From Wikipedia —

In the context of an evolving information society, the term information ecology marks a connection between ecological ideas with the dynamics and properties of the increasingly dense, complex and important digital informational environment and has been gaining progressively wider acceptance in a growing number of disciplines. “Information ecology” often is used as metaphor, viewing the informational space as an ecosystem.

Information ecology is a science which studies the laws governing the influence of information summary on the formation and functioning of bio?systems, including that of individuals, human communities and humanity in general and on the health and psychological, physical and social well?being of the human being; and which undertakes to develop methodologies to improve the information environment (Eryomin 1998).

Information ecology also makes a connection to the concept of collective intelligence and knowledge ecology (Pór 2000)

“We define an information ecology to be a system of people, practices, values, and technologies in a particular local environment. In information ecologies, the spotlight is not on technology, but on human activities that are served by technology.

“A library is an information ecology. It is a place with books, magazines, tapes, films, and librarians who can help you find and use them. A library may have computers, as well as story time for two-year-olds and after-school study halls for teens. In a library, access to information for all clients of the library is a core value. This value shapes the policies around which the library is organized, including those relating to technology. A library is a place where people and technology come together in congenial relations, guided by the values of the library.”
