RESUMO

Home gardens are considered germplasm repositories and places for experimentation, thus they are key sites for the domestication of plants. Domestication is considered a constant process that occurs along a continuum from wild to managed to domesticated populations. Management may lead to the modification of populations and in other cases to their distribution, changing population structure in a landscape. Our objective is focused on the management received in home gardens by perennial species of fruits. For this, the management practices applied to native and exotic perennial fruits species by a group of 20 women in the periurban zone of Iguazú, Argentina, were analyzed. In-depth interviews were conducted, as well as guided tours for the recognition and collection of specimens of species and ethnovarieties. Sixty-six fruit species managed in the home gardens were recorded. The predominant families are Rutaceae, Myrtaceae, and Rosaceae. The fruit species with the highest number of associated management practices are pitanga (Eugenia uniflora) and pindó (Syagrus rommanzoffiana). The 10 species with the highest management intensity are (in decreasing order of intensity) banana (Musa x paradisiaca), palta (Persea americana), pitanga (E. uniflora), mango (Mangifera indica), cocú (Allophylus edulis), mamón (Carica papaya), guayaba (Psidium guajava), limón mandarina (Citrus x taitensis), güembé (Philodendron bipinnatifidum), and mandarina (Citrus reticulata). Among the families with the greatest modifications in their distribution, abundance and presence of ethnovarieties in domestic gardens, are the native Myrtaceae and the exotic Rutaceae. The main management practices involved are cultivation, tolerance, transplant and enhancement in decreasing order. It can be concluded that in Iguazú, fruit species management shows both in plant germplasm as in environment a continuum that through tolerance, transplant and cultivation latu sensu has derived in a mosaic of species in different management situations, which in turn are representative of an anthropogenic landscape in constant domestication and change.

RESUMO

Numerous studies highlight the importance of phytotherapy for indigenous and non-indigenous people in different parts of the world. In this work we analyze the richness (number of species), diversity (plant identity and the number of illnesses for which it is used) and similarity of plant species and illnesses treated with them, in order to contribute new data and insight into the importance of plant medicines to the local medical systems of people living in Misiones province, in the subtropics of Argentina. Three sympatric groups were compared: Guarani Indians, Criollos (mestizos) and Polish migrants. Quantitative scrutiny was focused on both primary and secondary sources. The similarity and diversity of medicinal plants and uses between groups was calculated by applying the Sørensen quantitative coefficient and the Shannon-Wiener index, respectively. In order to identify the characteristic plant species used by each group, the Cultural Importance and Prevalence Value (CIPV) was calculated based on the species Indicator Value (IndVal), which combines a species relative abundance with its relative frequency of occurrence in the various groups, and modified according to the type of the analyzed data. The important finding is a great variation in the number of species used by the study groups. Altogether, 509 botanical species were registered: Guarani (397), Criollos (243) and Polish migrants (137). For all groups, the use of native medicinal plants prevailed. The Guarani appear to be the local experts in use of medicinal plants. There is the significant difference in the number of treated illnesses by each taxon among three groups. Criollos and Polish migrants exhibit the greatest similarity in illnesses treated with medicinal plants. These groups share a corpus of knowledge related to illness nosology, and have a symptomatic approach to illness treatment. The Guarani have an etiological approach to illness diagnosis and healing, which may be viewed as a barrier to the exchange of knowledge about home medicine with other ethnic groups of Misiones.

