Are we romanticizing traditional knowledge? A plea for more experimental studies in ethnobiology.

In answer to the debate question "Is ethnobiology romanticizing traditional practices, posing an urgent need for more experimental studies evaluating local knowledge systems?" I suggest to follow-up on field study results adopting an inclusive research agenda, and challenge descriptive data, theories, and hypotheses by means of experiments. Traditional and local knowledge are generally associated with positive societal values by ethnobiologists and, increasingly also by stakeholders. They are seen as a way for improving local livelihoods, biocultural diversity conservation and for promoting sustainable development. Therefore, it is argued that such knowledge needs to be documented, protected, conserved in situ, and investigated by hypothesis testing. Here I argue that a critical mindset is needed when assessing any kind of knowledge, whether it is modern, local, indigenous, or traditional.

Rural reality contradicts the ethnographic literature-a nationwide survey on folk beliefs and people's affection for the stork in Poland.

BACKGROUND: Due to early synanthropization and ecological and behavioural features, the White Stork Ciconia ciconia became the most cherished of European birds. Rooted in human culture, the species has been well studied; nevertheless, knowledge of people's attitudes and stork-related folk beliefs remain descriptive. Here, we attempt to quantify these issues in the world's largest stronghold of the species, Poland, in the 1950s. METHODS: The study is based on recently discovered, original nationwide survey data from the 1958 International White Stork Census. These materials were gathered to assess the population size, but they also included issues belonging to the humanities. We have worked them up in a quantitative manner, which has resulted in an original approach rarely found in ethnological studies. We aim to propose an original typology of stork-related beliefs, their spread and regional diversity in Poland and the relationship with stork abundance. RESULTS: A sample of 2343 questionnaires revealed that affection towards storks was widespread (91.4% positive responses), more so in eastern Poland. The most frequent beliefs relate to respect for the stork (65%) and prophesies (24%), thereafter parental beliefs (7%) and stork biology (3%). Positive attitudes and the dissemination of beliefs increased with stork densities but were unrelated to the respondents' sex. Utilitarian beliefs outweighed those prioritized in ethnographic studies (e.g. the stork's human origins) or popular today (baby-bringing), and expressed the real concerns of country folk. CONCLUSIONS: The discovery of long-lost data bordering on ethnology and nature conservation and their novel work-up highlights a realistic dimension of the human-nature relationship and provides a benchmark for further interdisciplinary research.

Access restrictions to forest resources, rather than COVID-19 bans, drive the selection of firewood species for bonfires during Festas Juninas in northeastern Brazil.

BACKGROUND: The complex interplay of social and environmental factors shapes ecosystems, potentially leading to harmony or conflict, highlighting the importance of understanding these dynamics for coexistence. In developing countries, firewood serves as a primary energy source and plays a role in cultural-religious rituals and festivities. However, the specific patterns of woody species used for the latter remain poorly understood, including the impact of access restrictions to resources and local bans on practices. Therefore, our research focuses on examining how access restrictions to forest resources and bonfire bans due to the coronavirus disease 2019 (COVID-19) impact the cultural-religious tradition of bonfire making during Festas Juninas (June festivities) in northeastern Brazil. METHODS: Ethnobotanical fieldwork was conducted in two rural populations in northeastern Brazil between 2021 and 2022. Data were collected through semi-structured interviews, observations, and the guided tour technique. The cultural-religious tradition of bonfire making (i.e., richness of native and exotic firewood species, firewood volume, and the number of bonfires related to this practice) was compared between populations (i.e., differing in access restrictions) and years (i.e., differing in COVID-19-related bans) using Mann-Whitney U tests. RESULTS: Results revealed significant differences in the richness of native (p value = 0.001) and exotic (p value < 0.001) firewood species for bonfire making due to access restrictions to forest resources. The number of native species used was higher among the population residing in the area with unrestricted access than among those with restricted access, while a greater number of exotic species was used in the population with restricted access. The rest of the variables were not influenced by access restrictions, and no variables were influenced by COVID-19 bans. CONCLUSIONS: Our study demonstrated that access restrictions to forest resources, rather than COVID-19 bans, drive the selection of firewood species for bonfires during Festas Juninas in northeastern Brazil. In addition, as populations remain deeply entrenched in cultural-religious practices amid temporary bans imposed by health crises, there is a pressing need for culturally sensitive environmental policies. Fostering socio-ecological resilience demands a comprehensive approach that encompasses not only environmental factors but also cultural dimensions, which wield a pivotal influence on long-term sustainability.

