“…However, few studies have examined the colonization and use of half-logs by macroinvertebrates in warmwater stream systems. While previous studies have shown increases in abundance, biomass, taxa richness, and diversity of macroinvertebrates associated with LWD accumulations (Armitage et al, 2001;Braccia & Batzer, 2001;Benke & Wallace, 2003;Johnson & Kennedy, 2003;, it is not clear if these results are applicable to macroinvertebrate colonization of halflogs. The objectives of this study were to: (1) determine the rates and patterns of aquatic macroinvertebrate colonization on half-logs; (2) examine changes in aquatic macroinvertebrate community composition on half-logs among different land-use types; and (3) document changes over time and across a disturbance gradient among aquatic macroinvertebrate functional feeding and tolerance guilds utilizing half-logs.…”

“…Half-logs in (2008) 605:193-207 203 our streams were the most stable substrate available for colonization during the time immediately following the first flood event, which explains their early colonization in tributaries of the upper Wabash River where natural LWD was nearly absent. Seasonal changes in macroinvertebrate populations can develop due to thermal regime, current velocity, energy inputs, and life-history patterns (Shaw & Minshall, 1980;Delong & Brusven, 1998;Armitage et al, 2001). In their study of the River Frome, England, Armitage et al (2001) reported the highest abundances of aquatic macroinvertebrates in late spring and the greatest taxa richness in late summer.…”

Macroinvertebrate community response to large-woody debris additions in small warmwater streams

Half-logs are a common restoration tool used to provide cover for fish in degraded streams. These structures may also provide a stable substrate for biofilm production and aquatic macroinvertebrate colonization. Half-logs (N = 108) were installed into nine streams of the upper Wabash River basin, Indiana, in July 2003 to examine changes in aquatic macroinvertebrate community composition and functional guilds under varying land-use types. Following installation, half-logs were colonized and showed statistically significant increases in both relative abundance and taxa richness of macroinvertebrates over time. The number of Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa collected from half-logs, as a percentage of total community composition, was positively related to the percentage of canopy coverage across streams and the relative abundance of shredder taxa utilizing half-logs decreased significantly with increasing canopy coverage. Forest streams exhibited significantly lower relative abundances of individuals colonizing half-logs (mean = 14.9 taxa/0.25 m 2 ) than fallow field and agricultural streams (mean = 29.5 and 33.1, respectively). The percentage of pollution-tolerant taxa using half-logs was highest in fallow field streams (mean = 18.4%), followed by forest and agriculture systems (mean = 15.9% and 13. 9%, respectively). These results indicate that half-logs were colonized by aquatic macroinvertebrates and exhibited changes in community composition and functional feeding guilds over time and across land-use types. The extent of colonization and use of half-logs was largely dependent upon the pre-existing in-stream habitat quality and the predominant land-use type.

“…These processes may generate a high diversity of species, as it is established in the intermediate disturbance hypothesis (Connell, 1978), because bankside provides refuges during periods of disturbance (Coregino et al, 1995;Rempel et al, 1999;Armitage et al, 2001;Robinson et al, 2002). In the central channel of the Ctalamochita River, floods may cause a high disturbance since the substrate is easily removed by the current.…”

“…Habitats associated with bankside may greatly contribute to faunal diversity (Corigliano, 1989;Ward, 1989;Malmqvist, 2002) by providing refugia during periods of high flow (Coregino et al, 1995;Rempel et al, 1999;Robinson et al 2002). The combined effects of bank morphology, seasonal growth of macrophytes and discharge result in a highly diverse and dynamic environment offering a wide range of ecological niches for the faunal community (Armitage et al, 2001).…”

Aquatic macroinvertebrates living in anastomosing lowland rivers use different habitats and respond differently to the hydrological regime. In this paper, the structure and composition of benthic, drifting and marginal macroinvertebrate assemblages are analyzed in the lowland river Ctalamochita (Co´rdoba, Argentina). The assemblages were studied in an annual cycle; a comparison among the composition of benthos, drift and marginal fauna was carried out; and size structure of the assemblages was characterized. Samples were obtained from two sites: a rural and an urban site. In total 73 taxa of aquatic macroinvertebrates were collected. Benthos was characterized by Chironomidae and Oligochaeta; marginal fauna was mainly constituted by Coleoptera, Heteroptera, Decapoda, the Trichoptera Nectopsyche sp., Ephemeroptera and Odonata. Drifting assemblage was composed by macroinvertebrates from local and remote upstream benthos, and from the marginal zone. Marginal fauna diversity was higher than benthos and drift. Total biomass of the assemblages pooled together was relatively equitably among size classes. Larger size classes consisted of organisms from the marginal zone whereas the smallest ones were composed by benthic and drifting organisms. In the study area there is habitat partitioning in the lateral dimension of the river. Marginal fauna was more diverse due to the asymmetry of transport and deposit processes, which generate a heterogeneous habitat in the bankside. The relation between fine substrate and high current velocity determines an unstable habitat in the central channel, which makes colonization by benthic macroinvertebrates difficult.

“…These results confirm that the structure of banks can influence the invertebrate community, as was also demonstrated in the work of Naura & Robinson (1998), in which the ability of RHS features in predicting crayfish occurrence was investigated. Armitage et al (2001) found that the bank side is a dynamic environment where communities change in relation to the growth of bank side vegetation and its concomitant effect on flow, with bank structure having a direct effect on invertebrates abundance and number of taxa. ASPT is negatively related to channel geometry modification (i.e.…”

The UK River Habitat Survey (RHS) method for the assessment of hydro-morphological features was applied within the EU STAR project simultaneously with the collection of biological data. A subset of data from 79 sites affected by hydro-morphological alteration and belonging to 7 different stream types was analysed. The different features recorded within RHS were evaluated separately considering the characteristics associated with banks, channel and riparian zone. Different scores were assigned to selected features representing hydro-morphological alteration and naturalness of habitat. The ability of the different compartments to represent the quality gradient of sites was investigated. In addition, the link between macroinvertebrate community and hydro-morphological data was investigated, directly relating indices and metrics calculated from taxa list collected in a site to scores assigned to the RHS features. The sections highly affected by morphological alteration were channel geometry and bank profile. Metrics showing the best correlation with the features selected were EPT taxa, ASPT and ICMi (Inter-calibration Common Metric index). Among the indices studied, the HQA score (Habitat Quality Assessment) apparently played the most important role in structuring biological communities and the lentic-lotic character of rivers was also important.