RESUMO

BACKGROUND: Not long ago Eugene Hunn suggested using a combination of cognitive, linguistic, ecological and evolutionary theories in order to account for the dynamic character of ethnoecology in the study of folk classification systems. In this way he intended to question certain homogeneity in folk classifications models and deepen in the analysis and interpretation of variability in folk classifications. This paper studies how a rural culturally mixed population of the Atlantic Forest of Misiones (Argentina) classified honey-producing stingless bees according to the linguistic, cognitive and ecological dimensions of folk classification. We also analyze the socio-ecological meaning of binomialization in naming and the meaning of general local variability in the appointment of stingless bees. METHODS: We used three different approaches: the classical approach developed by Brent Berlin which relies heavily on linguistic criteria, the approach developed by Eleonor Rosch which relies on psychological (cognitive) principles of categorization and finally we have captured the ecological dimension of folk classification in local narratives. For the second approximation, we developed ways of measuring the degree of prototypicality based on a total of 107 comparisons of the type "X is similar to Y" identified in personal narratives. RESULTS: Various logical and grouping strategies coexist and were identified as: graded of lateral linkage, hierarchical and functional. Similarity judgments among folk taxa resulted in an implicit logic of classification graded according to taxa's prototypicality. While there is a high agreement on naming stingless bees with monomial names, a considerable number of underrepresented binomial names and lack of names were observed. Two possible explanations about reported local naming variability are presented. CONCLUSIONS: We support the multidimensionality of folk classification systems. This confirms the specificity of local classification systems but also reflects the use of grouping strategies and mechanisms commonly observed in other cultural groups, such as the use of similarity judgments between more or less prototypical organisms. Also we support the idea that alternative naming results from a process of fragmentation of knowledge or incomplete transmission of knowledge. These processes lean on the facts that culturally based knowledge, on the one hand, and biologic knowledge of nature on the other, can be acquired through different learning pathways.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Analyzing how and why phytotherapeutical practices survive a migratory process is important for understanding migrant health seeking behaviour and health demand. Contrary to most studies, which focus on migrants from warm climates who settle in European and American cities, this study explores continuations in the herbal pharmacopoeia of Eastern European peasants who settled down in rural subtropical areas of Argentina. The study also explores the pharmacopoeia among the descendants of the first generation born in Argentina. MATERIAL AND METHODS: Primary and secondary sources were employed in the study. Data were collected during over 200 interviews (semi-structured, free lists and in-depth) with 94 study participants. Voucher specimens of species mentioned were gathered and identified. Illnesses were reported according to local ethnomedical terminology and classification. Only reports from informants' own experience were included in the analysis. The unit of analysis was a plant use report (plant species × plant part × ailment × informant). The frequency of mentions was calculated for plant parts used and modes of preparation and administration of herbal medicines, and the Informant Diversity Value was also estimated. Secondary information was obtained from ethnobotanical and ethnomedical literature concerning the whole of Poland. A list was made of medicinal plant species known from Poland available in the study area. Then, the similarity between the available species and those used by Polish migrants was evaluated by applying the Simpson index. RESULTS: An exhaustive list of 129 plant species used by the Polish community in Misiones, Argentina, was obtained. Among 37 species known form Poland and available in Misiones, 19 were used by the community. There was low consensus on the treatment of health conditions with legacy plants between Polish migrants and the Polish folk pharmacopoeia. The reasons for the relatively low use of legacy species are explained. More continuation has been observed in forms of application and administration of medicinal plants. Most of the continued species are food plants and are predominantly applied as medicinal food. CONCLUSIONS: In the migratory process, Polish peasants have preserved culturally salient species, which have a wide range of therapeutic applications and are easily accessible. Polish migrants and their descendants have incorporated a great number of local medicinal plant species into their home medicine but at the same time retained traditional ways of administration of herbal medicines. Based on the theory of acculturation, the observed patterns of medicinal plant use in Polish migrant colonies in Misiones indicate good adaptation to the predominant cultural environment.

RESUMO

This contribution presents information about the history of introduction, establishment, and local appropriation of Eurasian fruit trees-species and varieties of the genera Prunus and Citrus-from 15th century in two rural areas of Northern Argentina. By means of an ethnobotanical and ethnohistorical approach, our study was aimed at analysing how this process influenced local medicine and the design of cultural landscape that they are still part of. As a first step, local diversity, knowledge, and management practices of these fruit tree species were surveyed. In a second moment, medicinal properties attributed to them were documented. A historical literature was consulted referring to different aspects on introduction of peaches and citric species into America and their uses in the past. The appropriation of these fruit-trees gave place to new applications and a particular status for introduced species that are seen as identitary and contribute to the definition of the communities and daily life landscapes. Besides, these plants, introduced in a relatively short period and with written record, allow the researcher to understand and to design landscape domestication, as a multidimensional result of physical, social, and symbolic environment.

RESUMO

Farmers' decisions on what to grow and why can contribute in understanding the conservation of agrobiodiversity. Culture and ethnicity are indicated as first-class factors leading preservation of heirloom cultivars but this has been little considered in studies examining factors that influence the loss or preservation of agrobiodiversity. We propose that corn's ethnotaxa of less diverse uses, which are also key partners in local cultural reproduction, are usually cultivated by a few households. We analyse if there is a relationship between uses and richness of cultivated ethnotaxa at household level and describe corn's medicinal and ritual uses. We found 25 cultivated ethnotaxa, heterogeneously distributed in the region, and we also found that ethnotaxa with less diverse uses are cultivated in fewer households. We identified that, at regional scale, richness is related with food use diversity. The most frequently cited medicinal uses were urinary and tract infections, diarrhoea, and liver disorders. Medicinal recipes involve combinations with other elements. Maize is an indispensable resource in the rituals that propitiate productive activity, to augur prosperity or misfortune according to signals. We have identified the vulnerability in preserving the richness of corn in the region and the factors that shape its cultivation at different scales.

RESUMO

Honey-based mixtures used in home medicine by nonindigenous population of Misiones, Argentina. Medicinal mixtures are an underinvestigated issue in ethnomedical literature concerning Misiones, one of the most bioculturally diverse province of Argentina. The new culturally sensitive politics of the Provincial Health System is a response to cultural practices based on the medicinal use of plant and animal products in the home medicine of the local population. Honey-based medicinal formulas were investigated through interviews with 39 farmers of mixed cultural (Criollos) and Polish origins in northern Misiones. Fifty plant species and 8 animal products are employed in honey-based medicines. Plants are the most dominant and variable elements of mixtures. Most of the mixtures are food medicines. The role of honey in more than 90% of formulas is perceived as therapeutic. The ecological distribution of taxa and the cultural aspects of mixtures are discussed, particularly the European and American influences that have shaped the character of multispecies medicinal recipes.