Wildlife as Food and Medicine in Brazil: A Neglected Zoonotic Risk?

The practice of consuming wild fauna in Brazil is both culturally and socioeconomically questionable. Wild animals and their byproducts are sought for nutritional, medicinal, and/or supernatural reasons, with some taxa (e.g., songbirds) being kept as pets. This practice is concentrated in traditional and rural communities, as well as the rural exodus populations in large urban centers, maintained both by cultural preferences and for their role in food safety in part of the rural exodus community. A total of 564 taxa are known to be sold in wet markets in Brazil, with birds, fish, and mammals being the most commonly listed. There is great zoonotic outbreak potential in this consumption chain given the diversity of species involved (with several listed being known reservoirs of zoonotic pathogens), invasion of wild environments for hunting, unsanitary processing of carcasses, and consumption of most/all biotopes of the animal, as well as the creation of favorable conditions to cross-species pathogen transmission. Given its socioeconomic situation and the global trends in disease emergence, there is a risk of the future emergence of a Public Health Emergency of International Concern in Brazil through wildlife consumption.

Critical areas for sea turtles in Northeast Brazil: a participatory approach for a data-poor context.

Fishing is one of the main threats to sea turtles due to the risk of entanglement in lost nets, vessel collision and mortality due to incidental catches. In Brazil, most of the studies regarding fishing interactions with sea turtles are focused on pelagic longline fisheries in the South and Southeast regions. However, their main reproductive areas in Southwest Atlantic RMU occur in Northeast Brazil, which overlaps small-scale coastal gillnet fisheries. Here, we aimed to use ethnobiology and participatory approaches as simple and cost-effective methods to identify areas for sea turtle conservation where impacts from small-scale fisheries are most likely. Expert captains were trained to recording sea turtle sightings during navigations from the landing port to the fishing grounds, informing their folk nomenclatures. By interpolation of environmental data (chlorophyll and bathymetry) and ecological data, we predicted habitats of 3,459.96 km² for Caretta caretta, Chelonia mydas, and Eretmochelys imbricata and fishing zones of 1,087 km² for management in 20 m and 50 m depths. Our results contributes to ongoing discussions of bycatch mitigation for sea turtle species and identification of habitats. We highlights the importance of considering particularities of overlapped areas in marine spatial planning and co-management arrangements.

Traditional knowledge of animal-derived medicines used by Gelao community in Northern Guizhou, China.

INTRODUCTION: This study aims to document and preserve the traditional medicinal knowledge of the Gelao community in Northern Guizhou, China, providing valuable insights for modern pharmacological research and the development of these traditional remedies. METHODS: Our methodology encompassed a blend of literature review, community interviews, and participatory observation to delve into the traditional knowledge of animal-derived medicines among the Gelao community. We employed quantitative ethnological and ecological assessment techniques to evaluate the significance of these practices. Informed consent was secured before conducting interviews, with a focus on ascertaining the types of medicines familiar to the informants, including their local names, sources, methods of preparation, application techniques, diseases treated, frequency of use, and safety considerations. RESULTS: Our research cataloged 55 varieties of animal-derived medicines utilized by the Gelao people. Out of these, 34 originate from wild animals, mainly encompassing small insects, reptiles, and aquatic species; the remaining 21 are derived from domesticated animals, largely involving their tissues, organs, and various physiological or pathological by-products. These medicines are primarily applied in treating pediatric ailments (13 types), internal disorders (11 types), gynecological issues (3 types), dermatological problems (7 types), ENT conditions (3 types), trauma-related injuries (5 types), joint and bone ailments (5 types), infections (2 types), dental issues (2 types), and urolithiasis (1 type), with three types being used for other miscellaneous conditions. Commonly utilized medicines, such as honey, Blaps beetle, chicken gallstones, and snake-based products, are preferred for their availability, edibility, and safety within the Gelao communities. CONCLUSION: The Gelao community's traditional medicines represent a rich diversity of animal sources, showcasing extensive expertise and knowledge in their processing and clinical applications. This wealth of traditional knowledge offers novel perspectives for the contemporary pharmacological study and development of these remedies. Additionally, our research plays a crucial role in aiding the preservation and continuation of this invaluable cultural heritage.

