Researchers tracked the movements of endangered caribou and sequenced a portion of their genomes to determine which genes may influence migratory behavior.
The Scientist spoke with the UK’s chief veterinary officer, Christine Middlemiss, about this winter’s high bird flu prevalence, the effects of the disease, and efforts to combat it.
The Scientist interviews evolutionary biologist Carles Vilà about how a large genomic inversion detected in common quail affects the birds’ physical characteristics and migratory behaviors.
A new study suggests that lighter colors may help these species stay cool on their long journeys, when birds are pushing themselves to their physiological limits.
A detailed analysis of cryptochrome 4 shows that the protein is highly sensitive to magnetic fields in vitro, but some researchers dispute the authors’ assertion that the findings could help explain avian magnetoreception.
The crania of individuals who lived in the Yucatán Peninsula during the late Pleistocene show a high degree of anatomical diversity among them, and their skull shapes differ from that of other North American populations of the time.
The decline in total occupied forest may not equate to an overall loss in butterfly numbers, but scientists are still concerned that their populations are suffering.
A museum sample of a 3,000-year-old Egyptian crop plant yields genomic information that helps researchers track the plant’s domestication and migration.
Modern-day populations in India descend from a mixture of peoples living thousands of years ago in South and Central Asia, including the Bronze-Age Indus Valley Civilization, two studies reveal.
