“…The building activity of beavers also causes changes in water environment, especially in small rivers and small streams, although this is a natural phenomenon. The decreased current velocity and increased water retention time in beaver ponds or small reservoirs favour the development of limnetic organisms among the microflora, macrophytes, micro‐ and macroinvertebrates, and vertebrates, especially the ichthyofauna (Swales & Levings, ; Otahelová & Valachovič, ; Cumming, ; Lindstrom & Hubert, ; Sharma, Sharma, Borgstrom, & Bryceson, ; Zhou, Tang, Wu, Fu, & Cai, ; Arndt & Domdei, ; Kemp, Worthington, Langford, Tree, & Gaywood, ; Czerniawski & Domagała, ; Bylak, Kukuła, & Mitka, ; Czerniawski, Sługocki, & Kowalska‐Góralska, ). The authors report that a rapid increase of organic and inorganic matter, atypical for running water conditions, occurs in these water basins that disturb the natural order of the stream.…”

“…As in the case of large rivers, changes in the zooplankton communities in streams are related to physical and chemical changes caused by the appearance of beaver‐ and human‐made impoundments. The new stream conditions favour the development of the very same zooplankton species present in lakes (Czerniawski & Domagała, ; Zhou et al, ). As mentioned above, the zooplankton are typical lentic animals that cannot develop in running waters with high current velocities (Ejsmont‐Karabin & Kruk, ).…”

“…As mentioned above, the zooplankton are typical lentic animals that cannot develop in running waters with high current velocities (Ejsmont‐Karabin & Kruk, ). However, due to altered hydrology in beaver ponds and in reservoirs, zooplankton can exist and maintain their populations (Zhou et al, 2008; Błędzki, Bubier, Moulton, & Kyker‐Snowman, ; Czerniawski & Domagała, ). This is mainly affected by the low values of current velocity.…”

“…These main variables determine the presence of zooplankton in rivers, as they offer better conditions for reproduction of numerous zooplankton species (Basu & Pick, ; Lair, ; Vranovsky, ). However, the effect of beaver ponds and small reservoirs on the zooplankton communities has been described in only a few papers (Krylov, ; Krylov, ; Zhou et al, 2008; Błędzki et al, ; Czerniawski & Domagała, ). The authors revealed that beaver impoundments and small human‐made impoundments cause significant changes in the zooplankton richness and abundance in the stream, while simultaneously changing the amount of organic matter in the downstream.…”

“…In the summer, there is a relatively high abundance of planktonic rotifers or minor crustaceans in small reservoirs, of more than 200 ind. L −1 , and that value is greater by 80% compared with the upstream (Zhou et al, 2008; Czerniawski & Domagała, ). Therefore, the zooplankton are indicators that react rapidly to hydrological changes in lotic waters.…”

Small human‐made dams and beaver ponds cause significant changes in the environment of small streams. The decreased current velocity and increased water retention time in these impoundments favour the development of limnetic organisms, for example, zooplankton. However, small human‐made reservoirs are regulated, deep and narrow, whereas beavers create relatively large impoundments with numerous shallow patches and their impact on the stream zooplankton communities can be different. We compared the effect of beaver ponds and small reservoirs on the zooplankton communities in streams. Three sample collection sites were established in each stream. Site 1 was approximately 100 m upstream of the water impoundment formed by the dam. Site 2 was at the dam impoundment of the stream water. Site 3 was approximately 300 m below the dam. Beaver ponds have a larger impact on the zooplankton richness and the abundance changes compared with seminatural reservoirs not maintained by people, and a much greater impact than reservoirs regularly cleaned and regulated. Beaver ponds create heterogeneous environment that favour the occurrence of a greater number of zooplankton species compared with small reservoirs. Moreover, the increase in organic matter in the downstream areas could lead to trophic changes in the stream.

This study aimed to evaluate the zooplankton structures and environmental conditions in the interface reservoir‐downstream river and tributaries. Zooplankton structure and environmental variables were analyzed in the lacustrine zone of Itaipu Reservoir and downstream this dam at Paraná River and in two lateral tributaries. A total of nine sites were sampled in July 2009 and January 2010 (winter/dry vs. summer/wet). In the free‐flowing section downstream of the Itaipu Reservoir (Paraná River), the physical–chemical influence of the dammed water can persist for approximately 15 km in the dry period and 30 km in the rainy period. The lateral tributaries (Iguaçu and Monday Rivers) introduce sediments (particulate organic and inorganic matter), nutrients and potamoplankton biota that contribute to fluvial restoration, particularly in the dry period when the main river flow is low. The zooplankton community structure and composition varied over space (longitudinal) and time. Rotifers dominated in the lateral tributaries, whereas microcrustaceans from the reservoir were abundant in the Paraná River. The density of zooplankton downstream of the reservoir decreased, with the highest reduction occurring in the first 5 km downstream of the dam, however, the species composition persisted in the all free‐flowing section downstream studied. Associations were found among zooplankton abundance and environmental variables, mainly the current velocity and water discharge; zooplankton groups had different responses to these variables. Differences in the zooplankton ecological structure along a stretch of the Paraná River clearly indicate the effects of damming and tributaries.

The construction of small hydroelectric plants (SHPs) has increased greatly worldwide, and the impacts of these impoundments can cause changes in the aquatic biota. Here, we investigated the ecological attributes (abundance, richness, and species diversity) of three communities (phytoplankton, invertebrates in the water column, and benthos) and the functional groups of phytoplankton, before and after the construction of five SHPs in an Amazonian river. The communities were sampled at two sites, one upstream and another downstream of each dam or construction site, before the dam closure. The dam did not change the limnological factors, and the acid waters and low electrical conductivity, typical of “cerrado” rivers, were characteristic of both the pre‐ and post‐dam phases. For aquatic communities, the phytoplankton abundance increased and the diversity of groups decreased in the post‐dam phase. Regarding the morphology‐based functional groups (MBFG), there was an increase in groups I (small algae with a high surface/volume ratio) and V (phytoflagellates), with a reduction in groups VI (diatoms) and VII (large mucilaginous colonies) in the post‐dam phase. The relative abundance of zooplankton species increased in the post‐dam phase, and the opposite was observed for the benthic community, with reductions in abundance, richness, and group diversity in the post‐dam phase. The structure of the three communities differed between the pre‐ and post‐dam phases, but no difference in communities' similarity was observed between the upstream and downstream sites in both phases. The results show that the change in hydrodynamics, from lotic to semi‐lentic, in the reservoirs of the SHPs, was the main driving force for the alterations in the three communities. For phytoplankton, SHPs are favorable in the sense of decreasing the incidence of algal blooms, particularly of cyanobacteria.