Food drugs as drivers of therapeutic knowledge and the role of chemosensory qualities.

ETHNOPHARMACOLOGICAL RELEVANCE: Chemosensory qualities of botanical drugs are important cues for anticipating physiologic consequences. Whether a botanical drug is used for both, food and medicine, or only as medicine depends on taste preferences, nutritional content, cultural background, and the individual and overall epidemiological context. MATERIAL AND METHODS: We subjected 540 botanical drugs described in De Materia Medica having at least one oral medical application to a tasting panel. The 540 drugs were grouped into those only used for medicine (388) and those also used for food (152). The associations with chemosensory qualities and therapeutic indications were compared across the two groups. We considered 22 experimentally assessed chemosensory qualities and 39 categories of therapeutic use groups. We wanted to know, 1): which chemosensory qualities increase the probability of an orally applied botanical drug to be also used for food ? 2): which chemosensory qualities augment the probability of an orally applied botanical drug to be only used for medicine? and 3): whether there are differences in therapeutic indications between orally applied botanical drugs also used for food (food drugs) and botanical drugs applied exclusively for medicinal purposes (non-food drugs) and, if yes, how the differences can be explained. RESULTS: Chemosensory qualities augmenting the probability of an orally applied botanical drug to be also used for food were sweet, starchy, salty, burning/hot, fruity, nutty, and cooling. Therapeutics used for diarrhoea, as libido modulators, purgatives, laxatives, for expelling parasites, breast and lactation and increasing diuresis, were preferentially sourced from food drugs while drugs used for liver and jaundice, vaginal discharge and humoral management showed significant negative associations with food dugs in ancient Greek-Roman materia medica. CONCLUSION: Therapeutics used for ailments of body organs involved in the digestion of food and the excretion of waste products showed a tendency to be sourced from food drugs. Arguably, the daily consumption of food offered the possibility for observing post-prandial physiologic and pharmacologic effects which led to a high therapeutic versatility of food drugs and the possibility to understand benefits of taste and flavour qualities. The difference in chemosensory qualities between food drugs and non-food drugs is demarcating the organoleptic requirements of food rather than that of medicine.

Making the most of scarce biological resources in the desert: Loptuq material culture in Eastern Turkestan around 1900.

BACKGROUND: Most fisher-gatherer communities we know of utilized a limited number of natural resources for their livelihood. The Turkic-speaking Loptuq (exonym Loplik, Loplyk) in the Lower Tarim River basin, Taklamakan desert, Eastern Turkestan (Xinjiang), were no exception. Their habitat, the Lop Nor marsh and lake area, was surrounded by desert and very poor in plant species; the Loptuq had to make the most of a handful of available biological resources for housing, furniture, clothing and fabric, fishnets and traps, tools and other equipment. The taxa used by the Loptuq were documented by foreign explorers at the end of the nineteenth and beginning of the twentieth centuries, prior to the forced resettlement of the group in the 1950s and subsequent destruction of their language, lifestyle and culture. METHODS AND SOURCES: Ethnobiology explores the relationship between humans and their environment, including the use of biological resources for different purposes. In several aspects, historical ethnobiology is more challenging; it studies this relationship in the past and therefore cannot verify results with informants. As the present study discusses an extinct culture on the basis of literary and material sources, we apply a method called source pluralism. This approach allows the inclusion and combination of a wide range of data and materials, even scraps of information from various sources, with the aim to understand phenomena which are sparsely mentioned in historical records. Travel reports by Swedish, British, German, American and Russian explorers together with linguistic data provide the most important sources for understanding Loptuq interaction with the environment and its biota. Especially the large number of toponyms and phytonyms recorded by the Swedish explorer Sven Hedin and materials from his expeditions, including voucher specimens kept in Stockholm in the herbarium of the Swedish Natural History Museum, and objects of material culture in the collections of the Ethnographical Museum, are crucial for our analysis about local knowledge among the Loptuq. Illustrations and photographs provide us with additional information. RESULTS: The question of how the Loptuq managed to survive at the fringe of a desert, a marsh and a lake which changed its location, intrigued all foreign visitors to the Lop Nor. The Loptuq's main livelihood was fishing, hunting and gathering, and their material culture provided by plants and other organic materials included their usage, consumption and trade. Only a handful of species formed the basis of the Loptuq material culture, but they had learned to use these specific plants for a variety of purposes. The most important of these were Lop hemp, Poacynum pictum (Schrenk) Baill., the riparian tree Euphrates poplar, Populus euphratica Olivier, and the aquatic common reed, Phragmites australis (Cav.) Trin. ex Steud. Several species of tamarisk were used for fuel and building fences. A few plants were also harvested for making foodstuffs such as snacks and potherbs. In addition, the Loptuq also used fur, bird skins, down, feathers, mammal bones and fish bones for their material needs. The habitat provided cultural ecological services such as motifs for their folklore, linguistic expressions and songs, and the Loptuq engaged in small-scale bartering of plant products and furs with itinerant traders, which ensured them with a supply of metal for making tools. CONCLUSION: This article discusses the now extinct Loptuq material culture as it existed more than a hundred years ago, and how the scarce biological resources of their desert and marsh habitat were utilized. Loptuq adaptation strategies to the environment and local knowledge, transmitted over generations, which contributed to their survival and subsistence, were closely connected with the use of biological resources. For this study, a comprehensive approach has been adopted for the complex relationships between human, biota and landscape. The Loptuq are today largely ignored or deleted from history for political reasons and are seldom, if at all, mentioned in modern sources about the Lop Nor area. Their experience and knowledge, however, could be useful today, in a period of rapid climate change, for others living in or at the fringe of expanding deserts.

