Survival of adult murres and kittiwakes in relation to forage fish abundance Survival of adult murres and kittiwakes in relation to forage fish abundance
Some seabird populations damaged by the Exxon Valdez oil spill continue to decline or are not recovering. In order to understand the ultimate cause of seabird population fluctuations, we must measure productivity, recruitment, and adult survival. Recent APEX studies focused on measuring productivity only. Recruitment measurement demands an unrealistic study duration. We propose to...

Migration of the Acadian Orogen and foreland basin across the Northern Appalachians of Maine and adjacent areas Migration of the Acadian Orogen and foreland basin across the Northern Appalachians of Maine and adjacent areas
The timing of Acadian orogenesis in Maine is reassessed, on the basis of a new Silurian-Devonian time scale, new U/Pb and 40Ar/39Ar ages of Acadian plutons, new conodont and palynomorph ages of strata that constrain the age of deformation, and published information. This analysis shows that the Acadian deformation front migrated some 240 km (present distance) from southeast to northwest...
