- PublicationOpen AccessSignificance of rare reproduction occurrences among recent nodosariids and other benthic foraminifera(Murcia: Universidad de Murcia, Servicio de Publicaciones, 2005) Meriç, Engin; Görmüs, Muhittin; Nielsen, Jan Kresten; Avsar, Niyazi; Ünsal, Ismail; Sin departamento asociado; Facultad de BiologíaRare morphologies of nodosariids and other benthic foraminifera reported from various locations and depths in the seas present data valuable in interpreting both past and recent environmental conditions. A few abnormal nodosariids and other benthic foraminifera have been found at the Saros Gulf, near the island of Bozcaada, at the Edremit Gulf (northern Aegean Sea) and Gökova Gulf (southern Aegean Sea) off the coast of W Turkey. The unusual morphology of these foraminifera, “improbable” and rare, is mysterious clues to the natural survival of such organisms. Environmental conditions such as temperature and trace elements may play an important role in stimulating such unusual test occurrences. Warm-water sources in deep-sea environments carry rare trace elements that cause unusual appearances of benthic foraminifera during reproduction. These remarkable and rare specimens found by chance provide data relevant to the reproduction history of nodosariids and other benthic foraminifera.
