Media ecology is an interdisciplinary field that resists the study of media forms in isolation. For our first issue of the 2009 volume, the editors of InterCulture sought work engaged with the field of media ecology that denaturalized dualistic structures, questioned essentializing hierarchies, and hunted liminal spaces. The following four articles in this issue on “Media Ecologies” are the result of our search. Together, they create a sense of ebb and flow appropriate to the fluidity pervasive in the conceptual paradigm of media ecologies.
