Finally, we present an estimate of seed survival for those seeds that are finally retrieved to AG carton.
While highly speculative at this point, these assumptions provide the foundation for the only available estimate of seed success in the AG system, and all assumptions are designed to give an upper bound to the possible range of seed survival rates in P. macrostachya.
Therefore, seed germinability obtained in this way can be taken as the upper limit to the probability of seed germination and an estimate of seed viability.
In every instance this simple shuffling of the data completely abrogated detection of the enrichment signal, supporting the SBSE score as a robust estimate of seed enrichment in a differentially expressed dataset.
These scaled-up indirect estimates of trees' seed crops closely matched direct estimates from the census of fruit capsule production described above (r = 0.85; log-transformed values, r = 0.89, n = 25 trees), but were underestimated for trees with >40 capsules (points begin to fall below 1∶1 line).
Estimates of average seed dispersal distances in beech range between 17.7 m [ 7] and 21.6 m [ 16], which are surprisingly close to the average spatiogenetic separations found in our stands for the measure d0 of genetic difference.
Data on 861 maize seed lots from 606 households were used to estimate rates of seed replacement and diffusion.
Analytical results were used to estimate frequencies of seed lots containing transgenes at the regional and national level but not the frequencies of transgenes within seed lots.
Moreover, the r=−0.64 estimates of pollen vs. seed flow suggests that although seed dispersal is likely equivalent to pollen dispersal in A. germinans, in a patchy matrix, this seed dispersal still is usually very local, leading to greater biparental inbreeding, and increasing population genetic differentiation and spatial genetic structure in nuclear genomes [ 38, 39].
