Synchronous timing of return to breeding sites in a long-distance migratory seabird with ocean-scale variation in migration schedules.

Background: Migratory birds generally have tightly scheduled annual cycles, in which delays can have carry-over effects on the timing of later events, ultimately impacting reproductive output. Whether temporal carry-over effects are more pronounced among migrations over larger distances, with tighter schedules, is a largely unexplored question.

Methods: We tracked individual Arctic Skuas Stercorarius parasiticus, a long-distance migratory seabird, from eight breeding populations between Greenland and Siberia using light-level geolocators.

Declining population trends of European mountain birds.

Mountain areas often hold special species communities, and they are high on the list of conservation concern. Global warming and changes in human land use, such as grazing pressure and afforestation, have been suggested to be major threats for biodiversity in the mountain areas, affecting species abundance and causing distribution shifts towards mountaintops. Population shifts towards poles and mountaintops have been documented in several areas, indicating that climate change is one of the key drivers of species' distribution changes.

Regulatory and policy barriers to effective clinical data exchange: lessons learned from MedsInfo-ED.

MedsInfo-ED is a proof-of-concept clinical data exchange project that uses prescription claims data to deliver patient medication history to emergency department clinicians at the point of care. This patient safety initiative, while limited in scope and scale, has been crucial in identifying numerous policy and regulatory barriers to successful clinical data exchange. The lessons learned and strategies to overcome the barriers are the focus of this paper.
