There is now mounting evidence that heritable variation in ecologically relevant traits can be generated through a suite of epigenetic mechanisms, even in the absence of genetic variation. Moreover, recent studies indicate that epigenetic variation in natural populations can be independent from genetic variation, and that in some cases environmentally induced epigenetic changes may be inherited by future generations. These novel findings are potentially highly relevant to ecologists because…

Ecological epigenetics: an introduction to the symposium.
TLDR
By characterizing environmentally dependent epigenetic variation in natural populations, this issue will enhance the understanding of developmental, ecological, and evolutionary phenomena and introduce some of the common goals and challenges shared by those pursuing this critical field.
Epigenetics in natural animal populations
TLDR
This review provides an overview of recent studies on epigenetically encoded thermal plasticity in animals to illustrate environmentally‐mediated epigenetic effects within and across generations and evaluates the evolutionary potential of epigenetic variation depending on its autonomy from genetic variation and its transgenerational stability.
Epigenetics for behavioral ecologists
TLDR
This review highlights the advances that have been made toward understanding molecular epigenetic mechanisms underlying behavioral variation, and proposes approaches and systems that will be amenable to the study of behavioral epigenetics in natural populations.
Avian ecological epigenetics: pitfalls and promises
TLDR
The potential for studying epigenetic variation in natural bird systems is reviewed, how findings on other taxa such as plants and mammals relate to birds are examined, and some topics need to be addressed to develop the field of wild avian epigenetics further.
The role of epigenetics in plant adaptation
TLDR
It is suggested that modern evolutionary theory will benefit from the incorporation of epigenetics, but it is not in need of a complete revision, as has been suggested.
Epigenetic Inheritance across the Landscape
TLDR
It is suggested that multi-generation common garden experiments conducted across multiple environments will allow researchers to understand which parts of the epigenome are inherited, as well as to parse out the relative contribution of heritable epigenetic variation to the phenotype.
What Role Does Heritable Epigenetic Variation Play in Phenotypic Evolution?
TLDR
It is found that understanding the relevance of epigenetic effects in phenotypic evolution will require clearly delineating epigenetics within existing terminology and expanding research efforts into ecologically relevant circumstances across model and nonmodel organisms.
A truly ecological epigenetics study
TLDR
The study of variation of DNA methylation in a wild population of the rare, long‐lived violet Viola cazorlensis is used to explore interrelations between environmental, genetic and epigenetic variation, and in particular the extent to which these factors are related to long‐term differences in herbivore damage among plants.
Uncovering the contribution of epigenetics to plant phenotypic variation in Mediterranean ecosystems.
TLDR
There is still much to be learned about 'plant epigenetics in the wild' and, thus, future research steps in the study of natural epigenetic variation of key traits in the MTEs at different scales are proposed.
How might epigenetics contribute to ecological speciation
TLDR
There is mounting evidence for environmentally induced epigenetic variation and for the stable inheritance of epigenetic marks between generations in animals, and epigenetically-based pheno- typic plasticity may play a role in adaptation and ecological speciation.

IDEA AND PERSPECTIVE Epigenetics for ecologists
TLDR
Ecologists should start using a combination of experimental approaches borrowed from ecological genetics, novel techniques to analyse and manipulate epigenetic variation, and genomic tools, to investigate the extent and structure of epigenetics variation within and among natural populations, as well as the interrelations between epigenetic variations, phenotypic variation and ecological interactions.
Epigenetics and plant evolution.
TLDR
An introduction to epigenetic mechanisms in plants is provided, and some of the empirical studies illustrative of the possible connections between evolution and epigenetically mediated alterations in gene expression and morphology are highlighted.
Epialleles via DNA methylation: consequences for plant evolution.
Epigenetics and its implications for plant biology 2. The 'epigenetic epiphany': epigenetics, evolution and beyond.
TLDR
It is suggested that the ramifications of epigenetics in plant biology are immense, yet unappreciated, and greater knowledge of patterns of epigenetic variation may be informative in taxonomy and systematics, as well as population biology and conservation.
Epigenetic phenomena and the evolution of plant allopolyploids.
Epigenetics and its implications for plant biology. 1. The epigenetic network in plants.
TLDR
How epigenetic systems in plants were elucidated is addressed and there is a discussion on how the different components of the epigenetic system--regulating DNA methylation, histones and their post-translational modification, and pathways recognizing aberrant transcripts--may work together.
Multigenerational selection and detection of altered histone acetylation and methylation patterns: toward a quantitative epigenetics in Drosophila.
TLDR
A case study for QE analysis-epigenetic mapping of enhancers of the KrIf-1 ectopic eye bristle phenotype in an isogenic strain of Drosophila melanogaster is presented, showing how the positioning of epialleles defined by chromatin variation to individual genes or chromosomal regions can be determined even in the absence of DNA sequence variation.
Epigenetic regulation of gene expression: how the genome integrates intrinsic and environmental signals
TLDR
Advances in the understanding of the mechanism and role of DNA methylation in biological processes are reviewed, showing that epigenetic mechanisms seem to allow an organism to respond to the environment through changes in gene expression.
How lifetimes shape epigenotype within and across generations.
TLDR
Over the next decade, many of these processes will be better understood, heralding a greater capacity for us to correlate measurable molecular marks with phenotype and providing the opportunity for improved diagnosis and presymptomatic healthcare.
Environmental epigenomics and disease susceptibility
TLDR
An increasing body of evidence from animal studies supports the role of environmental epigenetics in disease susceptibility and recent studies have demonstrated for the first time that heritable environmentally induced epigenetic modifications underlie reversible transgenerational alterations in phenotype.
