Figure 5 in Vertical distribution of brown and red macroalgae along the central Western Antarctic Peninsula

Figure 4 in Vertical distribution of brown and red macroalgae along the central Western Antarctic Peninsula
Figure 4: Vertical distribution of seven red macroalgal species by the number of transects in which they were present in the diver byhand collections. Sites are ordered by National Ice Center average sea ice concentrations from 2014 to 2019. No fleshy red macroalgae were present at site K, and none of the species included in this report were present at site N. Only two transects were sampled at site I, so the abscissa only extends to two for that site. Single blue asterisks indicate one less transect collection at that depth at that site; "(present)" indicates that the species was found in general collections at the site but was not present in the transect collections.
Figure 3 in Vertical distribution of brown and red macroalgae along the central Western Antarctic Peninsula
Figure 3: Vertical distribution of Desmarestia menziesii and Desmarestia anceps combined and of Himantothallus grandifolius at horizontal depth intervals from video transect analyses. Means + standard error of mean. Sample size was two at sites H, I, and K and three at all other sites. Sites are ordered by National Ice Center average sea ice concentrations from 2014 to 2019. No fleshy macroalgae were present at site K so it is not included. "(present)" indicates that the species was found in general collections at the site but was not present under a random dot in the video analyses.

Figure 1 in Vertical distribution of brown and red macroalgae along the central Western Antarctic Peninsula
Figure 1: Study sites along the central Western Antarctic Peninsula. Inset shows the entire northern and central portions of the Antarctic Peninsula. The 14 research sites, designated north to south as A through N, were surveyed between April 23 and May 18, 2019. Their locations spanned the range of annual sea ice coverage (color scale bar). Modified from Amsler et al. (2023).

Figure 3 in Phylogeographic patterns in attached and free-living marine macroalga Fucus vesiculosus (Fucaceae, Phaeophyceae) in the Baltic Sea
Figure 3: Distribution of concatenated-barcode mtDNA intergenic spacer (IGS) and 23S haplotypes found within the Baltic sea Fucus vesiculosus population. Circle size is proportional to sample size (n) and form is indicated as A (attached) or F (free-living). Site abbreviations: As, AskÖ; HS, Hiddensee; OL, Olkiluoto; SA, Saaremaa; SE, Seili; TZ, Tvärminne. Scale: 200 km.
Figure 2 in Phylogeographic patterns in attached and free-living marine macroalga Fucus vesiculosus (Fucaceae, Phaeophyceae) in the Baltic Sea
Figure 2: Haplotype network analysis of Fucus vesiculosus using (A) concatenated-barcode mtDNA intergenic spacer (IGS) and 23S, and (B) mtDNA polymorphic region-intergenic spacer (pr-IGS). Circle size is proportional to the haplotype frequency. A branch represents a genetic distance and hash marks represent a single mutation. Branches drawn in broken grey lines represent genetic distances between non-linked haplotypes [not shown in (B)]. All undrawn branches between non-linked haplotypes within B equal <2 mutations. Segment colouration indicates the geographic origin of each haplotype whilst ellipses represent the coverage of each geographic region within the network. Site abbreviations: As, AskÖ; HS, Hiddensee; OL, Olkiluoto; SA, Saaremaa; SE, Seili; TZ, Tvärminne.

Figure 4 in Agrobacterium-mediated gene delivery and transient expression in the red macroalga Chondrus crispus
Figure 4: Effect of cultivation medium, wounding method and acetosyringone on Agrobacterium transformation efficiency. The transformation efficiencies of Chondrus thalli segments co-cultivated with pCAMBIA 1301-transformed Agrobacterium in seawater and Induction Medium (IM) were compared. Using seawater as co-cultivation medium, the wound-related treatments, namely biolistics wounding, wounding using pin-pricks and no wounding, were compared. The effect of acetosyringone (100 µM) was also studied. Data are expressed as means ± SE (n = 4). The Mann-Whitney non-parametric test was conducted to compare between two groups.

Thalli co-cultivated for 48 h in induction medium were fixed and viewed under a scanning electron microscope: (A) control thallus incubated without bacteria showing a clean bacterium-free surface; (B) close up view of rod-shaped bacteria attached to thallus surface at wound site; (C) bacterial film at wound sites on thallus surface.
