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.

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,

Towards improved bioaerosol model validation and verification [PDF]

, 2018
Bioaerosols, comprised of bacteria, fungi and viruses are ubiquitous in ambient air. Known to adversely affect human health, the impact of bioaerosols on a population often manifests as outbreaks of illnesses such as Legionnaires Disease and Q fever ...

The vertical distribution and biological transport of marine microplastics across the epipelagic and mesopelagic water column. [PDF]

, 2019
Plastic waste has been documented in nearly all types of marine environments and has been found in species spanning all levels of marine food webs. Within these marine environments, deep pelagic waters encompass the largest ecosystems on Earth. We lack a

Viral ecology of organic and inorganic particles in aquatic systems: avenues for further research [PDF]

Aquatic Microbial Ecology, 2009
Viral abundance and processes in the water column and sediments are well studied for some systems; however, we know relatively little about virus-host interactions on particles and how particles influence these interactions. Here we review virus-prokaryote interactions on inorganic and organic particles in the water column.

Variation of grouped suspended sediment deposition and erosion in Shashi—Hankou reach after the construction of the Three Gorges Dam

Shui kexue jinzhan, 2022
The adjustment of scouring and silting downstream of reservoirs is a long-term complex process, which has a certain impact on flood protection, navigation and ecology.

Aquatic polymers can drive pathogen transmission in coastal ecosystems. [PDF]

, 2014
Gelatinous polymers including extracellular polymeric substances (EPSs) are fundamental to biophysical processes in aquatic habitats, including mediating aggregation processes and functioning as the matrix of biofilms.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

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.
