Viola Lutea
''Viola lutea'', the mountain pansy, is a species of violet that grows in Europe, from the British Isles to the Balkans. Description ''Viola lutea'' grows to a height of around . Its flowers are in diameter, and are typically yellow, although some individuals may have blue, purple or blotched flowers instead. Taxonomy ''Viola lutea'' was first described by William Hudson in his 1762 '' Flora Anglica''. ''V. lutea'' subsp. ''lutea'' is native to central and north-western Europe, from the British Isles to Austria; another subspecies occurs further east, from Hungary to the Balkans. Two very special subspecies are ''V. lutea'' subsp. ''calaminaria'' which occurs in the southernmost Netherlands and eastern Belgium, and ''V. lutea'' subsp. ''westfalica'', which only occurs at an extremely small locality near in East Westphalia, Germany. Both taxa have relatively recently evolved to take advantage of the local pollution left over after centuries of mining for metals in these ...

William Hudson (botanist)
William Hudson Fellow of the Royal Society, FRS (1730 in Kendal – 23 May 1793) was a British botanist and apothecary based in London. His main work was ''Flora Anglica'', published in 1762. He was elected a fellow of the Royal Society in 1761. Life and work Hudson was born between 1730 and 1732 at the White Lion Inn, Kendal, which was kept by his father. He was educated at Kirkbie Kendal School, Kendal grammar school, Hudson was subsequently apprenticed to an apothecary in London. He obtained the prize for botany given by the Apothecaries' Company which was a copy of John Ray, Ray's ''Synopsis''. However, he also paid attention to mollusca and insects and in Thomas Pennant, Pennant's ''British Zoology'' he is mentioned as the discoverer of ''Trochus terrestris''. From 1757 to 1768 Hudson was resident sub-librarian of the British Museum, and his studies in the Chelsea Physic Garden, Sloane herbarium enabled him to adapt the Linnean nomenclature to the plants described by Ray ...

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Biological Records Centre
The Biological Records Centre (BRC) established in 1964, is a national focus in the UK for terrestrial and fresh water species recording. The term "biological records centre" is also used in the context of local centres, now frequently referred to as "local environmental records centres" (LERCs). History The Biological Records Centre (BRC) was set up in 1964 by the Nature Conservancy (UK) at its recently opened Monks Wood Experimental Station near Huntingdon. BRC developed from the Atlas of the British Flora project of the Botanical Society of the British Isles (BSBI) to map the distribution of British (and Irish) flowering plants, which had established basic principles for biological recording in the UK. The former BSBI project leader, Franklyn Perring, established BRC with the project's original data and data processing equipment. Function As part of the UK Centre for Ecology & Hydrology (UKCEH), BRC provides a focus for the collation, management, dissemination and interp ...

Pansy
The garden pansy (''Viola'' × ''wittrockiana'') is a type of large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from several species in the section ''Melanium'' ("the pansies") of the genus ''Viola'', particularly '' Viola tricolor'', a wildflower of Europe and western Asia known as heartsease. It is sometimes known as ''Viola tricolor'' var. ''hortensis'', but this scientific name is ambiguous. While ''Viola tricolor'' var. ''hortensis'' Groenland & Rümpler is a synonym of ''Viola'' × ''wittrockiana'', ''Viola tricolor'' var. ''hortensis'' DC. refers to a horticultural variety of wild pansy ('' Viola tricolor'' without interspecific hybridization) that had been illustrated in '' Flora Danica'' in 1777 before the existence of ''Viola'' × ''wittrockiana''. The chromosome number of ''Viola'' × ''wittrockiana'' is 2n = 44–52, with most cultivars being 2n = 48. The flower is in diameter and has two slightly overlapping upper peta ...

Wicklow Mountains
The Wicklow Mountains (, archaic: '' Cualu'') form the largest continuous upland area in the Republic of Ireland. They occupy the whole centre of County Wicklow and stretch outside its borders into the counties of Dublin, Wexford and Carlow. Where the mountains extend into County Dublin, they are known locally as the Dublin Mountains (''Sléibhte Bhaile Átha Cliath''). The highest peak is Lugnaquilla at . The mountains are primarily composed of granite surrounded by an envelope of mica-schist and much older rocks such as quartzite. They were pushed up during the Caledonian orogeny at the start of the Devonian period and form part of the Leinster Chain, the largest continuous area of granite in Ireland and Britain. The mountains owe much of their present topography to the effects of the last ice age, which deepened the valleys and created corrie and ribbon lakes. Copper and lead have been the main metals mined in the mountains and a brief gold rush occurred in the 18th centur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
