Microsatellite markers reveal genetic diversity and population structure of Portunus trituberculatus in the Bohai Sea, China.
Article in Scientific reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The swimming crab, Portunus trituberculatus, is one of the main aquaculture species in Chinese coastal regions due to its palatability and high economic value. To obtain a better understanding of the genetic diversity of P. trituberculatus in the Bohai Sea, the present study used 40 SSR loci to investigate the genetic diversity and population structure of 420 P. trituberculatus individuals collected from seven populations in the Bohai Sea. Genetic parameters revealed a low level of genetic diversity in the cultured population (SI = 1.374, He = 0.687, and PIC = 0.643) in comparison with wild populations (SI ≥ 1.399, He ≥ 0.692, and PIC ≥ 0.651). The genetic differentiation index (Fst) and gene flow (Nm) ranged from 0.001 to 0.060 (mean: 0.022) and 3.917 to 249.750 (mean: 31.289) respectively, showing a low differentiation among the seven populations of P. trituberculatus. Population structure analysis, phylogenetic tree, and principal component analysis (PCA) demonstrated that the seven groups of P. trituberculatus were divided into four subpopulations (K = 4), but the correlation between genetic structure and geographical distribution was not obvious. These results are expected to provide useful information for the fishery management of wild swimming crabs.
