The Patagonian steppe is a refuge for several indigenous peoples who live in relatively isolated communities, depending heavily on natural resources for their activities, health, and food security. The local ecological knowledge is a reservoir that generates full wellbeing and for which it must be the object of protection and local development. In this study, we aimed to find which factors can influence local ecological knowledge from a metacommunity on the Patagonian steppe.

- The study explores how exotic plants are introduced into local medical practices in Brazil, using the diversification hypothesis which suggests these species fill gaps in treatment options not covered by native plants.
- A systematic review of Brazilian medicinal plant studies up to 2011 revealed that while there is some overlap between native and exotic species in their therapeutic uses, exotic plants also address unique indications.
- The findings suggest two scenarios for the use of exotic species: they may either fill treatment gaps and expand their use over time or provide additional diversity and resilience in local medicinal systems alongside native species.
Article Synopsis
- This study focuses on the local ecological knowledge of edible plants with underground storage organs (USOs) among rural populations in North-Patagonia, aiming to understand usage patterns influenced by demographics like age, gender, and ethnicity.
- Semi-structured interviews were conducted with 51 locals, revealing that older individuals and those living with multiple generations use USOs more often, while Mapuche-identifying individuals utilize these plants the most frequently.
- The findings highlight the importance of wild plants in the Mapuche community for both historical sustenance and cultural identity, suggesting their potential in cultural revival and health promotion initiatives.
Article Synopsis
- The study investigates how medicinal plant knowledge changes in migrant communities, highlighting cultural evolution through interactions with native people.
- The research was conducted in Caeté-Açu, Brazil, comparing knowledge of medicinal plants among native residents, regional, national, and international migrants using free listing and interviews.
- Results indicated that while the total number of known plant species was similar across groups, differences existed in how knowledge was acquired, with natives learning primarily from their own community, whereas migrants sought knowledge from both natives and fellow migrants.
Resilience is related to the ability of a system to adjust to disturbances. The Utilitarian Redundancy Model has emerged as a tool for investigating the resilience of local medical systems. The model determines the use of species richness for the same therapeutic function as a facilitator of the maintenance of these systems.

To evaluate links between use frequency, ethnoecological knowledge, sociocultural variables and the conservation status of this plant.
Materials And Method: Forty informants were interviewed in relation to their knowledge, use, perception and the ecology of Oxalis adenophylla.
Ethnopharmacological Relevance: Although the relationship between local people and plants may be idiosyncratic, some human behaviors are common to different communities and can be influenced by cultural and environmental factors. Thus, this study drew upon a systematic review and meta-analysis to evaluate if there are patterns of medicinal plant use in different Brazilian ethnobotanical studies and if these patterns are influenced by the urbanization or ecosystems where the studies were conducted.
Materials And Methods: The factors evaluated concerned the origin of the species used (native vs.
Ethnopharmacological Relevance: The analysis of the influence of taxonomic affiliation on the selection of medicinal plants by Brazilian local populations can help elucidate theoretical aspects of medicinal plant selection.
Materials And Methods: Ethnobotanical medicinal plant studies were compiled and the resulting medicinal flora was compared to the total angiosperm flora with a Bayesian approach and the IDM model.
Results: A total of 35 families were considered to be overused and six were classified as underused for the Bayesian approach.
Ethnopharmacological Relevance: This study uses the utilitarian redundancy model as a basis to investigate issues related to the preference for plants native to the Caatinga used as anti-inflammatories by respondents from the community of Carão in rural Pernambuco, Brazil.
Materials And Methods: For this purpose, 49 respondents and 24 native plants used as anti-inflammatories were selected from a database built by previous studies in this study area. Interviews with respondents were conducted by applying the checklist-interview technique and by presenting photographs of plants, which were ordered according to plant preference for each type of inflammation mentioned.
