Evolution after whole genome duplication: teleost microRNAs.

Mol Biol Evol 2021 Apr 19. Epub 2021 Apr 19.

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

microRNAs (miRNAs) are important gene expression regulators implicated in many biological processes, but we lack a global understanding of how miRNA genes evolve and contribute to developmental canalization and phenotypic diversification. Whole genome duplication events likely provide a substrate for species divergence and phenotypic change by increasing gene numbers and relaxing evolutionary pressures. To understand the consequences of genome duplication on miRNA evolution, we studied miRNA genes following the Teleost Genome Duplication (TGD). Read More

"Micropersonality" traits and their implications for behavioral and movement ecology research.

Ecol Evol 2021 Apr 22;11(7):3264-3273. Epub 2021 Feb 22.

Department of Biosciences College of Science Swansea University Swansea UK.

Many animal personality traits have implicit movement-based definitions and can directly or indirectly influence ecological and evolutionary processes. It has therefore been proposed that animal movement studies could benefit from acknowledging and studying consistent interindividual differences (personality), and, conversely, animal personality studies could adopt a more quantitative representation of movement patterns.Using high-resolution tracking data of three-spined stickleback fish () we examined the repeatability of four movement parameters commonly used in the analysis of discrete time series movement data (time stationary, step length, turning angle, burst frequency) and four behavioral parameters commonly used in animal personality studies (distance travelled, space use, time in free water, and time near objects).

Adaptive Divergence under Gene Flow along an Environmental Gradient in Two Coexisting Stickleback Species.

Genes (Basel) 2021 Mar 18;12(3). Epub 2021 Mar 18.

Faculty of Biosciences and Aquaculture, Nord University, N-8049 Bodø, Norway.

There is a general and solid theoretical framework to explain how the interplay between natural selection and gene flow affects local adaptation. Yet, to what extent coexisting closely related species evolve collectively or show distinctive evolutionary responses remains a fundamental question. To address this, we studied the population genetic structure and morphological differentiation of sympatric three-spined and nine-spined stickleback. Read More

Acclimation effect on fish behavioural characteristics: determination of appropriate acclimation period for different species.

J Fish Biol 2021 Mar 30. Epub 2021 Mar 30.

Life Sciences Center, Vilnius University, Vilnius, Lithuania.

In the present study, we investigated the effect of acclimation duration (up to 4 h) on behavioural characteristics of taxonomically and functionally different fish species, i.e., the migratory rheophilic salmonids rainbow trout (Oncorhynchus mykiss) and Atlantic salmon (Salmo salar), and the non-migratory eurytopic European perch (Perca fluviatilis) and three-spined stickleback (Gasterosteus aculeatus).

Courtship behavior, nesting microhabitat, and assortative mating in sympatric stickleback species pairs.

Ecol Evol 2021 Feb 29;11(4):1741-1755. Epub 2021 Jan 29.

School of Life Sciences University of Nottingham Nottingham UK.

The maintenance of reproductive isolation in the face of gene flow is a particularly contentious topic, but differences in reproductive behavior may provide the key to explaining this phenomenon. However, we do not yet fully understand how behavior contributes to maintaining species boundaries. How important are behavioral differences during reproduction? To what extent does assortative mating maintain reproductive isolation in recently diverged populations and how important are "magic traits"? Assortative mating can arise as a by-product of accumulated differences between divergent populations as well as an adaptive response to contact between those populations, but this is often overlooked.

Genomic evidence supports the introgression between two sympatric stickleback species inhabiting the White Sea basin.

Heliyon 2021 Feb 8;7(2):e06160. Epub 2021 Feb 8.

National Research Center "Kurchatov Institute", 123182 Moscow, Russia.

Interspecies hybridization is driven by a complex interplay of factors where introgression plays an important role. In the present study, the transfer of genetic material, between two quite distant fish species from different genera, through spontaneous hybridization was documented with dedicated molecular and bioinformatics tools. We investigate the genomic landscape of putative stickleback-relative introgression by carefully analyzing the tractable transposable elements (TE) on the admixed genome of some individuals of two sympatric stickleback species inhabiting northwestern Russia, namely the three-spined () and the nine-spined () sticklebacks.

Nest-site selection in a fish species with paternal care.

Hydrobiologia 2021 4;848(3):641-650. Epub 2020 Dec 4.

Abteilung Verhaltensökologie, Zoologisches Institut, University of Bern, Wohlenstrasse 50a, 3032 Hinterkappelen, Switzerland.

