Eukaryotic Richness in the Abyss: Insights from Pyrotag Sequencing

The deep-sea floor appears as a global DNA repository, which preserves genetic information about organisms living in the sediment, as well as in the water column above it, which can be used for future monitoring of past and present environmental changes.

Global phylogenetic structure of the hyperdiverse ant genus Pheidole reveals the repeated evolution of macroecological patterns

Analysis of the potential climate drivers of richness revealed that the patterns are statistically very similar across different biogeographic regions, with both regional and local richness associated with the same coefficients of temperature and precipitation.

Short rDNA Barcodes for Species Identification in Foraminifera

Six variable regions of the small subunit (SSU) rDNA of foraminifera, known to have rapidly evolving ribosomal genes, are compared and it is proposed that the expansion segment of Helix 37 appears to be the best candidate for barcoding foraminifiera.

Bipolar gene flow in deep‐sea benthic foraminifera

Molecular evidence for exceptionally wide distribution of benthic foraminifera, which constitute the major part of deep‐sea meiofauna, support the hypothesis of global distribution of small eukaryotes and suggest thatDeep‐sea biodiversity may be more modest at global scales than present estimates suggest.

Global genetic homogeneity in the deep-sea foraminiferan Epistominella exigua (Rotaliida: Pseudoparrellidae)

This result confirms the genetic homogeneity of E. exigua, which contrasts with the prevalence of highly differentiated populations in planktonic and shallow-water benthic foraminiferans, and discusses special features of diversifications mechanisms in the deep sea that may be responsible for the lack of genetic differentiation and global distribution of some meiofauna species.

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.

Bowseria arctowskii gen. et sp. nov., new monothalamous foraminiferan from the Southern Ocean

Molecular phylogenetic analyses, based on partial small subunit rDNA sequences, indicate that the new species belong to a clade of single−chambered foraminifers that branch as a sister group to the multi− chambered textulariids and rotaliids.

Molecular analyses reveal high levels of eukaryotic richness associated with enigmatic deep-sea protists (Komokiacea)

It is suggested strongly that komokiaceans provide a habitat structure for a large spectrum of eukaryotes, significantly contributing to maintaining the biodiversity of micro- and meiofaunal communities in the deep sea.

A new genus of xenophyophores (Foraminifera) from Japan Trench: morphological description, molecular phylogeny and elemental analysis

Based on a comparison of the compositions of the agglutinated test wall, the granellare, the stercomare, and the surrounding sediment, the impact of xenophyophores on their habitat is discussed and mass spectra analyses reveal unusually high concentrations of some elements.

The 'mica sandwich'; a remarkable new genus of Foraminifera (Protista, Rhizaria) from the Nazaré Canyon (Portuguese margin, NE Atlantic)

A new genus and species of monothalamous agglutinated foraminifera that occurs mainly at bathyal water depths in the Nazare Canyon off Por- tugal is described, and analysis of a fragment of the SSUrDNA gene indicates that C. patelliformis belongs in a clade branching with Crithionina delacai, C. granum and an undetermined crithioninid species.
