Traditional ecological knowledge for monitoring Anaphalis javanica (DC.) Sch.Bip. (Asteraceae) in Bromo Tengger Semeru National Park, Indonesia.

Traditional ecological knowledge (TEK) possessed by indigenous communities offers a vital source of information regarding the status and threats faced by species. Anaphalis javanica (DC.) Sch.Bip. commonly known as Javanese edelweiss is a culturally significant species in Indonesia's mountainous regions, yet conservation efforts for it remain limited. We utilized TEK to assess the status and threats to the Javanese edelweiss in Bromo Tengger Semeru National Park, Indonesia. The research aims to assess the distribution, abundance, population trends, and threats faced by Javanese edelweiss using TEK. We interviewed 641 individuals from seven Tengger villages near the park to gather data on the distribution, status, and threats facing the Javanese edelweiss, contributing to conservation efforts. Data were analyzed using generalized linear mixed models and ordinal logistic regression. TEK regarding the Javanese edelweiss was extensive, as 96.3% of respondents recognized the plant. A majority (73.2%) had observed Javanese edelweiss in the wild, yet a significant portion (85%) perceived it as "very rare" or "rare." Furthermore, 50% of respondents reported a decline in its population. Variations in sighting frequency, perceived abundance, and population trends across different locations provide crucial insights for identifying priority areas and shaping community-based conservation strategies for Javanese edelweiss. This research underscores the importance of integrating TEK into conservation planning, emphasizing community involvement for effective and sustainable biodiversity conservation.

Dark local knowledge: the yet-to-be scientifically discovered and locally acknowledged aspects of local knowledge systems.

This essay brings forward the idea that there is more than meets the eye in local knowledge systems than what science can show us now. To comprehend this, we need to make a conceptual jump and look for the "dark matter" (the notion borrowed from astronomy that refers to a hypothetical form of matter that does not interact with light or electromagnetic fields) that can potentially sustain local knowledge. Considering that it is a complex of knowledge, practices, and beliefs contained in TEK, knowledge in LEK does not correspond to the notion of knowledge in science. Therefore, in order to map LEK-science interactions, we will refer to the concept of peoples' knowledge of LEK as acknowledgement and the scientific recognition and awareness of information, facts, and principles as knowledge. Applying this to a Johari Window, we can observe four categories of LEK in a known-unknown/acknowledged-unacknowledged matrix. We can refer to unknown and unacknowledged as dark local knowledge. Indeed, local knowledge systems contain many aspects that modern science cannot yet explain, as a major part of its components are not even considered in scholarly research. Dark local knowledge can potentially provide us with the invaluable touch of experience of countless generations, opening different ways of seeing reality.

Integration of Indigenous Research Methodologies, Traditional Ecological Knowledge and molecular scatology in an assessment of mesocarnivore presence, diet and habitat use on Yurok Ancestral Lands.

Partnerships between Tribes and researchers in wildlife monitoring and application of Traditional Ecological Knowledge (TEK) have taken a variety of forms, and some scholars have noted a need for culturally sensitive approaches. Guided by Indigenous Research Methodologies, this research is coupled with Yurok TEK, or hlkelonah 'ue-megetohl ('to take care of the earth'), enabling an applied, culturally sensitive approach in partnership with the Yurok Tribe. We present results from a molecular scatology study of wildlife within the ancestral territory of the Yurok Tribe. Scats were collected opportunistically on road transects. All samples (N = 132) were analysed via DNA barcoding and results matched to documented 'Oohl 'we-toh (Yurok language) names to determine the depositor species (N = 8). Though there were four focal mesocarnivore species in our study, only bobcat (Chmuuek; Lynx rufus) and gray fox (Wergers; Urocyon cinereoargenteus) were detected as depositor species. Post hoc analyses were conducted to explore distribution, habitat use and selection in a use-availability context, and food habits of these two species. We found almost complete separation of bobcat and gray fox use of transects, as well as indication of partitioning of vegetation cover types and food. We demonstrate an integrated framework of Western and Indigenous sciences that allows the Indigenous researcher to transcend structured academic disciplinary boundaries. Our approach can be modified for partnerships between Tribes, agencies, academics and students for wildlife monitoring in broader geographic regions in various research applications.

