Allan Green (botanist)
Thomas George Allan Green is a lichenologist, terrestrial ecologist and botanist. He is a professor emeritus at the University of Waikato, Hamilton, New Zealand. His work particularly studies how lichens respond to extreme low temperatures and dryness, and especially how this affects photosynthesis. He has studied the ecology of Antarctica. Early life and education Green was born in the United Kingdom and studied lichens for his PhD at University of Oxford that was awarded in 1970. His supervisor was David Cecil Smith. Career Green moved to University of Waikato in 1974, and has continued to work there throughout his career. By 2022 he held an emeritus professor position. He has long-standing collaborations in Spain and Germany, and he also works with scientists at research stations in Antarctica. His research focuses on the physiology of lichens and especially how they respond to their environment, particularly extreme dry and cold environments. He has made extensive studie ...

Lichenology
Lichenology is the branch of mycology that studies the lichens, symbiotic organisms made up of an intimate symbiotic association of a microscopic alga (or a cyanobacterium) with a filamentous fungus. Study of lichens draws knowledge from several disciplines: mycology, phycology, microbiology and botany. Scholars of lichenology are known as lichenologists. History The beginnings Lichens as a group have received less attention in classical treatises on botany than other groups although the relationship between humans and some species has been documented from early times. Several species have appeared in the works of Dioscorides, Pliny the Elder and Theophrastus although the studies are not very deep. During the first centuries of the modern age they were usually put forward as examples of spontaneous generation and their reproductive mechanisms were totally ignored. For centuries naturalists had included lichens in diverse groups until in the early 18th century a French researche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2013 Birthday Honours (New Zealand)
The 2013 Queen's Birthday Honours in New Zealand, celebrating the official birthday of Queen Elizabeth II, were appointments made by the Queen in her right as Queen of New Zealand, on the advice of the New Zealand government, to various orders and honours to reward and highlight good works by New Zealanders. They were announced on 3 June 2013. The recipients of honours are displayed here as they were styled before their new honour.

Plant Ecologists
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Alumni Of The Queen's College, Oxford
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Association For Lichenology
The International Association for Lichenology (IAL) is an organisation that encourages the understanding of lichens and lichenology, and promotes their study and conservation worldwide. It unites lichenologists across the globe, as well as national and regional organisations into one group. It is affiliated to the International Union of Biological Sciences (IUBS). The IAL organises field courses and excursions, as well as symposia which are the biggest events in lichenology on the international level. The 8th International Symposium will be held in Helsinki, Finland, in August 2016. The IAL publishes a biennial journal, the International Lichenological Newsletter which was the raison d'etre for the IAL being formed in 1967 in order to provide a forum for lichenologists worldwide to communicate with one other. Nowadays the IAL also operates an online discussion forum for lichenologists known as 'lichens-L'. History The International Lichenological Association arose out of the 10th I ...

New Zealand Antarctic Medal
The New Zealand Antarctic Medal was created 1 September 2006, as a New Zealand royal honour to replace the British Polar Medal. History The Polar Medal was instituted in 1904 and awarded to those who had made notable contributions to the exploration and knowledge of polar regions and who, in doing so, had undergone the hazards and rigors imposed by the polar environment to life and movement, whether by land, sea or air. In 1995, the Prime Minister’s Honours Advisory Committee recommended that the Polar Medal should be created under a New Zealand royal warrant. It also recommended that it should be renamed as “The Antarctic Medal” to reflect the fact that it is in relation to Antarctica that New Zealand’s endeavors and achievements have been made. The New Zealand Antarctic Medal was formally instituted by Queen Elizabeth II on 1 September 2006. Eligibility The New Zealand Antarctic Medal may be awarded to those New Zealanders and other persons who either individually o ...

Biological Carbon Fixation
Biological carbon fixation or сarbon assimilation is the process by which inorganic carbon (particularly in the form of carbon dioxide) is converted to organic compounds by living organisms. The compounds are then used to store energy and as structure for other biomolecules. Carbon is primarily fixed through photosynthesis, but some organisms use a process called chemosynthesis in the absence of sunlight. Organisms that grow by fixing carbon are called autotrophs, which include photoautotrophs (which use sunlight), and lithoautotrophs (which use inorganic oxidation). Heterotrophs are not themselves capable of carbon fixation but are able to grow by consuming the carbon fixed by autotrophs or other heterotrophs. "Fixed carbon", "reduced carbon", and "organic carbon" may all be used interchangeably to refer to various organic compounds. Chemosynthesis is carbon fixation driven by chemical energy, rather than from sunlight. Sulfur- and hydrogen-oxidizing bacteria often use th ...
