Abstract Background: The tribe Lamprologini is the major substrate breeding lineage of Lake Tanganyika's cichlid species flock. Among several different life history strategies found in lamprologines, the adaptation to live and breed in empty gastropod shells is probably the most peculiar.

  • 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.

  • Direct Benefits and Evolutionary Transitions to Complex Societies
    ARTICLES PUBLISHED: 18 APRIL 2017 | VOLUME: 1 | ARTICLE NUMBER: 0137 Direct benefits and evolutionary transitions to complex societies Cody J. Dey1, 2 †, Constance M. O’Connor1 †, Holly Wilkinson3, Susanne Shultz3, Sigal Balshine1 and John L. Fitzpatrick3, 4* The selective forces that drive the evolution of cooperation have been intensely debated. Evolutionary transitions to coop- erative breeding, a complex form of cooperation, have been hypothesized to be linked to low degrees of promiscuity, which increases intragroup relatedness and the indirect (that is, kin selected) benefits of helping. However, ecological factors also promote cooperative breeding, and may be more important than relatedness in some contexts. Identifying the key evolution- ary drivers of cooperative breeding therefore requires an integrated assessment of these hypotheses. Here we show, using a phylogenetic framework that explicitly evaluates mating behaviours and ecological factors, that evolutionary transitions to cooperative breeding in cichlid fishes were not associated with social monogamy. Instead, group living, biparental care and diet type directly favoured the evolution of cooperative breeding. Our results suggest that cichlid fishes exhibit an alternative path to the evolution of complex societies compared to other previously studied vertebrates, and these transitions are driven primarily by direct fitness benefits. ooperative breeding, where individuals in social groups pro- evolution of cooperative societies, because social monogamy is also vide care for offspring that are not their own, is a complex favoured under particular ecological factors14 and therefore apparent Cform of sociality1 that has arisen repeatedly across the animal relationships between monogamy and cooperative breeding could kingdom.

  • Cichlids Correct Feeding for a Good Husbandry
    Cichlids correct feeding for a good husbandry www.JBL.de Dear Cichlid-friend, We have produced this brochure in order to make easier for you to give your cichlids the right food and care for this species. With about 2.000 varieties of cichlid, all types of eating habits are represented here: from plant-eaters to omnivorous species to pure predators. Giving the right food makes sense, as the wrong food will be excreted by the fish un- digested (or partially digested). Incorrect feeding is proven to lead to increased water pollution. Clean (unpolluted) water free of ammonium/ ammonia and nitrite is a basic requirement of successful aquarium- keeping – special water qualities are often only essential for breeding. Wishing you continued pleasure from this fascinating group of fish!

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'). The region between 7 300 bp and 12 300 bp was amplified using primers ZM7300F (5'-GCA CAT CCC TCC CAA CTA GGW TTT CAA GAT GC-3') and ZM12300R (5'-TTG CAC CAA GAG TTT TTG GTT CCT AAG ACC-3').
