Data for: Hematology and biochemistry of critically endangered radiated tortoises (Astrochelys radiata): reference intervals in previously confiscated subadults and variability based on common techniques

Dataset for: Brenn-White M, Raphael BL, Rakotoarisoa NAT, Deem SL. 2022. Hematology and biochemistry of critically endangered radiated tortoises (Astrochelys radiata): reference intervals in previously confiscated subadults and variability based on common techniques. PLOS One. Dataset is contained in a.radiata_bloodwork.csv. Metadata and data definitions are contained in a.radiate_bloodwork_readme.txt. Dataset contains hematology and biochemistry values of 120 previously confiscated, clinically healthy subadult radiated tortoises living under human care within their native habitat at the Tortoise Conservation Center (TCC), Madagascar. To evaluate the effects of different commonly used techniques on these parameters, we compared results between two venipuncture sites (subcarapacial sinus and brachial vein) and three different WBC quantification methods (Natt and Herrick, LeukopetTM, and slide estimate). Data from tortoises removed from the final analyses due to sample quality issues are also included as frequency of sample quality issues varied by venipuncture site. See associated publication for detailed methods.

Fig. 2 in A new lineage of Galapagos giant tortoises identified from museum samples

Fig. 2 Statistical parsimony haplotype network of the mitochondrial control region (668 bp) for 129 contemporary individuals from San Cristóbal and six historical specimens collected in 1906, as well as 28 representative haplotypes from the other species of Galapagos giant tortoise. The name of the island where each species occurs is labeled with capital letters, with current taxonomy in italics. Haplotypes are represented as black circles on the network, the size of the circle is proportional to the frequency of the haplotype in the analysis. Open circles represent unsampled, hypothesized haplotypes, and hash marks indicate a single mutational change. Reticulations reflect uncertainty in relationships, or homoplasy.

Fig. 4 Barplots depicting K in A new lineage of Galapagos giant tortoises identified from museum samples

Fig. 4 Barplots depicting K = 2 for the STRUCTURE analysis using the SNP (12 192 loci) and microsatellite (21 loci) genotypes for the contemporary San Cristóbal population (n = 64). Each bar represents an individual and the proportion of the bar that is each color represents the membership of that individual to the two clusters. The order of individuals is the same in both plots, black boxes around bars highlight individuals with a greater than 0.4 discrepancy in assignment proportions between the analyses.

Fig. 3 Bayesian Inference maximum clade credibility cladogram showing relationships among the San Cristóbal historical samples from the cave and collected alive in 1906, and a reference dataset of 93 Galapagos giant tortoise haplotypes and three outgroups based on the mitochondrial control region (alignment length 718 bp), estimated using BEAST with a strict clock and Birth Death tree. The numbers on the branches are the posterior probability support values. § indicates the C. chathamensis type specimen. The name of the island where each clade is found is in capitals, with current taxonomy in italics.
