Topographic Map Of The Area Around Isla Ángel De La Guarda
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically relief, even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form ( DEM). It is often considered to include the graphic representation of the lan ...

Grass
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family (biology), family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest :plant families, plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as forage, feed for livestock, meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti ...

Bursera Microphylla
''Bursera microphylla'', known by the common name elephant tree in English or 'torote' in Spanish, is a tree in the genus '' Bursera''. It grows into a distinctive sculptural form, with a thickened, water-storing or caudiciform trunk. It is found in the southwestern United States and northwestern Mexico. Distribution ''Bursera microphylla'' is the most northerly member of the Burseraceae in North America and also perhaps the most xeromorphic (desert-adapted) species within the genus as it thrives in the extremely arid desert hills and mountains in northwest Sonora. This tree is native to northwestern Mexico (Baja California, Baja California Sur, Sinaloa, Sonora and Zacatecas) and the southwestern United States (southern California and Arizona; especially in desert regions. This species can be found within Organ Pipe Cactus National Monument, Cabeza Prieta National Wildlife Refuge, Ironwood Forest National Monument, Sonoran Desert National Monument, El Pinacate y Gran Desier ...

Feral Cat
A feral cat or a stray cat is an unowned domestic cat (''Felis catus'') that lives outdoors and avoids human contact; it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens of generations and become a local apex predator in urban, savannah and bushland environments, and especially on islands where native animals did not evolve alongside predators. Some feral cats may become more comfortable with people who regularly feed them, but even with long-term attempts at socialization of animals, socialization, they usually remain aloof and reject human touch. Of the 700 million cats in the world, an estimated 480 million are feral. Feral cats are devastating to wildlife, and conservation biologists consider them to be one of the worst invasive species on Earth. They are included in the list of 100 of the World's Worst Invasive Alien Species, the world's 100 worst invasive alien species. Attempts to control feral cat ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/ricochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...

Neotoma Insularis
''Neotoma insularis'', the Angel de la Guarda woodrat, is a species of rodent in the family Cricetidae. It is found in the Mexican state of Baja California Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico. It is the northwesternmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of B ... on Angel de la Guarda Island. Description This species is described as being of medium body size with a relatively short tail. Classification This species, initially described as such by Townsend in 1912, was listed as a subspecies of '' Neotoma lepida'' by Burt in 1932. Patton et al. (2008) revised the systematic position of ''Neotoma lepida'' and found it to be a species complex, with ''N. l. insularis'' being readily distinct from ''N. lepida'', by means of mtDNA phylogeny and various morphological attributes, therefore reverting this population to its initial status ...

Angel Island Mouse
The Angel Island mouse (''Peromyscus guardia''), or La Guarda deermouse, is a species of rodent in the family Cricetidae. It is a species of the genus ''Peromyscus'', a closely related group of New World mice often called "deermice". Distribution It is endemic to Mexico, where it is historically known only from the island of Ángel de la Guarda and nearby islets in the northwestern Gulf of California, Baja California. The species is believed to be extirpated from the three smaller islands, and may be extinct on Ángel de la Guarda, as well. The species is threatened by predation by feral cats, and by competition from introduced rodents. Description The Angel Island mouse has pale grey-brown fur with white underparts and feet, and large, hairless ears. It is most readily distinguished from closely related species on the mainland by subtle characteristics of the skull, or through genetic or biochemical analysis. Adults range from in total length, including tails long. Female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Angel Island Chuckwalla
The Angel Island chuckwalla (''Sauromalus hispidus''), also known as the spiny chuckwalla, is a species of chuckwalla lizard belonging to the family Iguanidae endemic to Isla Ángel de la Guarda (Guardian Angel Island) in the Gulf of California. The species was transported to other islands by a tribe of the Seri as a potential food source. Taxonomy and etymology The generic name, ''Sauromalus'', is said to be a combination of two ancient Greek words: ''sauros'' meaning "lizard" and ''omalus'' meaning "flat". The proper ancient Greek word for "flat" is however ''homalos'' (ὁμαλός) or ''homalēs'' (ὁμαλής). Its specific name ''hispidus'' is Latin for "coarse" or "thorny" in reference to the spines on the chuckwalla's tail. The common name chuckwalla derives from the Shoshone word ''tcaxxwal'' or Cahuilla ''caxwal'', transcribed by Spaniards as ''chacahuala''.

Lizard
Lizard is the common name used for all Squamata, squamate reptiles other than snakes (and to a lesser extent amphisbaenians), encompassing over 7,000 species, ranging across all continents except Antarctica, as well as most Island#Oceanic islands, oceanic Archipelago, island chains. The grouping is Paraphyly, paraphyletic as some lizards are more closely related to snakes than they are to other lizards. Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as "legless lizards") have secondarily lost their legs, and have long snake-like bodies. Some lizards, such as the forest-dwelling ''Draco (genus), Draco'', are able to glide. They are often Territory (animal), territorial, the males fighting off other males and signalling, often with bright colours, to attract mates and to intimidate rivals. Lizards are mainly carnivorous, often b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
