“…As in our study, they found that reservoir fishes were a subset of those found in rivers and that Jaccard's indices of similarity between streams and reservoirs was 0.38, which was comparable to values we found across the three basins (0.27-0.30). We agree with Irz et al (2006) that reservoir and stream faunas are to some extent dependent on each other and should be considered in catchment-scale management efforts. This is particularly relevant to managing the spread of invasive species, as many species are introduced to reservoirs and subsequently spread to streams (Havel et al, 2005;Johnson, Olden & Vander Zanden, 2008).…”

“…Although our analyses focused on three drainage basins in the Great Plains, convergence of littoral zone fish communities is probably a general pattern in freshwater river systems. For example, Irz et al (2006) also documented local and regional controls of reservoir fish faunas in France. As in our study, they found that reservoir fishes were a subset of those found in rivers and that Jaccard's indices of similarity between streams and reservoirs was 0.38, which was comparable to values we found across the three basins (0.27-0.30).…”

“…Irz et al, 2002), as new impoundments undergo a predictable increase in productivity followed by a gradual decline as nutrients from inundated vegetation and soils are depleted (Kimmel & Groeger, 1986). Irz, Argillier & Oberdorff (2004) found that native fish diversity in reservoirs in France was positively correlated with regional richness, but in a complementary study (Irz et al, 2006) the same authors found no difference in mean local species richness among lakes, reservoirs and rivers. Han et al (2008) also found a positive association between total species richness and exotic species richness in Japanese reservoirs, and that more exotic species also tended to occur near developed areas, suggesting human transport was an important factor determining the presence of exotic fishes.…”

Convergence of fish communities from the littoral zone of reservoirs

1. Understanding factors that regulate the assembly of communities is a main focus of ecology. Human-engineered habitats, such as reservoirs, may provide insight into these assembly processes because they represent novel habitats that are subjected to colonization by fishes from the surrounding river basin or transported by humans. By contrasting community similarity within and among reservoirs from different drainage basins to nearby stream communities, we can test the relative constraints of reservoir habitats and regional species pools in determining species composition of reservoirs. 2. We used a large spatial database that included intensive collections from 143 stream and 28 reservoir sites within three major river basins in the Great Plains, U.S.A., to compare patterns of species diversity and community structure between streams and reservoirs and to characterize variation in fish community structure within and among major drainage basins. We expected reservoir fish faunas to reflect the regional species pool, but would be more homogeneous that stream communities because similar species are stocked and thrive in reservoirs (e.g. planktivores and piscivores), and they lack obligate stream organisms that are not shared among regional species pools. 3. We found that fish communities from reservoirs were a subset of fishes collected from streams and dominant taxa had ecological traits that would be favoured in lentic environments. Although there were regional differences in reservoir fish communities, species richness, patterns of rank abundance and community structure in reservoir communities were more homogonous across three major drainage basins than for stream communities. 4. The general pattern of convergence of reservoir fish community structure suggests their assembly is constrained by local factors such as habitat and biotic interactions, and facilitated by the introduction of species among basins. Because there is a reciprocal transfer of biota between reservoirs and streams, understanding factors structuring both habitats is necessary to evaluate the long-term dynamics of impounded river networks.

“…Such opportunities are most frequently reported for populations of generalist or non-native lacustrine species (e.g., Kruk and Penczak 2003) or the establishment of recreationally important species through stocking (e.g., Cowx 1998;Cowx et al 1998;Hunt et al 2010). Nevertheless, the impounded water of reservoirs can also provide benefits to remnant riverine fish species (Irz et al 2006;Ebner et al 2011;Lintermans 2012). Examples include paddlefish (Polyodon spathula) in the United States (Paukert and Fisher 2001;Scarnecchia et al 2009) and golden galaxias (Galaxias auratus) (Hardie et al 2007(Hardie et al , 2013 and Macquarie perch (Macquaria australasica) (Cadwallader 1981;Appleford et al 1998) in Australia.…”

