Experimental copper exposure, but not heat stress, leads to elevated intraovarian thyroid hormone levels in three-spined sticklebacks (Gasterosteus aculeatus).

Ecotoxicology 2020 Nov 25;29(9):1431-1440. Epub 2020 Sep 25.

Department of Biology, University of Turku, Turku, Finland.

Climate change and pollution are some of the greatest anthropogenic threats to wild animals. Transgenerational plasticity-when parental exposure to environmental stress leads to changes in offspring phenotype-has been highlighted as a potential mechanism to respond to various environmental and anthropogenic changes across taxa. Transgenerational effects may be mediated via multiple mechanisms, such as transfer of maternal hormones to eggs/foetus. Read More

Effects of chronic exposure to a pharmaceutical mixture on the three-spined stickleback (gasterosteus aculeatus) population dynamics in lotic mesocosms.

Aquat Toxicol 2020 Jul 1;224:105499. Epub 2020 May 1.

Unité METO (Modèles pour l'Ecotoxicologie et la Toxicologie), UMR-I 02 SEBIO, INERIS, 60550, Verneuil en Halatte, France. Electronic address:

Pharmaceutical substances are ubiquitous in the aquatic environment and their concentration levels typically range from ng/L up to several μg/L. Furthermore, as those compounds are designed to be highly biologically active, assessing their impacts on non-target organisms is important. Here, we conducted a mesocosm experiment testing a mixture of five pharmaceuticals (diclofenac, carbamazepine, irbesartan, acetaminophen and naproxen) on fish, three-spined stickleback (Gasterosteus aculeatus).

A High-Quality Assembly of the Nine-Spined Stickleback (Pungitius pungitius) Genome.

Genome Biol Evol 2019 11;11(11):3291-3308

Ecological Genetics Research Unit, Research Programme in Organismal and Evolutionary Biology, Faculty of Biological and Environmental Sciences, University of Helsinki, Finland.

The Gasterosteidae fish family hosts several species that are important models for eco-evolutionary, genetic, and genomic research. In particular, a wealth of genetic and genomic data has been generated for the three-spined stickleback (Gasterosteus aculeatus), the "ecology's supermodel," whereas the genomic resources for the nine-spined stickleback (Pungitius pungitius) have remained relatively scarce. Here, we report a high-quality chromosome-level genome assembly of P. Read More

Attractive male sticklebacks carry more oxidative DNA damage in the soma and germline.

J Evol Biol 2020 01 7;33(1):121-126. Epub 2019 Nov 7.

Departamento de Ecoloxía e Bioloxía Animal, Universidade de Vigo, Vigo, Spain.

Trade-offs between the expression of sexual signals and the maintenance of somatic and germline tissues are expected when these depend upon the same resources. Despite the importance of sperm DNA integrity, its trade-off with sexual signalling has rarely been explored. We experimentally tested the trade-off between carotenoid-based sexual coloration and oxidative DNA damage in skeletal muscle, testis and sperm by manipulating reproductive schedule (early vs. Read More

Interpretation of sexual secondary characteristics (SSCs) in regulatory testing for endocrine activity in fish.

Chemosphere 2020 Feb 24;240:124943. Epub 2019 Sep 24.

Plymouth University, School of Life Sciences, Drake Circus, Plymouth, PL4 8AA, UK.

Secondary sexual characteristics (SSCs) are important features that have evolved in many fish species because of inter-individual competition for mates. SSCs are crucial not only for sexual selection, but also for other components of the reproductive process and parental care. Externally, they are especially clear in males (for instance, tubercles, fatpad, anal finnage, colouration) but are also externally present in the females (for instance, ovipositor). Read More

Impact of confinement and food access restriction on the three-spined stickleback (Gasterosteus aculeatus, L.) during caging: a multi-biomarker approach.

Fish Physiol Biochem 2019 Aug 21;45(4):1261-1276. Epub 2019 Jun 21.

UMR-I 02 SEBIO (Stress Environnementaux et Biosurveillance des milieux aquatiques), Institut National de l'Environnement et des Risques (INERIS), BP 2, 60550, Verneuil-en-Halatte, France.

Caging is an active biomonitoring strategy that employs a sentinel species, sometimes a species naturally absent from the studied site, in the surveillance of water bodies to verify whether biota may be at risk. The main advantage of caging is the possibility to standardize several biotic and abiotic parameters. However, little knowledge is available about the effects of confinement on physiology and metabolism of caged organisms. Read More

Female assortative mate choice functionally validates synthesized male odours of evolving stickleback river-lake ecotypes.

