Data from: Do precipitation extremes drive growth and migration timing of a Pacific salmonid fish in Mediterranean?climate streams?

- 摘要:
- and in summer low?flow levels. We were surprised to find that differences in stream flows did not impact growth, body condition, or timing of out?migrati
Data from: Estimation of individual growth trajectories when repeated measures are missing

- 摘要:
- ) underestimate hidden individual heterogeneity when over 25% of repeated measures are missing. Here we demonstrate a flexible and robust way to model growth
Data from: Faster spring migration in northern wheatears is not explained by an endogenous seasonal difference in refueling rates
- 负责人:
- DOI:
- doi:10.5061/dryad.8c2k5
- 摘要:
- e is an endogenous seasonal difference in food intake and FDR, which could contribute to shorter stopovers and hence faster migration in spring. We measured daily
Data from: Do seaducks minimise the flightless period?: inter- and intra-specific comparisons of remigial moult

- 摘要:
- at the end of this period, thereby reducing wing-loading to increase flight capability. We studied timing of remigial moult, primary growth rates, flightlessness duration
Data from: Spatial and temporal variation in grazing damage by the gastropod Lacuna vincta in Nova Scotian kelp beds
- 负责人:
- DOI:
- doi:10.5061/dryad.ms6c2
- 摘要:
- with seasonal fluctuations in growth and physical properties of blade tissues. Grazing was largely concentrated in middle and distal sections, although this distributi
Data from: Climatic change only stimulated growth for trees under weak competition in central boreal forests

- 摘要:
- on, which was quantified using a modified Hegyi competition index. 3. We found that tree growth increased over time for trees under weak competiti
Data from: Thresholds and gradients in a semi-arid grassland: long-term grazing treatments induce slow, continuous and reversible vegetation change
