Invasive non-native species in Brazil an updated overview

We provide an updated list of invasive animals, plants and algae in Brazil that is fully integrated and based on the same criteria and lexicon to define invasive species across all plant and animal taxa and habitats for Brazil.

Is the use of drones cost-effective and efficient in detecting invasive alien trees? A case study from a subtropical coastal ecosystem

We present in this paper the assessment of the effectiveness of using drones to detect invasive pines in a protected area in a coastal ecosystem of southern Brazil.

Species diversity, community structure and ecological traits of trees in an upper montane forest, Southern Brazil

Tree species diversity and community structure, ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest remnant.

Citizen engagement in the management of non-native invasive pines: Does it make a difference?

We present in this paper the assessment of the effectiveness of a volunteer program for the control of invasive pines in a protected area (PA) in a coastal zone of southern Brazil.

Interaction of land management and araucaria trees in the maintenance of landscape diversity in the highlands of southern Brazil

Abundance and species composition of trees are affected by land management and araucaria crown influence.

Facilitation influences patterns of perennial species abundance and richness in a subtropical dune system

Nurse plants play a key role in *restinga* environments and their presence is critical to maintain ecosystem diversity and function.

Spatial distribution, association patterns and richness of tree species in a seasonal forest from the Serra Geral formation, southern Brazil

Most species showed an aggregated distribution. Both association and dissociation patterns occurred among species leading to distinct forest patches.'

Entomofauna associated to the floration of Schinus terebinthifolius Raddi (Anacardiaceae) in the Rio Grande do Sul state, Brazil

We collected 1.624 insects belonging to eight orders and 64 families on the flowers of one individual of S. terebinthifolius. Diptera showed higher family richness with 17, followed by Hymenoptera with 12 and Hemiptera with 11. Vespidae and Apidae, with 616 and 317 individuals respectively, were the families with the greatest number of individuals collected. 92.0% of these insects had pollen attached to their body, which confirms the importance of these insects as pollen vector and potential pollinators.

Floristic-geographic relationships in a forest structure at the central region of the State of Rio Grande do Sul, Brazil.

Most of the species surveyed are widely distributed across southern Brazilian vegetation formations. A large proportion of species belonged to the western seasonal contingent.

Pollen vector wasps (Hymenoptera, Vespidae) of Schinus terebinthifolius Raddi (Anacardiaceae), Santa Cruz do Sul, RS, Brazil

The wasps Polistes versicolor, P. simillimus, Polybia sericea and P. ignobilis had large quantities of pollen on their body, beyond high values of dominance and constancy, proving its importance on pollen transportation and potential to act as pollinators of Schinus terebinthifolius.
