Drawing from ethnobotanical data from the Maira Valley (1970, 2022), Stura Valley (2004), and Grana Valley (2011), we explore dynamics in plant use and how they may have been generated by ecological, socio-economic, and cultural changes. A total of 308 plant taxa were recorded, with notable declines in Asteraceae and Lamiaceae utilizations by 2022, suggesting a remarkable erosion of traditional ecological knowledge (TEK). Conversely, the use of families like Brassicaceae and Amaranthaceae increased, possibly due to socio-economic factors. This study also found in recent years a decrease in medicinal plant uses and a greater reliance on food system-related plants. Logistic regression models highlighted altitude (600-1600 masl) as a key factor in plant diversity use, with older participants showing more diverse ethnobotanical knowledge. This study underscores the resilience and transformation of plant knowledge in response to socio-economic and environmental changes in the Alpine area.

In the study area, the language shift towards the lingua franca among the smaller ethnic groups (Decker, 1992) has primarily been triggered by a cultural adaptation towards the dominant cultures, possibly enhanced by frequent social exchanges and intermarriages. Research conducted in different parts of the Hindukush range has shown that the local ecological knowledge (LEK) associated with linked to wild food plants (WFP) among minority groups is being impacted as minority groups adopt dominant practices leading to the loss of their eco-cultural identities, or what we refer to as "ecocultural homogenization" (Aziz et al., 2020a(Aziz et al., , b, 2022a)). It is important to note that ecology has an important role in shaping local cultural practices (Milstein & Castro-Sotomayor, 2020). Studies have shown that for the last three decades the cultural landscape of the Chitral region, as well as its natural resource management, has undergone significant transformations , and we presume that these changes have not only affected local ecological

Despite their centuries-long presence across European countries, the Romani community's culinary and herbal practices have often been overlooked. A preliminary study on Romani domestic food and home (plant) remedies was conducted via 106 interviews in Turin, Rome, and Naples during the past fifteen years among urban Romani community members (who migrated to Italy from Romania and Serbia approximately three decades ago). By examining Romani's local food knowledge systems, this research highlights the importance of food ritual practices for preserving identity, fostering resilience, and bridging cultural divides; however, the data also show the plastic adaptability of Romani practices. Most quoted herbal items overlap the ones of the Balkan cultures where they lived together for centuries (Romanians and Serbs). The presented preliminary data insights into how the Romani diaspora in Italy has navigated cultural, economic, and social challenges through sophisticated mimicry and constant adaptation to new environments and cultures. Further understanding the Romani food ecological perceptions and ethnobotanical knowledge may be essential for improving social cohesion, challenging stereotypes, recognising the community's valuable contributions to European cultural diversity and, in general, building a more inclusive ethnobiology.

Our study aims to assess the change in plant usage, species diversity, and the changing roles of plants in local traditions in the western Alpine mountain ecosystems. While the 1983 survey documented medicinal uses centered around pastoralist practices, the 2024 data highlight a notable increase in the use of synanthropic plants, now utilized both medicinally and as food. Several species such as Allium sativum, Artemisia absinthium, and Urtica dioica have shown resilience and continuity in local cultural practices, maintaining medicinal, culinary, and ritual significance across the four decades. The 1983 survey documented the greatest variety of species ( ), a number that decreased in subsequent studies. The 2009 survey identified 36 species not previously recorded in 1983, and the 2024 field study noted an additional 20 species. The study highlights the economic potential of several wild species in these alpine areas, such as Achillea, Artemisia, Verbascum, Veronica, Viola, Polygonum, Bunium, and Sorbus spp., which could be utilized for creating new herbal teas, artisanal beers, liqueurs, ice creams, sweets, and seasoned food products. Expanding the uses of these plants could not only preserve ethnobotanical knowledge but also stimulate local economies and support sustainable development in alpine communities. The documented temporal shifts in plant usage reflect broader cultural, ecological, and socio-economic changes, underscoring the importance of preserving biodiversity and traditional knowledge amidst ongoing environmental and societal shifts. This study underlines the need to conserve ethnobotanical heritage while adapting to the evolving landscape of the region. Future research could focus on exploring the role of these species in broader sustainability initiatives, including conservation strategies, ecosystem services, and community-based tourism while continuing to document the cultural dynamics influencing plant usage.

