In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoo/ogy Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world cf science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.

Here we report the sequencing and de novo assembly of the genome of the tiger tail seahorse, Hippocampus comes. Comparative genomic analysis identifies higher protein and nucleotide evolutionary rates in H. comes compared with other teleost fish genomes. We identified an astacin metalloprotease gene family that has undergone expansion and is highly expressed in the male brood pouch. We also find that the H. comes genome lacks enamel matrix protein-coding proline/glutamine-rich secretory calcium-binding phosphoprotein genes, which might have led to the loss of mineralized teeth. tbx4, a regulator of hindlimb development, is also not found in H. comes genome. Knockout of tbx4 in zebrafish showed a ‘pelvic fin-loss’ phenotype similar to that of seahorses. Members of the teleost family Syngnathidae (seahorses, pipefishes de novo.

  • The Genome of the Gulf Pipefish Enables Understanding of Evolutionary Innovations C

Bassham1†, J. Catchen1,2†, A. Amores3, A. M. Fuiten1, R. S. Brown1,4, A. G. Jones5 and W. A. Cresko1* Abstract Background: Evolutionary origins of derived morphologies ultimately stem from changes in protein structure, gene regulation, and gene content. A well-assembled, annotated reference genome is a central resource for pursuing these molecular phenomena underlying phenotypic evolution. We explored the genome of the Gulf pipefish (Syngnathus scovelli), which belongs to family Syngnathidae (pipefishes, seahorses, and seadragons). These fishes have dramatically derived bodies and a remarkable novelty among vertebrates, the male brood pouch. Results: We produce a reference genome, condensed into chromosomes, for the Gulf pipefish. Gene losses and other changes have occurred in pipefish hox and dlx clusters and in the tbx and pitx gene families, candidate mechanisms for the evolution of syngnathid traits, including an elongated axis and the loss of ribs, pelvic fins, and teeth. We measure gene expression changes in pregnant versus non-pregnant brood pouch tissue and characterize the genomic organization of duplicated metalloprotease genes (patristacins) recruited into the function of this novel structure. Phylogenetic inference using ultraconserved sequences provides an alternative hypothesis for the relationship between orders Syngnathiformes and Scombriformes. Comparisons of chromosome structure among percomorphs show that chromosome number in a pipefish ancestor became reduced via chromosomal fusions. Conclusions: The collected findings from this first syngnathid reference genome open a window into the genomic underpinnings of highly derived morphologies, demonstrating that de novo production of high quality and useful reference genomes is within reach of even small research groups.

Abstract A checklist of shallow (to 60 m depth) reef fishes is provided for the Bird’s Head Peninsula region of West Papua, Indonesia. The area, which occupies the extreme western end of New Guinea, contains the world’s most diverse assemblage of coral reef fishes. The current checklist, which includes both historical records and recent survey results, includes 1,511 species in 451 genera and 111 families. Respective species totals for the three main coral reef areas – Raja Ampat Islands, Fakfak-Kaimana coast, and Cenderawasih Bay – are 1320, 995, and 877. In addition to its extraordinary species diversity, the region exhibits a remarkable level of endemism considering its relatively small area. A total of 26 species in 14 families are currently considered to be confined to the region. Introduction and finally a complex geologic past highlighted The region consisting of eastern Indonesia, East by shifting island arcs, oceanic plate collisions, Timor, Sabah, Philippines, Papua New Guinea, and widely fluctuating sea levels (Polhemus and the Solomon Islands is the global centre of 2007). reef fish diversity (Allen 2008).

Varella* and Mark H. Sabaj Pérez** Apistogramma kullanderi, new species, is described from the upper rio Curuá (Iriri-Xingu drainage) on Serra do Cachimbo, Pará, Brazil, and diagnosed by its maximum size of 79.7 mm SL (vs. 65.3 mm SL among wild-caught congeners); mature females having the unique combination of intense dark pigmentation continuous along base of dorsal fin and on ventral surfaces from gular region to anal-fin base; and mature males having a coarse, ir- regular pattern of dark spots and vermiculations on cheek and opercular series, and sides with 10-12 dark stripes, each stripe occupying proximal limits of adjacent scale rows and separated by paler region central to each scale. Apistogramma kullanderi is tentatively allocated to the A. regani lineage, although some characteristics (e. g., large body size) are more consistent with members the A. steindachneri lineage. Apistogramma kullanderi is endemic to an upland watershed isolated by large waterfalls and depauperate of cichlid diversity. Under those conditions, we speculate that ecological opportunities, reduced competition and sexual selection contributed to the evolution of large body size in A. kullanderi.

Ledeganckstraat 35, B-9000 Gent, Belgium and ‡UGCT, Department of Physics and Astronomy, Proeftuinstraat 86, B-9000 Gent, Belgium A thorough morphological description of the feeding apparatus in Hippocampus reidi, a long-snouted seahorse, and Dunckerocampus dactyliophorus, an extremely long-snouted pipefish, revealed spe- cialized features that might be associated with the fast and powerful suction feeding, like the two ligamentous connections between the lower jaw and the hyoid, the saddle joint of the latter with the suspensorium and the vertebro-pectoral fusion that articulates on three points with the cranium. Despite the conserved morphology of the feeding apparatus, it was found that in H. reidi the orien- tation of the occipital joint is ventrocaudal, the sternohyoideus and epaxial muscles are more bulky and both have a short tendon. In D. dactyliophorus, on the other hand, the protractor hyoidei muscle is enclosed by the mandibulo-hyoid ligament, the sternohyoideus and epaxial tendons are long and a sesamoid bone is present in the latter. These features were compared to other syngnathid species with different snout lengths to evaluate the implications of snout elongation on the musculoskeletal structure of the cranium. The arched path of the adductor mandibulae and the greater rigidity of the lower jaw might be related to elongation of the snout, as it yields an increased mechanical advantage of the lower jaw system and a reduced torque between the elements of the lower jaw during protractor hyoidei muscle contraction, respectively.
