“…or Acorus sp. Many hydrobiologists emphasize the important role of the littoral zone in the secondary production of lakes and as a zone having the highest species richness and density of macroinvertebrates ( Cremona, Planas & Lucotte, 2008 ; Timm & Möls, 2012 ; Mieczan et al, 2014 ; Płaska & Mieczan, 2018 ). The littoral zone is also considered to be the most sensitive part of a lake, and its character provides evidence on the ecological condition of the whole lake ( Czachorowski, 1998 ; Šiling & Urbanič, 2016 ).…”

“…In our study we looked at water beetles because they are particularly numerous organisms in the littoral zone as well as being very sensitive and responsive to any unfavourable changes in the environment ( Eyre, Foster & Foster, 1992 ; Foster & Eyre, 1992 ; Corbet et al, 1980 ; Winfield Fairchild, Faulds & Matta, 2000 ; Bosi, 2001 ; Menetrey et al, 2005 ; McFarland, Carse & Sandin, 2009 ; Gioria, Bacaro & Feehan, 2010a ; Gioria et al, 2010b ; Yee, 2014 ). Furthermore, many species are predators, which defines their important role as organisms regulating the abundance and species richness of concurrent taxa ( Yee, 2014 ; Frelik & Pakulnicka, 2015 ; Frelik & Pakulnicka, 2015 ; Perissinotto, Bird & Bilton, 2016 ; Miller & Bergsten, 2016 ; Płaska & Mieczan, 2018 ). Water beetles penetrate both the ground and the water column, so according to McAbendroth et al (2005) , their ecological niche is three-dimensional.…”

Effect of changes in the fractal structure of a littoral zone in the course of lake succession on the abundance, body size sequence and biomass of beetles

Dystrophic lakes undergo natural disharmonic succession, in the course of which an increasingly complex and diverse, mosaic-like pattern of habitats evolves. In the final seral stage, the most important role is played by a spreading Sphagnum mat, which gradually reduces the lake’s open water surface area. Long-term transformations in the primary structure of lakes cause changes in the structure of lake-dwelling fauna assemblages. Knowledge of the succession mechanisms in lake fauna is essential for proper lake management. The use of fractal concepts helps to explain the character of fauna in relation to other aspects of the changing complexity of habitats. Our 12-year-long study into the succession of water beetles has covered habitats of 40 selected lakes which are diverse in terms of the fractal dimension. The taxonomic diversity and density of lake beetles increase parallel to an increase in the fractal dimension. An in-depth analysis of the fractal structure proved to be helpful in explaining the directional changes in fauna induced by the natural succession of lakes. Negative correlations appear between the body size and abundance. An increase in the density of beetles within the higher dimension fractals is counterbalanced by a change in the size of individual organisms. As a result, the biomass is constant, regardless of the fractal dimension.

“…Moreover, the density of plants also affects the predation capability of fish and invertebrate predators [30,31]. Despite the fact that the denser the macrophyte coverage, the better the refuge they offer, juvenile fish and invertebrates tend to suppress zooplankton communities in littoral zones/environments [32][33][34]. Furthermore, the structure of littoral zones affects the species distribution of littoral cladocerans, since cladocerans effectively share resources, allowing the co-existence of a high number of species [35][36][37].…”

The body size of aquatic invertebrates is, to a great extent, dependent on ambient temperature, but size distributions are also determined by other factors like food supply and predation. The effect of temperature on organisms is formulated in the temperature–size hypothesis, which predicts a smaller body size with increasing temperature. In this study, the effect of temperature on the subfossil remains of three littoral Cladocera (Alona affnis, A. quadrangularis, and Chydorus cf. sphaericus) was investigated. Exoskeletal remains of these species can be found in large numbers in lacustrine sediments and over a wide north–south range in Europe. The total length of both headshield and postabdomen for A. affinis and A. quadrangularis and carapace length for C. cf. sphaericus were measured to observe their response to changes in latitude and temperature. A different response to ambient temperature in the growth of body parts was observed. The size of the headshields of both Alona species and of the carapace of Chydorus was significantly larger in colder regions as opposed to warm ones. It turned out that the postabdomen was not a good predictor of ambient temperature. While the sizes of all remains increased with latitude, the sizes of the Alona remains was smaller in the mountain lakes of the Southern Carpathians than in other cold lakes, in this case in Finland, a fact indicative of the importance of other factors on size distribution. This study demonstrates that a morphological response to climate is present in littoral cladocerans, and, therefore, changes in the length of headshield and carapace may be used as a proxy for climate changes in paleolimnological records.

“…Also, the macrophytes may have direct benefits of food or indirect ones by providing a large surface area on which epiphytic algae can grow and, manipulate organic matter can settle. Also, Interactions within the food chain are essential to ecosystem ecology (Płaska and Mieczan, 2018). Macrophytes also provide shelter from water turbulence and predators, for many species (Petr, 1968 ;Cattaneo, 1983).…”

The present work aims to study the relationship between some physico-chemical parameters and both planktonic and epiphytic microinvertebrates associated with the floating plant Eichhornia crassipes in River Nile at Qanater region. Water samples, planktonic and epiphytic microinvertebrates were collected seasonally from eight sites in the investigated region. The results indicated that the maximum occurrence of planktonic invertebrates (810 org./L) was recorded during Winter. Rotifera formed the highest percentage of zooplankton (96.77 %), followed by Copepoda (1.88 %) and Cladocera (1.10 %). Meroplankton and Protozoa formed the lowest dominant groups. Thirty seven planktonic species were recorded belonging to Rotifera (30 species), Cladocera (2 species), Copepoda (1 species), Protozoa (2 species) and Meroplankton (2 species). On the other hand, the maximum occurrence of epiphytic invertebrates (1612100 org./m 2 plant) was recorded during spring. Forty five species were recorded belonging to Rotifera (27 species), Protozoa (5 species), Cladocera (9 species), Copepoda (2 species) and Oligochaeta (2 species).The epiphytic microinvertebrates associated with the floating plant Eichhornia crassipes in River Nile at Qanater region recorded the highest number of species and groups than planktonic invertebrates. This indicates that the aquatic plant Eichhornia crassipes habitats are more diverse and have high species richness. The principal component analysis (PCA) was conducted between physico-chemical parameters and planktonic and microinvertebrates.
