Levels of leaf Herbivory in Amazonian trees from different stages In forest regeneration

Abstract: -Leaves from 120 canopy trees and 60 understory tree saplings growing in levels of herbivory (percent leaf area lost). Overall, levels of herbivory on leaves of central Amazonian trees were low. About one quarter of the leaves examined (n = 855) had no damage at all. In most other Neotropical sites studied the mean percentage of herbivory was found to vary between 5.7 and 13.1%, whereas in Manaus it was only 3.1%. The data presented here Also, there was no difference in damage between leaves from pioneer and l… Show more

“…Thus, although shade tolerance and successional status of a plant species frequently correlate with its inherent growth rate, these characteristics of plant ecological strategies appeared weaker predictors of foliar losses to insects when compared to growth rates. We conclude that the earlier reports of differences in foliar losses between shade‐tolerant and shade‐intolerant plants, as well as between early and late successional species (Coley & Barone ; Vasconcelos ; Poorter et al . ; Villagra et al .…”

“…A higher average population size of herbivorous insects and, consequently, higher foliar losses to these insects were predicted for early successional (pioneer) species than for late successional (climax) species (Lawton & McNeill ; Godfray ). However, exploration of diverse communities of woody plants revealed no relationships between plant successional status and herbivory (Vasconcelos ; Poorter et al . ).…”

“…The positive correlation between herbivory and precipitation discovered in our study is difficult to explain, because earlier studies reported either the absence of a precipitation effect on leaf damage by insects (Vasconcelos, ) or higher herbivory in dry forests relative to wet forests (Mazía et al ., ). The effects of precipitation have been largely neglected in current research on climate change in general (Bale et al ., ) and on the effects of climate on herbivory in particular.…”

“…Em uma floresta chuvosa, a abundância de artrópodes foi maior no estrato superior (dossel), entretanto o dano foliar foi maior no estrato inferior (sub-bosque) (BASSET et al, 1992). Na floresta amazônica, onde o solo é pobre em nutrientes, não houve diferença signifcativa no nível de herbivoria entre árvores do dossel e arvoretas do sub-bosque e também entre plantas de mata secundária e de mata primária (VASCONCELOS, 1999). Apesar do solo de cerrado também ser pobre em nutrientes, a diferença encontrada na perda de área foliar entre os arbustos e as árvores no presente estudo provavelmente seja devida ao ambiente dinâmico do cerrado que disponibiliza novos órgãos e/ou novos indivíduos com maior frequência do que em outros biomas.…”
