Beyond the hundred or so species of termites that are considered structural and agricultural pests, there are over 3,000 species performing crucial ecological roles as decomposers. This is especially prominent in tropical rainforests, where termite diversity is highest, and tropical savannas, where they account for the majority of wood decomposition. Yet despite their incredible diversity and biomass, the environmental factors influencing these patterns of community structure remain poorly understood. In this talk, I will focus on soil nutrients, and sodium in particular. As detritivores, termites have sodium needs that are orders of magnitude greater than is found in the plant material they consume. My work in the forest-savanna mosaics in the Republic of the Congo looks at the association between termite communities and natural salt licks called bais – a source of sodium scattered throughout the landscape – and the implications for decomposition rates.

North to Alaska: from NextGen sequencing to Citizen Science aiming to understand the subarctic and Arctic biodiversity

Scientists estimate that there are over 7.5 million species of plants and animals that have yet to be discovered and described. But in a world where extinction may outpace discovery, and global changes are occurring at a faster rate in Arctic and subarctic regions, like Alaska, how can citizen scientists get involved? Join me as I share how residents in Alaska helped me discover and describe a new species of snakeworm gnat (Diptera) and how I used DNA barcoding  (nanopore sequencing technology) to find 50 new species of Phoridae (Diptera).
