Protopannaria Campbellensis
''Protopannaria campbellensis'' is a rare species of lichen in the family Pannariaceae. It is found in the southern New Zealand shelf islands. It is unique due to its specific structure and lack of lichen products, which are typically found in related species. The lichen is found in wet grasslands and upland peat bogs. Taxonomy ''Protopannaria campbellensis'' was first described as a new species by Dag Øvstedal and Alan Fryday in 2011. The type specimen was discovered on the summit of Mount Dumas on Campbell Island, New Zealand, at an altitude of . The species name, ''campbellensis'', refers to its discovery location. Description This lichen species has a brown, thallus that forms tufts up to across. It consists of overlapping , with the inner parts being erect, , and 4–5 mm high. The marginal squamules are and can be up to 2 mm wide with irregular projections. The (the photosynthetic partner) in this lichen is a cyanobacterium called '' Nostoc'', ...

Nostoc
''Nostoc'', also known as star jelly, troll’s butter, spit of moon, fallen star, witch's butter (not to be confused with the fungi commonly known as witches' butter), and witch’s jelly, is the most common genus of cyanobacteria found in various environments that may form colonies composed of filaments of moniliform cells in a gelatinous sheath of polysaccharides. ''Nostoc'' is a genus of photosynthetic, Gram-negative cyanobacteria that can be found in both terrestrial and aquatic environments. It may also grow symbiotically within the tissues of plants, providing nitrogen to its host through the action of terminally differentiated cells known as heterocysts. ''Nostoc'' is a genus that includes many species that are diverse in morphology, habitat distribution, and ecological function. ''Nostoc'' can be found in soil, on moist rocks, at the bottom of lakes and springs, and rarely in marine habitats. It may also be found in terrestrial temperate, desert, tropical, or polar env ...

Montane
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acidic Soil
Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics. pH is defined as the negative logarithm (base 10) of the activity of hydronium ions ( or, more precisely, ) in a solution. In soils, it is measured in a slurry of soil mixed with water (or a salt solution, such as ), and normally falls between 3 and 10, with 7 being neutral. Acid soils have a pH below 7 and alkaline soils have a pH above 7. Ultra-acidic soils (pH 9) are rare. Soil pH is considered a master variable in soils as it affects many chemical processes. It specifically affects plant nutrient availability by controlling the chemical forms of the different nutrients and influencing the chemical reactions they undergo. The optimum pH range for most plants is between 5.5 and 7.5; however, many plants have adapted to thrive at pH values out ...

Auckland Island
Auckland Island ( mi, Mauka Huka) is the main island of the eponymous uninhabited archipelago in the Pacific Ocean. It is part of the New Zealand subantarctic area. It is inscribed in the UNESCO World Heritage list together with the other New Zealand Subantarctic Islands in the region. Geography The island has a land area of about , and is long. It was formed 25 to 10 million years ago from a huge volcanic pile which formed two domes – one centred around Carnley Harbour in the south and another (the Ross Dome) around Disappointment Island to the west. The island is made of volcanic scoria, blanketed in over 2m of peat. It is notable for its steep cliffs and rugged terrain, which rises to over . Prominent peaks include Cavern Peak, at ; Mount Raynal, at ; Mount D'Urville, at ; Mount Easton, at ; and the Tower of Babel, at . The southern end of the island broadens to a width of , encompassing Carnley Harbour. At the western side a very narrow channel known as Victoria Pas ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
