Data from: Friends and Family: a software program for identification of unrelated individuals from molecular marker data. And from: Genetic diversity, relatedness and inbreeding of ranched and fragmented Cape buffalo populations in southern Africa
The identification of related and unrelated individuals from molecular marker data is often difficult, particularly when no pedigree information is available and the data set is large. High levels of relatedness or inbreeding can influence genotype frequencies and thus genetic marker evaluation, as well as the accurate inference of hidden genetic structure. Identification of related and unrelated individuals is also important in breeding programmes, to inform decisions about breeding pairs and translocations. We present Friends and Family, a Windows executable program with a graphical user interface that identifies unrelated individuals from a pairwise relatedness matrix or table generated in programs such as COANCESTRY and GenAlEx. Friends and Family outputs a list of samples that are all unrelated to each other, based on a user-defined relatedness cut-off value. This unrelated data set can be used in downstream analyses, such as marker evaluation or inference of genetic structure. The results can be compared to that of the full data set to determine the effect related individuals have on the analyses. We demonstrate one of the applications of the program: how the removal of related individuals altered the Hardy-Weinberg equilibrium test outcome for microsatellite markers in an empirical data set. Friends and Family can be obtained from https://github.com/DeondeJager/Friends-and-Family.
Spatial patterns, availability and cultural preferences for edible plants in southern Africa
<p>Aim<br> We investigated whether cross-cultural food plant selection in southern Africa is best explained by language ancestry, floristic environment or subsistence strategy.<br> Location<br> The flora of southern Africa region.<br> Taxa<br> All 1740 edible plant taxa of southern Africa, representing 711 genera in 156 families.<br> Methods<br> Distribution data of plants were overlapped in ArcMap with 19 language maps, eight biomes and all taxa with nutritional data. Six correlations were estimated between five pair-wise distance matrices (language ancestry, geographical proximity, floristic and edible environments and utilised species) with Mantel tests using the 'vegan' package in R. Regression analyses were used to identify floristic and cultural preferences in food plant selection.<br> Results<br> Spatial autocorrelation did not influence the selection of edible plants by the 19 language groups of southern Africa (r = -0.078). The floristic and edible environments had a strong correlation (r = 0.9743) while the distance matrices of the edible and actually utilised plants had a low correlation for 13 of the language groups (r = 0.2174). Regression analyses between the floristic and edible environments for the FSA region and three languages, representing hunter-gatherers (Ju│'hoan), pastoralists (Khoekhoe) and agrarians (Venda) were all significant (p <0.001) with high R2 values (respectively 0.6181, 0.7702, 0.6654 and 0.7900), as were the relationship (p <0.001) between what is edible and what was actually utilised. Surprisingly, the Apocynaceae had a much higher residual value than globally important food plant families. Vitamin C of fruits seems to have higher levels along the coastal regions, and carbohydrates in underground storage organs have higher levels in the summer-arid western region.<br> Main conclusions<br> There is an apparent preference for certain food plant families in southern Africa. This selection appears to be driven by subsistence strategy, based on the categories of plants preferred by the three representative language groups.</p>
