- 摘要：
- energetic expenditure, which could explain reported effects of geolocators on survival. We tested this ‘Energetic Expenditure Hypothesis’ in 12 populati
Data from: Costs of immunity and their role in the range expansion of the house sparrow in Kenya

- 摘要：
- . High investment in defenses should thus be disfavored. In the present study, we compared the energetic, nutritional and collateral damage costs

- 摘要：
- e. Miniaturized heart rate telemetry shows that they use a novel, cyclic, bradycardic state that reduces daily energetic expenditure by 10% and counter

- 摘要：
- costs are rarely measured. We know very little about the energetic resources required to maintain these traits at rest and the differ
Data from: The costs of a big brain: extreme encephalization results in higher energetic demand and reduced hypoxia tolerance in weakly electric
