Intraspecific stable isotope variability in the planktic foraminifera Globigerinoides sacculifer: Results from laboratory experiments
Laboratory experiments conducted on the multichambered planktic foraminifera Globigerinoides sacculifer are used to determine the effect of symbiont photosynthesis on shell carbon and oxygen isotopic composition. Stable isotope analyses of individual chambers secreted under controlled temperature and light levels show that chamber jl3C values increase with increasing light levels. The effect of...
متن کاملPartial collapse of the marine carbon pump after the Cretaceous-Paleogene boundary
The impact of an asteroid at the end of the Cretaceous caused mass extinctions in the oceans. A rapid collapse in surface to deepocean carbon isotope gradients suggests that transfer of organic matter to the deep sea via the biological pump was severely perturbed. However, this view has been challenged by the survival of deep-sea benthic organisms dependent on surface-derived food and uncertain...
متن کاملEmendation of the Genus Streptochilus Broennimann and Resig, 1971 (Foraminifera) and New Species from the Lower Miocene of the Atlantic and Indian Oceans
Three new species of Streptochilus, a biserial planktic foraminiferal genus, were recognized in the lower Miocene of the eastern Atlantic and western Indian Oceans. These species had been formerly thought to be benthic species of the genus Bolivina, but evidence on their apertural morphology and stable isotopic composition indicates that they lived as plankton and should be assigned to the genu...
متن کاملOcean currents generate large footprints in marine palaeoclimate proxies.
Fossils of marine microorganisms such as planktic foraminifera are among the cornerstones of palaeoclimatological studies. It is often assumed that the proxies derived from their shells represent ocean conditions above the location where they were deposited. Planktic foraminifera, however, are carried by ocean currents and, depending on the life traits of the species, potentially incorporate di...
متن کاملSurviving mass extinction by bridging the benthic/planktic divide.
Evolution of planktic organisms from benthic ancestors is commonly thought to represent unidirectional expansion into new ecological domains, possibly only once per clade. For foraminifera, this evolutionary expansion occurred in the Early-Middle Jurassic, and all living and extinct planktic foraminifera have been placed within 1 clade, the Suborder Globigerinina. The subsequent radiation of pl...
