camilaI am interested in molecular genetic techniques that can be used to study the link between genotype and fitness in the Antarctic fur seal (Arctocephalus gazella). My Master thesis centres on hormonal analysis of mothers and their offspring from two adjacent colonies differing in high and low social density on Bird Island, South Georgia. I aim to investigate how social density affects stress by analysing cortisol levels in both mothers and pup pairs and how they differ between both colonies. I also intend to combine data on cortisol levels together with genotypic and behavioural data in order to search for a link to overall fitness.

Previous Research and Other Interests

For my bachelor thesis I worked in the department of Systematics, Biodiversity and Evolution of Plants at Georg-August University Göttingen. I focused on the facultative apomictic R. variabilis and investigated whether light, as abiotic stress, could favour sexual seed forming over asexual reproduction using molecular genetic tools.
