We suggest that the integration of genomic Sexual selection Speciation approaches with ecological and behavioural studies, across the entire cichlid family and beyond it, will contribute to the utility of the cichlid model system for understanding the evolution of biological diversity. -
Removal of Reproductive Suppression Reveals Latent Sex Differences In
Swift-Gallant et al. Biology of Sex Differences (2015) 6:31 DOI 10.1186/s13293-015-0050-x RESEARCH Open Access Removal of reproductive suppression reveals latent sex differences in brain steroid hormone receptors in naked mole-rats, Heterocephalus glaber Ashlyn Swift-Gallant1, Kaiguo Mo1, Deane E. Peragine1, D. Ashley Monks1,2 and Melissa M. Holmes1,2,3* Abstract Background: Naked mole-rats are eusocial mammals, living in large colonies with a single breeding female and 1–3 breeding males. Breeders are socially dominant, and only the breeders exhibit traditional sex differences in circulating gonadal steroid hormones and reproductive behaviors. Non-reproductive subordinates also fail to show sex differences in overall body size, external genital morphology, and non-reproductive behaviors. However, subordinates can transition to breeding status if removed from their colony and housed with an opposite-sex conspecific, suggesting the presence of latent sex differences. Here, we assessed the expression of steroid hormone receptor and aromatase messenger RNA (mRNA) in the brains of males and females as they transitioned in social and reproductive status. Methods: We compared in-colony subordinates to opposite-sex subordinate pairs that were removed from their colony for either 1 day, 1 week, 1 month, or until they became breeders (i.e., produced a litter). Diencephalic tissue was collected and mRNA of androgen receptor (Ar), estrogen receptor alpha (Esr1), progesterone receptor (Pgr), and aromatase (Cyp19a1) was measured using qPCR. Testosterone, 17β-estradiol, and progesterone from serum were also measured. Results: As early as 1 week post-removal, males exhibited increased diencephalic Ar mRNA and circulating testosterone, whereas females had increased Cyp19a1 mRNA in the diencephalon. -

Olfactory Sensitivity to Steroid Glucuronates in Mozambique Tilapia

M. Canário1 and Peter C. Hubbard1,* ABSTRACT improve fertility to enhance reproductive success (Stacey, 2010; Cichlids offer an exciting opportunity to understand vertebrate Stacey and Sorensen, 2005). Pheromones may be composed of a speciation; chemical communication could be one of the drivers of single or multiple component(s) and are detected by olfactory African cichlid radiation. Chemical signals mediate key aspects in the receptors from which the signal is relayed to specific brain areas that lives of vertebrates and often are species specific. Dominant male integrate the information and trigger the appropriate behavioural Mozambique tilapia [Oreochromis mossambicus (Peters 1852)] and/or endocrine response.

Constraints on the Timescale of Animal Evolutionary History
Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Color Pattern Variation in Cichla Temensis (Perciformes: Cichlidae): Resolution Based on Morphological, Molecular, and Reproductive Data
Neotropical Ichthyology, 10(1): 59-70, 2012 Copyright © 2012 Sociedade Brasileira de Ictiologia Color pattern variation in Cichla temensis (Perciformes: Cichlidae): Resolution based on morphological, molecular, and reproductive data Paul Reiss1, Kenneth W. Able2, Mario S. Nunes3 and Tomas Hrbek3 Morphological variants of Cichla temensis, readily differentiated by their striking color pattern differences, are found in several Amazon basin flood pulse river systems. The adult variants have at times been thought to represent different species or sexual dimorphism. A three part study was performed in two regions in Brazil (rio Igapó Açú and rio Caures) to elucidate the nature of the variants. In part one; selected diagnostic morphometric characters were compared intraspecifically among the variants and interspecifically with C. monoculus and C. orinocensis. All of the C. temensis variants were found to differ significantly from their sympatric congeners while not differing among each other. In part two, mitochondrial DNA samples were compared intraspecifically among the variants and interspecifically with their sympatric congeners. There were no diagnostic molecular synapomorphies that would unambiguously distinguish the variants and all C. temensis variants were clearly diagnosable and divergent from their sympatric congeners. In part three, color pattern variation in both sexes was compared to a gonadosomatic index (GSI). A significant correlation between color pattern variation and gonadosomatic index was found. The results of this study demonstrate that Cichla temensis variants are confirmed to be members of a single species and that the variation does not represent a sexual dimorphism. The color pattern variation is a cyclically occurring secondary sexual characteristic and is indicative of the specific degree of an individual’s seasonal sexual maturation. -

AMEMIYA , AND AXEL MEYER 1Lehrstuhl fu¨r Zoologie und Evolutionsbiologie, Department of Biology, University of Konstanz, 78457 Konstanz, Germany 2Benaroya Research Institute at Virginia Mason, Seattle, Washington 98101 ABSTRACT A BAC library was constructed from Astatotilapia burtoni, a haplochromine cichlid that is found in Lake Tanganyika, East Africa, and its surrounding rivers. The library was generated from genomic DNA of blood cells and comprises 96,768 individual clones. Its median insert size is 150 kb and the coverage is expected to represent about 14 genome equivalents. The coverage evaluation was based on genome size estimates that were obtained by flow cytometry. In addition, hybridization screens with five probes largely corroborate the above coverage estimate, although the number of clones ranged from 5 to 22 authenticated clones per single copy probe. The BAC library described here is expected to be useful to the scientific community interested in cichlid genomics as an important resource to gain new insights into the rapid evolution of the great species diversity of haplochromine cichlid fishes.

Competition and distribution model predictions vary based on dominance hierarchies, but most assume differences in dominance are constant across habitats. More recent evidence suggests dominance and competitive advantages may vary based on habitat. We quantified dominance interactions between two species of sharks Carcharhinus amblyrhynchos and Carcharhinus melanopterus, across two different habitats, fore reef and back reef, at a remote Pacific atoll. We used Baited Remote Underwater Video (BRUV) to observe dominance behaviors and quantified the number of aggressive interactions or bites to the BRUVs from either species, both separately and in the presence of one another. Blacktip reef sharks were the most abundant species in either habitat, and there was significant negative correlation between their relative abundance, bites on BRUVs, and the number of grey reef sharks. Although this trend was found in both habitats, the decline in blacktip abundance with grey reef shark presence was far more pronounced in fore reef habitats. We show that the presence of one shark species may limit the feeding opportunities of another, but the extent of this relationship is habitat specific. Future competition models should consider habitat-specific dominance or competitive interactions.
