“…This is in agreement with the virtual lack of direct predation on R. venosa in the study area (ICES 2004;Giberto et al 2007). Concerning C. fluminea, it was identified as a primary consumer, consistent with the expected trophic level phytoplankton and detritus feeders (Karatayev et al 2003;Cerco and Noel 2010), and, in agreement with other studies (Robinson and Wellborn 1988), the model estimated a high EE value suggesting that this species is heavily consumed in the system.…”

“…This species is considered one of the most invasive species in aquatic ecosystems due to its rapid growth, early sexual maturity, short lifespan, high fecundity and its association with human activities (Cataldo and Boltovskoy 1999;Sousa et al 2008). C. fluminea is a filter feeding bivalve, and a decrease in chlorophyll level has been observed above bivalve beds, suggesting that these organisms might act as regulators of phytoplankton biomass (Cerco and Noel 2010).…”

“…Ecological modelling can provide valuable guidance for the description of ecosystem structure and function and for understanding the role of invaders in a community context (Harvey and Karieva 2005;Miehls et al 2009;Cerco and Noel 2010). In this study, we assessed the effects of invasions of R. venosa and C. fluminea in the Río de la Plata by analyzing parameters obtained from a mass-balanced trophic model (Lercari et al 2009) of the Río de la Plata estuary and nearshore oceanic ecosystem using Ecopath software, considering all functional groups in this system, from primary producers to apex predators.…”

“…We would also like to emphasize the utility of Re as a dimensionless parameter for quantifying and comparing siphon flows and the importance of reporting siphon inner diameters, which can be used to calculate inhalant and exhalant Re and velocities and other parameters of interest. Accurate measurements of suspension-feeding rates are crucial for ecosystem models (Cranford et al, 2011;Cerco and Noel, 2010). The wide range in published suspension-feeding rate measurements (Table 2) indicates the need for more robust methods, such as those presented here.…”

“…Detailed studies of inhalant flow are likely to improve parameterizations in ecological models that include suspension feeding (e.g. Cerco and Noel, 2010). Specifically, these studies could be used to identify flow conditions and animal densities at which interactions between neighbors become significant and to scale individual suspension-feeding rates up to population scales.…”

Benthic marine suspension feeders provide an important link between benthic and pelagic ecosystems. The strength of this link is determined by suspension-feeding rates. Many studies have measured suspension-feeding rates using indirect clearance-rate methods, which are based on the depletion of suspended particles. Direct methods that measure the flow of water itself are less common, but they can be more broadly applied because, unlike indirect methods, direct methods are not affected by properties of the cleared particles. We present pumping rates for three species of suspension feeders, the clams Mya arenaria and Mercenaria mercenaria and the tunicate Ciona intestinalis, measured using a direct method based on particle image velocimetry (PIV). Past uses of PIV in suspensionfeeding studies have been limited by strong laser reflections that interfere with velocity measurements proximate to the siphon. We used a new approach based on fitting PIV-based velocity profile measurements to theoretical profiles from computational fluid dynamic (CFD) models, which allowed us to calculate inhalant siphon Reynolds numbers (Re). We used these inhalant Re and measurements of siphon diameters to calculate exhalant Re, pumping rates, and mean inlet and outlet velocities. For the three species studied, inhalant Re ranged from 8 to 520, and exhalant Re ranged from 15 to 1073. Volumetric pumping rates ranged from 1.7 to 7.4 l h for C. intestinalis. We also used CFD models based on measured pumping rates to calculate capture regions, which reveal the spatial extent of pumped water. Combining PIV data with CFD models may be a valuable approach for future suspension-feeding studies.

Drought‐induced changes in flow regimes lead to long‐term losses in mussel‐provided ecosystem services

Extreme hydro-meteorological events such as droughts are becoming more frequent, intense, and persistent. This is particularly true in the south central USA, where rapidly growing urban areas are running out of water and human-engineered water storage and management are leading to broad-scale changes in flow regimes. The Kiamichi River in southeastern Oklahoma, USA, has high fish and freshwater mussel biodiversity. However, water from this rural river is desired by multiple urban areas and other entities. Freshwater mussels are large, long-lived filter feeders that provide important ecosystem services. We ask how observed changes in mussel biomass and community composition resulting from drought-induced changes in flow regimes might lead to changes in river ecosystem services. We sampled mussel communities in this river over a 20-year period that included two severe droughts. We then used laboratory-derived physiological rates and river-wide estimates of species-specific mussel biomass to estimate three aggregate ecosystem services provided by mussels over this time period: biofiltration, nutrient recycling (nitrogen and phosphorus), and nutrient storage (nitrogen, phosphorus, and carbon). Mussel populations declined over 60%, and declines were directly linked to drought-induced changes in flow regimes. All ecosystem services declined over time and mirrored biomass losses. Mussel declines were exacerbated by human water management, which has increased the magnitude and frequency of hydrologic drought in downstream reaches of the river. Freshwater mussels are globally imperiled and declining around the world. Summed across multiple streams and rivers, mussel losses similar to those we document here could have considerable consequences for downstream water quality although lost biofiltration and nutrient retention. While we cannot control the frequency and severity of climatological droughts, water releases from reservoirs could be used to augment stream flows and prevent compounded anthropogenic stressors.
