Excel file contains 4 sheets. First sheet titled Adult Tiger snakes contains field data collected on Adult Tiger snakes (sex, body mass and snout-vent length). Sheet titled Mothers litters and neonates contains laboratory and museum data about reproductive output in female tiger snakes for several populations. For each female is given birth date, mean litter body mass (calculated average body mass for all neonates in a given litter), mean litter svl (calculated average snout vent length for all neonates in a given litter), and mean litter jaw (calculated average jaw length for all neonates in a given litter). Sheet titled Prey contains data collected in Museum collection for prey available at each study site. Latin names are given with body mass and maximum circumference of each prey item. Sheet titled Growth experiment contains experimental data on growth rate and food consumption in neonate Tiger snakes from several populations. Headings indicate for each mother its population of origin, neonate identification number, birth date and morphometrics at birth. Body mass and snout vent length are recorded every two months until the end of the experiment. Column titled Total growth in body mass indicates the difference in body mass between the start and the end of the experiment. The two last columns are Total food (total amount of food consumed by each neonate over the course of the experiment) and Length of experiment (total duration of the experiment). Conversion rates were calculated (column titled Increase in body mass per g of food) and daily growth rates in body mass (increase in body mass in mg per day). Similar calculation were made for snout vent length (increase in svl per g of food; increase in svl in mm per day)

Multidimensional scaling plot of genetic distance between <i>Notechis scutatus occidentalis</i> individuals from Perth, Western Australia.

Each population has been given a unique icon. Axis one explained 15.1% and axis one explained 9.4% of the total variance.</p

Hierarchical clustering dendrogram representing genetic distance relationships between <i>Notechis scutatus occidentalis</i> populations around Perth, Western Australia.

Calculated using 4688 single-nucleotide polymorphisms from across the genome. Note that these relationships do not necessarily reflect a true phylogeny. (TIF)</p

Pairwise values of population genomic differentiation (<i>G</i>″_ST) of <i>Notechis scutatus occidentalis</i> around Perth, Western Australia.

Hierarchical population genomic structure of <i>Notechis scutatus occidentalis</i> around Perth, Western Australia.

Unique colours in each panel represent an ancestral cluster. Black points indicate sampling sites. The dashed line represents the Swan/Canning River systems, while the dashed ring outlines Carnac and Garden Islands. (TIF)</p

Spatial autocorrelation of multilocus genotypes for <i>Notechis scutatus occidentalis</i> from Perth, Western Australia at five distance classes.

Cluster indicates the population used for analysis. Global is all mainland snakes, Northern and Southern are the populations either side of the Swan/Canning River system. The probability value at each distance class shows the proportion of permuted r values greater than the observed value in that distance class, based on 999 permutations of the SNP by sample matrix.

Admixture bar plot comparing population structure in <i>Notechis scutatus occidentalis</i> from Perth, Western Australia.

Each tick mark on the x-axis represents an individual snake, which are grouped by sampling locations. The dashed line represents the biogeographic barrier of the Swan/Canning Rivers separating the northern and southern sampling localities. The y-axis represents the fraction of individuals’ genome that originates from a particular ancestral population, each of which has been given a unique colour. (TIF)</p
