1. This paper examines the influence of channel morphology and hydraulics on occurrence diversity 'functional habitats' (also called 'meso-habitats') in semi-natural physically degraded rivers. 2. The depths velocities at which each functional habitat is most likely to be found are described using 'occurrence matrices'. In cases, was associated with distinct depth-velocity conditions. 3. relationship between occurrence, river degradation examined. deviation a site from its predicted natural...
1. This paper explains the background to concepts of instream physical habitat incorporated in River Habitat Surveys. Two independent research threads—physical biotopes and functional habitats—are described representing, respectively, 'top down' 'bottom up' attempts describe use environment by biota. 2. Physical are observed field identification surface flow types, each which has been proved as distinctive hydraulic study; these have Functional habitats derived from invertebrate sampling...
River Habitat Survey (RHS) is a system which records and quantifies the physical vegetational structure of river channels their immediate floodplains. In United Kingdom, where it has been applied since 1990s, brought an understanding state rivers nationally proved to be useful part scientific investigation. It now obvious that such method should more widely, especially in European context, data lacking for many countries there need standard, internationally comparable method. this paper...
The AQEM Project aims to develop a Europe-wide system for monitoring the ecological quality of rivers using macroinvertebrates, satisfy requirements EU Water Framework Directive. Three main types anthropogenic perturbation are being investigated: morphological degradation, water (organic) pollution and acidification (the last is not under investigation in Italy). selection reference impaired study sites discussed. Particular attention paid problems encountered when defining conditions....
Biological assessment metrics and water chemistry measurements are used to quantify the link between stressors their effects on lake ecosystems, for Water Framework Directive. However, correlations often poor. This is seen as major weaknesses of Directive-related monitoring assessment. We analyzed macrophytes, benthic algae, macroinvertebrates, sediment total phosphorus content in littoral six lakes Western Balkans CORINE land use data estimate nutrient enrichment via runoff from adjacent...
Abstract The annual global loss of organic carbon from terrestrial ecosystems into rivers is similar to the stored in soils each year. Dissolved matter (DOM) flows through food web macroinvertebrates, but little known about effect DOM increase on stream webs and how much macroinvertebrates may contribute regulation fluxes rivers. Using a before after control impact (BACI) experimental design, we increased by 12% (+ 0.52 mg C L −1 ) concentration for three weeks adding sucrose, with...
Two out of the three common Asellidae species in Northern Europe are increasing their ranges, aided by humanactivities. Here we report discovery Proasellus coxalis (Dollfuss 1892) new areas Norway and thediscovery meridianus (Racovitza 1919) for first time Nordic countries, verified withDNA barcoding. A new, detailed photo-identification guide to Asellus aquaticus Linnaeus 1758, P. andP. is presented. In addition head pattern, attention drawn female pleopods as an easy way differentiate...
This article examines the Sebasteion – a complex for emperor-worship built in first century AD - Aphrodisias, modern Turkey, and studies its political ideological messages when sensory experiences of spectators are considered. The monument contained geographical representations peoples Roman world placed above portico. Previous this focus upon close repeated visual study to gain an idea powerful empire, but is not how contemporary audience would have experienced it. During religious...
Summary Soils are currently leaching out their organic matter at an increasing pace and darkening aquatic ecosystems due to climate land use change, or recovery from acidification. The implications for stream biogeochemistry food webs remain largely unknown, notably the metabolic balance (biotic CO 2 emissions), reciprocal subsidies between autotrophs bacteria, trophic transfer efficiencies. We a flow web approach test how small addition of labile dissolved affects strength dynamics...
Along six transects in each of lakes across the Western Balkans, we collected data for three groups littoral biological water quality indicators: epilithic diatoms, macrophytes, and benthic invertebrates. We assessed relationships between them environmental pressures: nutrient load (eutrophication), hydro-morphological alteration shoreline, level variation, separating effect individual continuous explanatory variables. Lake total phosphorus concentration (TP) showed substantial variation but...
