Continuous landscape components along the lateral riverside are affected by both hydrologic connectivity and disconnectivity. In recent years, anthropogenic activities climate changes have caused wetland shrinkage land degradation of many arid semiarid regions. Since microorganisms major drivers soil biochemical cycling, it is essential to examine microbial communities continuum understand thei...

The influence of water brownification (an increase in color) on floating-leaved macrophytes appears to be an important issue predicting the consequences climate change freshwater ecosystems. To fill gap knowledge this area, we performed a laboratory experiment aiming test impact humic acid (HA) Lemna minor sampled from oxbow lake. Plants were exposed over seven days four different additions pur...

We present a representational format for observed movements The representation has a temporal structure relating components of a single complex movement. We also present OXBOW, an unsupervised learning system, which constructs classes of these movements. Empirical results indicate that the system builds abstract movement concepts with appropriate component structure allowing it to predict the l...

Assays were carried out to evaluate effects of detritus size on the mineralization of an aquatic macrophyte, the Oxycaryum cubense. Samples of plant and water were collected from an oxbow lake, the Infernão lagoon (21 degrees 35' S and 47 degrees 51' W) located at Mogi Guaçu river floodplain. The plants were taken to the laboratory, washed under tap water, dried (50 degrees C) and fractioned in...
