The Development of An Ecological Quality Assessment and Classification System for Greek Running Waters Based on Benthic Macroinvertebrates

Morphological and free amino acid profile variability, as a tool for stock identification among farmed rainbow troutOncorhynchus mykissof different origin

“…Specifically, GLM analyses revealed a significant correlation of body shape with aquaculture origin, water temperature, zones and the FAAs His and Arg. According to the classification of Greek rivers in three zones considering their hydrological, chemical, geological and climatic features (Skoulikidis, ; Skoulikidis, Amaxidis, Bertahas, Laschou & Gritzalis, ; Skoulikidis, Gritzalis, Kouvarda & Buffagni, ) and the apparent separation in two groups obtained by the CVA analysis, it was revealed that the first group had fish stocks which stemmed from north‐eastern and north‐central territories (Zones 1 and 2) in contrast to the second group whose populations derived from north‐eastern and western territories (Zones 1 and 3) respectively (Figure ). Therefore, one possible explanation is that morphological variation was primarily driven by environmentally induced differences among these two groups supporting the likelihood of being the result of phenotypic plasticity (Swain & Foote, ).…”

“…Map of Greece showing the sampling sites of farmed‐rainbow trout, the three core geological‐chemical‐climatic zones (Skoulikidis, ; Skoulikidis et al., , ) and the two groups of fish populations according to geometric morphometrics and free amino acid profile analyses. The unhatched portion corresponds to the first group and the hatched portion to the second group.…”

Impact of EU Environmental Policy Implementation on the Quality and Status of Greek Rivers

“…River water quality on a country-wide scale has been fairly studied in Greece, either focusing on physicochemical parameters, major ions, and nutrients [3,[11][12][13][14][15][16] or trace elements and hazardous substances [3,[16][17][18][19][20]. On the contrary, country-wide, or nearly country-wide studies regarding riverine ES are scarce and refer to times prior to implementing the NMP [21,22]. This study attempts to fill this gap by providing historical and up-to-date information on the ES of several representative Greek rivers dispersed throughout the country.…”

Application of the biotic index IBE-IOC for water quality assessment in wadeable streams in south-east Brazil

“…Today in many countries more complex multimetric indexes are used and in the Rio de Janeiro State (Brazil) a Multimetrix Index for Serra dos Órgãos Mountains (SOMI) (Baptista et al, 2007) was proposed, but its complex calculation system difficults extensive application in a development country. An adaptation of IBE´s methodology could represent a rapid and costeffective assessment instrument and simple tools for use as routine monitoring, and could be employed routinely in large monitoring plans, while a quantitative approach to community-level analysis could be used only in cases of particular interest or like a metric in multimetric indexes (Fenoglio et al, 2002, Vlek et al, 2004, Skoulikidis et al, 2004, Baptista et al, 2007.…”
