Fig. 1. Two species indicative of the morphological and behavioural variation found among the sand-dwelling fish assemblage in an Amazonian streamlet: a, the diurnally active Characidium cf. pteroides in its characteristic sit-and-wait posture while foraging for bottom-dwelling prey; b, the nocturnally active Gymnorhamphichthys rondoni in its typical headdown posture while actively searching for interstitial prey.

Figure 2 in Phylogenetic structure of the Sphaeriinae, a global clade of freshwater bivalve molluscs, inferred from nuclear (ITS-1) and mitochondrial (16S) ribosomal gene sequences

Figure 2. Strict consensus of the 1040 equally most parsimonious trees (L = 445; CI = 0.724; RI = 0.886) obtained from the phylogenetic analysis of sphaeriid nuclear ITS1 rDNA sequences. The inferred evolutionary gain and loss of a ~160 nt fragment are indicated. Two Eupera species, E. cubensis and E. platensis, were designated as outgroups and inferred sequence gaps were considered as missing data. Numbers above the branches represent bootstrap values and numbers below indicate decay index values.

Figure 3 in Phylogenetic structure of the Sphaeriinae, a global clade of freshwater bivalve molluscs, inferred from nuclear (ITS-1) and mitochondrial (16S) ribosomal gene sequences

Figure 3. The single most-parsimonious tree (L = 951; CI = 0.568; RI = 0.793) obtained from the maximum parsimony analysis of combined (16S + ITS1) sequence dataset. Maximum likelihood analysis produced a largely congruent topology (HKY model; Ln likelihood = - 7034.61154) with the only difference being Pisidium dubium sister to Sphaerium/Musculium clade. Taxonomic names are arranged according to suggested sphaeriinid taxonomy in the present study and five major monophyletic lineages are indicated. Two Eupera species, E. cubensis and E. platensis, were designated as outgroups. MP bootstrap values are shown to the left of the slash and decay index values to the right above the branches. Numbers below the branches indicate ML bootstrap values.

Figure 1 in Phylogenetic structure of the Sphaeriinae, a global clade of freshwater bivalve molluscs, inferred from nuclear (ITS-1) and mitochondrial (16S) ribosomal gene sequences

Figure 1. Strict consensus of the four equally most parsimonious trees (L = 526; CI = 0.447; RI = 0.743) obtained from the phylogenetic analysis of sphaeriid mitochondrial 16S rDNA sequences. Two Eupera species, E. cubensis and E. platensis, were designated as outgroups and inferred sequence gaps were considered as missing data. Numbers above the branches represent bootstrap values and numbers below indicate decay index values.
