Interplay between particle size and microbial ecology in the gut microbiome [PDF]
The ISME JournalAbstract Physical particles can serve as critical abiotic factors that structure the ecology of microbial communities. For non-human vertebrate gut microbiomes, fecal particle size (FPS) has been known to be shaped by chewing efficiency and diet. However, little is known about what drives FPS in the human gut.

Particle motion: the missing link in underwater acoustic ecology [PDF]
Methods in Ecology and Evolution, 2016 Summary Sound waves in water have both a pressure and a particle‐motion component, yet few studies of underwater acoustic ecology have measured the particle‐motion component of sound. While mammal hearing is based on detection of sound pressure, fish and invertebrates (i.e. most aquatic animals) primarily sense sound using particle motion.

Particles, environments, and possible ecologies in the Jovian atmosphere [PDF]
The Astrophysical Journal Supplement Series, 1976 The eddy diffusion coefficient is estimated as a function of altitude, separately for the Jovian troposphere and mesosphere. Complex organic molecules produced by the Ly alpha photolysis of methane may possibly be the absorbers in the lower mesosphere which account for the low reflectivity of Jupiter in the near ultraviolet.

Viral ecology of organic and inorganic particles in aquatic systems: avenues for further research [PDF]
Aquatic Microbial Ecology, 2009 Viral abundance and processes in the water column and sediments are well studied for some systems; however, we know relatively little about virus-host interactions on particles and how particles influence these interactions. Here we review virus-prokaryote interactions on inorganic and organic particles in the water column.

Theoretical Mechanics of Particle Capture: Predictions for Hydropsychid Caddisfly Distributional Ecology [PDF]
The American Naturalist, 1990 Computer simulations based on equations developed earlier were used to analyze theoretically the effects of six parameters on particle capture by hydropsychid caddisfly nets. If assumptions that form the basis of these simulations are valid, the following statements can be made. (1) Nets with fine meshes capture suspended particles at a higher rate per

Tracer-based investigation of organic aerosols in marine atmospheres from marginal seas of China to the northwest Pacific Ocean [PDF]
Atmospheric Chemistry and Physics, 2020 We investigated the geographic distributions of organic tracers in total suspended particles over the marginal seas of China, including the Yellow and Bohai seas (YBS) and the South China Sea (SCS), and the northwest Pacific Ocean (NWPO) in spring, when ...

Application of microbial analyses to feeds and potential implications for poultry nutrition
Poultry Science, 2022 : Poultry nutrition and feed manufacturing are interrelated for a variety of reasons. Diet formulation is essential for optimizing bird growth and feed conversion, but compositional differences and the presence of certain feed additives can alter the ...

Organosolv lignin particles as an ecological reagents in the Kupfershiefer copper ore flotation
Physicochemical Problems of Mineral Processing, 2023 Mineral separation relies heavily on the process of flotation. This study explored the feasibility of using organosolv lignin nanoparticles and microparticles (OLP) as a greener alternative to xanthates in the flotation process for mineral separation. Xanthates are widely used but pose environmental and health risks. The efficiency of OLP as collectors
