“…In SPT, inhabitants speaking an original language were scarce (1.97 %), and there was a lower percentage of households lacking drainage and using charcoal and firewood as fuel in comparison with SAN (Table 1). Traditional SPT medicine has been enriched with introduced species that grow in home gardens, which guarantees immediate access (Cordero et al 2020). People from SPT employed almost the same percentage of introduced and native plants for medicinal use (48 vs. 52 %, respectively).…”

Background: Hot-cold conception is important for plant-disease relationships in peasant communities, where introduced species acquire medicinal uses and are more available in anthropocentric systems than native; how these are selected is studied with indices, hypotheses that contribute to theories are rarely tested. Hypotheses: There will be more medicinal introduced species that will have more versatility than native ones; home-gardens will have more availability of them than the forest. Study site and dates: San Pedro Topiltepec (SPT), San Andrés Nuxiño (SAN), Oaxaca, September 2015-March 2017. Methods: Medicinal flora and its uses were inventoried by community, recording availability (socioecological system) and status (native/introduced) by species. Informant consensus factor and relative value estimated information similarity among informants; use value (UV) indicated species versatility. Hot-cold conditions were recorded by species and disease. Results: Species and diseases were 64 (75 % native, 25 % introduced) and 134 in SAN, 81 (52 % native, 48 % introduced) and 177 in SPT, respectively. In SAN 58 % species were available in forests, in SPT 62 % species were available in home gardens. UV was higher for native plants in SAN and for introduced plants in SPT. Hot-cold dichotomy influenced selection of medicinal plants in both communities. Conclusions: Both communities belong the same ethnicity, select medicinal plants differently. SAN uses a higher proportion of native plants, forests have higher species availability, native plants are the most versatile. SPT uses similar proportions of native and introduced plants, home gardens have more availability, introduced plants are the most versatile.

“…Even today, many cultures worldwide still maintain the tradition of gathering wild plants due to their relevance to human survival and well-being ( Toledo et al 2009 , McCarter and Gavin 2015 ). However, despite its importance, traditional knowledge on the use of plants is progressively eroding due to several sociocultural and ecological processes, such as economic globalisation, cultural homogenisation and environmental degradation ( Cordero et al 2020b ). Nowadays, old traditions of plant gathering are being lost in most countries ( Łuczaj et al 2012 ); thus, it is crucial to increase efforts to safeguard traditional knowledge and preserve biological and cultural diversity for future generations ( Asfaw 2009 , Cordero et al 2020a ).…”

“…Although knowledge is acquired mainly through parents and community members ( Turreira-García et al 2015 ), other less traditional sources of information have also been identified. Online resources, such as digital books and websites, are essential for knowledge acquisition, especially in urban contexts, where interaction with nature is limited by multiple factors ( Cordero et al 2020b ). In a highly globalised world, easy access to ethnobotanical data through public websites is an alternative that has been scarcely explored, but could revitalise local identity and traditions ( Menendez-Baceta et al 2011 ).…”

We describe Rizoma, a new comprehensive online database on traditional uses of Chilean flora. The Rizoma database was built by reviewing multiple data sources on the uses of native plants and integrating phytogeographic and ecological aspects of plant species. This database attempts to safeguard traditional knowledge by making it available and visible to society, providing 1380 use records from 736 vascular plant species native to Chile. In addition, it contributes to a better understanding of the use patterns of Chilean native plants. The Rizoma database includes 1380 use records from 736 vascular plant species native to Chile, representing 399 genera and 128 families. Each species record provides information on geographic distribution, phytogeographic origin, life form, life span and use category. In addition, the online version includes information on the mode of use of each species, as well as common names and photographs. The database serves as a traditional knowledge repository that contributes to preserving local biological and cultural diversity for future generations.

“…Wild edible plants are an important component of urban floras (Díaz-Betancourt et al 1999). Wild edible plants are defined as species that grow spontaneously in self-sufficient populations in natural or disturbed ecosystems and can exist independently of direct human action (Heywood 1999, Cordero et al 2020). These species have been considered as a potential contributor to human diets (Guil-Guerrero et al 1998, Guil-Guerrero 2001, Penafiel et al 2011, Romojaro et al 2013, Turan et al 2003.…”

Will edible plants consider native and naturalized species (including weeds and ruderal plants), as well as domesticated species that scape cultivation and can grow without human interaction (Cordero et al 2020). Generally wild edible plants in urban areas are alien species (Díaz-Betancourt et al 1999, Ladio & Rapoport 2002, Tardío 2010, Turner et al 2011) that show tolerance to the stressful conditions imposed by urban environments.…”

Biodiversity-productivity relationship in urban vascular flora: a comparison between wild edible and non-edible plants

Background: Wild edible plants are species that are not cultivated but can be consumed as food. These plants may exhibit the highest taxonomic and phylogenetic diversity within urban floras, since they have a longer history of use associated with humans than non-edible plants. Also, because biodiversity is strongly associated with biomass, edible plants plant might show higher productivity (biomass per site) than non-edible plants. Questions: Is taxonomic and phylogenetic diversity of wild edible plants higher than non-edibles within urban areas? Is the alpha-biodiversity of wild edible plants positively related to biomass productivity in urban areas? Study sites and years of study: Cities of the coastal Mediterranean-type ecosystem, central Chile, 2015 and 2016. Methods: We characterized the taxonomic and phylogenetic diversity of urban flora differentiating wild edible and non-edible plants. Then, we assessed whether alpha-diversity of assemblages is related to their biomass productivity. Results: Both taxonomic and phylogenetic diversity were higher for edibles than non-edible plants. For edible plants, biomass was positively related to species richness and negatively with the mean phylogenetic diversity (MPD, a measure of evolutionary relationship among plants within an assemblage). Conclusions: Species richness is a suitable proxy to estimate wild edible plant diversity and their biomass in cities surpassing other proxies, such as phylogenetic diversity. Negative effect of MPD on biomass suggests that only a subgroup of related plants, possibly highly adapted to urban conditions, contribute to edible plant production. The distinction between wild edible and non-edible plants offers a better understanding of the assembly rules and biodiversity-biomass relationship within urban floras.
