Little is known about the low dose effects of radiation on microbial communities in the environment. This study used DNA metabarcoding to investigate the genetic richness, diversity, and structure of diatom communities in 16 mineral springs in the Massif Central, France, and found that geographical location and 238U were the main factors influencing ASVs distribution and diatom ASV structure. The genetic variant of Planothidium frequentissimum associated with high levels of 238U may serve as a bio-indicator of high natural uranium levels.
Little is still known about the low dose effects of radiation on the microbial communities in the environment. Mineral springs are ecosystems than can be affected by natural radioactivity. These extreme environments are, therefore, ob-servatories for studying the influence of chronic radioactivity on the natural biota. In these ecosystems we find dia-toms, unicellular microalgae, playing an essential role in the food chain. The present study aimed to investigate, using DNA metabarcoding, the effect of natural radioactivity in two environmental compartments (i.e. spring sedi-ments and water) on the genetic richness, diversity and structure of diatom communities in 16 mineral springs in the Massif Central, France. Diatom biofilms were collected during October 2019, and a 312 bp region of the chloroplast gene rbcL (coding for the Ribulose Bisphosphate Carboxylase) used as a barcode for taxonomic assignation. A total of 565 amplicon sequence variants (ASV) were found. The dominant ASV were associated with Navicula sanctamargaritae, Gedaniella sp., Planothidium frequentissimum, Navicula veneta, Diploneis vacillans, Amphora copulata, Pinnularia brebissonii, Halamphora coffeaeformis, Gomphonema saprophilum, and Nitzschia vitrea, but some of the ASVs could not be assigned at the species level. Pearson correlation failed to show a correlation between ASV' richness and radioactivity parameters. Non-parametric MANOVA analysis based on ASVs occurrence or abundances revealed that geographical location was the main factor influencing ASVs distribution. Interestingly, 238U was the second factor that explained diatom ASV structure. Among the ASVs in the mineral springs monitored, ASV associated with one of the genetic variants of Planothidium frequentissimum was well represented in the springs and with higher levels of 238U, suggesting its high tolerance to this particular radionuclide. This diatom species may therefore represent a bio-indicator of high natural levels of uranium.

Sagova-Mareckova, J. K. Pearman, X. Pochon, T. Stoeck, R. Vivien, A. Weigand, S. Fazi

Summary: Environmental DNA (eDNA) metabarcoding is transforming aquatic biomonitoring by sequencing DNA/RNA to identify entire communities within a targeted group. Most studies have focused on water eDNA and macroinvertebrate samples, but eDNA metabarcoding has also been applied to soft sediment samples, especially for microbial or meiofaunal communities. Compared to traditional methods, eDNA metabarcoding offers advantages for assessing sediment environmental quality. However, there is a need for standardization to improve robustness and comparability. This review focuses on sampling, preservation, and DNA extraction protocols for sediment eDNA metabarcoding, aiming to identify best practices and promote harmonization for future benthic monitoring.

Composition, structure, and distribution of diatom assemblages in Mediterranean thermal spring ecotones affected by natural and human disturbances

Giuseppina G. Lai, Carlos E. Wetzel, Luc Ector, Antonella Luglie, Bachisio M. Padedda

Summary: This study analyzed diatom assemblages in thermal springs in Sardinia, Italy, and found that low discharge, ecotonal properties, and natural and human disturbances significantly affect the composition of the aquatic communities. Springs connected to rivers and with higher disturbance levels exhibited higher species richness and diversity, while isolated springs harbored smaller pools of taxa with specific habitat preferences or restricted distributions. Environmental variables such as water temperature, river influence, and nutrients also played a major role in shaping the diatom assemblages.

Adlafia kociolekii sp. nov. (Bacillariophyceae): a new naviculoid diatom from the Eastern Himalayas, India

Cheran Radhakrishnan, Sudipta Kumar Das, Carlos E. Wetzel, Balasubramanian Karthick

Summary: We describe a new species of Adlafia called Adlafia kociolekii from aerial habitats in Sikkim, India. The species was observed and described based on light and scanning electron microscopy observations. The main diagnostic features of this species include clear elliptical valves, a narrow axial area at the centre, radiate to convergent striation, and a distinctive Voigt discontinuity at both apices. The ultrastructure of this species, including the presence of a raphe on the elevated sternum, distal raphe ends deflected to opposite sides of proximal ends, and distal ends terminating in long and thickened helictoglossae, distinguishes it as a new species. The species was also found in wet walls and freshwater habitats in northeast India. Morphological features of this species were compared with closely similar taxa of Adlafia and other naviculoid genera.

Summary: The study investigated the ability of bacteria in wastewater treatment plant (WWTP) outflows to colonize rock surfaces and contribute to the formation of river epilithic biofilms. The bacterial communities of biofilms developing on rocks exposed to treated wastewaters (TWW) from a hospital and a domestic clarifier, as well as surface waters of the stream at different distances from the WWTP outlet, were compared. The results revealed differences in bacterial contents and species composition among the biofilms depending on the source of treated wastewater. The analysis also highlighted the presence of multi-resistant bacteria and correlations between bacterial species and pharmaceutical concentrations in the biofilms.

Surya Gupta, Pasquale Borrelli, Panos Panagos, Christine Alewell

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
