“…Balloch et al ., ; Armitage et al ., ). In our study, we did not recommend to calculate an average value because a sampling approach was standardized by area (Urbanič et al ., ). In support, we observed a good relationship between the LM pressure (LMI) and the number of families (Figure ), which finally takes the richness moment in the LFI into account.…”

“…Sampling sites were selected in the middle of each 20 m wide lakeshore modification assessment section used in the assessment of the stressor gradient. A proportional stratified sampling approach was used and the sampling regime followed the littoral microhabitat type sampling protocol (Urbani c et al, 2012). In the littoral microhabitat type, the strata are defined as a combination of a depth class and a substrate category (inorganic and organic) proportionate to their coverage in the sampling site.…”

“…Aroviita and Hämäläinen, 2007;Brauns et al, 2007a;White et al, 2010). Studies investigating hydromorphological pressures that affect littoral benthic invertebrates, however, have focused on the impact of water level fluctuations, whereas the impact of morphological lakeshore modifications has rarely been tested (see Bänzinger, 1995;Brauns et al, 2007b;McGoff and Sandin, 2012;Porst et al, 2012;Urbani c et al, 2012). The need to include this pressure is essential given that lakeshore deterioration is a major threat to the ecological integrity of lakes worldwide (Ostendorp et al, 1995;Engel and Pederson, 1998;Elias and Meyer, 2003).…”

Lakeshore deterioration is a major threat to the ecological integrity of lakes worldwide. In this study, the relationship between littoral benthic invertebrates and the Lakeshore Modification Index (LMI) was examined. The influence of the taxonomic resolution on littoral benthic invertebrate community response to LMI was assessed using the results of the canonical correspondence analysis and the relationship between the taxa richness, Shannon–Wiener diversity index and the LMI. Benthic invertebrates were sampled in summer between 2006 and 2011 in two natural and two artificial Alpine lakes using a littoral microhabitat type sampling scheme. Ordination analyses show a similar explanation power when the lowest available taxonomic level was used in comparison with the family level. Taxa richness and the Shannon–Wiener diversity index indicate that lakeshore modifications impair littoral biological conditions with a loss of richness and diversity independently of lake type and used taxonomic level. For 64 families, a lakeshore modification indicative value between one and nine were set on the basis of distribution among five lakeshore modification classes. A Littoral Fauna Index (LFI) was then derived by summation of the lakeshore modification indicative values recorded at each site. A validation dataset from natural and artificial lakes confirmed the good relationships between LMI and LFI but revealed some differences in the relationships. The results show that the impacts of lakeshore modifications can be assessed using littoral benthic invertebrate assemblages with a family‐level‐based LFI, which makes this method cost effective and appropriate for routine monitoring.

“…Many of the hydromorphological characteristics that influence macrophytes in lakes will, by extension, affect other organisms, such as invertebrates. Yet, there are relatively few studies that directly link macroinvertebrate communities in lakes to hydromorphological factors (but see McGoff et al, ; Peterlin & Urbanič, ; Smith, Maitland, & Pennock, ; Urbanič, ; Urbanič, Petkovska, & Pavlin, ).…”

Methods for assessing the hydrology and morphology of lakes (‘hydromorphology’) are needed for reporting under national and international legislation, as well as to assist in lake management and restoration. Despite this, no consistent approaches have been developed around Europe for monitoring lake hydromorphology. To address this need, representatives from 12 countries met at a series of workshops to develop two protocols for monitoring, published under the auspices of the European Committee for Standardization (CEN). The first standard (EN 16039) describes six categories for assessing lake hydromorphology: hydraulics, morphometry, bedforms/landforms and substrate, connectivity and continuity, and land cover. The second standard (EN 16870) sets out a scoring system for assessing the degree of modification of lake hydromorphology, which was designed, tested and refined using data from 127 lakes in seven European countries. The CEN standards focus on four lake zones—riparian, shore, littoral, and open water—but recognize the importance of considering lakes within their wider catchment context. The field techniques described are based largely on Lake Habitat Survey but also rely on existing databases, maps and remote‐sensing data. These standards are aimed at scientists, conservation bodies and environmental regulators, and are relevant not only for monitoring lakes under the Water Framework Directive, but also for contributing to programmes of lake conservation. For example, in the UK, parts of the CEN standards have been incorporated within the methods used for monitoring and reporting on the condition of Special Areas of Conservation (under the Habitats Directive) and Sites of Special Scientific Interest under national legislation. It is hoped that this pan‐European approach will improve the ability to compare data across many countries, and ultimately ensure that the results of monitoring are translated into measures for improving the hydromorphological condition of lakes and the biological communities they contain.
