Fig. 4 in Redescription of Dexiotricha colpidiopsis (Kahl, 1926) Jankowski, 1964 (Ciliophora, Oligohymenophorea) from a Hot Spring in Iceland with Identification Key for Dexiotricha species

Fig. 4. Phylogenetic tree inferred by Maximum-likelihood (ML) analyses of the small SSU rRNA gene sequences. The new sequence is highlighted in bold. Numbers at the nodes are the bootstrap values of the ML and BI analyses, respectively. The mark "-" indicates discrepancies in the topologies of the ML and BI trees; thus, only the values of ML are shown in these cases. The scale bar corresponds to 5 substitutions per 100 nucleotide positions.

Figure 1 in Quantitative assessment of species identification in aerial transect surveys for ice-associated seals

Figure 1. The characteristic bands on the coats of ribbon seals are not necessarily clearly visible in an aerial image. The images on the top right and bottom right were taken with a Canon 1Ds Mark III fitted with a Zeiss 100 mm lens from 300 m during a 2012 line transect survey in the Bering Sea. In the top right image, an observer would likely rely on the clearly visible bands to conclude that the seal is certainly a ribbon seal. In the bottom right image, an observer would likely rely on a combination of body shape, head size, flipper size and shape, and what could be one or more bands to conclude that the seal is probably a ribbon seal.

Figure 3 in Quantitative assessment of species identification in aerial transect surveys for ice-associated seals

Figure 3. Observed species and age class identification probabilities for four species of iceassociated seals in the Bering Sea. True species and age classes include spotted seal pup (SDP), spotted seal nonpup (SDN), ribbon seal pup (RNP), ribbon seal nonpup (RNN), bearded seal pup (BDP), bearded seal nonpup (BDN), ringed seal pup (RDP), and ringed seal nonpup (RDN). Observed species classifications include spotted seal (red), ribbon seal (green), bearded seal (yellow), ringed seal (blue), and unknown seal (white). Observed age classes include pup, nonpup, and unknown. Solid colors with no hashing indicate unknown age classification. Top panel (a) includes results from an analysis with no observer effects on model parameters. Bottom four panels (b) correspond to four different observers from an analysis including observer effects.

Figure 2. A in Quantitative assessment of species identification in aerial transect surveys for ice-associated seals

Figure 2. A red face, which is one of the characteristics associated mostly with bearded seals, is not always present, nor is it necessarily visible in an aerial image. The image on the right was taken with a Canon 1Ds Mark III fitted with a Zeiss 100 mm lens from 300 m during a 2012 line transect survey in the Bering Sea. In this image, an observer would likely rely on the combination of body shape, head size, front-flipper size and shape, and position on the floe to conclude that the seal is probably or certainly a bearded seal.
