Sinking Versus Suspended Particle Size Distributions in the North Pacific Subtropical Gyre

Geophysical Research Letters, 2020
The particle size distribution (PSD) is a fundamental property that influences all aspects of phytoplankton ecology. In particular, the size (e.g., diameter d [μm]) and sinking speed w (m/day) of individual particles are inextricable, but much remains ...

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.

Microscale ecology regulates particulate organic matter turnover in model marine microbial communities

Nature Communications, 2018
The degradation of particulate organic matter in the ocean is a central process in the global carbon cycle, the mode and tempo of which is determined by the bacterial communities that assemble on particle surfaces.

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 ...

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.

A Hybrid Particle Swarm Optimization-Genetic Algorithm for Multiobjective Reservoir Ecological Dispatching

Water resources management
Reservoir ecological dispatching is a complex system problem involving multiple objectives, multiple criteria and multiple phases. This study established a multiobjective ecological dispatching model of the Yinma River Basin in Changchun city based on ...

Biogeography of the free-living and particle-attached bacteria in Tibetan lakes.

FEMS Microbiology Ecology, 2019
The free-living (FL) and particle-attached (PA) bacteria have different dispersal potentials and ecological roles in aquatic ecosystems. However, our knowledge of their diversity and regional biogeographic patterns in high-altitude alpine lakes is ...

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

FEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.
