Macrophyte meadows mediate the response of the sediment microbial community to ultraviolet radiation

چکیده
Abstract The decrease of the water level in Mediterranean wetlands due to global warming allows UVR reach sediment microbial community. Macrophyte meadows, through their structure and compounds contribution, exert influence on this Our goal was establish how community a wetland is harmed by UVR, macrophytes mitigate such effects. We performed field factorial experiment (UVR as factors) wetland. abundance composition (bacteria, Archaea, microalgae cyanobacteria) stoichiometry superficial sub-superficial layers were analysed. altered even small doses coastal decreasing periphyton abundance, including bacteria involved C N metabolism. Submerged favoured periphytic biofilm increased carbon nitrogen amounts, promoting cycles. shade exerted meadows minimized effects, driving similar that UVR-filtered environment. Therefore, macrophytes, different mechanisms, can harmful effects communities. Thus, conservation macrophyte highly vulnerable becomes crucial change context.

The responses of heterotrophic microbial food webs (HMFW) to the joint action of abiotic stressors related to global change have been studied in an oligotrophic high-mountain lake. A 2×5 factorial design field experiment performed with large mesocosms for >2 months was used to quantify the dynamics of the entire HMFW (bacteria, heterotrophic nanoflagellates, ciliates, and viruses) after an expe...
