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:
- contiguous territories density limitation population density stream salmonids territoriality elastic disc model
- DOI:
- doi:10.5061/dryad.37hh4
- 摘要:
- ;Stream salmonids are an ideal model system for investigating flexibility in territory size, because food abundance can be quantified in the field
Data from: Resident species with larger size metrics do not recruit more offspring from the seed bank in old-field meadow vegetation

- 摘要:
- hypothesis to include two additional size metrics: leaf size and seed size. Specifically, we ask, for resident species within a crowded old-field meadow

- 摘要:
- : the size at initial assessment (by the first fire fighters to arrive at the scene) and the size at "being held" (a state when no further increase in size

- 摘要:
- ) and four compositions of boldness (all bold, all shy, mixed bold and shy, or average individuals) in the field and then measured their collective behaviour. Larger
Data from: Establishment of wildflower fields in poor quality landscapes enhances micro-parasite prevalence in wild bumble bees
- 负责人:
- DOI:
- doi:10.5061/dryad.4kb762c
- 摘要:
- wildflower fields on micro-parasite prevalence is affected by the composition of the surrounding landscape and the size of the flower field. The prevalence

- 摘要:
- . Our group monitored the body size of one Swiss Yellow Dung Fly (Scathophaga stercoraria; Diptera: Scathophagidae) field population over 15 years, including

- Tseng, Michelle
- DOI:
- doi:10.5061/dryad.5164v
- 摘要:
- . Laboratory data from broad taxonomic groups suggest that a widespread response to a warming world may be an overall decrease in organism body size. Howeve