Nose of dog, eye of elk, and wolf's liver: exploring the interconnectedness of Indigenous health and foraging among the Dukha reindeer herders of Mongolia.

Recent studies show that Traditional Ecological Knowledge (TEK) of Indigenous Peoples' food systems and the transfer of that knowledge to their children are critical to physical and mental health, promote the transfer of language and culture, and further resilience. The aim of this exploratory, medical ecological study was to document TEK about foraging and plant use among the Dukha, a small, semi-nomadic reindeer herding community in Northern Mongolia. Field research was conducted at multiple remote camps in 2019 and 2023. Methods included semi-structured, open-ended interviews (N = 16), photo identification, and participant observation (N = 34 families). Study Informants identified 27 foraged plants. Results placed Dukha foraging practices within a framework illustrating the interconnectedness of their worldview and cultural norms, including the physical and spiritual aspects of the landscape, with health, illness, and curing. Dukha curative knowledge of the flora aligns with both Traditional Mongolian Medicine (TMM) and scientific studies on healing and preventative care. Through foraging and plant use, the Dukha balance relationships with the land and spirits, benefit from better nutrition and physical activity, utilise healing qualities of indigenous flora, and foster the intergenerational transfer of language and traditional knowledge.

Wildfires as legacies of agropastoral abandonment: Gendered litter raking and managed burning as historic fire prevention practices in the Monte Pisano of Italy.

Agropastoral practices that historically reduced the flammability of Mediterranean landscapes are poorly understood due to state prohibitions and lack of scientific interest. Oral histories, analysis of agronomical writings, transect walks, and ethnographic study of fire managers and community members in the Monte Pisano of Italy, find legacies of traditional agropastoral practices in present-day landscapes. Forest leaf litter raking, largely carried out by women, combined with fire wood cutting and burning to greatly reduce fire risk. Historic stigmatization of traditional burning and ignoring gendered peasant labor have reduced contemporary scientists' and fire managers' understandings of ecological processes and of options for reducing fire risk. Fire managers in the Mediterranean, and in areas around the world affected by rural depopulation, would benefit from a better understanding of traditional agropastoral and fire management practices. Litter raking has been understudied outside Central Europe, is often gendered, and may have important ecological consequences around the world.

Towards richer knowledge partnerships between ecology and ethnoecology.

Indigenous and traditional practices based on ethnoecological knowledge are fundamental to biodiversity stewardship and sustainable use. Knowledge partnerships between Indigenous Peoples, traditional local communities, and ecologists can produce richer and fairer understandings of nature. We identify key topical areas where such collaborations can positively transform science, policy, and practice.

Three major steps toward the conservation of freshwater and riparian biodiversity.

Freshwater ecosystems and their bordering wetlands and riparian zones are vital for human society and biological diversity. Yet, they are among the most degraded ecosystems, where sharp declines in biodiversity are driven by human activities, such as hydropower development, agriculture, forestry, and fisheries. Because freshwater ecosystems are characterized by strongly reciprocal linkages with surrounding landscapes, human activities that encroach on or degrade riparian zones ultimately lead to declines in freshwater-riparian ecosystem functioning. We synthesized results of a symposium on freshwater, riparian, and wetland processes and interactions and analyzed some of the major problems associated with improving freshwater and riparian research and management. Three distinct barriers are the lack of involvement of local people in conservation research and management, absence of adequate measurement of biodiversity in freshwater and riparian ecosystems, and separate legislation and policy on riparian and freshwater management. Based on our findings, we argue that freshwater and riparian research and conservation efforts should be integrated more explicitly. Best practices for overcoming the 3 major barriers to improved conservation include more and sustainable use of traditional and other forms of local ecological knowledge, choosing appropriate metrics for ecological research and monitoring of restoration efforts, and mirroring the close links between riparian and freshwater ecosystems in legislation and policy. Integrating these 3 angles in conservation science and practice will provide substantial benefits in addressing the freshwater biodiversity crisis.

