Ross Burns, Origins of the Colonnaded Streets in the Cities of the Roman East
Dans le prolongement des publications de W. L. MacDonald en 1986 et G. Bejor en 1999 , lâouvrage de Ross Burns intitulĂ© Origins of the Colonnaded Streets in the Cities of the Roman East est consacrĂ© Ă la genĂšse de la rue Ă colonnades et Ă la diffusion de ce type de rue dans lâOrient romain jusquâau dĂ©but du iiie s. ap. J.âC. Il sâorganise en trois parties. La premiĂšre est consacrĂ©e aux traditions architecturales susceptibles dâexpliquer lâapparition du type et aux cadres gĂ©nĂ©raux de lâamĂ©nag..

Distribution of cadmium in leaves of Thlaspi caerulescens
Knowledge of the intracellular distribution of Cd in leaves is necessary in order to understand the mechanisms of hyperaccumulation in Thlaspi caerulescens. Ganges and Prayon, two ecotypes accumulating Cd to different levels, were grown in nutrient medium containing varying concentrations (0, 5, 10, 50, and 100 ÎŒM) of Cd. Several different approaches were combined in this study to (i) validate the results obtained by a specific method and (ii) establish the link between observations and measurements performed at different scales. In both ecotypes, Cd, localized by autoradiography, was found mainly at the edges of the leaves, but also in points of higher concentration spread over the whole limb surface. This localization was clearly correlated with the necrotic spots observed on Prayon leaves. Scanning electron microscopy coupled with energy dispersive X-ray microanalysis (cryo-SEM-EDXMA) and tissue fractionation (apoplasm, cell walls, mesophyll protoplasts, and lower epidermis) showed that Cd had similar patterns of distribution in leaf cells of both ecotypes. Cadmium was found both inside the cells and in the cell walls, mainly in the large epidermal cells but also in small epidermal cells. All the methods used agreed well and the results indicated that metal storage in the plants studied involves more than one compartment and that Cd is stored principally in the less metabolically active parts of leaf cell
Using nonhuman culture in conservation requires careful and concerted action
Discussions of how animal culture can aid the conservation crisis are burgeoning. As scientists and conservationists working to protect endangered species, we call for reflection on how the culture concept may be applied in practice. Here, we discuss both the potential benefits and potential shortcomings of applying the animal culture concept, and propose a set of achievable milestones that will help guide and ensure its effective integration existing conservation frameworks, such as Adaptive Management cycles or Open Standards
