Summary

ABSTRACT Excess fine sediment ( < 2 mm) is a pervasive stressor of aquatic systems at a global scale. To date, most research quantifying ecological response to deposited fine sediment has been conducted without distinguishing between the organic and inorganic components of fine sediment, leaving mechanistic understanding of how fine sediment affects macroinvertebrates lacking. To address this research gap, we examined the ecological responses of macroinvertebrates to various components of fine sediment stress (inorganic, organic and total mass). Using data collected from field surveys, first, we quantified invertebrate responses to fine sediment in two countries: New Zealand and the United Kingdom and second, we quantified whether ecological responses to the fine sediment components dif
