Background: The use of wild plants depends on a number of sociocultural and ecological factors, such as the ease of access to natural environments. This limitation for urban inhabitants leads to differences in the knowledge and use of wild plants compared to rural inhabitants. Hypothesis: Rural and urban populations tend to share a similar knowled...

Seed dispersal is a critical process for plant reproduction and regeneration. Successful recruitment depends on pre- and post-dispersal processes that complete a seed’s journey until becoming a new plant. However, anthropogenic stressors may disrupt the seed dispersal process at some stages, collapsing plant regeneration and hampering its long-term...

Exotic species are one of the main threats to biodiversity, leading to alterations in the structure and functioning of natural ecosystems. However, they can sometimes also provide ecological services, such as seed dispersal. Therefore, we assessed the ecological impacts of exotic species on native dispersal systems and the mechanisms underlying the...

Niche partitioning is a common strategy species use to avoid competition for limited resources, allowing them to coexist. Rodent species often reduce competition by spatial segregation and trophic differentiation, but behavioural differences, particularly related to foraging, can also be important. Therefore, temporal segregation can also be an imp...

Urban foraging practices are increasingly recognized as important components of metropolitan food systems, yet there are still knowledge gaps regarding the factors influencing wild edible plant use in urban contexts. Here, I examined the socio-ecological dynamics of wild edible plant use in the metropolitan area of Valparaíso, Chile. Through ethnob...

This database gathers 10,721 specimens, belonging to 2,578 species from the Chilean vascular flora (angiosperms, gymnosperms and pteridophytes) deposited in the Herbarium of the Pontificia Universidad Católica de Valparaíso (PUCV) in Chile. The PUCV botanical collection was started by the renowned botanist Otto Zöllner and represents a major natura...

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 visi...

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 p...

Usos tradicionales de 730 especies de plantas nativas de Chile.

Biodiversity loss is a central issue in conservation biology, with protected areas being the primary approach to stop biodiversity loss. However, education has been identified as an important factor in this regard. Based on a database of threatened species and socioeconomic features for 138 countries, we tested whether more protected areas or more...

Chenopodium giganteum D. Don is described as a new alien plant species in the Chilean vascular flora. A brief description, illustrations and an identification key for alien species of the genus Chenopodium L. present in Chile are provided.

The presence of Araujia sericifera Brot. (Apocynaceae) in the vascular flora of central Chile is reported for the first time. A morphological description and an illustration is provided, as well as a background about its habitat, ecology and phenology. | Primer registro de Araujia sericifera (Apocynaceae: Asclepiadoideae) para Chile, una nueva espe...

Esta guía de campo aborda los usos tradicionales de la flora silvestre comestible y medicinal de Chile y de otras partes del mundo. Además, aporta antecedentes sobre la distribución, hábitat y propagación de las especies tratadas.

Carduus tenuiflorus Curtis is described as a new alien plant species for Chile, whose introduction into the country is proposed around the year 1928. An identification key for species of the genus Carduus L. present in Chile is added.
