Title: Study of N and C cycles and the effect of UV radiation on microbial Antarctic communities
Description:
Abstract:
IN ENGLISH: The data collected were: -Study of the UV natural radiation effect on 3 different communities using filters with different wide radiation strip. -Samples to determinate the effect on the pigment composition, as photosynthetic character as photo-protector, just as in the community structure. -Study of the UV radiation effect on the rotifere population. -Experiment of the UV radiation effect on the artificial colonization of an artificial substrate with cyanobacterial microbial makers. -Study of the N cycle in different lakes -Descriptive study of different communities, with samples of each community, making for each community, microscopically studies of the species. EN ESPANOL: Los datos recogidos fueron: -Estudio del efecto de la radiacion UV natural en tres comunidades diferentes utilizando filtros con diferente ancho de banda de radiacion. -Muestras para la determinacion de los efectos en la composicion pigmentaria, tanto de caracter fotosintetico como fotoprotector, asi como en la estructura de la comunidad. -Estudio sobre el efecto de la radiacion UV en las poblaciones de rotiferos -Experimento del efecto de la radiacion UV en la colonizacion de un sustrato artificial por parte de cianobacterias formadoras de tapetes microbianos. -Estudio del ciclo de N en diferentes lagos. -Estudio descriptivo de diferentes comunidades, con muestras de cada comunidad realizandose estudios microscopicos de especies de cada comunidad.
