Central to understanding animal ecology is how prey cope with the interacting risks of starvation and predation. This trade-off is modulated by the energy requirements of prey, yet relatively few studies have incorporated physiological mechanisms for energy savings when considering the behavioural response of prey to predation risk. In our study, we aimed to determine individual variation in behaviour,...
In seasonal climates, many animals, including a wide range of small mammals, are physiologically capable of prolonged dormancy (˜hibernation), when foraging‐related activity ceases entirely for part the year. Low metabolic rates while dormant minimise energy and water requirements, but the behavioural state of inactivity also reduces exposure to mortality risks, especially predation.

Aims Soil biota regulate essential ecosystem processes but our understanding of how soil fertility constrains biotic interactions remains limited. We investigated belowground responses to short-term phosphorus (P) fertilization in a P-limited woodland. Methods Ten Eucalyptus tereticornis were randomly selected and five fertilized with superphosphate equivalent to 50 kg P ha−1 over 6 months. We estimated...
