“…Secchi disc visibility was also used in the evaluation as a simple metric of light availability in lakes. Light considerably influences macrophyte abundance, and all changes in water transparency induce variations in plant structure, in particular submerged vegetation, plant density and depth [28,[30][31][32][33]. An increase in the concentration of biogenic substances generally contributes to phytoplankton density and decreases water transparency, ultimately leading to the disappearance of plant species characteristic of water bodies that are less abundant in nutrients, and to excessive growth of filamentous green algae, species of the genus Potamogeton and helophytes [34][35][36][37].…”

“…An increase in the concentration of biogenic substances generally contributes to phytoplankton density and decreases water transparency, ultimately leading to the disappearance of plant species characteristic of water bodies that are less abundant in nutrients, and to excessive growth of filamentous green algae, species of the genus Potamogeton and helophytes [34][35][36][37]. In addition to colonization depth and the percentage cover of submerged macrophytes, Secchi disc visibility is also used in the multi-criteria method proposed by Sender et al [33] for the ecological assessment of lakes. For these reasons, the aim of this study was to show that it is possible to make a comparable assessment of the ecological status of lakes based on three variables (Z, C max and SD) and ESMI.…”

This article presents and tests a new method for the retrospective assessment of ecological status assessment of the lakes in accordance with the Ecological State Macophyte Index (ESMI), which is formally used in biological monitoring in Poland. The proposed method is based on three metrics, the Z colonization index, the average maximum depth of lake vegetation Cmax, and the Secchi disk depth. Mathematical functions of ecological class were developed on the basis of the mean values of these three indicators in summer for different ecological status classes in 88 stratified lakes in northern Poland and the Łęczyńsko-Włodawskie Lake District and five lakes in the catchment area of the Wel River (published data). The new metrics were validated on the basis of literature data—ESMI, Cmax, Z and SD values from 11 lakes near Olsztyn (Poland). The obtained results are similar to those calculated based on macrophyte field surveys and can be an alternative of the Ecological State Macophyte Index (ESMI), which is formally used in biological monitoring in Poland. The proposed method makes it possible to compare long-term changes in the ecological state of lakes, because it enables an analogous assessment on the basis of data calculated from historical bathymetric maps showing the distribution of hydro macrophytes (parameters Z and Cmax) as well as contemporary data, collected, among others, during hydroacoustic research.

This paper is a synthetic overview of some of the threats, risks, and integrated water management elements in freshwater ecosystems. The paper provides some discussion of human needs and water conservation issues related to freshwater systems: (1) introduction and background; (2) water basics and natural cycles; (3) freshwater roles in human cultures and civilizations; (4) water as a biosphere cornerstone; (5) climate as a hydrospheric ‘game changer’ from the perspective of freshwater; (6) human-induced stressors’ effects on freshwater ecosystem changes (pollution, habitat fragmentation, etc.); (7) freshwater ecosystems’ biological resources in the context of unsustainable exploitation/overexploitation; (8) invasive species, parasites, and diseases in freshwater systems; (9) freshwater ecosystems’ vegetation; (10) the relationship between human warfare and water. All of these issues and more create an extremely complex matrix of stressors that plays a driving role in changing freshwater ecosystems both qualitatively and quantitatively, as well as their capacity to offer sustainable products and services to human societies. Only internationally integrated policies, strategies, assessment, monitoring, management, protection, and conservation initiatives can diminish and hopefully stop the long-term deterioration of Earth’s freshwater resources and their associated secondary resources.

“…Water is a key to understand the cosmos, controls the Earth environment [1,2], and drive among other elements the biodiversity [3][4][5][6][7][8][9][10][11][12]. In this context, the importance of wetlands for aquatic, semi-aquatic, and terrestrial biotopes is essential, mostly when are impacted by humans, such cases being in all the Danube Basin countries [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30].…”

Throughout their history humans “tamed” not only the Danube River basin land, but also the river and its associated wetlands, drastically influencing their characteristic habitats, associations, communities, and species. One of these flagship endemic fish species in this respect is the European mudminnow (Umbra krameri Walbaum, 1792), influenced by Danube Basin geography, history, politics, and ecology. A study about this European community concern species in the context of long term human impact on its specific habitats, with potential synergic negative effects of climate change, was treated as highly needed, in an international researchers group initiative to support the efforts to provide hope for preserving this fish species and its ecosystems, and brought it back from the brink of extinction. All the characteristic inventoried wetlands which were or some of them still are natural, semi-natural, or accidental anthropogenic habitats, reveal an accentuated diminishing trend of this species areal continuity; fragmentation being the force which skewed it drastically untill now, and inducing diminishing the specific habitats quantitative and qualitative characteristics in the Danube Basin where these fish fight for survival. The main categories of human activities which impacted the climate changes in the context of this species’ habitats are: water regulation, pollution, dredging, draining, and introduction of non-native species. Overall, the diverse human impact in a climate changes in the context of this species’ habitats, Umbra krameri wetlands, creates serious perspectives on negatively influencing this at a very high scale and level. All the inventoried wetlands where Umbra krameri still survive can be considered an ecologically managed as a refuge and stepping stone wetlands, especially in the increasing climate change trend situation. Supplementary inventory studies in the field should be done for the identification of some may be unknown Umbra krameri habitats and populations.
