“…One of our findings was the high heterogeneity in the knowledge of medicinal plants. This finding is not different from the observed by several studies, which show that in medical systems knowledge is hardly shared among people, that is, most of the known plants is mentioned by one or a few persons (Barrett 1995;Hopkins & Stepp 2012;Santoro et al 2015), and a smaller group of species present shared and widespread knowledge. This high heterogeneity can be generated by some factors that we list below.…”

The role of kinship in knowledge about medicinal plants: evidence for context-dependent model-based biases in cultural transmission?

Th e similarity in traditional knowledge of medicinal plants was evaluated to draw inferences about the most important models for local knowledge transmission. Th e following questions were addressed: (1) Do related individuals possess greater similarity in knowledge of medicinal plants than unrelated individuals? (2) Do related individuals of the same generation possess greater similarity in knowledge than do related individuals of diff erent generations? Semistructured interviews were conducted on the medicinal plants known by the residents of a rural community in western Bahia. Mann-Whitney tests were used to compare Jaccard similarity values between related and unrelated individuals and between relatives of the same generation and relatives of diff erent generations. Related individuals were found to have more similar knowledge than unrelated individuals, and relatives of the same generation were found to have more similar knowledge than relatives of diff erent generations. Th ese fi ndings suggest that there are factors that favor cultural transmission between relatives of the same generation other than just vertical transmission.

We analyzed the botanical knowledge of the Laklãnõ-Xokleng people in the Ibirama Laklãnõ Indigenous Territory. Th ey are the last remnant of this ethnicity living in a unitary socio-political organization. Th e objective was to investigate the dynamics, distribution and transmission of botanical information. We interviewed 112 people in two villages about known and used plants. Data were collected through structured socioeconomic questionnaires, free lists and walk-in-the-woods tours. Data were analyzed using descriptive statistics and metrics of social network analysis. Of the 314 plants mentioned in the interviews, 77 % were currently used, 15 % were used in the past, and 8 % were known but never used. Men cited more plants than women. We found no correlation between the distribution of knowledge and age, but there was a relationship between families that valued Laklãnõ-Xokleng culture and individual knowledge. Transmission of knowledge about plants used medicinally and for handicrafts occurs mainly between generations and during childhood. Transmission networks emphasize the central position of elders as knowledge transmitters for their families. Diff erent network topologies refl ect particular dynamics in the medicinal and handicraft use of plants. External and internal pressures have caused changes in the transmission of the botanical knowledge of the Laklãnõ-Xokleng.

“…There is evidence in ethnobiological and ethnopharmacological studies that people share knowledge about a small set of species in a given local pharmacopeia. In other words, of the large group of medicinal plants familiar to a human group, only a small number of plants are known by the majority of people (Barrett 1995;Araújo et al 2012;Hopkins and Stepp 2012). Stated another way, knowledge about medicinal plants spreads heterogeneously, consistent with a ''consensus within diversity'' (see Barrett 1995).…”

Evidence shows that knowledge concerning medicinal plants is heterogeneous, as the majority of people in a medical system know only a few plants. This heterogeneity may make sense from an adaptive viewpoint, as human beings tend to keep a small set of information that offers adaptive advantages because our brains can store limited amounts of data. From this scenario, we developed the structural core concept for medical systems: a group of medicinal plants with adaptive characteristics that affect the structure and function of medical systems. We created a set of hypotheses based on the structural core concept to guide future studies investigating the structure and dynamics of local medical systems. Concerning the dynamics of medical systems, we suggest that the structural core is the part of the system that changes least over time, i.e., it is the most conservative. Thus, we can expect that species substitution events mainly occur outside of the structural core. From the medical system structure, we indicate that core plants tend to be favored in the transmission of knowledge. These plants also serve as a model for the selection of novel medicinal plants and are therefore an important factor for the medical system structure. Analysis of the structural core can help the understanding of the structure and dynamics of medical systems and can aid future bioprospecting studies, which can search for plants with pharmacological potential using the structural core.
