Giuseppe De Notaris the University of Rome. In the field of mycology, he proposed the fungi family Hypocreaceae (1845). With Antonio Bey Figari (1804-1870), he described numerous species from the family Poaceae. With Figari, he was the binomial co-author of the grass genus "Schistachne" (synonym "Stipagrostis"). Organisms with the specific epithet of "notarisiana" commemorate his name. Giuseppe De Notaris Giuseppe De Notaris (18 April 1805, Milan – 22 January 1877) was an Italian botanist generally known for his work with cryptogams native to Italy. He studied medicine at the University of Pavia, obtaining his medical degree in 1830. Having developed an interest in
Organisms at high altitude the tree line. The highest-altitude plant species is a moss that grows at on Mount Everest. "Arenaria bryophylla" is the highest flowering plant in the world, occurring as high as . Organisms at high altitude Organisms can live at high altitude, either on land, in water, or while flying. Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes. As opposed to short-term acclimatisation (immediate physiological response to changing environment), high-altitude adaptation means irreversible, evolved physiological responses to high-altitude environments, associated with heritable behavioural and genetic changes.
