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...
Atributos de historia de vida, estrutura e dinâmica populacional de árvore sob ...
Silveira, Andrea PereiraThe rainfall seasonality and stochasticity are the main regulators of structure and population dynamics in seasonally dry tropical vegetations. This stochasticity, however, can result in heterogeneous environments both in relation to water availability as in the availability of vertical and horizontal light. In deciduous thorny woodland vegetation of semiarid northeastern Brazil (caatinga), one of the most abun...
