“…We obtained meteorological data for each of the studied sites for the 24 months preceding the study—a period corresponding to vegetative investment by each plant (Fagundes et al, ). The data were obtained from the closest meteorological station to each of the sites using the public platform of the Brazilian Meteorological Institute (http://www.inmet.gov.br).…”

Environmental factors act as drivers of species coexistence or competition. Mesic environments favor the action of parasites and predators on gall communities, while the factors that determine the structure of gall communities in xeric environments remain unknown. We evaluated the structure of gall communities along an environmental gradient defined by intrinsic plant characteristics, soil fertility, and aridity, and investigated the role of competition as a structuring force of gall communities in xeric environments. We created null models to compare observed and simulated patterns of co‐occurrence of galls and used the C‐score index to assess community aggregation or segregation. We used the NES C‐score (standardized C‐score) to compare patterns of co‐occurrence with parameters of environmental quality. Xeric environments had poorer and more arid soils and more sclerophyllous plants than mesic environments, which was reflected in the distribution patterns of gall communities. Values of the C‐score index revealed a segregated distribution of gall morphospecies in xeric environments, but a random distribution in mesic environments. The low availability of resources for oviposition and the high density of gallers in xeric environments reinforce interspecific competition as an important structuring force for gall communities in these environments.

“…Indirectly, variation in leaf flushing time produces resource patches that change in quality for herbivores. For example, in seasonal environments, plants with early leaf‐flushing can accumulate more resources during an extended vegetative stage, resulting in both a greater vegetative growth and accumulation of secondary compounds, which in turn, affect herbivores performance (Costa et al., ; Fagundes et al., ; Forister, ; Yukawa, ). Thus, intrapopulational variation in leaf plant phenology can affect plant quality, preference, and incidence of herbivorous insects on plants (Dahlgren, Zeipel, & Ehrlén, ; Nord, Shea, & Lynch, ; Parachnowitsch, Caruso, Campbell, & Kessler, ).…”

“…In fact, plants with early‐leaf flushing are usually more attacked by sessile herbivores such as gall‐inducing insects, because those plants provide more resources and longer time for herbivore development (Forister, ; Yukawa & Akimoto, ). In contrast, herbivores with a short larval phase can better adapt to plants with late leaf flushing (Fagundes et al., ; Singer & Parmesan, ). Different races of the same herbivore species can use temporary resource patches in different ways (Mopper, ).…”

The dynamics of occurrence of target organs in plant populations produces windows of opportunity that directly and indirectly affect the structure of herbivore communities. However, mechanisms that drive herbivore specialization between resource patches are still poorly known. In this study, we tested three hypotheses related to variation in host plant phenology and community structure (i.e., composition, richness, and abundance) of gall‐forming species: (a) plants with early leaf‐flushing in the season will have greater vegetative growth and high contents of secondary chemical compounds; (b) gall‐inducing insect community structure changes among temporary resource patches of the host; and (c) interspecific competition is a probable mechanism that drives gall‐inducing insect community structure on Copaifera langsdorffii. We monitored daily a total of 102 individuals of the super‐host C. langsdorffii from August 2012 to May 2013, to characterize the leaf flushing time of each host plant. The leaf flushing time had a positive relationship with the number of folioles per branch and a negative relationship with branch growth. We sampled a total of 4,906 galls belonging to 24 gall‐inducing insect species from 102 individuals of C. langsdorffii. In spite of some gall‐inducing species presented high abundance on early leaf‐flushing plants, direct and indirect effects of plant phenology on galling insect abundance was species dependent. At the community level, our study revealed that the quality and quantity of plant resources did not affect the richness and abundance of gall‐inducing insects associated with C. langsdorffii. However, the richness and composition of gall‐inducing species varied according to the variation in leaf flushing time of the host plant. The results of null model analysis showed that galls co‐occurrence on C. langsdorffii trees differ more than expected by chance and that interspecific competition can be one potential mechanism structuring this gall‐inducing insect community.

O conhecimento advindo da fenologia vegetal em ecossistemas naturais promove o entendimento da biodiversidade, produtividade, organização das comunidades vegetais e sobre as interações das plantas com a fauna, sendo de grande importância em programas de conservação. Entretanto, informações fenológicas de algumas espécies são insuficientes, este é o caso de Qualea multiflora Mart. Diante do exposto, este estudo teve o objetivo de descrever a sua fenologia reprodutiva e vegetativa em fitofisionomia de Cerradão, Estado de Goiás, Brasil. Para tal, foram marcados 15 indivíduos que foram visitados mensalmente entre julho de 2016 e junho de 2018 e os eventos reprodutivos (botão floral, antese, fruto imaturo e fruto maduro) e vegetativos (broto foliar, folha jovem, folha adulta e senescência) foram registrados. A intensidade e sincronia foram avaliadas e testada a sazonalidade e correlação de Spearman da fenologia com variáveis climáticas locais. A floração ocorreu na transição do período seco para o chuvoso e durante as chuvas. A frutificação foi registrada durante todos os meses de estudo e a maturação dos frutos na época mais seca. A brotação foliar, produção de folhas e senescência ocorreram na maioria dos meses de observação, com maior intensidade em meses secos e quentes. A folhagem adulta esteve presente durante todo o estudo. Este estudo evidencia que mesmo que Q. multiflora apresente comportamento fenológico semelhante ao já encontrado na literatura para espécies arbóreas do cerradão, há algumas particularidades, principalmente no corpo vegetativo. Palavras-chave: floração; frutificação; pau-terra-liso; sazonalidade; sincronia. REPRODUCTIVE AND VEGETATIVE PHENOLOGY OF Qualea multiflora MART. IN CERRADÃO. Knowledge of plant phenology in natural ecosystems promotes the understanding of biodiversity, productivity, organization of plant communities, and interactions between plants and fauna, being of great importance in conservation programs. However, phenological information of some species is insufficient, which is the case of Qualea multiflora Mart. In this context, this study describes reproductive and vegetative phenology
