Abstract Our present understanding of the effects of natural and anthropogenic disturbances on aquatic systems in forested landscapes is based on a long history of studies relating physical, chemical and biological variables to biotic responses. The explanatory relationships resulting from this work have proven informative for ensuring environmentally-sound forest management, but such evaluations have not been applied to all forest types and management conditions and rarely in the context of aqu...

Much of Canada's industrial sector is driven by natural resources and relies heavily on provisioning services supplied by the boreal zone. However, the sometimes intensive processes used by resource-based industries and their associated infrastructure have significantly altered the region, creating concerns over the future socio-ecological health of the boreal zone. Addressing these concerns will require industries reliant on natural resources from the boreal zone to innovate their processes, ma...

Abstract Aquatic macroinvertebrate communities are often used to assess the ecological integrity of streams. However, conventional methods involving morphometric identification of macroinvertebrates are usually costly and time-consuming. Here we compare stream macroinvertebrate community metrics based on conventional morphometrics vs . non-destructive DNA metabarcoding from storage ethanol to assess forest management impacts on headwater streams across a gradient of intensively managed forest ca...

Receiving waters from agricultural areas can contain multiple pesticides such as the neonicotinoid imidacloprid and the fungicide tebuconazole, leading to the potential for aquatic life to be exposed to such mixtures. In the present study, the effects of tebuconazole were tested alone and in binary mixtures with imidacloprid on 4 aquatic invertebrates: Chironomus dilutus, Hyalella azteca, Lumbriculus variegatus, and Neocloeon triangulifer. Acute (96‐h) median lethal concentrations (LC50s) were d...

Forested headwater streams are strongly connected to their surrounding riparian areas via the transfer of energy subsidies that underpin instream food webs and, therefore, are highly sensitive to riparian disturbances that influence allochthonous inputs. We compared terrestrial and aquatic invertebrates found in drift across headwater streams in boreal forested catchments with wildfire, harvest with minimum 30-m riparian buffers, and reference catchment histories. Fire-disturbed streams containe...

Rapid loss of ash (Fraxinus spp.) trees in riparian forests from an invasive insect, the emerald ash borer (EAB; Agrilus planipennis Fairmaire, 1888), could pose risk of altering organic matter inputs to water bodies that underpin many aquatic ecosystem processes. We measured the composition of riparian forests and their leaf-litter contributions to headwater streams and determined the relative palatability of ash leaves and leaves of three other common riparian trees to aquatic invertebrate lea...

Abstract Neonicotinoid insecticides are a group of plant protectants frequently detected in surface waters at low concentrations. Aquatic invertebrates therefore have the potential to be exposed chronically to low concentrations of neonicotinoids. The cladocerans Daphnia magna and Ceriodaphnia dubia are among the most commonly used invertebrate test species in aquatic toxicology. Both species are known to be acutely insensitive to neonicotinoids, and while chronic toxicity has been characterized...

Abstract The implementation of ecologically relevant sub-lethal endpoints in toxicity testing with freshwater mussels can provide valuable information during risk assessment, especially since these organisms are often exposed to low levels of contaminants. This study examined how to optimize quantifying the filtering capacity or clearance rate (CR) of mussels after exposure to a reference toxicant, sodium chloride (NaCl). CR was defined as the number of algal cells an individual mussel can remov...
