Red spruce ecosystem level changes following 14 years of chronic N fertilization
In the early 1980s, nitrogen (N) deposition was first postulated as a cause of N saturation and spruce mortality across the northeastern US. In 1988, a series of high elevation spruce-fir forest N addition plots were established on Mt. Ascutney (southeastern) Vermont to test this hypothesis. The paired plots each received, in addition to ambient N deposition, 15.7 kg N ha-' (low N addition), 31...
متن کاملEffects of chronic low-level N additions on foliar elemental concentrations, morphology, and gas exchange of mature montane red spruce
We evaluated the influence of protracted low-level nitrogen (N) fertilization on 29 morphological, physiological, or chemical parameters measured on mature red spruce (Picea rubens Sarg.) growing within 10 study plots on Mount Ascutney, Vermont. For 8 consecutive years prior to this study, each plot received one of five treatments: 0, 15.7, 19.8,25.6, or 3 1.4 kg N.ha-‘.year@. In comparison to ...
متن کاملRoot length, biomass, tissue chemistry and mycorrhizal colonization following 14 years of CO2 enrichment and 6 years of N fertilization in a warm temperate forest.
Root systems serve important roles in carbon (C) storage and resource acquisition required for the increased photosynthesis expected in CO2-enriched atmospheres. For these reasons, understanding the changes in size, distribution and tissue chemistry of roots is central to predicting the ability of forests to capture anthropogenic CO2. We sampled 8000 cm(3) soil monoliths in a pine forest expose...

متن کاملGap Dynamics following Forest Decline: a Case Study of Red Spruce Forests
Forest decline is perceived as a threat to forest health in many regions of the world. The decline of red spruce in the mountains of the northeastern United States is one well-known example. We evaluated the impact of spruce decline by considering its effect on the prevailing gap dynamics. We compared plant composition, height growth, and indices of resource availability in gaps to the forest a...
