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. -

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. -

A New Dwarf Cichlid (Perciformes) from Nigeria
A new dwarf cichlid (Perciformes) from Nigeria by Anton LAMBOJ (1) Abstract. – Pelvicachromis silviae, a new cichlid species, is described. It differs from congeners by unique col- oration of females and a combination of morphological characters, e.g. greater body depth, shorter snout length, greater eye orbit diameter and several other meristic parameters. The species occurs in the lower Niger River system and seems to represent within the genus a closer relative to P. subocellatus. Résumé. – Un nouveau cichlidé nain (Perciformes) du Nigéria.

Mitochondrial genomes of 26 cichlid species were amplified by long-range PCR followed by the 454 pyrosequencing on a GS Roche Junior platform. The primers for long-range PCR were designed specifically in the mitogenomic regions with low interspecific variability. The whole mitogenome of most species was amplified as three fragments using the following primer sets: for the region between position 2 500 bp and 7 300 bp (of mitogenome starting with tRNA-Phe), we used forward primers ZM2500F (5'-ACG ACC TCG ATG TTG GAT CAG GAC ATC C-3'), L2508KAW (Kawaguchi et al. 2001) or S-LA-16SF (Miya & Nishida 2000) and reverse primer ZM7350R (5'-TTA AGG CGT GGT CGT GGA AGT GAA GAA G-3').

Licensed under Creative Commons Attribution-Share Alike 3.0 Unported. Available: https://commons.wikimedia.org/wiki/File:Pelvicachromis_pulcher_(female)_02.jpg. (April 2019). 1 Native Range and Status in the United States Native Range From Froese and Pauly (2019): “Africa: eastern Benin, southern Nigeria and western Cameroon [Stiassny et al. 2008].” 1 From Lalèyè et al. (2010): “Central Africa: In Lower Guinea, Pelvicachromis pulcher is known from the Cross River basin, and from western Cameroon (Ndonga). Western Africa: In Western Africa, this species is known from Southwestern Nigeria to the River Cross. Also reported from Sierra Leone but this needs to be confirmed.” Status in the United States From Froese and Pauly (2019): “Established in reservoir or pond habitats on Oahu, Hawaii, First released or discovered in 1984.” Pelvicachromis pulcher falls within Group I of New Mexico’s Department of Game and Fish Director’s Species Importation List (New Mexico Department of Game and Fish 2010). Group I species “are designated semi-domesticated animals and do not require an importation permit.” P. pulcher is in trade within the United States (e.g. Live Aquaria 2021). Means of Introductions in the United States From Froese and Pauly (2019): “ornamental” Remarks No additional remarks. 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing According to Fricke et al. (2019), Pelvicachromis pulcher (Boulenger 1901) is the current valid name for this species.
