... Numerous more recent reports showed that several herbaceous and woody plant species tended to close their stomata in response to dry air whether within a plant community or in attached leaves or isolated epidermal strips (e.g. Hoffman and Rawlins 1971, Hoffman et al. 1971, Lange et al. 1971, Schulze et al. 1972, Aston 1976, Hall and Hoffman 1976, Rawson et al. 1977, Sheriff and Kaye 1977, Lösch 1977, 1979, Lösch and Schenk 1978, Tibbitts 1979, Ludlow and Ibaraki 1979, Lösch and Tenhunen 1981, Farquhar et al. 1980, Jarvis 1980, Tazaki et al. 1980, Hall and Schulze 1980, Bunce 1981, 1982, 1984, Leverenz 1981, Fanjul and Jones 1982, Meinzer 1982, Kaufmann 1982, Schulze and Hall 1982, Gollan et al. 1985, Körner 1985, Körner and Bannister 1985, Schulze 1986, Jarvis and McNaughton 1986, Ward and Bunce 1986, Bongi et al. 1987, Hirasawa et al. 1988, Pettigrew et al. 1990, Held 1991, Kappen and Haeger 1991, Tinoco-Ojanguren and Pearcy 1993). This apparently widespread phenomenon indicated the need for further detailed studies, and for its inclusion in plant community/environment ecosystem models (Jarvis and McNaughton 1986). ...
