Absolute abundances of dinoflagellate cysts in surface sediment samples from four sites: Lycopodium marker-grain method

Absolute abundances (concentrations) of dinoflagellate cysts are often determined through the addition of Lycopodium clavatum marker-grains as a spike to a sample before palynological processing. An inter-laboratory calibration exercise was set up in order to test the comparability of results obtained in different laboratories, each using its own preparation method. Each of the 23 laboratories received the same amount of homogenized splits of four Quaternary sediment samples. The samples originate from different localities and consisted of a variety of lithologies. Dinoflagellate cysts were extracted and counted, and relative and absolute abundances were calculated. The relative abundances proved to be fairly reproducible, notwithstanding a need for taxonomic calibration. By contrast, excessive loss of Lycopodium spores during sample preparation resulted in non-reproducibility of absolute abundances. Use of oxidation, KOH, warm acids, acetolysis, mesh sizes larger than 15 µm and long ultrasonication (> 1 min) must be avoided to determine reproducible absolute abundances. The results of this work therefore indicate that the dinoflagellate cyst worker should make a choice between using the proposed standard method which circumvents critical steps, adding Lycopodium tablets at the end of the preparation and using an alternative method.

Data compilation on the biological response to ocean acidification: environmental and experimental context of data sets and related literature

The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

Dinocyst assemblages of site HM52-43

Past sea-surface conditions over the northern North Atlantic during the last glacial maximum were examined from the study of 61 deep-sea cores. The last glacial maximum time slice studied here corresponds to an interval between Heinrich layers H2 and H1, and spanning about 20-16 ka on a 14C time scale. Transfer functions based on dinocyst assemblages were used to reconstruct sea-surface temperature, salinity, and sea-ice cover. The results illustrate extensive sea-ice cover along the eastern Canadian margins and sea-ice spreading, only during winter, over most of the northern North Atlantic. On the whole, much colder winter prevailed, despite relatively mild conditions in August (10-15°C at most offshore sites), thus suggesting a larger seasonal contrast of temperatures than today. Lower salinity than at present is reconstructed, especially along the eastern Canadian and Scandinavian margins, likely because of meltwater supply from the surrounding ice sheets. These reconstructions contrast with those established by CLIMAP on the basis of planktonic foraminifera. These differences are discussed with reference to the stratigraphical frame of the last glacial maximum, which was not the coldest phase of the last glacial stage. The respective significance of dinocyst and foraminifer records is also examined in terms of the thermohaline characteristics of surface waters and the vertical structure of upper water masses, which was apparently much more stratified than at present in the northern North Atlantic, thus preventing deep-water formation.

Émergence et développement de l’oncologie au Québec : collaboration, compétition et défis organisationnels, 1900-2005

Objectifs : le principal objectif de notre projet doctoral consiste à mettre en relief les transformations qui ont marqué le développement de l’oncologie et de la lutte contre le cancer au Québec au 20e siècle. Pour ce faire, nous nous sommes penchées sur trois niveaux d’analyse : 1) le niveau micro aborde l’organisation des services médicaux au sein d’une organisation hospitalière, soit l’Hôtel-Dieu de Québec. 2) Le niveau méso analyse une lutte professionnelle, soit la lutte entre les hématologues et les oncologues médicaux pour la reconnaissance de l’oncologie médicale. 3) Le niveau macro s’intéresse à l’organisation de la lutte contre le cancer à travers la province de Québec et aux différents modèles organisationnels créés. Principale hypothèse : l’émergence et la transformation de l’oncologie et de la lutte contre le cancer ont été influencées des rapports de collaboration et de compétition entre les acteurs impliqués en oncologie. En effet, il apparaît que ce champ se trouve en tension entre l’obligation de collaborer pour offrir des services de qualité aux patients et les dynamiques professionnelles et/ou organisationnelles. Cadre théorique : un cadre théorique a été développé pour chacun des niveaux d’analyse. Le niveau micro s’inspire des travaux de Frickel, Abbott et Strauss et s’intéresse plus particulièrement aux négociations entourant l’ordre social au sein d’un hôpital universitaire; le niveau méso emploie les travaux de Bourdieu et Abbott pour analyser la lutte entre deux spécialités médicales pour le contrôle des agents de chimiothérapie; et le niveau macro, de la sociologie des organisations et de la théorie néo-institutionnaliste pour mettre en relief l’émergence et la transformation de la lutte contre le cancer au Québec au 20e siècle. Méthodologie : l’approche de l’étude de cas a été adoptée et chaque niveau d’analyse constitue une étude de cas à part entière. Le corpus de données se compose de données archivistiques recueillies dans 10 centres d’archives canadiens, et de données d’entrevues. Une soixantaine d’entrevues avec des oncologues, des professionnels de la santé, des gestionnaires, des chercheurs et des fonctionnaires ont été réalisées. Conclusion : les différents niveaux d’analyse offrent différentes contributions qui leurs sont propres, mais l’ensemble de la thèse tend à mettre en relief la complexité du changement organisationnel à travers un perpétuel processus de définition et de redéfinition des frontières professionnelles et des organisations en raison du développement des connaissances scientifiques, des technologies, des expertises professionnelles et de l’environnement social, politique et économique.