Our present study aims to document the leafy, wild-sourced plant portion of the MD in the unique and isolated matrifocal community of Olympos, North Karpathos Isle, Greece. Methods An ethnobotanical field study focussing on traditionally wild-sourced edible greens (chórta) was conducted during the spring of 2023 via 42 semi-structured interviews with local people. Our study documented 69 wild green taxa, along with their culinary uses and linguistic labels. Half of the gathered wild greens have a bitter taste (i.e. members of Asteraceae and Brassicaceae), while 70% of the topquoted greens are bitter. These greens were mostly consumed cooked. Nearly half of the quoted taxa had been previously recorded as used in the food system of central Crete. In contrast, one-fourth of the folk phytonyms recorded in Olympos do not match the ones found in Crete and the rest of Greece, which may be linked to the Doric culture that the community remained attached to because of its isolation. However, the plant-human interaction kernel is similar to that of surrounding areas. Moreover, the community of Olympos seems to rely less on aromatic wild greens (compared with Crete). Cross-cultural foraging comparison is crucial for better understanding the circulation, exchange, and evolution of local plant knowledge under the MD umbrella. Our study assesses, in particular, how noteworthy phytolinguistic differences indicating different ancient trajectories of cultural encounters/exchanges may not necessarily be reflected in differences in terms of plant reports. As often postulated in linguistic ethnobiology, ancient linguistic labels sometimes remain as "empty shells". Given the fragile environment and the increasing over-tourism during the summer months the study site is experiencing, the presented data could contribute to a more substantial shift towards sustainable eco-tourism initiatives involving the foraging and cooking of wild greens.

This study investigates local ecological knowledge (LEK) linked to traditional gathering and consumption of WGs in the Lasithi Plateau of eastern Crete, where human genetic studies one decade ago showed very peculiar patterns, hypothesising that the Minoan civilisation took refuge there before it disappeared. A field ethnobotanical study was conducted to document the diversity of WGs and their detailed local culinary uses in the Lasithi area by interviewing 31 study participants. Fifty-nine folk taxa (species and subspecies) were recorded, corresponding to fifty-eight botanical taxa. A quotation index was measured to assess the cultural significance of WGs in the study areas; logistic regression analysis was adopted to understand the impact of sensory classifications of WGs and their local cooking methods. Lasithi's foraging showed a notable prevalence of bitter-tasting WGs, which play a central role in local cognition and culinary practices. This bitterness aspect of WGs, potentially influenced by cultural preferences and genetic factors, probably suggests a connection to the ancient Lasithi's inhabitants, i.e., Minoan dietary habits. We found that bitterness is the predominant sensory attribute in Lasithi, characterising 45.76% of the WGs. These findings underscore the complex interplay between local ecologies and biodiversity, LEK, and dietary traditions, highlighting the importance of WGs in understanding the evolution of foraging and plant culinary diversities across the Mediterranean.

The Pashtuns of the Marwat tribe in NW Pakistan are renowned for their traditional customs and food systems. Studying the wild food plants (WFPs) and their associated bio-cultural diversity is quintessential for fostering food security and sovereignty in the region. The research presented here investigated the area's wild food plants traditionally gathered and consumed. The field survey was conducted in 2023 with 87 study participants. A total of 41 plant species belonging to 24 botanical families was documented. The findings include food uses for Atriplex tatarica, Amaranthus graecizans, and Beta vulgaris subsp. maritima that have rarely been recorded in Pakistan. Moreover, the use of Citrulus colocynthus fruits in jam and Zygophyllum indicum leaves and stems in beverages are novel contributions to the gastronomy of NW Pakistan. The comparison with other food ethnobotanical studies conducted in North Pakistan suggests some similarities between the Lakki Marwat traditional WFPs and those from other semi-arid areas in North Pakistan, both Pashtun and non-Pashtun. While the findings underline the significant role of WFPs in local cuisine, we observed that this local knowledge is also threatened: the rapid spread of fast and industrialized food, modernization, and cultural dilution has led to an alarming reduction in these practices among the younger generations. Therefore, suitable measures to safeguard traditional plants, food knowledge, practices, and the associated culture are urgently needed. The urgency of this situation cannot be overstated, and it is crucial that we act now. Furthermore, preserving wild food plant-related cultural heritage may be fundamental to promoting food security and public health.

