Uncovering the complexities of trophic and metabolic interactions among microorganisms is essential for the understanding of marine biogeochemical cycling and modelling climate-driven ecosystem shifts. High-throughput DNA sequencing methods provide valuable tools for examining these complex interactions, although this remains challenging, as many microorganisms are difficult to isolate, identif...

Using shells collected from a sediment trap series in the Madeira Basin, we investigate the effects of seasonal variation of temperature, productivity, and optimum growth conditions on calcification in three species of planktonic Foraminifera. The series covers an entire seasonal cycle and reflects conditions at the edge of the distribution of the studied species, manifesting more suitable grow...

Many species of Indo-Pacific holobenthic foraminifera have been introduced and successfully established sustainable populations in the Mediterranean Sea over the past few decades. However, known natural and anthropogenic vectors do not explain how these species were introduced long distances from their origin. We present evidence for a novel marine bioinvasion vector explaining this long-distan...

Abstract. The Rashrashiyah Formation of the Sirhan Basin in northern Saudi Arabia contains diverse assemblages planktonic foraminifera. We examined biostratigraphy, stratigraphic range and preservation upper Eocene Assemblages are well-preserved diverse, with 40 species 11 genera. All samples assigned to Priabonian Globigerinatheka semiinvoluta Highest Occurrence Zone (E14), consistent calcareo...

Abstract The trophic strategies of cold-water planktonic foraminifera are not well understood due to the challenge culturing them in polar conditions. Here, we identify previously unknown ectoplasmic and cytoplasmic projections three species thriving subpolar marine environments: Globigerina bulloides, Neogloboquadrina incompta pachyderma. These structures were observed during routine monitorin...

This study is focused on the biostratigraphy, sedimentary environments, facies distribution, and sequence stratigraphy of the Coniacian–Santonian sediments of Tange-Bulfaris section. Five assemblage zones have been recognized by distribution of the foraminifera in the study area. Assemblage zone 1(Chara Ostracods zone) is Coniacian in age and occurs in the lower part of the succession. Assembl...
