Coping with Life on Land: Physiological, Biochemical, and Structural Mechanisms to Enhance Function in Amphibious Fishes
Coping with Life on Land: Physiological, Biochemical, and Structural Mechanisms to Enhance Function in Amphibious Fishes by Andy Joseph Turko A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Andy Joseph Turko, October 2018 ABSTRACT COPING WITH LIFE ON LAND: PHYSIOLOGICAL, BIOCHEMICAL, AND STRUCTURAL MECHANISMS TO ENHANCE FUNCTION IN AMPHIBIOUS FISHES Andy Joseph Turko Advisor: University of Guelph, 2018 Dr. Patricia A. Wright The invasion of land by fishes was one of the most dramatic transitions in the evolutionary history of vertebrates. In this thesis, I investigated how amphibious fishes cope with increased effective gravity and the inability to feed while out of water. In response to increased body weight on land (7 d), the gill skeleton of Kryptolebias marmoratus became stiffer, and I found increased abundance of many proteins typically associated with bone and cartilage growth in mammals. Conversely, there was no change in gill stiffness in the primitive ray-finned fish Polypterus senegalus after one week out of water, but after eight months the arches were significantly shorter and smaller. A similar pattern of gill reduction occurred during the tetrapod invasion of land, and my results suggest that genetic assimilation of gill plasticity could be an underlying mechanism. I also found proliferation of a gill inter-lamellar cell mass in P. senegalus out of water (7 d) that resembled gill remodelling in several other fishes, suggesting this may be an ancestral actinopterygian trait. Next, I tested the function of a calcified sheath that I discovered surrounding the gill filaments of >100 species of killifishes and some other percomorphs. -

Testing the potential of environmental DNA methods for surveying Lake Tanganyika's highly diverse fish communities Christopher James Doble A thesis submitted for the degree of Doctor of Philosophy Department of Genetics, Evolution and Environment University College London April 2020 1 Declaration I, Christopher James Doble, confirm the work presented in this thesis is my own. Where information has been derived from other sources, I confirm this has been indicated in the thesis. Christopher James Doble Date: 27/04/2020 2 Statement of authorship I planned and undertook fieldwork to the Kigoma region of Lake Tanganyika, Tanzania in 2016 and 2017. This included obtaining research permits, collecting environmental DNA samples and undertaking fish community visual survey data used in Chapters three and four. For Chapter two, cichlid reference database sequences were sequenced by Walter Salzburger’s research group at the University of Basel. I extracted required regions from mitochondrial genome alignments during a visit to Walter’s research group. Other reference sequences were obtained by Sanger sequencing. I undertook the DNA extractions and PCR amplifications for all samples, with the clean-up and sequencing undertaken by the UCL Sequencing facility. I undertook the method development, DNA extractions, PCR amplifications and library preparations for each of the next generation sequencing runs in Chapters three and four at the NERC Biomolecular Analysis Facility Sheffield. Following training by Helen Hipperson at the NERC Biomolecular Analysis Facility in Sheffield, I undertook the bioinformatic analysis of sequence data in Chapters three and four. I also carried out all the data analysis within each chapter. Chapters two, three and parts of four have formed a manuscript recently published in Environmental DNA (Doble et al. -

What Explains the Diversity of Sexually Selected Traits?
Biol. Rev. (2020), 95, pp. 847–864. 847 doi: 10.1111/brv.12593 Songs versus colours versus horns: what explains the diversity of sexually selected traits? John J. Wiens* and E. Tuschhoff Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ, 85721-0088, U.S.A. ABSTRACT Papers on sexual selection often highlight the incredible diversity of sexually selected traits across animals. Yet, few studies have tried to explain why this diversity evolved. Animals use many different types of traits to attract mates and outcom- pete rivals, including colours, songs, and horns, but it remains unclear why, for example, some taxa have songs, others have colours, and others horns. Here, we first conduct a systematic survey of the basic diversity and distribution of dif- ferent types of sexually selected signals and weapons across the animal Tree of Life. Based on this survey, we describe seven major patterns in trait diversity and distributions. We then discuss 10 unanswered questions raised by these pat- terns, and how they might be addressed. One major pattern is that most types of sexually selected signals and weapons are apparently absent from most animal phyla (88%), in contrast to the conventional wisdom that a diversity of sexually selected traits is present across animals. Furthermore, most trait diversity is clustered in Arthropoda and Chordata, but only within certain clades. Within these clades, many different types of traits have evolved, and many types appear to have evolved repeatedly. By contrast, other major arthropod and chordate clades appear to lack all or most trait types, and similar patterns are repeated at smaller phylogenetic scales (e.g.
