A novel index of leaf RGR predicts tree shade tolerance

Tolerance of soil pathogens co-varies with shade tolerance across species of tropical tree seedlings.
A negative feedback between local abundance and natural enemies could contribute to maintaining tree species diversity by constraining population growth of common species. Soil pathogens could be an important mechanism of such noncompetitive distance and density-dependent (NCDD) mortality, but susceptibility to local pathogens may be ameliorated by a life history strategy that favors survivorsh...
متن کاملTolerance to herbivory and the resource availability hypothesis.
The resource availability hypothesis (RAH), the most successful theory explaining plant defence patterns, predicts that defence investment is related to the relative growth rate (RGR) of plant species, which is associated with habitat quality. Thus, fast-growing species should show lower resistance than slow-growing species, which would lead fast growers to sustain higher herbivory rates, but t...
متن کاملA novel algorithm to determine the leaf (leaves) of a binary tree from its preorder and postorder traversals
Binary trees are essential structures in Computer Science. The leaf (leaves) of a binary tree is one of the most significant aspects of it. In this study, we prove that the order of a leaf (leaves) of a binary tree is the same in the main tree traversals; preorder, inorder, and postorder. Then, we prove that given the preorder and postorder traversals of a binary tree, the leaf (leaves) of a bi...
متن کاملA shade tolerance index for common understory species of northeastern North America
Since Baker’s [Baker, F.S., 1949. A revised tolerance table. J. For. 47, 179–181] classic contribution, shade tolerance indices have not been much modified for North American plant species. While many common tree and shrub species are included in the shade tolerance index, much less is known about this characteristic for the abundant and rich understory vascular and nonvascular plant layers. Th...
متن کاملSeedling growth of fifteen Brazilian tropical tree species differing in successional status
(Seedling growth of fifteen Brazilian tropical tree species differing in successional status). Growth of seedlings of fifteen tropical tree species representative, at the adult stage, of different successional positions, was studied under field conditions. Seedlings were grown in three treatments: full sun (FS), artificial shade imposed by neutral screens (AS) and natural shade imposed by a clo...
