The results suggest that the diverse strains arose by transfer of chromosomal symbiotic genes from ICMP3153 to nonsymbiotic rhizobia in the environment.

The impact of suspended mussel culture on the benthos of a small Nova Scotia cove was assessed using meehods involving both benthic metabolism and community structure, and there is a shift toward anaerobic metabolism at the mussel lines, the impact of mussels falling to the sediments was more noticeable in benthics community structure than was any impact due to organic sedimentation or hypoxia.

Onset of recent rapid sea-level rise in the western Atlantic Ocean
Postglacial sea-level rise and sedimentary response in the Guadiana Estuary, Portugal/Spain border
Living vs. total foraminiferal populations; their relative usefulness in paleoecology
Investigation of living and total assemblages over a three year period in a Nova Scotia salt marsh indicates that consideration of total associations more accurately depicts modern environments and is, therefore, more useful to most paleoenvironmental studies.

The persistence of the warm, nutrient-rich regime since the early 1970s is largely unique in the context of the last approximately 1,800 yr and is concluded that nutrient variability in this region is coordinated with recent changes in global climate.
Records of prehistoric hurricanes on the South Carolina coast based on micropaleontological and sedimentological evidence, with comparison to other Atlantic Coast records
Singleton Swash on the South Carolina coast provides an extended record of storm events for this coast. We used experience gained by looking at storm traces detected as layers of offshore…

It becomes clear that there are many individual trends, especially with shell ornamentation, but few broad ones, and that it is almost impossible, with exception of some of the larger reef-dwelling, symbiont-bearing foraminifera, to predict how any species will react to various parameters.
