Summary: This study analyzed the differences in head width and prementum size among Cordulegaster boltonii larvae from 18 populations in the Iberian Peninsula. The results showed that prementum length was greater in southern populations compared to northern ones, and latitude and altitude were the key factors explaining these differences.

Summary: The structure of ecological communities is influenced by factors like niches, dispersal limits, and evolutionary history of species. Recent research in Brazilian Amazonia on adult damselflies and dragonflies showed that species with similar responses to environmental gradients tend to be more closely related phylogenetically and morphologically. This suggests that both morphology and phylogeny play important roles in determining species' responses to environmental changes.

Summary: Dragonflies and damselflies are a charismatic, medium-sized insect order with a unique potential for comparative research. A new study provided an ordinal hypothesis of classification based on high throughput data, revealing the monophyly of all three suborders but also highlighting unresolved portions of the topology and potential evolutionary scenarios like incomplete lineage sorting and introgression. The study proposed an updated odonate classification with the addition of new families and reinstatement of two others, while also identifying problematic taxonomic groupings for future examination to improve the current phylogenetic hypothesis.

Summary: Odonates are important insects in freshwater food chains and their distribution and molecular information in Brazil's Paraiba state is limited. In this study, a survey was conducted in two locations and a DNA barcode database was built. New species records were reported and the use of COI was found helpful in identifying and delimiting species.

Summary: Human activities have significant impacts on the structure, dynamics, and energy flow of aquatic ecosystems. Damming rivers in Brazil, a common anthropic activity, alters solar incidence, water flow, and water temperature, which in turn affects the fauna in waterbodies. Odonata, due to their sensitivity to environmental changes, can serve as indicators of these impacts. This study evaluated the effects of damming on odonate community structure by sampling two ecologically distinct sites in Brazil. The results showed that damming led to a significant change in species composition and reduced local fauna diversity in the impacted reservoir landscape. Additionally, two bioindication ratio tools based on taxonomic categories effectively reflected the extent of damming impacts. The findings highlight the importance of considering the effects of damming on aquatic ecosystems and the potential use of Odonata as indicators of these impacts in conservation and management efforts.

Summary: The study aimed to assess how environmental changes affect Odonata larval assemblages in streams in the eastern Amazon. The results showed that regional- and local-scale environmental changes are important predictors of the Odonata larval assemblage structure. Environmental conditions within the stream channel are crucial for maintaining Odonata larval assemblages.

Summary: A new species of dragonfly, Pseudocymatophlebia bisecta sp. nov., was discovered in China's Lower Cretaceous period. This species is characterized by its dense wing venation and an increased number of cells in specific regions. It also differs from other species in the same genus by having a two-celled discoidal triangle in both fore- and hind wings. Additionally, a revision of the genus Pseudocymatophlebia has been proposed.

Summary: This study compared the differences between highway stormwater ponds and surrounding ponds using Odonata as a bioindicator. The results showed that stormwater ponds had higher Odonata richness, beta-diversity, and conservation values, but their taxonomic distinctness was lower compared to surrounding ponds. The trophic state, relative tree shading, and fish stocking intensity were found to be the most important factors affecting the differences between the two pond types. The study highlights the potential of stormwater ponds to enhance biodiversity in non-urban areas and suggests management practices to enhance their conservation function.

Summary: Anthropic activities can affect aquatic communities and reproductive behavior of species. Functional characteristics play a vital role in species occurrence and respond differently to human impacts in the Eastern Amazon. Altered environments favor heliothermic and exophytic species, while preserved environments support species with endophytic and epiphytic oviposition and ectothermic thermoregulation. Morphologically, altered environments favor medium to large individuals, whereas preserved environments may favor smaller and/or specialized species.
