Forest islands sustain more temporally stable insect metacommunities in a heterogeneous tropical mountaintop landscape.
Article in npj biodiversity, 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
We evaluated how habitat type influences community temporal dynamics in a heterogeneous tropical mountain landscape. We sampled ants, dung beetles, and fruit-feeding butterflies across two mountaintop habitats: campo rupestre and forest islands in the Southern Espinhaço Range, Brazil. We quantified temporal dynamics by assessing variations in species richness across sampling years and in species composition, focusing on species gains and losses. Species richness did not differ between environments and most species were unique to either campo rupestre or forest islands. We found no consistent pattern of species gains or losses among insect communities or habitat types, with such temporal dynamics being more prevalent for butterflies in the campo rupestre. In the campo rupestre, recent periods were dominated by colonization-driven homogenization following widespread species losses. In forest islands, extirpations prevailed for ants, colonizations for butterflies, and processes were balanced for dung beetles. The campo rupestre showed greater temporal dynamics in species richness and composition, particularly for butterflies and dung beetles, resulting in more frequent species gains. Habitat type shapes the temporal dynamics of insect communities in heterogeneous tropical mountaintop landscapes. Forest islands sustain more temporally stable insect metacommunities, while open environments and more mobile organisms have greater temporal dynamics.
