(Elsevier, 1985-03)
Fungal community composition and metabolism under elevated CO 2 and O 3
(Springer-Verlag, 2006-02)
Atmospheric CO 2 and O 3 concentrations are increasing due to human activity and both trace gases have the potential to alter C cycling in forest ecosystems. Because soil microorganisms depend on plant litter as a source ...
Coastal eutrophication assessment in the United States

Recent national assessments document that nitrogen-driven coastal eutrophication is widespread and increasing in the United States. This significant coastal pollution problem includes impacts including increased areas and ...
Effects of host switching on gypsy moth ( Lymantria dispar (L.)) under field conditions
(Springer-Verlag, 1994-03)
Effects of various single and two species diets on the performance of gypsy moth ( Lymantria dispar (L.)) were studied when this insect was reared from hatch to population on intact host trees in the field. The tree species ...
Nitrate deposition in northern hardwood forests and the nitrogen metabolism of Acer saccharum marsh
(Springer-Verlag, 1996-10)
It is generally assumed that plant assimilation constitutes the major sink for anthropogenic Nitrate NO 3 − deposited in temperate forests because plant growth is usually limited by nitrogen (N) availability. Nevertheless, ...
Models of coupled population oscillators using 1-D maps
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-08)
Coupled population oscillators are investigated with the use of coupled logistic maps. Two forms of coupling are employed, reproductive and density. Three biologically distinct situations are investigated: populations ...

Impacts of major predators on tropical agroforest arthropods: comparisons within and across taxa
(Springer-Verlag, 2004-06)
In food web studies, taxonomically unrelated predators are often grouped into trophic levels regardless of their relative importance on prey assemblages, multiple predator effects, or interactions such as omnivory. Ants ...
