             abstract = "The Amazon basin is one of the major engines of the global water 
                         cycle. It is also comprised of 30 distinct ecoregions with 
                         distinct vegetation types. Correspondingly, the impacts of forest 
                         disturbances and stresses on their hydrologic responses to a 
                         changing climate are expected to vary across the basin. In the 
                         face of an increasingly changing climate, identifying the effects 
                         of extreme droughts in different Amazonia ecoregions leading to 
                         unstable hydrologic behavior is important for understanding the 
                         role different forest types have in the water cycling dynamics of 
                         the entire basin. In this work, we use the hydrologic sensitivity 
                         index to quantify observed changes in the hydrologic responses of 
                         Amazonian forests that have experienced significant deforestation 
                         events to document the most hydrologically sensitive ecoregions 
                         within the basin and report the differences in response to three 
                         of the most recent extreme Amazon drought events (2005, 2010, and 
                         2015). Our results show clusters of hydrologic sensitivity areas 
                         within similar ecoregions with specific vegetation and landscape 
                         characteristics that we use to attempt to identify the underlying 
                         factors leading to such responses. Ultimately, this work aims to 
                         situate the ecoregions of the Amazon basin that are closer to 
                         reaching a critical threshold of forest cover loss that may lead 
                         to irreversible changes in ecosystem services and water cycle 
                         dynamics.",
