Oxygen Metabolic Responses of Three Species of Large Benthic Foraminifers with Algal Symbionts to Temperature Stress

open access: yesPLoS ONE, 2014
Water temperature affects the physiology of large benthic foraminifers (LBFs) with algal symbionts dwelling in coral reef environments. However, the detailed physiological responses of LBF holobionts to temperature ranges occurring in their habitats are ...

SMALLER FORAMINIFERS FROM THE LOWER PERMIAN EMARAT FORMATION, EAST OF FIRUZKUH (CENTRAL ALBORZ, IRAN)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2016
The uppermost Carboniferous-Lower Permian Dorud Group of the Gaduk section in Central Alborz (Iran) is more than 44 m-thick; it includes thick succession of conglomerates, quartzarenites, calcareous sandstones, oncolitic fusulinid limestones, sandy ...

Seasonal and interannual variability in population dynamics of planktic foraminifers off Puerto Rico (Caribbean Sea) [PDF]

open access: yesJournal of Micropalaeontology, 2019
The state of a population of planktic foraminifers at a certain time reflects multiple processes in the upper ocean, including environmental conditions to which the population was exposed during its growth, the age of the cohorts, and spatiotemporal ...

Biotic Response to Rapid Environmental Changes During the Permian–Triassic Mass Extinction

open access: yesFrontiers in Marine Science, 2022
The divergent patterns of Permian–Triassic mass extinction (PTME) have been extensively documented in varying water depth settings. We here investigated fossil assemblages and sedimentary microfacies on high-resolution samples from two adjacent sections ...

Microfossils and brachiopods from the Lower Barremian at Prekonozi, eastern Serbia [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2005
This paper presents the results of an integral biostratigraphical study based on orbitolinids and other benthic foraminifers, brachiopods and algae of a part of the Prekonozi section, eastern Serbia.

Effect of different seawater Mg2 + concentrations on calcification in two benthic foraminifers

open access: yesMarine Micropaleontology, 2014
Magnesium, incorporated in foraminiferal calcite (Mg/CaCC), is used intensively to reconstruct past seawater temperatures but, in addition to temperature, the Mg/CaCC of foraminiferal tests also depends on the ratio of Mg and Ca in seawater (Mg/CaSW ...

Marsh development and sea level changes in the Gernika Estuary (southern Bay of Biscay): foraminifers as tidal indicators

open access: yesScientia Marina, 2006
The ecological distribution of some species of Foraminifera living in estuaries can be used in the interpretation of former coastal lines. There is a close relationship between tide level and the distribution of particular benthic foraminifer species.

Devonian-Carboniferous boundary beds in the Vorkuta transverse uplift (Bolshaya Usa River)

open access: yesУчёные записки Казанского университета: Серия Естественные науки, 2018
The paper contains multidisciplinary data on the lithology and palaeontology of the Devonian–Carboniferous boundary beds in the shallow-water facies in the Bolshaya Usa River section (Vorkuta Uplift). A recent discussion on the position and marker of the

The correlation of the Neogene of Central and Eastern Paratethys segments of Ukraine with the International Stratigraphic Chart based on planktonic microfossils

open access: yesGeologica Carpathica, 2015
Detailed analysis of microplankton occurrence (planktonic foraminifera, nannoplankton, dinocysts) in Neogene sediments situated at the north-western and south-eastern margins of Ukraine enabled us to distinguish 10 associations of oceanic plankton which ...

Cenomanian – Coniacian zonation (foraminifers and calcareous algae) in the Guerrero – Morelos basin, southern Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
A biostratigraphic zonation of the Cenomanian–Coniacian rocks of the Guerrero–Morelos basin (southern Mexico) is proposed. The stratigraphic distribution of 70 species of calcareous algae and benthic and planktonic foraminifers is used to characterize ...
