“…Colmation of hyporheic sediments is widely acknowledged to lead to reductions in the diversity and density of invertebrates within the hyporheic zone (Richards & Bacon, 1994;Strayer et al, 1997;Weigelhofer & Waringer, 2003;Bo et al, 2007). Increasing interstitial fine sediment concentrations have been documented to increase divergence of benthic and hyporheic communities (Descloux et al, 2013); a feature which was evident in this study with 17 taxa being unique to the benthic community.…”

“…Substrates containing less fine sediment at the tail of riffles in this study supported significantly greater abundances of scrapers (Relyea et al, 2000;Bo et al, 2007). The presence of fine sediments can inhibit access to trophic resources, with some species in other studies reported to be confined to areas of clean gravel (Wood & Armitage, 1999;Rabeni et al, 2005).…”

Benthic and hyporheic macroinvertebrate distribution within the heads and tails of riffles during baseflow conditions

The distribution of lotic fauna is widely acknowledged to be patchy reflecting the interaction between biotic and abiotic factors. In an in situ field study, the distribution of benthic and hyporheic invertebrates in the heads (downwelling) and tails (upwelling) of riffles were examined during stable baseflow conditions. Riffle heads were found to contain a greater proportion of interstitial fine sediment than riffle tails. Significant differences in the composition of benthic communities were associated with the amount of fine sediment. Riffle tail habitats supported a greater abundance and diversity of invertebrates sensitive to fine sediment such as EPT taxa. Shredder feeding taxa were more abundant in riffle heads suggesting greater availability of organic matter. In contrast, no significant differences in the hyporheic community were recorded between riffle heads and tails. We hypothesise that clogging of hyporheic interstices with fine sediments may have resulted in the homogenisation of the invertebrate community by limiting faunal movement into the hyporheic zone at both the riffle heads and tails. The results suggest that vertical hydrological exchange significantly influences the distribution of fine sediment and macroinvertebrate communities at the riffle scale.

“…The difference was probably yielded because in the mentioned studies the particles were larger (sand) and deposited more rapidly so turbidity is not even reported as a measure of stress. Also, fine sediments cause a more efficient siltation of interstices, especially in riffles which are abundant at our study site, rendering them unsuitable for most indigenous taxa (Bo et al 2007;Weigelhofer & Waringer 2003).…”

“…Sedimentation and siltation is an overwhelming stress for the native invertebrate assemblages (Wood & Armitage 1997;Weigelhofer & Waringer 2003). Primary producer's abundance is lowered and stream metabolism is changed, food quality for macroinvertebrates degrades and interstices are filled, rendering these habitats inadequate for macroinvertebrates (Quinn et al 1992;Parkhill & Gulliver 2002;Bo et al 2007). We therefore expected a decrease in macroinvertebrate abundance and diversity downstream of the quarry.…”

Destructive effect of quarry effluent on life in a mountain stream

Quarrying is a widespread method for acquiring construction material. The studies of quarrying effects to date have been conducted mostly in the fields of geology, (hydro)geochemistry and landscape management while ecological studies on effects of quarrying are surprisingly few. The goal of this study was to assess some ecological effects of quarry mining on mountain stream habitats. The study was performed at Bistra Stream on Medvednica Mountain in NW Croatia. The quarry is located 3 km downstream from the spring. Samples were taken at four sites on four dates during the spring of 2006. Standard physico chemical parameters were measured and triplicate benthos samples were taken using a 30 × 30 cm Surber sampler. Turbidity, pH and temperature increased significantly downstream of the quarry. All biocenotic descriptors decreased significantly downstream of the quarry including total taxa (by 60%), total number of individuals (by 85%), diversity index (by 56%). The most important cause of such changes in the macroinvertebrate assemblage structure was the change in pH and turbidity. The magnitude of changes in the macroinvertebrate assemblage structure was due to the extremely long duration of disturbance. However, we believe that the recovery of aquatic assemblages, upon closure of the quarry, would be fast and successful because of nearby streams that may serve as a recolonizing source.

“…is a representative 60-meter long stretch, with a mixture of riffles and runs, no deep pools, but with a moderate and constant slope. Riverbed width is approximately 4.0-5.0 m, and the substrate had the following particle composition: 10% sand, 30% gravel, 50% pebbles and 10% boulders (see Bo et al, 2007 for further details).…”

-The influence of day/night conditions on individual animal/plant species has been widely studied, but diel cycle studies of the entire stream macroinvertebrate community are extremely rare. This study explored potential dissimilarities between daytime and nighttime macroinvertebrate assemblages by extensive fieldwork conducted in the Lemme stream, a natural water course of NW Italy. Here numerous structural and functional metrics (richness, abundance, biomass, indicator taxa, composition, biomonitoring values and feeding groups) were evaluated at the family level. Small-scale environmental variables were investigated to understand possible differences between macroinvertebrate assemblages in the daytime/nighttime. After collecting and identifying 21 459 organisms of 50 taxa, Chironomidae (Diptera) was the most abundant under both day and night conditions. Our findings stressed that similar results and biological information on daytime/nighttime data were obtained. No marked differences could be related to various factors: heterotrophic condition of small-order streams, presence of aquatic predators under night and day conditions, absence of taxa with a specific phototaxis. Of all the environmental variables, velocity was always the most important in both situations, with some differences detected in the importance of the second variable (riverbed substrate diameter). This research, and future studies on different conditions and geographic areas, will contribute knowledge on stream macroinvertebrate diel activity, and provide useful information about efficient sampling strategies.Key-words: aquatic ecology / diel cycle / lotic systems / aggregation / benthic invertebrates Résumé -Le changement ne survient pas dans une nuit : étude sur la communauté de macro-invertébrés d'un cours d'eau. L'influence des conditions jour/nuit sur les espèces animales et végétales a été largement étudiée, tandis que les études à propos du cycle diurne de l'entier de la communauté des macro-invertébrées fluviales sont extrêmement rares. Dans le cadre de cette étude, les différences potentielles entre les assemblages de macro-invertébrés lors du jour et de la nuit ont été explorées grâce à un travail de terrain très appuyé. L'expérience a été conduite près du Lemme, un cours d'eau naturel situé dans le nord-ouest de l'Italie où des nombreux indicateurs structurels et fonctionnels (richesse, abondance, biomasse, taxons indicateurs, composition, valeurs de biosurveillance et groupes d'alimentation) ont été évalués au niveau Famille. Les variables environnementales à petite échelle ont été évaluées aussi dans le but de comprendre les différences possibles entre les assemblages de macro-invertébrés durant le jour et la nuit. Un total de 21 459 organismes appartenant à 50 taxons ont été collectés et identifiés, montrant que le Chironomidae (Diptera) est le plus présent le jour comme la nuit. Nos trouvailles nous ont montré que des résultats similaires ont été obtenus dans des conditions diurnes comme nocturnes. L'absence de différ...
