Special Issue Information

Dear Colleagues,

It is well known that the biodiversity of freshwater ecosystems has suffered heavily decline in recent decades. Although, we are aware of these processes, further decreases in valuable ecosystems and the biodiversity therein are occurring in our neighbourhoods. Aquatic ecosystems are some of the fastest disappearing habitats on Earth. Various human pressures on aquatic ecosystems have posed a permanent threat despite the regulations and numerous attempts to protect them. However, the conservation of freshwater ecosystems and their biodiversity is not just our obligation to future generations but also a strategic issue that can influence our quality of living. With reduced biodiversity in freshwater ecosystems, their resilience decreases and vulnerability to various pressures increases. Their self-purifying capacity and ability to mitigate extreme events, such as floods, are also reduced. The consequences of climate changes also include altered hydrological regimes of superficial and underground freshwaters, which can fatally influence the citizens living in their catchment areas. The conservation of biodiversity in freshwater ecosystems depends on their suitable management, which could also solve several issues on flood risk mitigation and drinking water supply. We would like to gather contributions dealing with different aspects of biodiversity of freshwaters and including suggestions for their proper management to reach conservation goals and enhance human well-being at the same time.

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.

The diversity of macrophytes and macroinvertebrates in small standing waters of different origins and characteristics was investigated. This survey covered 19 ponds in the Drava field in northeastern Slovenia. The influence of the macrophytes on the macroinvertebrates was investigated and the main environmental factors that had the most significant influence on the composition of the two communities were identified. Sixty-seven taxa of macrophytes and seventy-three families of macroinvertebrates were identified. We found that a diverse macrophyte community has a positive effect on the macroinvertebrate community. In contrast, the dominance of a single macrophyte species has a strong negative influence on the richness of the macroinvertebrate community. The taxonomic richness and abundance of the macroinvertebrate community in the natural ponds was statistically significantly higher than that in artificial ponds. The significant differences in the environmental characteristics between the natural and artificial ponds, such as the macrophyte cover, conductivity, and riparian zone width, may account for these differences. Our study suggests that a greater diversity of macrophyte and macroinvertebrate communities in natural ponds is enabled by abundant but diverse macrophyte cover, low phosphorus content, and wide riparian zones, which require appropriate management of ponds and their catchments.
