Phytoplankton functional group dynamics explain species abundance distribution in a directionally changing environment

Abstract: The mechanism underlying species abundance distribution (SAD), particularly the characteristics of ''excess of rare species,'' remains controversial. The current equilibrium theory cannot explain the transient dynamics of SAD, which is essential for predicting biodiversity response to environmental changes. Using a unique 32-yr-long phytoplankton community data set from a pelagic site of Lake Biwa, Japan, we show that the dynamics of functional groups driven by environmental variation explain the excess of rar… Show more

“…According to previous dietary analyses, the fish feeds mainly on zooplankton and zoobenthos (gammarids) (Nakanishi & Nagoshi 1984;Briones et al 2012). A major advantage of using this fish species is that unique long-term data were available on prey compositions in both predator diet and the environment (Ishikawa, Narita & Urabe 2004;Nakazawa et al 2010;Hsieh et al 2011;Briones et al 2012;Tsai et al 2014).…”

“…Long-term data were compiled on individual body size of G. isaza (Nakazawa et al 2010), relative composition and body sizes of its major prey (zooplankton and gammarids) in the guts (Briones et al 2012), and relative prey abundances in the environment (Ishikawa, Narita & Urabe 2004;Hsieh et al 2011;Tsai et al 2014), as described below.…”

“…Consequently, phosphorous concentrations in many lakes have declined immensely (Anneville, Gammeter, & Straile, 2005;Pomati et al, 2012;Van Donk et al, 2008). This has, for example, been well studied in Lake Biwa, Japan, for which both biotic and abiotic variables have been tracked over 32 years, showing an increase in nutrient loading in the 1960s and 1970s, followed by a decline during the 1980s, when management practices showed effect (Hsieh et al, 2010;Tsai et al, 2014). High nutrient concentrations are often characterized by high biomass production by few dominant species (Borge et al, 2004), whereas re-oligotrophication increases species richness and community evenness (Pomati et al, 2012) coupled with a decrease in autotrophic productivity or standing stocks (Finger, Wuest, & Bossard, 2013;Verbeek et al, 2018).…”
