Effect of Mirex on Predator‐Prey Interaction in an Experimental Estuarine Ecosystem
TLDR
An alteration of predator-prey interaction due to mirex was manifested by a significant difference in survival of grass shrimp, Palaemonetes vulgaris, in control and treated tanks after one, two, or three days of predation by pinfish, Lagodon rhomboides.Abstract:
Tests of 14- to 16-days duration were conducted to determine the distribution and sublethal effects of mirex in an experimental estuarine ecosystem. The insecticide was translocated from water at concentrations of 0.011 to 0.13 μg/liter to sand, plant, and animal components. An alteration of predator-prey interaction due to mirex was manifested by a significant difference (X2 test, α = 0.05) in survival of grass shrimp, Palaemonetes vulgaris, in control and treated tanks after one, two, or three days of predation by pinfish, Lagodon rhomboides.read more

Indirect effects of contaminants in aquatic ecosystems.
TL;DR: Trophic cascades were found in 60% of the manipulative studies and, most commonly, primary producers increased in abundance when grazers were selectively eliminated by contaminants.

Indirect Effects in Aquatic Ecotoxicology: Implications for Ecological Risk Assessment
TL;DR: The current paper addresses the importance of indirect effects in an ecotoxicological context and concludes that failure to incorporate indirect effects into risk assessment paradigms may be a significant source of uncertainty in risk estimates.

New perspectives in ecotoxicology
TL;DR: A workshop on ecotoxicology was held by the Ecosystems Research Center at Cornell University as mentioned in this paper, with a focus on evaluating the effects of anthropogenic chemicals on ecosystems.

Margins of uncertainty in ecotoxicological hazard assessment
TL;DR: Data indicate that acute testing is not pointless; it offers a statistical base for the use of acute toxicity information in the hazard assessment of chemicals in the aquatic environment.

Use of biological indicator organisms to quantitate organochlorine pollutants in aquatic environments—A review
TL;DR: It is concluded that the use of any biological organism to elucidate the comparative pollution of different locations by organochlorines, or even to monitor changes in the availableOrganochlorine concentration at any one location with time, is open to criticism.
