Arthropod Diversity in a Tropical Forest
This work sampled the phylogenetic breadth of arthropod taxa from the soil to the forest canopy in the San Lorenzo forest, Panama using a comprehensive range of structured protocols and found that models based on plant diversity fitted the accumulated species richness of both herbivore and nonherbivore taxa exceptionally well.
Ponericins, New Antibacterial and Insecticidal Peptides from the Venom of the Ant Pachycondyla goeldii *
In the venom of the predatory ant Pachycondyla goeldii, the estimated peptide concentrations appear to be compatible with an antibacterial activity in vivo, suggesting that in the ant colony, the peptides exhibit a defensive role against microbial pathogens arising from prey introduction and/or ingestion.
Rainforest Canopy Ants: The Implications of Territoriality and Predatory Behavior
The methods that permit us to study “arboreal ant mosaics” are discussed, which are good predators that use group ambushing to catch flying insects on their host tree foliage and are frequently used as biological control agents.
Parasitism versus mutualism in the ant-garden parabiosis between Camponotus femoratus and Crematogaster levior
The results show that both species take part in protecting the epiphytes, refuting the role of Cr.
A new case of trophobiosis between ants and Heteroptera.
Understorey environments influence functional diversity in tank‐bromeliad ecosystems
The results provide evidence that tank-bromeliads, which grow in a broad range of ecological conditions, promote aquatic food web diversity in neotropical forests and show that algal production can support a non-detrital food web in these systems.
A new method based on taxonomic sufficiency to simplify studies on Neotropical ant assemblages
Diversity and nest site selection of social wasps along Guianese forest edges: assessing the influence of arboreal ants.

The predatory behavior of Platythyrea conradti, an arboreal ponerine ant, whereas most species in this subfamily are ground-dwelling is studied, where the workers are able to capture a wide range of prey, including termites and agile, nocturnal insects as well as diurnal insects that are inactive at that moment of the Nyctemeron.

The pollination of Philodendron solimoesense was studied in four populations of French Guiana and showed that C. colasi is not likely to depend on chemical information to localize conspecifics but may rely instead on stimuli produced by the inflorescences in order to meet mating partners.