Biol Lett 2018 12;14(12):20180730

1 Max Planck Institute for Evolutionary Biology , August-Thienemann-Strasse 2, 24306 Plön , Germany.

During mate choice decisions, females of many vertebrates use male olfactory cues to achieve immunogenetic optimality of their offspring. Three-spined sticklebacks ( Gasterosteus aculeatus) populating habitats that differ in their parasite communities evolve locally adapted combinations of genetic variants encoded at the major histocompatibility complex (MHC). Such adaptation confers optimal resistance to the local parasite fauna. Read More

Variation in sexual brain size dimorphism over the breeding cycle in the three-spined stickleback.

J Exp Biol 2019 04 9;222(Pt 7). Epub 2019 Apr 9.

Ecological Genetics Research Unit, Organismal and Evolutionary Biology Research Programme, Faculty of Biological and Environmental Sciences, University of Helsinki, PO Box 65, FI-00014 Helsinki, Finland.

Snapshot analyses have demonstrated dramatic intraspecific variation in the degree of brain sexual size dimorphism (SSD). Although brain SSD is believed to be generated by the sex-specific cognitive demands of reproduction, the relative roles of developmental and population-specific contributions to variation in brain SSD remain little studied. Using a common garden experiment, we tested for sex-specific changes in brain anatomy over the breeding cycle in three-spined stickleback () sampled from four locations in northern Europe. Read More

miRNA analysis with Prost! reveals evolutionary conservation of organ-enriched expression and post-transcriptional modifications in three-spined stickleback and zebrafish.

Sci Rep 2019 03 8;9(1):3913. Epub 2019 Mar 8.

Institute of Neuroscience, University of Oregon, Eugene, OR, 97403, USA.

MicroRNAs (miRNAs) can have organ-specific expression and functions; they can originate from dedicated miRNA genes, from non-canonical miRNA genes, or from mirror-miRNA genes and can also experience post-transcriptional variation. It remains unclear, however, which mechanisms of miRNA production or modification are organ-specific and the extent of their evolutionary conservation. To address these issues, we developed the software Prost! (PRocessing Of Short Transcripts), which, among other features, helps quantify mature miRNAs, accounts for post-transcriptional processing, such as nucleotide editing, and identifies mirror-miRNAs.

Unravelling paralogous gene expression dynamics during three-spined stickleback embryogenesis.

Sci Rep 2019 03 6;9(1):3752. Epub 2019 Mar 6.

Institute for Marine Biology, Biotechnology and Aquaculture (IMBBC), Hellenic Centre for Marine Research (HCMR), Heraklion, Greece.

Development requires the implementation of a plethora of molecular mechanisms, involving a large set of genes to ensure proper cell differentiation, morphogenesis of tissues and organs as well as the growth of the organism. Genome duplication and resulting paralogs are considered to provide the raw genetic materials important for new adaptation opportunities and boosting evolutionary innovation. The present study investigated paralogous genes, involved in three-spined stickleback (Gasterosteus aculeatus) development. Read More

Internal embryonic development in a non-copulatory, egg-laying teleost, the three-spined stickleback, Gasterosteus aculeatus.

Sci Rep 2019 02 20;9(1):2395. Epub 2019 Feb 20.

School of Life Sciences, University of Nottingham, Nottingham, NG7 2RD, UK.

The switch from egg-laying to retaining and giving birth to live young is a major transition in the history of life. Despite its repeated evolution across the fishes, records of intermediate phenotypes are vanishingly rare, with only two known cases in existence of normally egg-laying fish species retaining embryos within the ovaries. We report the discovery of a third occurrence, in which well-developed embryos were found in the ovaries of a three-spined stickleback (Gasterosteus aculeatus), a non-copulatory, normally oviparous species.

Ovarian fluid in the three-spined stickleback Gasterosteus aculeatus: effects of egg overripening and sex steroid treatment.

J Fish Biol 2019 Mar;94(3):446-457

Department of Zoology, Stockholm University, Stockholm, Sweden.

The ovarian fluid properties of the three-spined stickleback Gasterosteus aculeatus were studied in overripe and non-overripe ovulated female sticklebacks and in females that were implanted with Silastic capsules containing testosterone (T), oestradiol (E2), 17,20β-dihydroxypregn-4-en-3-one (17,20β-P) or progesterone (P4) into the abdominal cavity. Overripe females had less ovarian fluid than non-overripe females, but with higher dry mass, higher protein concentration and lower viscosity. T and 17,20β-P increased the amount of ovarian fluid and the fluid protein concentration was increased by 17,20β-P. Read More

Altered non-reproductive behavior and feminization caused by developmental exposure to 17α-ethinylestradiol persist to adulthood in three-spined stickleback (Gasterosteus aculeatus).

