Abstract

Field observations form the basis of the majority of studies on microphytobenthic algal communities in freshwater ecosystems. Controlled mesocosm experiments data are comparatively uncommon. The few experimental mesocosm studies that have been conducted provide valuable insights into how multiple stressors affect the community structures and photosynthesis-related traits of benthic microalgae. The recovery process after the stressors have subsided, however, has received less attention in mesocosm studies. To close this gap, here we present the results of a riparian mesocosm experiment designed to investigate the effects of reduced flow velocity, increased salinity and increased temperature on microphytobenthic communities. We used a full factorial design with a semi-randomised distribution of treatments consisting of two levels of each stressor (2 × 2 × 2 treatments), with eight replicates making a total of 64 circular mesocosms, allowing a nuanced examination of their individual and combined influences. We aimed to elucidate the responses of microalgae communities seeded from stream water to the applied environmental stressors. Our results showed significant effects of

Abstract

[Display omitted] • The benthic community in the Sava River was predominantly colonized by pennate diatoms. • In the benthic community in the Tisa River centric diatoms were predominant. • rbcL marker provided a comprehensive view of the diatom community. • Presence/absence of taxa assessed with rbcL to assess water quality of large lowland rivers proved more similar to morphological identification. This study examines the effectiveness of digital microscopic and molecular analysis (rbcL and 18S markers) in assessing diatom community composition and water quality in two international rivers (Sava and Tisa rivers). Also, two different approaches were applied for calculating diatom indices: based on the relative abundance of taxa and the presence/absence of taxa. The rbcL marker showed up as a more suitable choice for providing a comprehensive view of the diatom community compared to 18S, which can be partly attributed to variations in the coverage of reference databases. Furthermore, both morphological and molecular analysis pointed out statistically different ecological statuses of investigated rivers. Diatom indices derived from molecular data indicated one or two classes of lower ecological status than those based on morphological analysis. However, the average diatom indices derived from molecular presence/absence data were higher than those based on the relative abundance of taxa. After summarizing all the results, we can recommend using the rbcL marker with taxa presence/absence data for routine monitoring of large lowland rivers. [ABSTRACT FROM AUTHOR]
