Relative to morphological traits, we know little about how genetics influence the evolution of complex behavioural differences in nature. It is unclear how the environment influences natural variation in heritable behaviour, and whether complex behavioural differences evolve through few genetic changes, each affecting many aspects of behaviour, or through the accumulation of several genetic changes that, when combined, give rise to behavioural complexity. Here we show that in nature, oldfield… Expand

Evolution and genetics of precocious burrowing behavior in Peromyscus mice
TLDR
It is reported that Peromyscus polionotus is strikingly precocious with regard to burrowing behavior, but not other behaviors, compared to its sister species P. maniculatus, and in backcross F2 hybrids, it is shown that precocious burrowing and adult tunnel length are genetically correlated, and that a single P. polionOTus allele in a genomic region linked toAdult tunnel length is predictive of precociousBurrow construction. Expand
Peromyscus burrowing: A model system for behavioral evolution.
TLDR
Potential mechanisms driving variation in burrows are discussed with an emphasis on two sister species: P. maniculatus, which digs a simple, short burrow, and P. polionotus,Which digs a long burrow with a complex architecture. Expand
Evolutionary genetics: Genes for home-building
TLDR
It is shown that the complex burrows created by oldfield mice are governed by several genetic modules, each controlling an aspect of burrow size or shape, which suggests that complex behaviour may result from the combination of genetically determined behaviours that have accumulated over time. Expand
Evolution and Genetics of Precocious Burrowing Behavior in Peromyscus Mice
TLDR
It is reported that Peromyscus polionotus is strikingly precocious with regard to burrowing behavior, but not other behaviors, compared to its sister species P. maniculatus, and in backcross hybrids, it is shown that precocious burrowing and adult tunnel length are genetically correlated. Expand
The Genetic Basis of Behavior: Burrow Construction in Deer Mice (Genus Peromyscus)
TLDR
This dissertation capitalizes on striking behavioral differences between two interfertile sister species of Peromyscus rodents to pursue the proximate mechanisms underlying this behavioral adaptation by investigating both the ontogeny and genetics of innate differences in burrow construction behavior in P. polionotus and P. maniculatus. Expand
Cis-regulatory changes in locomotor genes are associated with the evolution of burrowing behavior
TLDR
Insight is provided into how cis-regulated gene expression can depend on behavioral context as well as how this dynamic regulatory divergence between species can be integrated with forward genetics to enrich the understanding of the genetic basis of behavioral evolution. Expand
Behavioural mechanisms underlying the evolution of cooperative burrowing in Peromyscus mice
TLDR
This work designs a novel behavioural assay in which it is found that longer burrows are achieved not by changing individual behaviour, but instead because opposite-sex pairs are more socially cohesive and thus more likely to dig simultaneously, which is a more efficient mode of burrow elongation. Expand
Genetic and Neural Modularity Underlie the Evolution of Schooling Behavior in Threespine Sticklebacks
TLDR
This work performed quantitative trait locus analysis of schooling in an F2 intercross between strongly schooling marine and weakly schooling benthic sticklebacks and found that distinct genetic modules control different aspects of schooling behavior. Expand
The genetic architecture of adaptation: convergence and pleiotropy in Heliconius wing pattern evolution
TLDR
QTL analyses of crosses between H. melpomene races from Peru and Suriname are used to map, for the first time, the control of the broken band phenotype to WntA and identify a ~100 kb region controlling this variation. Expand
Genetic dissection of adaptive form and function in rapidly speciating cichlid fishes
TLDR
The results indicate that the evolution of the Lake Victoria thick‐lipped ecomorph is the result of selection on numerous loci distributed throughout the genome, rather than being based on few major loci with strong positive genetic correlations. Expand

The evolution of burrowing behaviour in deer mice (genus Peromyscus)
TLDR
It is found that several, but not all, species burrow even after many generations of captive breeding, and that the most complex burrows probably evolved by the gradual accumulation of genetic change over time. Expand
The genetic architecture of divergence between threespine stickleback species
TLDR
A genome-wide linkage map is developed for the three-spined stickleback (Gasterosteus aculeatus), an extensively studied teleost fish that has undergone rapid divergence and speciation since the melting of glaciers 15,000 years ago. Expand
Inheritance of burrow building inPeromyscus
TLDR
F1 hybrid data indicate that the more complex burrow building exhibits genetic dominance, and backcross results show that at least two and probably more gene loci strongly influence the trait. Expand
Adaptive Variation in Beach Mice Produced by Two Interacting Pigmentation Genes
TLDR
It is demonstrated that cryptic coloration can be based largely on a few interacting genes of major effect, including the melanocortin-1 receptor (Mc1r) and its antagonist, the Agouti signaling protein (Agouti). Expand

TLDR
The candidate gene approach provides an accessible and useful tool for generating insights about animals that are not typically associated with genetic experimentation and offers great potential to expand the understanding of behavioural ecology. Expand

TLDR
This article reviews how genetic analyses of behavior are central to topics ranging from understanding past selection and predicting future evolution to explaining the neural and hormonal control of behavior and shows the great promise for evolutionary behavioral genetics. Expand

TLDR
It is suggested that gene–environment interactions are central to natural genetic variation in behaviour and that genes affecting neuromodulatory pathways and sensory processing are preferred sites of naturally occurring mutations. Expand

This approach is broadly applicable in terms of phenotypes and model organisms and allows GWAS to be performed in multigenerational crosses between and among inbred strains where familial relatedness is often unavoidable. Expand

Complete genome sequences and improved technologies for polymorphism detection will greatly advance the genetic dissection of quantitative traits in model organisms, which will open avenues for exploration of homologous QTL in related taxa. Expand
