Neobuxbaumia Macrocephala (5754203358)
''Neobuxbaumia macrocephala'' is a long-lived columnar cactus Distribution It is endemic to the Tehuacán-Cuicatlán Valley in central Mexico. Within this region the species may be found on calcareous soil in xerophytic shrublands and tropical dry forest at an altitude of 1700 m above sea level. Description It is a branched columnar cactus that reaches between 7 and 15 m in height. The number of branches in an adult plant may vary from one to 10. Plants bear a reddish cephalium at the tip of each branch from which purple-red flowers emerge between May and June, during the end of the dry season. The species is hermaphroditic and its flowers are mainly nocturnal, opening at sunset (1900 h) and closing in the morning (1000 h). The bats ''Choeronycteris mexicana'' Tschudi, '' Leptonycteris curasoae'' Miller, and ''Leptonycteris nivalis'' (Saussure) are the main pollinators that promote seed production. Fruits ripen from June to August and are consumed by bats and bird species that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. 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. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in 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 where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

Endemism
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] |

Tropical Dry Forest
The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also tend to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowers
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) resulting from cross-pollination or allow selfing (fusion of sperm and egg from the same flower) when self-pollination occurs. There are two types of pollination: self-pollination and cross-pollination. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination happens in flowers where the stamen and carpel mature at the same time, and are positione ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Choeronycteris Mexicana
The Mexican long-tongued bat (''Choeronycteris mexicana'') is a species of bat in the family Phyllostomidae. It is monotypic, the only species within the genus ''Choeronycteris''. The species is found in El Salvador, Guatemala, Honduras, Mexico, and the United States. Etymology The genus name ''Choeronycteris'' is derived from the Greek words (pig) and (bat). The specific name ''mexicana'' correlates to its distribution. Description The Mexican long-tongued bat is medium in size in the family Phyllostomidae. Its pelage can be up to 7 mm long and is typically gray to brownish but can be paler on the shoulders. Wings are darker brownish gray with paler tips. The ears will also have the same coloration as the body and will vary in size. The tail is short. Body weight is 10-20 g, with a maximum of 25 g in pregnant females. The species has a distinctly elongated snout tipped with a roughly 5 mm-long nose-leaf. The tongue is long, narrow and extendible, specialized for nec ...

Leptonycteris Nivalis
The greater long-nosed bat or Mexican long-nosed bat (''Leptonycteris nivalis'') is a species of bat in the family Phyllostomidae. It is found in Mexico and the United States. It chiefly consumes pollen and nectar, particularly from agave plants and cacti. Its habitat includes desert scrub and open woodlands. It is threatened by habitat loss. Description They are sooty brown in color, with a darker dorsally and lighter ventrally. Individual hairs are white at the base, and silver at the tips. Their forearms are long.Baker, R. J., & Cockrum, E. L. (1966). Geographic and ecological range of the long-nosed bats, Leptonycteris. Journal of Mammalogy, 47(2), 329-331.

Lippia Graveolens
''Lippia graveolens'', a species of flowering plant in the verbena or vervain family, Verbenaceae, is native to the southwestern United States (Texas and southern New Mexico), Mexico, and Central America as far south as Nicaragua. Common names include: Mexican oregano, redbrush lippia, ('wild oregano'), scented lippia, and scented matgrass.
