Nigel’s research focus is on ecology, animal physiology and behaviour using the African mole-rat as his model animal. He and his co-workers have investigated the ecological and physiological factors that affect the control of reproduction and the evolution of sociality. Unlike other researchers investigating cooperative breeding in mammals, he has done so from a variety of perspectives. The strength of this multi-faceted approach is that it has led to an integrated understanding of reproductive suppression in mole-rats of a type that has not been achieved for any other taxa or group of taxa. His research has set the benchmark for our understanding of phylogenetic and ecological constraints regulating reproductive success and social evolution in mammalian species. His research record ranks him among the best researchers studying social regulation of reproduction in any group of mammals in the world. Nigel obtained his BSc Hons. in 1983 from the University of Bristol in the United Kingdom. After completing his PhD at the University of Cape Town in 1988, he was employed as a junior lecturer and senior researcher in zoology at the institution until 1995 when he was appointed as a senior lecturer in the department of zoology and entomology at the UP. He was promoted to full professor in 2001. Nigel holds an A rating by the National Research Foundation. He has been a visiting Professor at the School of Chemical and Biological Sciences, Queen Mary College, University of London since 2005 and more recently a visiting Professor at the Department of Zoology, King Saud University, Saudi Arabia. He has been awarded the UP Chancellor's Medal for his research twice as well as receiving the Exceptional Academic Achiever Award for the past sixteen years. He is a fellow of the Zoological Society of London, a fellow of the Royal Society of South Africa and a member of the Academy of Sciences of South Africa. He has been the recipient of the Gold medal from the Zoological Society of Southern Africa and the Havenga Prize for outstanding contributions to Life Sciences awarded by the Academy of Science and Arts of South Africa. UP awarded him the University of Pretoria Commemorative Research Medal for being one of the top 100 scientists in 100 years of its existence. In 2015 he was awarded an NSTF ESKOM-sponsored award for his outstanding contribution to Science, Engineering and Information Technology as a developer of research capacity, in 2016 he was made a fellow of the African Academy of Sciences, and in 2017 the University recognised him with the Vice Chancellor’s award for outstanding postgraduate supervision. Nigel has served as President of the Zoological Community of Southern Africa for two years. He is editor-in-chief of the Journal of Zoology, London and a past editor of Proceedings of the Royal Society of London Biological Sciences B. In 2013 he took on the handling editor position at Biology Letters another Royal Society journal. Nigel has published 365 papers in international peer-reviewed scientific journals, co-authored a specialist book published by Cambridge University Press and has penned twelve chapters in books. Nigel is the world leader in African mole-rat biology and in particular reproductive physiology. 2 39th ZSSA Congress 2019 Prof Barry Lovegrove University of KwaZulu-Natal Barry is Professor Emeritus at the University of KwaZulu-Natal. He obtained his PhD under the supervision of Gideon Louw from the University of Cape Town in 1987, where after he undertook post-doctoral studies at the University of California, Los Angeles, and Phillips University, Marburg, Germany, the latter as an Alexander von Humboldt Fellow. Barry is an evolutionary physiologist. He spent his whole career trying to understand the diversity of metabolic adaptations in birds and mammals. His work culminated in the book Fires of Life: Endothermy in Birds and Mammals (Yale University Press). In 2017 Barry gave the prestigious Irving-Scholander Memorial Lecture in Fairbanks, Alaska in anticipation of the book’s release. Barry is also the author of Living Deserts of Southern Africa (Fernwood Press), which he is currently updating. Barry is an NRF A-rated scientist. Prof Hugh Maclsaac University of Windsor, Canada Hugh is professor and senior Canada Research Chair in Aquatic Invasive Species at the Great Lakes Institute for Environmental Research, University of Windsor, Canada. Previously Hugh was Fisheries and Oceans Canada Invasive Species Research Chair, and Director of the Canadian Aquatic Invasive Species Network, a consortium of ~35 faculty across Canada. Hugh is a Distinguished Research Fellow of the Sino-Canada Research Center on Plateau Lakes at Yunnan University, China. Hugh has authored over 200 peer- reviewed papers and books. Hugh is interested in a variety of issues pertaining to invasive species, including analyses of vectors and pathways of introduction, genetic characterization and evolution, and impacts and mitigation. He developed conceptual and empirical models to describe how alien invasive species colonize the Laurentian Great Lakes and other aquatic ecosystems. Recent work addresses use of genetic markers to identify source and destination patterns, and how the problems of false positives and false negatives are affected with this approach. 3 39th ZSSA Congress 2019 Presentation Abstracts MONDAY 8 JULY Plenary Teasing apart the mechanisms of socially-induced infertility in non-reproductive naked and Damaraland mole-rats occurring in harsh arid environments.

