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 ...

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 ...

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.

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.

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

Molecular 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]

, 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

A multi-scale distribution model for non-equilibrium populations suggests resource limitation in an endangered rodent. [PDF]

, 2014
Species distributions are known to be limited by biotic and abiotic factors at multiple temporal and spatial scales. Species distribution models, however, frequently assume a population at equilibrium in both time and space.

Towards an ecology of soil microplastics

, 2020
Microplastic pollution is a topic of increasing concern for the world's oceans, freshwaters and, most recently, soils. Microplastics have been found in soils across the globe.

Modeling of small sea floaters in the central Mediterranean Sea: seasonality of at-sea distributions [PDF]

, 2018
Floating marine debris represent a threat to marine and coastal ecology. Since the Mediterranean basin is one of the highly impacted regions, both by the coastal pollution as well as from sea traffic, the potential harm of a floating pollution on the ...
