- DOI：
- doi:10.5061/dryad.2hk46
- 摘要：
- s) population from western France, that exhibits 3-year cycles. Several overcompensating nonlinear models for populations dynamics are fitted to the data, notably

- 摘要：
- and accuracy, especially for the parameters of the detection function. SCR models estimated abundance with a low bias (< 10%) even at high degree of aggregation
Data from: Integrated species distribution models: combining presence-background data and site-occupany data with imperfect detection

- 摘要：
- a, with the predictive performance of the Integrated Model again found to be superior. PB models are known to produce biased estimates of species occupancy or abundance
Data from: Abundance estimation with sightability data: a Bayesian data augmentation approach
- 负责人：
- DOI：
- doi:10.5061/dryad.f8669
- 摘要：
- ose abundance in2006 and 2007 and the log rate of change between the two years. 3.Unlike traditional design-based estimators,model based estimators require
Data from: Predator-prey dynamics and the plasticity of predator body size
- 负责人：
- DOI：

- 摘要：
- y size variation through time. We tested the model with experimental data on body size and abundance dynamics in the Didinium-Paramecium predator-prey system. We use

- 摘要：
- s complicate comparison. Abundance of the Chukchi Sea subpopulation, derived by extrapolating density from the study area using a spatially-explicit habitat
Data from: False exclusion: a case to embed predator performance in classical population models

- 摘要：
- earities and threshold behaviours into dynamic models leading to unexpected outcomes: specifically, as prey abundance increases predators: 1) become less efficient at usi
Data from: Mixture modeling of transcript abundance classes in natural populations

- 摘要：
- fornia population. Using a mixture modeling approach, transcripts were identified that exhibit more than one mode of transcript abundance across the samples. Power
Data from: Models for assessing local-scale co-abundance of animal species while accounting for differential detectability and varied responses
- 负责人：
- DOI：
- doi:10.5061/dryad.fn208
- 摘要：
- We developed a new modeling framework to assess how the local abundance of one species influences the local abundance of a potential competitor
