Defective subviral particles modify ecological equilibria and enhance viral coexistence

Frontiers in Virology, 2022
ABSTRACTCooperation is a main driver of biological complexity at all levels. In the viral world, gene sharing among viral genomes, complementation between genomes or interactions within quasispecies are frequently observed. In this contribution, we explore the advantages that flexible associations between fully fledged viruses and subviral entities ...

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.

Particulate and Dissolved Black Carbon in Bohai and Laizhou Bays, China: Distributions, Sources, and Contrasts Under Two Distinct Fluvial Hydrological Regimes

Frontiers in Earth Science, 2021
Coastal seas, including coastal bays, are the geographically critical transitional zone that links terrestrial and open oceanic ecosystems. Organic carbon cycling in this area is a dynamic and disproportionally key component in the global carbon cycle ...

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

Scientific 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.

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

Frontiers 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.

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

IEEE 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 ...

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.
