Abstract:	The Brazilian Savanna (Cerrado) is the second-largest Brazilian biome with an area of approximately 2 million km2. Because of its high diversity of plants and vertebrates, many of them endemics, this biome is considered a global biodiversity hotspot. However, due to agricultural expansion and urban development, up to 45% of its original area has been deforested, and 34% of the remaining native areas is likely to be cleared by 2050. Among the most frequent disturbance sources in this biome, fire and invasive species stand out. Fire is a fundamental component of the Cerrado biome. However, human actions are changing its behavior. As a consequence, fire regime changes can foster vegetation transitions such as biological invasions. In its turn, invasive plants suppress natives, impacting many ecosystem compartments. Also, they can alter the frequency and severity of fires, which may further promote the dominance of invaders on native ecosystems. These subjects have been studied in the context of Cerrado and the majority of researches addresses its effects on the diversity of native plants. On the other hand, its ecohydrological impacts on ecosystems remain largely unknown. Therefore, this dissertation tries to fill part of this gap presenting two separated chapters. The first presents a systematic review regarding the fire effects on soil water infiltration and the second addresses the effects of invasive plants (Pteridium arachnoideum) on soil water infiltration of riparian zones within the Cerrado biome.
