Fig. 11 in Three-dimensional micro- and nanostructural characteristics of the scleractinian coral skeleton: A biocalcification proxy
Fig. 11. Platygyra daedalea (Ellis and Solander, 1786); ZPALH.23/8 (originally NMNH A.G. Humes collection. Acc. number 274378). Recent, 25 m, north of Ankazo−beravina, near Nosy Be, Madagaskar, August 24, 1967. A. Transverse polished section of septum in TLM; note brownish "calcification centers" (dRAF), regular growth increments of fibers (e.g., in encircled area), and dark brown regions (red arrows) of filaments of endolithic organisms (most likely algae, fungi). B. The same septal fragment as A, stained with acridine orange in MFM view; dRAF exhibit very light, green−yellow fluorescence; higher magnifications (C) show delicate greenish bands matching organic components trapped between successive growth increments of fibers (white arrows). D. Transverse polished section of septum in TLM; dRAF in lower right corner; regular growth increments of fibers (TD) are emphasized by levels of brownish bands. E. SEM micrograph of transverse polished and etched section of septum; fibers adjacent to row of dRAF ("calcification centers") taper regularly at ca. 3 µm matching brownish bands in D.
Fig. 7 in Three-dimensional micro- and nanostructural characteristics of the scleractinian coral skeleton: A biocalcification proxy
Fig. 7. Desmophyllum dianthus (Esper, 1794). ZPALH.23/3. Recent, southern Indian Ocean (NE St. Paul Island), MD50 cruise, Stat. 32/CP 145, 38°40.66'S, 77°35.47'E, 825–1020 m. A, B. Polished and etched septum sectioned transversely (A) and longitudinally in RAF plane (B). dRAF form chain of dCRA ("centers of calcification") (A), which sectioned longitudinally exhibit alternating etching relief (B). dCRA (A) are composed of apparently non−crystalline, "blurry" material. C–E. Transverse polished section of septum in TLM (C, D) and MFM (E) micrographs. In TLM (C, D) organic components differentiate into dark−brown zone of wall and septal dRAF and light−brown, banded zone enclosing dRAF; in MFM (E) they exhibit lighter, green−yellow, and darker, greenish fluorescence, respectively. Contact zone between bundles of fibers (also with apparent fractures) contain organic matter that forms a fluorescent network (E); examples highlighted with red arrows. F, G. Septum longitudinally sectioned in RAF plane in TLM (F) and MFM (G). Minute growth increments (less than 5 µm) appear as "denticulations" on fluorescent bars (G). Growth direction within septum indicated by black arrow.
Fig. 6. Flabellumchunii Marenzeller, 1904. ZPALH.23 in Three-dimensional micro- and nanostructural characteristics of the scleractinian coral skeleton: A biocalcification proxy
Fig. 6. Flabellumchunii Marenzeller, 1904. ZPALH.23/2/4. Locality data as in Fig. 5. A–C. Complementary regions of longitudinally sectioned and polished septum (RAF plane): TLM (A), Back−Scattered Electron mode (BSE) (B), and pseudocolor carbon mapping images acquired on the electron microprobe by wavelength−dispersive techniques (C); black/dark blue equals lower concentration (<150 counts per second) whereas yellow−white equals higher concentrations (>150 c/s). Brownish structures exposed at section surface (A), appear darker in BSE mode (B) as it enhances atomic number contrast; elements with lower atomic numbers appear darker, those with higher atomic numbers appear lighter. BSE darker regions (arrows) match exactly to carbon−enriched regions in WDS x−ray mapping image (C, arrows). D–F. TL M (D, E) and MFM (F) micrographs of longitudinally sectioned septum. Organic and mineral phase of dRAF regularly alternate (grayscale enlargement in E); brownish organic components (D) exposed and stained with acridine orangedye, fluoresce (F) with bright−green light. Growth direction within septum indicated by black arrow.
Checklist of scleractinian coral species in Mangrove Bay, El Qoseir, Egypt
<p>This dataset contains observational data on scleractinian coral species from two reef sites at Mangrove Bay, El Qoseir, Egypt, serving as a baseline for future research and conservation. Collected between October 19th and 25th, 2023, the data includes coordinates, transect details, depth measurements, exposure levels, and life form categories. Surveys were conducted at two sites with different exposure levels (a sheltered reef site and a current-exposed reef site) using the Line Intercept Transect (LIT) method. Each site was surveyed with three 20 m LIT's within three depth zones: reef edge (0–1 m), shallow reef slope (3.7–4.75 m), and deeper reef slope (7.2–9.5 m), totaling eighteen transects. Coordinates were recorded via GPS.</p> <p>Life forms were categorized using codes adapted from English et al.
