“…The foraminifer assemblages show clear differences between older and younger parts of the Holocene. The warmest surface-water temperatures, as indicated by high relative abundances of Pulleniatina obliquiloculata and G. menardii [20], occurred at about 5 ka, which is consistent with the results of Brunner (1982) [7]. [21] summarized census data on foraminifer assemblages in several cores from the western and northern GOM, spanning most of the Holocene, and concluded that the relative abundance of the G. sacculifer in GOM foraminiferal assemblages is a reliable proxy for changes in the average position of the ITCZ.…”

“…Malmgren and Kennett [16] used principal component analysis of foraminiferal-assemblage data from a series of cores in the western GOM to develop qualitative estimates of SST changes through the Holocene. Brunner [7] used the transfer function technique of Imbrie and Kipp [17] to estimate SSTs and salinities extending back through the last interglacial in several cores from the GOM. The sampling strategy of Brunner [7] was designed to establish the glacial-interglacial signal and includes only a few SST estimates for the Holocene.…”

Marine records from the northern Gulf of Mexico indicate that significant multidecadal-and century-scale variability was common during the Holocene. Mean annual sea-surface temperature (SST) during the last 1,400 years may have varied by 3 o C, and excursions to cold SST coincide with reductions in solar output. Broad trends in Holocene terrestrial climate and environmental change along the eastern portion of the northern Gulf Coast are evident from existing pollen records, but the high-frequency details of climate variability are not well known. Continuous and well-dated records of climate change and climate variability in the western portion of the northern Gulf Coast are essentially lacking.Information on Holocene floods, droughts, and storm frequency along the northern Gulf Coast is limited. Records of floods may be preserved in continental shelf sediments, but establishing continuity and chronologies for sedimentary sequences on the shelf presents challenges due to sediment remobilization and redeposition during storms. Studies of past storm deposits in coastal lakes and marshes show promise for constructing records of past storm frequency. A recent summary of sea-level history of the northern Gulf Coast indicates sea level was higher than modern sea level several times during the last few thousand years.

Additional information regarding methodology can be found in Imbrie &Kipp (1971), Brunner andCooley (1976), Brunner (1979Brunner ( , 1982, and Dowsett & Poore (2001). Careful attention was paid to the taxonomic concepts of the various authors so that the resulting data set is internally taxonomically-consistent.…”

Patterns of genetic variation reflect interactions among microevolutionary forces that vary in strength with changing demography. Here, patterns of variation within and among samples of the mouthbrooding gafftopsail catfish (Bagre marinus, Family Ariidae) captured in the U.S. Atlantic and throughout the Gulf of Mexico were analyzed using genomics to generate neutral and non‐neutral SNP data sets. Because genomic resources are lacking for ariids, linkage disequilibrium network analysis was used to examine patterns of putatively adaptive variation. Finally, historical demographic parameters were estimated from site frequency spectra. The results show four differentiated groups, corresponding to the (1) U.S. Atlantic, and the (2) northeastern, (3) northwestern, and (4) southern Gulf of Mexico. The non‐neutral data presented two contrasting signals of structure, one due to increases in diversity moving west to east and north to south, and another to increased heterozygosity in the Atlantic. Demographic analysis suggested that recently reduced long‐term effective population size in the Atlantic is likely an important driver of patterns of genetic variation and is consistent with a known reduction in population size potentially due to an epizootic. Overall, patterns of genetic variation resemble that of other fishes that use the same estuarine habitats as nurseries, regardless of the presence/absence of a larval phase, supporting the idea that adult/juvenile behavior and habitat are important predictors of contemporary patterns of genetic structure.