The influence of exotic and native plants on illnesses with physical and spiritual causes in the semiarid region of Piauí, Northeast of Brazil.

BACKGROUND: Local medical systems (LMS) include native and exotic plants used for the treatment of diseases of physical and spiritual nature. The incorporation of exotic plants into these systems has been the subject of many studies. In this context, an analysis was conducted on the influence of the origin of plants on diseases of physical and spiritual nature in order to evaluate the therapeutic versatility of native and exotic species in these therapeutic targets, to investigate whether exotic plants mainly fill gaps not met by native plants (diversification hypothesis), and identify which species are prioritized in the redundant targets in these two therapeutic groups in the rural community of Morrinhos, Monsenhor Hipólito, Piauí. METHODS: Data collection took place in 2 stages. First, free lists and semi-structured interviews with local residents (n = 134) were conducted to survey plants used for therapeutic purposes and the associated illnesses. Then, another phase of interviews was carried out to evaluate the prioritization between native and exotic plants in redundant therapeutic targets. To test the diversification hypothesis (DH) in each group of illnesses, data were analyzed using generalized linear models (Poisson and Binomial GLMs); versatility was measured by the number of therapeutic indications and compared between resources using the Mann-Whitney test, and prioritization in each group was verified by comparing the proportions of native and exotic plants with the χ2 test. RESULTS: One hundred and thirty-two species of plants were surveyed, being 71 exotic and 61 native, with indications for physical and spiritual illnesses. The results revealed that the diversification hypothesis did not explain the inclusion of exotic plants in the local medical system to treat physical or spiritual illnesses and that the therapeutic versatility of exotic and native resources in the two groups was also similar (p > 0.05). However, exotic plants were prioritized in illnesses with physical causes and native plants in illnesses with spiritual causes. CONCLUSIONS: The local medical system presents similar and distinct patterns in the therapeutic targets, depending on the perspective evaluated. Therefore, it is necessary to investigate the patterns of use of medicinal plants in different sociocultural contexts in order to broaden the debate about the role of plant origin in the selection of treatments for illnesses with different causes.

Taste shaped the use of botanical drugs.

The perception of taste and flavour (a combination of taste, smell, and chemesthesis), here also referred to as chemosensation, enables animals to find high-value foods and avoid toxins. Humans have learned to use unpalatable and toxic substances as medicines, yet the importance of chemosensation in this process is poorly understood. Here, we generate tasting-panel data for botanical drugs and apply phylogenetic generalised linear mixed models to test whether intensity and complexity of chemosensory qualities as well as particular tastes and flavours can predict ancient Graeco-Roman drug use. We found chemosensation to be strongly predictive of therapeutic use: botanical drugs with high therapeutic versatility have simple yet intense tastes and flavours, and 21 of 22 chemosensory qualities predicted at least one therapeutic use. In addition to the common notion of bitter tasting medicines, we also found starchy, musky, sweet, and soapy drugs associated with versatility. In ancient Greece and Rome, illness was thought to arise from imbalance in bodily fluids or humours, yet our study suggests that uses of drugs were based on observed physiological effects that are often consistent with modern understanding of chemesthesis and taste receptor pharmacology.

