Defective subviral particles modify ecological equilibria and enhance viral coexistence

open access: yesFrontiers 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 ...

Copepods encounter rates from a model of escape jump behaviour in turbulence [PDF]

open access: yes, 2017
A key ecological parameter for planktonic copepods studies is their interspecies encounter rate which is driven by their behaviour and is strongly influenced by turbulence of the surrounding environment.

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

open access: yesFrontiers 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

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.

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.

Physical Connectivity Between the NE Atlantic Seamounts [PDF]

open access: yes, 2020
Within the Portuguese Exclusive Economic Zone, the Great Meteor and Madeira-Tore complexes are highly productive areas, which are likely to be classified as marine protected areas (MPAs) due to their ecological vulnerability.

The relationship between eDNA particle concentration and organism abundance in nature is strengthened by allometric scaling

open access: yesMolecular Ecology, 2020
Organism abundance is a critical parameter in ecology, but its estimation is often challenging. Approaches utilizing eDNA to indirectly estimate abundance have recently generated substantial interest.

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
