The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Bacteriophage Distributions and Temporal Variability in the Ocean’s Interior

open access: yesmBio, 2017
Bacteriophages are numerically the most abundant DNA-containing entities in the oligotrophic ocean, yet how specific phage populations vary over time and space remains to be fully explored.

A Taxonomy of Predictive Maintenance as a Basis for Supra‐Regional Sustainability Monitoring—Literature Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The concept of predictive maintenance in advanced manufacturing systems is crucial from the point of view of resource efficiency in the era of high competitiveness forced by energy transformation in the digital economy. Against the backdrop of sustainability and the opportunities a data cooperative offers, the combination of predictive ...

Resolving environmental drivers of microbial community structure in Antarctic soils [PDF]

open access: yes, 2009
Antarctic soils are extremely cold, dry, and oligotrophic, yet harbour surprisingly high bacterial diversity. The severity of environmental conditions has constrained the development of multi-trophic communities, and species richness and distribution is ...

Rubrolides A, D, P, T, U: Total Syntheses and Antibacterial Evaluation of Highly Brominated Marine Natural Products

open access: yesChemistryEurope, EarlyView.
Following the Danube Flow. The first total syntheses of highly brominated rubrolides T, U, and U‐analog, together with the efficient and divergent syntheses of rubrolides A, D, and P. The dibrominated key intermediate, obtained via a Suzuki‐Miyaura cross‐coupling reaction, is the centerpiece of the synthesis.

Microbiome depletion and recovery in the sea anemone, Exaiptasia diaphana, following antibiotic exposure

open access: yesmSystems
Microbial species that comprise host-associated microbiomes play an essential role in maintaining and mediating the health of plants and animals. While defining the role of individual or even complex communities is important toward quantifying the effect

Assessment of the microbial communities associated with white syndrome and brown jelly syndrome in aquarium corals [PDF]

open access: yes, 2013
Bacterial and ciliate assemblages associated with aquarium corals displaying white syndrome (WS) and brown jelly syndrome (BJS) were investigated. Healthy (n = 10) and diseased corals (WS n = 18; BJS n = 3) were analysed for 16S rRNA gene bacterial ...

Identification of Natural Isonitriles Through Ligation to an Azomethine Imine Probe

open access: yesChemistry – A European Journal, EarlyView.
The azomethine imine (AMI)–isonitrile (NC) ligation allowed for the chemoselective detection of natural isonitriles in bacteria and fungi. The reactivity‐based screening establishes a new stereogenic center, thereby allowing for facile distinction between chiral and achiral isonitriles. The work also unraveled a unique reactivity of isonitriles bearing

Testing the priming effect in the deep ocean: are microorganisms too starved to consume recalcitrant organic carbon?

open access: yesApplied and Environmental Microbiology
Deep ocean dissolved organic carbon (DOC) is one of the largest pools of reduced carbon on Earth. Many DOC compounds escape microbial degradation and persist for thousands of years in the ocean. Although many hypotheses have been proposed, the mechanisms

An Investigation into the Suitability of Sulfate-Reducing Bacteria as Models for Martian Forward Contamination [PDF]

open access: yes, 2018
The NASA Planetary Protection policy requires interplanetary space missions do not compromise the target body for a current or future scientific investigation and do not pose an unacceptable risk to Earth, including biologic materials.
