Descrição

Genus: Grammatophora Ehrenberg, C.G. (1840).
The type species (lectotype) of the genus Grammatophora is Grammatophora angulosa Ehrenberg (Guiry and Guiry 2023)

Taxonomic notes on the genera:

Phylum Bacillariophyta
Subphylum Bacillariophytina
Class Bacillariophyceae
Subclass Fragilariophycidae
Order Rhabdonematales
Family Grammatophoraceae

Found on Z. marina at Montague Harbour Marine Provincial park (MHMPP)

Taxonomic characteristics of the genus:

  1. An araphid genus, they often form zig-zag colonies attached to marine substrates
  2. In girdle view the cells appear rectangular to square
  3. In valve view the cells are elongate with rounded apices and no distinct central area
  4. The girdle bands, closet to the valves (valvocopula) display distinctive undulating septa
  5. The septa, either highly undulate or straight run from the apex of the girdle band nearest the valve (valvocopula) and terminate close to the cell centre. Towards the centre, the septa sometimes hooks back towards the valve. As the cell decreases in size the septa change shape and become less undulate, except for the hooked end which is morphologically stable (Sato et al. 2010)
  6. Apical pore fields, where there are generally small spines
  7. Pseudosepta located at the apices
  8. Areolae are fine, poroid, uniserate and transverse, linearally arranged or five poroids arranged in a cross (quincunx pattern)
  9. Chloroplasts are four per cell, filling the space in the septa
  10. Two rimoportulae located close to the apices (Round et al. 1990, Sato et al. 2010, Spaulding et al. 2021)

Methods:
Collected by brushing or scrapping leaf sections of Z. marina from MHMPP, August 3, 2020, October 16, 2020, March 7, 2021 and July 2021. Cells were cleaned with concentrated hydrogen peroxide or nitric acid at 100 C for 3-5 hours to remove organics, then rinsed multiple times in ddH20 to a neutral pH. Mounted on SEM stubs or in Naphrax on slides for light microscopy. Imaging with a Nikon TE300 and Tuscen DigiRetna16 MP camera or Nikon E800.
Live specimens were imaged with either a Nikon TE300 or Nikon E800 with either bright-field or DIC. In-situ, environmentally prepared samples were made using minimal contact of 8-10 mm leaf section, soaked in ddH2O to remove salts and dried through an EtOH series (50%-100%) and finished off with 100% Hexamethyldisilane HMDS (Hazrin-Chong and Manefield 2012). Mounted on carbon stickies onto aluminum SEM stubs and imaged with either the Hitachi s4800 or TM4000 at AMF, at University of Victoria, B.C. My thanks to Siobhan Schenk and Laura Parfrey in the Parfrey Lab at UBC for molecular data from the eelgrass and a collaboration with IMERSS. Also thanks go to Elaine Humphrey of the AMF, UVIC, imaging by Ron Read, Melanie Quenneville and Arjan van Asselt. Imaging, taxonomy and identifications by M. Webber.

Mag. 100x (1,3,5), 400x (2,4,6)
Very large pennate diatom (common in this water sample); 3 specimens were photographed with lengths 520µ, 540µ, and 575µ. Images 1 and 2 suggest a clash of Titans; the 230µ long Pinnularia (perhaps P. pulchella) is less than half the length of its rival. Images 3-6 record the 2nd & 3rd specimens (dead; frustules more exposed) of this huge pennate diatom. roman_romanov speculates these giants belong to the genus Nitzschia or Tribonella (https://www.inaturalist.org/observations/124342691).

Descrição

Asterionella formosa Hassall 1850.

Phylum: Bacillariophycophyta, Subphylum: Bacillariophytina, Class: Bacillariophceae, Order: Rhabdonematales, Family: Tabellariaceae.

Holotype species: Asterionella formosa Hassall 1850 = A. gracillima (Hantzsch) Heiberg 1863 (Plinski and Witkowski 2020, Guiry and Guiry 2023)

In girdle view, typical radiate colony of 4 to 8 cells (Smith1850) and elongate, narrow, linear. They have unequally inflated capitate ends and the valves are distinctively heteropolar. The proximal end of the valve (foot pole) is attached to other cells in the colony. Cells tapering from the middle to the apices. The foot pole is slightly larger and distinctively capitate compared to the distal valve end. A transverse rimoportula is located at both apices. Areolae are uniserate and very fine; 24-28 (Patrick and Reimer 1966, Spaulding 2012 and Plinski and Witkowski 2020), this Howe Sound specimen is 30 in 10 µm. Striae are offset from one another at the very narrow central sternum. Apical pore field present at both poles. Irregular marginal spines may, or may not, be present (Spaulding 2012). Chloroplasts are numerous small plates. Size range: 40-130 µm long x 1-3 µm width (Patrick and Reimer 1966); 30-160 µm long x 1.3-6 µm wide (Plinski and Witkowski 2020); 45-68 µm long x 1.1-4.5 µm wide (freshwater) (Spaulding 2012). Howe Sound specimen: 76.4 x 2.4 µm. Environment; freshwater (Smith1850, Patrick and Reimer 1966, Sims 1996, Guiry and Guiry 2023); marine or estuarine (Mayama et al. 2018, Plinski and Witkowski 2020).

SEM images of Asterionella formosa found with the sponge Hymedesmia sp., Anvil Island, Howe Sound. B.C. Depth 60 ft. August 19, 2011. Specimen NM 267. Imaged by Ron Read on a Hitachi s4800 SEM. SEM specimen prepared by Elaine Humphrey, Advanced Microscope Facility (AMF), University of Victoria. From specimens collected by Bruce Ott (Royal British Columbia Museum) and Neil McDaniel (Neil McDaniel Marine Consulting). Taxonomy by MW.

Scale Bar = 10 microns.

This specimen was collected from the bottom layer of a volcanic ash deposited approximately 11.8 million years ago. This specimen had secondary costae and a costae density of 3 per 10 microns. Valves are elliptical nearly circular. This specimen was identified using Schmidt's Plates and the Hustedt Collection which was collected from a deposit of approximately the same time frame in Oregon. The specimens did not correspond well to the dimensions published in Williams 1996; however, his dimensions did not match the figures published in the same paper. This form is distinguished by its diminutive size and nearly circular valves.

Mag. 400x
Freshwater, asymmetric diatom. The 3 photos in image 1 depict a small rotation around its longitudinal axis. Based on its uniquely large size (180µ L x 50µ W), apiculate and capitate apices, striae count per 10µ (7 at the valve center and 9 near the apices), this specimen (to my eyes) looks like Cymbopleura inequalis. For more information and reference photos see https://diatoms.org/species/cymbopleura_inaequalis and https://www.algaebase.org/search/species/detail/?species_id=q6409a9e46e8376c6.

Descrição

NOT N. bisulcatum, except maybe the first 3. N. bisulcatum sensu strictu has a width range of 8-9 microns. The majority of the specimens here are a similar taxon that has been erroneously lumped into the species concept of N. bisulcatum by many authors over the course of the last century.

Descrição

Found in an alpine rock pool. photos taken at 400x total magnification. Another type of colonial motile green algae. It appears to be morphologically distinct from the other taxa I documented here. I have a photo of the two taxa next to each other if anyone is interested.
