NASA's ABoVE dataset provides annual gray wolf denning spatial information, timing, and reproductive success across eight populations in western Canada and Alaska from 2000 to 2017. Data from 388 GPS-collared wolves were used to estimate 227 den initiation dates and pup survival, linked to seasonal climate metrics and NDVI-derived phenological indicators. This 18-year study captures interannual variability in wolf reproductive ecology within the Arctic-boreal region.
Antarctic sedimentary sequences from the past 50 million years provide a record of global climate influences on sea levels, atmospheric composition, and ocean circulation.
