“…Individual foraminifera were dry picked using a fine paint brush and placed onto micropalaeontological slides. The foraminifera were identified, in the first instance, using Tappan, 1987, 1964) and identified to species level, where possible, using Bandy (1961Bandy ( , 1953, Brenner (1962), McGann (2002) and Lesen (2005). The smallest split fraction was examined first.…”

Extensive CO2 vents have been discovered in the Wagner Basin, northern Gulf of California, where they create large areas with lowered seawater pH. Such areas are suitable for investigations of long-term biological effects of ocean acidification and effects of CO2 leakage from subsea carbon capture storage. Here, we show responses of benthic foraminifera to seawater pH gradients at 74-207m water depth. Living (rose Bengal stained) benthic foraminifera included Nonionella basispinata, Epistominella bradyana and Bulimina marginata. Studies on foraminifera at CO2 vents in the Mediterranean and off Papua New Guinea have shown dramatic long-term effects of acidified seawater. We found living calcareous benthic foraminifera in low pH conditions in the northern Gulf of California, although there was an impoverished species assemblage and evidence of post-mortem test dissolution.

“…Although most records are from sediment samples it is also found to be epiphytal in low abundance on various calcareous algae on nevis (Wilson, 2007;Wilson & Ramsook, 2007). The areas of high abundance are: San Francisco Bay, California, USA (Lesen, 2005), nW Gulf of Mexico (Phleger, 1951;1956) and Puerto Rico (Seiglie, 1974). San Francisco Bay is an estuary with turbid water which is of normal salinity in the summer but diluted by runoff during the winter and spring (annual range of salinity 15-32).…”

“…The standing crop of F. pontoni collected monthly over two years ranged from 0 to 304 per 10 cm 3 sediment and was positively correlated with sediment ToC, nitrogen, amino acids and chlorophyll-a but not with sediment bacteria. Lesen (2005) suggests that measurement of as many potential food resources as possible is necessary to fully evaluate the food supply. The shelf and upper slope in the nW Gulf of Mexico have salinities of 35.5-36, temperatures of ~10-20°C but no records were made of potential food supply.…”

Living benthic foraminifera: biogeographical distributions and the significance of rare morphospecies

Abstract. Previous studies have investigated regional distribution but this is the first attempt to investigate the global biogeographical distribution of individual morphospecies of living/stained smaller benthic foraminifera. From 8032 samples collected between 1952 and 2011 data have been gathered on the relative abundance of >120 species in five major environments ranging from marsh to deep sea. There is a spectrum of six groups of species with abundance ranging from very high (Group 1) to extremely low (Group 6). In the latter species abundance never reaches 10% of an assemblage and, in many cases, it is only 1–2%. Individual species are shown to occupy a range of environments with very few being confined to a single environment (usually either marsh or deep sea). Some species occur in several oceans while others are confined to just one. There is no correlation between species abundance and being either widely or narrowly distributed. Propagules are the most likely mechanism of dispersal but some narrowly distributed species may not produce them. Generalists may be widely or narrowly distributed but opportunists are likely to be widely distributed. The rare species of Group 6 contribute to high diversity in shelf and deep-sea assemblages. These species may be adapted to minor differences in microhabitats induced by disturbance and patchy food supply. Patterns of biogeography have application to ecology, palaeoecology and taxonomy.

Statistically significant differences (when p < 0.05 using the permutation t-test) among Live Foraminiferal Densities (LFDs) recovered in August, November, March and May were detected at tropical Caroni swamp, Claxton bay (Trinidad), temperate Cowpen marsh and Brancaster marsh (U.K.). The monthly mean LFDs of the foraminiferal metacommunities (all stations), assemblages (groups of stations defined by cluster analysis), and the agglutinated and calcareous specimens within each were compared separately. The LFDs of the Caroni swamp metacommunity did not fluctuate significantly among months, but significantly higher abundances of agglutinated specimens occurred in the upper assemblage in March; and calcareous specimens in the lower assemblage in November. At Claxton bay, monthly LFDs of the metacommunities and assemblages did not vary significantly, but calcareous and agglutinated species within each favoured dry (March and May) and wet (August and November) months respectively. At the temperate marshes, significantly higher LFDs of the metacommunities and assemblages were recorded in warmer months. August blooms of the Cowpen marsh metacommunity was attributed to agglutinated specimens in the upper assemblage, and calcareous specimens in the lower assemblage. May blooms of the Brancaster marsh upper assemblage were attributed to calcareous specimens, but there were no seasonal blooms of the lower assemblage.
