The effect of the sheep dip pesticide diazinon on behavioural and molecular markers in the freshwater shrimp Gammarus pulex [PDF]
, 2012 The purpose of this research was to determine the effects of the organophosphorothioate pesticide diazinon, its metabolite diazinon oxon and diazinon in a commercial formulation on the freshwater amphipod Gammarus pulex. It was found that diazinon in the

Predators vs. alien: differential biotic resistance to an invasive species by two resident predators [PDF]
, 2013 The success of invading species can be restricted by interspecific interactions such as competition and predation (i.e. biotic resistance) from resident species, which may be natives or previous invaders.

Invasive Ponto-Caspian amphipods and fish increase the distribution range of the acanthocephalan Pomphorhynchus tereticollis in the river Rhine [PDF]
, 2012 Non-indigenous species that become invasive are one of the main drivers of biodiversity loss worldwide. In various freshwater systems in Europe, populations of native amphipods and fish are progressively displaced by highly adaptive non-indigenous ...

Induction of Seaweed Chemical Defenses by Amphipod Grazing [PDF]
, 1996 Grazing by the generalist amphipod Ampithoe longimana induced increased concentrations of defensive secondary metabolites in the brown alga Dictyota menstrualis and made the seaweed less susceptible to further attack by the amphipod.

Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate
Environmental Toxicology, EarlyView.ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...
