(2012) which was based on two nuclear (erdnrb1, phpt1) and one mitochondrial (ND2) marker and the GTR+G model of molecular evolution. See for full details of species acronyms. Images shown are, from left to right: Astatotilapia burtoni (asbur), Simochromis babaulti (simbab), Tropheus moori (tromoo), Cyathopharynx furcifer (cyafur), Xenotilapia spiloptera (xenspi), Perissodus microlepis (permic), Gnathochromis permaxillaris (gnaper), Altolamprologus calvus (altcal), Neolamprologus sexfasciatus (neosex), Neolamprologus pulcher (neopul) and Bathybates graueri (batgra).

Differences in milt diffusion rates and glycosylation states of SPP120 among the fertilization types of cichlids from Lake Tanganyika. a Milt diffusion was evaluated in seven species (see also Additional file : Figure S4) and compared (Phylogenetic generalized least squares P < 0.005; see also Additional file : Table S3). Oral fertilization species: Or. mossambicus (N = 3), Petrochromis fasciolatus (N = 4), and Ophthalmotilapia ventralis (N = 4); Stocked-spermatozoa fertilization species: Cyathopharynx furcifer (N = 3) and Op. nasuta (N = 3); and substrate fertilization species: Variabilichromis moorii (N = 3), and Lepidiolamprologus elongatus (N = 3). b Glycosylation states of SPP120 in these seven species are also shown. c Transitions among glycosylation states were calculated in BayesTraits version 2.0 according to maximum likelihood estimations. Arrows indicate transition rates (O₀₁, Q₁₀), which are an indicator of how likely a particular transition is to have occurred. Q₀₁ indicates rates from non-glycosylated SPP120 to glycosylated one, Q₁₀ is from glycosylated SPP120 to non-glycosylated one. Histograms of each transition rate are also shown
