Thesis title: Making sense of a smelly situation: the effects of pollution on invertebrate memory and behaviour

Supervisors: Tanya LATTY , Clare MCARTHUR , Dieter HOCHULI

Thesis abstract:

Urban environments and the roads bisecting significantly increase the concentrations of harmful pollutants, including particulate matter and oxides of nitrogen. These pollutants are detrimental to human health and, can influence the physiology and development of flora and fauna. My research explores the effects of common air pollutants on invertebrate behaviour, with particular emphasis on invertebrate memory and cognitive ability. Using the European honey bee (Apis mellifera) as a model species, I investigate the effects of urban pollutants, including those associated with roads and vehicle exhaust, on the recognition and memory of floral-odours by honey bees.
