Diatom Community Composition Shifts Driven by Coherent Cyclonic Mesoscale Eddies in the California Current System
… driven by the relative abundance of a single <em>Rhizosolenia</em> species. <em>Rhizosolenia</em> accounted for over 50% of the diatom community in 5 out of 8 offshore eddy stations, with one of these stations characterized by nearly 75% <em>Rhizosolenia</em>. Our results suggest that the …

Structural Characterisation and the Diagenetic Pathways of C25 Highly Branched Isoprenoid Hydrocarbons
… algae, the diatoms Haslea ostrearia and Rhizosolenia setigera are able to biosynthesise C25 HBI alkenes. Large scale cultures of H. ostrearia studied previously, allowed isolation and characterisation of five HBI polyenes. The stereochemistry of the chiral centres was not reported …

Physical constraints on phytoplankton in estuaries and shallow coastal waters
… from the spring to the summer months. Diatoms (Rhizosolenia delicatula) proliferated in the spring, where the population was localised in the near-bottom layers, whilst the summer bloom was dominated by autotrophic dinoflagellates (Prorocentrum micans and Peridifiium trochoideum), manifesting in …

SOURCES AND STRUCTURES OF COMMONLY OCCURRING HIGHLY BRANCHED ISOPRENOID ALKENES
… algae Haslea ostrearia (C25 alkenes) and Rhizosolenia setigera (C25 or C30 alkenes) were the only reported biological sources of these compounds. However, there remained a poor correlation between isomers found in diatoms and those commonly reported in sediments and water column particles. …

Variabilidad espacio-temporal en la estructura de las comunidades planctónicas en el estrecho de Gibraltar
… por diatomeas de gran tamaño (géneros Guinardia, Rhizosolenia, Chaetoceros, Proboscia, Leptodylindrus y Lauderia, así como diatomeas centrales formando cadenas) que suponen el 79% de la abundancia relativa. La zona oeste, y el canal en cambio están dominados por fitoplancton pequeño …

High resolution palaeoceanography and palaeoclimatology from mid and high latitude Late Cretaceous laminated sediments
… blooms flux, respectively. Near-monospecific Rhizosolenia laminae frequently occur above vegetative laminae, relating to subsequent ‘fall dump’ flux. Common silicoflagellate/setae-rich laminae, often containing diatom hash, occur beneath resting spore laminae, interpreted as the early spring …
