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...

Drought response strategies of deciduous and evergreen woody species in a seaso...
Souza, Bruno Cruz de; Carvalho, Ellen Cristina Dantas; Oliveira, Rafael S.; Araujo, Francisca Soares de; Lima, André Luiz Alves deDeciduous and evergreen trees are usually considered the main coexisting functional groups in seasonally dry tropical forests (SDTF). We compared leaf and stem traits of 22 woody species in the Brazilian Caatinga to investigate whether deciduous (DC) and evergreen (EV) species have divergent water-use strategies. Our hypothesis was that DC trees compensate for their short leaf longevity by being less conservati...
Why is liana abundance low in semiarid climates?
Carvalho, Ellen Cristina Dantas; Martins, Fernando Roberto; Oliveira, Rafael Silva; Soares, Arlete Aparecida; Araújo, Francisca SoaresLianas are abundant in seasonal tropical forests, where they avoid seasonal water stress presumably by accessing deep-soil water reserves. Although lianas are favoured in seasonal environments, their occurrence and abundance are low in semiarid environments. We hypothesized that lianas do not tolerate the great water shortage in the soil and air characteristic of semiarid environments, which would increase the ...
Hydraulic architecture of lianas in a semiarid climate: efficiency or safety?
Carvalho, Ellen Cristina Dantas; Martins, Fernando Roberto; Soares, Arlete Aparecida; Oliveira, Rafael Silva; Muniz, Celli RodriguesXylem anatomical traits can provide insights regarding the mechanisms affecting the distribution of vascular plants across environmental gradients. In this study, we aimed to investigate the hypothesis that lianas occurring in semiarid environments have characteristics that maximize the xylem resistance to tension-induced cavitation along the root- -stem-branch continuum. To gather information regarding the hyd...
