Mary Gibby
Professor Mary Gibby (27 February 1949 – 17 July 2024) was a British botanist, pteridologist and cytology, cytologist. She was an expert on ferns, becoming president of the British Pteridological Society and long-time editor of its journal, the ''Fern Gazette''. Gibby particularly studied the cytology of the genera ''Dryopteris'' and ''Pelargonium''. Early life and education Gibby was born on 27 February 1949 in Doncaster, South Yorkshire, to Edgar and Sheila Ambrose (née Bickerton). Her father was a teacher and the family moved to Greysouthen when she was a child. Gibby studied botany at the University of Leeds under Irene Manton and John Lovis, graduating with a first-class degree in 1971. During her undergraduate studies, she spent a summer as an intern at the Natural History Museum, London (NHM). She went on to study for a PhD on biosystematics and cytogenetics of the genus ''Dryopteris'' at the University of Liverpool under Stanley Walker. Career In 1975, during the com ...

Botany
Botany, also called plant science, is the branch of natural science and biology studying plants, especially Plant anatomy, their anatomy, Plant taxonomy, taxonomy, and Plant ecology, ecology. A botanist or plant scientist is a scientist who specialises in this field. "Plant" and "botany" may be defined more narrowly to include only land plants and their study, which is also known as phytology. Phytologists or botanists (in the strict sense) study approximately 410,000 species of Embryophyte, land plants, including some 391,000 species of vascular plants (of which approximately 369,000 are flowering plants) and approximately 20,000 bryophytes. Botany originated as history of herbalism#Prehistory, prehistoric herbalism to identify and later cultivate plants that were edible, poisonous, and medicinal, making it one of the first endeavours of human investigation. Medieval physic gardens, often attached to Monastery, monasteries, contained plants possibly having medicinal benefit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biosystematics
Systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships, graphically represented in cladograms) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word of Ancient Greek origin '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branch ...

Plant Conservation
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management. The nature conservation, conservation ethic is based on the findings of conservation biology. Origins The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American biologists Bruce A. Wilcox and Michael E. Soulé with a group of leading university and zoo researchers and conservationists including Kurt Benirschke, Sir Otto Frankel, Thomas Lovejoy, and Jared Diamond. The meeting was prompted due to concern over tropical de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Guardian
''The Guardian'' is a British daily newspaper. It was founded in Manchester in 1821 as ''The Manchester Guardian'' and changed its name in 1959, followed by a move to London. Along with its sister paper, ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust Limited. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in its journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chloroplast DNA
Chloroplast DNA (cpDNA), also known as plastid DNA (ptDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and '' Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, tens of thousands of chloroplast genomes from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gel Electrophoresis
Gel electrophoresis is an electrophoresis method for separation and analysis of biomacromolecules (DNA, RNA, proteins, etc.) and their fragments, based on their size and charge through a gel. It is used in clinical chemistry to separate proteins by charge or size (IEF agarose, essentially size independent) and in biochemistry and molecular biology to separate a mixed population of DNA and RNA fragments by length, to estimate the size of DNA and RNA fragments, or to separate proteins by charge. Nucleic acid molecules are separated by applying an electric field to move the negatively charged molecules through a gel matrix of agarose, polyacrylamide, or other substances. Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving. Proteins are separated by the charge in agarose because the pores of the gel are too large to sieve proteins. Gel electrophoresi ...

Asplenium
''Asplenium'' is a genus of about 700 species of ferns, often treated as the only genus in the family (biology), family Aspleniaceae, though other authors consider ''Hymenasplenium'' separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is ''Asplenium marinum''. The most common vernacular name is spleenworts, applied to the more "typical" species. ''Asplenium nidus, A. nidus'' and several similar species are called bird's-nest ferns, the ''Camptosorus'' group is known as walking ferns, and distinct names are applied to some other particularly well-known species. Etymology From Neo-Latin, New Latin ''asplenium'' (“spleenworts”), Carolus Linnaeus, Linnaeus's adjustment of Latin ''asplenon'' (“spleenwort”), from Ancient Greek ἄσπληνον (''ásplēnon'', “spleenwort”), from ἀ- (''a-'', “un-”) + σπλήν (''splḗn'', “spleen”) + -ο� ...

Macaronesian
Macaronesia (; ) is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coast of North Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which were formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface. Each of the archipelagos is a distinct political entity: the Azores and Madeira are autonomous regions of Portugal, the Canary Islands is an autonomous community of Spain, while Cape Verde is a sovereign state and member of the United Nations. Politically, the islands belonging to Portugal and Spain are parts of the European Union, while Cape Verde is a member of the African Union. Geologically, most of Macaronesia is part of the African tectonic plate. The Azores are located in the triple junction between the Eurasian, African, and North American plates. In one biogeographical system, the Cape Verde archipelago is in the Afrotropical realm while the other three archipel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichomanes Speciosum
''Vandenboschia speciosa'', synonym ''Trichomanes speciosum'', commonly known as the Killarney fern, is a species of fern found widely in Western Europe. It is most abundant in Ireland, Great Britain, Brittany, Galicia, Canary Islands, Madeira and the Azores, but is also found in other locations including France, Spain, Portugal and Italy. It is a relict endemic European species with a disjunct distribution, having had a much wider distribution before the climate changes of the Tertiary and Quaternary periods. This fern has an unusual life cycle, with a perennial gametophyte phase with an active vegetative reproduction. The gametophyte has the ability to tolerate darker and drier habitats than does the sporophyte. The sporophyte form is found in only 16 locations in the UK although the gametophyte form is more widespread. Once found on Arran, it was thought to be extinct in Scotland due to the activities of Victorian collectors, but the species has been discovered on Skye ...
