  abstract = {{T}he {C}errado-{A}mazonia transition harbors forest and savanna formations under the influence of pronounced climate seasonality; however,


the water use strategies of this key region is not yet well understood. {T}his study aimed at deciphering in intra- and interspecific


variability in leaf water potential regulation among species across three distinct vegetation types (typical cerrado, cerradão, and


semideciduous seasonal forest) of the {C}errado-{A}mazonia transition region. {W}e expected a variation across iso/anisohydric strategies


driven by plant-environment interactions and by species attributes (phenology and wood density). {W}e selected 21 dominant species


(seven per vegetation type), recorded their phenological strategy and wood density, and measured leaf water potential ({P}sil) during


the dry and rainy seasons to analyze variations associated with minimum {P}sil, predawn {P}sil ({D}ela {P}si pd), and midday {P}si l ({D}ela {P}si md) under the effect


of variable vapor pressure deficit ({VPD}). {T}he variation in {P}si l across species was higher in the dry season than in the rainy season for


all vegetation types. {M}ost species from typical cerrado and cerradão showed similar behavior patterns, with higher {P}sil regulation under


high {VPD} and lower {D}ela {P}si pd. {I}n contrast, most forest species showed lower regulation under high {VPD}, and higher {D}elta {P}si pd. {T}otal or partial


deciduousness together with strong stomatal regulation seems to be common water regulation strategies in the dry season for cerrado


species but not for forest species. {O}ur results suggest that, if drought events become more intense and frequent as predicted, seasonal


forest species may be more vulnerable due to their lower {P}si l regulation.},
