Several bird species have advanced the timing of their spring migration in response to recent
climate change. European short-distance migrants, wintering in temperate areas, have …

Whole-genome sequencing projects are increasingly populating the tree of life and
characterizing biodiversity 1 , 2 , 3 – 4 . Sparse taxon sampling has previously been proposed to …

We conducted large-scale, systematic sampling of influenza type A virus in migratory waterfowl
(mostly mallards [Anas platyrhynchos]) at Ottenby Bird Observatory, southeast Sweden. …

Adaptive radiation plays a fundamental role in our understanding of the evolutionary process.
However, the concept has provoked strong and differing opinions concerning its definition …

Many bacteria have evolved ways to interact with glycosylation functions of the immune
system of their hosts. Streptococcus pyogenes [GAS (group A Streptococcus)] secretes the …

We studied long‐term trends and the yearly variation in mean spring passage time in 36
passerine bird species trapped at Ottenby Bird Observatory in south‐eastern Sweden. Between …

Neo-sex chromosomes often originate from sex chromosome–autosome fusions and
constitute an important basis for the study of gene degeneration and expression in a sex …

Climate change has been shown to shift the seasonal timing (ie phenology) and distribution
of species. The phenological effects of climate change on living organisms have often been …

Despite tremendous efforts in the past decades, relationships among main avian lineages
remain heavily debated without a clear resolution. Discrepancies have been attributed to …

A recurring feature of oceanic archipelagos is the presence of adaptive radiations that
generate endemic, species-rich clades that can offer outstanding insight into the links between …
