Several wood anatomical features within the subfamily, viz. tangential vessel diameter, average length of tracheary elements, height of multiseriate rays, and presence of prismatic crystals are negatively correlated with increasing latitude, while vessel density and helical thickenings show a positive correlation with increasing latitude. Similar latitudinal trends are found within the genus Vaccinium (31 species studied). The correlation between various wood anatomical features and latitude is surprisingly high despite the fact that most tropical species grow in montane regions, which are rather similar to the temperate, non-tropical habitats as regards climatic conditions. Altitudinal trends, however, are weak. The impact of different life forms (shrubs, trees and lianas) and the amount of precipitation also plays a significant role in various continuous wood features. Furthermore, some of these anatomical features are correlated with each other. Part of the variation in vessel characters may be the result of functional adaptations to different climatic zones and environments, especially with respect to conductive efficiency and safety.

This could also suggest that there might be a threshold altitude at 2000 m, as suggested by Noshiro \& Baas (2000), indicating that the influence of altitude above 2 000 m is more or less similar for all woody taxa. The impact of precipitation on the wood structure of Vaccinioideae is similar compared to the habit effect. Species from environments with 500 to 1000 mm annual precipitation show a high percentage of scalariform perforation plates, a narrow vessel diameter and high vessel density, short tracheary elements, and relatively narrow and low multiseriate rays, while species growing in very wet environments (more than 2500 mm annual precipitation) have a higher percentage of simple perforations, wider and fewer vessels, longer tracheary elements, and broader and higher multiseriate rays. but precipitation is strongly correlated with latitude in this study.}, interhash = {139425ee2faf2774be0548e3327e2fcb}, intrahash = {18c735645cde81d3a008533f6a2d1976}, journal = {Flora}, keywords = {bibtex-import, citeulikeExport diameter, environmental, gradients}, pages = {309--319}, posted-at = {2007-07-31 06:37:44}, priority = {2}, timestamp = {2019-03-31T01:16:26.000+0100}, title = {{Ecological trends in the wood anatomy of Vaccinioideae (Ericaceae s.l.)}}, volume = 199, year = 2004 }
