1. Response of rhizomes of the invasive Hedychium coronarium J. König (Zingiberaceae) to different soil moisture conditions
ABSTRACT The ability to maintain high competitiveness under a wide range of conditions is common among successful invasive species. The performance of rhizomatous macrophytes in different habitats is closely related to morphological and physiological adaptations in the rhizome system. We investigated the effects of soil moisture conditions on the microstruct

2. Use of osmoregulatory ability to predict invasiveness of the Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) an invader in Southern Brazil
Abstract The Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) is native to the Indo-Pacific Ocean, and occurs as an invasive species along the Eastern American coast, where it was probably introduced in ballast water. The present study evaluated the osmoregulation and salinity tolerance of C. hellerii in Paranaguá Bay, Paraná, Brazil,

3. Lonchaeidae (Diptera) species and their host plants in the Cerrado biome in the state of Piauí, Brazil
RESUMO: Algumas espécies de Lonchaeidae (Diptera) são consideradas pragas frugívoras e polífagas, com ampla distribuição geográfica em regiões neotropicais. A relação mosca/planta hospedeira é de grande valor para estudos de comportamento e distribuição de moscas frugívoras. O objetivo deste trabalho foi identificar as espécies de Lonchaeidae

4. First detection of the cosmopolitan invader Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) in Argentina
Abstract: Leptoglossus occidentalis Heidemann is a conifer seed bug, native to North America. This species is considered invasive and has reached several countries in the Northern Hemisphere and most recently Chile in South America. This work reports the first detection of this species in Argentina, with specimens from the Rio Negro province, in 2017. Ecolog

5. Microbial interactions: ecology in a molecular perspective
ABSTRACT The microorganism-microorganism or microorganism-host interactions are the key strategy to colonize and establish in a variety of different environments. These interactions involve all ecological aspects, including physiochemical changes, metabolite exchange, metabolite conversion, signaling, chemotaxis and genetic exchange resulting in genotype sel

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. Seed longevity of Eragrostis plana Nees buried in natural grassland soil
The objective of this research was to evaluate the seed longevity of Eragrostis plana Nees buried at different soil depths, in a natural-grassland area in the Pampa biome (46 m altitude, 30º05´S and 51º40´W) of Rio Grande do Sul State, Brazil. The experimental design was a split-plot type in complete blocks with two factors: seeds buried at five differen

8. 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

9. Clonagem e expressão do gene da tiorredoxina 1 de Paracoccidioides brasiliensis em Pichia pastoris / Cloning and expression of the thioredoxin 1 gene of Paracoccidioides brasiliensis in pichia pastoris
The termodimorphic fungus Paracoccidioides brasiliensis is the etiological agent of paracoccidioidomycosis, a human systemic mycosis of high prevalence in Latin America. P. brasiliensis is exposed to oxidative stress (OS) caused by reactive oxygen species (ROS) produced by the defense cells of the human host. When the invasion by pathogens occurs, the host d

10. DistribuiÃÃo da malacofauna em pilares dos terminais portuÃrios de Cearà - Brasil, com Ãnfase no bivalve invasor Isognomon Bicolor / Distribution of mollusc pillars of the port terminals of Cearà - Brazil, with emphasis on bivalve invader Isognomon Bicolor
Terminais portuÃrios adicionam estruturas artificiais ao ambiente marinho propiciando o estabelecimento de organismos epibÃnticos nativos e espÃcies exÃticas devido à intensa circulaÃÃo de navios. O presente estudo caracterizou e comparou a composiÃÃo especÃfica e a distribuiÃÃo batimÃtrica da malacofauna associada aos pilares dos terminais port

11. Análise citogenética de espécies de Astyanax (Characiformes) da região de transposição do rio Piumhi
The transposition of the Piumhi River caused the introduction of many aquatic species in the São Francisco basin. Species previously restricted to the Upper Paraná basin, such as Leporinus octofasciatus and Parodon nasus, are now present in the São Francisco basin. However, the morphological identification of the invaders is not always possible. This beco

12. Morphology of the alimentary canal of the gecko Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae) / Morfologia do tubo digestivo da lagartixa Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae).
Hemidactylus mabouia is the gecko species more thoroughly distributed in Brazil, being common in anthropic atmospheres, what turns easy its use as model for study of the reptiles. Likewise, aiming at to describe morphologically the alimentary canal of H. mabouia, 17 adult specimens were used, being collected fragments of the esophagus, of the oesophagogastri
