A fotografia compromissada na espanha: a experiência de Josep Renau nas revistas Orto e Octubre

The aim of this paper is to investigate the environment in which a proposal for photographs and photo montages created in Spain in the 1930s was developed. To achieve this, the experiences of the Spanish artist Josep Renau and his work in the illustrated magazines Orto and Octubre is examined. There is an attempt to explore how the European experience of proletarian culture and photography was circulated and appropriated by the Spanish cultural universe. I believe that during these years Spain became a production hub and disseminator of political iconography which later spread to Mexico and Latin America.

Climatic and stratigraphic paleoindicators from the Canary Island

[EN] The last 5 Myr  are characterized by cliamatic variations globally and are reflected in ancient fossiliferous marine deposits visible in the Canary Islands. The fossils contained are identificated as paleoecological and paleoclimatic indicators. The Mio-Pliocene Transit is represented by the coral Siderastrea micoenica Osasco, 1897; the gastropods Rothpletzia rudista Simonelli, 1890; Ancilla glandiformis (Lamarck, 1822); Strombus coronatus Defrance, 1827 and Nerita emiliana Mayer, 1872 and the bivalve Gryphaea virleti Deshayes, 1832 as most characteristic fossils  and typical of a very warm climate and littoral zone. Associated  lava flows  have been dated radiometrically  and provides a range between  8.9 and about 4.2 Kyr. In the mid-Pleistocene, about 400,000 years ago, the called Marine Isotope Stage 11, a strong global warming that caused a sea level rise happens. Remains of the MIS 11  are preserved on the coast of Arucas (Gran Canaria), and associated with a tsunami in Piedra Alta (Lanzarote). These fossilifeorus  deposits contains the bivalve Saccostrea cucullata (Born, 1780), the gastropod Purpurellus gambiensis (Reeve, 1845) and the corals Madracis pharensis (Heller, 1868) and Dendrophyllia cornigera (Lamarck, 1816). Both sites have been dated by K-Ar on pillow lavas (approximately 420,000 years) and by Uranium Series on corals (about 481,000 years) respectively. The upper Pleistocene starts with another strong global warming known as the last interglacial or marine isotope  stage (MIS) 5.5, about 125,000 years ago, which also left marine  fossil deposits exposed in parallel to current in Igueste of San Andrés (Tenerife),  El Altillo, the  city of Las Palmas de Gran Canaria  and Maspalomas (Gran Canaria),  Matas Blancas, the Playitas and Morrojable (Fuerteventura ) and in Playa Blanca and Punta Penedo (Lanzarote ). The fossil coral Siderastrea radians (Pallas , 1766 ) currently living in the Cape Verde Islands , the Gulf of Guinea and the Caribbean has allowed Uranium series dating. The gastropods Strombus bubonius Lamarck, 1822 and Harpa doris (Röding , 1798 ) currently living in the Gulf of Guinea. Current biogeography using synoptic data obtained through satellites provided by the ISS Canary Seas provides data of Ocean Surface Temperature (SST) and Chlorophyll a (Chlor a) . This has allowed the estimation of these sea conditions during interglacials compared to today .

Aves marinas (Procellariidae) del Pleistoceno del yacimiento paleontológico de la Montaña de Timbaiba (Lanzarote, Islas Canarias)

[ES] Se describe la concurrencia de restos fósiles pertenecientes a dos taxones avianos de pardelas (Procellariidae) provenientes del yacimiento paleontológico de Montaña de Timbaiba, del Pleistoceno Medio, en la isla de Lanzarote. El conjunto está copado mayoritariamente por la especie extinta Puffinus holeae y se constata la presencia de la especie actual Calonectris diomedea. Se interpreta el yacimiento como un posible lugar de nidificación y cría de estas especies de pardelas.

Patrimonio paleontológico y arqueológico de la desembocadura del Barranco de Jinámar, Playa de Bocabarranco (Telde, Gran Canaria)

[ES]Canarias es un lugar natural privilegiado. Esta afirmación adquiere más consistencia si se constata que ello se remonta hasta las primeras fases de la formación de las islas en donde los principales eventos climáticos de los últimos 24 millones de años a escala global, han quedado reflejados en forma de paleotestimonios marinos y terrestres. A este patrimonio natural de gran importancia científica, se le suma un rico patrimonio arqueológico proveniente de los antiguos pobladores de Canarias. En algunos puntos muy concretos, en una superficie muy pequeña, encontramos restos arqueológicos y testimonios paleoclimáticos. Uno de estos puntos se localiza en la costa este de Gran Canaria, en la desembocadura del Barranco de Jinámar, término municipal de Telde.
