Seven sites of 120 m2 each with four transects were examined, counting the individuals per holothurian group: in total 1711 of which 1199 H. atra and 512 H. pardalis. The Morisita index of aggregation was applied to identify the spatial arrangement of individuals: random, uniform or clumped. Holothuria atra was found all around the atoll and densities varied between 0.03 to 4.78 ind m-2. It showed a clumped distribution on the eastern side of the atoll, and random and uniform patterns on the western side. Its broad distribution was attributed to its being a 'habitat generalist species', its tolerance to high temperatures, and its ability reproduce both sexually and asexually. Holothuria pardalis was found in only one site with 4.27 ind m-2 and a clumped distribution. The correlation of the Morisita index and density values of both species revealed that high densities were associated with a high degree of aggregation. This result led us to hypothesize that the clumped distribution of holothurians might provide protection against predators. Other ecological factors causing aggregations are discussed.","PeriodicalId":50716,"journal":{"name":"Cahiers De Biologie Marine","volume":"65 1","pages":"307-315"},"PeriodicalIF":0.6,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89668838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Les echantillons de plancton ont ete preleves a 28 stations au sud du parallele 18°N, la zone la plus meridionale du Golfe du Mexique, durant les mois de mai et novembre 1995. 187 echantillons ont ete recoltes a cinq intervalles de profondeur de la colonne d'eau (0-6, 6-12, 12-18, 45-55 et 95-105 m) avec un filet ouvrant-fermant de 75 cm de diametre et 505 μm de vide de maille. Quatorze especes de Mollusques heteropodes ont ete identifiees ; les especes dominantes, expliquant 97% de l'abondance totale, etaient Atlanta lesueurii (60%), A. gaudichaudi (15%), Firoloida desmarestia (12%) et A. selvagensis (10%). Dans la colonne d'eau, leurs densites plus elevees ont ete enregistrees dans la couche de 0-18 m. Saisonnierement, seule A. gaudichaudi a enregistre son abondance la plus elevee en novembre. Nous suggerons que les variations saisonnieres de dominance des especes d'heteropodes pourraient etre une strategie ecologique permettant d'eviter la competition pour les ressources alimentaires.

L'exposition a des concentrations de 0,1 μg L-' d'atrazine ou de diuron n'indique aucune reduction significative du rendement photosynthetique. Au-dela de cette concentration, Φ PSII diminue progressivement jusqu'a une inhibition totale du processus photosynthetique pour des valeurs de 100 μg L -1 pour le diuron, et 10 mg L -1 pour l'atrazine.

A synopsis of all available literature since the first local marine study published in 1710 by Antoine Ferchauld de Reaumur indicated that 60 benthic species were reported in the Marennes-Oleron Bay for the first time. The sampling effort, i.e. more than 1 station per km(2) and size of the sieving square mesh (1 mm), can partially explain these results. Most of the new recorded species were crustaceans (28 species) and polychaete annelids (25 species) for only five molluscs. First report of Ocinebrellus inornatus, Mollusca Gastropoda, should be noted for the European Atlantic coasts. Additionally, alteration of subtidal habitats, colonized by Crepidula fornicata Linnaeus (Mollusca, Gastropoda) since the 1970's, may also have facilitated the recruitment and spread of some annelid polychaetes which were not previously reported in the Marennes-Oleron Bay. The total number of macrofauna species in the Pertuis Charentais Sea is 858.","PeriodicalId":50716,"journal":{"name":"Cahiers De Biologie Marine","volume":"24 1","pages":"181-222"},"PeriodicalIF":0.6,"publicationDate":"2000-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76810920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
