Isla Espíritu Santo
Isla Espíritu Santo is an uninhabited island in the Gulf of California, off the Mexican state of Baja California Sur. It is separated from Isla Partida by a narrow canal. Together, the islands are part of La Paz Municipality and are both a short boat trip from La Paz on the Baja California Peninsula. There was human presence of the island already about 9,000 years ago. Geography and geology Isla Espriritu Santo is located in the Sea of Cortez (Gulf of California), about to its southern tip from the port city of La Paz, Mexico. Together with its sister island Isla Partida, the islands are a rock formation created by a series of violent earthquakes and volcanic activity. As such, volcanic ash and lava make up the majority of their geologic composition. With fairly straight high ridges and low valleys, the islands resemble a horizontal rainbow with earthy tones. Espiritu has a land area of , and its highest elevation is . Partida has a land area of , and its highest elevati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexico, Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado River, Colorado, Fuerte River, Fuerte, Mayo River (Mexico), Mayo, Sinaloa River, Sinaloa, Sonora River, Sonora, and the Yaqui River, Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

World Network Of Biosphere Reserves
The UNESCO World Network of Biosphere Reserves (WNBR) covers internationally designated protected areas, known as biosphere reserves, which are meant to demonstrate a balanced relationship between people and nature (e.g. encourage sustainable development). They are created under the Man and the Biosphere Programme (MAB). Mission The World Network of Biosphere Reserves (WNBR) of the MAB Programme consists of a dynamic and interactive network of sites. It works to foster the harmonious integration of people and nature for sustainable development through participatory dialogue, knowledge sharing, poverty reduction, human well-being improvements, respect for cultural values and by improving society's ability to cope with climate change In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to E .. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtles
Turtles are an order (biology), order of reptiles known as Testudines, characterized by a special turtle shell, shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other Amniote, amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed Turtle shell#Carapace, carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scale (anatomy), scales made of keratin, the material of hair, horns, and claws. The carapace bon ...

Batoidea
Batoidea is a superorder of cartilaginous fishes, commonly known as rays. They and their close relatives, the sharks, comprise the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces. Anatomy Batoids are flat-bodied, and, like sharks, are cartilaginous fish, meaning they have a boneless skeleton made of a tough, elastic cartilage. Most batoids have five ventral slot-like body openings called gill slits that lead from the gills, but the Hexatrygonidae have six. Batoid gill slits lie under the pectoral fins on the underside, whereas a shark's are on the sides of the head. Most batoids have a flat, disk-like body, with the exception of the guitarfishes and sawfishes, while most sharks have a spindle-shaped body. Many species of batoid have developed their pe ...

Sharks
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used to refer to all extinct members of Chondrichthyes with a shark-like morphology, such as hybodonts and xenacanths. The oldest modern sharks are known from the Early Jurassic. They range in size from the small dwarf lanternshark (''Etmopterus perryi''), a deep sea species that is only in length, to the whale shark (''Rhincodon typus''), the largest fish in the world, which reaches approximately in length. Sharks are found in all seas and are common to depths up to . They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and freshwat ...

Cortez Rainbow Wrasse
The Cortez rainbow wrasse (''Thalassoma lucasanum'') is a species of wrasse native to the eastern Pacific Ocean from Baja California to Peru, as well as around the Galapagos Islands. It is a reef inhabitant, occurring in small schools from the surface to depths of , though rarely deeper than or shallower than . It is generally very common. It can also be found in the aquarium trade. This species can reach in total length. It feeds on small organisms such as crustaceans, plankton and fish eggs, and the young are cleaner fish Cleaner fish are fish that show a specialist feeding strategy by providing a service to other species, referred to as clients, by removing dead skin, ectoparasites, and infected tissue from the surface or gill chambers.

Moorish Idol
The Moorish idol (''Zanclus cornutus'') is a marine fish species, the sole extant representative of the family Zanclidae (from the Greek ζαγκίος, ''zagkios'', "oblique") in order Acanthuriformes. A common inhabitant of tropical to subtropical reefs and lagoons, the Moorish idol is notable for its wide distribution throughout the Indo-Pacific. A number of butterflyfishes (genus ''Heniochus'') closely resemble the Moorish idol. It is closely related to, if not a direct descendant of, the extinct ''Eozanclus brevirostris'', from the Middle Eocene of Monte Bolca. The Moorish idol got its name from the "Moors" of Africa, who purportedly believed the fish to be a bringer of happiness. Moorish idols are also a coveted aquarium fish but, despite their abundance and wide array of habitats, they are notoriously finicky and hard to adjust to captivity. Their omnivorous diet can be extremely difficult to replicate in aquaria, as the vegetation which they live on is normally exter ...

