A first attempt to estimate population densities of Holothuria atra and H. pardalis in relation to the spatial arrangement of individuals was made around Clipperton atoll. 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.

The present work updates the number of alien molluscs reported in the eastern Mediterranean since 2012 and brings the total to more than 100 species in the Levantine Turkish Coast. Ervilia scaliola Issel, 1869, widespread in the Red Sea, was collected in August 2013 from Tasucu Harbour, Levantine coast of Turkey. This is the first record of E. scaliola in the Mediterranean Sea. Although shipping appears to be the most probable vector of its introduction, Lessepsian migration cannot be ruled out as a pathway.

Cette etude documente la distribution verticale et horizontale des Mollusques heteropodes dans la zone epipelagique neritique du sud du Golfe du Mexique. 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. Le carinariide Carinaria challengeri est signale pour la premiere fois en Atlantique occidental. Nous donnons egalement une documentation detaillee sur la distribution mondiale des 14 especes d'heteropodes identifiees dans cette etude.

Variation genetique du chinchard (Trachurus trachurus) dans les eaux turques. Les variations geographiques de Trachurus trachurus basees sur le gene mitochondrial 16S rDNA a 8 stations, incluant les Mer Noire, Marmara, Egee et le nord-est de la Mer Mediterranee ont ete recherchees. Les analyses RFLP revelent 14 haplotypes chez les 307 individus des differentes populations. La repartition des groupes haplotypiques suit la plupart du temps l'origine geographique des populations. La diversite haplotypique moyenne au sein des populations est elevee (0,7311) et la diversite nucleotidique faible (0,0071). La faible divergence nucleotidique moyenne entre les echantillons est de 0,00271. La plus forte valeur de divergence nucleotidique a ete detectee entre les echantillons de Mer Noire occidentale et orientale (0,01119) et la plus faible (-0,00018) entre les deux echantillons du nord-est de la Mediterranee. Des populations differant par leurs frequences haplotypiques ont ete detectees par la methode de Monte Carlo. La distribution des haplotypes et l'estimation de la divergence nucleotidique met en evidence une forte differenciation de la population de Mer Noire (BS2).

Les herbicides atrazine et diuron sont retrouves en concentrations non negligeables dans les sediments des vasieres littorales des Pertuis Charentais, sur la cote atlantique. Ils ont donc potentiellement un effet toxique sur le microphytobenthos, le compartiment primaire le plus productif de ces milieux intertidaux, par l'action directe qu'ils ont sur les processus meme de la photosynthese. Cet effet a ete etudie par fluorimetrie PAM sur des communautes naturelles, extraites du sediment et soumises a des concentrations d'herbicides de 0,1 μg, L -1 a 10 mg L -1 . Les variations du rendement effectif Φ PSII du photosysteme II en fonction du temps d'exposition aux concentrations indiquees permettent de quantifier l'effet relatif des herbicides sur l'activite photosynthetique. Cet effet est tres rapide puisqu'il s'exprime en moins de 15 minutes. 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. Le diuron apparait donc comme un inhibiteur plus fort que l'atrazine. Seuls les melanges des plus faibles concentrations d'herbicides montrent un effet synergique.
除草剂阿特拉津和迪隆在大西洋沿岸Charentais Pertuis海岸泥滩的沉积物中发现了相当大的浓度。因此，它们通过直接作用于光合作用过程，对微植物底栖生物(这些潮间带环境中最多产的初级隔间)有潜在的毒性作用。采用PAM荧光法研究了从沉积物中提取的天然群落对除草剂浓度为0.1 μg, L -1 ~ 10 mg L -1的影响。photosysteme II的实际收益率的变动对ΦPSII暴露于浓度随时间变化proft可以量化photosynthetique活动除草剂对地位的相对影响。这种效果非常快，不到15分钟就能表达出来。暴露于浓度为0.1 μg L-'的阿特拉津或迪隆后，光合效率没有显著降低。超越这个浓度,ΦPSII进程的逐渐降低,直到彻底抑制photosynthetique值为100μg L - 1,狄龙、并为莠10 mg·L - 1。因此，迪隆似乎是比阿特拉津更强的抑制剂。只有最低浓度的除草剂混合才会产生协同效应。

The catalogue of soft-bottom macrofauna in the Marennes-Oleron Bay (French Atlantic coast) has been updated from a benthic survey conducted in April-May 1995. 262 stations were selected using a stratified random strategy based on sediment types and bathymetric levels. 231 soft-bottom macrofauna species were identified. 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.
根据1995年4月至5月进行的底栖动物调查，马伦纳-奥勒隆湾(法国大西洋沿岸)的软底大型动物群目录已得到更新。基于沉积物类型和水深水平，采用分层随机策略选择262个站点。发现大型软底动物231种。自1710年Antoine Ferchauld de Reaumur发表第一份本地海洋研究报告以来，所有现有文献的摘要表明，在Marennes-Oleron湾首次报告了60种底栖生物。采样努力，即每公里超过1个站点(2)和筛分方形网(1毫米)的大小可以部分解释这些结果。新记录的种类以甲壳类(28种)和多毛纲环节动物(25种)居多，仅有5种软体动物。在欧洲大西洋沿岸首次报道了软体动物腹足纲(ocinebrelus inornatus)。此外，自20世纪70年代以来，潮下栖息地被Crepidula fornicata Linnaeus(软体动物，腹足动物)占领，这也可能促进了一些以前未在Marennes-Oleron湾报道的环节动物多毛类的补充和传播。该海域大型动物种类总数为858种。
