“…Several works have aimed to evaluate the benthic macroinvertebrate responses to different kinds of disturbances in wetlands. These studies suggest a broad variation of responses (Szalay & Resh 1997, Szalay & Cassidy 2001, Martin & Neely 2001, Kostecke et al 2005, Schmidt et al 2005, Rehage & Trexler 2006, Silveira et al 2011b. Benthic macroinvertebrates are a useful tool for environmental agencies (Rodrigues et al 2006), providing consistent information related to multiple sources of disturbance and response (Rosenberg & Resh 1992).…”

Abstract:Wetlands are important because they have high biodiversity and are considered, by environmental agencies, permanently protected areas due to their importance to conservation. In Southern Brazil the aquatic macrophyte Typha domingensis is harvested to be used in the manufacture of handicraft, being an important income source to small farmers. This work aims to test the cut effect of T. domingensis on benthic macroinvertebrates as well as on macrophyte regeneration. These phenomena were analyzed in small areas (1 m²) in a T. domingensis stand by comparing cut treatments and control treatments. Macroinvertebrate were sampled with a corer in the following time sequence after the cut event in both treatments: one day, 26 days, 60 days, 89 days, and 182 days. Macrophyte regeneration was monitored through monthly measurements at each treatment. The macroinvertebrate density did not differ between treatments (ANOVA, p < 0.05). Among the 23 taxa identified, Tubificidae was the only family to response to cut treatment. DCA showed an overlapping between treatments indicating a not clear pattern. The growth of T. domingensis shoots was not affected by the disturbance. Macrophyte regeneration was quick when comparing the treatments and statistical differences were found in one day after the disturbance and 26 days after the disturbance, whereas no differences were found in the remaining sampling dates (60, 89 and 182 days). Observing the macroinvertebrate response and the T. domingensis regeneration, our results suggest that sustainable use of this macrophyte is possible on a small scale.

Efeito do corte de Typha domingensis: resposta dos macroinvertebrados bentônicos e a regeneração da macrófita. Biota Neotrop. 12(3):http://www.biotaneotropica.org.br/v12n3/pt/abstract?article+bn03012032012Resumo: As áreas úmidas são importantes, pois apresentam alta biodiversidade e são consideradas pelos órgãos ambientais áreas de proteção permanente devido à sua importância para conservação. No Sul do Brasil a macrófita aquática Typha domingensis é colhida para ser usada na fabricação de artesanato, sendo uma fonte de renda importante para pequenos agricultores. Este trabalho teve como objetivo testar o efeito de corte de T. domingensis sobre os macroinvertebrados bentônicos, bem como sobre a regeneração da macrófita. Para avaliar o efeito do corte foram analisadas pequenas áreas (1 m²) em uma formação de T. domingensis onde comparou-se o tratamento de corte com tratamentos controle. Macroinvertebrados foram amostrados com um "corer" na seguinte sequência de tempo após o corte, em cada tratamento: um dia, 26 dias, 60 dias, 89 dias e 182 dias. A regeneração da macrófita foi monitorada através de medições mensais em cada tratamento. Não houveram diferenças significativas na densidade de macroinvertebrados entre os tratamentos (ANOVA, p < 0.05). Entre os 23 táxons i...

“…Totora is regarded as a valuable resource for some communities, and it has also been used in phytoremediation and marsh restoration throughout the Americas (Hester, Willis, & Sloey, 2016;Watson & Byrne, 2012). It has been reported that totora promotes a greater biodiversity than other emergent macrophytes and, when properly managed, can supply an important income source for the people that harvest it with a low impact or even a benefit to the environment (Hall, 2009;Lima Silveira, Gonçalves Rodrigues, Coelho de Souza, & Würdig, 2011;Sepúlveda-Mardones, López, & Vidal, 2017). Hence, some studies have assessed its management, planting methods, harvesting and potential economical returns (PELT, 2000b;Stevens & Hoag, 2003).…”

“…In fact, the lack of harvesting activities was identified as one of the causes of the nearly 44% reduction of the area covered by totora stands in Lake Titicaca, as mentioned earlier. As the harvesting of totora promotes re-growth and development of the plant (ABTEMA & UOB, 2000;PELT & ADESU, 2003), its use by the people could result in a symbiotic relationship by maintaining a desirable ecological equilibrium and generating income sources for the harvesters from the raw material commercialization (Lima Silveira et al, 2011).…”

“…Additionally, as explained by the weaver, this process helps to achieve a stiffer tissue because once the mat is finished, the stems recover some of their volume by swelling and stiffening the entire tissue. Esteras are the most widespread object among totora-working communities, with uses tracing back to thousands of years, and they are still used in many parts of the world (Bautista & Sánchez, 2015;Hall, 2009;Hidalgo C., 2015;Lima Silveira et al, 2011). Some studies have indicated that totora esteras seemed to be very valuable objects during the Inca empire, for there are records suggesting they were accepted as a form of tribute to the Inca due to their utility (Mardorf, 1985).…”
