The Impact of Hurricane Georges on Soft-Bottom, Back Reef Communitites: Site- and Species-Specific Effects in South Florida Seagrass Beds

Seagrass beds are the dominant benthic marine communities in the back reef environment of the Florida Keys. At a network of 30 permanent monitoring stations in this back reef environment, the seagrass Thalassia testudinum Banks & Soland. ex Koenig was the most common marine macrophyte, but the seagrasses Syringodium fi liforme Kuetz., and Halodule wrightii Aschers., as well as many taxa of macroalgae, were also commonly encountered. The calcareous green macroalgae, especially Halimeda spp. and Penicillus spp., were the most common macroalgae. The passage of Hurricane Georges on September 25, 1998 caused an immediate loss of 3% of the density of T. testudinum, compared to 19% of the S. fi liforme and 24% of the calcareous green algae. The seagrass beds at three of the stations were completely obliterated by the storm. Stations that had little to moderate sediment deposition recovered from the storm within 1 yr, while the station buried by 50 cm of sediment and the two stations that experienced substantial erosion had recovered very little during the 3 yrs after the storm. Early colonizers to these severely disturbed sites were calcareous green algae. Hurricanes may increase benthic macrophyte diversity by creating disturbed patches with the landscape, but moderate storm disturbance may actually reduce macrophyte diversity by removing the early successional species from mixed-species seagrass beds.

The Uses of Print and Writing in Eighteenth Century European Ballet: the Case of The Letters on Dancing and Ballets by Jean-Georges Noverre

This article aims to study the uses of print, especially the Letters on Dancing and Ballets by Jean-Georges Noverre, throughout the emergence of pantomime ballet in the late eighteenth century. Noverre’s discourse is directly associated with a project to revitalize the art of dance. In this sense, books as an object are not only a support for the new aesthetic discourse, but a tool with multiple uses. It simultaneously seeks to modify the spectator’s view of the scene, legitimize the success of the new theatrical genre and value the ballet master profession.

La pintura que no se deja ver. La pintura avergonzada, la pintura escondida (a propósito de los escritos de Ángela de La Cruz, Georges didi-Huberman y Honoré de Balzac)

El artículo «La pintura que no se deja ver: la pintura avergonzada, la pintura escondida» relaciona una de las primeras obras de la artista Ángela de la Cruz ashamed (1995), con La pintura encarnada (1984) de Georges Didi-Huberman, ensayo que a su vez analiza La obra maestra desconocida (1837) de Honoré de Balzac. Entre Ángela de la Cruz, didi-Huberman y Balzac se establece un triángulo en torno al concepto cuadro-cuerpo. A través de una pintura, un ensayo filosófico y un relato, tres autores de tres tiempos distintos recuperan las mismas ideas de carne y piel pictórica y cuadro humanizado. Su objetivo: superar las barreras de representación en la pintura para crear un ser más allá del objeto pictórico. Sin embargo, cuanto más idealizan la pintura y más pretenden superar la pantallapictórica, más se desvanece el concepto de «cuadro»; cuanto más acercan el cuadro a ser, más se aleja de ser un cuadro y menos se permite el acceso a lo que representa. La persecución del ideal implica que el cuadro se vea sometido a su ocultación, al deterioro y a la destrucción de su imagen.

Dromoeconomics: Towards a Political Economy of Speed

In this article we present an alternative theoretical perspective on contemporary cultural, political and economic practices in advanced countries. Like other articles in this issue of parallax, our focus is on conceptualising the economies of excess. However, our ideas do not draw on the writings of Georges Bataille in The Accursed Share, but principally on Virilio’s Speed & Politics: An Essay on Dromology and Marx’s Capital and the Grundrisse.4 Using a modest synthesis of tools provided by these theorists, we put forward a tentative conceptualisation of ‘dromoeconomics’, or, a political economy of speed.

Isolation and characterisation of novel microsatellite and mitochondrial DNA markers for the Eastern Water Dragon (Physignathus lesueurii)

Habitat fragmentation as a result of urbanisation is a growing problem for native lizard species. The Eastern Water Dragon (Physignathus lesueurii) is a social arboreal agamid lizard, native to Australia. This species represents an ideal model species to investigate the effect of urbanisation because of their prominent abundance in the urban landscape. Here we describe the isolation and characterisation of a novel set of 74 di-, tri-, and tetramicrosatellites from which 18 were selected and optimised into two multiplexes. The 18 microsatellites generated a total 148 alleles across the two populations. The number of alleles per locus varied from 2 to 18 alleles and measures of Ho and He varied from 0.395 to 0.877 and from 0.441 to 0.880, respectively. We also present primers for four novel mitochondrial DNA (mtDNA) markers. The combined length of the four mtDNA marker pairs was 2,528 bp which included 15 nucleotides changes. In comparison to threatened species, which are generally characterised by small population sizes, the Eastern Water Dragon represents an ideal model species to investigate the effect of urbanisation on their behavioural ecology and connectivity patterns among populations.

Undrained sediment loading key to long-runout submarine mass movements : evidence from the Caribbean Volcanic Arc

Long undersea debris runout can be facilitated by a boundary layer formed by weak marine sediments under a moving slide mass. Undrained loading of such offshore sediment results in a profound drop of basal shear resistance, compared to subaerial shear resistance, enabling long undersea runout. Thus large long-runout submarine landslides are not truly enigmatic (Voight and Elsworth 1992, 1997), but are understandable in terms of conventional geotechnical principles. A corollary is that remoulded undrained strength, and not friction angle, should be used for basal resistance in numerical simulations. This hypothesis is testable via drilling and examining the structure at the soles of undersea debris avalanches for indications of incorporation of sheared marine sediments, by tests of soil properties, and by simulations. Such considerations of emplacement process are an aim of ongoing research in the Lesser Antilles (Caribbean Sea), where multiple offshore debris avalanche and dome-collapse debris deposits have been identified since 1999 on swath bathymetric surveys collected in five oceanographic cruises. This paper reviews the prehistoric and historic collapses that have occurred offshore of Antilles arc islands and summarizes ongoing research on emplacement processes.
