SNP genotyping of North Head and northern Sydney Long-nosed bandicoots (Perameles nasuta)
<p>Wildlife species impacted by habitat loss and fragmentation often require conservation efforts to maintain populations. Long-nosed bandicoots (<i>Perameles nasuta</i>) still persist within the highly urbanised matrix of northern Sydney (Australia). These data are from a conservation genetics project investigating population structure and genetic diversity of the North Head Long-nosed bandicoot (<em>Perameles nasuta) </em>population and individuals from surrounding suburbs throughout northern Sydney.</p> <p>The population at North Head, Sydney, is currently listed as an <i>Endangered</i> population due to its small size, apparent isolation and other threats. To support future management, we used 1,446 single nucleotide polymorphism markers (SNPs) from 167 bandicoots to: i) assess the assumption of isolation and determine if genetic structuring is present between North Head and individuals from 11 other localities in northern Sydney, and ii) investigate genetic diversity over time in the North Head population from 2002 to 2018. Analyses confirmed population structuring and genetic divergence between North Head and greater northern Sydney. Three distinct populations were identified that corresponded to geographic localities (North Head, northern Sydney and Mosman). All populations were significantly differentiated (<i>F</i><sub>ST</sub> = 0.171–0.345), suggesting local genetic drift between localities. North Head genetic diversity indices estimated between 2002 to 2018 showed relatively constant levels of allelic richness (1.90–2.00) and observed heterozygosity (<i>H</i><sub>O</sub> = 0.231–0.310) along with minor levels of inbreeding (<i>F</i><sub>IS</sub> 0.020–0.052). The identification of some individuals sampled on North Head that were assigned to other populations suggests some sporadic geneflow into the population has occurred and may have assisted with maintaining genetic diversity.</p> <p>These data were used to suggest that the North Head population is distinct from other northern Sydney populations and has relatively constant levels of genetic diversity.</p>
FIGURE 6. Both MFL and C2T in Repeatability and precision in proboscis length measurements for long proboscid flies
FIGURE 6. Both MFL and C2T measurements of Prosoeca spp. are plotted against prementum length to visualize their consistency. Lack of precision of C2T measurements (open circles) is evident from their scatter between the prementum length (1:1 line) and the MFL (closed circles). In some cases, the VRM displacement was not measured so there is no corresponding C2T measurement.
FIGURE 5 in Repeatability and precision in proboscis length measurements for long proboscid flies
FIGURE 5. Paired measurements of MFL (closed circles) and C2T (open circles) plotted against the prementum length (1:1 line) for Philoliche spp. Paired measurements are joined by vertical lines. Note that in some cases, the C2T measurement for a specimen is greater than its MFL, or less than the prementum length. Negative VRM displacement values result when the prementum is fully retracted into the head.
FIGURE 4 in Repeatability and precision in proboscis length measurements for long proboscid flies
FIGURE 4. Extent of potential proboscis extension by species/species group (labrum length mm). Bold bar indicates median, upper and lower box bounds indicate 25th and 75th percentiles (=middle 50% of data). Error bars indicate the smaller of either 1) 1.5 x interquartile range (~ 2 standard deviations), or 2) maximum/minimum value; outliners are points beyond these error bars.
FIGURE 3 in Repeatability and precision in proboscis length measurements for long proboscid flies
FIGURE 3. Morphology of the ventral rostral membrane. A and B: Close up of proximal section of the proboscis in Prosoeca ganglbaueri showing the partially extended VRM (green), labrum (LBR, part of syntrophium, blue), and prementum (orange). Note the finger-like projection of the distal end of the prementum. Because this varies in size and is often not visible, measurement of the prementum is taken from the first point the prementum is complete ventrally. C. Lateral view of disarticulated proboscis in Prosoeca ganglbaueri. D. VRM displacement of the prementum can be difficult to see except upon close examination. Here the stretched VRM has dried inconspicuously onto the syntrophium.
FIGURE 1. A in Repeatability and precision in proboscis length measurements for long proboscid flies
FIGURE 1. A. Three specimens of Philoliche gulosa showing the proboscis in various states of preservation: maximum ventral rostral membrane (VRM) displacement, moderate VRM displacement, full retraction of the prementum into the head (from top to bottom); B. Extension of the VRM changes the appearance of the proboscis length of two specimens with similar proboscis lengths (PL= prementum length, MFL=Maximum Functional length, C2T= Clypeus to tip length); C. Close up of proboscis belonging to top-most specimen in A and B above (SIM 1807B), showing the disarticulation of the syntrophium from the VRM and prementum (LBR=labrum, part of syntrophium).
