Checklist of tidepool fishes from Jericoacoara National Park, southwestern Atlantic, with additional ecological information Biota Neotropica
Machado,Fabiola S.; Macieira,Raphael M.; Zuluaga Gómez,Mario A.; Costa,Alexandra F.; Mesquita,Esther M.C.; Giarrizzo,Tommaso.
Ichthyofauna from 29 tidepools in Jericoacoara National Park (Ceará State, Brazil) was sampled. A total of 733 fishes, comprising 16 species belonging to 12 families, was collected. The three most abundant species were the frillfin goby Bathygobius soporator, the sergeant-majorAbudefduf saxatilis and the molly miller Scartella cristata. An invasive species from the Indo-Pacific, the Muzzled blenny Omobranchus punctatus, was also recorded. The known geographic distribution of the blenny Hypleurochilus fissicornis was extended approximately 2,500 km northward. These findings highlight the lack of knowledge of the rocky intertidal ecosystems along the Brazilian coast, an area that needs more sampling effort and ecological data.

Ecomorphological patterns of the fishes inhabiting the tide pools of the Amazonian Coastal Zone, Brazil Neotropical Ichthyology
Soares,Bruno Eleres; Ruffeil,Tiago Octavio Begot; Montag,Luciano Fogaça de Assis.
The present study was based on the identification of the ecomorphological patterns that characterize the fish species found in tide pools in the Amazonian Coastal Zone (ACZ) in the Pará State, Brazil. Representatives of 19 species were collected during two field campaigns in 2011. The dominance, residence status, and trophic guild of each species were established, and morphometric data were obtained for up to 10 specimens of each species. A total of 23 ecomorphological attributes related to locomotion, position in the water column, and foraging behavior were calculated for the analysis of ecomorphological distance. Principal Component Analysis (PCA) was utilized for the evaluation of ecomorphological attributes that explained the variation among species....

Effects of seasonal dynamics in a Zostera noltii meadow on phosphorus and iron cycles in a tidal mudflat (Arcachon Bay, France) ArchiMer
Deborde, Jonathan; Abrill, Gwenael; Mouret, Aurelia; Jezequel, Didier; Thouzeau, Gerard; Clavier, Jacques; Bachelet, Guy; Anschutz, Pierre.
A study was conducted in Arcachon Bay, France, to determine the effect of seasonal dynamics in a Zostera noltii meadow on P and Fe cycles in the superficial sediments of a tidal mudflat. The redox-sensitive Fe particulate pool and associated P in the root zone showed a seasonal variation following the growth and decay of Z. noltii biomass, with a maximum content during the growth period. In comparison, the bare sediments did not show significant seasonal changes. A dissolved inorganic phosphorus (DIP) uptake was measured from the water column to the sediment in vegetated sediments, whereas a net DIP efflux was observed in the unvegetated sediments. During the growth period, the formation of an iron oxihydroxide-rich zone occurred and acted as a trap for...

Hydroids (Cnidaria, Hydrozoa) of the intertidal zone of Governador and Paquetá islands, Guanabara Bay, Rio de Janeiro, Brazil Iheringia, Sér. Zool.
Grohmann,Priscila A..
During six consecutive months, sampling were made at three points located on Governador Island and three on Paquetá Island in Guanabara Bay, Rio de Janeiro, Brazil. Material was collected from dock pilings and rocks in the intertidal zone. In these samples, five species belonging to three families, Corynidae, Kirchenpaueriidae and Campanulariidae, were identified. The campanulariid species Obelia dichotoma Linnaeus, 1758, dominated at nearly all points sampled. The small number of species obtained in this survey is attributed to the intense pollution in the bay, which borders the second-largest industrial complex and the second-largest demographic center of Brazil.

Macrophytobenthos des platiers rocheux intertidaux et semi-exposés da la région de Safi-Essaouira (Maroc occidental) ArchiMer
Birje, J; Verlaque, M; Poydenot, F.
In 1990, a study of the phytobenthos of the rocky intertidal platforms in the Safi-Essaouira region (Sidi Boulbra, Western Morocco) was carried out at three sites. The intertidal zonation was analysed along permanent transects, and a qualitative and quantitative study of two characteristic units of the eulittoral vegetation - the vegetation belt of Fucus spiralis and the communities of Florideophyceae - was made. One hundred and twenty-nine macroalgal taxa and three phases were listed: 19 Ulvophyceae, 19 Fucophyceae, 1 Bangiophyceae and 93 Florideophyceae. The intertidal communities of the area are typical of semi-exposed and unpolluted platforms of Western Morocco, in the eulittoral zone, most of the typical Fucales that occur along the NE Atlantic coasts...

