Data from: Density-dependent energy use contributes to the self-thinning relationship of cohorts
- 负责人：

- 摘要：
- In resource-limited populations, an increase in average body size can occur only with a decline in abundance. This is known as self-thinning

- 摘要：
- t the two geographic populations from the Mogollon Rim were not genetically structured. A population size reduction was detected since the end of the last glacial period, which

- 摘要：
- . Our dataset was collected over 7 years (2005–2011) and included 2918 swallow captures and 1483 broods. Analyses revealed a substantial decline of the population

- 摘要：
- small population size, L. constancei faces heavy seed predation by small mammals. 2. As a stop-gap measure to prevent population decline, managers began covering
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
