It is generally considered that nitrogen availability is one of the major factors regulating
primary production in temperate coastal marine environments. Coastal regions often receive …

“Buffer capacities” has been defined in ecology as a holistic concept (eg, Integration of
Ecosystem Theories: A Pattern, second ed. Kluwer, Dordrecht, 1997, 388pp), but we show …

The rhizosphere sediments of seagrasses are generally a site of intense nitrogen fixation
activity and this can provide a significant source of “new” nitrogen for the growth of the …

A literature review of the effects of the reducing conditions of the sediment on seagrass
metabolism, growth and survival, and of the morphological and physiological adaptations …

We present the seasonal carbon (C) balance of the Mediterranean seagrass Posidonia
oceanica (L.) Delile calculated from seasonal rates of C gain (photosynthesis), C loss …

Rates of denitrification, N-fixation, gross community primary productivity, inorganic-N and
oxygen fluxes were determined in February, May and October 1997 in an intertidal Zostera …

Sulphate reduction rates (SRR) and nitrogen fixation rates (NFR) associated with isolated
roots, rhizomes and sediment from the rhizosphere of the marine macrophytes Zostera noltii …

Decomposition and distribution of root exudates of Zea mays L. were studied by means of 14
CO 2 pulse labeling of shoots on a loamy Haplic Luvisol. Plants were grown in two …

The ability of rhizosphere diazotrophs to remain competitive during increased nitrogen
availability in situ was tested in a salt marsh grass stand. Nitrogen (16.3 g m-2) or nitrogen …

The effect of the seagrass Zostera capricorni on sediment microbial processes was studied
in a tank experiment, where vegetated and unvegetated control sediments were incubated …
