Aquatic vascular plants as handicraft: a case study in southern Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Báez-Lizarazo,Mabel R.; Santoro,Flavia Rosa; Albuquerque,Ulysses Paulino; Ritter,Mara Rejane.
ABSTRACT This study aimed to evaluate knowledge about and the usage and importance of aquatic vascular plants (AVPs) in the production of handicrafts by communities on the north coast of the state of Rio Grande do Sul in southern Brazil. The snowball technique was employed to locate people who use and have knowledge regarding the use of AVPs for handicrafts. Data were collected through semi-structured interviews and guided tours with 35 interviewees who were involved in artisanal activity at the time of the study. The data were analyzed using the importance value (IV) index and the consensus value for the forms of use (CMU). The Spearman correlation test (rs) was employed to determine the correlations of each social variable with the knowledge variables,...

Lagoons are considered protected areas because these systems play a key ecological role. However, the extraction of macrophyte Schoenoplectus californicus is held for manufacture of handcrafts, being an alternative income for riverbank communities. This study evaluated the impact of S. californicus experimental cutting on benthic macroinvertebrates trough a field experiment. Macroinvertebrates were sampled at 1, 12, 26 and 60 days after the macrophyte cutting in demarked plots (1 m²), as well at control plots. The families number was not statistically different (ANOVA, p &gt; 0.05), but the total density of invertebrates, and the density of Ceratopogonidae were significant (ANOVA, p &lt; 0.05) for interaction between sampling date and treatment. A...

ABSTRACT: Brazil continues to use wood as the principal raw material source for the pulp industry; although, non-wood fibers have been revealed to be a competent substitute to produce paper with different and exceptional properties. Keeping this in focus, this study aimed to assess potential of Schoenoplectus californicus fibers (C. A. Mey.) Soják, commonly identified as bulrush or reed, in cellulosic pulp generation, as an alternative fiber source for the pulp and paper industry. On analyzing the chemical composition of reed fibers, extractives of lignin, carbohydrates, uronic acids and minerals were reported. Physico-chemical characteristics of reed-based cellulosic pulp were estimated including viscosity, hexenuronic acids, etc., as well as anatomical...
