Microbial activities drive the global nitrogen cycle, and in the past few years, our understanding
of nitrogen cycling processes and the micro-organisms that mediate them has changed …

Publisher Summary This chapter describes the biological efficiencies in multiple-cropping
systems. Many multiple-cropping systems persist on farms on which resources are limited and …

… Surface sediments were collected from San Francisco Bay and Bahiáa del Tóbari, Mexico
(Gulf of California), using box cores deployed off small vessels in July 2004 and October 2004, …

Cover crops (CCs) can provide multiple soil, agricultural production, and environmental
benefits. However, a better understanding of such potential ecosystem services is needed. We …

Nitrification plays an important role in marine biogeochemistry, yet efforts to link this process
to the microorganisms that mediate it are surprisingly limited. In particular, ammonia …

… Sediment and water samples were collected from San Francisco Bay in northern California
during the summers of 2004–2006 in conjunction with the Regional Monitoring Program (…

… It was shown that, in the absence of other noncovalent contacts, a single sugar–aromatic
interaction may modulate protein folding with a magnitude of ca. −0.8 kcal/mol. Fittingly, …

A combination of stable isotope and molecular biological approaches was used to determine
the activity, abundance and diversity of nitrifying organisms in the central California Current…

Multiple cropping (or mixed cropping), now being studied by scientists, has been used by
farmers for centuries. Multiple cropping systems were the first types of organized agriculture. …

… The included phylogenetic tree is based on a ca. 500-bp region of the dsrA gene to allow
for inclusion of the nearest neighbors in final alignments, which were based solely on the α …