    Body shape evolution of African/Asian minnows of the genus Labeo Cuvier 1817 (Cyprinidae, Labeonini) and variations in Labeo parvus. by Tobit Dja Liyandja Liyandja A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama August 04, 2018 Keywords: geometric morphometrics, body shape, phylogeny, convergent evolution, Labeo Copyright 2018 by Tobit D. L. Liyandja Approved by Jonathan W. Armbruster, Chair, Professor of Biological Sciences and Curator of Fishes Stephen A. Bullard, Associate Professor Jamie R. Oaks, Assistant Professor Abstract Morphological variation or similarities among organisms are not only a result of common evolutionary history but can also emerge because of convergent adaptations to similar habitats. Therefore, an organism’s morphology is strongly correlated with environmental gradients and plays an important role in growth, survival, and reproduction. In aquatic habitats for instance, body shape plays a significant role in foraging, locomotion, defense, and habitat exploitation. Understanding shape variation and evolution within a group of organisms can provide insights about strategies for habitat colonization, food resource use, and even species diversity within a group. Herein, I combined geometric morphometrics, molecular phylogeny, and phylogenetic comparative methods to assess body shape variation and evolution among species of the African/Asian minnows of the genus Labeo. Additionally, I assessed species diversity and distribution patterns within Labeo parvus. I found that Labeo body shape varies significantly across species and clades. The greatest variation in body shape among Labeo species and clades occurs in body depth and width. I also found that the similarities in body shape observed between some species are not always due to common evolutionary history.

  • Genetic Diversity, Evolutionary Relationships and Conservation of Southern African Labeo Fishes in Relation To
    Genetic diversity, evolutionary relationships and conservation of southern African Labeo fishes in relation to water management A thesis submitted in fulfilment of the requirements for the degree of DOCTOR OF PHILOSOPHY of RHODES UNIVERSITY by MPHO RAMOEJANE October 2016 ABSTRACT Labeo spp. are large, herbivorous fishes that are important components of aquatic ecosystems and are a high conservation priority in South Africa. This thesis contributes to determination of conservation priorities for Labeo umbratus (Smith 1841) by resolving the taxonomic status of this species in the evolutionary context of southern African Labeo spp., assessing the presence of unique lineages in historically isolated river basins, and assessing the threat of intra- and interspecific hybridisation associated with introductions. Phylogenetic analyses of five DNA sequence data sets (cytochrome c oxidase subunit I gene [COI], cytochrome b gene [Cyt b], Recombination activating gene 1 [Rag1], COI+Rag1 and COI+Cyt b+Rag1) showed that the Labeo umbratus group (sensu Reid, 1985), which comprises the species Labeo umbratus, Labeo capensis (Smith 1841), Labeo seeberi Gilchrist and Thompson 1911 and Labeo rubromaculatus Gilchrist and Thompson 1913, is monophyletic, morphologically distinct and geographically disjunct from other African Labeo spp. groups except in the Tugela River system were L. rubromaculatus co-occurs with Labeo molybdinus Du Plessis 1963. Phylogeographic analysis of mitochondrial DNA (Cyt b) sequence data demonstrated that the populations of the L. umbratus from the Orange and the southward-flowing river systems are reciprocally monophyletic and were identified as evolutionary significant units. The populations in the southward-flowing river systems were further divided into southwestern (Gourits and Gamtoos) and southeastern (Sundays, Bushmans, Great Fish, Keiskamma, Buffalo and Nahoon) polyp hyletic sublineages.

O. Box 350100, Chilanga, Zambia (Received 6 February 2014, Accepted 30 June 2014) Labeo rosae, a species with a native range in Southern Africa, was discovered in the Congo basin by re-identification of two museum specimens previously identified as Labeo mesops. The occurrence of this species in the upper Congo implies a range extension of the species of more than 1000 km. Although the species’ distribution is mirrored by that of some other Cypriniformes, its occurrence in the Congo might be due to introduction by humans. © 2014 The Fisheries Society of the British Isles Key words: Africa; biogeography; Labeo altivelis; Labeo mesops; reservoir lake; taxonomy. Labeo Cuvier 1816 is, in Africa, the third most diverse cyprinid genus, after Barbus Barbus Cuvier & Cloquet 1816 and Labeobarbus Rüppell 1835 (Reid, 1985; Skelton et al., 1991). Species of Labeo are herbivores that feed on the algal growth covering the substratum. For this, they possess special adaptations such as an inferior, sucker-like mouth with folded lips and a hardened edge (Reid, 1985; Skelton, 2001).

The goal of the present study was to assess the performance of COI in discrimi- nating specimens of the fish family Cyprinidae in Africa, and to explore whether COI-phylogeny can be reliably used for phylogenetic comparative analysis. The main objective was to analyse a matrix of COI sequences for 315 specimens from 15 genera of African Cyprinidae using various distance-based identifi- cation methods alongside multiple tests of DNA barcode efficacy (barcode gap, species monophyly on NJ tree).