Fish that perform paternal care may increase their fitness by choosing nest sites that enhance survival and development of embryos. We studied nest-site choice with respect to dissolved oxygen concentration and water temperature in males of the three-spined stickleback (), a small fish species with exclusive male parental care that usually breeds in the littoral zone of freshwaters of the Northern hemisphere. Fathers oxygenate the embryos by fanning movements of their pectoral fins. Read More

Environment-induced changes in reproductive strategies and their transgenerational effects in the three-spined stickleback.

Ecol Evol 2021 Jan 9;11(2):771-783. Epub 2020 Dec 9.

Grupo Ecoloxía Animal (Lab 97) Torre CACTI Centro de Investigación Mariña Universidade de Vigo Vigo Spain.

An organism may increase its fitness by changing its reproductive strategies in response to environmental cues, but the possible consequences of those changes for the next generation have rarely been explored. By using an experiment on the three-spined stickleback (), we studied how changes in the onset of breeding photoperiod (early versus late) affect reproductive strategies of males and females, and life histories of their offspring. We also explored whether telomeres are involved in the within- and transgenerational effects. Read More

Cercarial behaviour alters the consumer functional response of three-spined sticklebacks.

J Anim Ecol 2021 04 8;90(4):978-988. Epub 2021 Feb 8.

Institute of Parasitology, Biology Centre, Czech Academy of Sciences, České Budějovice, Czech Republic.

Free-living parasite life stages may contribute substantially to ecosystem biomass and thus represent a significant source of energy flow when consumed by non-host organisms. However, ambient temperature and the predator's own infection status may modulate consumption rates towards parasite prey. We investigated the combined effects of temperature and predator infection status on the consumer functional response of three-spined sticklebacks towards the free-living cercariae stages of two common freshwater trematode parasites (Plagiorchis spp. Read More

Genetic population structure constrains local adaptation in sticklebacks.

Mol Ecol 2021 Jan 19. Epub 2021 Jan 19.

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

Repeated and independent adaptation to specific environmental conditions from standing genetic variation is common. However, if genetic variation is limited, the evolution of similar locally adapted traits may be restricted to genetically different and potentially less optimal solutions or prevented from happening altogether. Using a quantitative trait locus (QTL) mapping approach, we identified the genomic regions responsible for the repeated pelvic reduction (PR) in three crosses between nine-spined stickleback populations expressing full and reduced pelvic structures.

Zone of Interaction Between the Parasite and the Host: Protein Profile of the Body Cavity Fluid of Gasterosteus aculeatus L. Infected with the Cestode Schistocephalus solidus (Muller, 1776).

Acta Parasitol 2021 Jan 2. Epub 2021 Jan 2.

Institute of Biology of the Karelian Research Centre of the Russian Academy of Sciences, 185910, Petrozavodsk, Russia.

Purpose: During infection, the host and the parasite "communicate" with each other through various molecules, including proteins. The aim of this study was to describe the excretory-secretory proteins from the helminth Schistocephalus solidus and its intermediate host, the three-spined stickleback Gasterosteus aculeatus L., which are likely to be involved in interactions between them.

Variation in the Sensory Space of Three-spined Stickleback Populations.

Integr Comp Biol 2020 Dec 31. Epub 2020 Dec 31.

Department of Integrative Biology, Ecology, Evolutionary Biology and Behavior, BEACON, Michigan State University, East Lansing, MI, USA.

The peripheral sensory systems, whose morphological attributes help determine the acquisition of distinct types of information, provide a means to quantitatively compare multiple modalities of a species' sensory ecology. We used morphological metrics to characterize multiple sensory modalities-the visual, olfactory, and mechanosensory lateral line sensory systems-for Gasterosteus aculeatus, the three-spined stickleback, to compare how sensory systems vary in animals that evolve in different ecological conditions. We hypothesized that the dimensions of sensory organs and correlations among sensory systems vary in populations adapted to marine and freshwater environments, and have diverged further among freshwater lake-dwelling populations.

Dietary uptake and effects of copper in Sticklebacks at environmentally relevant exposures utilizing stable isotope-labeled CuCl and CuO NPs.

Sci Total Environ 2021 Feb 25;757:143779. Epub 2020 Nov 25.

Department of Science and Environment, Roskilde University, Denmark.

Copper oxide nanoparticles (CuO NPs) accumulating in sediment can be taken up by invertebrates that serve as prey for fish. Thus, it is likely that the latter are exposed to CuO NPs via the gut. However, to this day it is unknown if CuO NPs can be taken up via the gastrointestinal tract and if and in which tissues/organs they accumulate. Read More

Intercontinental genomic parallelism in multiple three-spined stickleback adaptive radiations.

