Breves notas sobre plantas y comunidades de Gran Canaria

En este artículo se describen varias comunidades de plantas en Gran Canaria, especialmente las procedentes de playas y otros lugares de la zona SE de la isla. También se hacen comentarios sobre la presencia reciente de alguna especie hasta el momento no registrada en el territorio recorrido, como Limnoniastrum monopetalum. Se estudian algunas asociaciones nitrófilas y otras de los depósitos arenosos de la desembocadura de la rambla de Jinamar. También la expansión de alguna especie de acacias en las dunas de Maspalomas. Se da a conocer una nueva asociación cerca de la playa de San Agustín: A triplici-Amaranthetum gracilis, muy extendida por la zona estudiada.

The photography and the motion landscape in the urban expressway

A new kind of photographic representation, called movement-image is proposed and discussed to record the visual experience of the journey through urban highways. It consists of performing long exposure photographic shots while the track is traversed, thus registering a time-panorama which includes landscape signs and inner spaces of the ways involved. This proposal is linked to the limitations of representing these expressways, if they are understood as structures of instrumental origin, where the resulting experience comes from moving at high speed through the territory. In al almost all cases the aesthetic approach or urban integration with the city and landscape are excluded. In this sense, although such structures may be an opportunity to collect, build and colonize the urban landscape, the lack of adequate representation of the phenomenon causes a difficulty in its understanding and transformation. The options for representation using photography is assumed, knowing its own particular tradition in the use of long exposures, for the expression of the mobile, and the multiple visual attention, divided or weakened.
