Soil Viruses Are Underexplored Players in Ecosystem Carbon Processing

open access: yesmSystems, 2018
Rapidly thawing permafrost harbors ∼30 to 50% of global soil carbon, and the fate of this carbon remains unknown. Microorganisms will play a central role in its fate, and their viruses could modulate that impact via induced mortality and metabolic ...

Growing aridity poses threats to global land surface

open access: yesCommunications Earth & Environment
Global warming has impacted water cycle, but not exist a global study of the changes at global scale of the impacts on water available for plants. Here, cloud-optimized monthly aggregated climate reanalysis from the European Centre for Medium-Range ...

Microbiology and Ecology of Methylated Amine Metabolism in Marine Ecosystems.

open access: yesCurrent Issues in Molecular Biology, 2019
Methylated amines (MAs) are ubiquitous in marine ecosystems, found from surface seawaters to sediment pore waters. These volatile ammonium analogs play important roles in biogeochemical cycles of carbon and nitrogen in the marine water column.

Coarse particles and hospital admissions due to respiratory diseases in children. An ecological time series study [PDF]

open access: yesSao Paulo Medical Journal, 2018
Exposure to particulate matter (PM) is associated with hospitalizations due to respiratory diseases among children.An ecological time series study was carried out to identify the role of coarse fractions of particulate matter (PM10-2.5) in hospitalizations among children up to 10 years of age, in Piracicaba (SP) in the year 2015.A generalized additive ...

Ecological non-linear state space model selection via adaptive particle Markov chain Monte Carlo (AdPMCMC) [PDF]

open access: yes, 2010
We develop a novel advanced Particle Markov chain Monte Carlo algorithm that is capable of sampling from the posterior distribution of non-linear state space models for both the unobserved latent states and the unknown model parameters.

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

open access: yes, 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 ...

Bioinspired Materials, Designs, and Manufacturing Strategies for Advanced Impact‐Resistant Helmets

open access: yesAdvanced Engineering Materials, EarlyView.
This review explores how bioinspired materials, structures, and manufacturing strategies transform helmet design to achieve enhanced impact resistance. Drawing inspiration from nacre, porcupine quills, beetle exoskeletons, and skull architectures, it highlights advances in auxetic lattices, nanocomposites, and functionally graded foams.

Polytraits : a database on biological traits of marine polychaetes [PDF]

open access: yes, 2014
The study of ecosystem functioning – the role which organisms play in an ecosystem – is becoming increasingly important in marine ecological research. The functional structure of a community can be represented by a set of functional traits assigned to ...

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

open access: yesAdvanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Comparing the Fate of eDNA by Particle Sizes and Molecule Lengths in Recirculating Streams

open access: yesEnvironmental DNA
The detection of environmental DNA (eDNA) has revolutionized aquatic species monitoring, yet interpreting eDNA data remains challenging due to gaps in our understanding of eDNA ecology (i.e., origin, state, transport, and fate) and variability in how ...
