Alternatively, a multiple population model is also developed which simulates it's sequential counter part.
Multiple closed population models were evaluated, with Chao Mh ranking best in model performance and yielding a population estimate of 668 sharks with 95% confidence intervals ranging from 289 1720.
The multiple fibre population model, and probabilistic tractography approach employed in this study, may be able to cope with this better than deterministic approaches.
TESS runs were performed: (i) with a model that allows individuals to have ancestry in multiple populations (CAR model [ 80]); (ii) with correlated allele frequencies; and (iii) blinded to a priori population labels.
To our best knowledge, few papers deal with the existence of multiple periodic solutions for population models with harvesting terms on time scales.
However, most studies exploring the impact of ignoring spatial structure in stock assessments have developed population models with multiple subpopulations, rather than exploring the impact spatial dynamics may have on performance of non-spatially structured assessment methods.
Therefore, it is essential for us to investigate the existence of multiple positive periodic solutions for population models.
In contrast, nonparametric population models, having multiple discrete support points which describe the entire model parameter distributions without having to make any assumptions about their shape, can easily compute the expected weighted squared error with which any dosage regimen fails to hit a desired target and can then find the regimen which specifically minimizes that error.
Furthermore, the source code of the software is freely available to allow extensions to compute other summary statistics of interest (for example, the joint SFS of samples from multiple populations under generalized models, by extending the work of Wakeley and Hey 1997 and Chen 2012).
This study shows the utility of using matrix population models to combine multiple life history traits into a single estimate of the population growth rate when testing for genetic trade-offs between parasite resistance and lifetime fitness.
