Using field surveys, remote sensing and bioacoustics, my research aims at improving our understanding of the multi-trophic level consequences of climate warming in the arctic and sub-arctic ecosystems. Together with colleagues both at Lamont and at other institutions, I am currently exploring:
(1) The impact of climate warming and changing seasonality, on the interactions among vegetation, insects and songbird communities in an Arctic tundra ecosystem, on the North Slope of Alaska (field surveys, in situ remote sensing, bioacoustics) Project WebpageNew York Times Field Blog
(2) Understanding burn severity sensing in Arctic tundra: Exploring vegetation indices, sub-optimal assessment timing and the impact of increasing pixel size (field surveys, in situ and satellite remote sensing, bioacoustics)
(3) Use of remote sensing to study changes in biophysical structure associated with shifts in species dominance in Arctic tundra(field surveys, in situ remote sensing)
(4) Development of a remote sensing based method for short- and longer-term forecasting of reindeer pasture and caribou seasonal rangeland quality following tundra and taiga wildfire (field surveys, in situ and satellite remote sensing)
(5) What were the relationships between migratory songbirds, climate and shrub abundance in Arctic tundra ecosystems in the distant past (~LGM) to present?
