Odonata Diversity and Ecological Thresholds in Protected Areas of the Brazilian Amazon.
Article in Neotropical entomology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The establishment of conservation units (CUs) aims to preserve biodiversity, yet these areas are under great anthropogenic pressure, particularly from logging, mining, and cattle ranching. Considering this context, our study assesses the importance of the protected area (National Park) and habitat integrity using the Habitat Integrity Index (HII) for conserving Odonata assemblages. Our hypothesis is that (1) the sites within the national park would have higher HII scores and greater Zygoptera diversity metrics (species diversity, abundance, proportions, and composition) compared to the scores of the sites outside the park; and (2) considering the habitat integrity of the streams, Anisoptera and Zygoptera serve as indicators, with the former associated with lower scores and the latter with higher scores. We sampled 25 streams (both within and outside) of the Jamanxim National Park, identifying 43 species of Odonata, including 16 Anisoptera and 27 Zygoptera. Streams outside the national park harbored the highest number of exclusive Anisoptera and Zygoptera species. Linear models revealed a significant negative correlation between habitat integrity and Anisoptera abundance only. Moreover, significant differences in Anisoptera abundance were observed between streams within and outside the national park, along with distinct heterogeneity in Anisoptera species composition. The decrease in Anisoptera abundance with increasing habitat integrity may be attributed to their preference for open areas for thermoregulation. Conversely, the positive response of Zygoptera species to habitat integrity underscores their reliance on more conserved environments, enhancing our understanding of their ecological requirements. These results reinforce the importance and efficiency of Odonata as a bioindicators of environmental quality and integrating the order into aquatic monitoring programs alongside the HII, provides a straightforward and objective measure of environmental disturbance.
