“…As expected, IM9 presented the lowest score magnitude fluctuations, because it is a multimetric index composed of three metric categories (ASPTtolerance, GOLD-composition and TRICF-richness), which compensates for the less discriminatory power of each component metric. Those results confirmed previous studies about better performances of multimetric indices when compaired to single metrics (Paller & Specht, 1997;Maxted et al, 2000;Klemm et al, 2002) The multimetric index IM9, developed for temporary southern Portuguese streams (Pinto et al, 2003) confirmed its robustness when compared with common European metrics (AQEM consortium, 2002) along a wider period of time which included an unpredicted flood and summer flow interruption.…”

The generalization of ecological results from temporary streams needs the study of those ecosystems across a broad scale of running waters, covering the geographical ecological constraints involved (e.g., precipitation, temperature and geology). For the particular situation of Mediterranean streams in Southern Europe, high changes in water level, with unpredicting flood events, represent an important factor determining the structure and function of Mediterranean streams. This variability, inducing accentuated changes in the macroinvertebrate community, tends to influence the assessment methodologies. A set of metrics commonly used in Europe to assess organic degradation (Shannon-Wiener index, evenness, richness, BBI, IBE, BMWP , ASPT , DSFI, EPT, number of Trichoptera families, percentage of Gasteropoda, Oligochaeta and Diptera) and a multimetric index (IM9) developed to assess organic degradation in southern siliceous Portuguese basins were tested to evaluate quality at two contrasting sites (one unimpaired and another impaired by an identified point source of pollution). The multimetric index (IM9) composed by: ASPT (average score per taxon); GOLD (one minus percentage of Gasteropoda, Oligochaeta and Diptera); and TRICF (number of Trichoptera families), was the most suitable assessment methodology. IM9 presented a quite stable temporal pattern from February in late winter until June in early summer, even under the effect of episodic floods. A stepwise regression showed that most of tested metrics were significantly related to environmental variables (soluble reactive phosphorous, dissolved inorganic nitrogen and dissolved oxygen). Only richness, IBE and BMWP were not significantly influenced by environmental variables. Future research must be done covering the complete gradient of organic degradation, including the extension of multimetric assessment methodologies to temporary streams located in other regions under different geological and climatic conditions.

“…The metrics were based on the structure, composition, and assemblage pattern of benthic macroinvertebrate species (KERANS and KARR, 1994;BARBOUR et al, 1999;MAXTED et al, 2000;BLOCKSOM et al, 2002;KLEMM et al, 2003). The B-IBI metrics were categorized into six main groups, namely richness measures, composition measures, tolerance measures, feeding measures, habitat measures and biodiversity index (Table 1).…”

“…First, we used the quadrisection scaling system (DESHON, 1995;MAXTED et al, 2000), which used a 6, 4, 2, 0 point system: 1 st quarter of the range = 6 points, 2 nd quarter of the range = 4 points, 3 rd quarter of the range = 2 points, and the remainder of the range = 0 points (see Fig. 3).…”

The aim of this study is to develop a benthic index of biotic integrity (B-IBI) to help understand how the increasing anthropogenic pressure may impact the subtropical Xiangxi River in China. Benthic macroinvertebrate and environmental surveys were conducted at 77 sites in early summer 2004. Each collection site was categorized as reference or impaired based on physical, chemical, biological, and land-use information. Six non-redundant metrics from 35 metrics were used to differentiate between reference and impaired sites. We selected six metrics for the final IBI. The scoring criteria of each metric were normalized based on the quadrisection and 0-10 scaling systems. Both scaling methods were used to assess the aquatic health of each site in the Xiangxi River watershed. The results showed that most sites were in fairly poor condition. Furthermore, we identified the relationship between B-IBI metrics, water-quality, and land-use variables with a principal component analysis. A composite of nutrients and land-use intensity explained most variances. These results suggest that the B-IBI may be a suitable method for assessing river conditions within the subtropical Xiangxi River in central China. IntroductionAquatic ecosystems, and their biological assemblages, continued to be degraded globally from anthropogenic activities in their watersheds (GANASAN and HUGHES, 1998;KARR, 1999). Part of the decline in water resources stems from insufficient consideration of their biological structure and function (KARR, 1999;STODDARD et al., 2006). Some factors have been reported which are linked to river degradation. Physical and chemical factors may be related to biological changes (MULLINS, 1999). Water quality may only partially reflect environmental impact (BOZZETTI and SCHULZ, 2004). Researchers increasingly include quantitative biological indicators (JOY and DEATH, 2004;ROSET et al., 2007). Biological indicators may reflect the intensity of anthropogenic stress and have been used as a tool in risk assessment and evaluation of human induced changes in freshwater ecosystem (KAMDEN-TOHAM and TEUGELS, 1999

“…The small number of applied/conservation papers that did not clearly fit at least one of the main subject headings were classified as Miscellaneous. We excluded purely faunistic or nonscientific surveillance investigations and the many studies in which results were reported for odonates but that did not explicitly target odonates (e.g., Gee et al 1997, Maxted et al 2000, King and Richardson 2007. However, we did count studies of broader issues that used odonates and other taxa as model or target groups (e.g., Siegfried 1993, Richter et al 1997, Palmer 1999, Le Viol et al 2009, Rosset et al 2013.…”

The academic study of dragonflies and damselflies (odonatology) is well established, but relatively limited attention has been given to odonates in the context of applied ecology and conservation science. We used the Web of Science ™ and Odonatological Abstract Service (ISSN 1438-0269) to capture trends in primary literature, characterize study features (habitats, life stages, etc.), identify research themes, and suggest future directions for odonatology in freshwater applied ecology and conservation science. We found no papers in this area prior to 1980, and 411 papers from 1980 through 2013. Nearly 75% of these papers were recent (since 2005) and >40% were very recent (since 2010). We identified several broad and overlapping research themes: 1) model taxa, 2) tools and indicators, 3) odonate-centered work, and 4) methodological issues and improvements (field sampling, data modeling/simulation, conservation/landscape-scale genetics). We found more reliance on fieldbased observational approaches than experiments and model-driven exercises, although the number of papers using model-driven exercises is rapidly increasing. We found a strong focus on adult stages, odonate assemblages, the Odonata as a whole, and studies of particular species. We identified research priorities in areas such as ecological valuation and management, monitoring and assessment, climate change and landscape planning, concordance with other taxa, effects of urbanization, data modeling/simulation, and rare-species ecology and conservation. To help establish an identity and facilitate communication, we suggest naming this diverse realm "applied odonatology". We think applied odonatology has a good future for a range of topics from conservation genetics and population ecology to assessments of anthropogenic impacts and the conservation of biodiversity. Key words: dragonflies, assessment, climate change, monitoring, landscape planning, freshwater health, biodiversity conservationThe academic study of dragonflies and damselflies (odonatology) is well established. However, relatively few odonatologists work outside of taxonomy and systematics, behavioral ecology, evolutionary ecology, and other prominent areas of classical research. The major books (Corbet 1999, Córdoba-Aguilar 2008), treatises (e.g., Corbet 1980, Stoks and Córdoba-Aguilar 2012), and flagship journals of odonatology reveal a productive legacy, but also relatively limited attention to matters of applied ecology and conservation science. For example, <5% of the 275 papers published during [2009][2010][2011][2012][2013] in Odonatologica and the International Journal of Odonatology are clearly relevant to applied ecology or conservation science. Nevertheless, the relatively few odonatologists working in this area and researchers based in other fields who often or sometimes use odonates as principal study subjects are making important contributions.A growing body of dragonfly-related research deals with the study or use of odonates in the context of freshwater applied ecolo...
