“…In brief, this dataset included seasonal macroinvertebrate data, seasonal fine sediment data, and water chemistry data (mean of the preceding 12 months) that were collected during routine monitoring by the Environment Agency in 2006. For the present study, more detailed macroinvertebrate abundance data were obtained from the Environment Agency, for samples collected in the autumn, along with fine sediment data based on the mean of spring and autumn visual estimates, and Environmental Quality Ratios (based on the observed and expected scores-calculated using RICT) for an index designed to indicate the effects of organic pollution (WHPT index, Paisley et al, 2014). All 754 sites used in the present study were located on independent water bodies, as detailed by the water body names and grid references provided by the Environment Agency.…”

Anthropogenic modifications of sediment load can cause ecological degradation in stream and river ecosystems. However, in practice, identifying when and where sediment is the primary cause of ecological degradation is a challenging task. Biological communities undergo natural cycles and variation over time, and respond to a range of physical, chemical and biological pressures. Furthermore, fine sediments are commonly associated with numerous other pressures that are likely to influence aquatic biota. The use of conventional, non-biological monitoring to attribute cause and effect would necessitate measurement of multiple parameters, at sufficient temporal resolution, and for a significant period of time. Biomonitoring tools, which use low-frequency measurements of biota to gauge and track changes in the environment, can provide a valuable alternative means to detecting the effects of a given pressure. In this study, we develop and test an improved macroinvertebrate, family-level and mixed-level biomonitoring tool for fine sediment. Biologically-based classifications of sediment sensitivity were supplemented by using empirical data of macroinvertebrate abundance and percentage fine sediment, collected across a wide range of temperate river and stream ecosystems (model training datasetn=2252) to assign detailed individual sensitivity weights to taxa. An optimum set of weights were identified by non-linear optimisation, as those that resulted in the highest Spearman’s rank correlation coefficient between the index (called the Empirically-weighted Proportion of Sediment-sensitive Invertebrates index; E-PSI) scores and deposited fine sediment in the model training dataset. The family and mixed-level tools performed similarly, with correlations with percentage fine sediment in the test dataset (n=84) ofrs=−0.72 andrs=−0.70p<0.01. Testing of the best performing family level version, over agriculturally impacted sites (n=754) showed similar correlations to fine sediment (rs=−0.68p<0.01). The tools developed in this study have retained their biological basis, are easily integrated into contemporary monitoring agency protocols and can be applied retrospectively to historic datasets. Given the challenges of non-biological conventional monitoring of fine sediments and determining the biological relevance of the resulting data, a sediment-specific biomonitoring approach is highly desirable and will be a useful addition to the suite of pressure-specific biomonitoring tools currently used to infer the causes of ecological degradation

“…Odonates have been used extensively as a bioindicator group of habitat quality (Clark & Samways, 1996;Sahlén & Ekestubbe, 2001;Foote & Rice Hornung, 2005;Subramanian et al, 2008;Clausnitzer et al, 2009;Dolný et al, 2011) and are one of the taxa included in the Biological Monitoring Working Party (BMWP) score system (Biological Monitoring Working Party, 1978). The BMWP score system has been used as a biological classification system for river pollution surveys in UK since 1980 (Paisley et al, 2014). The revised BMWP system includes Calopterygidae, Platycnemididae, Coenagrionidae, Cordulegastridae, Aeshnidae and Libellulidae (see Paisley et al, 2014 for the scores of each group).…”

ISSN (online): 1802-8829http://www.eje.cz gate current research on the impacts of urbanisation using odonates as a model group. First, we will present a brief overview on the impacts of urbanisation on terrestrial and freshwater ecosystems, then we conduct a systematic literature review regarding odonates in urban environments and outline the plausible effects on odonates, followed by the use of odonates as bioindicators, the conservation value of urban wetlands for odonates, a summary of evolutionary strategies for species to cope with urban stressors, and fi nally we conclude by identifying research needs. THE EFFECTS OF URBAN STRESSORS ON TERRESTRIAL AND FRESHWATER ECOSYSTEMSThe wide range of impacts associated with urbanisation indicates that it exerts a considerable effect on terrestrial biodiversity. Most studies show that species richness and evenness is reduced in highly urbanised regions, depending on the taxonomic group observed, degree of urbanisation, and spatial scale of analysis (McKinney, 2002(McKinney, , 2008. For example, butterfl ies (Ruszczyk, 1987;Ruszczyk & De Araujo, 1992; Blair & Launer, 1997) and ground arthropods (McIntyre et al., 2001) show this tendency. The general pattern of biodiversity decrease in cities is probably due to the fact that over 80% of land in city cores is covered by buildings and pavements, with the remain- Abstract. The expansion of urban areas is one of the most signifi cant anthropogenic impacts on the natural landscape. Due to their sensitivity to stressors in both aquatic and terrestrial habitats, dragonfl ies and damselfl ies (the Odonata) may provide insights into the effects of urbanisation on biodiversity. However, while knowledge about the impacts of urbanisation on odonates is growing, there has not been a comprehensive review of this body of literature until now. This is the fi rst systematic literature review conducted to evaluate both the quantity and topics of research conducted on odonates in urban ecosystems. From this research, 79 peer-reviewed papers were identifi ed, the vast majority (89.87%) of which related to studies of changing patterns of biodiversity in urban odonate communities. From the papers regarding biodiversity changes, 31 were performed in an urban-rural gradient and 21 of these reported lower diversity towards built up city cores. Twelve of the cases of biodiversity loss were directly related to the concentrations of pollutants in the water. Other studies found higher concentrations of pollutants in odonates from built-up catchments and suggested that odonates such as Aeshna juncea and Platycnemis pennipes may be candidate indicators for particular contaminants. We conclude by identifying current research needs, which include the need for more studies regarding behavioural ecology and life-history traits in response to urbanisation, and a need to investigate the mechanisms behind diversity trends beyond pollution.
