Adaptation and acclimatization to ocean acidification in marine ectotherms: an in situ transplant experiment with polychaetes at a shallow CO₂ vent system
Metabolic rate determines the physiological and life-history performances of ectotherms. Thus, the extent to which such rates are sensitive and plastic to environmental perturbation is central to an organism's ability to function in a changing environment. Little is known of long-term metabolic plasticity and potential for metabolic adaptation in marine ectotherms exposed to elevated pCO₂. Consequently, we carried out a series of in situ transplant experiments using a number of tolerant and sensitive polychaete species living around a natural CO₂ vent system. Here, we show that a marine metazoan (i.e. Platynereis dumerilii) was able to adapt to chronic and elevated levels of pCO₂. The vent population of P. dumerilii was physiologically and genetically different from nearby populations that experience low pCO₂, as well as smaller in body size. By contrast, different populations of Amphiglena mediterranea showed marked physiological plasticity indicating that adaptation or acclimatization are both viable strategies for the successful colonization of elevated pCO₂ environments. In addition, sensitive species showed either a reduced or increased metabolism when exposed acutely to elevated pCO₂. Our findings may help explain, from a metabolic perspective, the occurrence of past mass extinction, as well as shed light on alternative pathways of resilience in species facing ongoing ocean acidification

Sabellidae is the second most diverse polychaete family in the Adriatic Sea, after Syllidae. Herein we report the updated list of
the Sabellidae and Fabriciidae families in the Adriatic Sea deriving both from literature data and presently conducted
researches in the northern Adriatic. During these researches polychaetes were sampled from three offshore soft-bottom and
three coastal rocky shore stations. Among the analysed material three Sabellidae species are new records for the Adriatic
fauna, while four Sabellidae and one Fabriciidae species were recorded for the first time in the northern part. Two new
species were found and described: Amphicorina rovignensis spec. nov. and Megalomma pseudogesae spec. nov. These findings
increase the number of Sabellidae taxa recorded in the northern Adriatic from 29 to 38. Our results point out the lack of
the recent taxonomic studies in the area, but might also indicate the widening of the species areal. Taking into consideration
that studies on only six stations raised the number of known sabellid taxa from the area by 31%, our results support the need
for the regular taxonomic updating of the polychaete fauna in the northern Adriatic
The genus Echinofabricia (Annelida: Fabriciidae) in the Mediterranean Sea with the description of E. rousei sp. nov.
The new species Echinofabricia rousei is described for the Mediterranean Sea based on specimens collected along the Sardinia
Coast (Porto Conte). The genus Echinofabricia is reported for the first time in the Mediterranean area. At present three species
are described within the genus: E. goodhartzorum, described from the Caribbean, E. dubia, described from the East Pacific
(Hawaii) and E. alata from Australia
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 genus Novafabricia Fitzhugh, 1990 (Polychaeta: Sabellidae: Fabriciinae) en la costa italiana (Mar Mediterráneo) con la descripción de N. posidoniae n. sp.
The new species, Novafabricia posidoniae is described for the Mediterranean Sea, and Novafabricia sp. cf. N. infratorquata (Fitzhugh, 1983) is reported for the eastern Mediterranean basin. The genus Novafabricia Fitzhugh, 1990, represented up to now in the Mediterranean only by N. infratorquata, is recorded for the first time along the Italian coast. Novafabricia posidoniae belongs to the group of Novafabricia species with pseudospatulate chaetae present in thoracic chaetigers 3-5. The addition of this new species raises the number of Novafabricia species to 10. El genero Novafabricia Fitzhugh, 1990, representado en el Mediterráneo únicamente por N. infratorquata, se cita por primera vez para las costas italianas. Se describe Novafabricia posidoniae como especie nueva en base a ejemplares del Mediterráneo y se cita Novafabricia sp. cf. N. infratorquata (Fitzhugh, 1983) para el Mediterráneo oriental. N. posidoniae pertenece al grupo de especies del género con sedas pseudoespatuladas en los setígeros 3-5. La presente descripción incrementa a 10 el número de especies conocidas de Novafabricia.

Este artículo contiene 16 páginas, 5 figuras.The polychaete Notaulax yamasui sp. n. (Sabellidae) is described from Okinawa and Ogasawara, south
Japan, where it was found living embedded in a dead skeleton of the coral Porites sp. The new species is
characterized by the presence of a pigmented sub-distal swelling on the tips of the crown radioles, a unique
feature among species of the genus. Besides, its collar chaetae have an L-shape orientation, and the dorsal
basal flanges of the branchial lobes are long and have a dorsal joint.Peer reviewe
El desarrollo larvario de Sabellastarte spectabilis (Grube, 1878) (Polychaeta: Sabellidae) en Hawaii
The sabellid polychaete Sabellastarte spectabilis is common in bays and harbours throughout Hawaii. It has become one of the most harvested marine ornamental species in the State. Collection can be difficult and potentially damaging to the reef community. Understanding the reproduction and life history of this polychaete will benefit the marine ornamental trade by facilitating aquaculture of the species and coral reef conservation by decreasing destructive collecting practices. There is very little known about the biology of this species. Experiments were conducted at the Hawaii Institute of Marine Biology to induce and document spawning and larval development. Oocytes range between 150-200 µm in diameter and sperm have spherical heads. Cell division in fertilized eggs begins approximately twenty minutes after spawning. Developmental stages were documented using light and scanning electron microscopy. Swimming larvae are first seen 7-8 h after spawning. Larvae have a well-developed prototroch and a less conspicuous neurotroch and metatroch. Two chaetigers develop sequentially on days 4 and 5 and settlement occurs 6-7 days after spawning. Metamorphosis occurs gradually from days 6-8. This is the first reported induction of spawning and description of larval development from fertilized egg to settlement and metamorphosis for this species.El poliqueto sabélido Sabellastarte spectabilis es común en bahías y puertos de Hawaii. Este sabélido ha llegado a ser una de las especies ornamentales marinas más recolectadas en el estado, pero su recolección es difícil y en muchos casos ocasiona daño a la comunidad arrecifal. Pese a ello, el conocimiento sobre su biología es escaso. El estudio de la reproducción y ciclo de vida de estos sabélidos facilitará su cultivo y beneficiará al mercado de especies ornamentales, a la vez que la diminución de la recogida destructiva se espera pueda contribuir a la conservación de los arrecifes coralinos. En el Hawaii Institute of Marine Biology se realizaron algunos experimentos con la finalidad de inducir y documentar su reproducción y desarrollo larvario. Los huevos miden entre 150-200 μm de diámetro y los espermatozoos presentan cabezas redondas. La división celular de huevos fertilizados comienza aproximadamente 20 minutos después del desove. Los estadios larvarios se documentaron con microscopios de luz y microscopia electrónico de barrido. Las primeras larvas aparecen 7-8 horas después del desove. Las larvas tienen una prototroca muy bien desarrollada y una neurotroca y metatroca menos conspicua. Entre los días 4 y 5 se desarrollan dos setígeros y el reclutamiento ocurrió 6-7 días después del desove. La metamorfosis ocurre gradualmente entre los días 6-8. Este estudio describe por primera vez la inducción del desove y la descripción del desarrollo larvario desde la fertilización del huevo hasta el establecimiento y metamorfosis de la especie.
