Below-ground responses of silver birch trees exposed to elevated CO2 and O-3 levels during three growing seasons (2005)

Kasurinen, A, Keinanen, MM, Kaipainen, S, Nilsson, LO, Vapaavuori, E, Kontro, MH, ...

Field-growing silver birch (Betula pendula Roth) clones (clone 4 and 80) were exposed to elevated CO2 and O-3 in open-top chambers for three consecutive growing seasons (1999-2001). At the beginning...

Transplanted lichens as biomonitors for atmospheric fluoride pollution near two fluoride point sources in Flanders (Belgium) (2005)

Responses of Leaf Processes in a Sensitive Birch (Betula pendulaRoth) Clone to Ozone Combined with Drought (1998)

PÄÄKKÖNEN, E., GÜNTHARDT-GOERG, M. S., HOLOPAINEN, T.

Saplings of an ozone sensitive clone of birch (Betula pendulaRoth, KL-5-M) were well-watered or exposed to mild drought-stress combined with ambient or elevated (1.5×the ambient) ozone for 11 weeks...

Ultrastructural Changes and Electrolyte Leakage from Ozone Fumigated Epiphytic Lichens (1997)

TARHANEN, S., HOLOPAINEN, T., OKSANEN, J.

The ultrastructure of lichens and leakage of electrolytes from them were studied to assess the effects of ozone on four epiphytes.Bryoria capillaris(Ach.) Brodo & Hawksw.,Bryoria fuscescens(Gyelnik)...

Ageing-related Anatomical and Ultrastructural Changes in Leaves of Birch (Betula pendula Roth.) Clones as Affected by Low Ozone Exposure (1995)

Pääkkönen, E., Holopainen, T., Kärenlampi, L.

Effects of ozone on the leaf anatomy and ultrastructure of five birch (Betula pendula Roth.) clones were studied during one growing season in open-field conditions. Cumulative ozone exposure was 1·5...
