AbstractHerbivores may facilitate or impede exotic plant invasion, depending on their direct and indirect interactions with exotic plants relative to co-occurring natives. However, previous studies investigating direct effects have mostly used pairwise native-exotic comparisons with few enemies, reached conflicting conclusions, and largely overlooked indirect interactions such as apparent competition. Here, we ask whether native and exotic plants differ in their interactions with invertebrate herbivores. We manipulate and measure plant-herbivore and plant-soil biota interactions in 160 experimental mesocosm communities to test several invasion hypotheses. We find that compared with natives, exotic plants support higher herbivore diversity and biomass, and experience larger proportional biomass reductions from herbivory, regardless of whether specialist soil biota are present. Yet, exotics consistently dominate community biomass, likely due to their fast growth rates rather than strong potential to exert apparent competition on neighbors. We conclude that polyphagous invertebrate herbivores are unlikely to play significant direct or indirect roles in mediating plant invasions, especially for fast-growing exotic plants.

Resumo: Para analisar a legislação para fitoterápicos no Brasil e as mudanças propostas com o Projeto de Lei n.o 3381/2004, que tenta modernizá-la, foi utilizado o Delphi Eletrônico, que busca o consenso de opiniões entre especialistas na área. Assim, foram aplicados 100 questionários e, a partir dos resultados, foi possível constatar que a atual legislação é uma das maiores barreiras do setor, devido às exigências e altos custos com pesquisas, assim como a falta de estudo sobre as plantas nativas, o que privilegia a entrada de plantas exóticas no país. A falta de informação, descrédito e desconfiança dos profissionais prescritores, também, têm prejudicado o setor. A pesquisa conclui, portanto, que se o Projeto de Lei for aprovado, trará mudanças positivas como: influência no comportamento das indústrias brasileiras, aumentando sua produção; alteração na localização geográfica das indústrias deste setor, causando a descentralização; aumento na utilização de plantas nativas que, consequentemente, ocasionará a diminuição nos níveis de importação.Palavras-chave: Plantas Medicinais, fitoterápicos, legislação.EVALUATION OF THE REGULATORY MARK IN THE PRODUCTION OF PHYTOTHERAPEUTIC MEDICINES IN BRAZILAbstract: To analyze the legislation of phytotherapeutic in Brazil and the changes proposed by the Law Project 3381/2004, that tempts to modernize it, was utilized the Electronic Delphi, that looks for opinion consensus among specialists of the area. Therefore, one hundred questionnaires were applied and the results discovered that the current legislation is one of the biggest limits to the production chain, due to the exigencies and high costs with researches, as well as the lack of study about native herbs, that makes easier the entrance of exotic plants in the country. The lack of information, discredit and suspicion of the prescriber professionals, also, have prejudiced of the area. Concludes that if the Law Project comes to be approved, it will bring positive changes like: influence in the behavior of Brazilian industries, increasing its production; change of geographical place of the industries of this sector, causing decentralization; improve the use of native herbs that, consequently will cause a decrease in the importation levels.Key words: Medicinal plants, phytotherapeutics, legislation.
