Figure 7 in Congruence and conflict: case studies of morphotaxonomy versus rDNA gene tree phylogeny among articulate brachiopods (Brachiopoda: Rhynchonelliformea), with description of a new genus
Figure 7. Ebiscothyris bellonensis gen. et sp. nov., cruise EBISCO, Coral Sea, South-West Pacific: A–H, ventral, dorsal, lateral, and anterior views of complete specimens, CP 2616, 786–836 m depth; A–D, paratype, IB-2013-2; E–H, holotype, IB-2013-1. I, dorsal view of complete specimen, with very long, thin pedicle, paratype, CP 2616, 786–836 m depth, IB- 2013-3. Scale bars: 5 mm.
Figure 6 in Congruence and conflict: case studies of morphotaxonomy versus rDNA gene tree phylogeny among articulate brachiopods (Brachiopoda: Rhynchonelliformea), with description of a new genus
Figure 6. rDNA tree of taxa with modified long loops. Best maximum-likelihood tree (GTR + invariant + gamma model) from RAxML with thorough bootstrap support (%), based on 2694 nucleotides of aligned sequences from SSU and LSU nuclear-encoded genes of 15 in-group and three rhynchonellide out-group taxa. Potentially misaligned and gapped sites (5%) were pruned by GBlocks. Several backbone nodes received very low bootstrap support and the tree has been redrawn by hand to remove them, leaving no effective resolution of relationships between the in-group superfamilies represented in this alignment. The sequence for Argyrotheca (JH97) was used with the permission of Dr J. Hoffman.
Figure 2. Case 2 in Congruence and conflict: case studies of morphotaxonomy versus rDNA gene tree phylogeny among articulate brachiopods (Brachiopoda: Rhynchonelliformea), with description of a new genus
Figure 2. Case 2: Cancellothyridoid gene tree. Best maximum-likelihood tree (GTR + invariant + gamma model) from RAxML with thorough bootstrap support (%), based on 2810 nucleotides of aligned sequences from up to four genes (12S and 16S mitochondrial, and SSU and LSU nuclear) from 30 in-group and three rhynchonellide out-group taxa. Gblocks was used to prune potentially misaligned and gap sites (18% were discarded). In-group backbone nodes with no bootstrap support value attached are considered to be unsupported (may be collapsed; boostrap <50%). Four taxa, marked (LSU), are represented by LSU sequence data alone, and in each case this sequence clusters with the cognate multiple sequences, indicating that the LSU fragment alone can accurately place the taxon.
Figure 5 in Congruence and conflict: case studies of morphotaxonomy versus rDNA gene tree phylogeny among articulate brachiopods (Brachiopoda: Rhynchonelliformea), with description of a new genus
Figure 5. Laqueoidea rDNA tree. Best maximum-likelihood tree (GTR + invariant + gamma model) from RAxML with thorough bootstrap support (%), based on 2882 nucleotides of aligned sequences from SSU and LSU nuclear-encoded genes of seven laqueoid in-group and six terebratulide out-group taxa. The small number of potentially misaligned and gap sites were not removed. The failure of the two Kingenoids to form a clade may be caused by limited sequence data rather than by misclassification.
Figure 9 in Congruence and conflict: case studies of morphotaxonomy versus rDNA gene tree phylogeny among articulate brachiopods (Brachiopoda: Rhynchonelliformea), with description of a new genus
Figure 9. Ebiscothyris bellonensis gen. et sp. nov., cruise EBISCO, Coral Sea, South-West Pacific, SEM micrographs; A, B, ventral valve, station CP 2556, 741–791 m depth, IB-2013-7; A, transverse section of the entire shell showing the primary layer (pri) underlain by the fibrous secondary layer (sec), passing into the prismatic tertiary layer (ter); B, section of the shell showing primary (pri), secondary (sec), and tertiary (ter) layers; a puncta with a radiating brush is also visible; C, D, dorsal valve, CP 2557, 800–923 m depth, IB-2013-5; C, latero-oblique view of internal surface, showing the incurved valve margin built of densely arranged sheets of secondary fibres (left) and prisms of tertiary layer (right); D, internal surface showing discrete units of prisms and very small punctae (arrows). E, F, Kanakythyris pachyrhynchos Laurin, 1997, cruise NORFOLK 2, Norfolk Ridge, station DW 2136, 402–410 m depth; E, transverse section of the entire shell; F, internal surface with discrete units of prisms. Scale bars: A, C, D, E, F, 50 μm, B, 20 μm.
Figure 4. Laqueoidea cox1 in Congruence and conflict: case studies of morphotaxonomy versus rDNA gene tree phylogeny among articulate brachiopods (Brachiopoda: Rhynchonelliformea), with description of a new genus
Figure 4. Laqueoidea cox1 tree. Best maximum-likelihood tree (GTR + invariant + gamma model) from RAxML with thorough bootstrap support (%), based on 1218 nucleotides of aligned sequences of the cox1 mitochondrial gene from 14 laqueoid in-group and six terebratulide out-group taxa. The sequences were aligned with no gaps. Nodes with no bootstrap support value attached are considered to be unsupported (bootstrap <50%) and may be collapsed.
Figure 3. Case 3 in Congruence and conflict: case studies of morphotaxonomy versus rDNA gene tree phylogeny among articulate brachiopods (Brachiopoda: Rhynchonelliformea), with description of a new genus
Figure 3. Case 3: Dyscolioid and Terebratuloid gene tree. Best maximum-likelihood tree (GTR + invariant + gamma model) from RAxML with thorough bootstrap support (%), based on 3427 nucleotides of aligned sequences from up to four genes (12S and 16S mitochondrial, and SSU and LSU nuclear) from 19 in-group and three rhynchonellide out-group taxa. Pruned of potentially misaligned and gap sites by hand (7% discarded). In-group backbone nodes with no bootstrap support value attached are considered to be unsupported (may be collapsed; boostrap <50%). Nine taxa, marked (LSU), are represented by LSU sequence data alone, and in each case this sequence clusters with the cognate multiple sequences, indicating that the LSU fragment alone can accurately place the taxon. These results validate the placement of Ebiscothyris, Dallithyris, and Dyscolia, each of which is represented by LSU alone.
