"EFFECTS OF SHADOWING AND EUTROFIZATION ON THE DEVELOPMENT OF AN INVASIVE MACROPHY: Urochloa arrecta."
Aquatic macrophytes, Eutrophication, Shading, Light, Urochloa arrecta.
Aquatic macrophytes are very easy to develop due to their ability to disperse, due to the ability to reproduce vegetatively, reaching distant places and environments that provide favorable conditions. Eutrophication and the influence of light also aid in its development. The study species, Urochloa arrecta, from the Poaceae family is widely distributed and is resistant to environmental changes. This project aims to speculate whether shading and eutrophication can change the development of this species. Seeking to evaluate the effects of different levels for both shading and eutrophication in the structure of the grass Urochloa arrecta. The site to be collected will be in the Parque do Utinga Camillo Viana in Belém and the experiment will take place in the greenhouse of the Federal University of Pará - UFPA in the same municipality. The budget provides for the purchase of materials that will assist in the simulation of shading and concentration of nutrients. With these results you will be able to know if places prone in these conditions will have more or less development and establishment of the invasive species.
