Chronic bioaccumulation and toxicity of cadmium from a periphyton diet to Hyalella azteca
(University of Waterloo, 2010-06-18)Dietary cadmium (Cd) can contribute significantly to chronic bioaccumulation and toxicity in aquatic organisms. This contribution needs to be quantified so that the relative importance of waterborne and dietary cadmium ... -
Chronic Nickel and Copper Toxicity in the Hyalella azteca Cryptic Species Complex
(University of Waterloo, 2016-04-26)The amphipod crustacean Hyalella azteca was thought to be a single species, but recent molecular studies have indicated that it is a large cryptic species complex. Previous work has indicated that the H. azteca complex ... -
The Effects of Water Chemistry and Organism Source on Dysprosium Toxicity to Hyalella Azteca
(University of Waterloo, 2016-01-14)Rare earth elements (REEs) are a series of seventeen chemical elements, containing mostly lanthanides. Due to their multiple applications in industry and consumer electronics, global demand and production of REE has been ... -
Implications of copper and nickel exposure to different members of the Hyalella azteca species complex
(University of Waterloo, 2014-04-25)Hyalella azteca, an amphipod crustacean, is frequently used in freshwater toxicity tests. Since the mid-1980s, numerous organizations have collected and established cultures of H. azteca originating from localities across ... -
An integrative study on the controls of mercury (Hg) in the sediments and food webs of thermokarst lakes on the Arctic Coastal Plain of Alaska
(University of Waterloo, 2019-07-26)Arctic freshwater ecosystems are subject to profound climate-driven changes. Air temperatures are rising, leading to changes that include increased primary production and enhanced permafrost degradation. These and other ... -
Metal Mixture Toxicity to Hyalella azteca: Relationships to Body Concentrations
(University of Waterloo, 2008-01-25)A literature review of metal mixture interaction analyses identified that there was not a consistent method to determine the impact of metal mixtures on an aquatic organism. The review also revealed that a majority of the ... -
Toxicity and bioaccumulation kinetics of cadmium and potassium permanganate in two clades within the 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 species complex
(University of Waterloo, 2019-09-12)The freshwater amphipod 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 has been frequently used in toxicology since the 1980s due to its general sensitivity, ease of culture, and North America-wide geographic range. Over the past 20 years, ...
