of the Pacific, including the Tropical Eastern Pacific along the Pacific coast of the Americas, the Eastern Indo-Pacific in the central Pacific Ocean, and the Central Indo-Pacific of the western Pacific basin. The Taiwan Strait forms the boundary between the Temperate Northern Pacific and the Central Indo-Pacific. Characteristic fauna include the Pacific salmon and trout ''( Oncorhynchus'' spp.), gray whale ''(Eschrichtius robustus)'', and North Pacific right whale ''(Eubalaena japonica).'' Subdivisions The Temperate Northern Pacific is further subdivided into marine provinces, and the marine provinces divided into marine ecoregions: Cold ...

Tropical Eastern Pacific
The Tropical Eastern Pacific is one of the twelve marine realms that cover the coastal waters and continental shelves of the world's oceans. The Tropical Eastern Pacific extends along the Pacific Coast of the Americas, from the southern tip of the Baja California Peninsula in the north to northern Peru in the south. It is bounded on the north by the Temperate Northern Pacific realm, and on the south by the Temperate South America realm. It includes a number of oceanic islands and oceanic island groups like the Galápagos Islands, Revillagigedo Islands, Cocos Island, and Clipperton Island. Clipperton has been labelled as a meeting point between the Oceanian realm and the Tropical Eastern Pacific realm. The Galápagos Islands are also believed to have much higher percentages of Indo-West Pacific species in their marine faunas when compared to the continental American coasts. A 2018 study revealed interconnectivity of species between the Line Islands, Hawaii and Clipperton, as w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecoregions Of Mexico
The following is a list of ecoregions in Mexico as identified by the World Wide Fund for Nature (WWF). A different system of ecoregional analysis is used by the Commission for Environmental Cooperation, a trilateral body linking Mexican, Canadian and United States environmental regime. Terrestrial ecoregions The terrestrial ecoregions of Mexico span two biogeographic realms - the Nearctic and Neotropic - which together constitute the entire biogeography of the Americas. Veracruz is the most biodiverse state with 10 ecoregions across 5 biomes and 2 realms. Chiapas comes in a close second with 10 ecoregions across 4 biomes in the same realm. By contrast, Morelos and Mexico City are the least biodiverse states with just 2 ecoregions each.
