The paper uses time-lagged causal inference to show climate and anthropogenic factors reduce seabird breeding success and population size, with delayed recruitment effects contributing to declines.

This study uses path analysis to show that warmer winter ocean temperatures and organochlorine pollutants both affect the survival of great black-backed gulls through their impact on body mass.

This study uses whole genome analyses of Atlantic puffins to reveal complex population structure, identifying four genetically distinct clusters and a secondary contact zone, challenging current taxonomy.