Nat Ecol Evol 2021 02 30;5(2):251-261. Epub 2020 Nov 30.

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

Parallelism, the evolution of similar traits in populations diversifying in similar conditions, provides strong evidence of adaptation by natural selection. Many studies of parallelism focus on comparisons of different ecotypes or contrasting environments, defined a priori, which could upwardly bias the apparent prevalence of parallelism. Here, we estimated genomic parallelism associated with components of environmental and phenotypic variation at an intercontinental scale across four freshwater adaptive radiations (Alaska, British Columbia, Iceland and Scotland) of the three-spined stickleback (Gasterosteus aculeatus).

Sex-specific plasticity across generations I: Maternal and paternal effects on sons and daughters.

J Anim Ecol 2020 12 15;89(12):2788-2799. Epub 2020 Nov 15.

Department of Evolution, Ecology and Behavior, School of Integrative Biology, University of Illinois Urbana-Champaign, Urbana, IL, USA.

Intergenerational plasticity or parental effects-when parental environments alter the phenotype of future generations-can influence how organisms cope with environmental change. An intriguing, underexplored possibility is that sex-of both the parent and the offspring-plays an important role in driving the evolution of intergenerational plasticity in both adaptive and non-adaptive ways. Here, we evaluate the potential for sex-specific parental effects in a freshwater population of three-spined sticklebacks Gasterosteus aculeatus by independently and jointly manipulating maternal and paternal experiences and separately evaluating their phenotypic effects in sons versus daughters.

Multiple waves of freshwater colonization of the three-spined stickleback in the Japanese Archipelago.

BMC Evol Biol 2020 11 3;20(1):143. Epub 2020 Nov 3.

Ecological Genetics Laboratory, National Institute of Genetics, Mishima, Shizuoka, 411-8540, Japan.

Background: The three-spined stickleback (Gasterosteus aculeatus) is a remarkable system to study the genetic mechanisms underlying parallel evolution during the transition from marine to freshwater habitats. Although the majority of previous studies on the parallel evolution of sticklebacks have mainly focused on postglacial freshwater populations in the Pacific Northwest of North America and northern Europe, we recently use Japanese stickleback populations for investigating shared and unique features of adaptation and speciation between geographically distant populations. However, we currently lack a comprehensive phylogeny of the Japanese three-spined sticklebacks, despite the fact that a good phylogeny is essential for any evolutionary and ecological studies.

Parasite infection disrupts escape behaviours in fish shoals.

Proc Biol Sci 2020 11 4;287(1938):20201158. Epub 2020 Nov 4.

Institute for Evolution and Biodiversity, University of Münster, Hüfferstrasse 1, 48149 Münster, Germany.

Many prey species have evolved collective responses to avoid predation. They rapidly transfer information about potential predators to trigger and coordinate escape waves. Predation avoidance behaviour is often manipulated by trophically transmitted parasites, to facilitate their transmission to the next host. Read More

Water quality of the Meuse watershed: Assessment using a multi-biomarker approach with caged three-spined stickleback (Gasterosteus aculeatus L.).

Ecotoxicol Environ Saf 2021 Jan 15;208:111407. Epub 2020 Oct 15.

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

The use of a multi-biomarker approach with three-spined sticklebacks (Gasterosteus aculeatus) through an active biomonitoring strategy appears to be a promising tool in water quality assessment. The present work proposes to assess the efficiency of these tools in the discrimination of some sites in a large scale on the Meuse basin in Europe. The study was part of an EU program which aims to assess water quality in the Meuse across the French-Belgian border. Read More

Climate change facilitates a parasite's host exploitation via temperature-mediated immunometabolic processes.

Glob Chang Biol 2021 Jan 10;27(1):94-107. Epub 2020 Nov 10.

Institute for Evolution and Biodiversity, Animal Evolutionary Ecology, University of Münster, Münster, Germany.

Global climate change can influence organismic interactions like those between hosts and parasites. Rising temperatures may exacerbate the exploitation of hosts by parasites, especially in ectothermic systems. The metabolic activity of ectotherms is strongly linked to temperature and generally increases when temperatures rise. Read More

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

Identification of key proteins involved in stickleback environmental adaptation with system-level analysis.

Physiol Genomics 2020 11 21;52(11):531-548. Epub 2020 Sep 21.

Department of Biotechnology and Food Science, Norwegian University of Science and Technology, Trondheim, Norway.

