Resumo: | The maintenance of species diversity is a comple xphenomenon whose determinant factors can act in many spatial scales from local habitats to the regional level. We analyzed the habitat use by frugivorous insects in three categories of Psidium guajava fruits. We found 2,140 individuals of 22 morphospecies, of which Diptera (6 spp.), Hymenoptera (6 spp.), and Coleoptera (5 spp.) were the richest orders. Diptera was the most abundant order, with 93% of the total collected individuals (1,986 ind.). The greatest richness occurred in the fruits on the litter: 19 spp., contrasting with 7 spp. in ripe fruits and 2 spp. in unripe fruits on the tree. Diversity was significantly higher in fruits on the litter. Similarity was greatest between unripe and ripe fruits on the tree (0. 50). Abundance (r2 = 0.08; r = 0.29, p = 0.00) show a positive and significant relation with total volume of the all fruit categories Abundance (Log10) in unripe fruits correlated positive and significantly with total diameter of these fruits (r2 = 0.12; r = 0.35, p = 0.04). Variations in invertebrate richness, abundance, diversity, and density in the three fruit categories suggest different community establishment restriction levels. The physical and biological change gradients in the P. guajava fruits represent a heterotrophic succession. The temporal and spatial position of the fruits promotes variations in their physical and chemical properties. This variation in resource quality creates microhabitat heterogeneity and makes the presence and co-existence of many species of frugivorous invertebrates possible. |

Foram analisadas neste estudo o uso de três categorias de frutos de Psidium guajava como habitats para insetos frugívoros. Foram encontrados 2.140 indivíduos de 22 morfo-espécies. Díptera (6 spp.), Hymenoptera (6 spp.), e Coleoptera (5 spp.) foram as ordens mais ricas. Díptera foi a ordem mais abundante, contribuindo com 93% o total dos indivíduos coletados (1.986 ind.). A maior riqueza (19 spp) foi encontrada em frutos presentes no chão (serrapilheria), contrastando com frutos maduros presentes nas árvores, onde foram encontradas 7 spp. e frutos verdes 2 spp. A diversidade foi significativamente mais elevada nos frutos na serrapilheira. A similaridade foi maior entre frutos maduros e verdes presentes na árvore (0. 50). A abundância (r2 = 0.08; r = 0.29, p = 0.00) relacionou-se positiva e significativamente com o volume do conjunto de frutos. A abundância (Log10) encontrada nos frutos verdes foi correlacionada positiva e significativamente com o diâmetro total (r2 = 0.12; r = 0.35, p = 0.04). As variações na riqueza, na abundância, na diversidade, e na densidade dos insetos nas três categorias de frutos sugerem níveis diferentes de limitação ao estabelecimento destas comunidades. O gradiente de mudanças físicas e biológicas nos frutos de P. guajava. representa uma sucessão heterotrófica. A posição temporal e espacial dos frutos promove variações em suas propriedades físicas e químicas. Esta variação interfere na qualidade do recurso criando uma heterogeneidade de microhabitats que possibilita a presença e a coexistência de muitas espécies de insetos frugívoros.Universidade do Vale do Rio dos Sinos (Unisinos)2020-04-18T02:38:08Z2020-04-18T02:38:08Z2011-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSILVA, M.
