- 关键词：
- Calibration Chinook salmon Convenience sample cross validation indices monitoring proxies weighted regression
- DOI：
- doi:10.5061/dryad.nk513
- 摘要：
- ues associated with a single level of abundance into a univariate index and then calibrated that index to mark-recapture estimates using several different te
Data from: Quantitative ornithology with a commercial marine radar: standard-target calibration, target detection and tracking, and measurement
- 负责人：
- DOI：
- doi:10.5061/dryad.45gb4
- 摘要：
- Marine surveillance radars are commonly used for radar ornithology, but they are rarely calibrated. This prevents them from measuring
Data from: The impact of fossil stratigraphic ranges on tip?calibration, and the accuracy and precision of divergence time estimates
- 负责人：
- DOI：
- doi:10.5061/dryad.7kh57t5
- 摘要：
- that the highest levels of accuracy and precision are achieved when fossil tips are calibrated based on the fossil occurrence from which
Data from: Fossils, molecules, divergence times, and the origin of Lissamphibians

- DOI：
- doi:10.5061/dryad.qt48h
- 摘要：
- taxa to be incorporated into a time-calibrated phylogeny with a user-defined geological time scale. The supertree incorporates 223 extinct species
Data from: How to survive a glaciation: the challenge of estimating biologically realistic potential distributions under freezing conditions
- 负责人：
- DOI：
- doi:10.5061/dryad.3bd5rr4
- 摘要：
- the effect of restricting the range of environmental conditions over which niche models are calibrated and then transferred to LGM conditions. We performed
Data from: Tree imbalance causes a bias in phylogenetic estimation of evolutionary timescales using heterochronous sequences
- 负责人：
- DOI：
- doi:10.5061/dryad.q4545
- 摘要：
- d the effect of tree imbalance on two empirical data sets: mitogenomes from primates and serial samples of the African swine fever virus. In analyses calibrated
Data from: A stochastic rate-calibrated method for time-scaling phylogenies of fossil taxa
- 负责人：
- DOI：
- doi:10.5061/dryad.vk7t0
- 摘要：
- time-scaling method must be calibrated with explicit estimates of three rates: branching, extinction and sampling, and thus is named the cal3 time

- doi:10.5061/dryad.5590q
- 摘要：
- a range of literature estimates for arthropods. We show that tribe-level analyses calibrated solely with the COI clock recover extremely old dates tha
Data from: Assessing cetacean surveys throughout the Mediterranean Sea: a gap analysis in environmental space
- 负责人：
- DOI：
- doi:10.5061/dryad.4pd33
- 摘要：
- , models calibrated on existing data may be used to predict species distributions in unsampled areas, given that available data are sufficient
Data from: The emergence of earliest angiosperms may be earlier than fossil evidence indicates
- 负责人：
- DOI：
- doi:10.5061/dryad.1rd0m
- 摘要：
- Gaps between molecular ages and fossils undermine the validity of time-calibrated molecular phylogenies. An example of the time gap surrounds the age
