Data from: Influence of preexisting preference for color on sampling and tracking behavior in bumble bees
- 负责人:
- Maharaj, Gyanpriya
- DOI:
- doi:10.5061/dryad.21qb8m0
- 摘要:
- s. When maintained, we observed that other aspects of bee choice also reflected this bias, including increased sampling for the preferred color and an increased
Data from: Evaluating range-expansion models for calculating nonnative species’ expansion rate
- 负责人:
- DOI:
- doi:10.5061/dryad.ns624
- 摘要:
- range expansion rates may be heavily influenced by methodology and/or sampling bias. 2. We compared expansion rate estimates of Roesel’s bush-cricket (Metrioptera
Data from: A comparison of diversity estimators applied to a database of host-parasite associations

- 摘要:
- of biodiversity are limited by uneven sampling effort, with some regions or taxa better sampled than others. Numerous methods have been developed to account
Data from: Correction for bias in meta-analysis of little-replicated studies

- 摘要:
- t and meta-variance). 2. Small samples, typical of the ecological literature, induce big sampling errors in variance estimation, which substantially bias
Data from: Spatiotemporal sampling patterns in the 230 million year fossil record of terrestrial crocodylomorphs and their impact on diversity

- DOI:
- doi:10.5061/dryad.668950m
- 摘要:
- signal. Palaeotropical sampling is especially poor for most of the group's history. Spatiotemporal sampling bias impedes our understanding of seve
Data from: Breaking down the lithification bias: the effect of preferential sampling of larger specimens on the estimate of species richness
- 负责人:
- DOI:
- doi:10.5061/dryad.p85q4
- 摘要:
- the potential effects of preferential intersection that could also result in a methodologically related bias: the preferential sampling of larger specimens relative
Data from: How many more? Sample size determination in studies of morphological integration and evolvability
- 负责人:
- DOI:
- doi:10.5061/dryad.d0gm2
- 摘要:
- of the statistics of interest to sampling effort. We validate our equations using a dataset of cranial traits, and use them to make sample size recommendations
Data from: On the measurement of occupancy in ecology and paleontology
- 负责人:
- DOI:
- doi:10.5061/dryad.5sr24
- 摘要:
- e not found. The magnitude of this bias increases as the average occupancy probability decreases and as the number of sites sampled decreases. A maximum-likelihood method
Data from: The devil is in?the detail: estimating species richness, density, and?relative abundance of?tropical island herpetofauna

- 摘要:
- in sampling is poorly recognized, and it goes unnoticed especially in community ecology. By combining traditional open quadrats used for sampling forest floor
Data from: Reliable species distributions are obtainable with sparse, patchy and biased data by leveraging over species and data types
- 负责人:

- doi:10.5061/dryad.2226v8m
- 摘要:
- 1. New methods for species distribution models (SDMs) utilise presence?absence (PA) data to correct the sampling bias of presence?only (PO) data
