Studies in Europe have reported negative effects of acid deposition on forest birds, and research in North America has identified links between forest bird abundance and rates of acid deposition. We examined the bird community in an acidified forest in central Pennsylvania (USA) and evaluated the effects of terrestrial lime application on birds. We used a before-after control-impact (BACI) stud...

18 Understanding the regulation of calcium uptake, xylem transport and its impacts on growth and leaf 19 gas exchange is a subject that has received insufficient recent attention. Calcium (Ca) is unique 20 within the group of key elements required for plant growth in that it also has a role in cellular 21 signalling via regulation of changes in its cytoplasmic concentration. Its mobility, withi...

Previous research had identified four serogroups of Rhizobium trifolii indigenous to the acidic Abiqua soil (fine, mixed, mesic Cumulic Ultic Haploxeroll). Nodulation of subterranean clover (Trifolium subterraneum L.) by two of the serogroups, 6 and 36, was differentially influenced by an application of CaCO(3) which raised the pH of the soil from 5.0 to 6.5. These studies were designed to char...

ÐChanges in land use and management of tropical systems are considered to be major factors in the recent upsurge in increases in atmospheric nitrous oxide (N2O) and methane (CH4). Studies were initiated in western Puerto Rico grasslands to determine the e€ect of plowing, or liming and fertilizing an acid Oxisol on the soil±atmosphere exchanges of N2O and CH4. Weekly ®eld ̄ux measurements and ®el...

Tests have been conducted to determine the effect of liming and magnesium treatment on the content of magnesium, calcium and iron in broad bean plants growing on soil polluted with such heavy metals as cadmium, lead, nickel, copper and zinc. In 2005, an experiment was conducted in the village Zagaje Stradowskie (Œwiêtokrzyskie Province) on degraded Chernozem formed from loess, acid in reaction ...
