Bioavailability and toxicity of nickel to freshwater organisms : a modeling approach
… the acute and chronic toxicity of nickel to freshwater organisms. For each testing organism (a unicellular green alga, an aquatic invertebrate and a fish) a bioavailability model was developed capable of accurately predicting nickel toxicity in both artificial and natural waters. An important …

Bioavailability models for predicting copper toxicity to freshwater organisms - Biobeschikbaarheidsmodellen voor het voorspellen van de toxiciteit van koper voor zoetwaterorganismen
Aquatische ecotoxicologie heeft als uiteindelijk doel het evalueren van risico’s van natuurlijke en antropogene stoffen voor aquatische ecosystemen. Dit proefschrift is specifiek gericht op het gebruik van toxiciteitsgegevens voor koper in zoetwater ecosystemen voor risico-evaluatie procedures en …

The Influence of Water Quality Characteristics on Vanadium Toxicity to Model Aquatic Organisms
… region that could present a risk for aquatic organisms. Petroleum coke (PC) has been experimentally used to treat oil sands process-affected water (OSPW) to reduce organic toxicants. However, PC contains up to 1,000 mg of V per kg of PC, and during OSPW treatment V leaches from coke reaching …

Artificial Light at Night Alters Physiology, Behavior, and Reproduction in the Western Mosquitofish (Gambusia affinis)
… of multiple other taxa. The effects of ALAN on freshwater organisms, however, are largely understudied as compared to terrestrial taxa. I investigated how ALAN affects the physiology, behavior, and reproduction of a widespread freshwater fish. Gambusia affinis are small livebearing fish often …

Acute Toxicity of Ammonia and Copper to Mussel (Bivalvia: Unionidae) Glochidia Inside and Outside of Conglutinates
… pollutants that are toxic to the most sensitive freshwater organisms. Freshwater mussels (Unionoida) are unusually sensitive to certain pollutants and therefore have potential to drive water quality standards. However, data must be based on the normal routes and duration of exposure of each life …

Scale dependent genetic structure of Idaho Giant salamanders (Dicamptodon aterrimus) in stream networks
… structure constrains population processes of freshwater organisms, with individual, population and community level consequences. This consistent structure provides a framework in which examination of life-history influences on population genetic structure may provide general insight. I …

Evaluating the emerging environmental risks of mycotoxins in freshwater ecosystems.
… interest into the potential transference into freshwaters. Multiple reports of mycotoxin occurrence in freshwater samples have led to their consideration as natural chemicals of emerging concern, particularly with ZON seen to act in an oestrogenic nature, yet the ecotoxicological data to …

The Toxicity of Ammonia to the Summer Flounder (Paralychtus Dentatus), Atlantic Silverside (Menidia Menidia), and Quahog Clam (Mercenaria Mercenaria)
… exists on the toxicity of ammonia to saltwater organisms. Prior to this research, the chronic criterion was based on two saltwater and four freshwater organisms. This research was conducted to add additional data so more appropriate criteria may be set. Two saltwater fish, the Summer Flounder …

Bivalve molluscs as environmental monitors and tools for sustainable water management
Freshwater environments are capable of providing a wide range of vital ecosystem services, from basic provision of drinking water to energy production, waste removal to recreation. Well-managed water resources allow such precious services to be preserved. However, anthropogenic influences have led …

River temperature behaviour in changing environments: trends, patterns at different spatial and temporal scales and role as a stressor
… is crucial to better understand the responses of freshwater biota to simultaneously acting stressors such as changing river temperatures, hydrology and river quality aspects (e.g. dissolved oxygen levels). So far, only a handful of studies have explored the impacts of multiple stressors, including …
