Raw data and R code for plots

What is this page?

This page shows the raw data and R code to reproduce the figures in Hiki & Nakajima (2022, JWET).

Objective

Microplastics adversely affect organisms through physical damage, inhibition of food assimilation, and/or toxicity of chemical leachates. To investigate the influence of feeding mode on microplastic ingestion by benthic organisms, we performed microplastic ingestion experiments using polystyrene microbeads (diameter: 4.1 and 20.6 μm) and the estuarine benthic amphipod Grandidierella japonica, which can switch between filter-feeding and deposit-feeding modes.