Tres grandes pasos hacia la conservación de la biodiversidad ribereña y de agua dulce Resumen Los ecosistemas de agua dulce y los humedales y zonas ribereñas que los bordean son vitales para la sociedad y la biodiversidad. Sin embargo, se encuentran entre los ecosistemas más degradados en donde las declinaciones graves de la biodiversidad son causadas por actividades humanas como el desarrollo hidroeléctrico, la agricultura, la silvicultura y las pesquerías. Puesto que los ecosistemas de agua dulce se caracterizan por tener un vínculo recíproco con los paisajes que los rodean, las actividades humanas que invaden o degradan las zonas ribereñas terminan en la declinación del funcionamiento del ecosistema ribereño de agua dulce. Sintetizamos los resultados de un simposio sobre los procesos e interacciones de agua dulce, ribereños y de humedales y analizamos algunos de los principales problemas asociados con la mejora de la investigación y gestión de agua dulce y ríos. Tres barreras claras son la falta de participación de la población local en la investigación y gestión de la conservación, la ausencia de una medición adecuada de la biodiversidad en los ecosistemas de agua dulce y ribereños, y una legislación y política separadas sobre la gestión ribereña y de agua dulce. Con base en nuestros hallazgos, argumentamos que la investigación y los esfuerzos de conservación de agua dulce y ríos deberían integrarse de manera más explícita. Las mejores prácticas para sobreponerse a las tres grandes barreras incluyen un mayor uso sustentable de los conocimientos tradicionales y otras formas de conocimiento, la selección de medidas apropiadas para la investigación ecológica y el monitoreo de los esfuerzos de restauración y la replicación de los vínculos cercanos entre los ecosistemas ribereños y de agua dulce en la legislación y en las políticas. La integración de estos tres ángulos dentro de las ciencias y prácticas de conservación proporcionará beneficios importantes en la manera de abordar la crisis de la biodiversidad de agua dulce.

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.

Traditional ecological knowledge sustains due to poverty and lack of choices rather than thinking about the environment.

In this debate article, we have tried to discuss Traditional Ecological Knowledge (TEK) and its close link to the available resources and lack of options in the indigenous communities. We came across the article of Hartel et al. where they initiated a discussion on this important but debatable topic of TEK and its merits and demirits for the environment. We believe that this discourse could continue to clarify both sides of the picture. Our research group is working on species facing extinction threats due to extensive utilization, leading to overexploitation of the taxa, which the TEK seldom cares for. We are of the opinion that the marginalized tribal communities living around the globe extensively use some of the species and natural resources for their food, fodder, fiber, shelter, energy, health and other benefits, irrespective of their conservation needs, and many other ecosystem services. They have to sustain their basic live's needs from the resources available for their livelihood. They collect economically important medicinal and other species in large quantities to gain higher earnings, rather than thinking of the issues faced by them. Hence, we believe that the continuity and utilization of TEK are driven by poverty and lack of choices rather than positive environmental values, historically. Nevertheless, those communities sometimes have their local system of protection which sometimes works very well or otherwise with the passage of time and the formation of government-driven regulations in the recent past, TEK itself has lost its real sense especially, related to conservation and management. Therefore, TEK could be linked with existing research-based policies and regulations for long-lasting benefits to the environment and its sustainable future. Such bridging can benifit all the stake hoders-the TEK holders, regulatory bodies, government agencies and many more. This debate can lead to a positive and critical discourse towards the clarification of the conundrum under consideration as well as creation of more questions hyptheses related to TEK.

Foraging Wild Edibles: Dietary Diversity in Expanded Food Systems.

Human food foraging in community forests offers extensive and expandable sources of food and high-quality nutrition that support chronic disease prevention and management and are underrepresented in US diets. Despite severe gaps in non-commercial "wild food" data, research in Syracuse, NY, identified substantial amounts of five key antioxidant phytochemicals in locally available, forageable foods with the potential to augment local dietary diversity and quality. Findings endorse the need for micro- and macro-nutrient research on an expanded range of forageable foods, community nutrition education on those foods, an expanded study on antioxidant phytochemical function, and the inclusion of forageables in the food system definition.

Genetic analysis of two species of Mnomen in the Kalamazoo Watershed reveal panmixia in Z. Aquatica, structure among Z. Palustris, and hybridization in areas of sympatry.

