The role of standing dead Spartina alterniflora and benthic microalgae in salt marsh food webs: considerations based on multiple stable isotope analysis
TL;DR: In this article, the stable isotope compositions (C, N, and S) of hve, senescent, and standing dead Spartina alterniflora were compared in order to determine the effects of aerial decomposition on the isotopic signature of aboveground S. alternjflora entering the food chain, which indicated that N2fixing microorganisms associdated with microalgal communities were an important source of N to salt marsh consumers.

Links between epibenthic community patterns and habitat characteristics in the Parila lagoon (Croatia)
Ivana Prusina,Tatjana Dobroslavić,Luka Glamuzina,Alexis Conides,Danijela Bogner,Slavica Matijević,Branko Glamuzina +6 more
TL;DR: The ecological analysis showed that total phosphorus concentration, temperature and salinity were the main environmental parameters affecting community structure of the Parila lagoon, and six species listed as frequent have a potential to be used as indicators of habitat quality.

The effect of biogenic irrigation intensity and solute exchange on diagenetic reaction rates in marine sediments
TL;DR: In this paper, the authors demonstrate a regular and strong dependence of anaerobic remineralization on diffusive transport and demonstrate that relative decreases in the uptake of solutes into biomass, abiogenic precipitation reactions, and increased removal of inhibiting metabolites all occur simultaneously.

Carbon isotopic fractionation in heterotrophic microbial metabolism.
TL;DR: Differences in the natural-abundance carbon stable isotopic compositions between products from aerobic cultures of Escherichia coli K-12 were measured and indicated significant isotopic heterogeneity in intracellular components.

Shallow water as a refuge habitat for fish and crustaceans in non-vegetated estuaries: an example from Chesapeake Bay
TL;DR: Since the recent demise of SAV in Chesapeake Bay, the results indicate many small species have shifted their distributions and now utilize primarily shallow water as an alternate refuge habitat.

Food web analysis of southern California coastal wetlands using multiple stable isotopes
Thomas J. Kwak,Joy B. Zedler +1 more
TL;DR: The demonstration of a salt marsh–channel linkage in these systems affirms that these habitats should be managed as a single ecosystem and that the restoration of intertidal marshes for endangered birds and other biota is compatible with enhancement of coastal fish populations.

Bioavailability of DON from natural and anthropogenic sources to estuarine plankton
TL;DR: In this paper, the authors examined the utilization of dissolved organic nitrogen (DON) from natural (forests) and anthropogenic (animal pastures, urban/suburban storm water runoff) sources (three sites per source) by estuarine plankton communities.
