  abstract = {{T}he 2015-2016 {E}l {N}iño event led to one of the most intense and hottest droughts for many tropical forests, profoundly impacting forest productivity. {H}owever, we know little about how this event affected the {C}errado, the largest savanna in {S}outh {A}merica. {H}ere we report 5 years of productivity of the dominant vegetation types in {C}errado, savanna (cerrado) and transitional forest-savanna (cerradão), continuously tracked before, during, and after the {E}l {N}iño. {W}e carried out intensive monitoring between 2014 and 2019 of the productivity of key vegetation components (stems, leaves, roots). {B}efore the {E}l {N}iño total productivity was ~25 % higher in the cerradão compared to the cerrado. {H}owever, cerradão productivity declined strongly by 29 % during the {E}l {N}iño event. {T}he most impacted component was stem productivity, reducing by 58 %. {B}y contrast, cerrado productivity varied little over the years, and while the most affected component was fine roots, declining by 38 % during the event, fine root productivity recovered soon after the {E}l {N}iño. {T}he two vegetation types also showed contrasting patterns in the allocation of productivity to canopy, wood, and fine-root production. {O}ur findings demonstrate that cerradão can show low resistance and resilience to climatic disturbances due to the slow recovery of productivity. {T}his suggests that the transitional {A}mazon-{C}errado ecosystems between {S}outh {A}merica's largest biomes may be particularly vulnerable to drought enhanced by climate change.},
