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 ...

Historical Climatology
Historical climatology is the study of historical changes in climate and their effect on civilization from the emergence of homininis to the present day. This differs from paleoclimatology which encompasses climate change over the entire history of Earth. These historical impacts of climate change can improve human life and cause societies to flourish, or can be instrumental in civilization's societal collapse. The study seeks to define periods in human history where temperature or precipitation varied from what is observed in the present day. The primary sources include written records such as sagas, chronicles, maps and local history literature as well as pictorial representations such as paintings, drawings and even rock art. The archaeological record is equally important in establishing evidence of settlement, water and land usage. Techniques In literate societies, historians may find written evidence of climatic variations over hundreds or thousands of years, such as phen ...

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 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. Morren discovered that the vanilla flower is pollinated by the social and stingless Melipone bee, which occurs only in Mexico, obviating natural pollination in other countries. Hernán Cortés brought vanilla to Europe, but for more than 300 years the pollination mechanism remained a mystery. Morren was the first to discover a method for artificial pollination, which made it possible to cultivate vanilla in the French colonies. Pollination of vanilla pods is required to make the plants produce the fruit from which the v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Life Cycle
In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, 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 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 more), rather than two.Dixon, P.S. 1973. ''Biology of the Rhodophyta.'' Oliver & Boyd. Life cycles that include sexual reproduction involve alternating haploid (''n'') and diploid (2''n'') stages, i.e., a change of ...

William Lucas Distant
William Lucas Distant (12 November 1845 Rotherhithe – 4 February 1922 Wanstead) was an English entomologist. Biography Early years Distant was born in Rotherhithe, the son of whaling captain Alexander Distant 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 Transvaal. The first resulted in the publication of ''A Naturalist in the Transvaal'' (1892). The second v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
