Response of rotifer functional groups to changing trophic state and crustacean community

Abstract

Information based on taxon-based indices is species-specific while information gained from function-based

Rotifers in Lake Orta: a potential ecological and evolutionary model system

“…In the post-pollution period, after the liming activities in 1989-1990 to 1997, at least 45 species of rotifers were found in the lake (Bonacina and Pasteris, 2001), a comparable number to what is known from the plankton of nearby lakes, unaffected by the levels of pollution of Lake Orta (e.g., Lake Maggiore: ~40, Obertegger and Manca, 2011;Boggero et al, 2014), and within the range of species diversity that is expected for the plankton of an oligotrophic lake at temperate latitudes (Muirhead et al, 2006). Planktonic rotifers present in the recovery phase represented all functional guilds, including filter-feeders, browsers, scrapers, piercers, and even predators such as Asplanchna brightwellii and A. priodonta (Bonacina and Pasteris, 2001).…”

Zooplankton predators and prey: body size and stable isotope to investigate the pelagic food web in a deep lake (Lake Iseo, Northern Italy)

“…Size-specificity is a major trait governing biotic and abiotic interactions within and between the zooplankton (Geller and Müller 1981;Peters, 1983;Porter et al, 1983, Obertegger andManca, 2011). Size-specificity in prey selection characterizes the predatory cladoceran L. kindtii.…”

Multifractal Detrended Fluctuation Analysis of Streamflow in the Yellow River Basin, China

“…The annual periodicity of streamflow time series resulted in the existence of a crossover point using MFDFA method (Figure 3). The STL method provides a graphical view for describing nonlinear trends with seasonal periodicity by using the generalized additive modeling approach [41,42]. This method can be applied to addressing the changes in timing, amplitude, and variance that occur in the seasonal cycle.…”