Using abundance measurements of 1,490 proteins from four separate populations of three-spined sticklebacks, we implemented a system-level approach to correlate proteome dynamics with environmental salinity and temperature and the fish's population and morphotype. We identified robust and accurate fingerprints that classify environmental salinity, temperature, morphotype, and the population sample origin, observing that proteins with specific functions are enriched in these fingerprints. Highly apparent functions represented in all fingerprints include ion transport, proteostasis, growth, and immunity, suggesting that these functions are most diversified in populations inhabiting different environments.

A spatial regime shift from predator to prey dominance in a large coastal ecosystem.

Commun Biol 2020 Aug 27;3(1):459. Epub 2020 Aug 27.

Department of Aquatic Resources, Swedish University of Agricultural Sciences, Öregrund, Sweden.

Regime shifts in ecosystem structure and processes are typically studied from a temporal perspective. Yet, theory predicts that in large ecosystems with environmental gradients, shifts should start locally and gradually spread through space. Here we empirically document a spatially propagating shift in the trophic structure of a large aquatic ecosystem, from dominance of large predatory fish (perch, pike) to the small prey fish, the three-spined stickleback.

Naproxen affects multiple organs in fish but is still an environmentally better alternative to diclofenac.

Aquat Toxicol 2020 Oct 28;227:105583. Epub 2020 Jul 28.

Section of Pathology, Department of Biomedical Sciences and Veterinary Public Health, Swedish University of Agricultural Sciences, Uppsala, Sweden.

The presence of diclofenac in the aquatic environment and the risks for aquatic wildlife, especially fish, have been raised in several studies. One way to manage risks without enforcing improved wastewater treatment would be to substitute diclofenac (when suitable from a clinical perspective) with another non-steroidal anti-inflammatory drug (NSAID) associated with less environmental risk. While there are many ecotoxicity-studies of different NSAIDs, they vary extensively in set-up, species studied, endpoints and reporting format, making direct comparisons difficult. Read More

Partitioning the environmental drivers of immunocompetence.

Sci Total Environ 2020 Dec 25;747:141152. Epub 2020 Jul 25.

School of Biosciences, Cardiff University, Cardiff, UK.

By determining susceptibility to disease, environment-driven variation in immune responses can affect the health, productivity and fitness of vertebrates. Yet how the different components of the total environment control this immune variation is remarkably poorly understood. Here, through combining field observation, experimentation and modelling, we are able to quantitatively partition the key environmental drivers of constitutive immune allocation in a model wild vertebrate (three-spined stickleback, Gasterosteus aculeatus).

Phenotypic flexibility in background-mediated color change in sticklebacks.

Behav Ecol 2020 Jul-Aug;31(4):950-959. Epub 2020 May 6.

Ecology and Evolution in Microbial Model Systems, EEMiS, Department of Biology and Environmental Science, Linnaeus University, Kalmar, Sweden.

Phenotypic flexibility may incur a selective advantage in changing and heterogeneous environments, and is increasingly recognized as an integral aspect of organismal adaptation. Despite the widespread occurrence and potential importance of rapid and reversible background-mediated color change for predator avoidance, knowledge gaps remain regarding its adaptive value, repeatability within individuals, phenotypic correlates, and whether its expression is context dependent. We used manipulative experiments to investigate these issues in two fish species, the three-spined stickleback () and nine-spined stickleback (). Read More

Prior exposure to long-day photoperiods alters immune responses and increases susceptibility to parasitic infection in stickleback.

Proc Biol Sci 2020 07 1;287(1930):20201017. Epub 2020 Jul 1.

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

Seasonal disease and parasitic infection are common across organisms, including humans, and there is increasing evidence for intrinsic seasonal variation in immune systems. Changes are orchestrated through organisms' physiological clocks using cues such as day length. Ample research in diverse taxa has demonstrated multiple immune responses are modulated by photoperiod, but to date, there have been few experimental demonstrations that photoperiod cues alter susceptibility to infection.

On the causes of geographically heterogeneous parallel evolution in sticklebacks.

Nat Ecol Evol 2020 08 22;4(8):1105-1115. Epub 2020 Jun 22.

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

The three-spined stickleback (Gasterosteus aculeatus) is an important model system for the study of parallel evolution in the wild, having repeatedly colonized and adapted to freshwater from the sea throughout the northern hemisphere. Previous studies identified numerous genomic regions showing consistent genetic differentiation between freshwater and marine ecotypes but these had typically limited geographic sampling and mostly focused on the Eastern Pacific region. We analysed population genomic data from global samples of the three-spined stickleback marine and freshwater ecotypes to detect loci involved in parallel evolution at different geographic scales.
