Los elementos traza, que incluyen a los metales pesados, llegan a los ecosistemas acuáticos desde fuentes naturales y antrópicas. Los metales pesados se encuentran entre los contaminantes ambientales más importantes debido a su toxicidad, permanencia y tendencia a acumularse en los organismos acuáticos, por lo que su estudio es necesario por el riesgo ambiental que representan. El objetivo de este trabajo es presentar los resultados más relevantes en relación a los niveles de metales pesados existentes en diferentes compartimentos de lagos del noroeste de Patagonia. Los estudios realizados determinaron concentraciones de elementos traza en testigos sedimentarios, sedimentos suspendidos, agua, plancton, macroinvertebrados y músculo e hígado de peces. En...

Version évolutive de l’outil opérationnel de numérisation et d’analyse semi-automatique d’images de phytoplancton, utilisant le matériel FlowCAM et le logiciel ZooPhytoImage. Nouvelles perspectives
Provedor de dados: 5
Autores: Wacquet, Guillaume; Grosjean, Philippe; Colas, Florent; Hamad, Denis; Artigas, Luis Felipe.
The coupled system FlowCAM/ZooPhytoImage has become a real operational tool in 2014. However, to be fully adapted to the observations of phytoplankton performed in the context of the REPHY observation network and in order to better respond to present and future requests concerning the evaluation of quality of coastal and marine waters within the European requirements, such as the WFD and MSFD, new functionalities must be integrated into existing tools. Therefore, different axis of development have been proposed by UMONS and Ifremer to adapt both the digitization device and the Zoo/PhytoImage software to the constraints defined by the REPHY. First, version 5 of Zoo/PhytoImage contains recent innovations such as the development of routines to automatically...

Une procédure systématique pour le sous-échantillonnage des prélèvements de plancton
Provedor de dados: 5
Autores: Koutsikopoulos, Constantin; Petitgas, Pierre.
It is often necessary to sub-sample plankton samples even if the precision of the estimation is thereby decreased. A methodological optimization is looked for. The variance depends on the procedure of construction of the aliquot (strategy) and the number of individuals counted (effort). The sub-sampling effort is allocated in a general context of repartition of the total effort between sampling and sub-sampling. This effort depends on the time consumed by the sub-sampling procedure, the volume of the aliquot and the number of individuals counted. For the same effort, a systematic procedure for the construction of sub-samples is more precise than a random one because it travels through the entire sample and is thus less dependent on the spatial distribution...

Pre- and post-settlement events in benthic community dynamics
Provedor de dados: 5
Autores: Fraschetti, S; Giangrande, A; Terlizzi, A; Boero, F.
In all marine benthic environments, organism replacement depends on recruitment limitation, i.e. the impact of both pre- and post-settlement events on the success of recruitment. The relative contribution of pre- versus post-settlement processes in shaping adult populations has been extensively studied. Most analyses concluded that recruitment limitation is a strong determinant of adults' density. The magnitude of its limitation depends on context, varies with species, and can be strongly modified by all the events preceding and following recruitment itself. A comparison of the outcome of recruitment limitation on hard- and soft-bottom communities has often been neglected. The rules governing these two environments, in both the inter- and the subtidal,...

Etude bibliographique de quelques espèces planctoniques et benthiques littorales de la Manche - Volume 3 - Espèces zoobenthiques
Provedor de dados: 5
Autores: Blanchard, Michel.
This document is the third volume of a bibliographical survey of some of the species studied by IFREMER Brest's Coastal Environment Department (DEL) on a regular basis. The studied animals are a selection of characteristic community species (ex: Lanice or Abra) or populations whose density is so large that they are the ideal material for a regular pluri-annual study (ex: Nucule). For some of them, a regular geographical distribution along the Channel coasts, can be another reason for their selection. On the one hand, for some species, which can be easily reached on the tidal zone, works are numerous and documentation heavy, especially in the ethology field (building of tube of Lanice, displacement of Patelle) On the other hand, documentation, if any, is...

Preliminary results from POLMAR III (April 13-18, 1978) (SUROIT III) ATP, primary production and respiration rates in zooplankton. Complément à la Communication du Groupe Ecophysiologie du Centre Océanologique de Bretagne (SAMAIN et al.)
Provedor de dados: 5
Autores: Hendrikson, P.; Hirche, H.j.; Junghans,, U.
ATP, primary production and respiration rates in seston, respiration rates in zooplankton have been investigated after the spill by "AMOCO CADIZ". Gross primary production seems to be similar to the normal situation. The rate of photosynthesis is lower at the "AMOCO CADIZ" station than at any of the others. Respiration rates are surprisingly high at the surface. ATP concentra­tion exhibit an homogeneous pattern, zooplankton respiration are similar to the data obtained in Peruvian upwelled waters or in zooplankton culture. A more detailed computation of data will be necessary before concluding.

