“…Of note, Miconia flowers are an important resource for pollen-collecting bees, wasps, beetles, flies, moths and hummingbirds (Kriebel and Zumbado, 2014;Brito et al, 2016Brito et al, , 2017b. Moreover, Miconia species are known as hosts of many specialized herbivores, including leaf-chewing lepidopteran larvae (Badenes-Pérez et al, 2010;Scherrer et al, 2010), twig girdler beetles (Paulino-Neto et al, 2005;Paro et al, 2014), seed-feeding carabid beetles (Paarmann et al, 2002), sap-sucking treehoppers (Lopes, 1996;Chacón-Madrigal et al, 2012;Swing, 2012;Alfaro-Alpízar et al, 2020), fruit-galling insects (Centrella andShaw, 2010, andleaf-galling nematodes (Santos et al, 2012;Viana et al, 2013), among others. Therefore, we highlight the need for further studies addressing their importance for primary consumers other than frugivores, as well as their role in maintaining biodiversity and ecosystem functioning, while facilitating habitat connectivity and providing ecosystem services across Neotropical ecoregions.…”

Background and aims Much of our understanding of the ecology and evolution of seed dispersal in the Neotropics is founded on studies involving the animal-dispersed, hyper-diverse plant clade Miconia (Melastomataceae). Nonetheless, no formal attempt has been made to establish its relevance as a model system or indeed provide evidence of the role of frugivores as Miconia seed dispersers. Methods We built three Miconia databases (fruit phenology/diaspore traits, fruit–frugivore interactions, and effects on seed germination after gut passage) to determine how Miconia fruiting phenology and fruit traits for >350 species interact with and shape patterns of frugivore selection. In addition, we conducted a meta-analysis evaluating the effects of animal gut passage/seed handling on Miconia germination. Key Results Miconia produce numerous small berries that enclose numerous tiny seeds within water-sugar-rich pulps. In addition, coexisting species provide sequential, yearlong availability of fruits within communities, with many species producing fruits in periods of resource scarcity. From 2,396 pairwise interactions, we identified 646 animal frugivore species in five classes, 22 orders and 60 families, including birds, mammals, reptiles, fish and ants that consume Miconia fruits. Endozoochory is the main dispersal mechanism, but gut passage effects on germination were specific to animal clades; birds, monkeys and ants reduced seed germination percentages, while opossums increased it. Conclusions The sequential fruiting phenologies and wide taxonomic and functional diversity of animal vectors associated with Miconia fruits underscore the likely keystone role that this plant clade plays in the Neotropics. By producing fruits morphologically and chemically accessible to a variety of animals, Miconia species ensure short and long distance seed dispersal and constitute reliable resources that sustain entire frugivore assemblages.

“…Coulson (1979) suggested that borer survival is associated with trunk diameter, as larger plants provide more resources and protection against desiccation, climate variation, and natural enemies, and support a higher number of beetles. This guild seems to respond positively to plant architecture with respect to food and offspring development (Caraglio et al, 2001;Paulino Neto et al, 2005).…”

Vertical stratification and effect of petiole and dry leaf size on arthropod feeding guilds in Cecropia pachystachya(Urticaceae)

et al. 2015

This study aimed to test for vertical stratification and the effects of dry leaf size on herbivore and predator arthropods and petiole length on insect borers in Cecropia pachystachya. The leaves were sampled in three strata: attached to the plant, suspended on the vegetation and on the ground. We detected vertical stratification only in the guild of predator arthropods associated with dry leaves, with lower richness and abundance in the attached stratum. In addition, larger leaves positively affected the insect herbivore fauna, whereas the richness and abundance of insect borers increased with petiole length. The greater isolation of leaves attached to trees relative to the surrounding vegetation likely creates greater difficulty for dispersal and colonization by non-winged predators such as spiders. Larger dry leaves provide more shelter against predators and climate variations for insect herbivores. Moreover, larger petioles increase the availability of resources and nesting sites for insect borers. These results are consistent with other studies that found a similarity in the structure of feeding guilds across vertical strata and with studies that showed an increase in species richness and abundance of free-feeding insect herbivores with increasing structural complexity of their host.Keywords: insect herbivores, bark beetles, predators, habitat complexity, resource availability.Estratificação vertical e efeito do tamanho de pecíolos e folhas secas de Cecropia pachystachya sobre guildas alimentares de artrópodes (Urticaceae) ResumoOs objetivos do presente trabalho foram testar as hipóteses de que existe estratificação vertical e efeito do tamanho de folhas secas de Cecropia pachystachya sobre artrópodes herbívoros e predadores, e efeito do tamanho dos pecíolos sobre insetos brocadores. As folhas foram amostradas em três estratos: presas à planta, caídas sobre a vegetação e no solo. Foi verificada estratificação vertical apenas para os artrópodes predadores, com menor riqueza e abundância no estrato presa. Além disso, folhas maiores afetam positivamente a fauna de insetos herbívoros, enquanto que a riqueza e abundância de brocadores aumentam com o tamanho do pecíolo. O maior isolamento das folhas presas em relação à vegetação do entorno provavelmente determina maior dificuldade de dispersão e colonização por predadores não alados, como aranhas. Folhas secas maiores oferecem maiores áreas de refúgio e abrigo contra predadores e variações climáticas para insetos herbívoros. Além disso, maiores pecíolos aumentam a disponibilidade de alimento e locais para nidificação dos insetos brocadores. Estes resultados são consistentes com estudos que encontraram uma similaridade na estrutura de guildas alimentares entre estratos verticais. Corroboram também estudos que mostram o aumento da riqueza e abundância de insetos herbívoros de vida livre com o aumento da complexidade estrutural do hospedeiro.Palavras-chave: insetos herbívoros, brocadores, predadores, complexidade do habitat, disponibilidade de recurso.

“…Longhorn beetles (Coleoptera: Cerambycidae) have a cosmopolitan distribution and feed on many woody plant species (González and Di Iorio 1997;Tavakilian et al 1997;Paulino-Neto et al 2005). They play an important role in the conversion of wood into humus (González and Di Iorio 1997;Tavakilian et al 1997;Berkov and Tavakilian 1999), but have had increasing prominence as pests of trees and shrubs (Linsley 1959;Haack et al 1997;Nowak et al 2001).…”

Cerambycid girdling and water stress modify mesquite architecture and reproduction

This study evaluated the effect of an outbreak of the cerambycid beetle, Oncideres rhodosticta, on branch growth and inflorescence production of the mesquite Prosopis glandulosa var. torreyana, and on larvae mortality in girdled branches at two sites (dry and wet) in the southern Chihuahuan Desert of Mexico. We compared stem growth responses to girdling in branches of similar sized trees from both sites over 42 months. The number of larvae per girdled branch was similar between sites, indicating similar ovipositing effort regardless of water stress. However, the proportion of dead larvae was significantly lower in trees at the dry site. On average, girdling reduced 96% of the stem length at both sites. At the end of the first year, 25% of the original stubs survived at the dry site, compared to 90% at the wet site. Girdling also broke apical dominance and allowed for the development of lateral buds from the surviving stubs, which produced many fewer branches and inflorescences at the dry site compared to the wet site, where a compact crown was developed. Water stress and girdling have a combined effect on mesquite architecture and reproduction, since more stubs died at the dry site while new branches from surviving stubs developed at the wet site, recovering the original lost biomass but changing the appearance of the tree.
