Spatial patterns of intertidal peracarids, associated with the alga Corallina elongata, were studied along the whole Iberian Peninsula. A total of 28,215 specimens were collected, comprising 78 different species (57 amphipods, 16 isopods, 4 tanaids and 1 cumacean), most of them with Atlantic-Mediterranean distribution (60%) and only 9% of Mediterranean endemics. Gammarids were dominant in abundance and number of species, representing more than 70% of the total peracarids. The most common species collected during the present study were the caprellid Caprella penantis, the gammarids Hyale schmidti, Hyale stebbingi, Jassa cf. falcata and Stenothoe monoculoides, the isopod Ischyromene lacazei and the tanaid Tanais dulongii. Caprellids and tanaidaceans presented their highest populations in the stations of the Strait of Gibraltar, whereas isopods were more abundant in Atlantic stations. Univariate analyses did not reflected differences in number of species, abundance and ShannonWeaver diversity between Mediterranean and Atlantic. However, cluster analyses and Whittaker index, as measure of ß-diversity, showed a different species composition between Mediterranean and Atlantic and a replacement of species along the coast, especially at the Strait of Gibraltar. The turnover mainly affected species of the same genera, probably related with sympatric speciation. CCA and BIO-ENV analyses showed high correlations between environmental measures (especially conductivity) and peracarid distribution. Mediterranean species tolerated higher values of conductivity and temperature, while Atlantic species were associated with stations characterized by higher oxygen concentrations.

“…Evidence has been provided by studies in sites with different species of seagrass, macroalgae or saltmarsh (Lewis & Stoner, 1983;Lewis, 1984;Virnstein & Howard, 1987;Lana & Guiss, 1991;Schneider & Mann, 1991;Attolini et al, 1997;Flynn et al, 1996Flynn et al, , 1998Dubiaski-Silva & Masunari, 1995, 1998Chananich & Wilson, 2000).…”

The monthly fluctuations of amphipods associated to the algae Bryocladia trysigera was described from March 1997 to February 1998 at the rocky shore known as Poço de Anchieta in the Peruíbe Beach, Itanhaém, Southeastern Brazil. A total of 75,344 individuals were sampled, belonging to 10 species and 9 families. Three species dominated the phytal in number: Hyale nigra, Caprella danileviskii and Caprella penantis. Despite the alternation in dominance of the 3 most abundant species, the amphipod species composition remained generally unchanged, so that the majority of the species were observed in all sampling months. The temporally changing pattern of the community structure, with a decline in amphipod abundance in winter followed by an increase in spring, was probably due to a higher predation pressure in winter period.

“…Igualmente, se destaca la presencia de anfípodos, como productores secundarios y terciarios, asociados a otros invertebrados marinos y algas (Tararam, Wakabara, & Leite, 1986), dependiendo de la interacción con sus depredadores, exposición al oleaje y complejidad del hábitat (Chavanich & Wilson, 2000). Poco abundantes, pero no menos importantes, fueron los equinodermos, sipuncúlidos y nemertinos presentes en esta zona; resultados similares fueron señalados por CAMUDOCA (2006) en el litoral rocoso de la costa norte del estado Sucre.…”

Diversity, abundance and distribution of benthic macrofauna on rocky shores from North Sucre State, Venezuela. The rocky intertidal zone is among the most extreme physical environments on Earth. Organisms living in this area are constantly stricken by physico-chemical and biological factors. Due to the ecological importance of these areas, we studied the diversity, abundance and distribution of the rocky coastline benthic macrofauna, from the North coast of Sucre State, Venezuela. We performed bimonthly samplings from November 2008 to September 2009. The collection of biological material in the littoral zone (supra, mid and infralittoral) was done manually with a grid of 0.25m 2 . Organisms were preserved in 10% formalin for later identification and analysis (ecological parameters and Kruskal-Wallis test to the abundance and diversity). We found a total 19 020 organisms (86spp.), in 8 phyla, 45 families and 47 genera. Mollusks were the most abundant and diverse (58 spp.), followed by arthropods (12spp.), annelids (7spp.), echinoderms (5spp.), and the less represented cnidarians, sipunculids, nemertinids and urochordates (1sp.). The zonation found coincided with the universal scheme of zonation. The towns of Rio Boca and Rio Caribe presented the highest values of ecological parameters, and the lowest were found in Playa Grande. Statistical significant differences were found in the abundance and diversity of macrofauna among the three zones. The little information on the composition and distribution of macrobenthic rocky coastline, prevents a better comparison, however the results contribute to the knowledge of the marine biodiversity in this region.

Epub 2014 September 01.Key words: benthic, rocky, coast line, ecology, diversity.El litoral rocoso está constituido en su mayor parte por rocas sometidas a la acción de las olas y mareas. Representa uno de los ambientes físicamente más extremos de la tierra.En las costas litorales rocosas, los diferentes organismos (invertebrados y vertebrados) que allí habitan, se han adaptado a estos ambientes, determinando una zonación o distribución de especies, en franjas o bandadas, según ciertos factores incidentes: físico-quí-micos (como el régimen climático, energía del viento, oleaje, intensidad lumínica, mareas, topografía del sustrato, salinidad y temperatura) y biológicos (presión por depredadores, competencia por espacio y alimento) (Dauer, 1993;Saiz, 1997). Consecuentemente, estos factores y la comunidad espacial condensada, han hecho de la zona intermareal un "laboratorio natural ideal" para estudiar el papel que tienen los organismos en la determinación de la abundancia y distribución en la naturaleza (Lewis, 1961;Paine, 1974).En este sentido, los patrones de distribución de la macrofauna bentónica costera ha servido como herramienta básica para la identificación y delimitación de áreas biogeográfi-cas definidas, por lo que, la evaluación de las comunidades marinas, se basa principalmente en estudios ecológicos que permiten ...
