Studies on the influence of leaf temperature rise on gas exchange in tropical tree species grown in plantations are rare. With regard to the predicted increase in air temperature in the future in the Central Amazon, we investigated the influence of increasing leave temperature on the gas exchange of oil palms cultivated in monocultures as well as in mixed plantations with cassava or banana. This study was carried out at the Embrapa Experimental Station in Presidente Figueiredo - AM - Brazil, 60 km north of Manaus. The net photosynthesis (Pn), transpiration (E), stomatal conductance (gs) and the water use efficiency (WUE) of the plants were quantified by a portable photosynthesis meter (CI-340). In all plantations increasing leaf temperatures caused a significant decrease of the net photosynthesis (Pn), stomatal conductance (gs), and the water use efficiency (WUE) of the oil palms. Maximum transpiration rates (E) were observed at leaf temperatures between 38 and 46°C. In addition to the influence of leaf temperature rise, the planting system also had a significant influence on the gas exchange of palm plants. |

Crop-livestock systems are regaining their importance as an alternative to unsustainable intensive farming systems. Loss of biodiversity, nutrient pollution and habitat fragmentation are a few of many concerns recently reported with modern agriculture. Integrating crops and pastures in no-till systems can result in better environmental services, since conservation agriculture is improved by system diversity, paths of nutrient flux, and other processes common in nature. The presence of large herbivores can positively modify nutrient pathways and soil aggregation, increasing soil quality. Despite the low diversity involved, the integration of crops and pastures enhances nature?s biomimicry and allows attainment of a higher system organization level. This paper illustrates these benefits focusing on the use of grazing animals integrated with crops under no-tillage systems characteristic of southern Brazil. |
