Data from: Biodiversity extinction thresholds are modulated by matrix type
- 负责人：
- DOI：
- doi:10.5061/dryad.37s4h
- 摘要：
- sity indices demonstrated abrupt declines, indicating that even higher-quality matrices cannot postpone diversity loss below this critical threshold. These results highlight

- 摘要：
- ) with removal experiments, we assessed how individuals' social network positions responded to the loss of their social associates. We found that the extent of flockmate loss

- DOI：
- doi:10.5061/dryad.26s85
- 摘要：
- historical samples demonstrated 15 previously unknown haplotypes and detected an extinct divergent clade. Through modelling, we estimated the loss of CR mtDNA

- 摘要：
- s an assessment of the HAZUS crop flood loss modeling methodology for Fremont County Iowa, specifically for heavy flooding that occurred there in June-August 2011
Data from: Stream nitrogen concentration, but not plant N-fixing capacity, modulates litter diversity effects on decomposition
- 负责人：
- DOI：
- doi:10.5061/dryad.1k7tr
- 摘要：
- was impaired at elevated water N concentration, possibly because a stoichiometric imbalance entails metabolic costs. 6. Our findings suggest that loss
Data from: Inferring skeletal production from time-averaged assemblages: skeletal loss pulls the timing of production pulses towards the moder

- DOI：
- doi:10.5061/dryad.rv0k6
- 摘要：
- a sea-level rise, rather than by a gradient in disintegration and sequestration rates, which remain constant with water depth; and (2) loss-corrected model-based
Data from: Surface and subsurface phosphorus discharge from a clay soil in a 9-year study comparing no-till and plowing
- 负责人：
- Uusitalo, Risto
- DOI：
- doi:10.5061/dryad.5bd4fs3
- 摘要：
- No-till as a water protection measure is highly efficient in controlling erosion and particulate phosphorus (PP) loss, but tends to increase
Data from: Where to forage when afraid: Does perceived risk impair use of the foodscape?

- Behaviorally Mediated Forage-Loss Hypothesis energy development forage use habitat selection human disturbance indirect habitat loss movement patterns mule deer perceived risk time-budgeting behavior
- DOI：
- doi:10.5061/dryad.cr90637
- 摘要：
- ly, avoidance of human disturbance prompted loss of otherwise available forage, resulting in indirect habitat loss that was 4.6-times greater than direct
Data from: Local biodiversity erosion in South Brazilian grasslands under moderate levels of landscape habitat loss

- 摘要：
- under the current rate of land use conversion, even at habitat losses below 50%. To avoid substantial biodiversity loss, conservation and more restrictive
Data from: Climate change surpasses land use change in the contracting range boundary of a winter-adapted mammal
- 负责人：
- DOI：
- doi:10.5061/dryad.nc637
- 摘要：
- The effects of climate change on biodiversity has emerged as a dominant theme in conservation biology, possibly eclipsing concern over habitat loss
