Sasha Vasconcelos
I'm interested in understanding how arthropods and their associated ecosystem services, particularly natural biocontrol, are affected by agricultural spread and intensification.

Research

Currently I'm a postdoc in the biodiversity and biocontrol lab at SLU, where I'm working with Miriam Karlsson and Mattias Jonsson to investigate how tomato fields in West and East Africa (Benin and Tanzania) can be managed to both enhance natural enemies and hinder the build-up of tomato pests. From among the communities of native natural enemies, we also aim to identify species with potential for augmentative biocontrol against the main lepidopteran pests of tomato in these regions.

Background

From 2017-2022 I conducted my PhD at CIBIO-InBIO (Portugal), in collaboration with the SLU Ecology Department. The focus of my thesis was to understand how arthropod diversity, abundance and community composition, as well as the potential for natural biocontrol, are influenced by the intensification of olive farming in the Euro-Mediterranean region.

Prior to this (2012-2016), I worked as a research fellow at CIBIO-InBIO and the former Lisbon Tropical Research Institute, conducting taxonomic revisions of Afrotropical butterfly collections. In parallel, I carried out research focused on the ecology and conservation of arthropods, with collaborations in projects examining the biodiversity impacts of cashew monoculture expansion in West Africa (Guinea-Bissau), and of EU afforestation schemes in Mediterranean open farmland (Portugal).
