Morphometric, Molecular Phylogenetic and Gene Expression Approaches Towards the Understanding of the Adaptive Radiations of the East African Cichlids
Morphometric, Molecular Phylogenetic and Gene Expression Approaches towards the Understanding of the Adaptive Radiations of the East African Cichlids Dissertation zur Erlangung des akademischen Grades des Doktors der Naturwissenschaften (Dr. rer. nat.) an der Universitat Konstanz, Mathematisch-naturwissenschaftliche Sektion Fachbereich Biologie vorgelegt von Celine Clabaut, M.Sc. Konstanz, Dezember 2005 1 ACKNOWLEDGMENTS I first want to thank Prof. Axel Meyer for welcoming me in his laboratory and giving me the opportunity of completing a doctoral degree in the University of Konstanz. I also thank Dr. Walter Salzburger for getting me started on all the projects that could not have happened without his work. I am grateful for all the ideas he shared with me, and his availability to answer my questions. Dr. Paul Bunje gave me the chance of experiencing a fruitful collaboration by improving the morphometric work, and I am grateful to him for this (as well as all the corrections he did of my English writing). I am grateful to people belonging to the Meyer lab in general. I have never been denied or refused help, time, book or answers, each time I have been asking for them. I have to particularly acknowledge Arie and Dirk, since computer-related issues are the field where I have been more demanding, and Elke for being so efficient. I am so thankful to the friends I made here in Konstanz. It took a while for me to meet them, but they really made life here more enjoyable. Some even provided support in addition to fun, and I am particularly grateful to them. -
Depth Segregation and Diet Disparity Revealed by Stable Isotope Analyses
Hata et al. Zoological Letters (2015) 1:15 DOI 10.1186/s40851-015-0016-1 RESEARCH ARTICLE Open Access Depth segregation and diet disparity revealed by stable isotope analyses in sympatric herbivorous cichlids in Lake Tanganyika Hiroki Hata1*, Jyunya Shibata2,3, Koji Omori2, Masanori Kohda4 and Michio Hori5 Abstract Background: Lake Tanganyika in the African Great Rift Valley is known as a site of adaptive radiation in cichlid fishes. Diverse herbivorous fishes coexist on a rocky littoral of the lake. Herbivorous cichlids have acquired multiple feeding ecomorphs, including grazer, browser, scraper, and scooper, and are segregated by dietary niche. Within each ecomorph, however, multiple species apparently coexist sympatrically on a rocky slope. Previous observations of their behavior show that these cichlid species inhabit discrete depths separated by only a few meters. In this paper, using carbon (C) and nitrogen (N) stable isotope ratios as markers, we followed the nutritional uptake of cichlid fishes from periphyton in their feeding territories at various depths. Results: δ15N of fish muscles varied among cichlid ecomorphs; this was significantly lower in grazers than in browsers and scoopers, although δ15N levels in periphyton within territories did not differ among territorial species. This suggests that grazers depend more directly on primary production of periphyton, while others ingest animal matter from higher trophic levels. With respect to δ13C, only plankton eaters exhibited lower values, suggesting that these fishes depend on production of phytoplankton, while the others depend on production of periphyton. Irrespective of cichlid ecomorph, δ13C of periphyton correlated significantly with habitat depth, and decreased as habitat depth became deeper. -

Testing the Potential of Environmental DNA Methods for Surveying Lake Tanganyika's Highly Diverse Fish Communities Christopher J
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. -

It consists of many different levels with species richness as the most frequently used measure. Despite its generally lower species richness compared to littoral zones, the global importance of the pelagic realm in marine and freshwater ecosystems lies in the high level of productivity supporting fisheries worldwide. In terms of endemicity, Lake Tanganyika is one of the most exceptional freshwater study areas in the world. While dozens of studies focus on this lake’s cichlids as model organisms, our knowledge about the economically important fish species is still poor. Despite their important role in speciation processes, parasite taxa have been vastly ignored in the African Great Lakes including Lake Tanganyika for many years. -

Despite their rapid pace, speciation events were so far intuitively assumed to proceed in a bifurcating and tree-like fashion, even if they could not be resolved by gene phylogenies due to a lack of resolution. On the basis of phylogenetic analyses of the Tropheini, a lineage of endemic rock-dwelling cichlid fishes from Lake Tanganyika, we suggest a pathway of explosive speciation that accounts for a non-bifurcating manner of cladogenesis. -

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').
