“…Another factor that limits the number of beetles is the depth. This suggestion is confirmed by the research completed by Brittain (1978), Pakulnicka, Górski & Bielecki (2015b) and Pakulnicka et al (2013Pakulnicka et al ( , 2015a. Among the lakes which we analysed, the ones that contained dark brown water with acidic reaction (Pakulnicka & Zawal 2018) there were no fish or amphibians, which are usually considered as one of the major factors limiting the presence of water beetles (Ericsson et al 1980;Solé & Rödder 2010).…”

“…zooplankton, smaller insects, like mayflies, or insect eggs (Frelik & Pakulnicka, 2015;Frelik, Koszałka & Pakulnicka, 2016;Perissinotto, Bird & Bilton, 2016). According to Scheffer & van Nes (2006), Pakulnicka et al (2013) and Scheffer et al (2015), what happens here is the evident division of functions, which relies on the principle of minimising similarity (being similar albeit different), as this minimizes competitiveness. As Scheffer et al (2015) maintain, these mechanisms ensure a certain measure of redundancy of similar species in the environment, which is essential for the functioning of ecosystems during unfavourable changes.…”

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.

“…However, for many others for which weak or average correlations are shown, these factors remain insignificant. This could point to the conclusion that the cooccurrence of certain species does indeed sometimes comply with niche theories according to which the most important are beneficial environmental conditions, while at other times species co-occurrence remains accidental, in line with the neutral theory (Pakulnicka et al, 2013).…”

-The goal of the study was to identify the beetle fauna of a small lowland river valley against its spatial arrangement and the directions of beetle migrations between habitats, as well as to determine which environmental factors affect the characteristics of water beetle populations in a river valley's lentic water bodies. The field studies were carried out in various types of water bodies. 112 species of beetles with various ecological characteristics were identified. It was demonstrated that the diversity of water bodies in the valley is conducive to high local species richness. At the same time, the observed high degree of faunistic individualism may be regarded as a sign of poor symmetry in the directions of fauna propagation, particularly that of stagnobionts. The authors argue that high individualism is the consequence of poor hydrological contact between the water bodies due to topography and rare instances of high tide in the river, which, in turn, is the reason for active overflights remaining the main mean of migration between those water bodies. The factors restricting migration of fauna between the water bodies include certain landscape characteristics of the catchment which form topographical obstacles, mainly numerous and dense forest areas. The character of fauna in the respective types of water bodies is affected also by internal environmental factors, particularly the degree to which they are overgrown with macrophytes, type of bottom, type of mineral and organic matter as well as physical parameters of water, such as saturation, pH, temperature and biological oxygen demand.Keywords: water beetles / river valley / migrations / hydrological system / ecological groups / landscape characteristics / environmental factors Résumé -Développement de la faune de coléoptères aquatiques (Coleoptera) dans les eaux d'une vallée -facteurs de l'habitat, paysage et géomorphologie. Le but de l'étude était d'identifier la faune de coléoptères d'une petite vallée d'une rivière de plaine en fonction de son paysage et des directions des migrations des coléoptères entre les habitats, ainsi que pour déterminer quels facteurs environnementaux influent sur les caractéristiques des populations de coléoptères aquatiques dans les plans d'eau d'une vallée. Les études sur le terrain ont été effectuées dans divers types de masses d'eau. 112 espèces de coléoptères avec diverses caractéristiques écologiques ont été identifiées. Il a été démontré que la diversité des masses d'eau dans la vallée est propice à la haute richesse des espèces locales. Dans le même temps, le degré élevé observé de l'hétérogénéité faunistique peut être considéré comme un signe de mauvaise symétrie dans les directions de propagation de la faune, en particulier celle des stagnobiontes. Les auteurs soutiennent que la forte hétérogénéité est la conséquence d'un mauvais contact hydrologique entre les masses d'eau en raison de la topographie et de rares inondations de la rivière, ce qui, à son tour, est la raison pour laquelle les survols

