The effects of herbivorous zooplankton on the sedimentation of particles out of the euphotic zone are examined with mathematical models, a large-scale field experiment, and descriptive data from a eutrophic lake. The theory is rooted in the population dynamics of phytoplankton and zooplankton and so explicitly accounts for the potential effect of zooplankton grazing on primary production and th...

Consisting of semi-circular body, coastal region in the Banten Bay holds a significant role for both marine ecosystem and human activities. The change its coastline due to erosion/sedimentation process may affect economic purposes. This study aims figure out evidence changes using remote sensing numerical model. recording satellite data from Landsat 5 TM, 7 ETM+ 8 OLI during 1990 - 2019, are em...

To date, life cycle assessment (LCA) does not include a methodology for assessing the impacts of plastic litter leaked to environment. This limits applicability LCA as tool compare potential single-use plastics and their alternatives on ecosystem quality human health. As contribution tackle this issue, work proposes simplified fate characterization factors (CFs) modeling two types microplastics...

Analytical ultracentrifugation (AUC) is a versatile and powerful method for the quantitative analysis of macromolecules in solution. AUC has broad applications for the study of biomacromolecules in a wide range of solvents and over a wide range of solute concentrations. Three optical systems are available for the analytical ultracentrifuge (absorbance, interference, and fluorescence) that permi...

BACKGROUND Taphonomic study of marine vertebrate remains has traditionally focused on single skeletons, lagerstätten, or bonebed genesis with few attempts to document environmental gradients in preservation. As such, establishment of a concrete taphonomic model for shallow marine vertebrate assemblages is lacking. The Neogene Purisima Formation of Northern California, a richly fossiliferous uni...

Sedimentation has been a standard methodology for particle size analysis since the early 1900s. In recent years laser diffraction is beginning to replace sedimentation as the prefered technique in some industries, such as marine sediment analysis. However, for the particle size analysis of soils, which have a diverse range of both particle size and shape, laser diffraction still requires evalua...

The trophic evolution of the Venice lagoon was analyzed by studying particulate collected monthly with sedimentation traps in many areas since 1989, and at Goro 2018–2019. Sedimentation rates were strongly related to presence macrophytes, which reduced sediment resuspension, anthropogenic pressures, such as clam harvesting naval-boat traffic, that triggered resuspension loss. highest mean annua...
