A compendium of cell and natural unit biovolumes for >1200 freshwater phytoplankton species

Abstract: Abstract. Cell size determination is a critical part of sampling phytoplankton communities, as size is both a fundamental trait determining species' ecological niches and a quantity necessary for generating unbiased estimates of community composition. The sizes of algal cells span orders of magnitude, driving variation in growth parameters, sinking rates, herbivore defense, and biogeochemical roles. Size variation occurs at both intra-and interspecific levels. Many central questions in community and ecosystem … Show more

“…Ingestion rates expressed in units of cells per Epischura hr −1 were obtained by multiplying clearance rates by mean prey densities during experiments, and ingestion rates were compared among prey categories using one‐way ANOVA and Tukey post hoc tests. Epischura ingestion rates for each prey taxon were also expressed in units of carbon derived from cell densities and cell volumes of diatoms ( Synedra acus = 978 μm 3 , Kremer, Gillette, Rudstam, Brettum, & Ptacnik, ; Lindavia minuta = 482 μm 3 , equation in Hillebrand, Durselen, Kirschtel, Pollingher, & Zohary, ) and ciliates ( Limnostrombidium viride , large form = 39,250 μm 3 , Obolkina, ) as well as published conversion factors (diatoms = 0.2 pg C/μm 3 , Rocha & Duncan, ; ciliates = 0.19 pg C/μm 3 , Putt & Stoecker, ). Limnostrombidium viride , large form (50–60 × 50 μm), was the most common ciliate in our experimental bags, and this form is typical in Lake Baikal during summer (Obolkina, ).…”

“…Measurements of the respective laboratory cultures were used to estimate the added species' individual cell biovolume. Individual cell biovolumes of the resident species community were estimated according to Kremer et al (2014). Additionally, we categorized the community in three cell volume-size classes: nanoplankton (10-10 3 lm 3 ), microplankton (10 3 -10 6 lm 3 ), and mesoplankton (10 6 -10 9 lm 3 ) according to Ignatiades (2015).…”
