Global movement patterns of migratory birds illustrate their fascinating physical and
physiological abilities to cross continents and oceans. During their voyages, most birds land …

Using optimality perspectives is now regarded as an essential way of analysing and
understanding adaptations and behavioural strategies in bird migration. Optimization …

A comprehensive, systematic, analytically unified, and interdisciplinary treatment of energy
in nature and society, from solar radiation and photosynthesis to our fossil fuelled civilization …

The Flexible Phenotype attempts a true synthesis of physiology, behaviour, and ecology by
develo** an empirical argument that describes the intimate connections between …

Most populations of migrant shorebirds around the world are in serious decline, suggesting
that vital condition–dependent rates such as fecundity and annual survival are being …

Mountain ranges, deserts, ice fields and oceans generally act as barriers to the movement of
land-dependent animals, often profoundly sha** migration routes. We used satellite …

Unlike exercising mammals, migratory birds fuel very high intensity exercise (eg, flight) with
fatty acids delivered from the adipose tissue to the working muscles by the circulatory …

Abstract information processing between the brain and peripheral physiological systems. It
is suggested that, although several different pacing strategies can be used by athletes for …

A model is proposed in which the development of physical exhaustion is a relative rather
than an absolute event and the sensation of fatigue is the sensory representation of the …

Decades of research demonstrate that roads impact wildlife and suggest traffic noise as a
primary cause of population declines near roads. We created a “phantom road” using an …
