Planktonic Foraminifera species are sensitive to both abiotic and biotic environmental parameters, and have experienced habitat shifts in response to ocean warming since the post-industrial era. In comparison to the seminal works from the 1950s to the 1970s, we reevaluate the ecological niche of planktonic Foraminifera in the modern ocean. Here, we present the most comprehensive update of their modern global ecological niches, vertical habitat distribution and thermal tolerance using the FORCIS database, which includes all available water-column sourced data over the last century. Our analysis of modern planktonic Foraminifera global distribution patterns, over the 1970-2018 interval, reveals the highest diversity in the tropical and subtropical oceans. Planktonic Foraminifera have consistently maintained a depth preference within the upper 100 m of the ocean, likely due to dependence on light and food availability. Spanning temperatures from-2°C to more than 32°C highlights the remarkable thermal tolerance and/or adaptability of PF to a wide range of temperatures. In addition, species that were once restricted to lower latitudes in the early post-industrial era (pre-1970) have been observed at higher latitudes over the past 50 years. Since the 1970s, small to medium-sized species have increased in abundance across all latitudes, from tropical to polar oceans, a trend particularly evident in the extensive data from the eastern North Atlantic. The analyses of the FORCIS database updates the evolving biogeography of modern PF, and advances our understanding of their ecology, providing revised benchmarks for paleoceanographic interpretations and the ecology of modern planktonic calcifiers.
