Proteomics in Seaweeds: Ecological Interpretations

摘要: Macro and micro-algae are fundamental components of coastal benthic ecosystems responsible for a large part the primary production (Lobban & Harrison, 1994). Adverse effects on these groups caused by natural or anthropogenic phenomena, can affect directly indirectly organisms higher trophic levels integrity entire ecosystems. In this context, both ecological economic importance many algal species justifies need to expand our knowledge molecular biology organisms. The distribution abundance occurring in marine zone results from interplay biotic (i.e. competition herbivore pressure) abiotic tolerance extreme fluctuating environments) factors (Abe et al., 2001; Burritt 2002; Davison Pearson, 1996; Pinto 2003; van Tamelen, 1996). For example, macroalgal at upper limit rocky intertidal is principally determined such as UV radiation, light, salinity, temperature changes, nutrient availability desiccation (e.g. Aguilera Cabello-Pasini 2000; Contreras-Porcia 2011a; Veliz 2006). On other hand, microalgae diversity maintained combination variable forces - environmental oscillations habitat instability), more severe disturbances recovery catastrophic forcing backed powerful dispersive mobility group (Reynolds, richness, relative occasional dominances phytoplankton successive years, depends water movements, thermal stress carbon fluxes, but mainly enrichment sea (Hodgkiss Lu, 2004; Holm-Hansen Reynolds, 2006; Wang Zurek Bucka, 2004). Superimposed oscillations, algae also exposed various sources stress, particularly those resulting human industrial, urban agricultural activities.
