Dalbergia Stevensonii
''Dalbergia stevensonii'', also called Honduras rosewood, is a Central American tree species in the legume family. It grows in broadleaf evergreen swamp forests in southern Belize and adjacent Guatemala and Mexico. The wood is highly valuable, which has led to population loss from illegal logging. __TOC__ Description It is a medium-sized tree, reaching 15–30 m in height and 91 cm in diameter. The bole tends to fork 6–8 m above the ground. Habitat ''Dalbergia stevensonii'' is found in seasonally and permanently flooded tropical evergreen broad-leaved lowland swamp forests. The rarity of this habitat limits the distribution of this species. It can be found in the Toledo district of Belize. In Honduras and Guatemala, it is found in broad-leaved forests; in Mexico, the species has been found in evergreen rainforests and oak forests. The population is likely to be shrinking from habitat loss and timber extraction. Information about the role of ''Dalbergia stevenson ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Belize
Belize (; bzj, Bileez) is a Caribbean and Central American country on the northeastern coast of Central America. It is bordered by Mexico to the north, the Caribbean Sea to the east, and Guatemala to the west and south. It also shares a water boundary with Honduras to the southeast. It has an area of and a population of 441,471 (2022). Its mainland is about long and wide. It is the least populated and least densely populated country in Central America. Its population growth rate of 1.87% per year (2018 estimate) is the second-highest in the region and one of the highest in the Western Hemisphere. Its capital is Belmopan, and its largest city is the namesake city of Belize City. Belize is often thought of as a Caribbean country in Central America because it has a history similar to that of English-speaking Caribbean nations. Indeed, Belize’s institutions and official language reflect its history as a British colony. The Maya civilization spread into the area of Beli ...

Guatemala
Guatemala ( ; ), officially the Republic of Guatemala ( es, República de Guatemala, links=no), is a country in Central America. It is bordered to the north and west by Mexico; to the northeast by Belize and the Caribbean; to the east by Honduras; to the southeast by El Salvador and to the south by the Pacific Ocean. With an estimated population of around million, Guatemala is the most populous country in Central America and the 11th most populous country in the Americas. It is a representative democracy with its capital and largest city being Nueva Guatemala de la Asunción, also known as Guatemala City, the most populous city in Central America. The territory of modern Guatemala hosted the core of the Maya civilization, which extended across Mesoamerica. In the 16th century, most of this area was conquered by the Spanish and claimed as part of the viceroyalty of New Spain. Guatemala attained independence in 1821 from Spain and Mexico. In 1823, it became part of the Fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and demand for pasture for ...

Nitrogen Fixation
Nitrogen fixation is a chemical process by which molecular nitrogen (), with a strong triple covalent bond, in the air is converted into ammonia () or related nitrogenous compounds, typically in soil or aquatic systems but also in industry. Atmospheric nitrogen is molecular dinitrogen, a relatively nonreactive molecule that is metabolically useless to all but a few microorganisms. Biological nitrogen fixation or ''diazotrophy'' is an important microbials mediated process that converts dinitrogen (N2) gas to ammonia (NH3) using the nitrogenase protein complex (Nif). Nitrogen fixation is essential to life because fixed inorganic nitrogen compounds are required for the biosynthesis of all nitrogen-containing organic compounds, such as amino acids and proteins, nucleoside triphosphates and nucleic acids. As part of the nitrogen cycle, it is essential for agriculture and the manufacture of fertilizer. It is also, indirectly, relevant to the manufacture of all nitrogen chemical c ...

Marimba
The marimba () is a musical instrument in the percussion family that consists of wooden bars that are struck by mallets. Below each bar is a resonator pipe that amplifies particular harmonics of its sound. Compared to the xylophone, the timbre of the marimba is warmer, deeper, more resonant, and more pure. It also tends to have a lower range than that of a xylophone. Typically, the bars of a marimba are arranged chromatically, like the keys of a piano. The marimba is a type of idiophone. Today, the marimba is used as a solo instrument, or in ensembles like orchestras, marching bands (typically as a part of the front ensemble), percussion ensembles, brass and concert bands, and other traditional ensembles. Etymology and terminology The term ''marimba'' refers to both the traditional version of this instrument and its modern form. Its first documented use in the English language dates back to 1704. The term is of Bantu origin, deriving from the prefix meaning 'many' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xylophone
The xylophone (; ) is a musical instrument in the percussion family that consists of wooden bars struck by mallets. Like the glockenspiel (which uses metal bars), the xylophone essentially consists of a set of tuned wooden keys arranged in the fashion of the keyboard of a piano. Each bar is an idiophone tuned to a pitch of a musical scale, whether pentatonic or heptatonic in the case of many African and Asian instruments, diatonic in many western children's instruments, or chromatic for orchestral use. The term ''xylophone'' may be used generally, to include all such instruments such as the marimba, balafon and even the semantron. However, in the orchestra, the term ''xylophone'' refers specifically to a chromatic instrument of somewhat higher pitch range and drier timbre than the marimba, and these two instruments should not be confused. A person who plays the xylophone is known as a ''xylophonist'' or simply a ''xylophone player''. The term is also popularly used to refer to ...

Dalbergia Nigra
''Dalbergia nigra'', commonly known as the Bahia rosewood, jacarandá-da-Bahia, Brazilian rosewood, Rio rosewood, jacarandá-do-brasil, pianowood, caviúna, graúna, jacarandá-una or obuina is a species of legume in the family Fabaceae. Description ''Dalbergia nigra'' produces a very hard and heavy wood, characteristically varied in colour from brick red through various shades of brown (medium to nearly black). Pieces that feature veins of black colouration called ''spider webbing'' or ''landscape grain'' are especially prized. Another distinguishing feature is its outstanding resonance. An evenly cut piece that is tapped emits a bright metallic ring that sustains. This property, combined with its beauty, has made Brazilian rosewood a favourite of musical instrument makers for centuries. Brazilian rosewood is highly resistant to insect attacks. There are many species in the genus ''Dalbergia'' that can be confused with ''Dalbergia nigra'', but the latter can be recognised by i ...
