“…A variety of mechanistic explanations for increased biodiversity with increasing stream size have been proposed. Among these explanations are increased habitat size or area [13,[27][28][29], increasing habitat complexity [30][31][32][33], habitat stability [14,34], effects of temperature or temperature variability [35][36][37], effects of flow variability [38] and an increasingly complex trophic base as nutrients and particulates from allochthonous decomposition are transported downstream to mix with autochtonous production [22]. It is also expected that many of these mechanisms may function interactively and that different mechanisms will drive these patterns across different taxonomic and functional groups of organisms, and that mechanism will vary across spatial scale [39][40][41].…”

Does Stream Size Really Explain Biodiversity Patterns in Lotic Systems? A Call for Mechanistic Explanations

Understanding drivers of biodiversity is a long-standing goal of basic and applied ecological research. In riverine systems, there remains a critical need to identify these drivers as efforts to manage and protect rivers grow increasingly desperate in the face of global change. We explored one commonly cited potential driver of riverine biodiversity, stream size (e.g., stream order, watershed area, width), using a systematic literature review paired with an analysis of broad-scale macroinvertebrate and fish communities. Of the 165 papers reviewed, we found mostly positive, but no universal, relationship between biodiversity and stream size despite inconsistent use of over 30 measures of stream size. One-third of studies failed to report explanatory mechanisms driving biodiversity-stream size relationships. Across over 4000 macroinvertebrate and fish samples from 1st-8th order streams in the contiguous USA, our analysis showed biodiversity (Shannon diversity, functional diversity, beta diversity) generally increased with measures of stream size. However, because of inconsistent and generally weak relationships between biodiversity and stream size across organismal groups, we emphasize the need to look beyond simple physical stream size measures to understand and predict riverine biodiversity, and strongly suggest that studies search for more mechanistic explanations of biodiversity patterns in lotic systems.

“…EC and temperature have been found most important to the development of caddisfly larvae in different types of waters (e.g. Kalaninová et al, 2014), including manmade reservoirs (Prommi and Thani, 2015;Buczyńska et al, 2016). ORP, on the other hand, is rarely mentioned in the literature.…”

Shallow and vegetation-rich storage reservoirs can be a very important element of a hydrological network supporting specific fauna. However, their ecological potential for many insect groups is often neglected in hydrobiological studies in contrast to lakes. Therefore, caddisfly fauna was studied at different levels of its organization as well as environmental drivers of the species' distribution across three reservoirs (SE Poland). The species' composition and assemblages distinguishingly showed close relationships with the caddisfly fauna of meso- and eutrophic lakes. Quantitative naturalness index (Wns) of caddisfly fauna in all reservoirs was higher in comparison to this value obtained for regional lakes. Oxygen reduction potential, temperature, electrical conductivity (physical and chemical variables of water), shading, elodeids (structural variables of reservoirs) and the average distance to the nearest water bodies (landscape variables in buffer zones of reservoirs) were all significant for caddisflies in CCA models. Analysis of functional groups revealed two characteristic features of these habitats: the lack of rheophiles and an evenly balanced trophic structure. Shallow reservoirs, despite their origin and human intervention, can provide important secondary habitats for specific invertebrate fauna. Practical guidelines are also given concerning management practices favourable to aquatic biota.

“…The analysis of the influence of selected physical and chemical water parameters on macroinvertebrate communities includes different levels of organism identification [21][22][23][24]. In the present study, as well as in many biotic indices used for water quality assessment (for example RIVPACS [25], BMWP [26], MMI_PL [27]), the macrofauna is identified with an accuracy to the family level.…”

Impact of heated waters on water quality and macroinvertebrate community in the Narew River (Poland)

The effect of heated waters from coal-burning power stations on the water parameters and the occurrence of macroinvertebrates depends on the individual characteristics of the river to which the heated waters are discharged. The objective of the study was to assess the impact of heated water from the Ostrołęka Power Station on selected water properties and the macroinvertebrate community in the Narew River. Samples were collected in years: 2013-2016 along two river stretches: upstream and downstream of the canal. The water temperature was higher and the oxygen concentrations were lower at the downstream sites compared to the upstream sites of the canal. The values of conductivity, concentrations of nitrates, phosphates, chlorides and calcium were similar at the sampling sites. A total of 33 families of macrozoobenthos were found. The numbers of families were positively correlated with the temperature and conductivity and negatively correlated with oxygen. The heated waters were found to have no effect on the Shannon-Wiener diversity index. The inflow of heated waters increased the percentage of Gammaridae, represented by species Dikerogammarus haemobaphes (Eichwald, 1841) and decreased the percentage of Chironomidae. The presence of the thermophilous bivalve Sinanodonta woodiana (Lea, 1934) was noted downstream of the canal.
