Two Populations

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.

The World

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.

Helical Thickenings

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.

Foliar Morphology

Miconia sellowiana (Melastomataceae), a widespread species occurring in Araucaria Forest, Montane Dense Forest and Upper Montane Forest (Paraná state, Brazil) has a highly variable foliar morphology. This study investigated whether the wood anatomy follows this pattern influenced by environmental conditions. Samples of six individuals per area were collected, fixed and prepared, according to standard techniques in wood anatomy. ANOVA indicated differences for length and diameter of vessel elements and fibres, fibre wall thickness, width of rays and ray frequency, especially regarding the population of the Upper Montane Forest. The secondary xylem from this vegetation is characterized by shorter vessel elements and fibres, thicker fibre walls and wider rays. These characteristics are associated to a certain degree of water stress imposed to the plants in the Upper Montane Forest, mainly due to the shallow neosol soils. The Araucaria Forest and the Montane Dense Forest have more similar environmental conditions, supported by the Cluster analysis. The Principal Components Analysis explained 98% of the total variance, where fibre and vessel element lengths showed a posi-tive correlation; however, this analysis did not allow the separation of three distinct groups. Although less pronounced, the wood anatomical differences corroborate the results obtained with foliar morphology, where leaves from the Upper Montane Forest presented the most xeric characteristics among the populations of Miconia sellowiana studied.