In ancient times people used trial and error to identify medicinal plants as being effective. Later, diseases were believed to arise from imbalances in body fluids (or 'humours'), and botanical drugs were thought to restore this balance through the power of their taste. Modern science rejects this theory but does recognise the importance of chemosensation ­ our sensitivity to chemicals through taste and smell. These senses evolved in humans to help us seek out nutrients and avoid toxins and may also have guided the ancient uses of botanical drugs. There are many records of historical medicinal plant use and ailments, which makes it possible to explore possible relationships between therapeutic uses of botanical drugs and their chemosensory qualities. To investigate if therapeutic uses of botanical drugs could indeed be predicted by taste and flavour, Leonti, Baker et al. collected 700 botanical drugs identified in an ancient text, named De Materia Medica, which dates back to the 1^st century CE. The researchers asked volunteer tasters to classify the botanical drugs using 22 taste descriptions, such as bitter, aromatic, burning/hot, and fresh/cooling. The volunteers were also asked to score the strength of these tastes. Leonti, Baker et al. then used statistical modelling to see if the participant's taste descriptions could be used to predict the therapeutic uses of the drugs identified in the ancient text. This revealed that of the 46 therapeutic indications described in the text, 45 showed significant associations with at least one taste quality. Botanical drugs with stronger and simpler tastes tended to be used for a wider range of therapeutic indications. This suggests that chemosensation influenced therapeutic expectations in ancient, prescientific medicine. The study of Leonti, Baker et al. brings ancient medicine to life, offering valuable insights into the chemosensory aspects of medicinal plants and their potential applications in modern medicine. A next step would be to explore whether these insights could have relevance to modern science.

Brazilian Environment and Plants as Seen by Japanese Eyes Two Hundred and Twenty Years Ago.

In 2023, the Japanese migration to Brazil completed 115 years. However, the first time Japanese people arrived in Brazil and left a testimony of their experience was about two centuries ago. Their reports were registered in a historical document, handwritten during the Edo period when Japan was adopting a closed-door policy. The episode of their visit to Brazil is only a small part of the odyssey of these four Japanese sailors who departed from Ishinomiya to Tokyo at the end of the 18th century, but unexpectedly traveled around the globe. After a storm, they were adrift for six months until shipwrecking on the Aleutian Islands; from the Russian Aleutian Islands, they crossed the whole of Russia and boarded, in Saint Petersburg, on the first Russian expedition to circumnavigate the world. Their only stop in South America was at Santa Catarina Island, southern Brazil, and this is the first analysis of this episode from an ethnobiological perspective. Their reports described both the forest environment and the plants they observed and included at least 23 taxa of plants, mostly cultivated. These descriptions of plants and the environment are in contrast with other reports from the same period and to the current environment found in Santa Catarina Island, inspiring reflections on the construction of Brazil's image in Japan before the 20th century.

Integrating depth and rigor in ethnobiological and ethnomedical research.

Ethnobiology and ethnomedicine, traditionally descriptive disciplines chronicling Indigenous People and Local Community (IPLC) practices, face the challenge of incorporating hypothesis-driven research to address contemporary issues. This paper argues for a synergistic approach where both approaches are valued for their unique contributions to understanding human-nature interactions and informing policy.

Interactions between local medical systems and the biomedical system: a conceptual and methodological review in light of hybridization subprocesses.

