Shallow-water benthic foraminifera as proxy for natural versus human-induced environmental change [PDF]

open access: yes, 2007
Ecosystem composition and functioning is not only subjected to human-induced alterations, ecosystems also subjected to natural (e.g. climate-induced) variability.

Dual clumped isotopes in foraminiferal calcite reveal kinetic bias in some species

open access: yesCommunications Earth & Environment
Clumped isotope (∆47) analyses of foraminifera provide a powerful means to reconstruct upper and bottom water temperatures, independent of seawater δ18O and elemental composition.

Sedimentation environment of the Cojimar Formation (Havana province) based on benthic foraminifera

open access: yesMinería y Geología, 2022
Cojímar Formation, —Lower Miocene (upper part) to Middle Miocene (lower part)—, is a unit in Western Cuba well known for its extensive development and exposure outcrops. It has been widely used in bioestratigraphic studies.

Study of current benthic foraminifera as environmental bioindicators in the mediterranean coasts, northwest Morocco [PDF]

open access: yesE3S Web of Conferences
In this project, we introduce a novel methodology for analysing the environmental conditions in the coastal area of Martil (Tétouan, Morocco) using benthic foraminifera as bio-indicators of marine ecological status.

Cytological Observations of the Large Symbiotic Foraminifer Amphisorus kudakajimensis Using Calcein Acetoxymethyl Ester. [PDF]

open access: yesPLoS ONE, 2016
Large benthic foraminifera are unicellular calcifying reef organisms that can form symbiotic relationships with a range of different microalgae.

Early to middle Miocene foraminifera from the deep-sea Congo Fan, offshore Angola [PDF]

open access: yes, 2008
Analysis of a 630m section of an exploration well penetrating the distal part of the Congo Fan (~2000m water depth) yielded high abundance and diversity assemblages of agglutinated and calcareous benthic foraminifera.

Oxygen as a control on seafloor biological communities and their roles in sedimentary carbon cycling [PDF]

open access: yes, 2007
13C tracer experiments were conducted at sites spanning the steep oxygen, organic matter, and biological community gradients across the Arabian Sea oxygen minimum zone, in order to quantify the role that benthic fauna play in the short-term processing of

Ecological significance of benthic foraminifera: 13C labelling experiments [PDF]

open access: yesMarine Ecology Progress Series, 2000
We examined the ability of foraminifera in taking up freshly deposited algal carbon in intertidal estuarine sediments. Lyophylized C-13-labelled axenic Chlorella was added to intact sediment cores containing natural benthic biota. The response of the system as a whole was rapid; similar to 5% of the added carbon was respired to CO2 within 6 h. Bacteria

Response of deep-water agglutinated foraminifera to dysoxic conditions in the California Borderland basins [PDF]

open access: yes, 1995
Analysis of agglutinated benthic foraminifera from surface samples collected in the San Pedro and Santa Catalina Basins reveals a predictable relationship between the proportions of morphogroups with decreasing bottom water oxygen levels and with the ...
