Chemical composition, sources and evolution of wintertime inorganic and organic aerosols in urban Shanghai, China

open access: yesFrontiers in Environmental Science, 2023
China experienced severe haze pollution in the past decades. However, systematic characterization of atmospheric fine particles with advanced measurement techniques has been very scarce in Shanghai, which is the largest megacity in China.

Polystyrene microplastic contamination versus microplankton abundances in two lagoons of the Florida Keys

open access: yesScientific Reports, 2021
A microscopic study of microplankton in two coastal lagoons in the Florida Keys coincidently, and unexpectedly, revealed the widespread presence of high concentrations of polystyrene microplastic particles.

Microbial and metabolic succession on common building materials under high humidity conditions. [PDF]

open access: yes, 2019
Despite considerable efforts to characterize the microbial ecology of the built environment, the metabolic mechanisms underpinning microbial colonization and successional dynamics remain unclear, particularly at high moisture conditions. Here, we applied

Study on Characteristic Spectrum and Multiple Classifier Fusion With Different Particle Size in Marine Sediments

open access: yesIEEE Access, 2020
Marine sediments record much information of the ecological process, which highly correlated with global and local environmental change. Particle size and its distributions of sediments indicate different ecological functions, thus are the key questions ...

On predicting particle capture rates in aquatic ecosystems.

open access: yesPLoS ONE, 2021
Recent advances in understanding the capture of moving suspended particles in aquatic ecosystems have opened up new possibilities for predicting rates of suspension feeding, larval settlement, seagrass pollination and sediment removal. Drawing on results

Marine Gel Interactions with Hydrophilic and Hydrophobic Pollutants

open access: yesGels, 2021
Microgels play critical roles in a variety of processes in the ocean, including element cycling, particle interactions, microbial ecology, food web dynamics, air–sea exchange, and pollutant distribution and transport.

Thermal decomposition of sulfur brown coal [PDF]

open access: yesE3S Web of Conferences
The influence of heating rate, temperature and particle size of sulfur brown coal from the Moscow region on the yield of coke residue and its elemental composition was studied.

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

open access: yesEnvironmental 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.

Bayesian deep learning for error estimation in the analysis of anomalous diffusion

open access: yesNature Communications, 2022
Modern single-particle-tracking techniques produce extensive time-series of diffusive motion in a wide variety of systems, from single-molecule motion in living-cells to movement ecology.

Density-and trait-mediated effects of a parasite and a predator in a tri-trophic food web [PDF]

open access: yes, 2014
1. Despite growing interest in ecological consequences of parasitism in food webs, relatively little is known about effects of parasites on long-term population dynamics of non-host species or about whether such effects are density- or trait- mediated ...
