The impact of fine sediment on macro-invertebrates
J. I. Jones,John F. Murphy,Adrian L. Collins,Adrian L. Collins,David Sear,Pamela S. Naden,Patrick D. Armitage +6 more
TL;DR: In this article, the authors review the evidence available for deriving improved guidelines on the loading of fine sediment to rivers based on the impact on macro-invertebrates and conclude that existing water quality guidelines for sediment management are unlikely to be appropriate.
Journal ArticleDOI
Effects of diet, body size, age and temperature on growth rates in the amphipod Gammarus pulex
TL;DR: Increase in body wet weight of Gammarus pulex fed on decaying elm leaves was followed to senescence and death and weight-specific absorption in the gut was highest in juveniles and decreased with increasing body weight; relative efficiency of absorption was generally lower in the larger individuals.
Journal ArticleDOI
Sexual size dimorphism in species with asymptotic growth after maturity
TL;DR: This study supports earlier suggestions that information on growth and maturation patterns may be useful, if not essential, for comparative studies of sexual size dimorphism in taxa with asymptotic growth after maturity.

Freshwater Sediment Toxicity Bioassessment: Rationale for Species Selection and Test Design
John P. Giesy,Robert A. Hoke +1 more
TL;DR: The usefulness of a battery of assays for the screening evaluation of sediment toxicity and statistical considerations which are important in the development of study designs and the analysis of results from the battery of proposed assays are discussed.
Journal ArticleDOI
PET microplastics do not negatively affect the survival, development, metabolism and feeding activity of the freshwater invertebrate Gammarus pulex.
TL;DR: It is argued that the autecology needs to be taken into account and that research should focus on identifying traits that render species susceptible to microplastic exposure, as well as the species-specific morphological, physiological and behavioral traits.

Effects of Temperature on Growth of Zooplankton, and the Adaptive Value of Vertical Migration
TL;DR: It is shown that Bělehradek's temperature function gives a close fit to size and development rate of several species of zooplankters growing in adequate food supply, although conclusions do not depend on the theoretical content of this equation.
