A genética contra os crimes ambientais

Abstract: A perda acelerada da cobertura vegetal coloca em risco os recursos naturais e a diversidade biológica, além de afetar a produtividade econômica. Atualmente, a despeito da fiscalização para coibir a prática, grande parte dos desmatamentos são feitos de forma ilegal. Para auxiliar o ensino de Genética da Conservação e Ecologia Molecular é proposta uma atividade que demonstra como o uso de marcador molecular, baseado no sequenciamento de DNA de cloroplasto, pode auxiliar na identificação de amostras apreendidas p… Show more

“…Among the several techniques are highlighted the traditional recognition of tree species using wood macroscopic images (Yusof et al, 2013;Zhao 2013;Zhao et al, 2014;Paula-Filho et al, 2014;Ravidran et al, 2018;Souza et al, 2020;Fabijanska et al, 2021;Gonçalves et al, 2022) and microscopic images (Mallik et al, 2011;Gurau et al, 2013;Guang-Sheng and Peng 2013). Other methodologies are mentioned, like the molecular markers or DNA Barcoding (Miranda et al, 2014;Yu et al, 2015;Jiao et al, 2020), NIR spectroscopy (Monteiro et al, 2010;Soares et al, 2017); chemometric processing of direct analysis (DART-TOFMS) and mass spectrometry-derived fingerprints (Musah et al, 2015;Evans et al, 2017;Ravindran and Wiedenhoeft, 2020;Price et al, 2021;Kitin et al, 2021). However, these promising technologies of tree species identification applying wood anatomy with aim to improve the wood trade traceability have the high cost of sample processing, expensive equipments and specialized personal.…”
