- 摘要:
- of density. Thus, behavioural traits were characterized by limited ontogenic consistency, and natural selection was heterogeneous between density treatment
Data from: Territory size decreases minimally with increasing food abundance in stream salmonids: implications for population regulation

- 摘要:
- educing territory size will be inefficient; a 20-fold increase in food abundance would be required to double population density. Our analysis may also have implications

- 摘要:
- , but its entropy and the generating moments of heterogeneity are independent of density. This lack of influence of density on heterogeneity is neither due to low yea
Data from: Evolution of drug-tolerant nematode populations in response to density reduction

- 摘要:
- with Ivermectin; the magnitude of this increase varied with the intensity of selection and life-history stage. Our results suggest that interactions between density
Data from: Weighting effective number of species measures by abundance weakens detection of diversity responses

- 摘要:
- h diversity indices and species richness measures. However, it is not yet clear if ENS improves interpretation and comparison of biodiversi
Data from: Alongshore variation in barnacle populations is determined by surfzone hydrodynamics

- 摘要:
- was negatively related to solar radiation. Across the region, long-term mean wave height and an indicator of upwelling intensity and frequency did not explain

Data from: Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs

- 摘要:
- m function. Here, we test whether leaf traits consistently respond to experimental treatments across 27 globally distributed grassland sites across 4 continent
Data from: Compounded perturbations in coastal areas: contrasting responses to nutrient enrichment and the regime of storm-related disturbance depend

- doi:10.5061/dryad.kv5h0
- 摘要:
- 1.Natural systems are exposed to compounded perturbations, whose changes in temporal variance can be as important as those in mean intensity
Data from: Does local conspecific density and floral display size influence fruit set via pollinator visitation in Orchis militaris?

- 摘要:
- Plant density varies naturally, from isolated plants to clumped individuals, and can influence pollinator foraging behaviour and plant
