Nitrogen and phosphorous budgets in a lacustrine sand dune ecosystem

Adventitious Root Production and Plastic Resource Allocation to Biomass Determine Burial Tolerance in Woody Plants from Central Canadian Coastal Dunes

“…Mean daily temperature of the coldest month (January) is -5Á4 C, and that of the warmest month (July) is 20Á9 C. Mean annual precipitation is 847 mm (Environment Canada, 2006a). Soils in this habitat are poorly developed from lacustrine sand parent materials (>97 % sand), are well drained and have low silt and clay content, low organic matter (<2 %), low levels of nitrogen and phosphorus, neutral pH and high calcium carbonate content (VandenBygaart and Protz, 1995;Maun and Sun, 2002). An experimental site was established on the gentle windward slope of the second dune ridge, and it was fenced to exclude park visitors.…”

Coastal Dunes

“…;Vázquez, Chap. In addition, the increased atmospheric input of nitrogen, because of industrialization, automobile combustion, and increasing population size may accelerate the successional pathway (Maun and Sun 2002;Kooijman, Chap. There is evidence that the rate of vegetation succession is largely controlled by the productivity of the ecosystem, the decomposition of organic matter, and the recycling of nutrients within the ecosystem .…”
