Ecological Dynamics and Social Behavior of Eurasian Badgers
Summary
The Eurasian badger (Meles meles) is a medium-sized mustelid whose ecological success rests on a combination of flexible foraging strategies, communal burrow systems and intricate social organisation. Found across diverse habitats from woodlands to agricultural landscapes, badgers excavate extensive underground setts that function as breeding dens, hibernation refuges and social centres. Individuals live in stable social groups, or clans, whose composition is shaped by kinship ties, resource availability and inter-group interactions. Foraging is opportunistic, encompassing earthworms, insect larvae, small vertebrates and plant matter, with seasonal shifts in diet and nightly ranging patterns driven by climatic conditions and energetic demands. Reproductive biology features delayed implantation and potential superfetation, enabling females to synchronise cub emergence with optimal resource periods. Energy budgets vary markedly with age, sex and reproductive status, underpinning life-history trade-offs that influence survival and body condition. Social contacts at communal latrines and sett entrances facilitate information exchange, coalition formation and extra-group mating, while also mediating disease transmission. Badgers are recognised as ecosystem engineers: their soil-disturbing activities enhance soil aeration, nutrient cycling and plant community heterogeneity, and their seed dispersal fosters woodland regeneration. Together, these traits render Meles meles a keystone species with far-reaching impacts on ecosystem structure and function.

Ecological Dynamics and Social Behavior of Eurasian Badgers publication trend
The graph below shows the total number of articles in ecological dynamics and social behavior of eurasian badgers across all publications each year (not limited to Nature Index journals).
Technical terms
Overall dynamic body acceleration (ODBA): a proxy measure of individual movement-related energy expenditure derived from tri-axial accelerometry data.
Sett: a communal underground burrow system excavated and maintained by Eurasian badgers that serves as shelter, breeding site and social hub.
Extra-group paternity: the occurrence of offspring sired by males outside an individual’s social group, indicating inter-group mating and gene flow.
Group density: the number of social groups per unit area, a component of population density in group-living species.
