- doi:10.5061/dryad.dd602
- 摘要：
- to test the effects of harvesting on the stocks and concentrations of soil C, N, and P and C:N:P ratios relative to uncut control stands. 3. With al
Data from: The influence of landscape context on short- and long-term forest change following a severe ice storm

- 摘要：
- the landscape context of forest stands influences plant community response to natural disturbances. 2. Using data from surveys of forested plots in the years immedi
Data from: Removal of cattle accelerates tropical dry forests succession in Northwestern Mexico

- 摘要：
- with and without cattle (chronic grazing or exclusion from grazing for ~8 yr). Forest stands were grouped into five successional stages, ranging from recently abandoned
Data from: Forest cover mediates genetic connectivity of northwestern cougars
- 负责人：
- DOI：
- doi:10.5061/dryad.3bn62
- 摘要：
- to estimate the landscape resistance between pairs of individuals based on rescaled GIS layers for forest canopy cover, elevation, human population density
Data from: Pollen flow in fragmented landscapes maintains genetic diversity following stand-replacing disturbance in a neotropical pioneer
- 负责人：
- DOI：
- doi:10.5061/dryad.n06g2
- 摘要：
- t the mating patterns of V. ferruginea are relatively robust to density differences between old growth and secondary forest stands. In addition, we observed that pollen
Data from: Ecosystem carbon density and allocation across a chronosequence of longleaf pine forests
- 负责人：
- DOI：
- doi:10.5061/dryad.760b3
- 摘要：
- e small fractions of ecosystem C in these frequently burned stands. Stand age and site index accounted for 76% of the variation in ecosystem C amo

- 摘要：
- allowed by remote-sensing like airborne light detection and ranging (R2=0.63, bias=35.1%, error=58.73). Using twenty-one 1-ha forest inventory plots, stand
Data from: The traits that predict the magnitude and spatial scale of forest bird responses to urbanization intensity
- 负责人：
- DOI：
- doi:10.5061/dryad.t4g871v
- 摘要：
- . An understanding of how species traits, as proxies for mechanisms, mediate the effects of urban intensification on forest species can help fill this knowledge gap