Population biology and secondary production of the stout razor clam Tagelus plebeius (Bivalvia, Solecurtidae) on a sandflat in southeastern Brazil Rev. Bras. Zool.
Abrahão,Jolnnye R.; Cardoso,Ricardo S.; Yokoyama,Leonardo Q.; Amaral,A. Cecilia Z..
The population biology and production of the stout razor clam Tagelus plebeius Lightfoot, 1786 were investigated on an intertidal sandflat on the southeast coast of Brazil (Enseada Beach, São Sebastião, state of São Paulo) between April 1997 and April 1998. Two rectangular sites of 50 X 10 m parallel to the waterline were established, site A (upper intertidal level) and site B (middle intertidal level), where the samples were taken in an 0.5 x 0.5 m quadrat. High abundances were recorded in winter and spring, with no significant differences between the sites. The high bivalve abundances were related to the presence of very fine homogeneous sediment with low salinities. Tagelus plebeius had negative allometric growth, characteristic of deep burrowers for...

Population dynamics of the pea crab Austinixa aidae (Brachyura, Pinnotheridae): a symbiotic of the ghost shrimp Callichirus major (Thalassinidea, Callianassidae) from the southwestern Atlantic Iheringia, Sér. Zool.
Peiró,Douglas F; Mantelatto,Fernando L.
The Pinnotheridae family is one of the most diverse and complex groups of brachyuran crabs, many of them symbionts of a wide variety of invertebrates. The present study describes the population dynamics of the pea crab Austinixa aidae (Righi, 1967), a symbiont associated with the burrows of the ghost shrimp Callichirus major (Say, 1818). Individuals (n = 588) were collected bimonthly from May, 2005 to September, 2006 along a sandy beach in the southwestern Atlantic, state of São Paulo, Brazil. Our data indicated that the population demography of A. aidae was characterized by a bimodal size-frequency distribution (between 2.0 and 4.0 mm and between 8.0 and 9.0 mm CW) that remained similar throughout the study period. Sex ratio does not differ significantly...

Prévention des mortalités estivales de naissain d'huîtres creuses. Expérimentations sur estran (Rivière d'Auray, été 1998). 1 : comparaison de différents lots de naissain. 2 : tentative "d'endurcissement» du naissain". ArchiMer
Mazurie, Joseph; Kuntz, Gregoire; Claude, Serge; Hirata, Toshio.
Cupped oysters, Crassostrea gigas, often suffer abnormal mortalities during summer, at one year of age. Both scientists and professionnals are interested in finding practical methods to reduce these mortalities. The present study tries to answer two questions : 1- are there any differences of summer mortalities among various batches of spat available from spat collection areas (Arcachon and Charentes) ? 2- is it possible to improve summer survivals by wintering the spat at high air exposure locations (« hardening » procedure) ? The first comparison did not reveal any significant difference between the 16 batches of spat tested (mortalities between 5 % and 30 %). The second comparison in the same summer conditions was not able to show to any improvement...

Spatial distribution of mollusks in the intertidal zone of sheltered beaches in southeastern of Brazil Zoologia
Arruda,Eliane P. de; Amaral,A. Cecilia Z..
The spatial distribution of mollusks in the intertidal zone was examined monthly from August 1995 through July 1997, in Enseada, Barra Velha and Araçá beaches in southeastern of Brazil. One study sector was selected in Enseada and Barra Velha, and two sectors in Araçá (Araçá I and Araçá II). The sectors were 10 m wide and equivalent in length to the width of the intertidal zone. Each sector was divided into three horizontal levels: lower, middle and upper, where the samples were taken with a cylinder corer with a base area of 0.16 m². In order to characterize the intertidal environment in these areas, some environmental variables were analyzed. In general, the mollusks were distributed in the sectors as follows: Enseada - Olivella minuta (Link, 1807) in...

Structure and composition of fish assemblages from São Sebastião Channel tide pools, southwestern Atlantic Biota Neotropica
Pastro,Gabriela; Dias,Gustavo Muniz; Gibran,Fernando Zaniolo.
Abstract Organisms living in tide pools in the intertidal zone are exposed to daily and abrupt changes in temperature, dissolved oxygen, pH and salinity, during tidal cycles. Fish assemblages in tide pools are usually very different from those in surrounding areas; resident species exhibit morphological and ecological adaptations to deal with such a variable environment. In this study, we described the environmental conditions and the fish diversity and composition from four tide pools at the continental margin of the São Sebastião Channel, São Sebastião (23º41'-23º54'S; 45º19'-45º30'W), in southeastern Brazil. Monthly, from January to December 2011, we sampled four tide pools (12 samples per pool), applying a standard protocol to record environmental...
