Faced with warming summer temperatures across Alaska, white spruce tree growth in Interior Alaska has declined to record low levels, while the same species in Western Alaska is growing better than ever measured before.
University of Alaska Fairbanks scientists conducted two field studies to see if unmanned aerial vehicle cameras at various altitudes can take high-resolution photographs of beaches at low tide and hover above sea otters without disturbing them.
