Importancia cultural de la flora empleada por la comunidad nativa Asheninka Sheremashe, Ucayali, Perú / Cultural importance of the flora used by the Asheninka Sheremashe native community, Ucayali, Peru

The cultural significance of the flora used by the native Asheninka Sheremashe community in Ucayali, Peru was determined. To do this, a fieldwork of over 4 months was conducted, involving semi-structured interviews with 106 residents through non-probabilistic convenience sampling. The community utilizes 139 plant species in their daily lives, belonging to 120 genera and 52 families, with the most abundant being Fabaceae, Arecaceae, Malvaceae, Solanaceae, Poaceae, and Rutaceae. Furthermore, 25.9% of the species are of significant importance to theinhabitants according to the Cultural Index (CI), such as Manihot esculenta, Theobroma cacao, Bixa orellana, Musa paradisiaca, Ficus insipida, among others. It can be concluded that the flora plays a prominent role in the life of the community, with the categories reporting the highest number of species being: food (29.35%), medicine (28.36%), culture (9.95%), construction (9.45%), lumber (6.97%), commerce (3.48%), craftsmanship (2.49%), toxic (2.49%), and other uses (7.46%)

Estudio etnobotánico de la flora medicinal de la provincia de Trujillo, Perú / Ethnobotanical study of the medicinal flora of the province of Trujillo, Peru

Trujillo, one of the main provinces of Peru, is home to a multicultural population, coming from the Coast, Sierra and Selva; of different ideologies, cultures, and ancestral knowledge about the correct use of medicinal flora. In this sense and in an effort to rescue this ancestral knowledge, the ethnobotanical study of the medicinal flora of the province of Trujillo was carried out. For which 96 semi - structured interviews were applied, using the "snowball" technique; followed by the collection, taxonomic determination and calculation of ethnobotanical indices: Use Value Index (IVU) and Informant Consensus Factor Index (FCI). It is concluded that the inhabitants of Trujillo make use of 102 species of medicinal flora, distributed in 95 genera and 46 families for the treatment and/or cure of 62 diseases. Of the total species, 24 turned out to be the most important (according to their IVU) for the cure of diseases of the Trujillo po pulation.

En tal sentido y en el afán de rescatar ese conocimiento ancestral, se realizó el estudio etnobotánico de la flora medicinal de la provincia de Trujill o. Para lo cual se aplicaron 96 entrevistas semiestructuradas, empleando la técnica "bola de nieve"; seguido de la colecta, determinación taxonómica y cálculo de Índices etnobotánicos: Índice de valor de Uso (IVU) e Índice de Factor de Consenso del Informa nte (FCI). Se concluye que los pobladores trujillanos hacen uso de 102 especies de flora medicinal, distribuidas en 95 géneros y 46 familias para el tratamiento y/o cura de 62 enfermedades. Del total de especies, 24 resultaron ser las más importantes (segú n su IVU) para la cura de enfermedades del poblador Trujillano.

Nematophagous Fungi: A Review of Their Phosphorus Solubilization Potential.

Nematophagous fungi (NF) are a group of diverse fungal genera that benefit plants. The aim of this review is to increase comprehension about the importance of nematophagous fungi and their role in phosphorus solubilization to favor its uptake in agricultural ecosystems. They use different mechanisms, such as acidification in the medium, organic acids production, and the secretion of enzymes and metabolites that promote the bioavailability of phosphorus for plants. This study summarizes the processes of solubilization, in addition to the mechanisms of action and use of NF on crops, evidencing the need to include innovative alternatives for the implementation of microbial resources in management plans. In addition, it provides information to help understand the effect of NF to make phosphorus available for plants, showing how these biological means promote phosphorus uptake, thus improving productivity and yield.

Valor de uso medicinal de la flora empleada por la Comunidad Andina de Jesús, Cajamarca, Perú / Medicinal use value of the flora used by the Andean Community of Jesús, Cajamarca, Peru

The medicinal flora plays a valuable role in improvingthe quality of life; ancestral knowledge that constitutes a legacy inherited by the Andean-Amazonian communities. The research was focused on determining the medicinal use value of the flora used by the Andean Community of Jesús. 96 semi-structured interviews were applied, using the "snowball" technique. The population of the Andean Community employs 84 species of flora, distributed in 80 genera and 45 families; where the Asteraceae, Lamiaceae, Rutaceae and Fabaceae were the most representative. Likewise, they suffer from 56 diseases, grouped into 11 categories, being the diseases of the Systems: respiratory (FCI=0.68), digestive and gastrointestinal (FCI=0.57), urinary (FCI=0.57), cardiovascular (FCI=0.56), reproductive (FCI=0.54) and Nervous (FCI=0.53), the most treated. Finally, the Andean Community attributes great importance to 54 species of medicinal flora; Therefore, it is urgent to implement projects and research that promote their sustainability.

Asimismo, padecen 56 enfermedades, agrupadas en 11 categorías, siendo las enfermedades de los Sistemas: respiratorio (FCI=0,68), digestivo y gastrointestinal (FCI=0,57), urinario (FCI=0,57), cardiovascular (FCI= 0,56), reproductivo (FCI=0,54) y Nervioso (FCI=0,53), las mayormente tratadas. Finalmente, la Comunidad Andina atribuye gran importancia a 54 especies de flora medicinal; por lo que urge implementar proyectos e investigaciones que fomenten la sustentabilidad de las mismas.

Preserving Traditional Botanical Knowledge: The Importance of Phytogeographic and Ethnobotanical Inventory of Peruvian Dye Plants.

Abstract: Peru is a megadiverse country with native species of all kinds, including dye plants, which have been used for hundreds of years by the local population. Despite the fact that many of these natural dyes are of a superior quality compared to synthetic ones and do not have the harmful effects that the latter may cause to human health, due to the lack of documentation and dissemination, ethnobotanical knowledge is unfortunately being lost with the passing of generations. In order to preserve and spread such valuable knowledge, this study conducted a comprehensive taxonomic, phytogeographic, and ethnobotanical inventory of dye plants based on periodical botanical explorations in selected locations of Northern Peru during the span of two decades. A critical review of the specialized bibliography was then carried out and the findings were verified with the personal knowledge and experience of both the researchers and the local and regional people. The results of the inventory record 32 species of dye plants from Northern Peru distributed in 22 families, of which the following stand out due to the number of species: Fabaceae (5), Anacardiaceae (2), Annonaceae (2), Asteraceae (2), Berberidaceae (2), Rosaceae (2), and Solanaceae (2). Of the 32 dye species identified, four are considered endemic from Peru: Berberisbuceronis J.F. Macbr., Caesalpiniapaipai Ruiz & Pav., Coreopsissenaria S.F. Blake & Sherf., and Lomatiahirsuta (Lam.) Diels. The study also found that species such as Bixaorellana L., Indigoferasuffruticosa Mill., Sambucusperuviana, and the lichen Usneabaileyi (Stirton) Zahlbr have not been commercially exploited in Peru despite the fact that they already constitute a great economic source for several countries.
