|Title:||O uso de calorimetria em ecologia|
|Title Alternative:||The use of calorimetry in ecology|
|Abstract:||The macroscopic effects caused by sun radiation and the mankind-nature interactions in a ecosystem are firstly presented. However, the importance of calorimetric determinations to clarify some phenomena related to the living microorganism populations and their interactions with the food additive or inhibitor agents are reported. The collect values illustrate the occurence a great deal of effects in this microscopic world. For this subject, the reachest Latosol soil was selected due to the content of organic matter and consequently in microorganisms. Microbial activity was stimulated by addition of glucose, which showed to be the best nutrient source. Inhibitory effect was detected with many compounds used in the agriculture like some herbicides and fungicides. Although the assays are based on the use of the microcalorimetry, other techniques like respirometry contributes strongly to the understanding of the ecosystem. The main objective in this exposition is to stimulate by means of many interesting examples, the importance of preserving the environment in order to establish direct analogies by using the Chemistry in the daily life.|