“…The quality of spring water, which reflects the water quality in the entire hydrological system, is regulated in part by the European Water Framework Directive (Williams and Williams, 1998;Glazier, 2009;Martin and Brunke, 2012), according to which one means of assessing the ecological status of aquatic environments is by monitoring the macroinvertebrates living in it. The importance of aquatic beetles has been emphasized in this context, as they are sensitive to environmental factors and generally react quickly to changes Foster and Eyre, 1992;Winfield Fairchild et al, 2000;Bosi, 2001;Menetrey et al, 2005;Pakulnicka, 2008;Giora et al, 2010;Pakulnicka and Nowakowski, 2012;Pakulnicka et al, 2013Pakulnicka et al, , 2015aPakulnicka et al, , 2015b. This is possible due to the considerable dispersal capacity of these insects (Bilton, 1994;Lundkvist et al, 2002), which allows them to move between water bodies that are often far apart, as pointed out by such authors as Biesiadka and Pakulnicka (2004), Pakulnicka and Nowakowski (2012), and Costea et al (2013) in regard to the hydrological system formed by aquatic environments in a river floodplain.…”

“…For biocenoses in springs the proximity of other aquatic environments is important as well (Pakulnicka, 1999). The role of biotic factors, including interspecies interactions, has been emphasized Lawton, 1990a, 1990b;Pakulnicka et al, 2013Pakulnicka et al, , 2015aFrelik, 2014;Frelik and Pakulnicka, 2015). Finally, in recent decades awareness is growing of the importance of factors shaping the landscape, such as geographical location and the type, structure, and use of the landscape, for aquatic environments and the macroinvertebrates inhabiting them (Castella et al, 1991;Delettre et al, 1992;Khmeleva et al, 1994;Richards and Host, 1994;Richards et al, 1996;Pakulnicka, 1999;Delettre and Morvan, 2000;Galic et al, 2013;Zawal et al, 2015aZawal et al, , 2015b.…”

-We identified the beetle fauna of springs of a small lowland river and attempted to determine the direction and magnitude of beetle migration between the springs and neighboring water bodies in the river valley, as well as the local environmental factors and landscape parameters that most influence the character of aquatic beetle assemblages in the springs. We studied springs of three limnological types, along the entire length of the river valley, and identified 42 beetle species. All types of springs were dominated by stagnobiontic species, which enter springs from other aquatic environments, mainly via dispersion by air. We also found a small proportion of crenophiles and a substantial proportion of rheophiles and tyrphophiles, which was linked to the close proximity of the river and dystrophic water bodies. The fauna of the springs was affected to a similar degree by local environmental factors and by landscape factors acting on a broader scale. This indicates the need for broader consideration of landscape factors, which are often neglected in ecological studies.Key-words: aquatic beetles / river valley / migration / synecological elements / landscape / environmental factors Résumé -Les coléoptères aquatiques (Coleoptera) des sources d'une petite rivière de plaine : facteurs d'habitat vs. facteurs de paysage. Nous avons identifié la faune des coléoptères des sources d'une petite rivière de plaine et tenté de déterminer la direction et l'ampleur de la migration des coléoptères entre les sources et les plans d'eau voisins dans la vallée, ainsi que les facteurs environnementaux locaux et les paramètres du paysage qui influencent le plus le caractère des assemblages de coléoptères aquatiques dans les sources. Nous avons étudié les sources de trois types limnologiques, sur toute la longueur de la vallée de la rivière, et identifié 42 espèces de coléoptères. Tous les types de sources ont été dominés par des espèces stagnobiontes qui viennent d'autres milieux aquatiques, principalement par dispersion par voie aérienne. Nous avons également constaté une faible proportion de crénophiles et une proportion importante de rhéophiles et tyrphophiles, qui a été reliée à la proximité de plans d'eau et rivières dystrophiques. La faune des sources a été affectée à un degré similaire par des facteurs environnementaux locaux et par des facteurs paysagers agissant sur une plus grande échelle. Cela souligne la nécessité d'un examen plus large des facteurs de paysage, qui sont souvent négligés dans les études écologiques.
