“…We formulated them in culturally appropriated and meaningful ways, using concepts that were not foreign to the cultural system of meaning. We also tested the questionnaire in each area during a pilot survey (Luoga et al 2000) to ensure that interpreters, respondents and we correctly understood the questions. This process allowed us to limit information distortion through translation.…”

Research AbstractIntegrating ethnobotanical knowledge in the development of management and conservation strategies of indigenous plant resources is critical to their effectiveness. In this paper, we used four plant use indices to assess how the plant use knowledge of a multipurpose tree (Pentadesma butyracea Sabine) varies across different sociolinguistic groups from two geographical areas of Benin, and how these variations may influence the species' conservation and utilisation strategies. Seven sociolinguistic groups namely the Anii, Nagot, Kotocoli, and Fulani in the central part, and the Waama, Ditamari and Natimba in the northwestern part of the country were considered. We determined the reported use value of the plant parts, the plant part value, the specific use and the intraspecific use value for each sociolinguistic group. The various communities showed different interests in the plant organs they used. Nagot people showed the best plant use knowledge (highest use value) for P. butyracea bark and roots, two organs critical to the plant survival. Sociolinguistic groups living in the same geographical area shared similar plant part values, likely because of knowledge exchanges through social interactions. The observed intercultural convergences of uses may be a starting point of the selection of parts of the species for phytochemical, biological and pharmacological studies.

“…The relationship between humans and plant resources has been investigated by ethnobotany not only in the Caatinga, but in many parts of the world (Hanazaki et al 2006, La Torre-Cuadros & Islebe 2003, Luoga et al 2000, Reyes-García et al 2005, Shanley & Rosa 2004. The first ethnobotanical studies documented knowledge that traditional populations retained about their biodiversity.…”

“…The first ethnobotanical studies documented knowledge that traditional populations retained about their biodiversity. Inthe 1990s, there was an increase in this research field at the time statistical tests, quantitative indexes, and hypothesis tests were adopted in investigations (Ferraz et al 2005, Hanazaki et al 2006, La Torre-Cuadros & Islebe 2003, Lucena et al 2007, Luoga et al 2000, Oliveira et al 2010, Phillips & Gentry 1993a, 1993b, Ramos et al 2008a, 2008b, Ribeiro et al 2014a, 2014b, Shanley & Rosa 2004. Standing out in this context are the use value index and the ecological apparency hypothesis.…”

The ecological apparency hypothesis seeks to understand the dynamics of use that a particular species has through its availability in vegetation areas. According to this hypothesis, apparent plants are the most collected and used by humans. This hypothesis was tested in the rural community of Santa Rita, municipality of Congo, in Cariri microregion (Paraíba state, Northeast Brazil). We calculated the use value (UV) for each species. For the phytosociological inventory, we adopted the point-quadrant method, plotting 500 points distributed in the vegetation areas of the community, registering the perimeter measurements and height of 2000 plants. Interviews were conducted with householders, totaling 98 informants (41 men and 57 women), and 24 species, 21 genera, and 11 families were recorded. The cited species were grouped into 11 utility categories. The Spearman correlation coefficient was used to correlate phytosociological and ethnobotanical data. The use values of the species did not correlate with phytosociological parameters. Regarding the use categories, there were positive correlations for fuel (UV with dominance and basal area), construction (UV with all phytosociological parameters), fodder (UV with all parameters), and poison/abortion categories (UV with density and frequency). Ecological apparency significantly explained the local importance of useful plants in fuel, construction, and fodder categories, and less significantly for poison/abortion.

“…Some studies evaluated species use-value for local populations, for showing which plants are preferred for each population (Phillips & Gentry, 1993b, Galeano, 2000, Crepaldi & Peixoto, 2010. Studies also related use-values with species availability in their natural ecosystems (Phillips & Gentry, 1993b, Torres-Cuadro & Islebe, 2003, Ferraz, Albuquerque, & Meunier, 2006, testing the hypothesis of the ecological appearance (Phillips & Gentry, 1993b) and making possible to identify over-exploration of plants (Luoga, Witkowski, & Balkwill, 2000). However, Phillips and Gentry (1993b) calculated the use-values index based in the knowledge of local informants about useful species (potential utilization value) and Lucena et al (2013) adapted this index, using the frequency of collection of the vegetation species by local informants (real utilization value).…”

ABSTRACT. Ethnobotanical studies involve research with human societies and their different interaction with plants, and the quantitative approaches from thes estudies are important to select conservation priority of species in natural environment. This research aims to quantify use-values for woody plants mentioned by fishers in Itaúnas, state of Espírito Santo, and evaluate the relationship between use-values and species availability (absolute density and frequency, and importance value) in two distinct resting vegetation formations. It also proposes to identify priority species for conservation. It was selected 30 species cited in individual semi-structured interviews with key-informant in fishers' community and who were also on list of structural survey of two vegetation phytophysiognomies in the restinga regions. The data used was collected in previously published work. It was performed a correlation analysis between use-values and structural parameters of the mentioned woody species. Protium heptaphyllum, P. icicariba and Byrsonima sericea present the highest use-values. It was not observed relation between use-value and species availability in each vegetation formation. It was classified two and eight species as priority for conservation on shrubby and forest formations, respectively.Keywords: structural characteristics, ethnobotany, Itaúnas State Park, restinga, use-value (UV).Espécies lenhosas úteis e sua disponibilidade no ambiente: o caso dos pescadores artesanais em Itaúnas, Brasil RESUMO. Estudos etnobotânicos envolvem pesquisas com sociedades humanas e suas diferentes interações com as plantas, e abordagens quantitativas deste estudos são importantes para selecionar prioridades de conservação das espécies nos ambientes naturais. Esta pesquisa objetiva quantificar os valores de uso das plantas citadas por pescadores em Itaúnas, Espírito Santo, e avaliar as relações entre os valores de uso a disponibilidade das espécies (densidade e frequência absoluta e valor de importância) em duas formações vegetais distintas de restinga. É também proposto identificar o índice de prioridade de conservação das espécies. Foram selecionadas 30 espécies citadas em entrevistas individuais semiestruturadas com informantes-chave na comunidade de pescadores e que também estavam em listas de levantamentos estruturais de duas fitofisionomias vegetais de restinga na região. Os dados utilizados foram coletados em trabalhos previamente publicados. Foi feita a análise de correlação entre os valores de uso e os parâmetros estruturais das espécies lenhosas mencionadas. Protium heptaphyllum, P. icicariba e Byrsonima sericea apresentaram o maior valor de uso. Não foi observado relação entre o valor de uso a disponibilidade das espécies em cada formação vegetal. Foram classificadas duas e oito espécies para prioridade de conservação nas formações arbustivas e florestais respectivamente.Palavras-chave: características estruturais, etnobotânica, Parque Estadual de Itaúnas, restinga, valor de uso.
