The burial of organic matter (OM) in marine sediments represents the major link between
“active” surface pools of carbon in the oceans, atmosphere, on land, and in marine …

Many strategies have been used to increase the number of bacterial cells that can be grown
from environmental samples but cultivation efficiency remains a challenge for microbial …

Half of the microbial cells in the Earth's oceans are found in sediments. Many of these cells
are members of the Archaea, single-celled prokaryotes in a domain of life separate from …

In both marine and freshwaters, the concentration of dissolved organic nitrogen (DON)
frequently exceeds that of dissolved inorganic nitrogen (DIN), including ammonium, nitrate …

The processes occurring in surface marine sediments have a profound effect on the local
and global cycling of many elements. This graduate text presents the fundamentals of …

Viruses contribute to the mortality of marine microbes, consequentially altering biological
species composition and system biogeochemistry. Although it is well established that host …

The stable isotopes of nitrogen offer a unique perspective on changes in the nitrogen cycle,
past and present. However, the presence of multiple forms of nitrogen in marine sediments …

Organic matter in seawater is a complex mixture of organic compounds with diverse
chemical compositions, physical structures, and reactivity. For heterotrophic bacteria in the …

Microbial contributions to the detritus of two vascular plant tissues, smooth cordgrass
(Spartina alterniflora) and black mangrove leaves (Avicennia germinans), were estimated …

The majority of ancient DNA studies on human specimens have utilised teeth and bone as a
source of genetic material. In this study the levels of endogenous contamination (ie present …
