Large benthic Foraminifera (LBF) are major carbonate producers on coral reefs, and are hosts to a diverse symbiotic microbial community. During warm episodes in the geological past, these reef-building organisms expanded their geographical ranges as subtropical and tropical belts moved into higher latitudes. During these range-expansion periods, LBF were the most prolific carbonate producers on reefs, dominating shallow carbonate platforms over reef-building corals. Even though the fossil and modern distributions of groups of species that harbour different types of symbionts are known, the nature, mechanisms, and factors that influence their occurrence remain elusive. Furthermore, the presence of a diverse and persistent bacterial community has only recently gained attention. We examined recent advances in molecular identification of prokaryotic (i.e. bacteria) and eukaryotic (i.e. microalgae) associates, and palaeoecology, and place the partnership with bacteria and algae in the context of climate change. In critically reviewing the available fossil and modern data on symbiosis, we reveal a crucial role of microalgae in the response of LBF to ocean warming, and their capacity to colonise a variety of habitats, across both latitudes and broad depth ranges. Symbiont identity is a key factor enabling LBF to expand their geographic ranges when the sea-surface temperature increases. Our analyses showed that over the past 66 million years (My), diatom-bearing species were dominant in reef environments. The modern record shows that these species display a stable, persistent eukaryotic assemblage across their geographic distribution range, and are less dependent on symbiotic photosynthesis for survival. By contrast, dinoflagellate and chlorophytic species, which show a provincial distribution, tend to have a more flexible eukaryotic community throughout their range. This group is more dependent on their symbionts, and flexibility in their symbiosis is likely to be the driving force behind their evolutionary history, as they form a monophyletic group originating from a rhodophyte-bearing ancestor. The study of bacterial assemblages, while still in its infancy, is a promising field of study. Bacterial communities are likely to be shaped by the local environment, although a core bacterial microbiome is found in species with global distributions. Cryptic speciation is also an important factor that must be taken into consideration. As global warming intensifies, genetic divergence in hosts in addition to the range of flexibility/specificity within host-symbiont associations will be important elements in the continued evolutionary success of LBF species in a wide range of environments. Based on fossil and modern data, we conclude that the microbiome, which includes both algal and bacterial partners, is a key factor influencing the evolution of LBF. As a result, the microbiome assists LBF in colonising a wide range of habitats, and allowed them to become the most important calcifiers on shallow platforms worldwide during perio...

Sea sonal vari a tions, en vi ron men tal pa ram e ters and stand ing crop as sess ment of ben thic foraminifera in east ern Bah rain, Ara bian Gulf Liv ing ben thic foraminifera in a rel a tively un pol luted site off shore Bah rain in the Ara bian Gulf, were stud ied to de ter mine the sea sonal vari abil ity of their pop u la tions, as well as en vi ron men tal pa ram e ters that may af fect their dis tri bu tion. The max i mum foraminiferal den sity was ob served dur ing win ter with the as sem blages pri mar ily dom i nated by rotaliids and sec ond arily by miliolids. The high pop u la tion is at trib uted to an in creased num ber of ju ve niles. A re la tion ship be tween sed i ment grain-size and the foraminiferal den sity re veals that ju ve niles were most abun dant on coarse-grained sandy sub strate and less abundant on fine-grained sub strates. In spring, the foraminiferal den sity de creased, and the low est val ues were ob served dur ing sum mer. The pop u la tion in creased again in au tumn with high est ju ve nile/adult ra tios. More over, re sults of rel a tive abundance and spe cies con sis tency show that Am mo nia and Glabratellina are con sis tent from the shal low est to the deep est station, whereas miliolids oc curred only at deeper sta tions. The num bers of Peneroplidae and Elphidium also in creased along the depth transect. En vi ron men tal char ac ter iza tion re veals that al though the site is sub ject to eutrophication caused by nitrates and sul fates, pol lu tion caused by hy dro car bons and heavy met als is not sig nif i cant. The as sess ment of 63 heavy metals showed that none of the met als had con cen tra tions that ex ceed in ter na tion ally ac cepted norms (the de vised level of Ef fect Range -Low), but with high con cen tra tion of stron tium. The lack of a sig nif i cant en vi ron men tal ef fect of heavy met als is con firmed by the Foraminiferal Ab nor mal ity In dex of <2%. Like wise, no hy dro car bon con tam i na tion was de tected in the wa ter or sed i ment sam ples. We con clude that the site in Bah rain is not yet ad versely af fected by hu man de vel op ment, and there fore can pro vide base line in for ma tion for fu ture com par i son and as sess ment of foraminiferal as sem blages in con tam inated zones of the Ara bian Gulf.

“…These taxa were represented by four orders and suborders, Textulariida, Lagenida, Rotaliida and Miliolida, with the latter represented by 40 species (22 in Figure 1). Modern and relict benthic foraminiferal biofacies along a carbonate ramp transect were studied in the southern part of Kuwait [58]. In this study, a total of 141 benthic foraminiferal taxa were identified, a figure that is much higher compared to previous studies (23 in Figure 1).…”

Modern Benthic Foraminiferal Diversity: An Initial Insight into the Total Foraminiferal Diversity along the Kuwait Coastal Water

Kuwait territorial water hosts an important part of national biodiversity (i.e., zooplankton and phytoplankton), but very limited information exists on the overall diversity of benthic foraminifera. On the basis of the integration of publications, reports and theses with new available data from the Kuwait Bay and the northern islands, this study infers the total benthic foraminiferal diversity within Kuwait territorial water. This new literature survey documents the presence of 451 species belonging to 156 genera, 64 families, 31 superfamilies and 9 orders. These values are relatively high in consideration of the limited extension and the shallow depth of the Kuwait territorial water. Kuwait waters offer a variety of different environments and sub-environments (low salinity/muddy areas in the northern part, embayment, rocky tidal flats, coral reef systems, islands and shelf slope) that all together host largely diversified benthic foraminiferal communities. These figures are herein considered as underestimated because of the grouping of unassigned species due to the lack of reference collections and materials, as well as the neglection of the soft-shell monothalamids (‘allogromiids’).
