MICROBIAL DIVERSITY OF A BRAZILIAN COASTAL REGION INFLUENCED BY AN UPWELLING SYSTEM AND ANTHROPOGENIC ACTIVITY.

Microbial diversity of a Brazilian coastal region influenced by an upwelling system and anthropogenic activity.

BackgroundUpwelling systems are characterised by an intense primary biomass production in the surface (warmest) water after the outcrop of the Sharpening bottom (coldest) water, which is rich in nutrients.Although it is known that the microbial assemblage plays an important role in the food chain of marine systems and that the upwelling systems tha

Diversifying cereal-based rotations to improve weed control. Evaluation with the AlomySys model quantifying the effect of cropping systems on a grass weed

Simplified rotations often select weed flora consisting of one or several dominant species.In rotations consisting mainly of winter cereals, one of the most frequent weeds in Atlantic European countries is blackgrass (Alopecurus myosuroides Huds.).In order to reduce environmental impacts and avoid the selection Adhesive Tape of herbicide-resistant
