Do Antarctic benthic invertebrates show an extended level of eurybathy?

Overview of the chemical ecology of benthic marine invertebrates along the western Antarctic peninsula.

Thirteen years ago in a review that appeared in the American Zoologist, we presented the first survey of the chemical and ecological bioactivity of Antarctic shallow-water marine invertebrates. In essence, we reported that despite theoretical predictions to the contrary the incidence of chemical defenses among sessile and sluggish Antarctic marine invertebrates was widespread. Since that time w...

Benthic Invertebrates of the Lower West River

The purpose of this study was to document existing benthic organisms of the lower West River in New Haven and West Haven, Connecticut, in order to enable monitoring of salt marsh restoration. Seventeen sites were sampled between the Chapel Street Bridge and the mouth of the West River during the month of July 1995. All sites contained polychaete worms and other organisms typical of estuarine sy...

The effect of Rainbow trout farms effluents on benthic macro-invertebrates of Marber River in Semirom

The effect of Rainbow trout farms effluents on benthic macro-invertebrates of Marber River in Semirom city was investigated in spring and summer of 2013. Sampling from benthic macro-invertebrates was done monthly using Surber sampler (mouth area of 30.5 * 30.5 cm with a 500 mesh net) at entrance, discharge and far from three fish farms. In addition to measuring physical and chemical parameters ...

The Distribution of Antarctic Marine Benthic Communities

The Polar Frontal Zone, although predominantly a surface feature, forms a natural northernmost boundary for defining the Southern Ocean, and relatively few benthic organisms have distributions which cross this boundary. Many Antarctic benthic plants and animals have circumpolar distributions but some broad geographical subdivisions may be made. Detailed studies of community distribution are few...
