A scientometric assessment of 30 years of the Index of Biotic Integrity in aquatic ecosystems: Applications and main flaws

“…Adaptations of Karr's index have been proposed for other environments (Lyons et al, 2000;Beck et al, 2010;Terra and Araújo, 2011) and organisms (Rothrock et al, 2008;Lane and Brown, 2007;Kane et al, 2009), what could explain the higher number of citations of empirical papers that probably resulted from attempts to test the ideas proposed by Karr. Our results show that although the IBI was originally developed for fish, it has influenced the development of analogous indices applied to other taxa, or that combine different taxa in comprehensive assessments of biological condition. Karr (1981) listed several advantages of using fish as bioindicators: their several guilds, their position at the top of the food chain, and the abundance of information on fish.…”

Interactive effects of road salt and sediment disturbance on the productivity of seven common aquatic macrophytes

“…We conducted experiments on seven macrophyte species that are common to freshwater lakes in the north‐eastern USA. Potamogeton robbinsii (Robbin's pondweed) is commonly found in muddy areas of wetlands and is considered highly intolerant of anthropogenic disturbances (Beck, Hatch, Vondracek, & Valley, ). A field survey of Canadian lakes rarely found it in waters with concentrations greater than 3 mg Cl − L −1 (Pip, ).…”

A preliminary evaluation of lake morphometric traits influence on the maximum growing depth of macrophytes

“…This observation may also have more extensive implications and effects on ecological monitoring programs. The area of lakes can easily be assessed by means of open source GIS systems, and the inclusion of a lake's area in ecological macrophytic multimetric indices (Pall and Moser, 2009;Beck et al, 2010) might help to improve the accuracy of monitoring programs. We believe that the elaboration of macrophytic measurements specifically calibrated according to lake area may lead to a more ef- fective evaluation of lake conservation status.…”
