Fig. 1 in Multiloci analyses suggest synonymy among Rhomboplites, Ocyurus and Lutjanus and reveal the phylogenetic position of Lutjanus alexandrei (Lutjanidae: Perciformes)
Fig. 1. Phylogenetic relationships in Lutjaninae species from the Western Atlantic estimated by Bayesian (BI), maximum likelihood (ML) and a Species Tre analyses inferences based on a data matrix (4.4 kb) comprising mitochondrial (16S rRNA, COI, cyt b, and ND-4) and nuclear (Rhodopsin, TMO4C4 and RAG-1) markers. The BI topology is presented with the posterior probability (BI and Species Tree) and bootstrap (ML) values. The letters in the nodes refer to the clades discussed in the text.

Figure 1 in Oocyte distribution, ovarian organization, and spawning pattern in Lutjanus griseus
Figure 1. – Phase-specific variation of oocyte size frequency in ovaries from female Lutjanus griseus in the early developing subphase; spawning capable phase; actively spawning subphase; and past-spawner subphase. Oocytes undergoing germinal vesicle breakdown (GVBD) and hydrated (H) were observed during the actively spawning subphase, but their diameter could not be determined since nucleus was not visible. PG = primary growth oocyte (mean diameter = 47.1 ± 15.1 μm, n = 46730); CA = cortical alveolar oocyte (128.3 ± 29.5 μm, n = 3148); Vtg1 = primary vitellogenic oocyte (190.3 ± 28 μm, n = 709); Vtg2 = secondary vitellogenic oocyte (258.32 ± 29 μm, n = 631) and Vtg3 = tertiary vitellogenic oocyte (298.58 ± 28.2 μm, n = 935); OM (GVM) = oocyte undergoing germinal vesicle migration (274.47 ± 21.2 μm, n = 6). Postovulatory follicles were present in ovaries of past-spawner females.

SSU rDNA-based maximum likelihood (GTR + Γ model) tree of 26 myxosporean sequences showing the phylogenetic position of Sphaerospora motemarini n. sp. amongst all other polysporoplasmid Sphaerospora spp. sequenced to date (red) and within the Sphaerospora sensu stricto clade (yellow). Members of marine (blue) and freshwater (green) myxosporean lineages were used as outgroups. Maximum likelihood bootstraps/maximum parsimony bootstraps/Bayesian posterior probabilities shown at nodes. Dashes indicate bootstrap values <50 or not present in the maximum parsimony or Bayesian tree.
