Grazing by the Sea Urchins Arbacia Lixula L. and Paracentrotus Lividus Lam. in the Northwest Mediterranean
Journal of Experimental Marine Biology and Ecology, L 241 (1999) 81±95 Grazing by the sea urchins Arbacia lixula L. and Paracentrotus lividus Lam. in the Northwest Mediterranean Fabio Bulleri, Lisandro Benedetti-Cecchi* , Francesco Cinelli Dipartimento di Scienze dell'Uomo e dell'Ambiente via A. Volta 6, 56126 Pisa, Italy Received 2 October 1998; received in revised form 12 April 1999; accepted 5 May 1999 Abstract The sea urchins Arbacia lixula and Paracentrotus lividus are common on shallow subtidal reefs in the Mediterranean. Previous studies on the ecology of these species reported that P. lividus is generally more abundant on horizontal or gently sloping substrata, where it forages mainly on erect algae. In contrast, A. lixula is more common on vertical substrata and it is considered a main grazer of encrusting coralline algae. Observations on some rocky shores in the Ligurian sea indicated that P. lividus occurs mainly in crevices at the bottom of the vertical walls, and that neither species is present on horizontal or sub-horizontal substrata. In this study we investigated the distribution and abundance of the two species of sea urchins on vertical substrata at different spatial scales and through time. A ®eld experiment was used to test whether A. lixula constrained the distribution of P. lividus on vertical substrata, and to test for the predicted differences in the effects of the 2 species on assemblages of algae and invertebrates. Four treatments were used: (1) control (sea urchins left untouched); (2) A. lixula removed, P. lividus present; (3) A. lixula present, P. lividus removed, and (4) both species removed. -

However, the effects on invertebrate species are HSP70 not yet fully understood. The aim of this study was to determine the biochemical responses of Arbacia lixula Marine invertebrates exposed to high-frequency noise. Protein concentration, enzyme activity (esterase, phosphatase and peroxidase) Noise and cytotoxicity in coelomic fluid were compared in individuals exposed for three hours to consecutive linear Acoustic stimulus sweeps of 100 to 200 kHz lasting 1 s, and control specimens. Sound pressure levels ranged between 145 and Physiological stress 160 dB re 1μPa. -
Echinodermata) Durant El Període 2014-2018
NEMUS núm. 9. 2019 Sobre la descripció d’espècies noves de la classe Echinoidea (Echinodermata) durant el període 2014-2018 Vicent Gual i Orti1, Javier Segura Navarro1 & Enric Forner i Valls1 1. Ateneu de Natura. Sant Roc, 125, 3r. 5a. 12004 Castelló de la Plana. [email protected]. En el camp de la paleontologia el treball de descripció de les espècies que s’han conservat al registre fòssil està molt lluny d’haver conclòs. De manera que d’una manera dispersa i arreu del món hi ha un continu degoteig de publicacions on es descriuen espècies noves. Dins la paleontologia, l’equinologia, ocupa un paper significatiu tant a nivell científic com a nivell de col·leccionisme privat i museístic. Aquesta importància, potser està moti- vada per la bona conservació de la carcassa dels equínids, que està constituïda per calcita, cosa que afavoreix la seua fossilització i proporciona un registre fòssil ric de la classe Echinoidea. L’interès del treball és donar un visió global i actual dels treballs de descripció de la classe Echinoidea, de la qual no s’ha publicat cap treball de recopilació des de l’any 2008. Disposar d’una fotografia, una mostra, del que està passant ara. Per altra banda, es vol aprofundir en certs aspectes que sovint no són analitzats. Com el lloc geogràfic i les edats geològiques en les quals s’estan fent descripcions o en quines revistes científiques i per qui s’estan publicant les espècies noves. De l’estudi es conclou, atesos els treballs que s’ha pogut enregistrar, que durant els últims cinc anys, 2014-2018, s’han descrit al món 74 espècies noves d’equínids, per 77 autors, que s’han publicat en 30 revistes diferents, mitjançant 53 articles. -

Abundance of the sea urchin Paracentrotus lividus (Lamarck) was monitored at 7 sites (4 inside and 3 outside the reserve), and 2 distinct habitats (fields of big boul- ders and vertical walls). P. lividus exhibited sign~ficantvariability in density over time on boulders, both inslde and outside the reserve, whereas its density dld not vary significantly on vertical walls. P hvjdus populations differed significantly in size-structure across sites, varying from unimodal to blmodal among sltes and years. Density and mean size of P. lividus were not significantly different between the protected and the unprotected area in either of the 2 habitats. -

Our results 25 show that the gonadosomatic index of A. lixula follows a seasonal cycle which peaks in May-July 26 and attains its lowest values in October-November every year. The time course of the 27 gonadosomatic index matched closely the photoperiod cycle. We also found a remarkable inter- 28 annual variability in the maximum value of gonadosomatic index, which correlated with mean 29 water temperature during the gonad growth period (winter and spring). Gonad histology was also in 30 agreement with a single gametogenic cycle per year in this species. We explored the application of 31 circular statistics to present and analyse gonadal development data, which allowed us to adequately 32 handle the high intra-individual variability detected, with several developmental stages commonly 33 found within the same gonad. -

These authors contributed equally to this work. y Received: 19 June 2020; Accepted: 2 August 2020; Published: 4 August 2020 Simple Summary: Arbacia lixula, Paracentrotus lividus and Sphaerechinus granularis play a key role in many sublittoral biocommunities of the Mediterranean Sea. However, their skeletons seem to differ, both morphologically and in chemical composition. Thus, the skeletal elements display different properties, which are affected not only by the environment, but also by the vital effect of each species. We studied the microstructural morphology and crystalline phase of the test and spines, while also examining the effect of time on their elemental composition. Results showed morphologic differences among the three species both in spines and tests. They also seem to respond differently to possible time-related changes. The mineralogical composition of P.lividus appears to be quite different compare to the other two species. The results of the present study may contribute to a better understanding of the skeletal properties of these species, this being especially useful in predicting the effects of ocean acidification. -