Mnomen or wild rice of the genus Zizania is an important part of Native American culture, especially in Michigan for the Ojibwe nation. An oil spill in 2010 along the Kalamazoo River and the subsequent clean-up lead to renewed interest in management of Mnomen within the Kalamazoo watershed. The affected water bodies were surveyed for Zizania species to map existing populations, determine the existing genetic diversity and species present, and to identify potential hybridization. Using Traditional Ecological Knowledge of rice beds and opportunistic sampling of encountered plants, 28 rice beds were sampled. Two species of Zizania were identified Z. palustris and Z. aquatica. Genetic diversity was measured using 11 microsatellite loci and was moderately high for both species (Z. aquatica HE = 0.669, H0 = 0.672, n = 26 and Z. palustris HE = 0.697, H0 = 0.636, n = 57). No evidence of population bottle-necking was found. Z. palustris was found to have k = 3 populations on the landscape, while Z. aquatica was found to be a single panmictic population. Several individual hybrids were confirmed using genotyping and they were all found in areas where the two species co-occurred. Additionally, Z. aquatica was found to have expanded into areas historically with only Z. palustris downstream of the oil spill, potentially due to dredging and sediment relocation as part of the clean-up effort.

Recognising Indigenous plant-use histories for inclusive biocultural restoration.

Indigenous Peoples have manipulated environments and species for millennia. However, restoration science often overlooks ancient human plant dispersal, niche construction, and selection pressures that may have resulted in plant 'cultural traits'. Concerted efforts to acknowledge Indigenous plant-use histories in restoration could help to abate the coextinction of species and cultures.

Monitoring Genetic Erosion of Aromatic and Medicinal Plant Species in Alentejo (South Portugal).

The main goal of this work was to study the genetic erosion risk of plants with aromatic, medicinal and gastronomic applications in Portugal, particularly in the Alentejo region. The target species were coriander (Coriandrum sativum L.), hart's pennyroyal (Mentha cervina L.) and pennyroyal (Mentha pulegium L.). The methodology involved direct observations and surveys (2002/2003 and 2011). The GE formula applied in Hammer's studies was used to estimate genetic erosion. The main factors causing genetic erosion were the primary drivers of biodiversity loss: habitat loss, invasive species, and overexploitation influenced by human intervention such as the clearing of watercourses, vegetation control, grazing and desertification. The results indicate a reduction in individuals per species in Alentejo, with a net erosion loss of 11% for M. pulegium, 32% for M. cervina and 33% for C. sativum. The overall loss of accessions (genetic erosion risk) was higher in cultivated accessions (33%) than in wild accessions (11%), with an annual genetic erosion rate of 3.7% and 1.2%, respectively. The annual risk of genetic erosion for M. pulegium accessions collected in a natural habitat was 0.6%, which is much lower than the 3.7% for M. cervina. These results consolidate the importance of collecting and conserving genetic resources.

Water Insecurity and Maternal Health Among Haudenosaunee Women in Canada.

Water is central to Haudenosaunee knowledge, philosophy, and culture. The health of Haudenosaunee mothers is tied to that of water. Today, the lack of access to reliable drinking water for Six Nations is a significant health concern. Technical measurement of water advisories in Canada fails to understand the interwoven relationship that Haudenosaunee women have with water. Highlighting the voices of 55 Haudenosaunee women, we provide expanded definitions of water insecurity and maternal health to include more-than-human beings. This comprehensive understanding of water insecurity and health shapes SN mothers' experiences with water in a settler colonial state, affecting their holistic wellbeing.

Amazonian Invertebrates in the Traditional diet of the Paiter Suruí in Southeastern Brazil.

The Paiter Suruí people in the southwestern Brazilian Amazon have a complex food system that includes insects and crustaceans. We designed our study to systematize data about the invertebrates they incorporate into their traditional diet. After conducting a review of the literature, we verified and expanded the data through semi-structured interviews with Paiter Suruí volunteers, and traced trends in their consumption of invertebrates. We identified 61 invertebrates, including 58 insects of the orders Coleoptera, Lepidoptera, Hymenoptera, and three crustaceans. While beetle larvae remain a popular choice, consumption of other insects and crustaceans seems to have diminished over time.

Socioecological effects of swidden management in traditional Maya agroforests in the Selva Lacandona of Chiapas, Mexico.

