A total of 156 benthic foraminiferal species were identified, representing the highest documented taxonomic richness for the region. Species richness per station (56–97; mean 80) is more than double that reported from earlier shallow-water surveys, underscoring the deeper Yemeni shelf as a taxonomic richness hotspot. Crucially, these mid-outer shelf assemblages differ fundamentally from shallow Red Sea communities through: (1) significant agglutinated components (mean ∼10.3%, up to 32.1%) that are absent in nearshore studies; (2) scarce symbiont-bearing taxa (&lt; 10%); and (3) the first regional records of taxa including <i>Reophax</i> spp., and <i>Cibicides wuellerstorfi</i>. Multivariate analyses (Q-mode clustering and NMDS) identified three biofacies: (i) carbonate-rich, well-flushed mid-shelf sites (50–89&nbsp;m) with high species richness and mixed hyaline–porcelaneous assemblages; (ii) sheltered outer-shelf sites (107–176&nbsp;m) within the axial corridor with intermediate species richness and stress signals; and (iii) a deeper site (190&nbsp;m; near Bab al-Mandab) dominated by specialized agglutinated taxa (<i>Reophax</i>,<i> Textularia</i>). A defining feature of the recognized Yemeni assemblages is the persistence of porcelaneous miliolids (~ 39.3%) at distal depths, which is in line with the “isothermal warm-basin” character of the Red Sea. The recognized assemblage patterns are interpreted as controlled mainly by bathymetry and episodic organic/oxygen stress (e.g., influence of Bab al-Mandab inflow). Given the limited sample size, these results provide a preliminary but robust, time-averaged baseline for the understudied southern Yemeni Red Sea and highlight priorities for further sampling and in situ environmental measurements.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Beyond the reef: A baseline characterization of the mid-outer shelf benthic foraminifera from the southern Red Sea (Yemen) and their environmental controls","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-12 01:37:52.170673","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Deep shelf benthic foraminifera · Taxonomic richness hotspot · Multivariate analysis","OtherDescriptors":null,"Notes":null,"AnaPub":2026,"MonPub":null,"DateUpdate":"2026-06-09","DateCreate":"2026-06-09","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s41208-026-01139-8"},"refs":null,"anarec":{"AnaID":440523,"PubliDate":2026,"Pagination":"140","XtraPublOfAnaID":null,"ISBN":null,"Volume":"42","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44043,"SerRR":"Thalassas.
