FIGURE 4. A in Molecular phylogeny of Australian Gehyra (Squamata: Gekkonidae) and taxonomic revision of Gehyra variegata in south-eastern Australia
FIGURE 4. A. Metaphase karyotypes of the two chromosomal forms occurring in the Flinders Ranges, South Australia: G. lazelli (2n=44f), SAMAR52012, Warden Hill, and G. variegata (2n=40a), SAMAR51962, Moosha Bore. Boxes in B show the two chromosome pairs (5 and 7) that King (1979) suggested were fusion products from a primitive 2n=44 kartyotype like that shown in A.

FIGURE 6 in Description and molecular phylogeny of Tethya leysae sp. nov. (Porifera, Demospongiae, Hadromerida) from the Canadian Northeast Pacific with remarks on the use of microtomography in sponge taxonomy
FIGURE 6. Morphometric correlations between megasters and megascleres in T. leysae sp. nov. A. Diameter of megasters vs. R/C ratio (ray length to radius of the massive spicule center), including linear fitted graphs. Choanosomal megasters (filled circles, Ch, n=85) are significantly smaller (independent t-test; p<0.001) than cortical megasters (filled triangles, Co, n=227). The same applies to R/C values, which are significantly lower for choanosomal megasters (independent t-test; p<0.001), indicating more solid megasters with shorter rays and/or relatively more solid centers. Both differences are also represented by the linear fitted graphs. B. Length of megascleres plotted vs. width. Main and auxiliary megascleres represent two significantly different size classes, in terms of both length and width (independent ttests, p<0.001).

FIGURE 3 in Description and molecular phylogeny of Tethya leysae sp. nov. (Porifera, Demospongiae, Hadromerida) from the Canadian Northeast Pacific with remarks on the use of microtomography in sponge taxonomy
FIGURE 3. Skeletal and overall anatomy of T. leysae sp. nov. (resin slice preparation of the holotype). A. Cross section through cortex (Co) and choanosome (Ch); radial megasclere bundles (rMSB) fan out slightly in the peripheral cortex region. B. – C. Details of the cortex (B) and choanosome (C). The cortex appears solid with almost no subdermal lacunae; it is densely filled with megasters, in contrast to the very low megaster density of the choanosome. Auxiliary megascleres (aMS) are present in the cortical megasclere bundle fans and separately or grouped in the choanosome. D. – G. Asters in the cortex and the choanoderm; peripheral micrasters (ma) are associated with the exopinacoderm (D); megasters (MA) dominate the cortex; the average distance between megasters is lower than one megaster diameter (D & E, see Fig. 4); A peripheral cortical layer 200 – 400 µm thick is almost completely free of megasters (D), subcortical lacunae are present near the inner cortical boundary, thus appearing partly free of megascleres (E); the choanoderm is largely free of megasters (E–F) or they show up in clouds (G), with a much lower density compared to the cortex.
FIGURE 2. A– B in Description and molecular phylogeny of Tethya leysae sp. nov. (Porifera, Demospongiae, Hadromerida) from the Canadian Northeast Pacific with remarks on the use of microtomography in sponge taxonomy
FIGURE 2. A– B. True to scale comparison between the habitus of T. leysae sp. nov. (A, paratype) and T. californiana (B; figure modified from Sarà & Corriero, 1993). C. Tethya leysae sp. nov in situ in Barkley Sound. Asterisks indicate stalkless buds. The image is a scan of a diapositive; neither the used film material nor the scanner was color-calibrated; therefore, the colors might deviate from natural colors (image courtesy of S. Leys, Edmonton).
FIGURE 4. Virtual 3D in Description and molecular phylogeny of Tethya leysae sp. nov. (Porifera, Demospongiae, Hadromerida) from the Canadian Northeast Pacific with remarks on the use of microtomography in sponge taxonomy
FIGURE 4. Virtual 3D reconstructions of the cortical skeleton of T. leysae sp. nov. (holotype) imaged using synchrotron radiation-based x-ray micro computer tomography (SR µCT). The massive megasclere bundles reach diameters of up to 500 µm; there is no free space between asters and megasclere bundles as sometimes seen in other Tethya species; patchy aster-free regions are occupied by canals (tissue not visible in spicule-optimized SR µCT, see Nickel et al. 2006a, b). A. – B. Block diagrams of cortex preparations from the holotype (A) and the paratype (B). C. Detail cropped from the paratype (coordinate system in mm). Additional 3D-renderings of the holotype as well as the paratype are available upon request.
