Ichthyofauna associated with Cymodocea nodosa meadows in the Canarian Archipelago (central eastern Atlantic): Community structure and nursery role

We carried out 84 trawls in 41 seagrass meadows composed of the phanerogam Cymodocea nodosa at three islands of the Canarian Archipelago, during June to September 2003, in order to describe the associated ichthyofauna (composition, richness, and abundance), to analyze the role that this habitat can play in fish recruitment, and to determine the potential relationship between the spatial structure of the seagrass meadow and the patterns of richness and abundance of the fish assemblage. A total of 8298 individuals were captured. The five most relevant species, in terms of abundance and frequency, were Spondyliosoma cantharus, Diplodus annularis, Syngnathus typhle, Mullus surmuletus, and Pagellus erythrinus. Gran Canaria had the largest species richness (36 species) and mean number of species per sample (8.69 ± 0.49; mean ± SE). Lanzarote had the largest number of individuals (64.83% of the total registered) and mean total abundance per sample (168.39 ± 30.91). High densities of individuals were registered (95.86 ± 13.5) and 92.91% of fishes were juveniles. Our data showed that the physical configuration of the seagrass meadows did not significantly affect the patterns of richness and abundance of the associated fish assemblage. In conclusion, the C. nodosa meadows exhibited a singular ichthyofauna and they contribute to the maintenance of the diversity of the coastal fish assemblages in the Canarian Archipelago. This habitat constitutes, during spring and summer, a nursery habitat for juvenile fishes of many species, several of them commercially targeted.

Insurrectos cubanos deportados hacia Canarias y Fernando Poo (1869): un ejemplo de deportación política

[ES] Aproximación a la deportación política: causas, circunstancias que la rodean y caracterización del fenómeno, para ello nos centramos en un proceso concreto: la deportación de insurrectos cubanos en 1869 con dirección a Fernando Póo y que afecta directamente a las Islas Canarias, lugar utilizado tradicionalmente como destierro. En este sentido, intentamos acercarnos a las controversias y reacciones que genera el fenómeno de la deportación, en la población, en general así como en los grupos de poder político de las islas, en particular.

Sobre Fernando Estévez y algunas esculturas del Niño Jesús. Nuevas atribuciones

[ES] La conmemoración del ccxxv aniversario del nacimiento de Fernando Estévez (1788-1854) en 2013 propició una aproximación diferente a la trayectoria de dicho artista. Este artículo recuerda las actividades organizadas entonces en La Orotava, especialmente una exposición de esculturas y documentos que tuvo varias sedes o lugares de exhibición durante el mes de marzo. Partiendo de obras contempladas entonces, se estudian otras representaciones del Niño Jesús que conservan templos del norte de Tenerife y pueden atribuírsele por cuestiones de estilo. [EN] The commemoration of 225th birth anniversary of Fernando Estévez (1788-1854) in 2013 allowed a new approach to his artistic caree. This paper recalls the activities organised in La Orotava back then, especially an exhibition of sculptures and documents in several spaces during the month of March. Based on the sculptures seen there, we can attribute to him other representations of the Infant Jesus that are preserved in churches in northern Tenerife.
