Pleistocene glacial cycles influenced the diversification of high-latitude wildlife species through recurrent periods of range contraction, isolation, divergence, and expansion...

Continuous ambient air analyzers require multipoint calibrations on a routine monthly basis and after major maintenance is completed. This procedure describes the role of Zero-...

Compressed gas cylinders are used in a variety of applications involved with ambient air monitoring. Safe handling of these cylinders is required for all concerned. This...

This is the first annual technical report from the multistakeholder WaterSHED water quality monitoring program of North Saskatchewan River Basin tributaries. The report includes...

Integrating soil physico-chemical properties and soil invertebrate bioindicators could prove a practical and robust method for assessing reclamation and soil biological quality...

•δ2H and δ18O were measured bi-weekly during ice-free season for 14 years in 7 lakes. •Variation was greater among seasons than years in lakes with residence time < 1 year....

Highlights •The source dynamics of total and dissolved material were investigated. •Water quality monitoring data was modelled with Deconvolutional-MixSIAR. •A novel approach to...

Canada's federal recovery strategy for boreal woodland caribou (Rangifer tarandus caribou) classifies areas burned by forest fire as disturbed habitat. This assignment of fire...

Changes in primary productivity have the potential to substantially alter food webs, with positive outcomes for some species and negative outcomes for others. Understanding the...

As global climate change progresses, wildlife management will benefit from knowledge of demographic responses to climatic variation, particularly for species already endangered...

Accurately estimating abundance is a critical component of monitoring and recovery of rare and elusive species. Spatial capture–recapture (SCR) models are an increasingly...

Endangered species policies and their associated recovery documents and management actions do not always sufficiently address the importance of migratory behaviour and seasonal...

Habitat loss is often the ultimate cause of species endangerment and is also a leading factor inhibiting species recovery. For this reason, species-at-risk legislation, policies...

Walleye (Sander vitreus) populations in Alberta, Canada, collapsed by the mid-1990s and were a case study in the paper Canada’s Recreational Fisheries: The Invisible Collapse?...

Myxobolus cerebralis is the parasite causing whirling disease, which has dramatic ecological impacts due to its potential to cause high mortality in salmonids. The large-scale...

Polycyclic aromatic compounds (PACs) threaten the health of aquatic ecosystems. In northeastern Alberta, Canada, decades of oil sands mining and upgrading activities have...

This report presents the methods used to generate the web-based Condition on Environment (CoE) content published for chloride (Cl-) concentrations in the surface water of major...

Highlights • New geospatial method to optimize water monitoring programs or design new networks. • Catchment Structural Units (CSU) quantify key landuse/landcover, geology,...

Abstract: Salinization is increasingly recognized as a global issue. However, the relative importance of different drivers across a broad range of ions and ecosystems is not...

This Alberta Environment and Parks (AEP) lotic quality control report investigates the bias and variability of data generated from the Long Term River Network (LTRN) and...
