Data from: A conceptual framework for clutch size evolution in songbirds
- 负责人:
- DOI:
- doi:10.5061/dryad.8415f
- 摘要:
- energy expenditure per offspring. These consequences then determine how reproductive effort is partitioned among offspring, while reproductive effort evolves from

Data from: Sex-specific winter distribution in a sexually dimorphic shorebird is explained by resource partitioning
- 负责人:
- DOI:
- doi:10.5061/dryad.71ds5
- 摘要:
- energetic costs per unit of body mass over males, helping them to winter in the cold. However, as the sexes have rather different bill lengths, differences in sex

- DOI:
- doi:10.20350/digitalcsic/8502
- 摘要:
- s proved to be a useful technique to study animal behavior with little direct observation, and also an effective way to measure energy expenditure, allowing

Data from: Effects of increased flight on the energetics and life history of the butterfly Speyeria mormonia
- 负责人:
- DOI:
- doi:10.5061/dryad.ts705
- 摘要:
- Movement uses resources that may otherwise be allocated to somatic maintenance or reproduction. How does increased energy expenditure affect

Data from: The influence of wind selectivity on migratory behavioral strategies
- 负责人:
- McCabe, Jennifer
- DOI:
- doi:10.5061/dryad.60qm3
- 摘要:
- Air and water currents affect the timing and energy expenditure of many migratory animals, and therefore selection of favorable currents is importa

Data from: Directed flight and optimal airspeeds: homeward-bound gulls react flexibly to wind yet fly slower than predicted
- 负责人:
- DOI:
- doi:10.5061/dryad.7vs7r
- 摘要:
- and energy constraints. Airspeeds in goal-directed flight are predicted to approach or exceed maximum-range airspeeds, which minimize transport costs (energy expenditure

- DOI:
- doi:10.5061/dryad.ss548
- 摘要:
- -induced variation in costs versus supplies of energy, however, is uncertain, as is the degree to which such responses are mediated by current stores of energy

Data from: Long necks enhance and constrain foraging capacity in aquatic vertebrates
- 负责人:
- DOI:
- doi:10.5061/dryad.23vc1
- 摘要:
- cated that having the head on an extended neck would allow these cormorants to half the energy expenditure that they would expend if their body moved
