Strong genetic divergence was detected between Pacific colonies of Flesh-footed Shearwaters, relative to those further West. Molecular analysis of bycatch from the Sea of Japan suggests segregation of the non-breeding distribution based on telemetry may be invalid.
Geophysical features of sample sites were recorded in order to investigate their relationship with debris density. Results suggest the density of macro debris (items > 5 mm) is highest on uninhabited, sandy beaches facing a leeward direction
The highly organized morphogenesis of bird feathers holds important phylo- and ontogenetic information on the evolution of birds, organogenesis, tissue regeneration, and the health status of individual animals.
We collected basic biological information on Henderson Petrels, including nest success, and found that the extrapolated population size of 19 987 pairs in 2015 was marginally higher than the comparable estimate of 18 668 in 1991.
Here, we discuss and propose standardized techniques, approaches and metrics for reporting debris ingestion that are applicable to most large marine vertebrates. As a case study, we examine how the use of standardized methods to report ingested debris in Northern Fulmars
