Wiktionary英語版での「aphotic」の意味 |
aphotic
発音
形容詞
aphotic (comparative more aphotic, superlative most aphotic)
- Having no light, especially no sunlight; specifically (biology, oceanography) describing that part of deep lakes and oceans where less than one per cent of sunlight penetrates and where photosynthesis is not possible.
- 1894 November–December, E. C. Quereau, “Einleitung in die Geologie als historische Wissenschaft. By Johannes Walther. Jena, 1893–4. [book review]”, in The Journal of Geology, volume II, number 8, Chicago, Ill.: University of Chicago Press, ISSN 0022-1376, OCLC 3649177, pages 857–858:
- As experiment has shown that light waves capable of effecting chemical changes do not penetrate the water deeper than 400 meters and as the other conditions of assimilation are met above this line, it is proposed to distinguish a diaphanic region including the land and the water to a depth of 400 m. and inhabited by assimilating organisms and an aphotic region including the ocean and lakes below the assimilation-line and the dark caves of the crust, where plant life is impossible.
- 1894 July 2, Julius Nelson, The Use of Koch’s Lymph in the Diagnosis of Tuberculosis of Cattle (New Jersey Agricultural College Experiment Station Bulletin; 101), [North Brunswick, N.J.: New Jersey Agricultural Experiment Station], OCLC 768020485, § 2 (What is Known about Tuberculosis), page 12:
- 1910 June, Charles Schuchert, “Biologic Principles of Paleogeography”, in J[ames] McKeen Cattell, editor, The Popular Science Monthly, volume LXXVI, New York, N.Y.: The Science Press, OCLC 954266628, page 596:
- Photographically the light of the sun is detectable in exceptionally clear-water tropical seas to a depth of about 2,000 feet, but Johnstone places the average depth for all waters at 650 feet, beyond which there is more or less of total darkness, the aphotic realm.
- 1981, Bruce L. Kimmell, “The Ecological Role(s) of Aquatic Micro-organisms in Lakes and Reservoirs”, in Phillip E. Greeson, editor, Microbiology of the Aquatic Environment (Briefing Papers on Water Quality; Geological Survey Circular; 848-E), [Reston, Va.]: United States Geological Survey, United States Department of the Interior, OCLC 7597204, page E5, column 2:
- Respiration and organic matter decomposition occur through the water column, and depending on the amount of organic matter present and the extent of wind-mixing, can deplete the dissolved oxygen supply in aphotic (unlighted) layers.
- 2003, Andrew S. Cohen, “The Biological Environment of Lakes”, in Paleolimnology: The History and Evolution of Lake Systems, Oxford, Oxfordshire; New York, N.Y.: Oxford University Press, →ISBN, page 96, column 2:
- Although algae are frequently found below the photic zone, because of circulation or settling, they are not photosynthesizing under such conditions. In the aphotic, profundal zone food resources are provided exclusively through secondary productivity, consumption of settling detritus (または the organisms that feed on such detritus), and microbial food resources.
- 2018, Birte Matthiessen; Franziska Julie Werner; Matthias Paulsen, “Ecological Organization of the Sea”, in Markus Salomon and Till Markus, editors, Handbook on Marine Environment Protection: Science, Impacts and Sustainable Management, volume 1, Cham, Switzerland: Springer Nature, DOI: , →ISBN, part I (Nature Science Basics), section 2.3.2 (Aphotic (Dark) Oceanic Benthic Zone), page 53:
- The deep aphotic zone accounts for the largest portion (90%) of the marine benthic environment. Owing to the lack of solar energy, vegetation and photosynthetic primary production are largely nonexistent and food webs are mainly driven by heterotrophy. [...] A special mode of nutrition in the aphotic benthic zone is chemoautotrophy. Here chemoautotrophic bacteria and archaea replace photosynthetic primary production by using geothermally produced inorganic energy as a food source near deep sea vents and cold seeps.
