The classification of foraminifera has been largely constructed on the basis of shell morphology, the nature of the wall, overall appearance, chamber arrangement, and specific morphological features, as pointed out in Loeblich and Tappan, 1988. In this volume John Murray investigates the ecological processes that control the distribution, abundance, and species diversity of benthic foraminifera in environments ranging from marsh to the deepest ocean. This evolutionary plasticity among early Foraminifera makes their present morphology-based classification of limited value. Foraminifera are commonly deﬁned as marine testate protists, and their diversity is mainly assessed on the basis of the morphology of their agglutinated or mineralized tests. The limitations of a traditional morphology-based classification of Foraminifera have been demonstrated by molecular phylogenetic studies for several years now. The morphology of foraminifera tests varies enormously, but in terms of classification two features are important. 108 0 obj <>stream The study of the planktonic foraminifera … Moreover, their tests Planktic foraminifera (often referred to as planktic forams) are classified primarily by the ultrastructure and morphology of their tests (shells).

Foraminifera are one of the most abundant groups in the lagoon of New Caledonia, as shown in the Compendium of marine species from New Caledonia (PAYRI & DE FORGES, eds, 1987): foraminifera (6%), algae (5%), molluscs (23%), arthropods (22%) and vertebrates dominated by fish (19%). To interpret the fossil record it is necessary to have an understanding of the ecology of modern foraminifera and the processes operating after death leading to burial and fossilisation. Together, this indicates that morphological heritability may be low across Foraminifera or at least in taxa exposed to a high degree of environmental instability such as planktic and shallow-living benthic foraminifera. Environmental conditions such as temperature and trace elements may play an important role in stimulating such unusual test occurrences. foraminifera were recognized by Dujardin as protozoa, and shortly afterwards, d’Orbigny produced the first classification of foraminifera, which was based on test morphology.
