Unearthing avian evolution: What can we learn from the skeletons of flightless birds?

Dr Peter Johnston researches the sensory adaptations of different species of flightless birds in the southern hemisphere, understanding how moa and elephant birds may have adapted to diurnal life

The evolution of flightless birds is a conundrum that scientists are still trying to solve. Using his experience in clinical medicine, Dr Peter Johnston from the University of Auckland, New Zealand, has recently unearthed new information about the sensory adaptations of several species of flightless birds, including the now extinct moa. This work demonstrates that, in contrast to previous hypotheses, […]

How natural disturbances sustain diversity

Natural disturbances like wildfires have a positive effect on species composition.

While natural disturbances like fires and floods can pose a risk to human life, in some places these events can help to support a diverse ecosystem. Forest fires, for example, allow species like oak to thrive and support a rich insect population, which in turn feeds many different birds. Dr Mike Eichholz of Southern Illinois University Carbondale studies the influence […]
