The spatial distribution of avian relatives: do obligate army-ant-following birds roost and feed near family members?

abstract：:Organisms often respond to environmental changes by producing alternative phenotypes. Epigenetic processes such as DNA methylation may contribute to environmentally induced phenotypic variation by modifying gene expression. Changes in DNA methylation, unlike DNA mutations, can be influenced by the environment; they ar...
