We investigated whether cross‐cultural food plant selection in southern Africa is best explained by language ancestry, floristic environment or subsistence strategy.
Location
The flora of southern Africa region.
Taxa
All 1,740 edible plant taxa of southern Africa, representing 711 genera in 156 families.
Methods
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 pairwise distance matrices (language ancestry, geographical proximity, floristic and edible environments and utilized species) with Mantel tests using the ‘vegan’ package in R. Regression analyses were used to identify floristic and cultural preferences in food plant selection.
Results
Spatial autocorrelation did not influence the selection of edible plants by the 19 language groups of southern Africa (r = −.078). The floristic and edible environments had a strong correlation (r = .9743) while the distance matrices of the edible and actually utilized plants had a low correlation for 13 of the language groups (r = .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 |

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 < .001) with high R2 values (respectively .6181, .7702, .6654 and .7900), as were the relationship (p < .001) between what is edible and what was actually utilized. 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.
Main conclusions
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.</description><identifier>ISSN: 0305-0270</identifier><identifier>EISSN: 1365-2699</identifier><identifier>DOI: 10.1111/jbi.13743</identifier><language>eng</language><publisher>Oxford: Wiley Subscription Services, Inc</publisher><subject>Apocynaceae ; Arid regions ; Ascorbic acid ; Carbohydrates ; Coastal zone ; edible plants ; Fabaceae ; Flora ; Flora of southern African region ; Food ; Food plants ; Food preferences ; Food selection ; Galton's problem ; indigenous cultures ; Language ; Organs ; Regression analysis ; Storage organs ; subsistence strategy ; Taxa ; Traditional foods ; Underground storage ; underground storage organs ; Vegan ; Veganism</subject><ispartof>Journal of biogeography, 2020-03, Vol.47 (3), p.584-599</ispartof><rights>2019 John Wiley & Sons Ltd</rights><rights>Copyright © 2020 John Wiley & Sons Ltd</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c2973-efefe727a5d367ac2b816b776b8f0875038815e1a2107e789ccb116e97da5b5f3</citedby><cites>FETCH-LOGICAL-c2973-efefe727a5d367ac2b816b776b8f0875038815e1a2107e789ccb116e97da5b5f3</cites><orcidid>0000-0003-0306-8193 ; 0000-0003-2950-0001</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fjbi.13743$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fjbi.13743$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>315,781,785,1418,27925,27926,45575,45576</link.rule.ids></links><search><creatorcontrib>Welcome, Ashton K.</creatorcontrib><creatorcontrib>Van Wyk, Ben‐Erik</creatorcontrib><title>Spatial patterns, availability and cultural preferences for edible plants in southern Africa</title><title>Journal of biogeography</title><description>Aim
