Data from: Bottom-up regulation of parasite population densities in freshwater ecosystems
- 负责人:
- DOI:
- doi:10.5061/dryad.427v8
- 摘要:
- te interactions. Empirical evidence that spatial variation in local host density drives parasite population density remains scarce, however. We test the coupling

Data from: Coral reef degradation is not correlated with local human population density
- 负责人:
- DOI:
- doi:10.5061/dryad.48r68
- 摘要:
- t coral reef degradation is not correlated with human population density. This suggests that local factors such as fishing and pollution are having minimal

Data from: Private land conservation has landscape-scale benefits for wildlife in agroecosystems

- 摘要:
- e of effect) and untangling density-dependent processes. We performed point counts over 6 years at 247 sites with similar local CREP density but varying

Data from: Does local conspecific density and floral display size influence fruit set via pollinator visitation in Orchis militaris?
- 负责人:
- DOI:
- doi:10.5061/dryad.3db38r1
- 摘要:
- , a high density being often associated with low fruit set in deceptive plants. In our study, we aimed to determine how local conspecific density

Data from: Can the source-sink hypothesis explain macrofaunal abundance patterns in the abyss? A modeling test
- 负责人:
- DOI:
- doi:10.5061/dryad.1s445
- 摘要:
- ts of the abyss. These low population densities may result in an Allee effect, whereby local reproductive success is inhibited, and populations are maintained

Data from: Differential influences of local subpopulations on regional diversity and differentiation for greater sage-grouse

- 摘要:
- of greater sage-grouse to parameterize a simulated approximate Bayesian computation (ABC) model and (i) test for regional differences in population density

Data from: Crossing the (Wallace) line: local abundance and distribution of mammals across biogeographic barriers

- 摘要:
- = 0.8: 1.4), but the local abundance of Malay civets (Viverra tangalunga), Rusa deer, and Sus pigs was similar in their native ranges and where they had been introduced by humans east

Data from: Density-dependent fitness, not dispersal movements, drives temporal variation in spatial genetic structure in dark-eyed juncos
- 负责人:
- DOI:
- doi:10.5061/dryad.85kc60b
- 摘要:
- e spatial genetic structure. Contrary to expectations, we found no effect of pre-dispersal density on dispersal distance or the proportion of locally-produced juveniles

- 摘要:
- Population density and individual dispersal behaviour affect species? distribution dynamics. Population densities vary over time, and some species

Data from: Highly diversified crop-livestock farming systems reshape wild bird communities

- 摘要:
- vegetables and fruits alone or integrated livestock into production. Crop-livestock systems harbored higher native bird density and richness relative to crop only farms
