PROFESSIONAL PUBLICATIONS... OF GENERAL INTEREST: IMPACTS
Effects on Mountain Plants," G. Grabherr (Dept. Vegetation
Ecol., Univ. Vienna, POB 285, A1091 Vienna, Austria), M.
Gottfried, H. Pauli, Nature, 369(6480), 448, June
Compares results of a recent survey of cover and abundance of
vascular plant species above 3,000 meters in the central Alps
with historical data. There is no doubt that even moderate
warming induces upward migration, and that this process is
underway; results suggest that global warming is already having a
significant effect on alpine plant ecology.
Possible Mechanism Relating Increased Soil Temperature to Forest
Decline," G.H. Tomlinson (920 Perrot Blvd., Ile-Perrot PQ
J7V 3K1, Can.), Water, Air & Soil Pollut., 66,
Leaching of nutrient cations in soils by acid deposition is
associated with periods of increased temperature and reduced
rainfall. This paper discusses the relevance of earlier studies
on the influence of temperature, when considered in relation to
more recent findings such as the impacts of increased temperature
and drought in Hawaii resulting from the El Niño/Southern
Oscillation. The unusual periods of increased temperature and
drought that have occurred in other localized areas may have led
to the decline symptoms recently observed; this possibility
should be investigated in view of the threat of global warming.
