13. Could biological invasion by Cryptostegia madagascariensis alter the composition of the arbuscular mycorrhizal fungal community in semi-arid Brazil?
Biological invasions pose a serious threat to native semi-arid areas of Brazil, especially in areas of the state of Ceará that are typically invaded byCryptostegia madagascariensis, an exotic plant species from Madagascar. However, how this biological invasion influences the composition of the arbuscular mycorrhizal fungal (AMF) community and how this affec

14. Ecophysiological leaf traits of native and exotic palm tree species under semi-arid conditions
ABSTRACT The main goal of this study was to evaluate the performance of two palm species under semi-arid conditions during the rainy and dry periods: the semi-arid native Syagrus coronata and a native to tropical America, Acrocomia aculeata. The leaf water potential, gas exchange, leaf soluble sugars, starch, free amino acids, total soluble protein content a

15. Potencial do latex da fruta pão (Artocarpus altilis) como agente coagulante do leite
Breadfruit is an exotic tree in Brazil, very well acclimatized. Despite of being a laticifer plant, the knowledge about its latex is scarce. However, it is known that proteolytic enzymes represents over 50% of the latex composition in laticifers plants. The aim of this study was to evaluate the potential of breadfruit (Artocarpus altilis var. Apyrena) latex

16. Litter traits and palatability to detritivores: a case study across bio-geographical boundaries
The activity of the litter-feeding macrofauna affects litter decomposition rates at the local scale, and their preference for particular litter types is mediated by litter traits. Environmental changes such as invasion by exotic plants may change the characteristics of the litter at a local scale, with consequences to ecosystem processes. Here we evaluated t

17. What is the role of exotic medicinal plants in local medical systems? A study from the perspective of utilitarian redundancy
Medicinal plants are an important aspect of local medical systems. The composition of a medicinal plant collection is influenced by cultural and environmental factors. Additionally, the functionality of a local medical system can be threatened by the replacement of native species with exotic ones, as well as by cultural factors such as the erosion of knowled

18. Women's ethnomedicinal knowledge in the rural community of São José da Figueira, Durandé, Minas Gerais, Brazil
São José da Figueira is a rural community which economy is based on small-sized family-owned agricultural and dairy farms. Rural communities often possess medicinal plant knowledge because not only does the rural lifestyle promote this but also because these communities coexist with a wide variety of plants. The aim of this study was to survey the knowledg

19. Fatos e tendências da biocatálise
Brazil is renowned for its biodiversity; however, its economy is based on exotic plants, extraction and unsustainable use of natural resources. This issue was addressed in a recent QN review entitled "Chemistry without Borders." In order to explore the potential of Brazilian biodiversity fully, sustainable development is required in key technological areas,

20. Métodosdesuperaçãodedormênciadesementesde Flamboyant / Methods of overcoming seed dormancy flamboyant
The Flamboyant (Delonix regia (Bojer ex Hook) Raf.) is an exotic ornamental species adapted to the conditions of the Brazilian territory, belonging to subfamily Caesalpinioideae and it has seeds with hard coat that promotes seed dormancy caused by the impermeability of seed coat to water and oxygen. The aim of this study was to test different types of mechan

21. Diversidade genética de Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) e caracterização molecular das linhagens de Wolbachia associadas / Genetic diversity of Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) and molecular characterization of the associate strains of Wolbachia
Diaphorina citri Kuwayama, 1908 (Hemiptera: Psyllidae) is an exotic insect in Brazil, first recorded in the 40s. Although it causes direct damage, D. citri only received attention as a pest in 2004, when the \"Huanglonbing\" (HLB) disease was confirmed infecting citrus in Brazil, and subsequently related to D. citri as vector. Currently, there is no cure for

22. Molecular characterization of the polyphenol oxidase gene in lulo (Solanum quitoense Lam.) var. Castilla
Lulo (Solanum quitoense Lam.) is an exotic fruit from the Andes Mountains with a high export potential. However, the browning that is produced during harvest and the postharvest processes alters the organoleptic and nutritional properties of this fruit, which has made its management as a fresh fruit difficult. The browning processes are regulated by the enzy

23. PLANTAS EXÓTICAS NA APA DO LAGAMAR DO CAUÍPE-CE / EXOTIC PLANTS IN THE APA LAGAMAR Do Cauípe-EC
Espécies vegetais exóticas invasoras são consideradas a segunda causa da perda da biodiversidade no mundo, ficando atrás apenas pela exploração humana direta. Em Unidades de Conservação a presença delas é extremamente prejudicial porque as mudanças por elas causadas ao ambiente podem levar à extinção de espécies nativas e a conseqüentemente p

24. Diversidade de macrófitas aquáticas em áreas úmidas do Parque Nacional da Lagoa do Peixe, Rio Grande do Sul
The Lagoa do Peixe National Park is an important conservation unity, aiming to protect the wetlands, one of the most endangered type of ecosystem in the world. In Southern Brazil around 90% of the wetlands were already lost. The protected ecosystems in the park are ernationally important for biodiversity conservation and it is the unique Ramsar site in South
