Ants as Indicators in Brazil: A Review with Suggestions to Improve the Use of Ants in Environmental Monitoring Programs

Psyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
We describe the use of ants as indicators in Brazil, based on a critical review of published articles. The analysis of fifty‐eight papers, encompassing a range of almost 25 years, indicates an increased number of studies using ants as indicators in the last decade. Among the parameters analyzed in the papers, species composition is the most suitable to

Glycosaminoglycans Modify Elastase Action In Vitro and Enhance Elastase‐Induced Cell Death in Cultured Fibroblasts

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Human neutrophil elastase (HNE) has been shown to be involved on death of different cell types, including epithelial lung cells, which is related to several pulmonary diseases. Since HNE activity may be influenced by extracellular matrix (ECM) molecules such as glycosaminoglycans (GAGs), and fibroblasts are the most common ECM‐producing cells of lung ...

Environmental Factors Influencing Foraging Activity in the Social Wasp Polybia paulista (Hymenoptera: Vespidae: Epiponini)

Psyche: A Journal of Entomology, Volume 2011, Issue 1, 2011., 2011
Foraging behavior in social wasps is important in the development of the colony and reflects an important ecological interaction between the colony and the environment. Although the social traits of the colony play a role in the foraging activities, the conditions that establish the space and time limits are mainly physical.
