Phenological
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy for temperature in historical climatology, especially in the stud ...

Charles François Antoine Morren
Charles François Antoine Morren (3 March 1807 in Ghent – 17 December 1858 in Liège), was a Belgian botanist and horticulturist, and Director of the ''Jardin botanique de l'Université de Liège''. Morren is credited with introducing the term "phenology" in 1853. His position at the University of Liege was taken up in 1858 by his son Charles Jacques Édouard Morren. Life and work Morren was born in Ghent and went to study in Brussels where he was a student of Abbé Van Brabant. He also attended the lectures of Adolphe Quetelet at the Athénée, as well as those by Dekin on natural history, Laisné on chemistry, Jean Kickx (1775-1831) and Pierre-Léonard Vander Linden. He taught physics at Ghent University between 1831 and 1835. At the same time he studied medicine and graduated in 1835. He became Professor extraordinarius of botany at the University of Liège from 1835 to 1837, and full professor from 1837 to 1854. Pollination of ''Vanilla'' orchids is required to make th ...

Bird Migration
Bird migration is a seasonal movement of birds between breeding and wintering grounds that occurs twice a year. It is typically from north to south or from south to north. Animal migration, Migration is inherently risky, due to predation and mortality. The Arctic tern holds the long-distance migration record for birds, travelling between Arctic breeding grounds and the Antarctic each year. Some species of Procellariiformes, tubenoses, such as albatrosses, circle the Earth, flying over the southern oceans, while others such as Manx shearwaters migrate between their northern breeding grounds and the southern ocean. Shorter migrations are common, while longer ones are not. The shorter migrations include altitudinal migrations on mountains, including the Andes and Himalayas. The timing of migration seems to be controlled primarily by changes in day length. Migrating birds navigate using celestial cues from the Sun and stars, the Earth's magnetic field, and mental maps.

Biological Life Cycle
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the process repeating in a cyclic fashion. "The concept is closely related to those of the life history, Developmental biology, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For Embryophyte, plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or mor ...

λόγος
''Logos'' (, ; ) is a term used in Western philosophy, psychology and rhetoric, as well as religion (notably Christianity); among its connotations is that of a rational form of discourse that relies on inductive and deductive reasoning. Aristotle first systematized the usage of the word, making it one of the three principles of rhetoric alongside ethos and pathos. This original use identifies the word closely to the structure and content of language or text. Both Plato and Aristotle used the term ''logos'' (along with '' rhema'') to refer to sentences and propositions. Background is related to which is cognate with . The word derives from a Proto-Indo-European root, *leǵ-, which can have the meanings "I put in order, arrange, gather, choose, count, reckon, discern, say, speak". In modern usage, it typically connotes the verbs "account", "measure", "reason" or "discourse".Henry George Liddell and Robert Scott''An Intermediate Greek–English Lexicon'' logos, 1889.Entrat ...

Biography Early years Distant was born in Rotherhithe, the son of whaling captain Alexander Distantspecies:B.R. Subba Rao, Rao, B.R. Subba (1998) ''History of Entomology in India''. Institution of Agricultural Technologists, Bangalore. and his wife, Sarah Ann Distant (née Berry). Following his father's death in 1867, a trip to the Malay Peninsula to visit his older brother, also named Alexander and a ship's captain, aroused his interest in natural history, and resulted in the publication of ''Rhopalocera Malayana'' (1882–1886), a description of the butterflies of the Malay Peninsula. (He considered 5 August 1867 as the most eventful day in his life). Career Much of Distant's early life was spent working in a London tannery, and while employed there he made two long visits to the South African Republic, Transvaal.

The Zoologist
''The Zoologist'' was a monthly natural history magazine established in 1843 by Edward Newman and published in London. Newman acted as editor-in-chief until his death in 1876, when he was succeeded, first by James Edmund Harting (1876–1896), and later by William Lucas Distant (1897–1916). Originating from an enlargement of '' The Entomologist'', ''The Zoologist'' described itself as "an illustrated monthly magazine of natural history", but also as a "journal for recording facts & anecdotes relating to quadrupeds, birds, reptiles, fishes, annelides, insects, worms, zoophytes, &c." and it aimed at describing "their habits, food, retreats, occasional appearance, migrations, nests and young." It contained long articles, short notes, comments on current events, and book reviews covering the entire Animal Kingdom throughout the world, until ''The Entomologist'' was separated again in 1864. Initially, half of the space was devoted to birds, rising to two-thirds later. In 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Academy Of Science, Letters And Fine Arts Of Belgium
The Royal Academy of Science, Letters and Fine Arts of Belgium ( , sometimes referred to as ' ) is the independent learned society of science and arts of the French Community of Belgium. One of Belgium's numerous academies, it is the French-speaking counterpart of the Royal Flemish Academy of Belgium for Science and the Arts. In 2001 both academies founded a joint association for the purpose of promoting science and arts on an international level: The Royal Academies for Science and the Arts of Belgium (RASAB). All three institutions are located in the same building, the Academy Palace in Brussels. History A preexisting literary society was founded in 1769 under the auspices of Karl von Cobenzl, plenipotentiary of the Austrian Netherlands under Empress Maria Theresa (hence its nickname ""). In 1772 Cobenzl's successor Georg Adam, Prince of Starhemberg continued the efforts of his predecessor by expanding the society to a scientific academy. This academy was granted the right ...

Royal Observatory Of Belgium
The Royal Observatory of Belgium (; ; ) has been situated in the Uccle municipality of Brussels since 1890. It is part of the institutions of the Belgian Federal Science Policy Office (BELSPO). The Royal Observatory was first established in Saint-Josse-ten-Noode in 1826 by King William I of the Netherlands under the impulse of the astronomer and mathematician Adolphe Quetelet. It was home to a diameter aperture Zeiss reflector in the first half of the 20th century, one of the largest telescopes in the world at the time. It now owns a variety of other astronomical instruments, such as astrographs, as well as a range of seismograph equipment (for detecting earthquakes). Its main activities are reference systems and geodynamics, astrometry and dynamics of celestial bodies, astrophysics, and Solar physics. The asteroid 1276 Ucclia is named in honour of the city and the observatory and 16908 Groeselenberg is named for the hill the observatory is located on. History 19th cent ...