Local medical systems (LMSs) are complex and dynamic, encompassing local perceptions of diseases, prevention and treatment strategies, and evaluations of therapeutic responses. These systems are not isolated and interact with other medical systems, such as the biomedical system. The interaction between these systems creates a "contact zone", which some authors refer to as intermedicality, involving both competitive and complementary interactions. However, there is limited discussion in the literature regarding the complexity of these interactions. Some studies seek to understand this interaction through the lens of hybridization, a concept introduced to ethnobiology by Ana Ladio and Ulysses Albuquerque. The authors conceptualize hybridization as "discrete structures and practices coming together to form a new practice not necessarily implying homogenization." They discuss hybridization in the context of medicinal plants used in urban settings and propose seven hybridization subprocesses to gain a deeper understanding of this phenomenon. In this study, we update these hybridization subprocesses, expanding the concepts to comprehend the specific interaction of resources from LMS and biomedical systems known and used by different human groups. In this context, we propose a new subprocess and have made adjustments to the existing subprocesses to encompass the diversity of possible interactions between medicinal plants and pharmaceuticals, providing evidence from the literature demonstrating interactions that can be classified within the proposed subprocesses. Furthermore, we discuss, from a theoretical standpoint, how these subprocesses may have implications for the resilience of medical systems. Moreover, we propose a flowchart that can be utilized to identify these hybridization subprocesses in intermedicality contexts in future studies. These classifications are crucial because they enable us to comprehend the complexity of interactions between medicinal plants and pharmaceuticals, as well as the impacts that these different interactions can have on the resilience of LMSs.

Ethnobotanical contributions to global fishing communities: a review.

BACKGROUND: Ethnobotanical knowledge about the role of plants in fisheries provides valuable ecological information vital for sustainable management of local resources; however, it is diluted and understudied globally. This literature review aims to map the knowledge of plant use within traditional fishing communities. METHODS: Through the PRISMA method, we identified and selected 34 articles reporting the use of plants in fisheries, and including 344 taxa of plants and algae. Uses of plants and algae were grouped into different categories. RESULTS: In the novel categorization of fishery-related uses we proposed, the most mentioned were for fishing and building/repair of fishing artifacts and habitat-related uses, while the records of plants related to fiber uses, providing aid in fishing management and species causing problems, were among the least mentioned. Semi-structured interview is most commonly used with local resource users, especially fishery experts, in exploring perceptions on plant use within traditional fishing communities. Diversity was high in all the recorded families, but most were reported locally. CONCLUSION: Ethnobotanical studies with fishers are not common in the documented literature but they provide a large number of use reports. On the basis this review, in most of the world, the information is of a casual and sporadic nature. Fishers can provide information on aquatic plants and algae that create problems and aid in fishing management, which are crucial in understanding the ecosystem of a region experiencing environmental challenges. This knowledge is greatly understudied globally and undergoing a rapid decline, as highlighted in several of the reviewed articles. Thus, further systematic research on fishery-related uses of plants by fisherfolk is needed considering its potential contribution to the sustainable management of fishery resources.

The 'biocultural approach' in Latin American ethnobiology.

Contemporary ethnobiologists employ the biocultural approach to different contexts and countries, and they seek to describe the relationship between biological and cultural diversity. For Latin American researchers, this approach is particularly interesting from a critical standpoint. We offer a review of the concept of "biocultural", departing from Mexican ethnobiologist contributions. Later, we analyze different uses of this concept in several regional meetings, including the SOLAE Congress of 2015 in Colombia, the SOLAE Congress of 2017 in Ecuador, and the SOLAE Congress of 2019 in Bolivia. Likewise, we reflect on the 2018 congress at Belém do Pará, Brazil, which commemorated the creation of the ISE there thirty years earlier. We argue that the importance of the biocultural approach becomes influential insofar as non-academic and academic people meet and promote Latin American discussion in terms of local realities.

Bitter Is Better: Wild Greens Used in the Blue Zone of Ikaria, Greece.

The current study reports an ethnobotanical field investigation of traditionally gathered and consumed wild greens (Chorta) in one of the five so-called Blue Zones in the world: Ikaria Isle, Greece. Through 31 semi-structured interviews, a total of 56 wild green plants were documented along with their culinary uses, linguistic labels, and locally perceived tastes. Most of the gathered greens were described as bitter and associated with members of Asteraceae and Brassicaceae botanical families (31%), while among the top-quoted wild greens, species belonging to these two plant families accounted for 50% of the wild vegetables, which were consumed mostly cooked. Cross-cultural comparison with foraging in other areas of the central-eastern Mediterranean and the Near East demonstrated a remarkable overlapping of Ikarian greens with Cretan and Sicilian, as well as in the prevalence of bitter-tasting botanical genera. Important differences with other wild greens-related food heritage were found, most notably with the Armenian and Kurdish ones, which do not commonly feature many bitter greens. The proven role of extra-oral bitter taste receptors in the modulation of gastric emptying, glucose absorption and crosstalk with microbiota opens new ways of looking at these differences, in particular with regard to possible health implications. The present study is also an important attempt to preserve and document the bio-cultural gastronomic heritage of Chorta as a quintessential part of the Mediterranean diet. The study recommends that nutritionists, food scientists, and historians, as well as policymakers and practitioners, pay the required attention to traditional rural dietary systems as models of sustainable health.

