Nomenclatural checklist for Acromegalomma species (Annelida, Sabellidae), a nomen novum replacement for the junior homonym Megalomma Johansson, 1926

Este artículo contiene 20 páginas.Acromegalomma, nomen novum, is introduced as a replacement name for the polychaete genus Megalomma Johansson, 1926 (Annelida, Sabellidae), preoccupied by Megalomma Westwood, 1842 (Insecta, Coleoptera, Carabidae). The historical background of the homonymy and a full list with 36 new combinations in the new genus are included, while two species are considered as species inquirenda.This work was financially supported by the European Community's Seventh Framework Programme (FP7/2007-2013), through the Assemble Grant Agreement no. 227799-ASSEMBLE to the project “Biodiversity of Annelida Polychaeta in the Ria Formosa coastal lagoon: a baseline study”, awarded to J.G. and developed at the CCMAR, University of Algarve (Faro, Portugal).Peer reviewe

First evidence of cell deformation occurrence during a Dinophysis bloom along the shores of the Gulf of Tunis (SW Mediterranean Sea)

Never before observed or cited in Dinophysis studies, deformations in Dinophysis acuminata and Dinophysis sacculus are reported throughout their cellular division phases (cytokinesis, and sulcal list regeneration) in 5 in situ cell cycle studies in the Punic harbors of Carthage (northern Tunisia). Two types of deformation were observed: invaginations in the ventral and dorsal margin and protuberances at the base of the left sulcal list. No virus or bacteria were detected with Syber green stain. In situ division rates (m) varied among seasons and stations for the same species. D. acuminata exhibited moderate (0.22 day 1) to high (0.68 day 1) m rates which were however very low (0.02–0.17 day 1) for D. sacculus in autumn and moderate (0.21–0.35 day 1) in late spring. In 2009 the seasonal distribution of Dinophysis indicates maximum Dinophysis cf. ovum abundance in March and a high number of D. acuminata in early June, while in 2010 maximum abundance of the same species was found in mid-June. Molecular and genetic studies and staining with specific fluorescent strains should be addressed to hopefully explain these Dinophysis cell deformations during their in situ division.Postprin

Spared unconscious influences of spatial memory in diencephalic amnesia

Spatial memory is crucial to our daily lives and in part strongly depends on automatic, implicit memory processes. This study investigates the neurocognitive basis of conscious and unconscious influences of object–location memory in amnesic patients with Korsakoff’s syndrome (N = 23) and healthy controls (N = 18) using a process-dissociation procedure in a computerized spatial memory task. As expected, the patients performed substantially worse on the conscious memory measures but showed even slightly stronger effects of unconscious influences than the controls. Moreover, a delayed test administered after 1 week revealed a strong decline in conscious influences in the patients, while unconscious influences were not affected. The presented results suggest that conscious and unconscious influences of spatial memory can be clearly dissociated in Korsakoff’s syndrome
