Data from: Territory size decreases minimally with increasing food abundance in stream salmonids: implications for population regulation
- 负责人：
- Grant, James
- 关键词：
- population density contiguous territories density limitation stream salmonids territoriality elastic disc model
- DOI：
- doi:10.5061/dryad.37hh4
- 摘要：
- How the local density of territorial animals responds to changes in food abundance will depend on the flexibility of territory size. Quantitative
Data from: Colony size affects breeding density, but not spatial distribution type, in a seabird

- 摘要：
- ross years, we find that inter-nest distances are smaller at higher local and overall breeding density, but that the spatial distribution type does not vary
