Interactions between effects of environmental chemicals and natural stressors: a review.
Ecotoxicological effect studies often expose test organisms under optimal environmental conditions. However, organisms in their natural settings rarely experience optimal conditions. On the contrary,Expand

Although the concept of biomagnification, that is, an increase in the concentration of anthropogenic pollutants along trophic chains, has been applied to many chemicals (e.g., Gilles et al., 1973;Expand

Time to death response in carabid beetles exposed to multiple stressors along a gradient of heavy metal pollution.
We investigated the responses of invertebrates inhabiting polluted environments to multiple stressors. Carabid beetles (Pterostichus oblongopunctatus F.) were subjected to food deprivation andExpand

Heat shock proteins (HSP70) as biomarkers in ecotoxicological studies.
Hsp70, so-called stress proteins, were studied in the centipede Lithobius mutabilis when exposed in laboratory tests to different concentrations of the insecticide dimethoate (DMT; 0, 0.012, 0.111 mgExpand

Exposure and effects assessments of Bt-maize on non-target organisms (gastropods, microarthropods, mycorrhizal fungi) in microcosms
Summary Potential differences between Bt-maize (MEB307 expressing the insecticidal Cry1Ab protein) and a near-isogenic non-Bt variety (Monumental) in their influence on the garden snail (HelixExpand

Metals, being non-degradable, tend to accumulate in animals and hence long-term exposure even to low concentrations of metals may lead to harmful effects. From the physiological point of view,Expand

Metal Kinetics and Respiration Rates in F1 Generation of Carabid Beetles (Pterostichus oblongopunctatus F.) Originating From Metal-Contaminated and Reference Areas
We investigated resistance to metals in carabid beetles inhabiting metal-polluted and reference areas. Chronic multigeneration exposure to toxic metal concentrations may potentially result inExpand

Interactions between toxic chemicals and natural environmental factors--a meta-analysis and case studies.
The paper addresses problems arising from effects of natural environmental factors on toxicity of pollutants to organisms. Most studies on interactions between toxicants and natural factors,Expand

Decreased Energetic Reserves, Morphological Changes and Accumulation of Metals in Carabid Beetles (Poecilus cupreus L.) Exposed to Zinc- or Cadmium-contaminated Food
The prime objective of the study was to find out whether contamination of food with metals affects body size, energetic reserves and developmental instability in ground beetles (Poecilus cupreus L.:Expand

Activity of carboxylesterase and glutathione S-transferase in different life-stages of carabid beetle (Poecilus cupreus) exposed to toxic metal concentrations.
Among the cytoplasmatic enzymes responsible for neutralization of organic xenobiotics, carboxylesterases (CarE) and glutathione S-transferases (GST) play important roles. Our study tested to whatExpand
