- 摘要：
- ) based on the random utility model. We performed a cost–benefit analysis to identify the optimal proportion of broad-leaved trees in conifer plantati
Data from: “Direct PCR” optimization yields a rapid, cost-effective, non-destructive, and efficient method for obtaining DNA barcodes without DNA extraction
- 负责人：
- DOI：
- doi:10.5061/dryad.4q4kf
- 摘要：
- ve PCR method that skips DNA extraction (“direct PCR”) and that can be used for a broad range of invertebrate taxa. We demonstrate how direct PCR can be optimized
Data from: Why cooperation is not running away
- 负责人：
- DOI：
- doi:10.5061/dryad.vt66f3m
- 摘要：
- . In this case, when the cost of changing partner tends toward zero, partner choice leads to the evolution of the socially optimum level of cooperation. This las

- 摘要：
- lizes dynamic programming methods to derive the optimal management decisions for the control of a theoretical insect pest population exposed to Bt crops. We consider three genotypes
Data from: Optimal foraging by herbivores maintains polymorphism in defence in a natural plant population

- 摘要：
- on that the total amount of invested resource can vary non-monotonically with set size. Finally, we show that it is sometimes optimal to encode
Data from: The combined effects of temporal autocorrelation and the costs of plasticity on the evolution of plasticity

- 摘要：
- ts and limiting factors simultaneously. Here we use a simulation model to investigate how the optimal level of plasticity in a population depends on a fixed fitness cost
Data from: Optimal soil carbon sampling designs to achieve cost-effectiveness: a case study in blue carbon ecosystems
- 负责人：
- DOI：
- doi:10.5061/dryad.qj472r2
- 摘要：
- methods for extrapolating C to 1 m soil depth. We found that 40 core samples are optimal for capturing C variance across 1000’s of kilometres but higher
