Morphological abnormalities in benthic foraminifers of the Antalya coast

2019
Many researchers report abnormal test morphologies in benthic foraminifers and some suggest that anthropogenic pollution may be one of the causes for these anomalies. Some species are even used as bioindicators of anthropogenic pollution. However, environmental stress may be exerted by natural factors also, such as hypersalinity, periodical ...

Benthic Foraminifers From Eastern Gulf of Alaska: ABSTRACT

AAPG Bulletin, 1980
Grab samples, dart cores, and gravity cores from the Gulf of Alaska between Montague Island and Yakutat Bay were analyzed for benthic foraminifers. Robust specimens of Cassidulina californica, C. limbata, and Cibicides lobatulus are abundant in coarse sediment on Tarr Bank, Middleton Island platform, and along much of the outer shelf east of Kayak ...

Twin embryos in the larger benthic foraminifer Nephrolepidina praemarginata

2015
Twin embryos were recovered in Nephrolepidina praemarginata populations from the upper Rupelian of the Caltavuturo Formation (Sicily). Biometric data and photographic evidences suggest that Siamese-twins embryos result from joined cells produced from the same reproductive cyst during the multiple fissions. The fusion of juveniles may occur before the

Alkalization of seawater enhances calcification of large benthic foraminifers.

There is concern that the increasing pCO2 following the Industrial Revolution Period might lead to ocean acidification, which could affect calcifying organisms in the oceans. Recently, negative emission technology has been attracting attention as an effective countermeasure for greenhouse gas emissions.
