Passive acoustic monitoring has become a widely used method to study cetaceans, especially for populations facing escalating threats from noisy human activities, including shipping traffic, fishing industry and marine constructions. Here, we conducted a study using an autonomous surface vehicle to explore the distribution and acoustic behavior of cetaceans and to characterize anthropogenic sound sources in the central Mediterranean Sea. A wave glider equipped with a single-towed acoustic recorder was deployed from 13th September 2022 to 3rd March 2023. The recording yielded 19,115 files of 460s each (approximately 2 TB), a third of which was kept for a preliminary analysis based on spectrogram visualization and audio listening. The results showed that nearly half of the dataset contained delphinid signals (Delphinidae), followed by sperm whales (Physeter macrocephalus) and fin whales (Balaenoptera physalus), with notable hotspots in the southern Tyrrhenian and the Ionian Sea. Moreover, the almost continuous detection of anthropogenic sources highlighted the widespread acoustic impact of human activities in the area. These findings demonstrate the value of passive acoustics in the use of autonomous vehicles as a versatile tool for large-scale and long-term monitoring, offering a promising approach to support conservation efforts for vulnerable species while advancing strategies to mitigate human impacts on marine ecosystems.

BackgroundThis study explores the continuity and transformation of wild plant foraging practices in Biella, Piedmont (northwestern Italy), over the past 55 years. The aim was to assess how cultural, economic, and environmental shifts have shaped local ethnobotanical knowledge and practices, using a 1970 survey as a baseline for comparison. Ethnobotanical fieldwork was conducted with 15 local informants to document current wild plant uses for food and herbal teas.ResultsThe resulting dataset of 82 species was compared with a historical record of 93 species to identify patterns of continuity, loss, and innovation. Three main patterns emerged: (1) the disappearance of certain traditionally foraged plants, not due to ecological absence but largely because of socio-economic changes like the decline of pastoralism and the loss of daily interaction with mountain environments (2) the emergence of new foraging practices involving species that grow near settlements, linked to evolving lifestyles and land use; and (3) a relatively robust preservation of traditional ecological knowledge when compared to other Alpine areas. This resilience is attributed to the area’s geographic marginality, the socio-economic aftermath of the textile industry’s collapse, and the strength of local traditions such as home gardening and communal land use.ConclusionWild plant foraging remains a living tradition in Biella, marked by both persistence and adaptation. The findings underscore the dynamic nature of ethnobotanical knowledge and its potential role in sustainability, food security, and cultural heritage preservation amid rural and peri-urban change.

The transformation of Local Ecological Knowledge (LEK) among minority populations undergoing cultural and linguistic assimilation over time is poorly understood. Arbëreshë communities in Greece, who have preserved Albanian-derived traditions for centuries, offer a unique opportunity to examine how folk plant knowledge adapts over time. This study examines the linguistic labels and culinary uses of wild greens among Arbëreshë (or Arvanites), an ethno-linguistic minority traditionally speaking Arbërisht or Arvanitika, the Tosk dialect of Albanian, who have resided in the Argolis and Corinthia regions of the Peloponnese for several centuries. In 2025, fieldwork was conducted in four rural Arbëreshë villages in the Argolis and Corinthia regions of Greece, combining semi-structured interviews with 24 elderly participants, participant observation, and the collection and identification of botanical specimens. The contemporary dataset was compared with historical ethnobotanical records from the 1970s to assess temporal changes in the use of wild vegetables and folk plant nomenclature. Our results reveal that current Arbëreshë ethnobotanical heritage has undergone profound Hellenisation, with 62% of folk plant names of Greek origin, 14% Albanian, and 24% hybrid, reflecting strong linguistic and cultural assimilation over the past half-century. The traditional boiled green mix (lakra in Arbëreshë, chorta in Greek) remains central to the local cuisine, which is rooted in foraged plants, although its culinary applications have diversified. In total, 37 taxa of wild vegetables across 37 genera and 14 families were documented in 2025, compared with 21 taxa across 21 genera in the filtered 1970 dataset. Core families, such as Asteraceae and Brassicaceae, remained dominant, while new families, like Malvaceae and Portulacaceae, appeared, possibly indicating both ecological and culinary changes. These findings raise questions about whether the Arbëreshë wild vegetable heritage was strongly influenced by the surrounding Greek majority or primarily acquired after migration, potentially facilitated by intermarriages and shared Orthodox Christian affiliation. Overall, our study highlights a largely Hellenised Arbëreshë biocultural heritage and underscores the urgent need for national and regional stakeholders to recognise and celebrate the remaining minority’s linguistic and ethnobotanical diversity. The transformation of local ethnobotanical knowledge over the past fifty years appears influenced by ecological availability, socio-cultural dynamics, and changing taste preferences.

Abstract Bioplastic and polylactic acid production is expected to increase in the future to replace single-use traditional plastics. Here we investigated the effects of polylactic acid contamination in marine ecosystems by assessing its degradation over time in an experimental mesocosm, along with its impact on microbial abundance, microbiome diversity, viral infections, and rates of organic matter cycling. We report here that, as polylactic acid gradually lost its integrity, a microbial biofilm rich in Marinobacter sp. developed on the biopolymer, reshaping the marine microbiome, promoting polylactic acid-associated bacteria such as the Saccharospirillaceae, and in turn increasing viral activity and accelerating the degradation of organic matter. These effects, which were further amplified at the temperatures experienced during heatwaves, suggest that high levels of polylactic acid contamination might influence the functioning of coastal marine ecosystems, particularly during extreme temperature episodes.

