[THIS NONGEOGRAPHICDATASET HAS BEEN WITHDRAWN]. The resource includes data extracted from published laboratory studies investigating the impacts of microfibres (fibres < 5 mm in size) on various traits within aquatic organisms. Data were accessible on 19/06/2024 and represent studies from 2015 to 2024. The dataset includes measured responses in a range of aquatic organisms after microfibre exposure. Measures correspond to the following defined traits: 1. Development - healthy molting and growth of organs and structures. 2. Fecundity - number of offspring and quality of gametes. 3. Feeding - intake handling and egestion of resources. 4. Growth - change in organism weight, length or derived measures. 5. Hatching - number, emergence time and morphology of offspring. 6. Health - indices and measures of general organism wellbeing. 7. Survival - organisms alive at a particular time point. This dataset was created to collate microfibre study findings for meta-analyses and to identify gaps within the literature. This work was supported by NERC (NE/Y003985/1) as part of the Future Fibres Network project.
