References to "Umwelt ethics" and "Umwelt transitions" in Favareau's "Commentary Bibliography and Further Readings"

A number of references to my 2003 article "Umwelt ethics" (Sign Systems Studies 31 (1): 281-299) and my 2009 article "Umwelt transitions: Uexküll and environmental change" (Biosemiotics 2 (1): 47-64) are included in Donald Favareau's bibliography in Essential Readings in Biosemiotics: Anthology and Commentary. I'm furthermore listed in the index (see my blogpost "References" from August 2010, which refers to Favareau's mention of Tønnessen 2003 in the same book's "Introduction: An evolutionary history of biosemiotics"). Reference to the bibliography, and the references to my work:
