MADELEINE TANDA: Maddie is interested in how environmental stressors such as ocean acidification and temperature change affect the structure of ecological communities, the traits of the component species, and the consequences of trait changes in affecting species interactions. She is exploring how traits vary in a core group of species (limpets) along environmental gradients,  She is also planning experiments that manipulate ocean acidification to explore how changing traits of marine species may shape the broader community through changes in habitat structure and ecosystem productivity, and has been exploring our long-term biological and environmental data series to test for signals of evolutionary responses in species interactions and their implications.
