Abstract. Deep-sea sediments constitute a unique archive of ocean change, fueled by a permanent rain of mineral and organic remains from the surface ocean. Until now, paleo-ecological analyses of this archive have been mostly based on information from taxa leaving fossils. In theory, environmental DNA (eDNA) in the sediment has the potential to provide information on non-fossilized taxa, allowing more comprehensive interpretations of the fossil record. Yet, the process controlling the transport…

Planktonic foraminifera eDNA signature deposited on the seafloor remains preserved after burial in marine sediments

The study shows that the planktonic eDNA preserved in marine sediments has the potential to record climatic and biotic changes in the pelagic community with the same spatial and temporal resolution as microfossils.

Planktonic foraminifera genomic variations reflect paleoceanographic changes in the Arctic: evidence from sedimentary ancient DNA

This study correlated the distribution of ribosomal amplicon sequence variants (ASVs) with paleoceanographic changes by analyzing the high-throughput sequence data assigned to Neogloboquadrina pachyderma in a 140,000-year-old sediment core from the Arctic Ocean.

Patterns of eukaryotic diversity from the surface to the deep-ocean sediment

Remote deep-ocean sediment (DOS) ecosystems are among the least explored biomes on Earth. Genomic assessments of their biodiversity have failed to separate indigenous benthic organisms from sinking

Changes in the composition of marine and sea-ice diatoms derived from sedimentary ancient DNA of the eastern Fram Strait over the past 30 000 years

Abstract. The Fram Strait is an area with a relatively low and irregular distribution of diatom microfossils in surface sediments, and thus microfossil records are underrepresented, rarely exceed the

The potential of sedimentary ancient DNA for reconstructing past sea ice evolution

The results corroborate sea ice reconstructions made by traditional tools, and demonstrate the potential of sedimentary aDNA, focusing primarily on microbial eukaryotes, as a new tool to better understand sea ice evolution in the climate system.

NGS-metabarcoding revealing novel foraminiferal diversity in the Western Pacific Magellan Seamount sediments

Seamount is a unique deep-sea ecosystem widely distributed in the world. Its biodiversity is vibrant due to its specific geographical and hydrological conditions. However, the diversity and features

Eukaryotic Biodiversity and Spatial Patterns in the Clarion-Clipperton Zone and Other Abyssal Regions: Insights From Sediment DNA and RNA Metabarcoding

The abyssal seafloor is a mosaic of highly diverse habitats that represent the least known marine ecosystems on Earth. Some regions enriched in natural resources, such as polymetallic nodules in the

DNA Metabarcoding of Deep-Sea Sediment Communities Using COI: Community Assessment, Spatio-Temporal Patterns and Comparison with 18S rDNA

The results showed that COI can be used to accurately characterize the studied communities and constitute a high-resolution method to detect ecological shifts, and highlight thatCOI reference databases for deep-sea organisms have important gaps, and their completeness is essential in order to successfully apply metabarcoding techniques.



Ancient DNA complements microfossil record in deep-sea subsurface sediments

The potential of aDNA to better document the evolution of past marine ecosystems and opens new horizons for the development of deep-sea palaeogenomics is revealed.

Preservation potential of ancient plankton DNA in Pleistocene marine sediments

The late-Pleistocene sediments mainly contained eukaryotic DNA of marine fungi and from terrestrial plants, which could have been introduced via the river Nile at the time of deposition and preserved in pollen grains and suggests a preferential degradation of marine plankton DNA.

Is Planktonic Diversity Well Recorded in Sedimentary DNA? Toward the Reconstruction of Past Protistan Diversity

The application of sequencing techniques to sedimentary DNA could be used to reconstruct past diversity for numerous planktonic eukaryotic groups, and the diversity of a few groups seemed to be poorly preserved in sediments.

PFR2: a curated database of planktonic foraminifera 18S ribosomal DNA as a resource for studies of plankton ecology, biogeography and evolution

All available published and unpublished genetic data was combined to build PFR2, the Planktonic foraminifera Ribosomal Reference database, which allows for an increase in its taxonomic resolution and assures that integrity is maintained by including a complete contingency tracking of annotations and assuring that the annotations remain internally consistent.

Ultra-deep sequencing of foraminiferal microbarcodes unveils hidden richness of early monothalamous lineages in deep-sea sediments

An ultra-deep sequencing-based metagenetic approach is introduced to examine the richness of benthic foraminifera, a principal component of deep-sea meiofauna, and reflects an unexpected diversity of monothalamous lineages that are as yet unknown using conventional micropaleontological observations.

This work used Roche 454 next-generation pyrosequencing of sedimentary 18S rRNA genes to reconstruct the plankton community structure in the Black Sea over the last ca.

Ancient and modern environmental DNA

EDNA has revealed an ancient forest in Greenland, extended by several thousand years the survival dates for mainland woolly mammoth in Alaska, and pushed back the dates for spruce survival in Scandinavian ice-free refugia during the last glaciation.

Planktonic foraminiferal ontogeny and new perspectives for micropalaeontology

Comparative studies of growth series at species and supraspecific levels allowed the identification of three major species groups, each showing three different developmental stages, which introduces new possibilities for establishing a natural classification of planktonic foraminifers.
