“…(). The LHS features 'Lakewards extension of macrophytes', ‘Macrophyte PVI', ‘Diversity of macrophyte types', ‘Diversity of littoral features', 'Vegetation structural complexity' and ‘Diversity and extent of natural land‐cover types' identified as relevant for macroinvertebrate diversity and community structure (Jurca et al ., ; McGoff et al ., ) were also included as components of the stressor index developed in this study. More specifically, ‘Vegetation structural complexity' and ‘Diversity of macrophyte types' in Ireland/Great Britain and ‘Macrophyte PVI' in central Italy/northern Italy (McGoff et al ., ) correspond in this study to the stressor index components ‘Sum of vegetation cover types', ‘Sum of macrophyte types' and ‘Total PVI' in the respective geographical regions.…”

ABSTRACT1. Morphological degradation constitutes one of the most severe threats to the ecological integrity of lakes. The development of biotic assessment methods for human lake shore alterations using littoral macroinvertebrates requires quantification of the degree of degradation by a stressor index and is complicated through simultaneous physical pressures that alter natural habitat structure.2. The Lake Habitat Survey (LHS) method and macroinvertebrate sampling were used to produce a pan-European dataset of morphological lake shore degradation and macroinvertebrate densities covering 51 lakes in seven countries and across four geographical regions -northern, western, southern and central Europe.3. Lake Habitat Survey parameters that differed significantly among three categories of morphological pressure were combined to develop the stressor index components 'Number of habitats', 'Habitat diversity', 'Total percentage volume inhabited by macrophytes', 'Sum of macrophyte types', 'Sum of vegetation cover types', 'Sum of coarse woody debris/roots/overhanging vegetation', 'Pressure index' (number of human disturbance sources) and 'Natural/artificial dominant land cover type '. 4. Stressor index components were tested for cross-correlations and for differences among pressure levels. The final composition of the stressor index was optimized for the four studied geographical regions in Europe. The resulting stressor index correlated more strongly with macroinvertebrate metrics than simpler site-specific LHS parameters or the HabQA index developed previously in one lake in north-western Europe.5. The stressor index developed provides deeper insight into the morphological pressures that affect littoral invertebrate communities. The results also support the use of LHS to quantify morphological stressors at sampling site level, which can ease developing other multimetric bioassessment methods.6. The stressor index offers the possibility for wide and regional specific application to assess hydromorphological pressures on lakes to assist conservation planning and management and further global efforts to develop and test biotic assessment methods for lakes.

“…The LHQA-littoral score accounts for several features of the littoral zone including the diversity of sediment types, the diversity and extent of macrophyte cover, and the presence of shelters against fish predation (Rowan et al 2006). Thus, habitat complexity seems to be a prominent factor structuring invertebrate communities (Cheruvelil et al 2002, McGoff and Irvine 2009, Jurca et al 2012.…”

Relative impacts of morphological alteration to shorelines and eutrophication on littoral macroinvertebrates in Mediterranean lakes

Development of effective methods for assessing the ecological status of lakes based on littoral benthic fauna has been hampered by the lack of quantitative data on the relative impacts of key pressures on the benthic community. We used variance partitioning at 126 sites belonging to 14 natural Mediterranean lakes to analyze the pure and shared effects of eutrophication, morphological alterations, microhabitat type, lake morphometry and geographic position on the littoral macroinvertebrate community. The spatial arrangement of the sampling sites was responsible for 9.1% of the total variance in littoral benthic community composition, lake morphometry accounted for 4.3% of variation, and microhabitat type accounted for 3.9%. Communities appeared to be affected primarily by morphological alterations to lake shorelines, and their impact was 2.5 times as important as that of eutrophication. The structure of littoral benthic communities was governed by processes acting at several spatial scales from region to lake scale. Thus, several pressures and the various spatial scales at which these act should be taken into account when implementing methods of assessing lake ecological condition based on littoral benthic invertebrates. Region-specific methods for subalpine and volcanic lakes might enhance the validity of assessment of results of morphological alterations and improve management of those water resources.

“…The high physical complexity and habitat diversity in the littoral zone allows macrozoobenthos taxa to use manifold ecological niches, resulting in the formation of complex food webs (Brauns et al, 2011;Strayer and Findlay, 2010;Taniguchi and Tokeshi, 2004). Littoral invertebrates have shown to be influenced by eutrophication (Donohue et al, 2009;Jurca et al, 2012;Tolonen et al, 2001), as well as by hydromorphological degradation, e.g. through urban development, bank protection measures such as stone walls and rip-rap (Brauns et al, 2007a,b;Porst et al, 2012).…”
