Happy #FossilFriday #ForamFriday everybody! This week's #ForamFact: Planktonic forams are migrating due to climate change...but will it be enough? A new study from Chabaane et al. (2024) documents that planktonic foraminifera are exhibiting vertical and latitudinal migration - as well as a huge reduction in abundance all around the world. Ocean warming and acidification due to anthropogenic climate is severely alterating their ecosystems, and in the low-latitudes in particular, by 2050 and 2100, physicochemical environments will surpass their ecological tolerances. You can learn more about these worrying observations here: Chaabane, S., de Garidel-Thoron, T., Meilland, J., Sulpis, O., Chalk, T.B., Brummer, G.J.A., Mortyn, P.G., Giraud, X., Howa, H., Casajus, N. and Kuroyanagi, A., 2024.

Happy #FossilFriday #ForamFriday everybody! This week's #ForamFact: Did you know about … The secondary ion mass spectrometry (SIMS) techniques applications on foraminifera? Since the analytical measurement of the oxygen and carbon isotope composition of foraminiferal tests was established in the late 1940s, multiple tests are pooled and analyzed, resulting in a single oxygen and carbon isotope value representing their mean composition. These records compiled by multi-test analysis provide, in most scenarios, a faithful picture of the Earth’s past climate. However, foraminiferal tests feature isotopic heterogeneity on micrometer scales and thus record a wealth of additional information that can be assessed by secondary ion mass spectrometry (SIMS) using spots of 10 μm or less. The study by Kozdon (2024) provides a history of in situ stable isotope measurements in foraminifer tests by SIMS, discusses landmark studies, and offers an outlook on future research.

Happy #FossilFriday #ForamFriday everybody! Did you know… Magnetic foraminifera thrive in the Mariana Trench? The hadal foraminifera?Resigella bilocularis?from the Mariana Trench (6,980–10,911 meters depth) contains magnetite crystals in its stercomata, enabling it to align with magnetic fields. This is the first record of a magnetic protist at such extreme depths, broadening our understanding of biomagnetism in Earth's extreme environments.

Happy #FossilFriday ?? This week’s #ForamFact: Did you know that benthic foraminifera can serve as bioindicators of methane seep activity? ?? In the southwestern Caribbean, species like Lobatula ungeriana thrive in methane-rich areas. ?? When seepage intensifies, foraminiferal abundance drops, and physiological adaptations become key for survival. ??

? ?? SPECIAL ISSUE ALERT ? The October issue of The Journal of Foraminiferal Research is focused on reviewing traditional applications and recent advances in #foraminiferal #geochemistry. ???? ???? ?? https://lnkd.in/d3-pMNXw The major theme of this special issue is advances and insights derived from single-test (See articles by Fehrenbacher et al., Lane et al., and Murray-Wallace et al.) and even intratest geochemical analyses (See articles by Hupp & Fehrenbacher and Kozdon). Revelations from such fine-scale data allow us to revisit old (and potentially outdated) assumptions, while revising methodologies to improve our interpretations of both new and published #geochemical #proxy records derived from #foraminifera. While the main topics being discussed are predominantly aimed at researchers with more of a micropaleontological background than a geochemical one, this issue also includes arguably the most important effort to consolidate and reconcile information regarding benthic foraminiferal taxonomy to date (See the article by Burkett et al.). We hope this issue may serve as both a resource and an inspiration for students, early career, and established scientists to explore new methods to answer burning questions across a range of fields of study. https://lnkd.in/d3-pMNXw #geochemistry #foraminifera #micropaleontology #geochemicalproxy

This ForamFact is a tribute to Prof Barun who always had a kind word, an interesting topic to start a conversation. An enthusiastic about forams and science. His joyful presence will be always remembered. Have you met him? Tell us anything you can remember about him. #forams #cushmanfoundation #foramsforlife #foramfact https://lnkd.in/d56gkCb8 Brought to you by renata moura

Happy #FossilFriday here is little #ForamFact: Did you know… Amphistegina lobifera are major producers of carbonate sediments in coastal waters across the subtropical/tropical Indo-Pacific region. The A. lobifera found in the Mediterranean likely emerged from individuals that came through the Suez Canal in the past 150 yrs.

Happy #FossilFriday #ForamFriday everybody! Did you know… Foraminifera can be used as a model of the extensive variability in genome dynamics among eukaryotes? Foraminifera present complex life cycles that defy traditional eukaryotic models. They include extensive endoreplication and heterokaryosis, where germline and somatic functions are separated. These insights enhance our understanding of eukaryotic genome dynamics and biodiversity. To learn more: Goetz, E. J., Greco, M., Rappaport, H. B.,Weiner, A. K. M.,Walker, L.
