Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations. [PDF]
Biol Rev Camb Philos SocABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Adapting to an increasingly stressful environment: Experimental evidence for 'micro-evolutionary priming'. [PDF]
J Anim EcolOur study shows that exposure to low stress makes zooplankton populations more tolerant to extreme stress. This phenomenon, here called micro‐evolutionary priming, is rarely studied in animals. We provide strong evidence for its existence and explore its implications for the fate of populations in an increasingly stressful world.
