Sara Cristina Magalhães Carona

PhD Student

Sara Cristina Magalhães Carona is conducting a Ph.D. in Biodiversity, Genetics and Evolution (BIODIV) by the University of Lisbon starting in 2014 within Conservation Ecology and Evolutionary Genetics groups of cE3c. She is conducting the project “How do allopolyploid vertebrate complexes spatially structure their populations? The case-study of the Iberian fish Squalius alburnoides”, under the supervision of professor Filomena Magalhães (Conservation Ecology group) and professor Maria João Collares-Pereira (Evolutionary Genetics group).  Sara Carona Ph.D. project aims are: to quantify variation in the abundance of S. alburnoides genomotypes and their dependence on ecological factors, in the Sabor river basin; to assess interactions of genomotypes between each other and with the sympatric S. carolitertii, based on laboratorial experiments of trophic efficiency and agonistic behavior under variable conditions; to characterize the reproductive mechanisms and evaluate the influence of different crosses on the production and abundance of the genomotypes, based on the analysis of egg allocation, fertilization rate and offspring survival from experimental crosses. This study will be conducted in the frame of SABOR-LTER, using results as baselines for further testing hypothesis on the dynamics of the complex under increasing habitat fragmentation and altered climates, requiring long time series of ecological data.
