Phytoplankton and suitability of derived metrics for assessing the ecological status in a limno-reservoir, a Water Framework Directive nondefined type of Mediterranean waterbody

“…The ecological status of the limnoreservoir was derived with this index according to the defined class boundaries ( Table 2). The PTI was calculated following Phillips et al (2013), assigning to each species its corresponding trophic optimum. We evaluated the response of the different phytoplankton metrics to a trophic gradient and plotted the results of these indices against TP and Chl-a values, as in Marchetto et al (2009) for TP.…”

“…Carvalho et al (2013) evaluated the indicator strength of 6 of these metrics and recommended the use of 3: Chl-a, the Phytoplankton Trophic Index (PTI; Phillips et al 2013), and the absolute cyanobacterial biovolume (Mischke et al 2011). The last 2 metrics were developed based on summer data from multiple lakes across Europe.…”

Ecological status assessment of European lakes: a comparison of metrics for phytoplankton, macrophytes, benthic invertebrates and fish

“…The metrics tested for responses to eutrophication are given in Table 3a and comprise five different metrics for phytoplankton Phillips et al, 2012), three different metrics for macrophytes (Kolada et al, 2011;Dudley et al, 2012), one multimetric index for benthic invertebrates Pilotto et al, 2011) and two multimetric indices for fish (Argillier et al, 2012). Comparison of regression strength and sensitivity for metrics tested for response to eutrophication Linear regression models and t tests of standardised (ztransformed) data were used to compare regression strengths (correlation coefficient r) and response sensitivity (standardised regression slope b1) of the metrics described above.…”

Water colour, phosphorus and alkalinity are the major determinants of the dominant phytoplankton species in European lakes

“…This species has rapidly increased all over the world from tropical to temperate zones (Fabbro & Duivenvoorden., 1996;Chapman & Schelske., 1997;Lagos et al, 1999;Shafik et al, 2001;Briand et al, 2004;Valerio et al, 2005;Bouvy et al, 2006;Fastner et al, 2007;Moustaka-Gouni et al, 2009;Alster et al, 2010;Kokociński et al, 2010;Moisander et al, 2012) limneticus, are particularly known from meso-and eutrophic water bodies and may form water blooms Nixdorf et al, 2003;Reynolds et al, 2002;Cronberg & Annadotter, 2006;Willén, 2007). Phillips et al (2012) classified phytoplankton genera into very tolerant, tolerant, sensitive and very sensitive taxa of high nutrient conditions. Many of the cyanobacterial genera were classified as very tolerant or tolerant.…”
