Diversity and Distribution Patterns of Insects in Nigeria: A GBIF-Based Appraisal.
Article in Ecology and evolution, 2026. 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
Insects provide essential ecosystem services and are key indicators of ecosystem health. Their diversity in Africa is estimated to be high, but they are poorly documented in many African countries, such as Nigeria. In this study, we used insect occurrence records from the Global Biodiversity Information Facility (GBIF) database to investigate and examine insect diversity and distribution patterns across Nigeria's major biomes. We analysed 49,854 records from the GBIF and found 19 orders, 305 families, 2515 genera and 5880 species. However, the richness estimator analysis suggests that current records only represent ~21% of the true insect diversity in Nigeria. We also show that diversity differs between biomes and follows a latitudinal pattern. Overall, our findings reveal geographic and taxonomic gaps, and highlight the need to prioritise under-represented taxa and locations to improve biodiversity assessment and conservation planning. We suggest that the current state of Nigeria's insects reflects a dire situation that needs addressing through local and international collaboration facilitated by extensive government support.
