Negative effects of increased ozone concentrations and heat stress on bumblebees are exacerbated by microplastics

Abstract The intensity of environmental stressors increases due to global change. Under natural conditions, insect pollinators are experiencing multiple stressors simultaneously which may exacerbate the negative effects of individual stressors. Using a fully crossed factorial des...

Oxidative Stressafter Pollutant Exposure DependsStrongly on Experimental Design and Pollutant Properties in Annelids:A Meta-Analysis

Abstract Measurements of oxidative stress are often performed to assess a species’ general sublethal stress response to a pollutant. However, oxidative stress bioassays often produce seemingly ambiguous results, and the drivers that lead to these differences are largely unknown....
