Phytoplankton interactions as main focus of the 18th workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP)

an overview

Abstract

This paper aims to summarize the work, topics and contributions of the 18th Workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP), which took place in Natal, Rio Grande do Norte - Brazil, from August 27 to September 3, 2017. The Organizing committee was chaired by professors from two Brazilian universities at Natal and Sao Carlos and comprised scientists from Brazil and Argentina. In total, 39 scientific reports (5 plenary lectures, 20 oral presentations and 13 posters), prepared by 152 contributors from 20 countries were presented. The phytoplankton interactions were the main focus of the workshop, introduced in five plenary lectures. Most other presentations also dealt with this topic: they considered interactions among phytoplankters and phytoplankton-zooplankton interactions, but there was also an interest for processes involving mixotrophic organisms, phytoplankton-bacteria interactions, phytoplankton macrophytes interactions, parasitism and trophic webs. The factors influencing the phytoplankton development and diversity in different environments, as a background for phytoplankton interactions and drivers of phytoplankton diversity, were also discussed. Different aspects of the phytoplankton diversity were also presented with special emphasis on biodiversity conservation. Traditionally, methodological support for microscopic plankton counts and size measurements and trait-based approaches were among the side-topics of the workshop. Several future lines of research were suggested on the basis of the meeting summary.
