“…The five most quoted ones are Lamiaceae (29 taxa, 28.46% of UR), Asteraceae (54, 15.72%), Rosaceae (21, 10.67%), Apiaceae (15, 7.19%) and Lauraceae (one, 4.71%), the first three encompassing more than half of the total UR ( Figure 2 ). All but the last one are large or very large families, in terms of number of taxa, have a wide distribution, are among the most common in the Mediterranean region [ 52 ], and appear as leading families in most ethnobotanical prospections in this area, either regarding food or medicinal uses ([ 48 , 75 ] and references therein). In addition, all but the last one are among the five first families in the present work in number of taxa used.…”

“…This represents a total of 118,537 use reports (UR), of which 69,170 (58.35%) correspond to medicinal uses, 31,415 (26.50%) to food (including beverages) uses, and 17,952 (15.15%) to other uses. Several ethnofloristic or review papers focused on food plants have been published from this cultural area [ 13 , 44 , 45 , 46 ] as well as more general papers containing information on WFP [ 18 , 47 , 48 ] or dealing with reasons for the use of WFP [ 9 ], but to date no attempts to carry out a global or at least major analysis has been performed. Indeed, meta-analytical work on WFP in large areas is, as far as we can see, lacking elsewhere.…”

Wild food plants (WFP) have always been present in our kitchen, although they have not always been given the same importance as crops. In the Catalan linguistic area (CLA), covered in this paper, WFP were of great importance as a subsistence food not only during the years of the Spanish civil war (1936–1939) and World War II (1939–1945), but also long before these periods and in the years thereafter. The CLA has been well studied at the level of traditional knowledge on plant biodiversity, and much of this information is collected in a database by the EtnoBioFiC research group. The aim of this work is to carry out a meta-analysis of the WFP dataset of the CLA (only regarding edible uses, drinks excluded) and to identify the most quoted plants, and the information associated with them. With data from 1659 informants, we recorded 10,078 use reports of 291 taxa (278 of which at specific or subspecific levels and 13 only determined at generic level) belonging to 67 families. The most reported taxa, also with highest cultural importance indexes, are Thymus vulgaris, Foeniculum vulgare subsp. piperitum, Laurus nobilis, Rubus ulmifolius and Mentha spicata. The ethnobotanicity index for food plants is 6.62% and the informant consensus factor, also for food uses, is a very high 0.97, supporting the robustness of the information. The results provided and discussed in this work concern a significant part of the edible resources in the territory considered, which is, often and mainly, underestimated and underutilised. Its consideration could be an opportunity to promote closer and more sustainable agriculture. From the state-of-the-art of this question, it is possible to propose old, in some cases forgotten foods that could be newly introduced onto the market, first, but not only, at a local level, which could be interesting for new crop development in the frame of a valorisation of territorial identity.

“…Ingestion and deposition by livestock is not required for Prosopis seeds to germinate, but it improves seed germination, seedling performance and long-distance seed dispersal of this plant as it has a patchy distribution and no native vertebrate species have been found to disperse P. juliflora seeds in the Caatinga region. Seed dispersal by native ungulates (i.e., dears, Mazama americana Erxleben, 1777 and Mazama gouazoubira Fischer, 1814 (Artiodactyla: Cervidae)) is theoretically possible but large vertebrates have been intensively extirpated in the Caatinga region ( Bragagnolo et al, 2019 ; De Oliveira et al, 2019 ). Caatinga supports nearly 30 million cattle, goats and mules ( Sampaio & Costa, 2011 ; Santos et al, 2017 ) as a large number of active seed dispersers which spread through diverse habitat types, from old-growth forest stands to degraded areas ( Sampaio & Costa, 2011 ).…”

Background Biological invasion is one of the main threats to tropical biodiversity and ecosystem functioning. Prosopis juliflora (Sw) DC. (Fabales: Fabaceae: Caesalpinioideae) was introduced in the Caatinga dry forest of Northeast Brazil at early 1940s and successfully spread across the region. As other invasive species, it may benefit from the soils and seed dispersal by livestock. Here we examine how seed dispersal ecology and soil conditions collectively affect seed germination, early seedling performance and consequently the P. juliflora invasive potential. Methods Seed germination, early seedling survival, life expectancy and soil attributes were examined in 10 plots located across three habitats (flooding plain, alluvial terrace and plateau) into a human-modified landscape of the Caatinga dry forest (a total of 12,000 seeds). Seeds were exposed to four seed dispersal methods: deposition on the soil surface, burial in the soil, passed through cattle (Boss taurus) digestive tracts and mixed with cattle manure and passed through mule (Equus africanus asinus × Equus ferus caballus) digestive tracts and mixed with mule manure. Seeds and seedlings were monitored through a year and their performance examined with expectancy tables. Results Soils differed among habitats, particularly its nutrient availability, texture and water with finely-textured and more fertile soils in the flooding plain. Total seed germination was relatively low (14.5%), with the highest score among seeds buried in the flooding plain (47.4 ± 25.3%). Seed dispersal by cattle and mule also positively impacted seed germination. Early seedling survival rate of P. juliflora was dramatically reduced with few seedlings still alive elapsed a year. Survival rate was highest in the first 30 days and declined between 30 and 60 days with stabilization at 70 days after germination in all seed treatments and habitats. However, survival and life expectancy were higher in the flooding plain at 75 days and lower in the plateau. Prosopis juliflora seedling survival and life expectancy were higher in the case seeds were mixed with cattle manure. Synthesis Prosopis juliflora seeds and seedlings are sensitive to water stress and habitat desiccation. Therefore, they benefit from the humid soils often present across human-disturbed flooding plains. This plant also benefits from seed deposition/dispersal by livestock in these landscapes, since cattle manure represents a nutrient-rich and humid substrate for both seeds and seedlings. The quality of the seed dispersal service varies among livestock species, but this key mutualism between exotic species is due to the arillate, hard-coated and palatable seeds. Prosopis juliflora traits allow this species to take multiple benefits from human presence and thus operating as a human commensal.
