Investigating shellfish deposition and landscape history at the Natia Beach site, Fiji [PDF]

, 2008
The relationship between environmental variation and subsistence practices is a central point of discussion in much Oceanic archaeology. While human predation can significantly reduce prey populations, environmental variation also contributes to ...

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

Bayesian deep learning for error estimation in the analysis of anomalous diffusion

Nature Communications, 2022
Modern single-particle-tracking techniques produce extensive time-series of diffusive motion in a wide variety of systems, from single-molecule motion in living-cells to movement ecology.

Differences in the trophic ecology of micronekton driven by diel vertical migration. [PDF]

, 2019
Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have different ...

Diverse diazotrophs are present on sinking particles in the North Pacific Subtropical Gyre. [PDF]

, 2019
Sinking particles transport carbon and nutrients from the surface ocean into the deep sea and are considered hot spots for bacterial diversity and activity.

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

Imaging Oxygen Distribution in Marine Sediments. The Importance of Bioturbation and Sediment Heterogeneity [PDF]

, 2008
The influence of sediment oxygen heterogeneity, due to bioturbation, on diffusive oxygen flux was investigated. Laboratory experiments were carried out with 3 macrobenthic species presenting different bioturbation behaviour patterns:the polychaetes ...

Assessing alkali activation of waste stone wool from greenhouses combined with direct foaming or granulation to obtain recycled plant substrate [version 1; peer review: 1 approved, 2 approved with reservations]

Open Research Europe
Background Stone wool is commonly used as a plant substrate in soilless cultivation and discarded after one growing season. Stone wool waste is difficult to recycle, and thus it is typically landfilled.

Interplay between particle size and microbial ecology in the gut microbiome

The ISME Journal
Abstract 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. Here, we analyzed FPS by
