Abstract: <p>This study was designed to determine the geochemistry and potential toxicity of water draining a large slag pile in Sudbury, Ontario, which runs through a pond complex prior to entering Alice Lake. Slag leaching experiments confirmed slag is a source of sulphate, heavy metals (including Fe, Al, Ni, Co, Cu, Zn, Pb, Cr, Mn) and base cations (Ca, K, Mg, Na). Concentrations of most metals… more

The effects of in-stream woody debris from selective timber harvest on nutrient pools and dynamics within Precambrian Shield streams

Name(s): Creator (cre): Jamieson, Tyler Jacob Ross, Thesis advisor (ths): Watmough, Shaun, Thesis advisor (ths): Eimers, Catherine, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
Abstract: <p>Timber harvest can influence the rate of transfer of organic matter from the terrestrial catchment to streams, which may have both direct and indirect effects on in-stream nutrient pools and dynamics. In the interest of developing sustainable forestry practices, the continued study of the effects of forestry on nutrient dynamics in aquatic systems is paramount, particularly in sensitive… more

The impact of selection harvesting on soil properties and understory vegetation in canopy gaps and skid roads in central Ontario

Name(s): Creator (cre): Treasure, Theresa T., Thesis advisor (ths): Eimers, Catherine, Thesis advisor (ths): Watmough, Shaun, Degree committee member (dgc): Sager, Eric, Degree granting institution (dgg): Trent University
Abstract: <p>Tree harvesting alters nutrient cycling and removes nutrients held in biomass, and as a result nutrient availability may be reduced, particularly in naturally oligotrophic ecosystems. Selection harvesting is a silvicultural technique limited to tolerant hardwood forests where individual or small groups of trees are removed creating a "gap" in the forest canopy. In order for… more
