“…The HiSSE (Beaulieu & O'Meara, 2016) and MuHiSSE (Nakov et al, 2019) allow a sophisticated test that acknowledges that additional unknown factors might be contributing to species diversification. We propose body pigmentation, dimorphism, territoriality, genital differentiation as other possible factors worth testing in future species diversification studies (Cordero‐Rivera & Rivas‐Torres, 2019; Grether, 2019; Outomuro et al, 2013; Santos & Machado, 2016).…”

1. In dragonflies, species richness shows a marked variation between lineages. Species diversification in this lineage has been linked with habitat variation, but the role of other factors, such as wing pigmentation, arguably one of the most conspicuous traits in dragonflies, have not yet been explored.2. In this study, using novel methodology that takes into account state-dependent speciation, extinction models, and ancestral reconstruction, we investigate the role of wing pigmentation (present/absent) in conjunction with habitat variation (lentic/ lotic), to unveil the drivers of species diversification in dragonflies.3. We found that wing pigmentation is associated with a marginal increase in diversification compared to unpigmented lineages. Inhabiting a lentic habitat is associated with higher diversification rates. When considering both factors in a single model, lentic environments are associated with higher diversification compared to lotic habitats regardless of pigmentation status. In contrast with results across the whole tree, in lotic environments, wing pigmentation is associated with marginally higher diversification rates compared to non-pigmented species. Ancestral state reconstruction revealed that the last common ancestor of dragonflies was most likely non-pigmented and lived in lotic habitats. 4. Our study provides evidence that wing pigmentation in conjunction with habitat has an important influence on dragonflies species diversification, with habitat being a better differentiator than wing pigmentation.

“…Sexual maturity brings several changes, mainly those related to predatory and reproductive behaviors. Males that allocated their energy to prey capture during the larval stage, now adopt a reproductive life strategy as adults, with complex courtship displays (Gibbons & Pain, 1992; Guillermo‐Ferreira et al, 2015), territorial defense (Grether, 2019), and mate acquisition and guarding (Thornton & Switzer, 2015). Adult females need to develop skills to select the best mates (Pena‐Firme & Guillermo‐Ferreira, 2020) by identifying their ideal male patterns of color and behavior, as well as finding and choosing adequate oviposition sites (Guillermo‐Ferreira & Del‐Claro, 2011; Rodrigues et al, 2019).…”

Discussion regarding the gaps of knowledge on Odonata is common in the literature.Such gaps are even greater when dealing with basic biological data for biodiverse environments like the Amazon Rainforest. Therefore, studies that address, classify, and standardize functional traits allow the elaboration of a wide range of ecological and evolutionary hypotheses. Moreover, such endeavors aid conservation and management planning by providing a better understanding of which functional traits are filtered or favored under environmental changes. Here, our main goal was to produce a database with 68 functional traits of 218 Odonata species that occur in the Brazilian Amazon. We extracted data on behavior, habit/habitat (larvae and adults), thermoregulation, and geographic distribution from 419 literature sources classified into different research areas. Moreover, we measured 22 morphological traits of approximately 2500 adults and categorized species distributions based on approximately 40,000 geographic records for the Americas. As a result, we provided a functional matrix and identified different functional patterns for the Odonata suborders, as well as a strong relationship between the different trait categories. For this reason, we recommend the selection of key traits that represent a set of functional variables, reducing the sampling effort. In conclusion, we detect and discuss gaps in the literature and suggest research to be developed with the present Amazonian Odonata Trait Bank

“…Territorial fights are costly, primarily because they can result in males losing their territories and priority of access to ovipositing females (territory possession confers a three-fold mating advantage; Grether 1996;Drury & Grether 2014). Damselfly fights also have energetic and physiological costs (reviewed in Suhonen et al 2008;Vieira and Peixoto 2013;Córdoba-Aguilar and González-Tokman 2014;Kemp 2018;Grether 2019), and fights that do not immediately result in territory turnover likely reduce the ability of the residents to win future fights. Thus, selection may favor divergence in microhabitat use because this reduces the probability of interspecific encounters and therefore the frequency of interspecific fights.…”

Mechanisms of reduced interspecific interference between territorial species

Interspecific territoriality has complex ecological and evolutionary consequences. Species that interact aggressively often exhibit spatial or temporal shifts in activity that reduce the frequency of costly encounters. We analyzed data collected over a 13-year period on 50 populations of rubyspot damselflies (Hetaerina spp.) to examine how rates of interspecific fighting covary with fine-scale habitat partitioning and to test for agonistic character displacement in microhabitat preferences. In most sympatric species, interspecific fights occur less frequently than expected based on the species’ relative densities. Incorporating measurements of spatial segregation and species discrimination into the calculation of expected frequencies accounted for most of the reduction in interspecific fighting (subtle differences in microhabitat preferences could account for the rest). In 23 of 25 sympatric population pairs, we found multivariate differences between species in territory microhabitat (perch height, stream width, current speed, and canopy cover). As predicted by the agonistic character displacement hypothesis, sympatric species that respond more aggressively to each other in direct encounters differ more in microhabitat use and have higher levels of spatial segregation. Previous work established that species with the lowest levels of interspecific fighting have diverged in territory signals and competitor recognition through agonistic character displacement. In the other species pairs, interspecific aggression appears to be maintained as an adaptive response to reproductive interference, but interspecific fighting is still costly. We now have robust evidence that evolved shifts in microhabitat preferences also reduce the frequency of interspecific fighting.
