Since 2000, after the Water Framework Directive came into force, aquatic ecosystems' bioassessment has acquired immense practical importance for water management. Currently, due to extensive scientific research and monitoring, we have gathered comprehensive hydrobiological databases. The amount of available data increases with each subsequent year...
In this study, we aimed to identify the macrophyte pattern and diversity under exposure to substantial hydromorphological degradation in rivers, taking into account the water quality factor. The study was based on 190 small and medium lowland rivers in Poland that had experienced channel alterations. The number of taxa identified (153 species) was...
Ranunculus species grouped in the section Batrachium (water crowfoots) indicate the most valuable fluvial habitat in Europe under the EU Habitats Directive, and recognition of their environmental preferences plays a crucial role in efficient conservation. Moreover, water crowfoots are used in various monitoring systems throughout Europe. The aim of...
Major threats of freshwater systems are river damming and habitat degradation, further amplified by climate change, another major driver of biodiversity loss. This study aims to understand the effects of climate change, and its repercussions on hydropower production, on the instream biota of a regulated river. Particularly, it aims to ascertain how...
Multivariate polynomial regression (MPR) models were developed for five macrophyte indices. MPR models are able to capture complex interactions in the data while being tractable and transparent for further analysis. The performance of the MPR modeling approach was compared to previous work using artificial neural networks. The data were obtained fr...
This work assesses the effects of river regulation on the diversity of different instream and riparian biological communities along a relieve gradient of disturbance in regulated rivers. Two case studies in Portugal were used, with different river regulation typology (downstream of run-of-river and reservoir dams), where regulated and free-flowing...
The method based on original metric called Hydromorphological Index for Rivers (HIR) was developed in 2017 for the purpose of the monitoring of the hydromorphological status of flowing waters in Poland. It fulfils the re-quirements of the EU Water Framework Directive (WFD). It allows the assessment of both lowland rivers as well as mid-altitude and...
The method based on original metric called Hydromorphological Index for Rivers (HIR) was developed in 2017 for the purpose of the monitoring of the hydromorphological status of flowing waters in Poland. It fulfils requirements of the EU Water Framework Directive (WFD). It allows assessment of both lowland rivers as well as mid-altitude and highland...
The Macrophyte Index for Rivers (MIR) was developed in 2007, and it was one of the first biological methods developed in Poland under the requirements of the Water Framework Directive to assess the ecological status of running waters. It is based on the quantitative and qualitative evaluation of 153 indicator taxa. The aim of this study was to eval...
Change in plants as bicarbonate rises
Freshwater plants can be broadly divided into two major categories according to their photosynthetic traits: Some use carbon dioxide as their carbon source, whereas others use bicarbonate. Iversen et al. found that the relative concentrations of these two inorganic carbon forms in water determine the functional...
To test the hitherto generally-accepted hypothesis that most aquatic macrophytes have broad world distributions, we
investigated the global distribution, diversity and endemism patterns of 3457 macrophyte species that occur in
permanent, temporary or ephemeral inland freshwater and brackish waterbodies worldwide. At a resolution of 10x10°
latitude...
The aim of the study was to develop predictive models of the ecological status of rivers by using artificial neural networks. The relationships between five macrophyte indices and the combined impact of water pollution as well as hydromorphological degradation were examined. The dataset consisted of hydromorphologically modified rivers representing...
The proposed method is based on original metric called Hydromorphological Index for Rivers (HIR) and can be used in the hydromorphological assessment of all types of flowing waters in Poland. It allows assessment of both lowland rivers as well as mid-altitude and highland streams. The proposed system can be used to assess the natural and heavily mo...
Methodology of Hydromorphological Assessment in Poland
Biomonitoring methods based on macrophytes have been used mandatorily in the assessment of freshwaters since the implementation of the Water Framework Directive (WFD). The Macrophyte Index for Rivers (MIR) was developed in Poland for the monitoring of running waters under the WFD requirements. This index shows the degree of river degradation under...

It allows assessment of both lowland rivers as well as mid-altitude and highland streams. The proposed system can be used to assess the natural and heavily mo...
The variation of a number of parameters characterizing aquatic plant assemblages in rivers across a wide trophic gradient was investigated to evaluate their usefulness for a Polish national river monitoring system. Analyses were conducted at 100 sites included in the national river monitoring system, representing a uniform river type, i.e., small-...
Monitoring of water ecosystems in Kazakhstan is based generally on chemical indicators. Biological indicators, such as macroinvertebrates and a phytoplankton are rarely used. Sometimes some macrophyte species of are used for the assessment of water quality. The aim of the study was to analyse the possibilities of the introduction of the Polish moni...
The study focused on modelling of macropyte indices against physico-chemical parameters of waters by artificial neural networks. Several macrophyte diversity indices were analysed (species richness—N, the Shannon index—H′, the Simpson index—D, and the Pielou index—J) as well as the ecological status index (the Macrophyte Index for Rivers—MIR). The...
The aim of the study was to demonstrate the relationship between macroinvertebrate assemblages and aquatic vegetation interacting with chemical and geomorphological factors. The survey was carried out in the catchment of a lowland river in Poland in the year 2009. Macroinvertebrate samples were collected on 19 river sites during two campaigns (spri...
Summary. The nature of a river bed, in addition to water chemical parameters, is one of the main factors influencing the occurrence and development of aquatic flora and fauna. Heterogeneous in terms of the occurrence of natural morphological forms and elements, a habitat shows a high potential as a place where different organisms can settle in. Thi...

The RIVEAL project (PTDC/CTA-AMB/29790/2017) aims to map and quantify key ecosystem services (ES) of riparian forests and predict the balance of ES under diverse climatic, land use and water management scenarios in the Portuguese fluvial landscapes.

Testing various statistical methods on river monitoring big data;
Synthesize the effect of individual habitat characteristics, including natural and anthropogenic factors, on aquatic biota;
Determination which factors have a major, minor or no effect on organism (presented as ecological status metrics, diversity indices, species composition) under the simultaneous influence of other stressors.
The research aim of the project is to examine the response of aquatic plants to stress related to the anthropogenic transformation of riverbeds. The second objective of this project is to develop analytical methods for bioindication studies of aquatic ecosystems through the use of advanced data analysis programs such as artificial neural networks.
