DESCRIPTION:Amongst the sensory signals organisms send and receive\, chemi
 cal signals or ‘olfactory cues’ represent the oldest\, yet least inves
 tigated sense. In marine systems this ‘chemical language of life’ medi
 ates intra-and interspecific communication amongst most organisms\, for ma
 ny of which olfaction is the primary form of communication. In recent year
 s the impact of changing environmental conditions upon organisms’ abilit
 y to successfully utilise chemical signals has become an increasingly deba
 ted topic. Climate change associated stressors from temperature change to 
 increased pCO2 and with it in aquatic systems a reduction in water pH have
  been shown to alter animals’ responses to such ‘infochemicals’ lead
 ing to the phenomenon of ‘olfactory disruption’. Here I present our re
 cent work on marine invertebrates we use as model systems to understand th
 e mechanisms that underpin the observed behavioural changes\, and link the
 se to endpoints in order to evaluate potential impacts from individual to 
 ecosystem levels. Combining multiple stressors in a changing environment w
 e also evaluate the sub-lethal impacts of plastic derived odour compounds.
  Since the research group is involved in reach out linking to schools\, we
  show how climate change research is perceived by school children.