Dinoflagellate cysts in surface sediments

Surface sediments at 439 sites throughout the North Atlantic Ocean and adjacent seas have been analyzed for dinoflagellate cysts in order to establish a reference database from which paleoenvironmental transfer functions can be developed. Laboratory procedures and systematics were standardized in order to avoid bias introduced by the selective loss of taxa and to facilitate site to site comparison. 371 sites were retained to develop the database that includes 41 taxa, some of which were grouped using morphological and/or ecological criteria. 27 taxa were retained for statistical purposes. Distribution maps of these latter taxa have been plotted on the basis of their relative abundance. Principal component analyses were performed in order to describe the distribution of assemblages. The relation between the assemblages, as well as the relative abundance of individual taxa, and selected sea-surface parameters are illustrated. The parameters which were considered include temperature and salinity for winter (February) and summer (August) together with the duration of sea-ice cover. Transfer functions using the best analogue method have been tested with a view to reconstruct past sea-surface parameters. Validation procedures on this transfer function demonstrate that more than 95% of the reconstructions are included within the interannual variability of modern sea-surface conditions. Therefore, these transfer functions give accurate results and can be applied to reconstructing paleo-temperatures and -salinities from analogous assemblages in Quaternary sedimentary sequences. Protoperidinium stellatum (Wall in Wall & Dale, 1968) Head, comb. nov. (basionym = Peridinium stellatum) is proposed as new, and Algidasphaeridium? minutum var. cezare de Vernal et al., 1989 ex de Vernal et al. is newly validated.

El primer tropiezo histórico de Bonaparte: la reconquista de Santo Domingo

El objetivo de este trabajo es estudiar el primer tropiezo histórico de las tropas de Napoleón Bonaparte, en Santo Domingo, y los paralelismos entre la Guerra de Independencia española y la Reconquista dominicana. Para ello se han analizado los testimonios de los personajes implicados, con el fin de indagar el ideario que inspiró su acción militar. Además probaremos que, contra las ideas defendidas por algunos historiadores, tras la paz de Basilea los dominicanos siguieron sintiéndose ligados a España, como demostraron en la Guerra de Reconquista contra el gobierno francés. Sólo Cuba, Puerto Rico y Santo Domingo participaron de este sentimiento, mientras el resto de Hispanoamérica comenzaba a clamar por la independencia.

Crisis Económica en África Occidental: el caso de Dakar, 1929-1939

En este artículo se explora el impacto socio-económico de la crisis internacional de 1929 en Senegal y más concretamente en la ciudad-puerto de Dakar. Se analizan las consecuencias de la dependencia externa y la extroversión económica que caracterizaba a las estructuras productivas coloniales, destacando también la respuesta organizada de los movimientos sociales africanos. Por otra parte, se estudia la evolución de las infraestructuras y actividad portuaria, observando la metropolización regional de Dakar durante este periodo.

New constraints on European glacial freshwater releases to the North Atlantic Ocean

During the late Quaternary, both external and internal forcings have driven major climatic shifts from glacial to interglacial conditions. Nonlinear climatic steps characterized the transitions leading to these extrema, with intermediate excursions particularly well expressed in the dynamics of the Northern Hemisphere cryosphere. Here we document the impact of these dynamics on the north-eastern North Atlantic Ocean, focussing on the 35-10 ka interval. Sea-surface salinities have been reconstructed quantitatively based on two independent methods from core MD95-2002, recovered from the northern Bay of Biscay adjacent to the axis of the Manche paleoriver outlet and thus in connection with proximal European ice sheets and glaciers. Quantitative reconstructions deriving from dinocyst and planktonic foraminiferal analyses have been combined within a robust chronology to assess the amplitude and timing of hydrological changes in this region. Our study evidences strong pulsed freshwater discharges which may have impacted the North Atlantic Meridional Overturning Circulation.