Aquat Toxicol 2019 Feb 28;207:142-152. Epub 2018 Nov 28.

School of Natural Sciences, Technology and Environmental Studies, Södertörn University, Huddinge, Sweden.

The synthetic estrogen 17α-ethinylestradiol (EE), ubiquitous in the aquatic environment and commonly detected in sewage effluents, interferes with the endocrine system in multiple ways. Exposure during sensitive windows of development causes persistent effects on fertility, reproductive and non-reproductive behavior in mammals and fish. In the present study, three-spined stickleback (Gasterosteus aculeatus) were exposed to nominal 0 and 20 ng/L EE from fertilization to 7 weeks post-hatch. Read More

Variation in female aggression in 2 three-spined stickleback populations with female throat and spine coloration.

Curr Zool 2018 Jun 7;64(3):345-350. Epub 2018 Mar 7.

Department of Biology, East Carolina University, Greenville, NC 27858, USA.

Despite growing interest in female ornament evolution, we still have a rudimentary understanding of female display traits relative to similar traits in males. Under one popular adaptive scenario, female ornaments are hypothesized to function in female-female competition and serve as badges of status, such that their expression is linked with elevated aggression in some cases. In this study, we investigated the relationship between 2 female ornaments-male-like red throat color and red spine coloration-and female aggression in 2 independently derived stream-resident populations of three-spined stickleback .

Cryptic haplotype-specific gamete selection yields offspring with optimal MHC immune genes.

Evolution 2018 11 24;72(11):2478-2490. Epub 2018 Sep 24.

Department of Evolutionary Ecology, Max Planck Institute for Evolutionary Biology, August-Thienemann-Str. 2, 24306 Plön, Germany.

Females choose specific mates in order to produce fitter offspring. However, several factors interfere with females' control over fertilization of their eggs, including sneaker males and phenotypically unpredictable allele segregation during meiosis. Mate choice at the individual level thus provides only a poor approximation for obtaining the best genetic match. Read More

Modelling the effect of season, sex, and body size on the three-spined stickleback, Gasterosteus aculeatus, cellular innate immunomarkers: A proposition of laboratory reference ranges.

Sci Total Environ 2019 Jan 27;648:337-349. Epub 2018 Jul 27.

Institut National de l'Environnement Industriel et des Risques (INERIS), UMR-I 02 SEBIO, Parc Technologique Alata, BP 2, 60550 Verneuil-en-Halatte, France. Electronic address:

Innate immunomarkers reflect both environmental contamination and fish health status, providing useful information in environmental risk assessment studies. Nevertheless, the lack of knowledge about the effect of confounding factors can lead to data misinterpretation and false diagnoses. The aim of this study was to evaluate the impact of three confounding factors (season, sex and body size) on three-spined stickleback innate immunomarkers in laboratory conditions. Read More

Good parenting may not increase reproductive success under environmental extremes.

J Evol Biol 2018 11 19;31(11):1638-1646. Epub 2018 Aug 19.

Department of Neuroscience, Psychology and Behaviour, College of Medicine, Biological Sciences and Psychology, University of Leicester, Leicester, UK.

For species exhibiting parental care, the way in which parents adjust care behaviour to compensate for environmental change potentially influences offspring survival and, ultimately, population viability. Using the three-spined stickleback (Gasterosteus aculeatus) - a species in which males provide parental care by building and tending a nest and fanning the eggs - we examined how low dissolved oxygen (DO) levels affect paternal care, embryo development and survival. Although levels of nest tending were unaffected by DO level, we found that larger males fanned their embryos more under low oxygen conditions. Read More

Cross-species systems analysis of evolutionary toolkits of neurogenomic response to social challenge.

Genes Brain Behav 2019 01 16;18(1):e12502. Epub 2018 Jul 16.

Carl R. Woese Institute for Genomic Biology, University of Illinois at Urbana-Champaign, Urbana, Illinois.

Social challenges like territorial intrusions evoke behavioral responses in widely diverging species. Recent work has showed that evolutionary "toolkits"-genes and modules with lineage-specific variations but deep conservation of function-participate in the behavioral response to social challenge. Here, we develop a multispecies computational-experimental approach to characterize such a toolkit at a systems level. Read More

The Influence of Rearing on Behavior, Brain Monoamines, and Gene Expression in Three-Spined Sticklebacks.

Brain Behav Evol 2018 29;91(4):201-213. Epub 2018 Jun 29.

Department of Physics, Chemistry and Biology, IFM Biology, Linköping University, Linköping, Sweden.

