“…In other research Dermaptera insects can access the canopy of palm trees Attalea phalerata Mart. which can reach seven meters in height (SANTOS et al, 2003). Like fennel plants grow between 0.5 and 2m M. arachidis potentially can access fennel plants until the top as we saw in other observations.…”

ABSTRACT. Ecological aspects of a community of Araneae (Arthropoda, Arachnida) at the canopy of the palm Attalea phalerata Mart. (Arecaceae) in the Pantanal of Poconé, Mato Grosso, Brazil. Six palm trees of Attalea phalerata were sampled during the aquatic phase (high water) in the Pantanal of Mato Grosso (February 2001) using canopy fogging. The objective was to evaluate the composition, spatial distribution, behavioural guilds, biomass and seasonality of the community of Araneae at the crowns of these palm trees, which form monospecific stands that are typical of this region. A total of 1,326 spiders was collected in the 99 m 2 sampling area (13.4 + 8.2 individuals/m 2 ), representing 20 families, of which Salticidae and Araneidae were the most abundant. The total biomass of 704 spiders from three palm trees was 0.6172 mg dry weight (0.0123+ 0.04 mg/m 2 ). In terms of behaviour guilds, ten groups were found, demonstrating the coexistence of many different groups in the same habitat. Members of the Salticidae, Oonopidae and Ctenidae were the dominant hunters and members of Araneidae and Dictynidae, the dominant orb-weavers. Analysis of the spatial distribution showed that the greatest abundance of spiders occurred in the central region of the crown, which probably provided access to the large number of resources available there. A comparison of these results with the ones obtained in the terrestrial phase (low water) revealed a seasonal difference that is influenced by the flood pulse in which there was a difference in the composition of the families in the high and low water. KEYWORDS.Araneae; guilds; palms; Pantanal; tree crowns. RESUMO. Seis palmeiras de Attalea phalerata foram amostradas durante a fase aquática (cheia) no Pantanal de MatoGrosso (fevereiro/2001), utilizando-se a metodologia de nebulização de copas "canopy fogging". Este estudo objetivou avaliar a composição, distribuição espacial, guildas comportamentais, biomassa e sazonalidade da comunidade de Araneae em copas dessa palmeira que forma adensamentos monodominantes, típicos nessa região. Um total de 1326 aranhas foram coletadas em 99 m² de área amostral (13,4 + 8,2 indivíduos/m 2 ), representando 20 famílias, sendo Salticidae e Araneidae as mais abundantes. A biomassa total de 704 aranhas em três palmeiras correspondeu a 0.6172 mg de peso seco (0,0123+ 0,04 mg/m 2 ). Dez guildas comportamentais demonstraram a coexistência de diferentes espécies em um mesmo habitat. Representantes de Salticidae, Oonopidae e Ctenidae dominaram entre as caçadoras, e Araneidae e Dictynidae, dentre as tecelãs. A análise de distribuição espacial demonstrou que a maior abundância de aranhas ocorreu na região central da copa, provavelmente devido à quantidade de recursos disponíveis nesse local. A comparação desses resultados com aqueles obtidos durante o período de seca, demonstra diferenças sazonais influenciadas pelo pulso de inundação, principalmente com relação à composição das famílias amostradas entre os períodos de seca e cheia.

Premise: Flower damage caused by florivores often has negative consequences for plant reproduction. However, the factors affecting plant-florivore interactions are still poorly understood, especially the role of abiotic factors and interspecific variation in florivory within ecosystems. Thus, the patterns of florivory levels and its consequences for plant communities need to be investigated further. Methods: We assessed the influence of abiotic factors related to climatic seasonality, of phylogenetic relationships among plants, and of functional attributes associated with attractiveness to pollinators on florivory incidence and intensity in the Pantanal, the world's largest tropical wetland. Between December 2020 and November 2021, the percentage of flowers attacked (incidence) and petal area removed (intensity) by florivores were examined in 51 species from 25 families, considering flowering season, the substrate where the plants occur, and flower attributes as potentially determining factors on florivory levels. Results: Phylogeny and environmental factors did not have a significant influence on florivory. The only determinant of interspecific variation in florivory incidence and intensity was flower size, where larger flowers experienced higher florivory levels regardless of season and substrate, while flower arrangement and color were not significant factors. Conclusions: Our study is one of the first to estimate the community-wide effects of biotic and abiotic factors on both the incidence and the intensity of florivory. The magnitude of this plant-florivore interaction may reduce reproductive success and entail selective pressures on plant attractiveness to pollinators.
