A Periodicity Theorem for Trees
In this paper we extend the notion of periodicity from words to labelled ordered trees. This is achieved by deening an equivalence relation on the support of the tree (the set of the nodes) and by requiring that equivalent nodes have the same label. Another requirement is that corresponding sons of equivalent nodes are equivalent too. Since the support of a k-ary tree may be described by a pree...
متن کاملDecelerating growth in tropical forest trees.
The impacts of global change on tropical forests remain poorly understood. We examined changes in tree growth rates over the past two decades for all species occurring in large (50-ha) forest dynamics plots in Panama and Malaysia. Stem growth rates declined significantly at both forests regardless of initial size or organizational level (species, community or stand). Decreasing growth rates wer...
متن کاملLow mortality in tall tropical trees
The dynamics of the tallest trees in tropical forests are of special interest due to their carbon content, canopy dominance, and the large canopy gaps created when they die. Known ecological mechanisms that may influence tall tree survival lead to conflicting predictions. Hydraulic stress and exposure to high winds and desiccation should increase death rates, yet the tallest trees have the grea...
متن کاملPhenology of temperate trees in tropical climates.
Several North American broad-leaved tree species range from the northern United States at approximately 47 degrees N to moist tropical montane forests in Mexico and Central America at 15-20 degrees N. Along this gradient the average minimum temperatures of the coldest month (T (Jan)), which characterize annual variation in temperature, increase from -10 to 12 degrees C and tree phenology change...
متن کاملBeta-diversity in tropical forest trees.
The high alpha-diversity of tropical forests has been amply documented, but beta-diversity-how species composition changes with distance-has seldom been studied. We present quantitative estimates of beta-diversity for tropical trees by comparing species composition of plots in lowland terra firme forest in Panama, Ecuador, and Peru. We compare observations with predictions derived from a neutra...
