1. Enzymatic efficiency of the decomposing microbiota: what does really matter for aquatic macrophytes invasions?
ABSTRACT Biological invasions have negative impacts on different ecosystem-level functions, such as nutrient cycling. In aquatic environments, exotic litter can change the activity of the decomposer microbiota. We tested whether litter quality, litter decay, and enzyme activity differed between nativeEgeria densaand exoticHydrilla verticillata. The invasive

2. Can insect assemblages tell us something about the urban environment health?
Abstract Abstract: If we consider Drosophilidae, the answer to the question above is yes. Many research groups in Brazil and abroad have been showing that assemblages of flies of this family can reflect environmental alteration levels caused by urbanization, and/or by other human disturbances. I will present here a summary of our findings in Drosophilidae as

3. Invading the natural marine substrates: a case study with invertebrates in South Brazil
ABSTRACT The number of biological invasions has grown dramatically in recent decades, as well as the world's human population and coastal development. Anthropogenic habitats, such as pier pilings and break waters, have been constantly added to marine environment, usually concentrated in estuarine areas. These habitats are focal points for marine invasions, b

4. 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

5. Invasion impact by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) on a neotropical savanna
Whether management intervention is required to control biological invasions depends primarily on demonstrating species losses resulting from such invasions. Brackens of the Pteridium genus are currently regarded as a problem species that act as important ecological filters in the assembly of invaded communities. We investigated the effects of Pteridium arach

6. Red swamp crayfish: biology, ecology and invasion - an overview
ABSTRACTAlien species have been transported and traded by humans for many centuries. However, with the era of globalization, biological invasions have reached notable magnitudes. Currently, introduction of alien species is one of the major threats to biodiversity and ecosystem functioning. The North American crayfish Procambarus clarkii is one of the most wi

7. The effects of an exotic palm on a native palm during the first demographic stages: contributions to ecological management
Biological invasions have negative impacts on native biota and consequently on biodiversity. In patches of Atlantic Forest in Brazil, the Australian palm tree Archontophoenix cunninghamiana has become invasive, whereas the endemic palm Euterpe edulis is threatened with extinction. The two species occupy parts of the same functional niche within the forests,

8. Diet and trophic niche of Lithobates catesbeianus (Amphibia: Anura)
Lithobates catesbeianus (Shaw, 1802) is an invasive anuran introduced in Brazil that is associated with the displacement and the decline of populations of native species worldwide. There is evidence that biological invasions are facilitated by certain attributes of the invading species, for instance niche breath, and that invasive species have a broader ecol

9. Efeitos da arbórea introduzida Hovenia dulcis Thunb.(Rhamnaceae)sobre o componente árbóreo-arbustivo regenerante da floresta Atlântica no Sul do Brasil
Biological invasions by Hovenia dulcis Thunb., a tree from Asia, have been reported for Africa and South America. The present work aimed to evaluate the effects of the establishment of this exotic species on abundance, richness, species composition, growth, successional categories and beta diversity of natural regeneration in the Atlantic Rain Forest. Thus,

10. Comunidades de hidrozoários (Cnidaria) estuarinos do sudeste e sul do Brasil / Communities of stuarine hydrozoans (Cnidaria) from south and southeast of Brazil
The majority of the hydrozoans is marine, but they are also often recorded in estuaries. This environment is considered one of the most important in number of biological invasions. The Brazilian brackish hydrozoan fauna is practically unknown, except for some scattered records. The goals of this study are (1) to survey the planktonic and benthic hydrozoans f

11. Subsídios para o manejo da invasão biológica de uma palmeira em áreas de Mata Atlântica / Subsidies to ecological management of the biological invasion by a palm tree in Atlantic forest areas
The introduction of alien species in natural habitats resulting in processes of biological invasions is one of the indirect human actions which nowadays threaten global biodiversity. Although bioinvasions usually cause huge negative impacts in the native biota, they are still little studied in the megadiverse tropical environments. The Australian palm tree A

12. Ecologia populacional de Euterpe edulis e os efeitos da introdução de Euterpe oleracea na floresta atlântica no Estado de São Paulo
The main objectives of this dissertation were to evaluate the risks of introduction of Euterpe oleracea in the Atlantic Rainforest and its influence over a native population of Euterpe edulis. We investigated the ecological and morphological features of these species also including pre-existing data about hybrids experimentally produced between them (Chapter