RESUMO

BACKGROUND: Human beings employ a combination of morphological, sensorial, utilitarian, cultural and ecological characters when they identify and classify organisms. Ethnotaxonomy has provided a store of information about the characters cultures employ when they identify and classify a vast diversity of taxonomic groups. Nevertheless, some more research is needed to provide a comparison of the characters employed in the description of taxons, and an analysis of the extent to which those descriptors are represented. Stingless bees constitute a diverse group of social insects that have been widely studied from an ethnobiological perspective due to their utilitarian and cultural importance. The objective of this study is to identify the elements local people consider when characterizing stingless bees, and how important these elements are in the study of local classifications. METHODS: The methodology used involves semi-structured interviews and trips with the informants to rural areas. Locally known ethnospecies are characterized, descriptive traits and salient criteria used in those characterizations are identified, and the frequency of reference of descriptive traits and salient criteria are estimated. Besides, the descriptive traits used for each ethnospecies are compared, and the contribution of the characterizations as a heuristic strategy in the study of folk classification systems is analyzed. RESULTS: The use of 19 biological descriptors (grouped according to 4 salient criteria) and of comparisons among ethnospecies was found. Results suggest the existence of group and specific descriptors. Researchers identified which ethnospecies are considered similar, how less important traits contribute to descriptions, the relation between specific descriptors and ethnospecies, the presence of cognitive prototypes, and the most relevant salient properties from the emic perspective. CONCLUSIONS: The estimated importance of attributes descriptors allowed us to identify the spectrum of salient properties relevant from the emic perspective to characterize the stingless bees. In this sense, the analysis proposed here is useful to study folk taxonomy in culturally heterogeneous groups or multicultural regions, where the linguistic elements usually employed cannot be applied.

RESUMO

BACKGROUND: The state of conservation of the traditional cultures of Northwest Argentina is variable and somewhat problematic but to a lesser or a greater extent all the peoples are related to an hegemonic culture. We present a case study carried out in the rural communities of the Yungas biome (Salta) where the extent of isolation varies as does the type of access to public health services. The use of medicinal plants in the area is ordinary and widely spread. METHODS: The data can be organized in two categories, as medical systems public records (for the regional hospital at Los Toldos), and as ethnobotanical sets. A total of 59 surveys to 40 interviewees were undertaken using a semi structured questionnaire. We present an analysis of the relative importance of the medicinal herbs used in reproductive medicine considering the plants used in the traditional medical system and the factors that can affect the relationship between formal medicine and patients. We further analyzed how the degree of accessibility to the local hospital influences the diversity of use of plant species used to assist deliveries and to decrease infant mortality in children minor than one year of age. RESULTS: In reproductive medicine, 13 ailments and/or different physiological states are locally identified and treated. Local population uses 108 ethnospecies for this kind of illnesses. According to the local conception the hot/cold imbalance could be the principal cause for reproductive illnesses; pregnancy may have natural or supernatural origin, post partum and menstruation involve similar sanitary risks, and neonatal care has a strong magic connotation. In relation with the formal medicine, the more accessible is the health center the more women assist to it. We have not found a relation between accessibility and infant mortality. CONCLUSION: In the local reproductive medicine, most of the practices are concerned with the hot/cold balance. According to their importance the factors involved are: the family medicine, the midwife, and the formal doctors. Plants have an important role; however there is a lack of total agreement among the families who use them. Reluctance to institutional deliveries may be due to the weak relationship between patients and doctors, and the lack of logistic assistance to delivering mothers coming from far away locations.

RESUMO

En el presente artículo se analiza la vegetación del área delimitada por los ríos Saladillos de la Provincia de Santa Fe, Argentina. La región se ubica al sur del Chaco santafesino entre Arroyo el Toba y los ríos Saladillo al oeste del valle del río Panamá. El clima es cálido a templado, húmedo a subhúmedo. Haytres tipos de bosques, los "espinillares" de Acacia caven, los "algarrabales" de Prosopis spp. y los "quebrachales" de Schinopsis balansae, distribuidos siguiendo un gradiente geográfico. El aumento de espacies leñosas aumenta hacia el norte, y la estructura y estratisficación se hacen más complejas en esa dirección. Las comunidades herbáceas más importantes son los pajonales o sabanas de Spartina argentinesis y Panucum prionitis, junto con los otros pastos menos importantes. En las proximidades de las áreas inundadas por largos períodos o durante todo el año se encuentran juncales de Schoenoplectus californicus, totorales de Thypha domingesis, canutillares y vegas de distintas especies hidrófilas. Las comunidades se distribuyen siguente un gradiente edáfico de salinidad y humedad. El área puede ser considerada un Chaco empobrecido con una fuerte influencia del río Panamá
