abstract = "Dominant tree species from a south-eastern Brazilian savanna
showing different leaf phenologies (evergreen, semi-deciduous and
deciduous) were characterized regarding photosynthetic potential
(A), leaf nitrogen content (% N), specific leaf area (SLA),
photosynthetic nitrogen (PN) and photosynthetic nitrogen use
efficiency (PNUE). The ecophysiological traits evaluated
seasonally (dry and wet season) characterized a gradient of
strategies among three species: the evergreen species that
dominates lower strata, showed low % N, SLA, Amax and Amass and
high PNUE; the semi-deciduous species that dominates intermediate
strata, showed medium leaf nitrogen and SLA and high Amax, Amass
and PNUE; the deciduous species that dominates the canopy, showed
high leaf N, SLA, Amax and Amass and low PNUE. Non deciduous
species invested relatively more nitrogen in photosynthesis during
the wet season, while the deciduous species maintained higher PN
in the dry season. Photosynthetic N and PNUE appear to be the key
to a better understanding of the relations among leaf traits, N
content and photosynthetic potential in species with different
leaf phenologies and subjected to climatic seasonality.",