This study investigates climate change perceptions of inhabitants of four distinct physiographic regions of Southern Europe, including Alpine cattle pastoralists of Carinthia (Western Austria), Venice Lagoon farmers, Southern Sicilian Coast fisherfolk, and Langhe winemakers in Italy. Through semi-structured interviews with 92 households conducted between autumn 2022 and autumn 2023, distributed across the four case studies, nuanced variations in perceptions of climate change impacts and responses were analysed. The results illustrate significant associations between climate change perception and various factors including adaptation strategies, precipitation change, and social network influence. Notably, the perceived impacts relate to a decrease in precipitation which affects agricultural production, vegetation shift, and adaptation strategies. Analyses conducted using mixed-effect logistic regression models uncovered varied regional contexts that influence both climate change awareness and adaptive actions. Additionally, Principal Component Analysis (PCA) was employed to explore underlying structures and identify key variables contributing to regional variations in climate perception. This r analysis offered insights into the factors that shape perceptions and strategies in each region and underscored the importance of context-specific approaches to climate resilience and adaptation planning, considering the socio-economic, environmental, and cultural factors. Tailored adaptation strategies, informed by robust data and stakeholder engagement, are essential for building resilience and sustainability in local communities facing ongoing environmental challenges.Supplementary InformationThe online version contains supplementary material available at 10.1038/s41598-025-10611-z.

In the mountainous region of Kashmir, wild food plants (WFPs) are vital to traditional food systems and security. Ethnic communities possess rich foraging practices; however, current sociocultural and environmental impacts may affect the transmission of local plant knowledge among younger generations. This study explores traditional foraging practices and provides a cross-cultural analysis of five groups: Gujjar, Bakarwal, Lone, Syed, and Mughal. It investigates gender-based knowledge, intergenerational dynamics of local plant knowledge, and WFP knowledge among various age groups. Data were collected from 191 informants through semi-structured interviews and focus group discussions from March to September 2024. Factor analysis was conducted to analyse perceived threats to WFPs, and a Venn diagram illustrating WFP consumption patterns across groups was created using OriginPro and R software. A total of 63 species were recorded, including 11 fungal species and 52 WFPs. The analysis revealed diverse consumption patterns, with the Gujjar group consuming the most at 59 species, while the Bakarwal group used only 20. Three distinct wild food plant-based ingredients not previously mentioned in the literature were identified: Lagotis cashmeriana (Bakarwal), Fagopyrum cymosum, and Armillaria mellea (Gujjar). The gender-based knowledge analysis shows that women possess more extensive knowledge about WFPs than men, as they frequently engage in harvesting, consuming, and preparing these plants. Participants aged 18-35 accounted for 21.99% of the knowledge and reported on 19 WFPs, primarily from the Gujjar and Bakarwal groups. Cultural transformation among communities has impacted the core body of knowledge, historically transmitted through storytelling during gatherings and events. However, sociocultural changes have affected social structures, impacting the sharing of traditional plant knowledge. The commodification and mobility of food ingredients have altered local practices, particularly in preparing Dryopteris, Diplazium, Pteridium, and Morchella. Preserving biocultural heritage and promoting sustainable foraging practices can enhance economic growth, food security, and rural development by safeguarding plant knowledge and encouraging commercial cultivation.

There is a confirmed and ongoing need to encourage adherence to healthy dietary patterns in the general population in western societies, given their recognized positive impact in preventing non-communicable diseases (NCDs). A potentially very effective solution is the use of digital tools such as apps and web apps, which can reach a large number of people quickly. Still, to be effective, it is necessary to better understand how participant engagement in these interventions works, to identify the motivations that may lead them to drop out, and to evaluate the effectiveness of these interventions. In our study, an innovative web app designed to encourage adherence to the Mediterranean diet (EATMED) was tested in an intervention study, evaluating adherence to the Mediterranean diet before and after the use of the web app in a cohort of people, compared to a control group, using the MEDI-lite questionnaire. The Health and Taste Attitude Scale questionnaire was also administered to all participants to assess interest in healthy foods and diets, as well as attitudes toward food. The study showed that the score of the Food as Reward subscale of the HTAS had a significant effect on dropout from the intervention study, and that the use of the app among participants who remained resulted in a two-point increase in adherence to the Mediterranean diet, according to the MEDI-lite questionnaire. These results indicate the effectiveness of the EATMED tool and provide useful insights into how to understand and mitigate dropout in digital nutrition interventions.

European agriculture faces major challenges in adapting and transforming current farming and food systems to become more sustainable. Agroecology is one transition pathway. However, what is lacking is assessing this transition with adequate tools and methodology. Here, we present the Original Agroecological Survey and Indicator System (OASIS) tool and apply it to farms in Belgium, France, and Italy as an illustration of its functionalities. In total, 53 conventional and organic farmers of three farming systems [crop production (CP); livestock production (LP), and mixed crop–livestock production (CLP)] were interviewed and data were collected for a large range of indicators (scoring from 1 to 5) across five dimensions: agroecological farming practices, economic viability, socio-political aspects, environment and biodiversity, and resilience. Overall, organic farms had slightly higher scores compared to conventional farms for the five dimensions. However, for the adoption of different agroecological practices, a clear difference was found, often with clearly higher scores for organic farms. There were also similar differences regarding most biodiversity and environment indicators and indicators for revenue and income sources. Farms that had higher overall farm scores also obtained a generally significantly higher mark for economic viability. Farmers described many parameters among the socio-political aspects dimension criteria, including several constraints that resulted in lower scores. Contrasting results for different criteria were found for the dimension of resilience, with some farms scoring higher for autonomy and independence from inputs and market, while others scored lower. As an operational result, overall, the OASIS tool proved applicable and useful in assessing agroecology at the farm level and some links beyond. However, further development could improve the tool.
