Chemical Mixtures and Multiple Stressors: Same but Different? [PDF]

Environmental Toxicology and Chemistry, 2023
Abstract Ecosystems are strongly influenced by multiple anthropogenic stressors, including a wide range of chemicals and their mixtures. Studies on the effects of multiple stressors have largely focussed on nonchemical stressors, whereas studies on chemical mixtures have largely ignored other stressors.

Stressor fluctuations alter mechanisms underpinning seagrass responses to multiple stressors

Marine Pollution Bulletin
Multiple anthropogenic stressors degrade ecosystems globally. A key knowledge gap in multiple stressor research is how variability in stressor intensity (i.e., fluctuations) and synchronicity (i.e., timing of fluctuations) affect biological responses, and the mechanisms underpinning responses.

Interaction of multiple stressors

, 2009
In natural waters, organisms are exposed to a mixture of chemicals and are also affected by other stressors such as temperature, ultraviolet radiation, parasites and pathogens. At Eawag, the risks associated with multiple stressors are being assessed using various methods, including analysis of altered protein expression patterns.

Multiple Stressors Simplify Freshwater Food Webs

Global Change Biology
ABSTRACTGlobally, freshwater ecosystems are threatened by multiple stressors, yet our knowledge of how they interact to affect food web structure remains scant. To address this knowledge gap, we conducted a large‐scale mesocosm experiment to quantify the single and combined effects of three common anthropogenic stressors: warming, increased nutrient ...

A meta-analysis of work demand stressors and job performance: examining main and moderating effects [PDF]

, 2008
We quantitatively integrated 169 samples (N= 35,265 employees) that have been used to investigate the relationships of the following 7 work-related stressors with job performance: role ambiguity, role conflict, role overload, job insecurity, work–family ...

Hypothesis-Driven Research on Multiple Stressors: An Analytical Framework for Stressor Interactions. [PDF]

Ecol Evol
ABSTRACT Identifying and characterizing stressor interactions is central to multiple stressor research. Such interactions refer to stronger (synergism) or weaker (antagonism) joint effects of co‐occurring stressors on biological entities, when compared to the predictions of a theoretical null model.

Multiple Stressors

, 2023
AbstractThis book has mostly considered marine contamination and the biological effects of contaminants acting as single stressors. However, marine environments are rarely exposed to a single stressor, but rather experience a complex mix of many stressors.

Urban Environments Promote Adaptation to Multiple Stressors. [PDF]

Ecol Lett
ABSTRACT Anthropogenic activities have drastically changed environmental conditions worldwide, negatively impacting biodiversity and ecosystem services. At the same time, the majority of the human population lives in urban areas that are greatly altered from natural habitats.

Multiple stressors affect function rather than taxonomic structure of freshwater microbial communities. [PDF]

NPJ Biofilms Microbiomes
Microbial community responses to environmental stressors are often characterised by assessing changes in taxonomic structure, but such changes, or lack thereof, may not reflect functional changes that are critical to ecosystem processes.
