Special Issue Information

Dear Colleagues,

The main goal of freshwater monitoring is to provide knowledge about the biological and chemical conditions of these ecosystem. Freshwater monitoring is necessary for the sustainable management of water resources, including protection against eutrophication, preservation of biodiversity and anthropogenic pollution. In the 21st century, inland water ecosystems are under intense pressure from climate change, especially the occurrence of extreme weather phenomena (long-term droughts, torrential rainfall, disturbances in the water balance, etc.). All these stressors have a negative impact on natural habitats, causing the retreat of sensitive species and the emergence of invasive alien species. Hence, constant monitoring of habitats and species may play a significant role as a part of the rapid response system to adverse changes in freshwater environments.

This Special Issue invites fundamental, experimental, and case study-based studies focused on the relationships between anthropogenic stressors and inland water biocenosis (microorganisms, macrophytes, plankton, benthos, fish), including biotic indices used for freshwater monitoring and proposals of new methods. Studies on rare and endangered or invasive species and their impact on diversity of native species are of high interest.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The occurrence of the protected species Castor fiber L., which creates a network of natural barriers for its own needs, may affect the changes in water quality parameters. This study shows changes in the water quality parameters (EC, BOD5, COD, TN, N-NH4, N-NO3, N-NO2, TP, P-PO4, Cl−, SO42−) of small rivers in eastern Poland. The results were analysed using the one-way and three-way ANOVA Tukey’s HSD post hoc test to identify the significance of the changes in the water quality parameters for habitats, seasons, and land use. All parameters, with the exception of P-PO4, met the standards of a good ecological status. The average values of P-PO4 exceeded the threshold of the good ecological status in summer and meadows. The average annual changes in the water quality parameters, with the exception of N-NH4, are characterised by a decrease in pollution. The highest concentration decrease of 57% was found for P-PO4 and 45% for TP at the sites after the barriers. The lowest concentration decrease of 5% was found for EC. In the case of N-NH4, the concentration increase was 33%. The situation was completely different in the case of removing barriers, where an increase in the concentration of pollutants of about 30% was found. Changes in the water quality were significantly influenced by the season and land use. Due to the various construction, age, and removal of the barriers, beaver habitats may positively or negatively impact the water quality. It is crucial for the improvement of the water quality to ensure the durability of the functioning of barriers and the proper use of the land. Full article

The influence of water brownification (an increase in water color) on floating-leaved macrophytes appears to be an important issue in predicting the consequences of climate change in freshwater ecosystems. To fill the gap in the knowledge in this area, we performed a laboratory experiment aiming to test the impact of humic acid (HA) on Lemna minor sampled from an oxbow lake. Plants were exposed over seven days to four different additions of pure HA (resulting in DOC concentrations between 5.0 ± 0.1 mg dm−3 and 36.5 ± 0.4 mg dm−3). Changes in duckweed total fresh biomass, leaf area and the root length were measured, as well as the concentrations of total phosphorus, phosphates and nitrates in the water. The study did not find any significant decrease in either the biomass or leaf area of L. minor under conditions of enhanced HA content. However, we found that a moderate increase in HA in water promoted the growth of duckweed roots, thus, increasing the biomass but not the leaf area. In contrast, a large increase in HA in the water suppressed the growth of roots in L. minor, which was also in coincidence with less nutrient depletion in the water. Full article
