... not be the only factor controlling coiling direction. Fossil populations of Neogloboquadrina pachyderma and G . bulloides studied by them display enhanced flux of the sinistral morphotypes during intensive upwelling conditions and, thus, the nutrient level seems to play an important role ( Little et al...

...Michal Kucera; James P. Kennett Abstract Switches in coiling direction of shells of the planktonic foraminifer Neogloboquadrina pachyderma have been extensively used as a paleotemperature proxy from the late Miocene through the Quaternary, exploiting the specific modern polar affinity...

... preference toward one direction of coiling or have different coiling directions in different hydrographic or biogeographic settings. For example, the sinistral populations of the foraminifer Neogloboquadrina pachyderma (Ehrenberg) are abundant in both the Arctic and Antarctic Oceans, whereas populations...

... was associated with higher standing stocks in near surface waters, including high abundances of Globigerinita glutinata and Neogloboquadrina dutertrei . Globorotalia truncatulinoides mainly lives close to the seasonal pycnocline and can be linked to winter conditions indicated by lower sea-surface temperatures...

.... The taxonomy follows the World Register of Marine Species (WoRMS: http://www.marinespecies.org/index.php ; accessed on 27.05.2016). Following Darling et al. (2006) , the cooling direction is considered for the separation of Neogloboquadrina incompta from Neogloboquadrina pachyderma . The SST...

..., Globoturborotalita decoraperta , is not well understood. The first appearance of Neogloboquadrina pachyderma ( sensu Darling et al. 2006 ) is associated with the second-largest uncertainty. At present, N. pachyderma and N. incompta can be best differentiated by their opposite coiling directions...