This study explores the women's knowledge (specifically from the Khowar (Kho) and Wakhi linguistic groups) of local food systems and determines their role in ensuring household food security and sustainability in the mountain regions of northern Pakistan. Based on in-depth semi-structured interviews with female informants in the Rech and Broghil valleys of upper Chitral, 91 different types of food products were recorded, including wild and cultivated species. Eremurus stenophyllus and Allium barsczewskii were the commonly utilized plant species, though distinct preferences between the Kho and Wakhi groups were noted. Prominent differences were perceived in using certain cultivated plants among the two ethnic groups. For instance, Kho preferred plants like Beta vulgaris, Zea mays, and Brassica napus as indicated by the use reports, while Wakhi concentrated on Thymus serpyllum, Zygophyllum obliquum and Papaver involucratum. Both groups had shared dairy practices, but cottage cheese and curd were highly cited among Kho, while double-fermented curd and Qurut for Wakhi. The study recorded some new food uses for specific plants, such as Atriplex hortensis, Carthamus tinctorius, Hylotelephium spp., and Saxifraga sibirica. Cross-culture analyses revealed a mosaic pattern of homogenous and heterogenous trends based on reported food species of plants/animals and their use reports. Our findings emphasize the significant role of women in sustaining local food diversity, food sustainability, and the preservation and security of the local food systems, cultural legacy, and household food management. Therefore, inclusive research addressing their social, economic, and environmental issues must be conducted. Furthermore, policies must incorporate women's traditional knowledge to build resilient food systems.

Despite this growing trend of nature exploration, few scholars have investigated the contribution of this new mode of engagement to human-nature connection and pro-environmental attitudes. Therefore, this research aims to explore the societal role of such foraging educators. Through convenience and snowball sampling, we recruited 31 foraging educators across Europe. Through semi-structured interviews, we inquired about their sources of knowledge, modalities of transmission and their roles as educators. The interviews revealed individuals who convey ethnobotanical knowledge to improve human-nature connection through experiences within nature. The educators gained their knowledge through written sources, vertical and horizontal sharing. Finally, foraging educators consider themselves social bridges of ecological knowledge, bringing scientific ethnobotanical information to a varied audience in an experiential way. Foraging stimulates the sharing of ecological knowledge, and it could be seen as a broader agroecological practice, enhancing the benefits of nature's contribution to people. There is great potential for emerging environmental education platforms and, correspondingly, for rethinking the food system.

To understand the dynamics of food preferences, cross-cultural studies on food plants should be conducted across diverse ethnic groups in a given area. In this context, the current study investigated the use of WFPs by seven different cultural groups in the Kashmir Himalayan Region. In this area, people gather wild plants and their parts for direct consumption, traditional foods, or sale in local markets. Despite this reliance, documentation of the food system, especially concerning WFPs, is notably lacking. Hence, our research aimed to document WFPs, along with associated traditional ecological knowledge, and identify major threats to their long-term sustainability in Division Muzaffarabad. Methods Through a comprehensive approach involving questionnaires, interviews, focus groups, and market surveys, we gathered data from 321 respondents. PCA was performed to analyze threats and plant use using "factoextra" in R software. Origin Pro was used to create a chord diagram, while R software was used to generate a Polar heat map. Additionally, a Venn diagram was created using Bioinformatics software. The study included 321 informants, of whom 75.38% were men and 24.61% were women. In total, 113 plant taxa from 74 genera and 41 botanical families were reported. Polygonaceae and Rosaceae accounted for the majority (17 species each), followed by Lamiaceae (7 species). Leaves were the most used part as food sources (41.04%), followed by fruits (33.33%). Most of the species are consumed as cooked (46.46%) and as raw snacks (37.80%). A total of 47 plant species were collected and cooked as wild vegetables, followed by 40 species used as fruits. This study is the first to describe the market potential and ecological distribution of WFPs in the study area. Cross-comparison showed that utilization of WFPs varies significantly across the region and communities, including their edible parts and mode of consumption. Jaccard index (JI) value ranged from 5.81 to 25. Furthermore, the current study describes 29 WFPs and 10 traditional food dishes that have rarely been documented in Pakistan's ethnobotanical literature. Climate change, invasive species, expansion of agriculture, and plant diseases are some of the most significant threats to WFPs in the study area. The older age group has more knowledge about WFPs compared to the younger generation, who are not interested in learning about the utilization of WFPs. This lack of interest in information about WFPs among the younger generation can be attributed to their limited access to markets and availability of food plants

This study, based on 35 historical written sources and 581 in-depth semi-structured interviews from eight countries in the western borderlands of the former Soviet Union, investigates the medicinal use of fungi by local communities. We compared the taxa and uses obtained from fieldwork and historical sources with works that advocated fungi use within Soviet herbals, representing the centralised medical system. During fieldwork, we identified eight locally used fungi and one lichen. The highest numbers of medicinal uses were documented in Russia, Estonia and Ukraine. Studies published before the Soviet era listed 21 fungal taxa and one lichen species used in the study region. However, only six of these taxa were mentioned as used by people in our field studies (Amanita muscaria, Boletus edulis, Lycoperdon, Morchella, Phallus impudicus and Cetraria islandica). Notably, these same six taxa were consistently endorsed in Soviet herbals. Of the remaining three taxa recorded in the fieldwork, none were mentioned in historical written sources. However, they were promoted either in Soviet herbals (Inonotus obliquus, Kombucha) or later popular publications (Cantharellus cibarius). This highlights the significant influence of written sources on the use of fungi for medicinal purposes within the studied local communities.

