  • Consistency in a marine algal-grazer interaction over multiple scales

    Consistency in a marine algal‐grazer interaction over multiple scales

    Two grazer-exclusion areas characteristic of the first iteration of the disturbance experiment. The dominant plant within each square is the fleshy red alga Halosaccion glandiforme. The background is composed primarily of Corallina vancouveriensis with mussels (Mytilus californianus) at the seaward edge. The area between these squares was also scraped, but in the presence of benthic grazers has converged to the background state. Scale bar: 30 cm. Photo: 13 June 1980.

    High diversity of Pseudo‐nitzschia along the northern coast of Sarawak (Malaysian Borneo), with descriptions of P. bipertita sp. nov. and P. limii sp. nov. (Bacillariophyceae)

    Pseudo-nitzschia limii sp. nov. (A) Girdle view: note lanceolate valve and cell with 1/6 overlap. (B, C) Linear in valve view. (D) Close-up of pointed apex. (E) Central part of valve showing central interspace (arrowhead). (F) Striation showing one row of poroids and wide proximal (PM) and distal mantles (DM). (G) Close-up of poroids. Inset: poroid hymen divided into four sectors. (H–J) Details of valvocopula, second and third bands. Scale bars: 50 μm (A, B); 10 μm (C); 2 μm (D, E); 0.5 μm (F, H); 0.2 μm (G, I, J).

  • Chlorophyll f distribution and dynamics in cyanobacterial beachrock biofilms

    Chlorophyll f distribution and dynamics in cyanobacterial beachrock biofilms

    Hyperspectral imaging of brown-pigmented beachrock. (A) Combined RGB image from the hyperspectral image stack, showing “true” colors of sand grains and the beachrock biofilm community in a cross-section of the top layer. (B) A colony of unicellular Chl f-containing Chroococcidiopsis-like cyanobacteria, highlighted by the arrow in A. (C) False-color coded hyperspectral image of the same image stack as in A, where green quantifies Chl a (675–680 nm) absorption, and red quantifies Chl f (718–722 nm) absorption. (D) Spectral reflectance spectra showing distinct spectral signatures of Chl f and Chl a in the red and green-colored zones in C, respectively.