Rapid increases in native riverine fish populations associated with trophic upsurge immediately following reservoir construction are well documented. Repeated upsurge periods and extended benefits to populations are, however, less understood. We used sclerochronology to investigate fish growth and netting surveys to estimate recruitment and abundance of a lacustrine population of an Australian riverine fish, the Macquarie perch (Macquaria australasica) in Lake Dartmouth. Record low inflows from 1997 to 2008 caused the reservoir to shrink to its lowest volume since construction. Refilling began in 2008, reaching 99% capacity in 2013. We hypothesized that fish growth, recruitment, and abundance would increase in response to the refilling of the lake, reproducing a similar response to the initial filling period. Our findings supported this hypothesis. Macquarie perch growth, recruitment, and abundance were enhanced during the refilling of Lake Dartmouth. Growth, best explained by the effects of dam height, change in dam height, temperature (and their interactions), and recruitment, were highest during the first years of refilling when lake levels and temperatures were low. We propose one or a combination of varying levels of intraspecific competition (low during initial filling and high following population expansion) and improved riverine conditions for reproductive success as the most plausible explanation. Our results suggest extended periods of low lake levels followed by rapid inundation events are likely to enhance recruitment and population growth opportunities for this species. While reservoir construction in general impacts negatively on native fish populations, the potential to offset these impacts for conservation management purposes should be considered.Résumé : Les augmentations rapides de populations de poissons de rivière indigènes associées à la poussée trophique qui suit immédiatement la construction d'un réservoir sont bien documentées. La compréhension de périodes de poussée trophique successives et de leurs avantages pour les populations demeure toutefois plus limitée. Nous avons utilisé la sclérochronologie pour étudier la croissance des poissons et des relevés au filet pour estimer le recrutement et l'abondance d'une population lacustre d'un poisson de rivière australien, la perche de Macquarie (Macquaria australasica) dans le lac Dartmouth. Des débits entrants d'une faiblesse record de 1997 à 2008 ont fait diminuer le volume du réservoir jusqu'au point le plus bas enregistré depuis sa construction. Le nouveau remplissage a débuté en 2008, pour atteindre 99 % de la capacité du réservoir en 2013. Nous avons postulé que la croissance, le recrutement et l'abondance des poissons augmenteraient en réponse à ce nouveau remplissage du lac, une réaction semblable à celle observée durant le remplissage initial. Nos constatations appuient cette hypothèse. La croissance, le recrutement et l'abondance des perches de Macquarie ont augmenté durant le nouveau remplissage du lac Dartmouth. La croissance, qu'ex...

“…At a more local scale, empirical evidence shows that richness and diversity decreases after impoundment, or is lower in reservoirs (Reyes-Gavil an et al 1996;Pyron et al 1998;Gehrke et al 2002;de M erona et al 2005;S a-Oliveira et al 2015;Lima et al 2016a). Conversely, other studies and a recent meta-analysis (Liew et al 2016) found either no change or an increase in richness and diversity after impoundment in reservoirs (Martinez et al 1994;Guenther & Spacie 2006;Irz et al 2006). Many studies have reported an increase in nonnative species, suggesting that non-natives can make up the difference in total species richness in reservoirs (Martinez et al 1994;Johnson et al 2008;Gido et al 2009;Clavero & Hermoso 2010;Liew et al 2016).…”

Dams have varying impacts on fish communities across latitudes: a quantitative synthesis

2019

Dams are recognised to impact aquatic biodiversity, but the effects and conclusions diverge across studies and locations. By using a meta‐analytical approach, we quantified the effects of impoundment on fish communities distributed across three large biomes. The impacts of dams on richness and diversity differed across biomes, with significant declines in the tropics, lower amplitude but similar directional changes in temperate regions, and no changes in boreal regions. Our analyses showed that non‐native species increased significantly in tropical and temperate regulated rivers, but not in boreal rivers. In contrast, temporal trajectories in fish assemblage metrics were common across regions, with all biomes showing an increase in mean trophic level position and in the proportion of generalist species after impoundment. Such changes in fish assemblages may affect food web stability and merit closer study. Across the literature examined, predominant mechanisms that render fish assemblages susceptible to impacts from dams were: (1) the transformation of the lotic environment into a lentic environment; (2) habitat fragmentation and (3) the introduction of non‐native species. Collectively, our results highlight that an understanding of the regional context and a suite of community metrics are needed to make robust predictions about how fish will respond to river impoundments.
