Sierra De La Laguna Dry Forests
The Sierra de la Laguna dry forests are a subtropical dry forest ecoregion of the southern Baja California Peninsula in Mexico. Geography The dry forests cover the lower elevations of the Sierra de la Laguna, from elevation. They are surrounded at lower elevations by the San Lucan xeric scrub, which lies between sea level and elevation. Above 800 meters elevation, the dry forests transition to the subhumid and temperate Sierra de la Laguna pine-oak forests. Climate The ecoregion has a warm and dry subtropical climate. Annual precipitation is generally less than 500 mm. The highest-rainfall months are late summer, from August to October with peak annual precipitation in September. Flora The characteristic vegetation is dry forest, composed of low trees and shrubs with an herbaceous understory. Many of the trees are deciduous, dropping their leaves during the dry season. The predominant tree species of the dry forests are the mauto (''Lysiloma divaricatum''), palo blanco ('' L. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
El Triunfo, Baja California Sur
El Triunfo is a town in La Paz Municipality, Baja California Sur, La Paz Municipality, Baja California Sur, Mexico, about 4.5 miles north of San Antonio, Baja California Sur, San Antonio. The town is located at an elevation of above sea level and has a population of 313 as 2020. It is a former Mining community, mining town. History The first mine in El Triunfo was established by Manuel de Ocio in the late 1700s. Ownership of the mine was temporarily transferred to the Spanish Crown at one point. However, the mine remained largely unsuccessful until 1878, where ownership of the mine was transferred. In 1862, silver and gold were discovered in the southern Baja California Sur mountains, leading miners from Mexico and the United States to rush to settle in El Triunfo in a gold rush. Many of the miners had participated in the California Gold Rush, 1849 California gold rush. In 1878, the mine was taken over by the British El Progreso Mining Company and became more successful.

Acorn Woodpecker
The acorn woodpecker (''Melanerpes formicivorus'') is a medium-sized woodpecker, long, with an average weight of . Taxonomy The acorn woodpecker was formally described in 1827 by the English naturalist William John Swainson under the binomial name ''Picus formicivorus'' from a specimen collected in Mexico. The specific epithet combines the Latin ''formica'' meaning "ant" with ''-vorus'' meaning "eating". The type locality is Temascaltepec in Mexico. The acorn woodpecker is one of 24 species now placed in the genus ''Melanerpes'' that was introduced by Swainson in 1832. Within ''Melanerpes'' the acorn woodpecker is sister to a clade containing two South American species: the white woodpecker (''Melanerpes candidus'') and the white-fronted woodpecker (''Melanerpes cactorum''). Seven subspecies are recognised: * ''M. f. bairdi'' Ridgway, 1881 – Oregon (USA) to north Baja California (Mexico) * ''M. f. angustifrons'' Baird, SF, 1870 – south Baja California (Mexico) * ' ...

Mule Deer
The mule deer (''Odocoileus hemionus'') is a deer indigenous to western North America; it is named for its ears, which are large like those of the mule. Two subspecies of mule deer are grouped into the black-tailed deer. Unlike the related white-tailed deer (''Odocoileus virginianus''), which is found throughout most of North America east of the Rocky Mountains and in the valleys of the Rocky Mountains from Idaho and Wyoming northward, mule deer are only found on the western Great Plains, in the Rocky Mountains, in the southwest United States, and on the west coast of North America. Mule deer have also been introduced to Argentina and Kauai, Kauai, Hawaii. Taxonomy Mule deer can be divided into two main groups: the mule deer (''sensu stricto'') and the black-tailed deer. The first group includes all subspecies, except ''O. h. columbianus'' and ''Sitka deer, O. h. sitkensis'', which are in the black-tailed deer group. The two main groups have been treated as separate species, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollinator
A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insects are the major pollinators of most plants, and insect pollinators include all families of bees and most families of aculeate wasps; ants; many families of flies; many lepidopterans (both butterflies and moths); and many families of beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds with long beaks; they pollinate a number of deep-throated flowers. Humans may also carry out artificial pollination. A pollinator is different from a pollenizer, a plant that is a source of pollen for the pollination process. Background Plants fall into pollination syndromes that reflect the type o ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferocactus
''Ferocactus'' is a genus of large barrel-shaped cacti, mostly with large spines and small flowers. There are about 30 species included in the genus. They are found in the southwestern United States and northwestern Mexico. Description The young specimens are columnar but as they grow older ribs form and they take on a barrel form. Most of the species are solitary but some, such as ''Ferocactus robustus'' and '' F. glaucescens'', have clustering habits. The flowers are pink, yellow, red or purple depending on the species, and the petals sometimes have a stripe of a darker colour. Habitat They are desert dwellers and can cope with some frost and intense heat. The typical habitat is hot and very arid, and the plants have adapted to exploit water movement to concentrate their biomass in areas where water is likely to be present. Like ''Sclerocactus'', ''Ferocactus'' typically grow in areas where water flows irregularly or depressions where water can accumulate for short periods ...
