Long-term change in benthopelagic fish abundance in the abyssal northeast Pacific Ocean [PDF]

, 2006
Food web structure, particularly the relative importance of bottom-up and top-down control of animal abundances, is poorly known for the Earth's largest habitats: the abyssal plains.

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

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.

Isotopic constraints on the atmospheric sources and formation of nitrogenous species in clouds influenced by biomass burning [PDF]

Atmospheric Chemistry and Physics, 2019
Predicting tropospheric cloud formation and subsequent nutrient deposition relies on understanding the sources and processes affecting aerosol constituents of the atmosphere that are preserved in cloud water.

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

Anthropic arguments outside of cosmology and string theory [PDF]

Belgrade Philosophical Annual, 2016
Anthropic reasoning has lately been strongly associated with the string theory landscape and some theories of particle cosmology, such as cosmological inflation. The association is not, contrary to multiple statements by physicists and philosophers alike,

Developing environmental flow targets for benthic macroinvertebrates in large rivers using hydraulic habitat associations and taxa thresholds

Ecological Indicators, 2023
Holistic environmental flows frameworks are built on our understanding of key flow-ecology relationships that support sensitive taxa and critical ecosystem functions under different flow and water level scenarios.

Truncated Levy Random Walks and Generalized Cauchy Processes

, 2011
A continuous Markovian model for truncated Levy random walks is proposed. It generalizes the approach developed previously by Lubashevsky et al. Phys. Rev. E 79, 011110 (2009); 80, 031148 (2009), Eur. Phys. J.

A cost-effective method to quantify biological surface sediment reworking [PDF]

, 2013
We propose a simple and inexpensive method to determine the rate and pattern of surface sediment reworking by benthic organisms. Unlike many existing methods commonly used in bioturbation studies, which usually require sediment sampling, our approach is ...
