Degradation and Preservation of Organic Matter in Marine Sediments
Organic matter that is deposited in aquatic sediments is subject to an intense diagenetic reactor that determines how much organic carbon is... -
Biological Markers for Anoxia in the Photic Zone of the Water Column
In this chapter we review the current state of knowledge on the occurrence of anoxic conditions in the water column of past depositional systems... -
Controls on the Carbon Isotopic Compositions of Lipids in Marine Environments
Organic carbon isotopes have long been used to study modern and ancient biogeochemical processes. Controls on the isotopic composition of organic... -
Sources and Cycling of Organic Matter in the Marine Water Column
The organic carbon cycle operates on multiple time scales with a only small fraction of the global reservoir actively exchanged. For the marine... -
Molecular Tools for the Analysis of DNA in Marine Environments
In the last decade, microbial ecologists have increasingly applied molecular techniques to investigate microorganisms in natural environments. The... -
Atmospheric Transport of Terrestrial Organic Matter to the Sea
The transport of atmospheric particles with associated terrestrial organic matter to the oceans is an important process affecting various global... -
Sources and Fate of Organic Contaminants in the Marine Environment
The sources, levels, and fate of organic contaminants of major concern in the marine environment are reviewed. Spatial distributions among the... -
Lipid Markers for Marine Organic Matter
An astonishing variety of different lipids have been found in marine sediments and the water column attesting to the diversity of biosynthetic... -
Pigment Markers for Phytoplankton Production
Chlorophylls and carotenoids are commonly used as quantitative biomarkers for the composition and biomass of marine phytoplankton. This chapter... -
Isotopic Tracers of the Marine Nitrogen Cycle: Present and Past
The oceanic nitrogen cycle consists of a web of microbially mediated transformations driven in part by the large range in possible nitrogen... -
Early oxidative stress and DNA damage in Aβ-burdened hippocampal neurons in an Alzheimer’s-like transgenic rat model
Oxidative stress is a key contributor to AD pathology. However, the earliest role of pre-plaque neuronal oxidative stress, remains elusive. Using...

A versatile functional interaction between electrically silent KV subunits and KV7 potassium channels
Voltage-gated K + (K V ) channels govern K + ion flux across cell membranes in response to changes in membrane potential. They are formed by the assembly...

Long sediment-laden algal turf likely impairs coral recovery on Florida’s coral reefs
Coral reefs in the Florida Reef Tract have seen protracted loss of coral over the past several decades due to a variety of disturbances from marine...

Identification of volatile metabolites produced from levodopa metabolism by different bacteria strains of the gut microbiome
Interspecies pathways in the gut microbiome have been shown to metabolize levodopa, the primary treatment for Parkinson’s disease, and reduce its...

C4-like Sesuvium sesuvioides (Aizoaceae) exhibits CAM in cotyledons and putative C4-like + CAM metabolism in adult leaves as revealed by transcriptome analysis
BackgroundThe co-occurrence of C 4 and CAM photosynthesis in a single species seems to be unusual and rare. This is likely due to the difficulty in...
