Sharp decrease of genetic variation in two Spanish localities of razor clam Ensis siliqua: natural fluctuation or Prestige oil spill effects?
Article in Ecotoxicology (London, England), 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Pollution is one of the main concerns in marine ecosystems nowadays. Environmental anthropogenic-mediated toxicants may affect genetic diversity both at the individual and ecosystem levels and may also alter the genetic structure of populations. This study examined the temporal pattern of genetic diversity among populations of the benthic bivalve Ensis siliqua in two locations of Galicia, following the Prestige oil spillage. On November 13, 2002 the oil tanker Prestige sank at 240 km from Galician coast and 63,000 tonnes of heavy fuel were released to the marine environment. E. siliqua samples were sampled between 2001 and 2006. Genetic variation was assessed by means of Random Amplification of Polymorphic DNA (RAPD). A significant decrease in genetic diversity was observed for the 2006 samples. Nei's genetic distance, fixation index (PhiPT), and PCA values also supported differences in the 2006 samples. We hypothesize that the temporal genetic variation observed in E. siliqua populations is due to a strong effect of genetic drift caused by a reduction in population size and that the indirect effects of the Prestige spill possibly caused this reduction.
