Gregarious insects, like cockroaches, aggregate in shelters during their resting period. How do individuals reach a collegial decision? What is the relation between the distributions of the individuals and the parameter values characterizing the population and the environment? With a model based on experimental data, we demonstrated that the collegial decision is based on the relation between t...

Understanding the distribution of landscape variables presents several advantages to researchers focusing on ecological studies. The Normalized Difference Vegetation Index (NDVI) is a relatively common productivity variable used to assess, monitor, and compare landscapes. In this study, an NDVI layer was created using Satellite Pour l'Observation de la Terre 4 (SPOT 4) satellite imagery to comp...

An examination of peridomestic area organization and triatomine collection in an endemic village for Chagas disease (Jalisco State) identified the habitat of Triatoma longipennis (dominant species) and the risk factors of peridomestic infestation. In 100 visited peridomestic areas, 369 structures (permanent, temporary, and natural) were submitted to active manual research of triatomines. Storag...

The purpose of this study was to analyze, within a more extensive intervention program, the existence of positive emotions and positive coping in the refugees at the two largest shelters created after the earthquakes of El Salvador in January, 2001. One hundred and fifteen survivors were interviewed in the shelters about different aspects related to positive cognitions and emotions experienced ...

In disaster management, evacuation modeling is considered a useful visual tool to managers for reviewing current strategies, estimating the ability of shelters accommodate all evacuees, and developing route planning. Though there are several existing studies on in case an earthquake, research that integrates road blockades into simulations quite limited. From viewpoint, this aims develop with c...

Soybean grain yield has regularly been impaired by drought periods, and the future climatic scenarios for soybean production might drastically impact yields worldwide. In this context, knowledge of is extremely important to subsidize government corporative decisions over technical issues. This paper aimed predict in crop grown under different levels water availability using reflectance spectros...
