The impact of different surface parameterizations and vertical resolutions on the simulation of seabreeze episodes at the island of Fuerteventura

[EN] On 8-10 April 2007, several episodes of intense sea-breeze fronts were registered at the island of Fuerteventura (Canary Islands). The sea-breeze circulation was primary driven by daytime heating contrasts between land and the Atlantic Ocean during a period of weak trade winds. Numerical simulations of these events were carried out using the 3.1.1 version of the Weather Research and Forecasting (WRF) Model. Two different domains with 6.6-km and 2.2-km horizontal grid spacing and two sets with 27 and 51 vertical sigma levels were defined. The simulation was performed using two-way interactive nesting between the first and the second domain, using different land surface model parameterizations (Thermal diffusion, Noah LSM and RUC) for comparison. Initial conditions were provided by the NCAR Dataset analysis from April 2007, which were improved using surface and upper-air observations. The poster is focused on the 9 April episode.

Influencia de la temperatura en el comportamiento y color de Palaemon elegans (Rathke, 1837) (Crustacea, Decapoda)

[ES] El camarón de charco (Palaemon elegans) soporta altos rangos de temperatura, pero a medida que ésta baja (hasta 5 ºC) comienza a reducir sus movimientos hasta quedar completamente inmóvil, casi en letargo. A este cambio de comportamiento va unido un cambio en la coloración del cuerpo del animal, que pasa de ser completamente transparente con tonos vivos azules y amarillos a ser translúcido, con azules y amarillos mucho más pálidos

Comportamiento de apoyo social en especies territoriales: "Parablennius parvicornis" (Valenciennes, 1836) y "Mauligobius maderensis" (Valenciennes, 1837)

[ES] Se estudia el comportamiento de apoyo social entre individuos de dos especies de peces territoriales (Parablennius parvicornis y Mauligobius maderensis) ante una situación de estrés. Se observa que a medida que la densidad de individuos aumentaba el estrés respiratorio en los individuos disminuía.
