“…McLachlan, Brennan & Wotton (1978) and Mattingly, Cummins & King (1980) found a positive relationship between the growth rate of chironomids and both organic matter availability and the size of the particles ingested. Some of this evidence is tied to reproductive output and growth of meiofauna and, as such, is compelling since the importance of organic matter as a resource for biota is best expressed in terms of fitness consequences.…”

Summary Lotic meiofaunal communities demonstrate extremely variable dynamics, especially when viewed at small spatial scales (≤ metres). Given the limited amount of research on lotic meiofauna, we chose to organise our discussion of their small‐scale spatial patterns around the dominant factors we believe drive their spatial distributions in streams. We separate scale‐dependent effects that structure lotic meiofauna into biotic factors (e.g. predation, food quantity/quality, dispersal) and abiotic factors (e.g. local flow dynamics and substratum characteristics). The impact of predation on the distribution of meiofauna varies with the scale over which predators forage (e.g. fish predation influences meiofauna in different ways and at broader spatial scales than do invertebrate predators), the type of streambed substrata in which the predator‐prey interactions occur, and the dispersal ability of different meiofauna. The latter is greatly influenced by predator and prey (meiofauna) interactions with the flow environment. Organic matter influences the small‐scale distribution of meiofauna in streams. Both its quality as food (as indicated by C:N content, ATP content, or microbial biomass) and its spatial distribution on the streambed, influence meiofauna patchiness, community structure and life history characteristics. As a habitat, the structure that organic matter provides (e.g. wood or leaves) can influence predator‐prey interactions, offer materials for case‐building and offer refugia during disturbance events ‐ all of which influence the small‐scale spatial distribution of meiofauna. Stream flow influences the distribution of meiofauna at broad scales (10s–100s of metres), primarily because of the high susceptibility of meiofauna to passive drift; small‐scale interactions between flow and substrata are also important, however, particularly at more localised (≤ metre) scales. At both scales, substratum particle size is important to interstitial‐dwelling fauna, influencing the probability of passive drift by meiofauna as well as local microhabitat conditions (e.g. dissolved oxygen; upwelling/downwelling in the hyporheic zone) and, thus, the small‐scale distribution among microhabitats. In general, the processes governing the distribution of meiofauna at small scales cannot be separated entirely from those processes working at larger scales. A conceptual diagram is presented illustrating the relative importance of various factors in influencing the spatial patterns of meiofauna and over what scales these factors act.

“…These or similar measures are commonly used to quantify the nutritional quality of foods ingested by detritivorous fishes and invertebrates (Odum 1968, Bowen 1979, Cummins 1979, Zimmerman & Wissing 1980, Mattingly et al 1981, Lawson et al 1984, Rasmussen 1984, Roman 1984, Valiela & Rietsma 1984.

“…The nutritional quality of organic detritus ingested by the fish is determined in part by its organic (Mattingly et al 1981) and protein or nitrogen (Bowen 1979(Bowen ,1980 contents. The organic content of the detritus determines the total amount of food available for assimilation, but detritus must also contain sufficient assimilable nitrogen (C:N ratios <17:1, Russell-Hunter 1970) to support fish growth.…”

Nutritional importance of detritivory in the growth and condition of gizzard shad in an Ohio reservoir

SynopsisGizzard shad, Dorosoma cepedianum, in Acton Lake, Ohio, ingested foods of varying nutritional quality during the 19131-1983 growing seasons. Adult (ages 2-4) fish fed on a mixed diet (ORG>30%; C:N<7:1) of zooplankton and organic detritus in early summer, and on detrital materials (ORG<16% ; C:N>ll:l) during the remainder of the growing season. Age 0 (<35 mm standard length) fish ingested only detrital materials. The nutritional quality (ORG = 10 -20%; C:N<11:1) of these foods displayed little seasonal variation, but was higher than that of organic detritus taken by adult fish in late summer and autumn. Growth and condition of gizzard shad were poor when the diet consisted of detrital materials; however, age 4 fish (1983) grew rapidly and condition improved when zooplankton were consumed. These results suggest that ingestion of poor-quality detritus can reduce the growth and condition of gizzard shad in Acton Lake, whereas the seasonal inclusion of high-quality zooplankton in the diet can result in rapid growth and improved condition.

“…Release of particulate organic matter by mussels into the stream benthos has been shown to create food for other organisms (Nichols & Garling, 2000;Raikow & Hamilton, 2001;Howard & Cuffey, 2006). McLachlan et al (1978) and Mattingly et al (1981) showed positive relationships between the growth rates of chironomid larvae and organic matter availability, which suggests that feeding and biodeposition by bivalves can lead to higher benthic productivity of co-occurring species.…”

Suspended material availability and filtration–biodeposition processes performed by a native and invasive bivalve species in streams

Unionid mussels are among the most threatened group of freshwater organisms globally. They are known for their ability to filter food particles from flowing and standing waters. However, invasive bivalve species, such as the Asian clam (Corbicula fluminea) in North America, have the potential to overlap in feeding and potentially out-compete the native species. Yet, the feeding preferences of unionid mussels and C. fluminea are incompletely understood. We hypothesized that Elliptio crassidens (native) and C. fluminea (invasive) would select for specific organic components present within seston. We examined changes in seston (dry mass and ash-free dry mass) resulting from bivalve feeding activity for three size classes of material that were isolated using gravimetric filtration. The treatments were also sub-sampled for flow cytometry (FC) which separated the suspended materials in the stream water into five categories: detritus, heterotrophic bacteria, picoautotrophs, nanoautotrophs, and heterotrophic nanoeukaryotes. Our results indicated that both species of bivalve showed preferences for organic and living materials. E. crassidens preferentially filtered nanoeukaryotes, whose decreases were associated with an increase in Present Address: bacteria. In contrast, C. fluminea preferred smaller materials through selective filtration of picoautotrophs. In addition, both species increased the concentration of large materials toward the end of the experiment because of the suspension of their pseudofeces biodeposits. To our knowledge, this study is the first to examine grazing by bivalve species on natural stream particulate matter using FC. Our results suggest that native and non-native mussels have different functional roles, which has important implications for organic matter processing and food webs in streams.
