Fig. 6 in New cranial material of the earliest filter feeding flamingo Harrisonavis croizeti (Aves, Phoenicopteridae) informs the evolution of the highly specialized filter feeding apparatus
Fig. 6 Cladogram showing the relationship of Harrisonavis croizeti to other members of Mirandornithes (flamingos and grebes; Sangster, 2005). H. croizeti is placed outside of the crown group based on apomorphic data presented in this study. The relationships of the crown clade are from Torres et al. (2014). The placement of Juncitarsus (Olson and Feduccia 1980) is uncertain (indicated by a dashed line); treatment here follows Mayr (2014a). Extinct taxa denoted by dagger symbols

Fundamental niche narrows through larval stages of a filter-feeding marine invertebrate
<p>Ontogenetic niche theory predicts that resource use should change across complex life histories. To date, studies of ontogenetic shifts in food niches have mainly focused on a few systems (e.g. fish), with less attention on organisms with filter-feeding larval stages (e.g. marine invertebrates). Recent studies suggest that filter-feeding organisms can select specific particles, but our understanding of whether niche theory applies to this group is limited. We characterised the fundamental niche (i.e. feeding proficiency) by examining how niche breadth changes across the larval stages of the filter-feeding marine polychaete <em>Galeolaria</em> <em>caespitosa</em>. Using a no-choice experimental design, we measured feeding rates of trochophore, intermediate-stage and metatrochophore larvae on the prey phytoplankton species: <em>Nannochloropsis</em> <em>oculata</em>, <em>Tisochrysis</em> <em>lutea</em>, <em>Dunaliella</em> <em>tertiolecta</em> and <em>Rhodomonas</em> <em>salina</em>, that vary 10-fold in size, from the smallest to the largest. We formally estimated Levins' niche breadth index to determine the relative proportions of each species in the diet of the three larval stages and also tested how feeding rates vary with algal species and stage. We found that early stages eat all four algal species in roughly equal proportions, but niche breadth narrows during ontogeny, such that metatrochophores are feeding specialists relative to early stages. We also found that feeding rates differed across phytoplankton species—the medium-sized cells (<em>Tisochrysis</em> and <em>Dunaliella</em>) were eaten most, and the smallest species (<em>Nannochloropsis</em>) was eaten the least. Our results demonstrate that ontogenetic niche theory describes changes in fundamental niche in filter feeders—an important next step is to test whether the realized niche (i.e. preference) changes during the larval phase as well.</p>

Filter feeding, deviations from bilateral symmetry, developmental noise and heterochrony of hemichordate and cephalochordate gills
<p><span>We measured gill slit fluctuating asymmetry (FA), a measure of developmental noise, in adults of three invertebrate deuterostomes with different feeding modes: the cephalochordate <i>Branchiostoma floridae </i>(an obligate filter feeder), and the enteropneusts<i> Protoglossus graveolens</i> (a facultative filter feeder / deposit feeder) and <i>Saccoglossus bromophenolosus</i> (a deposit feeder). FA was substantially and significantly low in <i>B. floridae</i><i> </i>and <i>P. graveolens,</i> and high in <i>S. bromophenolosus</i>. Our results suggest that the gills of species that have experienced a relaxation of the filter feeding trait exhibit elevated FA. We found that the timing of development of the secondary collagenous gill bars, compared to the primary gill bars, was highly variable in <i>P. graveolens </i>but not the other two species, demonstrating an independence of gill FA from gill bar heterochrony. We also discovered the occasional ectopic expression of a second set of paired gills posterior to the first set of gills in the enteropneusts, and that these were more common in <i>S. bromophenolosus</i>. Moreover, our finding that gill slits in enteropneusts exhibit bilateral symmetry suggests that the left-sidedness of larval cephalochordate gills, and the directional asymmetry of Cambrian stylophoran echinoderm fossil gills, evolved independently from a bilaterally symmetric ancestor.</span></p>

Fig. 5 in New cranial material of the earliest filter feeding flamingo Harrisonavis croizeti (Aves, Phoenicopteridae) informs the evolution of the highly specialized filter feeding apparatus
Fig. 5 Digital reconstruction of Harrisonavis croizeti comprising newly reported material compared with the cast of the lectotype of H. croizeti. Reconstruction in left (a) and right (b) views. Cast of the lectotype skull of H. croizeti (NMNH Av 6544) (c). In addition to other characters (see text), the new upper bill is less curved compared to the previously reported and presumably adult bill, suggesting a sub-adult condition for NMB MA 9594. In the reconstruction of H. croizeti (a, b), the component fossils (indicated by specimen number and by color) have not been modified from their original scales and were fitted by eye in three- dimensional space. Some overlap occurs where the specimens pre- serve the same region of the skull. Scale bars 1 cm
