We used this hypothesis, introduced by Behrenfeld, as a principal model assumption and constructed a non-autonomous ordinary differential equation model for seasonally varying chl <jats:italic>a<\/jats:italic> concentrations. Our quantitative comparison between model simulations and <jats:italic>in situ<\/jats:italic> measurements of chl <jats:italic>a<\/jats:italic> and primary production collected from a Swedish fjord was 2-fold: first, using approximate Bayesian computations, we found distributions of values for the 3 model parameters that best described the chl <jats:italic>a<\/jats:italic> data. Then, we validated our model by comparing the simulated (not fitted) division rate to the division rate determined from the data. Our minimalistic model was able to capture (1) the yearly trend in the chl <jats:italic>a<\/jats:italic> concentration, (2) the pattern of growth and decline in the phytoplankton division rate, and (3) the decreasing trend in the relative change of the division rate exhibited in the data for several individual years. Moreover, the modeling efficiency was positive (between 0.3 and 0.9 with an average of 0.63) for all 11 yr included in this study. We conclude that the change in chl <jats:italic>a<\/jats:italic> concentration being proportional to the relative change in the division rate is a possible explanation for the bloom dynamics in the Gullmar fjord. In addition, our work provides a simple and empirically based differential equation for representing yearly dynamics of primary production, e.g. for generating ecological hypotheses using models of other trophic levels.<\/jats:p>","DOI":"10.3354\/meps13237","type":"journal-article","created":{"date-parts":[[2020,1,21]],"date-time":"2020-01-21T10:16:08Z","timestamp":1579601768000},"page":"63-77","source":"Crossref","is-referenced-by-count":0,"title":["Empirically based minimalistic model for representing seasonal phytoplankton dynamics"],"prefix":"10.3354","volume":"640","author":[{"given":"SH","family":"Piltz","sequence":"first","affiliation":[{"name":"National Institute of Aquatic Resources, Technical University of Denmark, Kemitorvet, Bygning 202, 2800 Kongens Lyngby, Denmark"},{"name":"Department of Applied Mathematics and Computer Science, Technical University of Denmark, Asmussens all\u00e9 Bygning 303B, 2800 Kongens Lyngby, Denmark"},{"name":"Department of Mathematics, University of Michigan, East Hall room 2074, 530 Church Street, Ann Arbor, Michigan 48109-1043, USA"}]},{"given":"PG","family":"Hjorth","sequence":"additional","affiliation":[{"name":"Department of Applied Mathematics and Computer Science, Technical University of Denmark, Asmussens all\u00e9 Bygning 303B, 2800 Kongens Lyngby, Denmark"}]},{"given":"\u00d8","family":"Varpe","sequence":"additional","affiliation":[{"name":"Department of Arctic Biology, University Centre in Svalbard, 9171 Longyearbyen, Norway"},{"name":"Akvaplan-niva, Fram Centre, 9296 Troms\u00f8, Norway"},{"name":"Department of Biological Sciences, University of Bergen, 5020 Bergen, Norway"}]}],"member":"1913","reference":[{"key":"Ref1","doi-asserted-by":"publisher","DOI":"10.1002\/2014GL061047"},{"key":"Ref2","doi-asserted-by":"publisher","DOI":"10.3354\/meps251001"},{"key":"Ref3","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-ecolsys-102209-144621"},{"key":"Ref4","doi-asserted-by":"publisher","DOI":"10.1093\/biomet\/asp052"},{"key":"Ref5","doi-asserted-by":"publisher","DOI":"10.1890\/09-1207.1"},{"key":"Ref6","doi-asserted-by":"publisher","DOI":"10.1038\/nclimate2349"},{"key":"Ref7","doi-asserted-by":"publisher","DOI":"10.1146\/annurev-marine-052913-021325"},{"key":"Ref8","doi-asserted-by":"publisher","DOI":"10.4319\/lo.1997.42.1.0001"},{"key":"Ref9","doi-asserted-by":"publisher","DOI":"10.1002\/gbc.20050"},{"key":"Ref10","doi-asserted-by":"publisher","DOI":"10.1029\/2010GL044174"},{"key":"Ref11","doi-asserted-by":"publisher","DOI":"10.1038\/35037500"},{"key":"Ref12","doi-asserted-by":"publisher","DOI":"10.1038\/nature02437"},{"key":"Ref13","doi-asserted-by":"publisher","DOI":"10.1111\/j.1461-0248.2004.00702.x"},{"key":"Ref14","doi-asserted-by":"publisher","DOI":"10.1038\/383495a0"},{"key":"Ref15","doi-asserted-by":"publisher","DOI":"10.1093\/icesjms\/24.3.455"},{"key":"Ref16","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.2009.0584"},{"key":"Ref17","doi-asserted-by":"publisher","DOI":"10.1038\/363024a0"},{"key":"Ref18","unstructured":"Evans GT, Parslow JS (1985) A model of annual plankton cycles.
