Phytoplankton dynamic in permanent and temporary waters of Empordà Salt marshes (NE Spain)

Se ha estudiado la dinámica del fitoplancton en las lagunas costeras de Aiguamolls de l'Empordà. El fitoplancton esta sujeto principalmente al control "bottom-up", la variabilidad hidrológica y la disponibilidad de nutrientes tienen una mayor influencia en la composición y distribución de tamaños del fitoplancton, que el zooplancton. La concentración de materia orgánica disuelta es el factor ambiental más correlacionado con el crecimiento de la biomasa fitoplanctónica. Dada la proximidad entre las lagunas costeras y el mar, donde la ocurrencia de Proliferaciones de Algas Nocivas es cada vez más frecuente, se realizan un inventario general de las especies más abundantes del fitoplancton y se llevan a cabo análisis extensivos de la toxicidad. La mayoría de especies de dinoflagelados encontradas son potencialmente nocivas. Hay pocas especies en común entre el mar y las lagunas, sin embargo, existen especies productoras de PANs características de los ambientes lagunares.

Recognizing emotion in illustrations and photographs: Comparing responses of children who are deaf or hard of hearing with those of children with normal hearing

Recognizing emotions are something children do everyday, whether it is identifying that mom is sad because she lost her job or that a character in a story is mad because no one will listen to him. The purpose of this study is to find out if recognizing emotions is easier to do with realistic photographs or illustrations.
