Juliana Stropp


Juliana is a tropical ecologist investigating biodiversity in the African and Amazonian rainforests. Her research explores how the environment shapes species distribution and how patchy sampling and species discoveries affect our understanding of biodiversity. She is currently at the MNCN-CSIC as MSCA-IF fellow, working on the project TAXON-TIME. In this project, she explores how the dynamics of species discoveries and taxonomic reclassifications impact established patterns of plant diversity and distribution.

Sergio Chozas

Former member

Sergio is a plant community ecologist working as postdoc in the Centre for Ecology, Evolution and Environmental Changes (cE3c) of the University of Lisbon, with broad interests in Plant community ecology. During his PhD, completed in 2016, Sergio studied the spatial and successional dynamics of xerophytic shrubs in SW Portugal dunes, co-supervised by Joaquín Hortal and Otília Correia. He is interested in the development of sustainable management strategies in cork and holm oak wood pastures (Montados/Dehesas), particularly conciliating conservation and maximizing ecosystem services. He is also involved in the use and development of citizen science as a tool for promoting citizen involvement in urban ecology and fighting plant blindness. Currently, he works at the project PORBIOTA, focused on the integration of existing biodiversity data aiming to provide services to the administration, the scientific community and society.
