Landscape degradation drives metal bioaccumulation in bats from Atlantic Forest cacao region, Brazil.
Article in Environmental science and pollution research international, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
Agricultural landscapes worldwide are heavily sprayed with agrochemicals to increase crop productivity. These agrochemicals release bio-accumulative pollutants such as heavy metals that often persist in the environment with harmful impacts on biota. In a prime endangered Atlantic Forest biome, in Bahia, Brazil, agroforestry of cacao (Theobroma cacao) provides a livelihood for small farmers and suitable habitats for forest species. However, landscape transformation to pasture and monoculture expose vulnerable communities to scarcely evaluated pollutants with unknown effects on the health of humans and animals. We assessed the bioaccumulation of manganese (Mn), lead (Pb), and copper (Cu) by analyzing hair samples of 326 bats representing 28 species across 15 cacao agroforestry and 2 forest remnants. Bats from regions heavily disturbed by pastures and monocultures showed higher levels of Pb (41.20 µg/g) and Mn (0.44 µg/g) compared to those from areas where forest or cacao agroforestry dominates the landscape. Local grassland covers increased Pb bioaccumulation, while forest cover reduced it. Cacao agroforestry appeared to increase Cu exposure, likely due to fungicide use. This study pioneers the evaluation of heavy metal accumulation in bats inhabiting cacao agroforestry and Atlantic Forest remnants, highlighting the need for sustainable agricultural practices to protect wildlife and ecosystem health.
