“…AIC, Akaike information criterion; NS, non-significant; significance level: *, P < 0.05; **, P < 0.01; ***, P < 0.001. The temporal dynamics reported in this study (butterfly peaks in the wet season and in the T.wd) coincide with the abundance peaks of tropical insects (Brown 1991;Wolda 1992;DeVries et al 1997DeVries et al , 2011 and with the Lepidoptera abundance peaks previously reported in the Cerrado Biome (Pinheiro et al 2002;Silva et al 2011b). The effect of weather conditions (air temperature and relative air humidity), natural enemies, and food resource availability are several factors that potentially explain the temporal dynamics observed (Morais et al 1999;Silva et al 2011b;Freire et al 2014).…”

“…Moreover, this biome has an intense dry season that imposes difficulties on the animal communities present (Marquis et al 2002). Water availability is one of the most important factors affecting plant development and flower/fruit phenology patterns, both of which, in turn, influence the temporal dynamics of associated animal communities, especially insect communities (Pinheiro et al 2002;Silva et al 2011b).…”

“…In Central Brazil, the transition period between the dry and wet seasons (Sep-Nov) corresponds with a peak in insect abundance (Silva et al 2011b). However, this pattern may change depending on the insect order (Pinheiro et al 2002;Silva et al 2011b) or the stage of insect development.…”

“…However, this pattern may change depending on the insect order (Pinheiro et al 2002;Silva et al 2011b) or the stage of insect development. For example, Coleoptera and Lepidoptera are abundant in the wet season and generally respond positively to an increase in air temperature and precipitation (Silva et al 2011b), Hymenoptera peak in the late dry season (Pinheiro et al 2002;Silva et al 2011b), and Lepidoptera larvae are abundant in the first half of the dry season (Morais et al 1999). Other orders like Orthoptera, Hemiptera, and Diptera occur homogeneously through the year (Pinheiro et al 2002).…”

Abstract. Distribution of the most diverse groups of insects is highly related to the structural complexity of the plant community, and increasing complexity, in turn, correlates with increasing diversity, richness and abundance of insects. As such, this study aims to examine the relationship between environmental heterogeneity and the richness, abundance and trophic guilds of insects. The study was conducted in the Serra da Bodoquena, Mato Grosso do Sul, Brazil. Samples were collected using an entomological net, and analysis of the distribution of functional groups along the environmental gradient was performed by direct ordering. The richness and abundance of insect species differ among the different vegetation types, such as clean pasture or cerrado. Using a functional Heterogeneity Index (HI), generalist groups showed a wide distribution, while more specialized groups were restricted to more structurally complex environments.

1. Environmental changes are increasingly frequent, resulting in adverse impacts on biodiversity. These effects are more harmful when superimposed on areas of high biodiversity such as the Amazon region, in which the gaps in knowledge of the number of existing species and how they are distributed. This article reviews the known geographical distributions of Ephemeroptera in theBrazilian Amazon based on the current uneven sampling effort to identify which species and biodiversity hotspots are poorly protected, and where more work is required to address the conservation needs of this group.3. A sampling effort index was created to identify which areas have the highest potential mayfly richness and the greatest concentration of knowledge gaps. The mayfly records were combined with environmental variables to generate predictive models of the areas suitable for mayflies using species distribution modelling, and species that lack protection in conservation units and indigenous territories were indicated as priorities for future inventories. Caenis pflugfelderi, Microphlebia surinamensis, Tricorythopsis pseudogibbus and Tricorythodes sp. nov.were identified as threatened in the Brazilian Amazon given that they were recorded in an unprotected area of intense land use with a restricted potential distribution.4. Mayflies have been recorded in only 5% of the Brazilian Amazon biome. The model indicated a greater diversity in the northern and north-eastern Amazon.The sampling effort index indicated a total area of 46,225 km 2 in mayfly biodiversity not protected by conservation units or indigenous territories.5. This study raises awareness of the importance of intensifying studies of Ephemeroptera in the Brazilian Amazon, and demonstrates that the conservation units or indigenous territories do not protect many species.
