The origin, distribution, and function of biological diversity are fundamental themes of
ecology and evolutionary biology. Research on birds has played a major role in the history …

Shearwaters and petrels (hereafter petrels) are highly adapted seabirds that occur across all
the world's oceans. Petrels are a threatened seabird group comprising 124 species. They …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Each year ecotoxicological problems become increasingly complex and encompass
broader spatial and temporal scales. Our practical understanding must evolve accordingly to …

Species are the fundamental units of biology, ecology and conservation, and progress in
these fields is therefore hampered by widespread taxonomic bias and uncertainty …

Across a range of organisms, related species or even populations of the same species
exhibit strikingly different scales and patterns of movement. A significant proportion of the …

Summary 1 We studied chick diet in a known‐age, sexed population of a long‐lived seabird,
the Brünnich's guillemot (Uria lomvia), over 15 years (N= 136; 1993–2007) and attached …

The importance of sympatric speciation–the evolution of reproductive isolation between
codistributed conspecific individuals–in generating biodiversity is highly controversial …

Migratory animals move up to thousands of kilometers every year [1]. Losses of migration (ie,
migratory drop-offs) occur when individuals of a migratory species stop migrating and …

Speciation—the multiplication of species through the evolution of barriers to reproduction
between populations—plays a central role in evolution since it enables two or more …
