UV effects on invertebrate and diatom assemblages of Greece.
The effects of solar radiation (PAR, UVA, UVB) on the productivity and structure of diatom and invertebrate assemblages were assessed during primary succession on artificial substrate near a rocky shore of the Saronikos Gulf, Greece. Three light treatments were performed (PAR, PAR+UVA, and PAR+UVA+UVB) at 0.5, 1.0 and 1.5 m of depth. Pennate diatoms were the major component of the developing pe...
متن کاملA comparison of diatom assemblages generated by two sampling protocols
We investigated whether 2 stream sampling protocols collected different diatom assemblages within sampling reaches and, consequently, influenced the outcome of bioassessment. We analyzed data collected at 71 sites by both reach-scale (Environmental Monitoring and Assessment Program [EMAP]) and targeted-habitat (US Environmental Protection Agency [EPA] Science to Achieve Results [STAR]) sampling...

15 صفحه اولUVB radiation and depth interaction during primary succession of marine diatom assemblages of Greece
Exposure to UVB radiation caused shifts in the species composition of diatom assemblages developing on ceramic tiles in a natural marine habitat near Korinthos, Greece. These differences in community structure were more pronounced during the first month of community development. The diatom species Mastogloia crucicula and Nitzschia constricta were sensitive to both UVA and UVB radiation, while ...
متن کاملDo benthic diatom assemblages refl ect abiotic typology: a case study of Croatian streams and rivers
Benthic diatoms are widely used in Europe and worldwide to access ecological status of running waters. One of key goals of Water Framework Directive is to classify rivers and streams using biological quality elements and type specifi c reference conditions. According to system B which incorporates additional abiotic descriptors, there are 24 water types in Croatia. For biological analyses 92 ri...
