Trophic Impact

SummaryDam reservoirs often supply high amounts of plankton to downstream reaches, leading to a critical shift of trophic origins of stream ecosystems from natural sources (e.g. attached algae and terrestrial inputs) to reservoir-oriented plankton. Although this is a widely observed phenomenon, previous studies focused only on lotic habitats (e.g. riffles) rather than lentic habitats such as backwaters and isolated ponds (IP).Using a stable isotope three-source mixing model, we evaluated trophic contributions of reservoir-derived plankton, epilithon and terrestrial leaves to stream macroinvertebrates at four dam outlet reaches and two reference reaches in the Natori River catchment, Japan. We compared four different habitat types co-occurring within the reaches: lotic habitat (riffle and pool), bar-head (BH) lentic habitat, bar-tail (BT) lentic habitat (backwater) and isolated pond (IP) on sandy bars.The trophic contributions of reservoir-derived plankton were significantly lower in lentic habitats (BH, 15.4%; BT, 10.4%; IP, 9.1%) than in lotic habitats (mean, 27.7%). This was especially notable for filter feeders that feed on suspended fine particulate organic matter (SFPOM). The three-source model analysis indicated a lower biomass proportion of dam plankton in lentic SFPOM (mean, 21.2%) than in lotic SFPOM (mean, 35.6%). This difference in SFPOM composition was reflected in the lower trophic contribution of dam plankton to lentic filter feeders.The abundance ratio of filter feeders in the community was decreased in lentic habitats, while the abundance ratios of collector-gatherers, scrapers and shredders were increased. Macroinvertebrates in lentic habitats fed on sources less mixed with reservoir-derived plankton (e.g. benthic coarse particulate organic matter [BCPOM], benthic fine particulate organic matter [BFPOM] and epilithon); therefore, the trophic impact of reservoirs was indistinctive at the community level, indicating that lentic habitats can function as trophic refugia to mitigate the trophic impact of reservoirs.Because lentic habitats were decreased in area (accounting for 5.7% of average total area) in the downstream reaches of dams due to riverbed degradation, lentic habitats must be created in order to restore the trophic impact of reservoirs in river ecosystems.

Transport of coarse particulate organic matter (CPOM) derived from forest litterfall has been hardly studied in rivers, unlike fine particulate organic matter (FPOM) or dissolved organic matter (DOM). Yet, many rivers are dammed or run into lakes, and there is growing evidence that CPOM accumulation in river delta participates substantially in ecological processes such as greenhouse gas emissions of lakes and reservoirs. We investigated the transport of CPOM and FPOM by the Leysse River (discharge from 0.2 to 106 m3 s−1) to Lake Bourget (France) in relation to aerial litter deposition, river network length, and discharge. Over a 19-month study period, the volume-weighted mean CPOM and FPOM concentrations were 1.3 and 7.7 g m−3, respectively. Most CPOM and FPOM transport occurred during major flood events, and there were power relationships between maximum discharge and particulate organic matter (POM) transport during these events. The annual export of CPOM (190 t AFDM) was 85% of the litter accumulation in autumn on permanent sections of the riverbed (224 t AFDM), which suggests that export is a major process compared to breakdown. Export of CPOM was 1.25 t yr−1 km−2 of the forested catchment area. This study highlights the need to account for long-range CPOM transport to describe the fate of litter inputs to streams and to quantify the organic matter input and processing in lakes and reservoirs.
