Algal Epiphyte Biomass from Seagrass Tissue Along the South Texas Coast (2011 - 2021)
<p>Estimates of algal epiphytic biomass are made from separate leaf samples of entire shoots. Leaf samples for epiphytic biomass must be processed within three days of collection. In the laboratory, epiphytes are separated from a known leaf area using a scalpel or razor blade. Scraped material is then collected and retained on pre-weighed glass fiber filters. The collected epiphytic biomass and scraped seagrass leaves are then dried to a constant weight at 60°C for determination of dry weight biomass. Samples were taken at six sites along the Texas coast from 2011 - 2021.</p>

Fig. 9 in Morphology and histology of dorsal spines of the xenacanthid shark Orthacanthus platypternus from the Lower Permian of Texas, USA: Palaeobiological and palaeoenvironmental implications
Fig. 9. Bivariate plots of relationship between width and height in cross sections of Orthacanthus dorsal spines. A. Orthacanthus platypternus (Lower Permian, Craddock Bone Bed, Texas, USA). B. Comparison of O. platypternus with O. meridionalis (Upper Carboniferous, Puertollano, Spain) and Orthacanthus sp. (Upper Carboniferous, Robinson, Kansas, USA). Note the linear regression (y = 0.91x + 0.15; n = 65, r2 = 0.98) calculated by Donelan and Johnson (1997) for the isolated dorsal spines of O. platypternus. The maximum and minimal values are also included here for a comparative reference; values of the rest of the specimens are not included for clarity. Grey shaded areas indicate approximate intervals of the three size clusters corresponding to juveniles and adults according the biometric analysis by Donelan and Johnson (size intervals are based on unpublished data presented in a poster at 57th Annual Meeting of the Society of Vertebrate Paleontology, Chicago, October 1997). Note the ontogenetic trajectories of several individuals of O. platypternus (HMNS-T2 and HMNS-J3), O. meridionalis (PU-XE19, 20, 74 and 76) and Orthacanthus sp. (KUVP-72324) showing stages SP1–n spine proper). Data from O. meridionalis and Orthacanthus sp. after Soler-Gijón (1999: table 1 and figs. 4–8). Vertical grey arrows point to the position in the linear regression for SMU specimens according the maximum width values at the proximal end of denticulated regions: 3.5 mm (SMU 68799), 4.5 mm (SMU 68800) and 8.4 mm (SMU 68801). Abbreviations: SP1–5, spines 1–5; SpPr, spine proper.
Fig. 8. A in Morphology and histology of dorsal spines of the xenacanthid shark Orthacanthus platypternus from the Lower Permian of Texas, USA: Palaeobiological and palaeoenvironmental implications
Fig. 8. A. Reconstruction of the dorsal spine (mainly the denticulated region) of Orthacanthus platypternus, based on specimens HMNS-T1 and HMNS-T2. B, C. Reconstructions of the dorsal spine of Orthacanthus meridionalis (modified from Soler-Gijón 1999: fig. 10); PU-XE76 (B) PU-XE19 (C). Note that distal denticles belong to the first spine (juvenile). The intersection of the first major growth line and the denticulated border of the spine indicate the proximal end of the denticulated region of the first spine; the following "spines" exhibit the distal denticles and those corresponding to each new growth stage.
