Abstract Dragonflies (Odonata) are ancient and familiar insects with a deep strong cultural association humans. They have an aquatic larval stage aerial adult stage, meaning that they respond to ecological conditions in both freshwater the adjacent land surface. Currently, 16% of dragonflies threatened. Overall, face several threats, especially habitat loss, landscape transformation, pollution, altered hydrology, spread invasive alien species, as well certain geographic‐specific threats. Overarching these which can be interactive each other, is issue global climate change attendant extreme weather events. While many localised specialist species under threat, some other dragonfly mostly generalists, benefit from moderate human activities, creation high‐quality artificial ponds. As well‐researched insects, play important role protection riparian ecosystems. Dragonfly assemblages great value sentinels deteriorating environmental ecosystem recovery following restoration. similar findings on threats conservation actions emerging across world, ecosystems require targeted approaches. Above all, must included more widely general biodiversity activities policies. targets, tools model organisms for action, act potential surrogates taxa also depend high water zone quality. research has paved way address challenges, including use new technologies, we now urge strongly policy management associated terrestrial realms. This inclusion effective appeal diverse community people odonatologists (citizen professional) through policymakers managers, all whom employ contribute freshwater‐associated conservation. Finally, propose action plan focusing five points opportunities, suggest where greater freshwater/riparian world.

Abstract The various ecosystems of the Amazon biome play a vital role in maintenance biodiversity, as well providing important ecosystem services at local and global levels. Small-bodied generalists include number groups, such insects order Odonata. Given their sensitivity to environmental alterations, odonates are also valuable bioindicators quality. In this context, present study evaluated distribution diversity adult Legal Amazonia zone Brazilian state Maranhão, verify which variables most drivers structure odonate communities. To test these predictions, we sampled 27 streams along landscape gradient located hydrographic basin Pindaré River Maranhão. results indicated that alterations environment reflected recorded each site, with assemblages degraded environments having predominance more generalist species. However, some species threatened by loss habitats, primarily denser vegetation. habitat loss, particularly dense Despite this, discovery Erythrodiplax unimaculata Maranhão highlights ongoing biodiversity revelations. underscores urgent need for continuous monitoring mitigate face widespread disturbances region.

Accurate assessment of species rarity and conservation status requires an approach that integrates data-driven models with established ecological knowledge. In this study, we applied multispecies occupancy (MSO) latent factor (LFMSO) to estimate the occurrence 133 Odonata in South Korea. Using model outputs, implemented Rabinowitz framework conduct data-based assessments, which were then compared known information, including geographic ranges, habitat preferences, regional Red List statuses, citizen science observations. Our findings reveal both alignments discrepancies between these assessments traditional For example, classified as near threatened (NT) or vulnerable (VU) on generally corresponded high-rarity classifications based framework. However, significant inconsistencies identified, particularly for certain lentic traditionally considered common. These results suggest spatial biases field surveys, combined limited access data legally protected species, can impede accurate assessments. underscore need standardized survey protocols improved data-sharing policies sensitive reduce enhance reliability This is essential effective planning biodiversity management freshwater ecosystems.
