China’s regulatory respond to plastic pollution: Trends and trajectories
(Peer reviewed; Journal article, 2022)Despite China having an international reputation as one of the largest contributors to plastic pollution in the world’s oceans, research analyzing China’s regulatory approach to governing plastic has been limited and ... -
Chitinase digestion for the analysis of microplastics in chitinaceous organisms using the terrestrial isopod Oniscus asellus L. as a model organism
(Peer reviewed; Journal article, 2021)Chitinaceous organisms have been found to ingest microplastic; however, a standardised, validated, and time- and cost-efficient method for dissolving these organisms without affecting microplastic particles is still required. ... -
Chloropicophyceae, a new class of picophytoplanktonic prasinophytes
(Journal article; Peer reviewed, 2017)Prasinophytes are a paraphyletic group of nine lineages of green microalgae that are currently classified either at the class or order level or as clades without formal taxonomic description. Prasinophyte clade VII comprises ... -
