Covering regular graphs with forests of small trees
A (d, k) -forest is a forest consisting of trees whose diameters are at most d and whose maximum vertex degree ,6. is at most k. The (d, k)-arboricity of a graph G is the minimum number of (d, k}-forests needed to cover E(G). This concept is a common generalization of linear k-arboricity and star arboricity. Using a probabilistic approach developed recently for linear karboricity, we obtain an ...
متن کاملFungi at a Small Scale: Spatial Zonation of Fungal Assemblages around Single Trees
Biological communities are often structured by environmental factors even at small spatial scales. Fungi are no exception, though the patterns and mechanisms underlying their community structure are usually unknown. Previous work documented zonation in fungi under tree canopies primarily through their fruiting patterns. Here we investigate the existence of zonation patterns in fungal communitie...
متن کاملSeed Dispersal and Spatial Pattern in Tropical Trees
Theories of tropical tree diversity emphasize dispersal limitation as a potential mechanism for separating species in space and reducing competitive exclusion. We compared the dispersal morphologies, fruit sizes, and spatial distributions of 561 tree species within a fully mapped, 50-hectare plot of primary tropical forest in peninsular Malaysia. We demonstrate here that the extent and scale of...
متن کاملFunctional Diversity of Small and Large Trees along Secondary Succession in a Tropical Dry Forest
Functional Diversity is considered an important driver of community assembly in environmental and successional gradients. To understand tree assembly processes in a semideciduous tropical forest, we analyzed the variation of Functional Richness (FRic), Functional Divergence (FDiv), and Functional Evenness (FEve) of small vs. large trees in relation to fallow age after slash-and-burn agriculture...
متن کاملSpecies of Colletotrichum associated with citrus trees in Iran
Colletotrichum species are associated with citrus plants as pathogens, saprobes and endophytes. According to the most recent multigene phylogenetic analysis, a lot of changes were happened in the taxonomy and species delimitation in the genus Colletotrichum. In this investigation, 292 Colletotrichum isolates were obtained from leaves, fruits and stems of Citrus species at Golestan, Mazandaran, ...
