Mixtures of metals and polycyclic aromatic hydrocarbons (PAHs) occur ubiquitously in aquatic environments, yet relatively little is known regarding their potential to produce non-additive toxicity (i.e., antagonism or potentiation). A review of the l

Questions: Understanding factors that contribute to the stability of an ecosystem following harvesting is central to predicting responses of boreal ecosystems toincreasing human disturbances.While the responseofunderstorey vegetation to harvesting is

Northern pike (Esox lucius) are often considered to be specialist piscivores, but under some circumstances will continue to eat invertebrates as adults. To examine effects of fish assemblage composition on the trophic ecology of pike, we combined sta

Management of riparian forests, and how they respond to disturbance, continues to be a focus of interest in the literature. Earlier studies on riparian plant community assembly following harvesting in the boreal forest have focused merely on highly c

Streamflow in small forested watersheds on the Boreal Plain of western Canada can be a challenge to monitor due to high variation in flow, shifting channel morphology, aufeis obstructions, shallow channel depth, and debris in the channel. Intensive m

Refugia likely represent a critical resource necessary for the persistence of populations of Boreal Toads (Anaxyrus boreas boreas (Baird and Girard, 1852)) in a given area. However, the features that define suitable refuge microsites and the extent t

Vegetation biomass is the ideal variable to estimate vegetation abundance and productivity and is necessary for studies of community structure. However, biomass data are difficult and destructive to collect, unlike areal cover data. To date, equation

Nitrate, ammonium, total dissolved nitrogen (TDN), dissolved organic nitrogen (DON) and dissolved organic carbon (DOC) concentrations and flux were measured for one year in bulk deposition and throughfall from three stand types (upland deciduous, upl

Euphotic water samples were collected monthly from 16 sites in Lake of the Woods, Ontario, Canada from July to September, 2006 and 2007. Sites represented a range of inorganic nitrogen and phosphorus concentrations and mixing regimes, which was refle

Increased release of nitrogen to hydrological networks due to watershed disturbance may cause aquatic problems and affect water uses. Therefore, effective nitrogen modelling is an important element of total watershed management. The objective of this
