Assim, notoriamente para paises em desenvolvimento e megadiversos, como o Brasil, o mais prudente seria a precaucoes contra a introducao de novas especies nao nativas e a tomada de acoes, estudos e manejo rapidos e eficientes no caso de invasoes ja relatadas. Infelizmente, o que temos visto e relatado, notoriamente por parte dos politicos e governantes no Brasil sao acoes rapidas e eficazes no sentido contrario (Magalhaes et al. 2011; Vitule et al. 2012 a e b).Literatura usada:Eisenhauer N, Scheu S, & Jousset A (2012) Bacterial diversity stabilizes community productivity.
