Diversidade inter- e intra-específica e uso de análise multivariada para morfologia da mandioca (Manihot esculenta Crantz): um estudo de caso 63
Peroni,Nivaldo; Martins,Paulo Sodero; Ando,Akihiko.
A agricultura itinerante, caracterizada por ciclos de uso e pousio, é uma técnica utilizada por muitos agricultores no mundo, assim como por agricultores tradicionais da região de Cananéia (SP). Estes agricultores herdaram toda um gama de conhecimentos transmitidos oralmente sobre a agricultura praticada por povos indígenas desde o período pré colonial. A mandioca é o principal cultivo neste sistema, o que a torna um organismo chave para entender as especificidades do sistema agrícola itinerante. Foram obtidas informações sobre as espécies cultivadas no sistema itinerante, e mais especificamente sobre as etnovariedades de mandioca. Entrevistas com os agricultores permitiram caracterizar o sistema utilizado, demonstrando que na propriedade estudada podem...

Genetic diversity in Brazilian sweet potato (Ipomoea batatas (L.) Lam., Solanales, Convolvulaceae) landraces assessed with microsatellite markers 74
Veasey,Elizabeth Ann; Borges,Aline; Rosa,Mariana Silva; Queiroz-Silva,Jurema R.; Bressan,Eduardo de Andrade; Peroni,Nivaldo.
We used simple sequence repeat (SSR) markers to investigate the genetic diversity of 78 sweet potato (Ipomoea batatas) accessions (58 landraces and 20 putative clones) from traditional agricultural households from 19 local communities in the Vale do Ribeira, São Paulo, Brazil. Eight SSR loci were assessed using 6% (w/v) polyacrylamide gels stained with silver nitrate and the accessions genotyped considering the presence or absence of bands. The results were subjected to analysis of molecular variance (AMOVA), and cluster and principal coordinate analyses. Spatial structure was assessed using Mantel's test to compare genetic and geographic distances. Each primer pair generated between three and ten clearly scorable polymorphic fragments. Cluster analyses...

High genetic diversity among and within bitter manioc varieties cultivated in different soil types in Central Amazonia 74
Alves-Pereira,Alessandro; Peroni,Nivaldo; Cavallari,Marcelo Mattos; Lemes,Maristerra R.; Zucchi,Maria Imaculada; Clement,Charles R..
Abstract Although manioc is well adapted to nutrient-poor Oxisols of Amazonia, ethnobotanical observations show that bitter manioc is also frequently cultivated in the highly fertile soils of the floodplains and Amazonian dark earths (ADE) along the middle Madeira River. Because different sets of varieties are grown in each soil type, and there are agronomic similarities between ADE and floodplain varieties, it was hypothesized that varieties grown in ADE and floodplain were more closely related to each other than either is to varieties grown in Oxisols. We tested this hypothesis evaluating the intra-varietal genetic diversity and the genetic relationships among manioc varieties commonly cultivated in Oxisols, ADE and floodplain soils. Genetic results did...

How are legal matters related to the access of traditional knowledge being considered in the scope of ethnobotany publications in Brazil? 39
Liporacci,Heitor Suriano Nascimento; Miranda,Tatiana Mota; Hanazaki,Natalia; Peroni,Nivaldo.
Legal measures, such as the use of free or prior and informed consent, return of research results to communities (which can be understood as "sharing of benefits," according to Brazilian legislation), and research authorization by governmental bodies, are mentioned and regulated in various documents, either governmental or specific, within the area of ethnobiology. This study aims to explore how these matters are considered in the scope of published ethnobotany articles in Brazil, as well as whether the creation of the Provisional Measure 2.186-16/2001 has contributed to the national advance of these matters. The methodology comprised a literature review of articles focusing on medicinal and food plant resources in the prominent Brazilian journals which...

Limitações ao uso de espécies florestais nativas pode contribuir com a erosão do conhecimento ecológico tradicional e local de agricultores familiares 39
Zuchiwschi,Elaine; Fantini,Alfredo Celso; Alves,Antonio Carlos; Peroni,Nivaldo.
O conhecimento ecológico tradicional ou local é construído a partir da relação contínua de humanos com o meio ambiente, principalmente pelo uso cotidiano das espécies. O abandono do uso, por sua vez, pode provocar perda desse tipo de conhecimento, o que freqüentemente decorre de mudanças no modo de vida. Neste trabalho buscou-se avaliar o conhecimento e o uso efetivo, atual e passado, de espécies vegetais das Florestas Estacional Decidual e Ombrófila Mista por agricultores familiares da região Oeste de Santa Catarina. Os métodos de coleta e análise de dados basearam-se numa integração de métodos qualitativos e quantitativos em Etnobotânica. Os resultados revelaram que esses agricultores possuem um amplo conhecimento a respeito das espécies florestais...

Local knowledge of medicinal plants in three artisanal fishing communities (Itapoá, Southern Brazil), according to gender, age, and urbanization 39
Merétika,Adriana Heindrickson Cunha; Peroni,Nivaldo; Hanazaki,Natalia.
This article analyzes some of the factors affecting the distribution of knowledge about medicinal plants of three artisanal fishing communities in Itapoá Municipality, in the state of Santa Catarina, Brazil. Ninety semi-structured interviews were performed, which resulted in 109 cited plant species. The sample included both men (n=46) and women (n=44), in different age categories: 18-40 years old (n=18), 41-50 (n=21), 51-60 (n=28), and 61+ years old (n=23), and in three different communities: Barra do Saí (n=17), Itapema do Norte (n=31) and Pontal do Norte (n=42). Leaves are the plant parts most used by the communities (62%), and are obtained primarily through cultivation. Cordia curassavica (Jacq.) Roem. & Schult. (Boraginaceae) is the species...

Population structure and fruit availability of the babassu palm ( Attalea speciosa Mart. ex Spreng) in human-dominated landscapes of the Northeast Region of Brazil 39
Campos,Juliana Loureiro Almeida; Albuquerque,Ulysses Paulino; Peroni,Nivaldo; Araújo,Elcida de Lima.
ABSTRACT We studied the population structure and fruit availability of the babassu palm, Attalea speciosa, in three human-dominated landscapes located near a rural community in the region of Araripe, in the Northeast Region of Brazil, that were under intense fruit harvest. Fifty 10 x 10 m plots were randomly established in each of the three landscapes, and all individuals of A. speciosa within the plots were classified as seedlings, juveniles or adults, with the height of all adult individuals being measured. An additional 20 individuals were marked in each landscape, and the number of total bunches, fruits per bunch and bunches per palm tree were recorded. The populations of A. speciosa in the three landscapes exhibited an inverted J-shape plot, but...

Species diversity, community structure and ecological traits of trees in an upper montane forest, southern Brazil 39
Sühs,Rafael Barbizan; Hoeltgebaum,Marcia Patricia; Nuernberg-Silva,Anelise; Fiaschi,Pedro; Neckel-Oliveira,Selvino; Peroni,Nivaldo.
ABSTRACT Upper montane ecosystems in Brazil are little known, and their structural and functional aspects poorly understood. Our goals were to describe tree species diversity and community structure, and to characterize tree species in relation to their ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest remnant. A total of 26 species belonging to 18 families were found in a 1-hectare permanent plot. The tree community mainly comprised trees with diameters of less than 20 cm and heights of between 6.5 and 9.5 m. Drimys angustifolia and Myrceugenia regnelliana had the highest importance values. Most species were shade tolerant while most individuals were pioneers. Most species and individuals presented...
