Another popular show on Fox Sports 1, Speak for Yourself is an opinion-based studio program that covers all the latest updates in the NBA and NFL. Join the FOX NFL Sunday guys as they discuss whether or not we jumped on the Arizona Cardinals bandwagon a year too soon, how far the New York Giants' new culture can take them, what happened to the Denver Broncos with zero quarterbacks on the roster, and much more! 20. Arizona Cardinals: Zack Martin, OT, Notre Dame: A big boy who could play either tackle or guard, Martin started a school-record 52 games for the Fighting Irish over the course of four years. More rigorous methods such as distance-based redundancy analysis (Legendre & Anderson, 1999), multiple regression of distance matrices (Holzhauer et al., 2006), distance-based Moran’s eigenvector maps (Legendre & Legendre, 2012), or mixed effects models fit with an appropriate error structure (Clarke, Rothery & Raybould, 2002) should preferentially be used over Mantel tests in future studies seeking to estimate the effects of landscape features on genetic differentiation. Figure 4: Observed heterozygosity and allelic richness, averaged over all populations. Finally, we predicted that the removal of siblings from the data set would significantly alter population and landscape genetic estimates by increasing average allelic richness and heterozygosity within a sampled population, as well as increasing the average genetic differentiation among populations.



For example, numerous studies have assessed the role of inbreeding and heterozygosity on individual fitness (e.g., Balloux, Amos & Coulson, 2004; Ficetola et al., 2011; Harrison et al., 2011; Slate et al., 2004). Both of these population genetic attributes are particularly relevant in species of conservation concern, which often exist in small or isolated populations.

When comparing each life stage at each summary metric, we found no significant differences between data containing the sibling pairs and live football match now data with removed sibling pairs (permutation t-test P-value ≥ 0.19; Fig. 2, Tables 1 and 2). We found that the mixing of life stages resulted in genetic estimates of Ar, Ho, FST, and DC that, on average, did not differ from estimates made for each specific life stage (Tables 1 and 2). There were, however, up to three pond-pair FST values that fell outside of the bootstrapped 95% confidence intervals (Table 3). When genetic distance was measured using DC, only one pond-pair fell outside of the bootstrapped confidence interval. Given the interaction between selection pressures and genetic diversity, it is not unreasonable to believe that population genetic measures may differ depending on the age or life stage of the sampled cohort.



Contrary to our predictions, we did not observe significant biases in our population genetic measures among life stages or with the exclusion of full siblings from the data. To date, only Goldberg & Waits (2010) have empirically tested the effects of sampling different life stages in amphibians (one frog and one salamander species) and quantified the importance of removing full siblings prior to analysis. As in the analysis of mixed-tissue samples, the greatest differences were observed in relation to genetic differentiation measured by FST, which increased (insignificantly) after the removal of full siblings from the data, as well as from adults to embryos, to larvae. Dahlberg MD. 1979. A review of survival rates of fish eggs and larvae in relation to impact assessments. In our dataset, the IBD relationship, when assessed with DC, remained significant until the frequency of larvae and embryos in the population sample exceeded 60%. However, our power to detect a significant IBD relationship was substantially affected by the number of microsatellites used.



The IBD relationship was strongest when genetic distance was measured using DC, and we found that the IBD relationship seen in adult-only samples decreased as the proportion of larvae and embryos included in the population sample increased. Average rarefied allelic richness of adults was 3.83 (±0.22), 3.95 (±0.23) for embryos, and 4.13 (±0.20) for larvae. 0.053, Fig. 2F), with a greater proportion of field-collected samples being omitted from larvae. However, this trend was not observed when genetic distance was measured using allele frequencies (DC, Fig. 2D). Values of population genetic summary statistics calculated on data sets with siblings removed are given as the mean (±standard deviation). Our assessment of increasing the proportion of larval or embryo tissue samples clearly demonstrated that the calculated Mantel r decreases as the proportion of larval and embryo samples increases (Fig. 3). This pattern was consistent regardless of whether genetic distance was measured using FST or DC. Guillot G, Rousset F. 2013. Dismantling the Mantel tests. In our study, we assessed IBD through the use of simple Mantel tests.
