Research Background

Dr Rhian Guillem works at the Gibraltar Botanic Gardens as part of the Technical Team. Her background is in the biological sciences with a PhD in the chemotaxonomy of ants from the University of Sheffield. She is primarily an entomologist who specialises in the study of the taxonomy and faunistics of European and Mediterranean ants, in particular the myrmecofauna of Morocco and the area around the Strait of Gibraltar.

Her main research involves assessing the taxonomic status of Mediterranean ant species using surface chemistry (chemotaxonomy). She is also an active member of the Gibraltar Ornithological and Natural History Society (GONHS), working in the Invertebrates section.

Research Interests

Dr Rhian Guillem’s research interests are specialised in the taxonomy of Mediterranean ants. She is also working on cataloguing the Hymenoptera of Gibraltar. Rhian has contributed to over 24 scientific peer-reviewed research publications which have focused on ants, plants and birds.

She has produced notable research in the taxonomic status of ants, having produced papers identifying new species in different regions of Spain and documenting the species in Gibraltar and producing work on the behavioural traits of ant colonies. She also has contributed to projects involving the identification of all Lepidoptera species in Gibraltar and the ecology of bats, swifts and Crag Martins. Additionally, her work also focuses on identifying insect pest species, most specifically in Eucalyptus plants in Gibraltar.
