Aqueous ammonium nitrate (NH4NO3) was applied above the forest canopy across five treatment plots (20 x 80 m) four times… more Full Text: Ecosystem Response to Above Canopy Nitrogen Addition in a Jack Pine (Pinus banksiana) Forest in the Athabasca Bituminous Sands Region of Northeastern Alberta, Canada A Thesis Submitted to the Committee on Graduate Studies in the Partial Fulfilment of the …

Abstract: <p>Decades of acidic deposition have depleted base cation pools in soil over large parts of eastern north America, including the Muskoka-Haliburton region of central Ontario. This region has also experienced a shift in forest species composition over the past 200 years, favouring sugar maple (Acer saccharum Marsh.) at the expense of species such as white pine (Pinus strobus L.) and eastern… more Full Text: The influence of tree species litterfall on soil chemistry and implications for modelling soil recovery from acidification A thesis submitted to the Committee of Graduate Studies in partial fulfillment of the requirements for the degree of Master of …
