Future studies should estimate canopy turnover rates, which are affected by the balance between the recovery of gaps and repeated gap creation by black bears.
For relatively small genomes with limited numbers of sequence repeats, gaps between genomic sequences can be bridged by polymerase chain reaction or cloning strategies.
Although the repetitive sequences themselves are not tiled, the enrichment of unmethylated genome can assess methylation status of the repetitive sequences by probing the unique sequences flanking the repeats (gaps in the tiling microarrays) (Supplementary Material, Fig. S1B).
The process was repeated until all gaps were closed for each circular chromosome.
In the MP analysis, starting trees were obtained via random stepwise addition of taxa repeated 10 times, gaps were treated as "fifth base", and TBR was selected.
Program parameters were varied in repeated runs: CYNTENATOR gap and mismatch penalty parameters were set to 0.1, 0.5, 1, 2, 3, 5, 20, the alignment score threshold was set to 1, the minimal alignment length to 2, the maximal number of retained alignments to 1,000 and the gene coverage filter to 4. MCMuSeC was run to report gene clusters, which are shared by at least two genomes.
Yet the same question was being repeated, "Where is the gap, where is the gap?" When it came my time to speak on the youth panel, my response to the given prompt was simple: The gap is right here.
Penrose originally discovered the P1 tiling in this way, by decomposing a pentagon into six smaller pentagons (one half of a net of a dodecahedron) and five half-diamonds; he then observed that when he repeated this process the gaps between pentagons could all be filled by stars, diamonds, boats and other pentagons.
Thus, in line with increasing returns theory, an initial high investment into an existing institution generated incentives to perpetuate the institution's design, purpose, and influence, notwithstanding its acknowledged policy gaps and repeated calls for reform.
