Ecological status of Urdaibai Biosphere reserve based on bacterial communities in a small-drainage estuary

چکیده
Context The influence of anthropogenic pressures on plankton communities in well-flushed estuaries has been overlooked. Owing to this ecosystem’s short water-residence time, they are foreseen be mainly composed microorganisms from neritic–oceanic sources, more resilient impacts. Aims This study characterises the bacterioplankton Urdaibai, a small-drainage estuary located at UNESCO biosphere reserve, unravel its annual dynamic and ecological status. Methods Amplicon sequencing was used assess euhaline shifts microgAMBI index depicted status estuary. Key results A differentiated community identified upstream waters throughout year. In addition, organisms commonly associated with faecal waste were detected. poor or moderate along cycle, but surprisingly worsened during winter. Conclusions above suggests that bacterial well-fluxed is complex than anticipated. Importantly, analysis pollution-indicative bacteria proved water policy needs further evaluated. Implications completion an efficient sewage treatment system for protected touristic strongly recommended. Incorporating information current monitoring will constitute useful valuable tool.

متن کاملUsing ecological diversity measures with bacterial communities.
Abstract There are many ecological diversity measures, but their suitability for use with highly diverse bacterial communities is unclear and seldom considered. We assessed a range of species richness and evenness/dominance indices, and the use of species abundance models using samples of bacteria from zinc-contaminated and control soils. Bacteria were assigned to operational taxonomic units (O...
