1. Modelagem da Distribuição Potencial de Mangifera indica L. sob Cenários Climáticos Futuros no Bioma Caatinga
Resumo Mangifera indica L. (mangueira) é uma planta exótica invasora na região Nordeste do Brasil. No estado do Ceará sua presença merece particular atenção na área de Proteção Ambiental (APA) da Serra de Baturité (setor norte do Estado). O sinergismo da bioinvasão com o aquecimento do sistema climático somado ao parco conhecimento sobre a distr

2. Management priorities for exotic plants in an urban Atlantic Forest reserve
ABSTRACT Biological diversity is directly affected by alien species, even though the diagnosed impacts vary with scale. Early identification of the invasion of natural patches is essential for effective conservation actions. We aimed to determine the exotic plant species present inside Fontes do Ipiranga State Park (PEFI), an urban protected area located in

3. Forecasting the impact of an invasive macrophyte species in the littoral zone through aquatic insect species composition
ABSTRACT Invasive macrophytes threaten freshwater ecosystem biodiversity. We analyzed the impact of the invasive white ginger lily (Hedychium coronarium J. König, Zingiberaceae) on aquatic insect assemblages living in the littoral zone of a tropical reservoir. We took aquatic insect samples in the littoral zone on four main vegetal profile banks: white ging

4. Management techniques for the control of Melinis minutiflora P. Beauv. (molasses grass): ten years of research on an invasive grass species in the Brazilian Cerrado
ABSTRACT The invasion of exotic species is considered to be a major threat to the preservation of biodiversity. In the Parque Nacional de Brasília (National Park of Brasília), the invasive Melinis minutiflora (molasses grass) occupies more than 10 % of the area of the park. The present, long-term, study compared two treatments of exposure to molasses grass

5. Allelopathic suppression by Conyza canadensis depends on the interaction between latitude and the degree of the plant’s invasion
ABSTRACT Allelopathic suppression of the growth of co-occurring plant species in invaded ecosystems is an important factor in some plant invasions. This study uses leaf extracts of the invasive plant species Conyza canadensis to determine its allelopathic effects along a latitudinal gradient, and under different cover classes and degrees of invasion, on seed

6. 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

7. Impact of invasion by molasses grass (Melinis minutifloraP. Beauv.) on native species and on fires in areas of campo-cerrado in Brazil
In the Cerrado Biome of Brazil, African grasses constitute a serious problem, occurring in virtually all protected areas. Molasses grass (Melinis minutiflora P. Beauv.) accumulates more biomass than do most other species of the herbaceous stratum vegetation native to the Cerrado. In this study, our aim was to determine the impact of M. minutiflora on native

8. 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

9. Pericarp ontogenesis with emphasis on the dispersal apparatus of three weed species of Faboideae (Fabaceae)
It is known that the efficient dispersal is one among other features that amplify the invasion potential of a plant. Knowledge of the ontogeny, morphology and fruit dispersal of species is indispensable for weed control in crops. To identify the pericarp structures involved in the fragmentation and dehiscence processes and other features related to dispersal

10. Prevention of natural grassland invasion by Eragrostis plana Nees using ecological management practices
The objective of this research was to evaluate the effects of different types of disturbance on the ability of the natural grassland to avoid the invasion of Eragrostis plana Nees (South African lovegrass). The experiment was carried out in Dom Pedrito, Rio Grande do Sul, Brazil, in an area free of South African lovegrass, from Feb. 2004 to Apr. 2007. The tr

11. Effects of flooding and shading on growth and gas exchange of Vochysia divergens Pohl (Vochysiaceae) of invasive species in the Brazilian Pantanal
Vochysia divergens Pohl (commonly known as cambara) is a pioneer tree species that is native to the Amazon Basin but has been invading the seasonally flooded wetlands of the Brazilian Pantanal, forming monospecific communities. The physiological aspects associated with cambara invasion, including the effects of flooding and shading on growth and leaf gas exc

12. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion
