Threespine Stickleback: A Model System For Evolutionary Genomics

Annual Review of Genomics and Human Genetics, Journal Year: 2021, Volume and Issue: 22(1), P. 357 - 383

Published: April 28, 2021

The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a premier organism study parallel evolution. These small fish have multiple distinct ecotypes that display wide range diverse phenotypic traits. Ecotypes are easily crossed in the laboratory, and families large develop quickly enough for quantitative trait locus analyses, positioning stickleback as versatile model address biological questions. Extensive genomic resources, including linkage maps, high-quality reference genome, developmental genetics tools led insights into basis identification changes controlling traits vertebrates. Recently, been used system identify highly complex traits, such behavior host–microbiome host–parasite interactions. We review latest findings new avenues research be considered supermodel evolutionary genomics.

The epigenetics of animal personality

Neuroscience & Biobehavioral Reviews, Journal Year: 2023, Volume and Issue: 150, P. 105194 - 105194

Published: April 23, 2023

Animal personality, consistent individual differences in behaviour, is an important concept for understanding how individuals vary they cope with environmental challenges. In order to understand the evolutionary significance of animal it crucial underlying regulatory mechanisms. Epigenetic marks such as DNA methylation are hypothesised play a major role explaining variation phenotypic changes response alterations. Several characteristics also align well personality. this review paper, we summarise current literature on that molecular epigenetic mechanisms may have personality variation. We elaborate potential explain behavioural variation, development and temporal consistency behaviour. then suggest future routes emerging field point pitfalls be encountered. conclude more inclusive approach needed studying epigenetics cannot studied without considering genetic background.

Temperament and brain networks of attention

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2018, Volume and Issue: 373(1744), P. 20170254 - 20170254

The attention networks of the human brain are important control systems that develop from infancy into adulthood. While they common to everyone, differ in efficiency, forming basis individual differences attention. We have developed methods for measuring efficiency these older children and adults also examined their development infancy.

Gene regulation and speciation in a migratory divide between songbirds

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 2, 2024

Behavioral variation abounds in nature. This is important for adaptation and speciation, but its molecular basis remains elusive. Here, we use a hybrid zone between two subspecies of songbirds that differ migration - an ecologically taxonomically widespread behavior---to gain insight into this topic. We measure gene expression five brain regions. Differential migratory states was dominated by circadian genes all The remaining patterns were largely brain-region specific. For example, differences the interact with state likely help maintain reproductive isolation system documented only three Contrary to existing work on regulatory mechanisms underlying species-specific traits, lines evidence suggest trans- (vs. cis) changes underlie these no allele-specific hybrids minimal associations genomic differentiation differences. Additional shows levels often distinct (transgressive) from parental forms. contrasts functional enrichment analyses allowed us connect mitonuclear incompatibilities compensatory responses stress could exacerbate selection contribute speciation.

Mating Behavioral Function of Preoptic Galanin Neurons Is Shared between Fish with Alternative Male Reproductive Tactics and Tetrapods

Journal of Neuroscience, Journal Year: 2020, Volume and Issue: 40(7), P. 1549 - 1559

Published: Jan. 7, 2020

Understanding the contribution of neuropeptide-containing neurons to variation in social behavior remains critically important. Galanin has gained increased attention because demonstration that galanin preoptic area (POA) promote mating and parental care mammals. How widespread these mechanisms are among vertebrates essentially unexplored, especially teleost fishes, which comprise nearly one-half living vertebrate species. Teleosts with alternative reproductive tactics exhibit stereotyped patterns diverge widely between individuals within a sex. This includes midshipman have two male morphs. Type I males mate using either acoustic courtship attract females enter nest they guard or cuckoldry during steal fertilizations from nest-holding sneak satellite spawning tactic, whereas type II only cuckold. Using neural activity marker phospho-S6, we show neuron activation courting is not explained by their vocalizations, eggs, defense against cuckolders. increase observed cuckolders morph (none care). Together role mammals, results demonstrate an unexpectedly specific deep-rooted, phylogenetically shared behavioral function for POA neurons. The also point galanin-dependent circuitry as potential substrate evolution divergent phenotypes one sex provide new functional insights into how populations teleosts compare anterior hypothalamus tetrapods.