Their significance extends beyond mere sustenance, intertwining with cultural traditions and local knowledge systems, underscoring the importance of preserving biodiversity and traditional practices for sustainable livelihoods. Methods The present study, conducted between February 2022 and August 2023 along the Line of Control in India's Kashmir Valley, employed a rigorous data collection encompassing semi-structured interviews, focus group discussions, and specific field observations facilitated through a snowball sampling technique. Results and discussion The comprehensive inventory includes 108 edible plant and fungal species from 48 taxonomic families, with Rosaceae (N = 11) standing out. Young and soft leaves (N = 60) are an important component of various culinary preparations, with vegetables (N = 65) being the main use, followed by fruits (N = 19). This use is seasonal, with collection peaks in March-April and June-August (N = 12). The study also highlights the importance of use value (UV), with Portulaca oleracea standing out as the plant taxon (UV = 0.61), while Asyneuma thomsoni has the lowest use value (UV = 0.15). Many species such as Senecio chrysanthemoides, Asperugo procumbens, Asyneuma thomsoni, and Potentilla nepalensis were classified as new for gastronomic use. Furthermore, the study underlines the great cultural importance of mushrooms such as Morchella esculenta and Geopora arenicola in influencing social hierarchies within the community. However, the transmission of traditional knowledge across generations is declining in the region. At the same time, the conservation of endangered plant species on the IUCN Red List, such as Trillium govanianum, Taxus wallichiana, Saussurea costus, and Podophyllum hexandrum, requires immediate attention. Conclusion Conservation measures should be prioritized, and proactive remedial action is needed. Further research into the nutritional value of these edible species could pave the way for their commercial cultivation, which would mean potential economic growth for local communities, make an important contribution to food security in the area under study, and contribute to scientific progress.

This study aims to develop a conceptual model of plant knowledge circulation, providing insights into the temporal dynamics of LEK in the Polish-Lithuanian-Belarusian border region. It explores the key patterns and driving forces behind changes in the use of wild plants for food. Methods Field research was conducted in 60 rural settlements across Podlasie Voivodeship (Poland), Vilnius Region (Lithuania), and Hrodna Region (Belarus). This included 200 semi-structured interviews and participant observation among two local communities, Lithuanians and Poles. To assess the temporal dynamics of wild food use, we performed a cross-ethnic, cross-border analysis over time, dividing the data into three major temporal dimensions: past, continuous, and recently acquired uses. Results Of the 72 wild plant taxa reported by Poles or Lithuanians in the Polish-Lithuanian-Belarusian borderland, 47 were continuously used for food, 58 were utilised in the past, and 41 were recently acquired. Crosscountry trends were similar, with Poland showing more past uses. Diachronic comparisons between Poles and Lithuanians in each studied country revealed no significant differences. Recently acquired taxa overlapped considerably with those used continuously and in the past. The most diversely utilised taxa showed the greatest overlaps. By observing the movement of specific plant taxa within various time dimensions, we distinguished overlapping flow variations: retention (3 taxa), decay (11), invention (8), stagnation (17), revitalisation (6), re-invention (3), and knowledge in motion (24). Shifts in the use of wild food plants were influenced by changes in environmental conditions, governmental policies, cultural practices, and economic factors. Conclusion The findings of this study have important implications for improving methods of tracking changes in LEK and enhancing our understanding of the relationship between people and nature. Our results underscore the importance of considering knowledge circulation over time in different directions. Recognising the various stages of knowledge circulation might help in pursuing sustainable solutions that balance the needs of human communities with environmental protection.

Our results showed that, with the exception of the Sardinian Culurgiones, all the other pasta ripiena from Italy likely had a single origin in the northern parts of the country. Based on the proposed evolutionary hypothesis, the Italian pasta are divided into two main clades: a ravioli clade mainly characterized by a more or less flat shape, and a tortellini clade mainly characterized by a three-dimensional shape. The implications of these findings are further discussed.
