this research is focused on facies distribution, palaeoecology and palaeoenvironment of the gurimember of the mishan formation in kuh-e shur and kuh-e kurdeh sections at the lar area, fars province.the guri member is composed of limestone, marly limestone and marl and the thickness at kuh-e shur andkuh-e kurdeh is about 72 and 110 meters, respectively. based on petrographical studies of 120 thi...

[Dr. Fontanier’s comment] The paper entitled “Variation in stable carbon and oxygen isotopes of individual benthic foraminifera: tracers for quantifying the vital effect” by Ishimura San et al. deals with the applicability of inter-individual delta13C and delta18O distributions (Standard Deviation within species) to reconstruct the bottom water isotopic signatures. This work is based on live an...

[1] We explore the applicability of paired Mg/Ca and O/O measurements on benthic foraminifera from Southern Ocean site 747 to paleoceanographic reconstructions on pre-Pleistocene timescales. We focus on the late Oligocene through Pleistocene (27–0 Ma) history of paleotemperatures and the evolution of the dO values of seawater (dOsw) at a temporal resolution of 100–200 kyr. Absolute paleotempera...

[1] The carbon isotope ratio (dC) of plant material is commonly used to reconstruct the relative distribution of C3 and C4 plants in ancient ecosystems. However, such estimates depend on the d C of atmospheric CO2 (dCCO2) at the time, which likely varied throughout Earth history. For this study, we use benthic and planktonic dC and dO records to reconstruct a long‐term record of Cenozoic dCCO2....

A robust and consistent taxonomy underpins the use of fossil material in palaeoenvironmental research and long-term assessment of biodiversity. This study presents a new integrated taxonomic protocol for benthic foraminifera by unequivocally reconciling the traditional taxonomic name to a specific genetic type. To implement this protocol, a fragment of the small subunit ribosomal RNA (SSU rRNA)...

Large benthic foraminifera (LBF) are important for reef sediment formation, but sensitive to elevated temperature and nutrients. However, it is possible that conspecific foraminifera living in different reef sites present divergent response to environmental shifts. We investigated how populations of Amphistegina lobifera from reef sites located along a temperature and nutrient gradient of the n...

the qom formation in southwest kashan in sanandaj-sirjan fore arc basin has a thickness of 190 meters and is composed of medium to thick and massive bedded limestone, marly limestone, sandy limestone, marl and coglomerates. study of these deposits led to recognition of nine microfacies related to a carbonate platform. the high presence of perforate foraminifera in most of the recognized microfa...

This Paper reports a study on the benthic faunal abundance and diversity of tiger shrimp P. monodon culture ponds in Perak, west coast of Malaysia Peninsular. Sampling was carried out at three weeks interval throughout the 116 days culture period. In addition, water temperature, dissolved oxygen, salinity, transparency, pH and organic matter of soil were also measured. Results showed that the m...
