Ecology of Benthic Foraminifera

Notes for a Short Course: Studies in Geology, 1982
Benthic foraminifera live in a wide variety of marine habitats, from marshes to abyssal plains. Both epifaunal and infaunal adaptations are present. The distribution of species is controlled by a complex of abiotic and biotic variables of the environment, usually resulting in a depth-zonation of assemblages on continental margins.The composition of the

Benthic behavior of planktic foraminifera

Geology, 1996
In culture containers with sediment on the bottom, two of six species of planktic foraminifera reveal characteristic benthic activities, such as reorientation, crawling, and burrowing. Globigerinella siphonifera creates well-organized burrows and excavated sediment on a circular pile.

Biogeography of Modern Benthic Foraminifera

Notes for a Short Course: Studies in Geology, 1982
Biogeography is concerned with recording and explaining the distribution of organisms in space and time. In their search for patterns of distribution, biogeographers have classified the surface of the earth into a hierarchical scheme of ecological units (e.g. Kauffman and Scott, 1976). The basic biogeographic units are realms and provinces.

Pleistocene Benthic Foraminifera and DeepM

Journal Geological Society of India, 1991
Abstract The evolution of Pleistocene deep-sea environments at Northern Indian Ocean DSDP Site 219 has been evaluated, using the quantitative analyses of deep-sea benthic foraminiferal fauna. The Pleistocene assemblages are dominated by Uvigerina proboscidea which shows remarkable frequency changes.

Biogeography of neritic benthic Foraminifera

1999
Large-scale biogeographic distributions of benthic Foraminifera of the world’s shelves exhibit a pattern that indicates a major controlling role for temperature at this scale. Cold-, temperate-, and warm-water groupings of provinces have been recognized around the world, with a greater number of provinces delineated in warmer regions. Modern provincial

Benthic Foraminifera: Response to Environment

1984
As pointed out in the previous chapter, the response of each benthic species to the abiotic and biotic conditions in its environment is a specific one, reflected by its particular life history. An attempt is made in the following to summarize and integrate in situ observations, experimental evidence and assumptions based on circumstantial evidence ...

Benthic foraminifera assemblages at Great Meteor Seamount

Marine Biology, 2004
Foraminiferal assemblages found at Great Meteor Seamount were studied in August 1998. Communities of living foraminifera in surface sediments from the plateau (290–325 m water depth) and from the surrounding base (2,300–4,096 m) were compared in abundances, diversity, and species composition.
