Ahuehuete
''Taxodium mucronatum'', commonly known as Montezuma bald cypress, Montezuma cypress, or ahuehuete, is a species of ''Taxodium'' that is primarily native to Mexico and Guatemala, with a few populations in the southwestern United States. Ahuehuete is derived from the Nahuatl name for the tree, ''āhuēhuētl'', which means "upright drum in water" or "old man of the water." Description It is a large evergreen or semi-evergreen tree growing to tall and with a trunk of diameter (occasionally much more; see below). The leaves are spirally arranged but twisted at the base to lie in two horizontal ranks, long and broad. The cones are ovoid, long and broad. Unlike bald cypress and pond cypress, Montezuma cypress rarely produces cypress knees from the roots. Trees from the Mexican highlands achieve a notable stoutness. One specimen, the Árbol del Tule in Santa María del Tule, Oaxaca, Mexico, is the stoutest tree in the world with a diameter of . Several other specimens fro ...

Taxodium
''Taxodium'' is a genus of one to three species (depending on taxonomic opinion) of extremely flood-tolerant conifers in the cypress family, Cupressaceae. The name is derived from the Latin word ''taxus'', meaning " yew", and the Greek word ''εἶδος'' (''eidos''), meaning "similar to." Within the family, ''Taxodium'' is most closely related to Chinese swamp cypress (''Glyptostrobus pensilis'') and sugi (''Cryptomeria japonica''). Species of ''Taxodium'' occur in the southern part of the North American continent and are deciduous in the north and semi-evergreen to evergreen in the south. They are large trees, reaching tall and (exceptionally ) trunk diameter. The needle-like leaves, long, are borne spirally on the shoots, twisted at the base so as to appear in two flat rows on either side of the shoot. The cones are globose, diameter, with 10–25 scales, each scale with one or two seeds; they are mature in 7–9 months after pollination, when they disintegrate to ...

Árbol Del Tule
El Árbol del Tule ( Spanish for The Tree of Tule) is a tree located in the church grounds in the town center of Santa María del Tule in the Mexican state of Oaxaca, approximately east of the city of Oaxaca on the road to Mitla. It is a Montezuma cypress (''Taxodium mucronatum''), or ''ahuehuete'' (meaning "old man of the water" in Nahuatl). It has the stoutest tree trunk in the world. In 2001, it was placed on a UNESCO tentative list of World Heritage Sites, but was removed from the list in 2013. Dimensions and age In 2005, its trunk had a circumference of , equating to a diameter of , an increase from a measurement of m in 1982. However, the trunk is heavily buttressed, giving a higher diameter reading than the true cross-sectional of the trunk represents; when this is taken into account, the diameter of the 'smoothed out' trunk is . This is slightly wider than the next most stout tree known, a giant sequoia with a diameter. The height is difficult to measure due ...

Michele Tenore
Michele Tenore (5 May 1780 – 19 July 1861) was an Italian botanist active in Naples, Italy. Tenore studied at the University of Naples, receiving his medical degree in 1800. Tenore was a friend of botanists Domenico Maria Leone Cirillo (1739–1799) and Vincenzo Petagna (1734–1810). Tenore made numerous botanical excursions into Abruzzo and particularly Majella, and gave private courses in botany. In 1811, he succeeded Petagna to the university's chair in botany. Tenore helped establish the Botanical Garden of Naples, and became its director in 1810. He also served as president of the Accademia nazionale delle scienze, and served as president of the Accademia Pontaniana six times from the 1830s through the 1850s. In 1853, Tenore founded the Tenore prize, a prize still awarded from the Accademia Pontaniana.See the section "Accademia Pontaniana#Tenore prize, Tenore prize" in the Accademia Pontaniana entry.

Root
In vascular plants, the roots are the plant organ, organs of a plant that are modified to provide anchorage for the plant and take in water and nutrients into the plant body, which allows plants to grow taller and faster. They are most often below the surface of the soil, but roots can also be aerial root, aerial or aerating, that is, growing up above the ground or especially above water. Function The major functions of roots are absorption of water, plant nutrition and anchoring of the plant body to the ground. Types of Roots (major rooting system) Plants exhibit two main root system types: ''taproot'' and ''fibrous'', with variations like adventitious, aerial, and buttress roots, each serving specific functions. Taproot System Characterized by a single, main root growing vertically downward, with smaller lateral roots branching off. Examples. Dandelions, carrots, and many dicot plants. Fibrous RootSystem Consists of a network of thin, branching roots that spread out from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lower Rio Grande Valley
Lower Rio Grande Valley (), often referred to as the Rio Grande Valley (RGV) of South Texas, is a region located in the southernmost part of Texas, along the northern bank of the Rio Grande. It is also known locally as the Valley or the 956 (the area code for the region). It is a region spanning the border of Texas and Mexico located in a floodplain of the Rio Grande near its mouth. The region includes the southernmost tip of South Texas and a portion of northern Tamaulipas, Mexico. In the United States, it consists of the Brownsville-Harlingen and McAllen-Edinburg-Mission metropolitan areas, and the Rio Grande City-Roma and Raymondville micropolitan areas. In Mexico, it consists of the Matamoros, Río Bravo, and Reynosa metropolitan areas. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations. It is home to some of the poorest cities in the nation, as well as many unincorpo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disjunct Distribution
In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species' range. Range fragmentation Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new locations during bird or animal migrations, and those seeds can be deposited in new locations in fecal matter). Other conditions that can produce disjunct distributions include: flooding, or changes in wind, stream, and current flows, plus others such as anthropogenic introduction of alien introduced species either accid ...

Marsh
In ecology, a marsh is a wetland that is dominated by herbaceous plants rather than by woody plants.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p More in general, the word can be used for any low-lying and seasonally waterlogged terrain. In Europe and in agricultural literature low-lying meadows that require draining and embanked polderlands are also referred to as marshes or marshland. Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring (hydrosphere)
A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and Hydrostatics#Hydrostatic pressure, hydrostatic pressure. A spring produced by the emergence of Geothermal activity, geothermally heated groundwater is known as a hot spring. The yield (hydrology), yield of spring water varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the water table reaches above the surface level, or if the terrain depression (geology), depresses sharply. Springs may also be formed ...

Riparian Zone
A riparian zone or riparian area is the interface between land and a river or stream. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin ''wiktionary:ripa, ripa'', meaning "bank (geography), river bank". Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by aquatic plant, hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on terrestrial animal, terrestrial and semiaquatic fauna as well as aquatic ecosystems, including grasslands, woodlands, wetlands, and even non-vegetative areas. Riparian zones may be natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