Zonal variability of plankton and particle export flux in the equatorial Pacific upwelling between 165° E and 150° W
Provedor de dados: 5
Autores: Le Borgne, R; Rodier, M; Le Bouteiller, A; Murray, Jw.
Observations made during a "La Nina" situation (April-May 1996) in the equatorial Pacific upwelling, between 165 degrees E and 150 degrees W, show the classic deepening of hydrological isolines from east to west, resulting in zonal gradients for surface temperature and macronutrients. However, contrasting with such a gradient, no clear zonal variation could be seen for integrated planktonic biomasses and carbon fluxes, namely: chlorophyll a, bacterial abundances, particulate organic phosphorus, mesozooplankton ash free dry weight, primary production, and the sinking flux of particulate organic carbon (POC). Moreover, mean values of these parameters along the zonal equatorial transect, are not significantly different from those of a 7-day-long time series...

A new bathyphotometer for bioluminescence measurements on the Armorican continental shelf (northeastern Atlantic)
Provedor de dados: 5
Autores: Geistdoerfer, P; Vincendeau, Ma.
A new bathyphotometer has been developed by the Oceanographic Laboratory of the French Naval Academy which has performed a series of in situ bioluminescence: measurements since 1994. It is used as an additional probe to a Seabird (R) CTD. It measures planktonic bioluminescence. It is associated with a SeaTech (R) fluorometer. The Armorican shelf has particularly been investigated since July 1994. Results obtained in January and April 1995 off Brittany (France), at the entrance to the Bay of Douarnenez and in the northern Bay of Biscay are presented as examples. A method to separate the bioluminescence background from sharp peaks is presented. The strength of bioluminescence signals was related to seasonal planktonic biomass fluctuations, low in winter,...

Présence d'un Protogonyaulax sp. sur le littoral atlantique français pendant l'hiver 1987
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele.
A dinoflagellate belonging to Protogonyaulax genera and forming more than 20 cells chains was observed from November 1987 to February 1988 in Vilaine Bay and in the west ofIle d'Yeu (France). This species was not detected in coastal phytoplankton during preceding surveys. Close to Protogonyaulax affinis it seems to be a winter developing species for this coastal area. Vertical distribution shows in december a migration of the patch towards deeper layers. Increasing occurrences of species belonging to Protogonyaulax (Alexandrium Balech) genera inshore or coastal waters need to pay more attention to the taxonomy of such organisms. Some species are effectively well known as poisons producers.

Autores: Grosjean, Philippe.
Zoo/PhytoImage 4 is an « open source » software based on R and ImageJ. It processes numerical images of plankton particles digitized using a FlowCAM, a flat-bed scanner, microor macrophotos, etc. The general concept consists in the individual outlining of particles on the pictures, followed by their measurements (so-called « attributes ») such the size, the shape, transparency, textures, etc. These attributes are then used by a classification tool to automatically predict the taxonomic group the particles belong to. The classifier is obtained after a learning stage using a machine learning algorithm and a training set of pre-identified particles. The algorithm learns to recognize the taxonomic group from the set of attributes measured on the picture. The...

Provedor de dados: 39
Autores: Gomes,Núbia Abrantes; Eskinazi-Leça,Enide; Silva-Cunha,Maria da Glória Gonçalves da.
Aurícula complexa (Gregory) Cleve (Auriculaceae, Bacülariophyceae) é assinalada pela primeira vez para as águas costeiras de Pernambuco, NE do Brasil. A espécie foi encontrada em amostras de plancton, coletadas durante o período de março/87 a fevereiro/88, em quatro estações, localizadas em um perfil perpendicular à costa. O trabalho fornece descrição, distribuição na área estudada e dados ecológicos da espécie, que esteve presente em nove das 48 amostras coletadas. Quantitativamente foi pouco representativa, com percentuais que não atingiram mais que 0,5% da população fitoplanctônica total.

Autores: De Fabricius,Ana Luján M.; Luque,M. Elisa; Boccolini,Mónica.
El presente trabajo se realizó en el arroyo El Chacay y en el río Las Albahacas desde la primavera de 1999 hasta la primavera de 2000. El objetivo de esta investigación fue comparar la composición y abundancia de la comunidad diatómica en ríos y arroyos serranos de la cuenca del río Piedra Blanca, durante un ciclo anual. En total, 121 taxa (especies, variedades y formas) fueron registrados a partir del análisis taxonómico. El orden Pennales predominó en número de especies y porcentaje de frecuencia relativa. El género con mayor número de especies fue Navicula. El número de especies osciló entre un mínimo de 21 en invierno de 2000 en el río Las Albahacas (aguas arriba del balneario) y un máximo de 49 en verano de 2000 en el arroyo El Chacay y en primavera...
