“…This low estimate of growth activity agrees with results of other assays on salt marsh sediment. Calculations based on the work of Christian et al (6) and the modelling efforts of Wiegert et al (14) suggest that the realized generation time of micro-organisms in the sediments is of the order of 50-60 days. While this community maintained a high standing stock of organ- Proc.…”

“…Sediment cores were taken from two biologically and physically distinct zones in the intertidal Spartina alterniflora salt marsh at Sapelo Island, Georgia. The material was screened through a 1 mm nylon mesh to eliminate macro-organic matter, particularly the living and dead roots of S. alterniflora (6). The screened samples were immediately extracted, processed by the method of Christian et al (6) (8).…”

Measurement of the adenylate energy charge ratio is proposed as a means of determining the growth state of natural microbial communities and the effect of environmental changes on them. Observations on microbial cultures and on natural microbial populations from the Western North Atlantic Ocean water and from sediments of a coastal salt marsh show that energy charge measurements do show the metabolic state of communities as well as species populations.

“…Consequently our measurements involve the sediments. From measurements of total ATP in the sediments (ATP is a measure of viable bacterial mass), the richest area is in the uppermost centimeter, which contains 5 to 10 times the microbial mass of deeper layers (Christian et al, 1975). It was previously thought that the Desulphovibrio organsms required strict anaerobiosis for viability, but studies by Sand et al (1975) have shown that exposure to air for as long as two hours will not decrease their viability.…”

. 2017. Maintenance of salt barrens inhibited landward invasion of Spartina species in salt marshes. Ecosphere 8(10):e01982. 10. 1002/ecs2.1982 Abstract. Spartina spp. (cordgrasses) often dominates intertidal mudflats and/or low marshes. The landward invasion of these species was typically thought to be restrained by low tidal inundation frequencies and interspecific competition. We noticed that the reported soil salinity levels in some salt marshes were much higher than those at the mean higher high water level, which might inhibit the landward invasion of cordgrass. To test this possibility, we transplanted Spartina alterniflora across an elevational gradient in an invaded salt marsh in the Yellow River Delta National Nature Reserve, where a salt accumulation zone (i.e., salt barren) was previously observed. We found that S. alterniflora was significantly inhibited by the salt barren in high marsh regions, although it performed better at upland and low marsh regions. A common garden experiment further elucidated that S. alterniflora performed best at low salinity levels and that this species is less sensitive to inundation frequency. Our results indicated that the salt barren inhibited the landward invasion of S. alterniflora in salt marshes and provided a natural barrier to protect the upland from invasion. Though field observations suggest that S. alterniflora could propagate along tidal channels, which provide low-salinity corridors for the dispersal of propagules, natural salt barrens can inhibit the landward invasion of Spartina in salt marshes. However, artificial disturbances that break the salt barren band in salt marshes (e.g., artificial ditches) might accelerate the invasion of Spartina spp. This new finding should alert salt marsh managers to pay attention to artificial ditches and/or other human activities when attempting to control Spartina invasion.
