Free-air Concentration Enrichment
Free-Air Carbon dioxide Enrichment (FACE) is a method used by ecologists and plant biologists that raises the concentration of in a specified area and allows the response of plant growth to be measured. Experiments using FACE are required because most studies looking at the effect of elevated concentrations have been conducted in labs and where there are many missing factors including plant competition. Measuring the effect of elevated using FACE is a more natural way of estimating how plant growth will change in the future as the concentration rises in the atmosphere. FACE also allows the effect of elevated on plants that cannot be grown in small spaces (trees for example) to be measured. However, FACE experiments carry significantly higher costs relative to greenhouse experiments. Method Horizontal or vertical pipes are placed in a circle around the experimental plot, which can be between 1m and 30m in diameter, and these emit enriched air around the plants. The conce ...

Nevada Desert FACE Facility
Nevada ( ; ) is a state in the Western region of the United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast, and Utah to the east. Nevada is the 7th-most extensive, the 32nd-most populous, and the 9th-least densely populated of the U.S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area, including three of the state's four largest incorporated cities. Nevada's capital is Carson City. Las Vegas is the largest city in the state. Nevada is officially known as the "Silver State" because of the importance of silver to its history and economy. It is also known as the "Battle Born State" because it achieved statehood during the Civil War (the words "Battle Born" also appear on its state flag); as the "Sagebrush State", for the native plant of the same name; and as the " Sage-hen State". The name means "snowy" in Spanish, refe ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Boreal Forest
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce, Scandinavian and Finnish taiga consists of a m ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is inc ...

Meta-analysis
A meta-analysis is a statistical analysis that combines the results of multiple scientific studies. Meta-analyses can be performed when there are multiple scientific studies addressing the same question, with each individual study reporting measurements that are expected to have some degree of error. The aim then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived. Meta-analytic results are considered the most trustworthy source of evidence by the evidence-based medicine literature.Herrera Ortiz AF., Cadavid Camacho E, Cubillos Rojas J, Cadavid Camacho T, Zoe Guevara S, Tatiana Rincón Cuenca N, Vásquez Perdomo A, Del Castillo Herazo V, & Giraldo Malo R.

Duke Forest
Duke Forest is a forest managed by Duke University for research, teaching, and recreation. It is located in the edge of the Piedmont (United States) in Durham County, Orange County, and Alamance County in North Carolina. Four of its six divisions lie within the triangle formed by Durham, Chapel Hill, and Hillsborough. Description The Duke Forest is made up of six divisions which are fully accessible for teaching and research. Numerous forest types and ecosystems, soils, and previous land uses are represented on the forest. It is a resource unparalleled by any other university for its size, accessibility, length of management, and accumulation of long-term data (since 1931). Like much of the North Carolina Piedmont, the forest was farmed for cotton. After about a century of such management, the soils' native fertility was exhausted, and could no longer create the yields necessary to support farmers. Then, in 1929, the Great Depression began. Land was abandoned and secon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Richmond, New South Wales
Richmond is a town in New South Wales, in the local government area of the City of Hawkesbury. It is located 19 metres above sea level on the alluvial Hawkesbury River flats, at the foot of the Blue Mountains on the Cumberland Plain. It is about 65 km by road from Sydney and about 78 km by road from Lithgow. History The Darug people were the Aboriginal peoples to the area in 1788. The area was originally explored by British settlers in 1789 and the nearby eminence to the west of the Hawkesbury River was known by them as 'Richmond Hill'. The name was given by Governor Arthur Phillip, in honour of Charles Lennox, the third Duke of Richmond who was Master General of Ordnance in the Pitt administration. The local area was the third area to have European settlement in Australia after Sydney and Parramatta. The first 22 European settlers came to the area in 1794. They came to farm a total of in what is now Pitt Town Bottoms. They needed good farming land to help overcome ...

Cumberland Plain
The Cumberland Plain, an IBRA biogeographic region, is a relatively flat region lying to the west of Sydney CBD in New South Wales, Australia. Cumberland Basin is the preferred physiographic and geological term for the low-lying plain of the Permian-Triassic Sydney Basin found between Sydney and the Blue Mountains, and it is a structural sub-basin of the Sydney Basin. The Cumberland Plain has an area of roughly , which lies on Triassic shales and sandstones. Shaping the geography of Sydney, it extends from north of Windsor in the north, to Picton in the south; and from the Nepean-Hawkesbury River in the west almost to Sydney City's Inner West in the east. Much of the Sydney metropolitan area is located on the Plain. The Hornsby Plateau is located to the north and is dissected by steep valleys. The plain takes its name from Cumberland County, in which it is situated, one of the cadastral land divisions of New South Wales. The name ''Cumberland'' was conferred on the County ...

University Of Western Sydney
Western Sydney University, formerly the University of Western Sydney, is an Australian multi-campus university in the Greater Western region of Sydney, Australia. The university in its current form was founded in 1989 as a federated network university with an amalgamation between the Nepean College of Advanced Education and the Hawkesbury Agricultural College. The Macarthur Institute of Higher Education was incorporated in the university in 1989. In 2001, the University of Western Sydney was restructured as a single multi-campus university rather than as a federation. In 2015, the university underwent a rebranding which resulted in a change in name from the University of Western Sydney to Western Sydney University. It is a provider of undergraduate, postgraduate, and higher research degrees with campuses in Bankstown, Blacktown, Campbelltown, Hawkesbury, Liverpool, Parramatta, and Penrith.
