Global data on earthworm abundance, biomass, diversity and corresponding enviro...
Phillips, Helen R. P.; Bach, Elizabeth M; Bartz, M. L. C.; Bennett, Joanne M.; Beugnon, Rémy; Briones, Maria J. I.; Brown, George G.; Ferlian, OlgaEarthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site l...
Salinity changes impact of hazardous chemicals in Enchytraeus albidus
Patrício Silva, Ana L.; Amorim, Mónica J. B.; Holmstrup, MartinSupralittoral ecosystems are among the most challenging environments for soil organisms, particularly when salinity fluctuations are involved, frequently combined with the presence of contaminants as a result of intense anthropogenic activities. Knowledge of how salinity influences the effect of contaminants in supralittoral species is crucial for determining the safety factors required when extrapolating resul...
Importance of freeze-thaw events in low temperature ecotoxicology of cold toler...
Patrício Silva, Ana L.; Enggrob, Kirsten; Slotsbo, Stine; Amorim, Mónica J. B.; Holmstrup, MartinDue to global warming it is predicted that freeze-thaw cycles will increase in Arctic and cold temperate regions. The effects of this variation becomes of particular ecological importance to freeze-tolerant species when it is combined with chemical pollutants. We compared the effect of control temperature (2 °C), daily freeze-thaw cycles (2 to -4 °C) and constant freezing (-2 °C) temperatures on the cold-tolera...
Interactions between effects of environmental chemicals and natural stressors: ...
Holmstrup, Martin; Bindesbol, Anne-Mette; Oostingh, Gertie Janneke; Duschl, Albert; Scheil, Volker; Köhler, Heinz-R.; Loureiro, SusanaEcotoxicological effect studies often expose test organisms under optimal environmental conditions. However, organisms in their natural settings rarely experience optimal conditions. On the contrary, during most of their lifetime they are forced to cope with sub-optimal conditions and occasionally with severe environmental stress. Interactions between the effects of a natural stressor and a toxicant can sometim...
Interactions between toxic chemicals and natural environmental factors - a meta...
Laskowski, Ryszard; Bednarska, Agnieszka J.; Kramarz, Paulina E.; Loureiro, Susana; Scheil, Volker; Kudłek, Joanna; Holmstrup, MartinThe 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, including those completed in the EU project NoMiracle (Novel Methods for Integrated Risk Assessment of Cumulative Stressors in Europe) described herein, showed that effects of toxic chemicals on organisms can differ vastly ...