Trumpetfish
The trumpetfishes are three species of highly specialized, tubularly-elongated marine fishes in the genus ''Aulostomus'', of the monogeneric family Aulostomidae. The trumpetfishes are members of the order Syngnathiformes, together with the seahorses and the similarly built, closely related cornetfishes. The generic name, ''Aulostomus'', is a composite of two Greek words: ''aulos'', meaning flute, and ''stoma'', meaning mouth, because the species appear to have tubular snouts. "Flutemouth" is another less-common name for the members of the family (although this word is more often used to refer to closely related cornetfishes of the family Fistulariidae). Trumpetfishes are found in tropical waters worldwide, with two species in the Atlantic and one in the Indo-Pacific. They are mostly demersal reef-dwellers, where one species seems to prefer rocky substrate. They are relatively large for reef fish, where they reach almost 1 m in length. Bodies of trumpetfish are elongated, rigid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanford University Press
Stanford University Press (SUP) is the publishing house of Stanford University. It is one of the oldest academic presses in the United States and the first university press to be established on the West Coast. It was among the presses officially admitted to the Association of American University Presses (now the Association of University Presses) at the organization's founding, in 1937, and is one of twenty-two current member presses from that original group. The press publishes 130 books per year across the humanities, social sciences, and business, and has more than 3,500 titles in print. History David Starr Jordan, the first president of Stanford University, posited four propositions to Leland and Jane Stanford when accepting the post, the last of which stipulated, “That provision be made for the publication of the results of any important research on the part of professors, or advanced students. Such papers may be issued from time to time as ‘Memoirs of the Leland Stanf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarion Angelfish
The Clarion angelfish (''Holacanthus clarionensis'') is a species of marine ray-finned fish, a marine angelfish belonging to the family Pomacanthidae. It is found in the eastern Pacific Ocean, almost exclusively near islands off the Pacific coast of Mexico. Description The Clarion angelfish has a laterally compressed, quadrilateral body. It has a small mouth which is equipped with bristle like teeth. The juveniles have an overall colour of yellowish-orange on the body and fins; the body is marked with a number of blue vertical bars which fade and, eventually, disappear as the fish matures. The juveniles may also have blue lips and blue margins on the dorsal and anal fins. The adults have a brownish face, with the adjacent part of the body behind reddish orange and the posterior body being browner. The dorsal and anal fins are bright orange while the caudal fin is vermilion. The dorsal fin contains 14 spines and 17-19 soft rays while the anal fin has 3 spines and 19-19 soft rays. ...

Parrotfish
Parrotfishes are a group of about 90 fish species regarded as a Family (biology), family (Scaridae), or a subfamily (Scarinae) of the wrasses. With about 95 species, this group's largest species richness is in the Indo-Pacific. They are found in coral reefs, rocky coasts, and seagrass beds, and can play a significant role in bioerosion. Description Parrotfish are named for their dentition, which is distinct from other fish, including other labrids. Their numerous teeth are arranged in a tightly packed mosaic on the external surface of their jaw bones, forming a parrot-like beak with which they rasp algae from coral and other rocky substrates (which contributes to the process of bioerosion). Maximum sizes vary within the family, with the majority of species reaching in length. However, a few species reach lengths in excess of , and the green humphead parrotfish can reach up to . The smallest species is the Cryptotomus roseus, bluelip parrotfish (''Cryptotomus roseus''), which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Espíritu Santo Antelope Squirrel
The Espíritu Santo antelope squirrel (''Ammospermophilus insularis'') is a species of antelope squirrel in the family Sciuridae. It is endemic to Mexico, where it is known only from the island of Espíritu Santo in the Gulf of California. The species was originally described by Edward William Nelson and Edward Alphonso Goldman in 1909 as a subspecies of the white-tailed antelope squirrel (''Ammospermophilus leucurus''), a wide-ranging species in the southwestern U.S. and Mexico. In 1938, Arthur H. Howell elevated the subspecies to full species status, on the basis of slightly larger skull proportions and the absence or reduction of the third upper premolar. Studies of DNA and chromosomes have variously suggested close relationships with Harris's antelope squirrel Harris's antelope squirrel (''Ammospermophilus harrisii'') is a species of rodent in the family Sciuridae. It is found in Arizona and New Mexico in the United States, and in Sonora in Mexico. They are adapted to h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