The causes of individual variation in behavior are often not well understood, and potential underlying mechanisms include both intrinsic and extrinsic factors, such as early environmental, physiological, and genetic differences. In an exploratory laboratory study, we raised three-spined sticklebacks (Gasterosteus aculeatus) under 4 different environmental conditions (simulated predator environment, complex environment, variable social environment, and control). We investigated how these manipulations related to behavior, brain physiology, and gene expression later in life, with focus on brain dopamine and serotonin levels, turnover rates, and gene expression.

Otolith development in wild populations of stickleback: Jones & Hynes method does not apply to most populations.

J Fish Biol 2018 Aug;93(2):272-281

School of Life Sciences, University of Nottingham, University Park, Nottingham, UK.

This paper critiques Jones & Hynes (1950) findings by analysing sequential samples of otoliths from three wild populations of Gasterosteus aculeatus from North Uist, Scotland and Nottingham, England. Contrary to Jones & Hynes (1950), but coincident with the finding of later researchers, our results showed that no true translucent ring formed in the otolith of G. aculeatus during their first summer.

The genomic landscape at a late stage of stickleback speciation: High genomic divergence interspersed by small localized regions of introgression.

PLoS Genet 2018 May 23;14(5):e1007358. Epub 2018 May 23.

Division of Ecological Genetics, Department of Population Genetics, National Institute of Genetics, Mishima, Shizuoka, Japan.

Speciation is a continuous process and analysis of species pairs at different stages of divergence provides insight into how it unfolds. Previous genomic studies on young species pairs have revealed peaks of divergence and heterogeneous genomic differentiation. Yet less known is how localised peaks of differentiation progress to genome-wide divergence during the later stages of speciation in the presence of persistent gene flow. Read More

Horizontal transmission of the ectoparasite Gyrodactylus arcuatus (Monogenea: Gyrodactylidae) to the next generation of the three-spined stickleback Gasterosteus aculeatus.

Folia Parasitol (Praha) 2018 Apr 19;65. Epub 2018 Apr 19.

Faculty of Biology, University of Gdansk, Poland This article contains supporting information (S1-S4) online at http://folia.paru.cas.cz/suppl/2018-65-006.pdf.

In the parthenogenetic monogeneans of the genus Gyrodactylus Nordmann, 1832, the genetic diversity within or between hosts is determined by the relative roles of lateral transmission and clonal propagation. Clonality and limited transmission lead to high-amplitude metapopulation dynamics and strong genetic drift. In Baltic populations of the three-spined stickleback Gasterosteus aculeatus Linnaeus, the local mitochondrial diversity of Gyrodactylus arcuatus Bychowsky, 1933 is very high, and spatial differentiation weak.

Long-term UVB exposure promotes predator-inspection behaviour in a fish.

Biol Lett 2017 Dec;13(12)

Institute for Evolutionary Biology and Ecology, University of Bonn, An der Immenburg 1, 53121 Bonn, Germany.

Ultraviolet-B radiation (UVB) reaching the earth's surface has increased due to human-caused stratospheric ozone depletion. Whereas the harmful effects of UVB on aquatic organisms are well studied at the molecular and cellular level, recent studies have also begun to address behavioural changes caused by sublethal amounts of UVB. However, the behavioural consequences of long-term exposure to ecologically relevant UVB levels over several life stages are virtually unknown, particularly with regard to predator-prey behaviour.

Thermal conditions during early life influence seasonal maternal strategies in the three-spined stickleback.

BMC Ecol 2017 11 10;17(1):34. Epub 2017 Nov 10.

Departamento de Ecoloxía e Bioloxía Animal, Universidade de Vigo, 36310, Vigo, Spain.

Background: Conditions experienced by a female during early life may affect her reproductive strategies and maternal investment later in life. This effect of early environmental conditions is a potentially important mechanism by which animals can compensate for the negative impacts of climate change. In this study, we experimentally tested whether three-spined sticklebacks (Gasterosteus aculeatus) change their maternal strategy according to environmental temperatures experienced earlier in life.

Developmental exposure to the SSRI citalopram causes long-lasting behavioural effects in the three-spined stickleback (Gasterosteus aculeatus).

Ecotoxicology 2018 Jan 23;27(1):12-22. Epub 2017 Oct 23.

School of Natural Sciences, Technology and Environmental Studies, Södertörn University, Alfred Nobels allé 7, SE-141 89, Huddinge, Sweden.

Selective Serotonin re-uptake inhibitors (SSRIs) are a class of psychotropic drugs used to treat depression in both adolescents and pregnant or breast-feeding mothers as well as in the general population. Recent research on rodents points to long-lasting behavioural effects of pre- and perinatal exposure to SSRIs which last into adulthood. In fish however, studies on effects of developmental exposure to SSRIs appears to be non-existent. Read More