For millennia, Maya farmers (i.e., milperos) throughout Mesoamerica have managed milpa: sequential agroforests initiated by slashing and burning patches of secondary forest and then cultivating a diverse polyculture of trees and annual crops. To reduce greenhouse gas emissions associated with deforestation, the Mexican government and non-governmental organizations have urged milperos to cease burning. We collaborated with Maya milperos in several communities in the Montes Azules Biosphere Reserve region in Chiapas, Mexico to determine carbon retained as char in traditional milpas, carbon loss associated with burning, and effects of burning on soil quality. We found the carbon retention of char in Maya milpas (24 ± 6.5% of C in vegetation) is 4-1400% higher than other slash-and-burn agroecosystems reported in the literature. Burning resulted in significant carbon loss of 12.6 (±3.6) t C ha-1 yr-1, but this was partially mitigated by char production (3.0 [±0.6] t C ha-1 yr-1) and incomplete combustion of woody biomass. The effects of burning on soil were minimal, with the only significant changes observed being increases in pH, potassium availability, and cation exchange capacity (2, 100, and 7%, respectively). The mean residence times of charred materials were at least double that of uncharred biomass. While there is a risk that shortening fallow periods would undermine the sustainability of Maya swidden agroecology, proper management and secure land tenure can help maintain intensive production without enduring environmental degradation. The char produced in these swiddens and successional management could allow this agroforestry system to be a long-term carbon sink.

Plants and Other Materials Used for Dyeing in the Present Territory of Poland, Belarus and Ukraine according to Rostafinski's Questionnaire from 1883.

BACKGROUND: Traditional dyeing methods are practically forgotten in Poland. Józef Rostafinski included questions on the use of dyes in his ethnobotanical survey from 1883. METHODS: 126 questionnaires contained information on dye plants. They were identified by the respondents using folk names or sometimes even Latin names. Folk names were analyzed by comparison with other literature. Several voucher specimens were also present. RESULTS: 74 plant taxa were identified to genus or species level. The most commonly used were: onion (Allium cepa), brazilwood (Caesalpinia brasiliensis or Paubrasilia echinata), winter corn (mainly rye Secale cereale), black alder (Alnus glutinosa), safflower (Carthamus tinctorius), apple (Malus domestica), birch (Betula pendula), oak (Quercus robur), and violet flowering spring flowers (mainly Hepatica nobilis and Pulsatilla spp.). CONCLUSIONS: Most species are well known in the literature about plant dyeing, but the paper provides extra details on the picture of dyeing traditions in Eastern Europe.

Local and Traditional Ecological Knowledge of Fish Poisoning in Fiji.

Fish poisoning (FP) affects human health, trade and livelihood in Fiji, where management has depended mainly on traditional ecological knowledge (TEK). This paper investigated and documented this TEK through a 2-day stakeholder workshop, group consultation, in-depth interviews, field observations, and analyses of survey data from the Ministry of Fisheries, Fiji. Six TEK topics were identified and classified as preventative and treatment options. The preventive approach involves identifying toxic reef fishes, the spawning season of edible seaworms, hotspot areas of toxic fishes, folk tests, and locating and removing toxic organs. For example, 34 reef fish species were identified as toxic. The FP season was associated with the spawning of balolo (edible seaworm) and the warmer months of October to April (cyclone seasons). Two well-known toxic hotspots associated with an abundance of bulewa (soft coral) were identified. Folk tests and locating and removing toxic fish organs are also practised for moray eels and pufferfish. At the same time, various locally available herbal plants are used to treat FP as the second line of defence. The TEK collated in this work can help local authorities better identify the sources of toxicity, and applying TEK preventive measures could stem the tide of fish poisoning in Fiji.

Ethical principles of traditional Indigenous medicine to guide western psychedelic research and practice.

The resurgence of Western psychedelic research and practice has led to increasing concerns from many Indigenous Nations regarding cultural appropriation, lack of recognition of the sacred cultural positioning of these medicines, exclusionary practices in research and praxis, and patenting of traditional medicines. Indigenous voices and leadership have been notably absent from the Western psychedelic field currently widely represented by Westerners. An Indigenous-led globally represented group of practitioners, activists, scholars, lawyers, and human rights defenders came together with the purpose of formulating a set of ethical guidelines concerning traditional Indigenous medicines current use in Western psychedelic research and practice. A global Indigenous consensus process of knowledge-gathering was engaged which identified eight interconnected ethical principles, including: Reverence, Respect, Responsibility, Relevance, Regulation, Reparation, Restoration, and Reconciliation. A summary of the work is presented here with suggested ethical actions for moving forward within Western psychedelic research and practice spaces.