Stingless bees: uses and management by meliponiculturist women in the Chaco region of Bolivia.

BACKGROUND: Stingless bees have a great value as main pollinators of wild flowering and cultivated plants, thus playing a fundamental role in the maintenance of biodiversity and food security in Latin America. Despite their importance, stingless bees face numerous threats causing alarming population declines. Moreover, stingless bees have a great cultural and traditional value, since most products from the hive are used for a wide variety of purposes. A growing number of initiatives are encouraging the breeding of these bees, through training courses and modern management techniques. This study documents the knowledge on stingless bees and their products that meliponiculturists from the Chaco region of Bolivia have, as well as the influence that meliponiculture initiatives have on the management and general knowledge of the bees. METHODS: Local richness and diversity of stingless bees was calculated using Hill numbers. Structured interviews were conducted with 59 meliponiculturists in order to characterize traditional and formal knowledge on stingless bees and meliponiculture. Generalized linear models were applied to assess the influence of training courses on the management of the bees. Also, a relative cultural importance index was calculated for each species. RESULTS: Twelve Meliponini species were identified, and 15 local names were reported with morphological, defensiveness behavior, and nest description. There was no significant difference in the knowledge between different ethnical backgrounds or ages. A significant difference was observed in the use of supplementary feeding and assisted division, but none in the success in racking hives or in pest management, regarding the number or courses taken. The relative cultural importance index recorded 30 specific uses for bee products grouped in four categories, from which 29 were attributed (but not exclusively) to Tetragonisca angustula, making it the most versatile species. CONCLUSIONS: The products of the hive, especially honey, are used for a wide variety of purposes, mostly in medicine. These uses are mostly attributed to just one species, T. angustula, in coincidence with what was taught in meliponiculture training courses by NGOs. The influence of formal knowledge is mostly positive, but it is recommended that other meliponini species are taken into account as well.

Fishers' multidimensional knowledge advances fisheries and aquatic science.

Fishers' Indigenous and local knowledge (ILK) has multidimensional contributions to improve fisheries and aquatic ecosystems science, ranging from algae to whales and including management, conservation, ecology, and impact assessment. The challenges are to sustain this knowledge, recognize its value, and to include ILK holders in resource management and decision-making.

Medicinal plants used by shepherds in Trans-Himalayan Rakchham-Chitkul Wildlife Sanctuary in Baspa Valley of Kinnaur district, Himachal Pradesh, India / Plantas medicinales utilizadas por los pastores en el Santuario de Vida Silvestre Rakchham-Chitkul Trans-Himalayan en el distrito de Baspa Valley of Kinnaur, Himachal Pradesh, India

Traditional Uses of Animals in the Himalayan Region of Azad Jammu and Kashmir.

Background: The use of animals and animal-derived products in ethnopharmacological applications is an ancient human practice that continues in many regions today. The local people of the Himalayan region harbor rich traditional knowledge used to treat a variety of human ailments. The present study was intended with the aim of examining animal-based traditional medicine utilized by the population of the Himalayan region of Azad Jammu and Kashmir. Methods: Data were collected from 2017 to 2019 through individual and group interviews. Data on traditional uses of animal products were analyzed, utilizing following indices such as the frequency of citation, use value, relative importance, similarity index, principal component analysis, and cluster analysis to find the highly preferred species in the area. Results: Ethnomedicinal uses of 62 species of vertebrates and invertebrates were documented. Flesh, fat, bone, whole body, milk, skin, egg, head, feathers, bile, blood, and honey were all used in these applications. The uses of 25 animals are reported here for the first time from the study area (mainly insects and birds, including iconic species like the kalij pheasant, Lophura leucomelanos; Himalayan monal, L. impejanus; and western tragopon, Tragopan melanocephalus). The diversity and range of animal-based medicines utilized in these communities are indications of their strong connections with local ecosystems. Conclusion: Our results provide baseline data valuable for the conservation of vertebrate and invertebrate diversity in the region of Himalayan of Azad Jammu and Kashmir. It is possible that screening this fauna for medicinally active chemicals could contribute to the development of new animal-based drugs.
