Ben Parker, Demetra Andreou, Iain D. Green, J. Robert Britton

Fish and Fisheries > 22 > 3 > 467 - 488

Microplastics (MPs) are small, plastic particles of various shapes, sizes and polymers. Although well studied in marine systems, their roles and importance in freshwater environments remain uncertain. Nevertheless, the restricted ranges and variable traits of freshwater fishes result in their communities being important receptors and strong bioindicators of MP pollution. Here, the current knowledge...

Andrew L. Labaj, Adam Jeziorski, Joshua Kurek, Joseph R. Bennett, more

Freshwater Biology > 66 > 5 > 949 - 967

Cladocera serve as important bio‐ and paleo‐indicators of lake food webs and environmental conditions. The ecological optima of cladocerans are often established by regional‐scale calibration sets, with subsequent comparisons to limnological variables. However, due to logistical constraints when sampling large numbers of lakes, this approach often limits the length of the environmental gradients...
