Fragment or broken? Improving the planktonic foraminifera fragmentation assessment

Planktonic foraminifera tests can suffer dissolution, which usually involves partial damage, weight loss, and fragmentation. Since planktonic foraminifera of planktonic foraminifera tests, but cal...

Albian Foraminifera in the uppermost part of Lhoty Formation at the Bystrý Creek Section (Cretaceous of Silesian Unit, Outer Western Carpathians)

Reach association of planktonic foraminifera were identified in the thin-sections of the uppermost part of Lhoty Formation in the Silesian Unit. They identify the Biticinella breggiensis Zone and Thalmanninella subticinensis Subzone...

Convergent evolution of spherical shells in Miocene planktonic foraminifera documents the parallel emergence of a complex character in response to environmental forcing

The spherical encompassing final chamber of the planktonic foraminifera Orbulina universa is a prime example of a complex character whose evolution has been documented by a sequence of intermediate forms. However, the mechanism that...

Reproduction dynamics of planktonic microbial eukaryotes in the open ocean

Understanding the biology of reproduction of an organismal lineage is important for retracing key evolutionary processes, yet gaining detailed insights often poses major challenges. Planktonic Foraminifera are globally distributed m...

Where it's worth it: frequency and spatial distribution of bioerosional drill holes in planktonic foraminifera reveal different strategies in site selectivity

Despite advances in understanding planktonic foraminifera environmental interactions, their role as prey remains elusive, often inferred from indirect evidence, although knowledge for planktonic foraminifera remain...

Stable Oxygen Isotope Composition Is Biased by Shell Calcification Intensity in Planktonic Foraminifera

Planktonic Foraminifera are widely used for environmental reconstructions through measurements of their shell's geochemical characteristics, including its stable oxygen and carbon isotope composition. Using these parameters as ...
