Atmo-ecometabolomics: a novel atmospheric particle chemical characterization methodology for ecological research [PDF]

Environmental Monitoring and Assessment, 2019
Aerosol particles play important roles in processes controlling the composition of the atmosphere and function of ecosystems. A better understanding of the composition of aerosol particles is beginning to be recognized as critical for ecological research to further comprehend the link between aerosols and ecosystems.

Microplastic burden in marine benthic invertebrates depends on species traits and feeding ecology within biogeographical provinces

Nature Communications, 2023
The microplastic body burden of marine animals is often assumed to reflect levels of environmental contamination, yet variations in feeding ecology and regional trait expression could also affect a species’ risk of contaminant uptake.
