- 摘要：
- e been overestimated for years, we also conducted a non-random point distance sampling survey according to macaque presence restricted to roads and trails. This survey

- 摘要：
- improves the accuracy of home-range estimates: with marine data, where the sampling schedule is highly irregular, with duty cycled data, where the sampling
Data from: Balancing sample accumulation and DNA degradation rates to optimize noninvasive genetic sampling of sympatric carnivores
- 负责人：
- DOI：
- doi:10.5061/dryad.23k27
- 摘要：
- success was ?70% through day 21 in winter, but declined to <50% by day 7 in summer. We identified a common temporal sampling frame of approximately 14
Data from: When do species-tree and concatenated estimates disagree? An empirical analysis with higher-level scincid lizard phylogeny
- 负责人：

- DOI：
- doi:10.5061/dryad.331jq
- 摘要：
- estimates had slightly lower support values when based on many more genes (44 vs. 10) and a small (?30%) reduction in taxon sampling. Thus, taxon sampling ma
Data from: On the variety of methods for calculating confidence intervals by bootstrapping

- 摘要：
- 1. Researchers often want to place a confidence interval around estimated parameter values calculated from a sample. This is commonly implemente

- 摘要：
- . 3. I employed hierarchical distance sampling along line transects to estimate N. m. mitchellii abundance at one site in lower Michigan, USA. This method requires
