Tracking a microscopic invader in South America: Ceratium furcoides

I am Victoria Accattatis, a PhD student from Santa Fe, Argentina (INALI, CONICET-UNL). This study focuses on the species Ceratium furcoides, an invasive dinoflagellate in South America. We performed the first study of this species in South America combining morphological, molecular, and phylogenetic information of natural populations from the Paraná fluvial system. This work is part of my doctoral fellowship which is based on studying the phylogeography, ecology and the processes involved in the dispersion of Ceratium. For this reason, we thank those who want to collaborate with samples or sequences of Ceratium spp. from different parts of the world. This will help us to analyze their phylogeographic patterns.

This study (*) is included in a more general overview in which we explore the effect of invasions on microbial communities (**), and the overall ecological processes that drive METAcommunities assembly (***).

This project thrives in an interdisciplinary environment led by Dra. Melina Devercelli and the collaboration of Dra. Paula Huber, Dr. Sebastian Metz, Dra. Claudia Piccini, Dra. Carla Kruk, and Dr. Angel Segura, and the financial support received by CONICET and Agencia Nacional de Promoción de la Investigación, el Desarrollo Tecnológico y la Innovación.

Any contact can be through my mail: vicky.accattatis -at- Thank you!
