“…In the 1990s, Piperno (1990) considers phytolith analysis as sufficiently mature to provide source of data in tropical paleoethnobotany and paleoecology independent from archaeology. A review of recent studies (Bertoldo, Paisani & Oliveira 2014;Bremond et al, 2005;Calegari 2017;Calegari, Raitz & Paisani 2011;Luz et al, 2015;Piperno 1990Piperno , 2006Ramirez et al, 2019) shows that phytolith analysis brings major contributions to research on the distribution and composition of past plant communities in contact with humans.…”

“…We described phytoliths according to their three-dimensional shape and classified them following the international phytolith nomenclature code (Madella et al, 2005). We calculated three phytolith indices for each sample.…”

“…Studies on phytoliths in Brazil are still incipient (Luz et al, 2015), but there is relevant information about different Brazilian biomes. In peat bogs of a mixed rainforest in the state of Paraná, southern Brazil, Rasbold et al (2016) recognized drier climatic conditions 14,500 years ago, with a gradual increase in humidity starting 6000 years ago.…”

“…A origem e fases de desenvolvimento de fitólitos nos vegetais, podem estar relacionados a vários fatores, incluindo: tipo de solo; idade da planta; ambiente climático de crescimento; quantidade de água no solo e, o mais relevante para este tipo de análise, afinidade taxonômica para a produção de fitólitos. As razões da produção de fitólitos pelas plantas também são poucos conhecidas, porém, Luz et al (2015) destaca ao menos quatro possibilidades: Oferecer suporte mecânico para a estrutura das células; dar suporte aos órgãos e estruturas da planta; proteger a planta de herbívoros e parasitas; e neutralizar ânions e cátions nocivos ao desenvolvimento das plantas. (MADELLA, 2005) Existem alguns protocolos que são utilizados para extração de fitólitos após a coleta das amostras da cobertura superficial em campo, destaca-se Alvarez et al (2005) e Calegari et al (2013).…”
