UNIVERSITY OF CALIFORNIA Los Angeles Evolution of the boxfish carapace: functional consequences of shape A thesis submitted in partial satisfaction of the requirements for the degree of Master of Science in Biology by Tina Ashley Marcroft 2015 ABSTRACT OF THE THESIS Evolution of the boxfish carapace: functional consequences of shape by Tina Ashley Marcroft Master of Science in Biology University of California, Los Angeles, 2015 Professor Michael Edward Alfaro, Chair Boxfishes are a group of heavily armored Tetraodontiform fishes that are highly variable in shape. Disparification of shape could be driven by a simple performance trade-off between its two hypothesized primary functions: protection from predation and maneuverability. Alternatively, disparification could be driven by many-to-one mapping of shape to performance, where a relaxation in morphological constraint where many of morphologies have the same performance. We tested this by isolating the major features of the boxfish carapace shape and tested for their correlation to performance, as well as for a negative correlation between performances. We found that some features were correlated but very weakly, and that the two performances did trade-off but also weakly. This weak correlation primarily suggests that many- to-one mapping of shape to performance is driving disparification, which was unobserved in continuous 3D shape systems until this study. ii The thesis of Tina Ashley Marcroft is approved.

ACTA PALAEONT OLOGICA POLONICA Vol. VII 1 9 6 2 N os. 1-2 L. BEVERLY TARLO THE CLASSIFICATION AND EVOLUTION OF THE HETEROSTRACI Abstract. - An outline classification is given of the Hetero straci, with diagnoses . of th e following orders and suborders: Astraspidiformes, Eriptychiiformes, Cya thaspidiformes (Cyathaspidida, Poraspidida, Ctenaspidida), Psammosteiformes (Tes seraspidida, Psarnmosteida) , Traquairaspidiformes, Pteraspidiformes (Pte ras pidida, Doryaspidida), Cardipeltiformes and Amphiaspidiformes (Amphiaspidida, Hiber naspidida, Eglonaspidida). It is show n that the various orders fall into four m ain evolutionary lineages ~ cyathaspid, psammosteid, pteraspid and amphiaspid, and these are traced from primitive te ssellated forms. A tentative phylogeny is pro posed and alternatives are discussed. INTRODUCTION Since 1858, when Huxley demonstrated that in the histological struc ture of their dermal bone Cephalaspis and Pteraspis were quite different from one another, it has been recognized that there were two distinct groups of ostracoderms for which Lankester (1868-70) proposed the names Osteostraci and Heterostraci respectively. Although these groups are generally considered to be related to on e another, Lankester belie ved that "the Heterostraci are at present associated with the Osteostraci because they are found in the same beds, because they have, like Cepha laspis, a large head shield, and because there is nothing else with which to associate them". In 1889, Cop e united these two groups in the Ostracodermi which, together with the modern cyclostomes, he placed in the Class Agnatha, and although this proposal was at first opposed by Traquair (1899) and Woodward (1891b), subsequent work has shown that it was correct as both the Osteostraci and the Heterostraci were agnathous. -

06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago). -

Devonian Jawless Vertebrates
FULL COMMUNICATIONS PALAEONTOLOGY Phylogenetic relationships of psammosteid heterostracans (Pteraspidiformes), Devonian jawless vertebrates Vadim Glinskiy PALAEONTOLOGY Institute of Earth Sciences, Saint Petersburg State University, Universitetskaya nab., 7–9, Saint Petersburg, 199034, Russian Federation Address correspondence and requests for materials to Vadim Glinskiy, [email protected] Abstract Psammosteid heterostracans are a group (suborder Psammosteoidei) of Devo- nian-age jawless vertebrates, which is included in the order Pteraspidiformes. The whole group of psammosteids is represented by numerous species (more than 40); their phylogenetic relationships are still poorly known and deserve further study. Classical researchers of the psammosteids, such as D. Obruchev, E. Mark-Kurik and L. Halstead Tarlo, had different views on the phylogeny of the group (e.g. origins and evolution of Psammosteus). To check the modern hy- potheses of psammosteid origins from various Pteraspidiformes and to clarify psammosteid interrelationships, the most complete phylogeny of this group (38 ingroup taxa + juvenile Drepanapsis) is presented here. Different methods of data analysis were used to explore the psammosteid data set, including equally weighted characters versus implied weighting. According to the results of the phylogenetic analysis, the monophyletic status of the group and their early development from the Pteraspidiformes are supported. The diagnoses and interrelationships of many taxa are clarified. Two new genera are proposed (Vladimirolepis -
