We studied wood anatomy and specific gravity in a total of 18 trees of Ocotea curucutuensis, a recently described species, lacking wood anatomical information. Nine sample trees were obtained in each of two areas, Pico do Itapeva (PI) and Núcleo Curucutu (NC), both in the state of São Paulo, Brazil. These areas have marked differences in precipitation, altitude, and temperature. Anatomical differences between the two populations appeared related to tree size, and possibly indirectly to climate. Higher wood specific gravity related with the smaller diameter in NC trees is hypothesized to contribute to mechanical support of the epiphyte-laden trees and to resistance against the prevailing strong winds.

ABSTRACT Hydrological processes in forest stands are mainly influenced by tree species composition and morpho-physiological characteristics. Few studies on anatomical patterns that govern plant hydraulics were conducted in tropical forest ecosystems. Thus, we used dye immersion to analyze sapwood area patterns of 34 trees belonging to 26 species from a terra firme forest in the central Brazilian Amazon. The sapwood area was related with wood anatomy and tree size parameters (diameter-at-breast-height - DBH, total height and estimated whole-tree volume). Exponential allometric equations were used to model sapwood area using the biometrical variables measured. Sapwood area traits (cross-section non-uniformity and heartwood visibility) varied significantly among and within species even though all were classified as diffuse porous. DBH was strongly and non-linearly correlated with sapwood area (R 2 = 0.46, P < 0.001), while no correlation was observed with vessel-lumen diameter (P = 0.94) and frequency (P = 0.58). Sapwood area and shape were also affected by the occurrence of vessel obstruction (i.e., tyloses), hollow stems and diseases. Our results suggest that sapwood area patterns and correlated variables are driven by intrinsic species characteristics, microclimate and ecological succession within the stand. We believe that individual tree sapwood characteristics have strong implications over water use, hydrological stand upsaling and biomass quantification. These characteristics should be taken into account (e.g., through a multi-point sampling approach) when estimating forest stand transpiration in a highly biodiverse ecosystem.

Data on fossil dicotyledonous wood were assembled in order to 1) test the Baileyan model for trends of specialisation in dicotyledonous wood anatomy by addressing the question - were 'primitive' wood anatomieal features (as defined by the Baileyan model) more common in the geologie past than at present?, 2) infer, on a broad geographie scale, past climatie regimes, and long term climatic change, and 3) assess the extent of knowledge of fossil dicotyledonous woods. The resulting database has information on 91 anatomieal features for over 1200 fossil dicotyledonous woods. The incidence of selected anatomical features was plotted through time (by geologie epoch) for the world and for two regional groupings (roughly corresponding to the Laurasian and Gondwanan supercontinents). For comparison to the fossil wood record, the incidence of wood anatomie al features in the Recent flora was obtained from the 5260 record OPCN database for extant dicotyledonous woods.

A comparison is made between ecological trends in wood anatomy found in southern California and Israel and adjacent regions. Trends for type of vessel perforation, vessel member length and the occurrence of helical thickenings show striking parallels. Characters like vessel diameter and frequency and incidence of (fibre-)tracheids show only weakly similar trends. Vessel grouping and ring-porosity do not show any parallel in the data for southern California and Israel. The differences between the two floras can largely be attributed to different floristic composition and the alternative possibilities for safe and efficient xylem sap transport and drought resistance in different taxa.
