The negative effect of lianas on tree growth varies with tree species and season

Lianas reduce tree growth, reproduction, and survival in tropical forests. Liana competition can be particularly intense in isolated forest fragments, where liana densities are high, and thus, host tree infestation is common. Furthermore, lianas appear to grow particularly well during seasonal droug...

description Lianas reduce tree growth, reproduction, and survival in tropical forests. Liana competition can be particularly intense in isolated forest fragments, where liana densities are high, and thus, host tree infestation is common. Furthermore, lianas appear to grow particularly well during seasonal drought, when they may compete particularly intensely with trees. Few studies, however, have experimentally quantified the seasonal effects of liana competition on multiple tree species in tropical forests. We used a liana removal experiment in a forest fragment in southeastern Brazil to test whether the effects of lianas on tree growth vary with season and tree species identity. We conducted monthly diameter measurements using dendrometer bands on 88 individuals of five tree species for 24 months. We found that lianas had a stronger negative effect on some tree species during the wet season compared to the dry season. Furthermore, lianas significantly reduced the diameter growth of two tree species but had no effect on the other three tree species. The strong negative effect of lianas on some trees, particularly during the wet season, indicates that the effect of lianas on trees varies both seasonally and with tree species identity. in Portuguese is available with online material. RESUMO Lianas reduzem o crescimento, reprodução e a sobrevivência de árvores em florestas tropicais. A competição entre lianas e árvores pode ser particularmente intensa em fragmentos florestais isolados, onde lianas apresentam altas densidades e, portanto, é comum a infestação de indivíduos arbóreos. Além disso, lianas mantêm seu crescimento durante secas sazonais, quando competem intensamente com as árvores. No entanto, poucos estudos quantificaram experimentalmente os efeitos sazonais da competição de lianas em diferentes espécies arbóreas em fragmentos de florestas tropicais. Aqui utilizamos um experimento de remoção de lianas em um fragmento de floresta semidecidual no sudeste do Brasil para testar se os efeitos de lianas no crescimento das árvores variam com a estação e identidade das espécies arbóreas. Realizamos medições diamétricas usando bandas dendrométricas em 88 indivíduos de cinco espécies diferentes de árvores por 24 meses. Lianas tiveram um efeito negativo mais intenso em algumas espécies de árvores durante a estação chuvosa em comparação com a estação seca. Além disso, lianas reduziram significativamente o crescimento diâmétrico de duas espécies de árvores, mas não tiveram
