Charting Cartographies of Resistance: Line of Flight in Women Artists’ Narratives

In this paper I chart lines of flight in women artist’s narratives. In focusing on the complex interrelations between the social milieus of education and art, what I suggest is that they should be analysed as an assemblage where power relations and forces of desire are constantly at play in creating conditions of possibility for women to resist, imagine themselves becoming other and for new possibilities in their lives to be actualised. As a novel approach to social ontology the theory of assemblages offers an analytics of social complexity that accounts for open configurations, continuous connections and unstable hierarchies, structures and axes of difference. In reconsidering resistance as immanent in dispositifs of power and assemblages of desire, what I finally argue is that women artists’ narratives contribute to the constitution of minor knowledges and create archives of radical futurity.

Paléoécologie du Quaternaire dans la région de Wainwright en Alberta

En 2012, la Commission géologique du Canada a procédé à une série de forages dans les dépôts quaternaires de la région de Wainwright dans le centre-est de l’Alberta dans le cadre d’un projet en hydrogéologie. Les forages, qui atteignent plus de 60 m de profondeur, montrent la présence de niveaux organiques intercalés dans les unités stratigraphiques minérales, dont certains contiennent des morceaux de bois qui suggèrent la présence passée in situ d’une végétation ligneuse. La position stratigraphique des sables contenant des niveaux organiques sous le till régional (Wisconsinien supérieur) laisse penser qu’ils correspondraient à des épisodes interstadiaires, voire même de l’interglaciaire Sangamonien, des datations 14C ayant livré des âges non-finis (>43 500 ans A.A.). L’objectif principal de la présente étude était de documenter la composition du couvert végétal associé aux niveaux organiques à l’aide de l’analyse pollinique et macrofossile. Plusieurs des niveaux se sont avérés pauvres ou même stériles en grains de pollen et en macrorestes végétaux. Les assemblages polliniques sont le plus souvent dominés par des espèces herbacées (p. ex.: Cyperaceae, Artemisia sp.) et des fougères. Chez les arbres, l’épinette est l’espèce la mieux représentée mais elle montre des pourcentages polliniques relativement faibles. Les assemblages macrofossiles sont notamment caractérisés par la présence de matière ligneuse, de l’épinette et de plantes aquatiques. Plusieurs échantillons contiennent aussi des charbons de bois qui témoignent de l’incidence de feux. Les résultats des analyses paléoécologiques suggèrent que le couvert végétal contemporain du dépôt des niveaux organiques était à caractère boréal ouvert. Ces niveaux auraient donc été mis en place au cours d’un intervalle climatique plus froid que l’actuel, présumément un interstade wisconsinien plutôt qu’au cours du dernier interglaciaire (Sangamonien).

Identification of bacteria associated with Dinoflagellates (Dinophyceae) Alexandrium spp. using tyramide signal amplification fluorescent in situ hybridization and confocal microscopy

In the marine environment, phytoplankton and bacterioplankton can be physically associated. Such association has recently been hypothesized to be involved in the toxicity of the dinoflagellate genus Alexandrium. However, the methods, which have been used so far to identify, localize, and quantify bacteria associated with phytoplankton, are either destructive, time consuming, or lack precision. In the present study we combined tyramide signal amplification–fluorescent in situ hybridization (TSA-FISH) with confocal microscopy to determine the physical association of dinoflagellate cells with bacteria. Dinoflagellate attached microflora was successfully identified with TSA-FISH, whereas FISH using monolabeled probes failed to detect bacteria, because of the dinoflagellate autofluorescence. Bacteria attached to entire dinoflagellates were further localized and distinguished from those attached to empty theca, by using calcofluor and DAPI, two fluorochromes that stain dinoflagellate theca and DNA, respectively. The contribution of specific bacterial taxa of attached microflora was assessed by double hybridization. Endocytoplasmic and endonuclear bacteria were successfully identified in the nonthecate dinoflagellate Gyrodinium instriatum. In contrast, intracellular bacteria were not observed in either toxic or nontoxic strains of Alexandrium spp. Finally, the method was successfully tested on natural phytoplankton assemblages, suggesting that this combination of techniques could prove a useful tool for the simultaneous identification, localization, and quantification of bacteria physically associated with dinoflagellates and more generally with phytoplankton.

A Community-Level, Mesoscale Analysis of Fish Assemblage Structure in Shoreline Habitats of a Large River Using Multivariate Regression Trees.

The mesoscale (100–102 m) of river habitats has been identified as the scale that simultaneously offers insights into ecological structure and falls within the practical bounds of river management. Mesoscale habitat (mesohabitat) classifications for relatively large rivers, however, are underdeveloped compared with those produced for smaller streams. Approaches to habitat modelling have traditionally focused on individual species or proceeded on a species-by-species basis. This is particularly problematic in larger rivers where the effects of biological interactions are more complex and intense. Community-level approaches can rapidly model many species simultaneously, thereby integrating the effects of biological interactions while providing information on the relative importance of environmental variables in structuring the community. One such community-level approach, multivariate regression trees, was applied in order to determine the relative influences of abiotic factors on fish assemblages within shoreline mesohabitats of San Pedro River, Chile, and to define reference communities prior to the planned construction of a hydroelectric power plant. Flow depth, bank materials and the availability of riparian and instream cover, including woody debris, were the main variables driving differences between the assemblages. Species strongly indicative of distinctive mesohabitat types included the endemic Galaxias platei. Among other outcomes, the results provide information on the impact of non-native salmonids on river-dwelling Galaxias platei, suggesting a degree of habitat segregation between these taxa based on flow depth. The results support the use of the mesohabitat concept in large, relatively pristine river systems, and they represent a basis for assessing the impact of any future hydroelectric power plant construction and operation. By combing community classifications with simple sets of environmental rules, the multivariate regression trees produced can be used to predict the community structure of any mesohabitat along the reach.

Palaeontological data about the climatic trends from Chattian to present along the Northeastern Atlantic frontage

Climatic changes that affected the Northeastern Atlantic frontage are analyzed on the basis of the evolution of faunas and floras from the late Oligocene onwards. The study deals with calcareous nannoplankton, marine micro- and macrofaunas, some terrestrial vertebrates and vegetal assemblages. The climate, first tropical, underwent a progressive cooling (North-South thermic gradient). Notable climatic deteriorations (withdrawal towards the South or disappearance of taxa indicative of warm climate and appearance of "cold" taxa) are evidenced mainly during the Middle Miocene and the late Pliocene. Faunas and floras of modern pattern have regained, after the Pleistocene glaciations, a new climatic ranging of a temperate type in the northern part.
