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 ...

Spatiotemporal Dynamics of Free-Living and Particle-Associated Vibrio Communities in the Northern Chinese Marginal Seas

Applied and Environmental Microbiology, 2019
The dynamics of Vibrio communities have been shown in many marine habitats that are close to land, including estuary or harbor areas. Here, we investigated the spatiotemporal dynamics of Vibrio populations in the northern Chinese marginal seas, spanning ...

Transition probabilities for general birth-death processes with applications in ecology, genetics, and evolution

, 2011
A birth-death process is a continuous-time Markov chain that counts the number of particles in a system over time. In the general process with $n$ current particles, a new particle is born with instantaneous rate $\lambda_n$ and a particle dies with ...

Behavior and Bio-Interactions of Anthropogenic Particles in Marine Environment for a More Realistic Ecological Risk Assessment [PDF]

Frontiers in Environmental Science, 2020
Owing to production, usage, and disposal of nano-enabled products as well as fragmentation of bulk materials, anthropogenic nanoscale particles (NPs) can enter the natural environment and through different compartments (air, soil, and water) end up into the sea.

Diversity of filter feeding and variations in cross-flow filtration of five ram-feeding fish species

Frontiers in Marine Science, 2023
IntroductionFilter-feeding fish separate food particles from the surrounding water by cross-flow filtration in which a suspension flows parallel to a porous filter medium, thereby transporting particles along the surface.MethodsHere, we investigate cross-
