Assembly rules in a resource gradient: competition and abiotic filtering determ...
Menezes, Bruno Sousa; Martins, Fernando Roberto; Carvalho, Ellen Cristina Dantas; Souza, Bruno Cruz; Silveira, Andrea PereiraThe relative importance of different community assembly mechanisms varies depending onthe environment. According to the stress-dominance hypothesis (SDH), assembly mecha-nisms range from strong abiotic filtering to competition as the environment becomes morefavourable. Most evidence for the SDH comes from studies in gradients of conditions (i.e.abiotic environmental factors that influence the functioning of org...
Is the spatial pattern of a tree population in a seasonally dry tropical climat...
Silveira, Andreia Pereira; Martins, Fernando Roberto; Menezes, Bruno Sousa; Araújo, Francisco SoaresSpatial pattern of tropical plants is initially generated by limited seed dispersal, but the role of density-dependent and independent mechanisms as modifiers of these patterns across ontogeny is poorly understood. We investigated whether density-dependent mortality (DDM) and environmental heterogeneity can drive spatial pattern across the ontogeny of a tree in a seasonally dry tropical climate. We used Moran’s...
